Summary Of Significant Accounting Policies	12 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Timberland Bancorp, Inc. (“Timberland Bancorp”); its wholly owned subsidiary, Timberland Bank (the “Bank”); and the Bank’s wholly owned subsidiary, Timberland Service Corp. (collectively,  “the Company”).  All significant intercompany transactions and balances have been eliminated in consolidation.
	Nature of Operations
	Timberland Bancorp is a bank holding company which operates primarily through its subsidiary, the Bank.  The Bank was established in 1915 and, through its 22 branches located in Grays Harbor, Pierce, Thurston, Kitsap, King and Lewis counties in Washington State, attracts deposits from the general public, and uses those funds, along with other borrowings, primarily to provide residential real estate, construction, commercial real estate, commercial business and consumer loans to borrowers primarily in western Washington.
	Consolidated Financial Statement Presentation
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S.")(“GAAP”) and prevailing practices within the banking industry.  The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities, as of the date of the consolidated balance sheet, and the reported amounts of income and expenses during the reporting period.  Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of OTTI in the estimated fair value of MBS, the valuation of MSRs, the valuation of OREO and the valuation of goodwill for potential impairment.
	Certain prior year amounts have been reclassified to conform to the 2014 fiscal year presentation with no change to previously reported net income or shareholders’ equity.
	Segment Reporting
	The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name “Timberland Bank.”
	Preferred Stock Sold in Troubled Asset Relief Program ("TARP") Capital Purchase Program ("CPP")
	On December 23, 2008, the Company received $16.64 million from the U.S. Treasury Department ("Treasury") as a part of the Treasury's CPP, which was established as part of the TARP. The Company sold 16,641 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A ("Series A Preferred Stock"), with a liquidation value of $1,000 per share and a related warrant to purchase 370,899 shares of the Company's common stock at an exercise price of $6.73 per share (subject to anti-dilution adjustments) at any time through December 23, 2018. The Series A Preferred Stock paid a 5.0% dividend through December 20, 2013, the date of its redemption.
	The proceeds received in connection with the issuance of the Series A Preferred Stock were allocated between the preferred stock and warrant based on their relative fair values on the date of issuance. As a result, the preferred stock's initial recorded value was at a discount from the liquidation value or stated value. The discount from the liquidation value was accreted to the expected/actual redemption date and charged to retained earnings. This accretion was recorded using the level-yield method.
	On November 13, 2012, the Company’s outstanding 16,641 shares of Series A Preferred Stock were sold by the Treasury as part of Treasury's efforts to manage and recover its investments under the TARP. While the sale of this preferred stock to new owners did not result in any proceeds to the Company and did not change the Company’s capital position or accounting for these securities, it did eliminate restrictions put in place by the Treasury on TARP recipients.
	On June 12, 2013, the Treasury sold the warrant to purchase up to 370,899 shares of the Company’s common stock to private investors.  The sale of the warrant to new owners did not result in any proceeds to the Company and did not change the Company's capital position or accounting for the warrant.
	During the year ended September 30, 2013, the Company purchased and retired 4,576 shares of its Series A Preferred Stock for $4.32 million; a $255,000 discount from its liquidation value. The discount from liquidation value on the repurchased shares was recorded as an increase to retained earnings. On December 20, 2013, the Company redeemed the remaining 12,065 shares of its Series A Preferred Stock at the liquidation value of $12.07 million.
	Investment Securities
	Securities are classified upon acquisition as either held to maturity or available for sale.  Securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reflected at amortized cost.  Securities classified as available for sale are reflected at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of tax effects.  Premiums and discounts are amortized to earnings using the interest method over the contractual life of the securities.  Gains and losses on sales of securities are recognized on the trade date and determined using the specific identification method.
	In estimating whether there are any OTTI losses, management considers (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) the financial condition and near term prospects of the issuer, (3) the impact of changes in market interest rates and (4) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value.
	Declines in the fair value of individual securities available for sale that are deemed to be other than temporary are reflected in earnings when identified.  The fair value of the security then becomes the new cost basis.  For individual securities which the Company does not intend to sell and it is not more likely than not that the Company will be required to sell before recovery of its amortized cost basis, the other than temporary decline in the fair value of the security related to: (1) credit loss is recognized in earnings and (2) market or other factors is recognized in other comprehensive income (loss).  Credit loss is recorded if the present value of cash flows is less than the amortized cost.  For individual securities which the Company intends to sell or more likely than not will not recover all of its amortized cost, the OTTI is recognized in earnings equal to the entire difference between the security’s cost basis and its fair value at the consolidated balance sheet date.  For individual securities for which credit loss has been recognized in earnings, interest accruals and amortization and accretion of premiums and discounts are suspended when the credit loss is recognized.  Interest received after accruals have been suspended is recognized on a cash basis.
	FHLB Stock
	The Company, as a member of the FHLB, is required to maintain an investment in capital stock of the FHLB in an amount equal to the greater of 1% of its outstanding home loans or 5% of advances from the FHLB.  No ready market exists for this stock, and it has no quoted market value. However, redemption of this stock has historically been at par value. The Company's investment in FHLB stock is carried at cost, which approximates fair value.
	The Company evaluates its FHLB stock for impairment as needed. The Company's determination of whether this investment is impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared with the capital stock amount and the length of time any decline has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (4) the liquidity position of the FHLB. The FHLB has recently announced it has entered into an agreement to merge with the Federal Home Loan Bank of Des Moines. Although the agreement is still in process and has not yet been finalized and approved by certain regulatory agencies, management expects that the pending merger will positively affect the Company's recoverability of its investment in FHLB stock and continue to allow the Bank to obtain borrowings consistent with historical FHLB funding practices. Based on its evaluation, the Company determined that there was no impairment of FHLB stock at September 30, 2014 and 2013.
	Loans Held for Sale
	Mortgage loans originated and intended for sale in the secondary market are stated in the aggregate at the lower of cost or estimated fair value.  Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.  Gains or losses on sales of loans are recognized at the time of sale.  The gain or loss is the difference between the net sales proceeds and the recorded value of the loans, including any remaining unamortized deferred loan origination fees.
	Loans Receivable
	Loans are stated at the amount of unpaid principal, reduced by the undisbursed portion of construction loans in process, deferred loan origination fees and the allowance for loan losses.
	Non-Performing Loans
	Loans on non-accrual status and loans past due 90 days or more and still accruing interest are considered to be non-performing loans.
	Troubled Debt Restructured Loans
	A troubled debt restructured loan is a loan for which the Company, for reasons related to a borrower’s financial difficulties, grants a significant concession to the borrower that the Company would not otherwise consider.
	The loan terms which have been modified or restructured due to a borrower’s financial difficulty, include but are not limited to: a reduction in the stated interest rate; an extension of the maturity at an interest rate below current market rates; a reduction in the face amount of the debt; a reduction in the accrued interest; or re-amortizations, extensions, deferrals and renewals. Troubled debt restructured loans are considered impaired and are individually evaluated for impairment. Troubled debt restructured loans are classified as non-performing unless they have been performing in accordance with modified terms for a period of at least six months.
	Impaired Loans
	A loan is generally considered impaired when it is probable that the Company will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement.  When a loan is considered collateral dependent, impairment is measured using the estimated fair value of the underlying collateral, less any prior liens, and when applicable, less estimated selling costs.  For impaired loans that are not collateral dependent, impairment is measured using the present value of expected future cash flows, discounted at the loan’s original effective interest rate.
	The categories of non-accrual loans and impaired loans overlap, although they are not identical.  The Company considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the estimated collateral value, reasons for the delay, payment record, the amount past due and the number of days past due.
	Allowance for Loan Losses
	The allowance for loan losses is maintained at a level sufficient to provide for estimated loan losses based on evaluating known and inherent risks in the loan portfolio.  The allowance is provided based upon management's comprehensive analysis of the pertinent factors underlying the quality of the loan portfolio.  These factors include changes in the amount and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions, and a detailed analysis of individual loans for which full collectability may not be assured.  The detailed analysis includes methods to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment.  The allowance consists of specific and general components.  The specific component relates to loans that are deemed impaired.  For such loans that are classified as impaired, an allowance is established when the discounted cash flows, collateral value less selling costs (if applicable), or observable market price of the impaired loan is lower than the recorded value of that loan.  The general component covers non-classified loans and classified loans that are not evaluated individually for impairment and is based on historical loss experience adjusted for qualitative factors.  The Company's historical loss experience is determined by evaluating the average net charge-offs over the most recent economic cycle, but not to exceed six years. Qualitative factors are determined by loan type and allow management to adjust reserve levels to reflect the current general economic environment and portfolio performance trends including recent charge-off trends.  Allowances are provided based on management’s continuing evaluation of the pertinent factors underlying the quality of the loan portfolio, including changes in the size and composition of the loan portfolio, actual loan loss experience, current economic conditions, collateral values, geographic concentrations, seasoning of the loan portfolio, specific industry conditions, the duration of the current business cycle and regulatory requirements and expectations.  The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time consolidated financial statements are prepared.
	In accordance with GAAP, a loan is considered impaired when it is probable that a creditor will be unable to collect all amounts (principal and interest) due according to the contractual terms of the loan agreement. Smaller balance homogeneous loans, such as residential mortgage loans and consumer loans, may be collectively evaluated for impairment. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as an alternative, the current estimated fair value of the collateral, reduced by estimated costs to sell (if applicable), or observable market price is used. The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions.  Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate in determining the estimated fair value of particular properties.  In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals.  Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest and net deferred loan origination fees or costs), impairment is recognized by creating or adjusting an allocation of the allowance for loan losses and uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance.
	A provision for loan losses is charged against operations and is added to the allowance for loan losses based on a quarterly comprehensive analysis of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications and actual loss experience of the loan portfolio.  While management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety.
	The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. The Company has experienced a significant decline in valuations for some real estate collateral since October 2008.  If real estate values decline further and as updated appraisals are received on collateral for impaired loans, the Company may need to increase the allowance for loan losses appropriately. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
	Interest on Loans and Loan Fees
	Interest on loans is accrued daily based on the principal amount outstanding.  Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless they are well secured and in the process of collection.  In determining whether a borrower may be able to meet payments as they become due, management considers circumstances such as the financial strength of the borrower, the estimated collateral value, reasons for the delays in payments, payment record, the amounts past due and the number of days past due.  All interest accrued but not collected for loans that are placed on non-accrual status or charged off is reversed against interest income.  Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal.  Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, in the case of one- to four-family loans, when the loan is less than 90 days delinquent.
	The Company charges fees for originating loans.  These fees, net of certain loan origination costs, are deferred and amortized to income, on the level-yield basis, over the loan term.  If the loan is repaid prior to maturity, the remaining unamortized deferred loan origination fee is recognized in income at the time of repayment.
	MSRs
	The Company holds rights to service loans that it has originated and sold to the Federal Home Loan Mortgage Corporation (“Freddie Mac”). MSRs are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained and are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income.  The value of MSRs at the date of the sale of loans is estimated based on the discounted present value of expected future cash flows using key assumptions for servicing income and costs and prepayment rates on the underlying loans.  The estimated fair value is periodically evaluated for impairment by comparing actual cash flows and estimated future cash flows from the servicing assets to those estimated at the time the servicing assets were originated.  Fair values are estimated using discounted cash flows based on current market rates of interest.  For purposes of measuring impairment, the MSRs must be stratified by one or more predominant risk characteristics of the underlying loans.  The Company stratifies its capitalized MSRs based on product type and term of the underlying loans.  The amount of impairment recognized is the amount, if any, by which the amortized cost of the MSRs exceeds their fair value.  Impairment, if deemed temporary, is recognized through a valuation allowance to the extent that fair value is less than the recorded amount.
	BOLI
	BOLI policies are recorded at their cash surrender value less applicable cash surrender charges.  Income from BOLI is recognized when earned.
	Goodwill
	Goodwill is initially recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired.  Goodwill is presumed to have an indefinite useful life and is analyzed annually for impairment.  An annual review is performed during the third quarter of each fiscal year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired.  If the estimated fair value of the Company’s sole reporting unit exceeds the recorded value of the reporting unit, goodwill is not considered impaired and no additional analysis is necessary.
	The goodwill impairment test involves a two-step process. Step one estimates the fair value of the reporting unit. If the estimated fair value of the Company's sole reporting unit, the Bank, under step one exceeds the recorded value of the reporting unit, goodwill is not considered impaired and no further analysis is necessary. If the estimated fair value of the Company's sole reporting unit is less than the recorded value, then a step two test test, which calculates the fair value of assets and liabilities to calculate an implied value of goodwill, is performed.
	Step one of the goodwill impairment test estimated the fair value of the reporting unit utilizing a discounted cash flow income approach analysis, a public company market approach analysis, a merger and acquisition market approach analysis and a trading price market approach analysis in order to derive an enterprise value for the Company.
	The discounted cash flow income approach analysis uses a reporting unit's projection of estimated operating results and cash flows and discounts them using a rate that reflects current market conditions. The projection uses management's estimates of economic and market conditions over the projected period including growth rates in loans and deposits, estimates of future expected changes in net interest margins and cash expenditures. Key assumptions used by the Company in its discounted cash flow model (income approach) included an annual growth rate that ranged from 3.00% to 5.10%, an annual deposit growth rate that ranged from 2.80% to 4.00% and a return on assets that ranged from 0.70% to 1.00%. In addition to the above projections of estimated operating results, key assumptions used to determine the fair value estimate under the approach were the discount rate of 13.6% and the residual capitalization rate of 10.6%. The discount rate used was the cost of equity capital. The cost of equity capital was based on the capital asset pricing model ("CAPM"), modified to account for a small stock premium. The small stock premium represents the additional return required by investors for small stocks based on the Stocks, Bonds, Bills and Inflation 2013 Yearbook. Beyond the approximate five-year forecast period, residual free cash flows were estimated to increase at a constant rate into perpetuity. These cash flows were converted to a residual value using an appropriate residual capitalization rate. The residual capitalization rate was equal to the discount rate minus the expected long-term growth rate of cash flows. Based on historical results, the economic climate, the outlook for the industry and management's expectations, a long-term growth rate of 3.0% was estimated.
	The public company market approach analysis estimates the fair value by applying cash flow multiples to the reporting unit's operating performance. The multiples are derived from comparable publicly traded companies with operating and investment characteristics similar to those of the Company. Key assumptions used by the Company included the selection of comparable public companies and performance ratios. In applying the public company analysis, the Company selected eight publicly traded institutions based on similar lines of business, markets, growth prospects, risks and firm size. The performance ratios included price to earnings (last twelve months), price to earnings (current year to date), price to book value, price to tangible book value and price to deposits.
	The merger and acquisition market approach analysis estimates the fair value by using merger and acquisition transactions involving companies that are similar in nature to the Company. Key assumptions used by the Company included the selection of comparable merger and acquisition transactions and valuation ratios to be used. The analysis used banks located in Washington or Oregon that were acquired after January 1, 2012. The valuation ratios from these transactions for price to earnings and price to tangible book value were then used to derive an estimated fair value of the Company.
	The trading price market approach analysis used the closing market price at May 30, 2014 of the Company's common stock, traded on the NASDAQ Global Market to determine the market value of total equity capital.
	A key assumption used by the Company in the public company market approach analysis and the trading price market approach analysis was the application of a control premium. The Company's common stock is thinly traded and therefore management believes the trading price reflects a discount for illiquidity. In addition, the trading price of the Company's common stock reflects a minority interest value. To determine the fair market value of a majority interest in the Company's stock, premiums were calculated and applied to the indicated values. Therefore, a control premium was applied to the results of the public company market approach analysis and the trading price market approach analysis because the initial value conclusion was based on minority interest transactions. Merger and acquisition studies were analyzed to conclude that the difference between the acquisition price and a company's stock price prior to acquisition indicates, in part, the price effect of a controlling interest. Based on the evaluation of merger and acquisition studies, a control premium of 25% was used.
	The Company performed its fiscal year 2014 goodwill impairment test during the quarter ended June 30, 2014 with the assistance of a third-party firm specializing in goodwill impairment valuations for financial institutions. The third-party analysis was conducted as of May 31, 2014 and the step one test concluded that the reporting unit's fair value was more than its recorded value and, therefore, step two of the analysis was not necessary. Accordingly, the recorded value of goodwill as of May 31, 2014 was not impaired.
	A significant amount of judgment is involved in determining if an indicator of goodwill impairment has occurred. Such indicators may include, among others: a significant decline in the expected future cash flows; a sustained significant decline in the Company's stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse assessment or action by a regulator; and unanticipated competition. Key assumptions used in the annual goodwill impairment test are highly judgmental and include: selection of comparable companies, amount of control premium, projected cash flows and discount rate applied to projected cash flows. Any change in these indicators or key assumptions could have a significant negative impact on the Company's financial condition, impact the goodwill impairment analysis or cause the Company to perform a goodwill impairment analysis more frequently than once per year.
	As of September 30, 2014, management believed that there had been no events or changes in the circumstances since May 31, 2014 that would indicate a potential impairment of goodwill. No assurances can be given, however, that the Company will not record an impairment loss on goodwill in the future.
	CDI
	The CDI is amortized to non-interest expense using an accelerated method over a ten-year period.
	Premises and Equipment
	Premises and equipment are recorded at cost.  Depreciation is computed using the straight-line method over the following estimated useful lives:  buildings and improvements - five to 40 years; furniture and equipment - three to seven years; and automobiles - five years.  The cost of maintenance and repairs is charged to expense as incurred.  Gains and losses on dispositions are reflected in earnings.
Impairment of Long-Lived Assets
Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the recorded amount of an asset may not be recoverable.  Recoverability of assets to be held and used is measured by a comparison of the recorded amount of an asset to future net cash flows expected to be generated by the asset.  If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the recorded amount of the assets exceeds the discounted recovery amount or estimated fair value of the assets.  No events or changes in circumstances have occurred during the years ended September 30, 2014 or 2013 that would cause management to evaluate the recoverability of the Company’s long-lived assets.
OREO and Other Repossessed Assets
OREO and other repossessed assets consist of properties or assets acquired through or in lieu of foreclosure, and are recorded initially at the estimated fair value of the properties less estimated costs of disposal.  When the property is acquired, any excess of the loan balance over the estimated net realizable value is charged to the allowance for loan losses. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed.  The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions.  Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties.  In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals.  Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received.
Transfers of Financial Assets
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Income Taxes
The Company files a consolidated federal income tax return.  The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable).
Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements.  These temporary differences will result in differences between income (loss) for tax purposes and income (loss) for financial reporting purposes in future years.  As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision (benefit) for income taxes.  Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not that all or some portion of the potential deferred tax asset will not be realized.
With respect to accounting for uncertainty in incomes taxes, a tax provision is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur.  The amount recognized is the largest amount of tax benefit that is greater than 50% likely to be realized on examination.  For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.  The Company recognizes interest and/or penalties related to income tax matters as income tax expense. The Company is no longer subject to United States federal income tax examination by tax authorities for years ended on or before September 30, 2010.
ESOP
The Bank sponsors a leveraged ESOP that is accounted for in accordance with GAAP.  Accordingly, the debt of the ESOP is recorded as other borrowed funds of the Bank, and the shares pledged as collateral are reported as unearned shares issued to the ESOP in the consolidated balance sheets.  The debt of the ESOP is payable to Timberland Bancorp and is therefore eliminated in the consolidated financial statements.  As shares are released from collateral, compensation expense is recorded equal to the average market price of the shares for the period, and the shares become available for net income per common share calculations.   Dividends paid on unallocated shares reduce the Company’s cash contributions to the ESOP.
Cash and Cash Equivalents and Cash Flows
The Company considers amounts included in the consolidated balance sheets’ captions “Cash and due from financial institutions,” and “Interest-bearing deposits in banks,” all of which mature within ninety days, to be cash equivalents for purposes of reporting cash flows.  Cash flows from loans, deposits, FHLB advances and repurchase agreements are reported net in the accompanying consolidated statements of cash flows.
Interest-bearing deposits in banks as of September 30, 2014 and 2013 included deposits with the FRB of $55,445,000 and $72,955,000, respectively.  The Company also maintains balances in correspondent bank accounts which, at times, may exceed FDIC insurance limits of $250,000.  Management believes that its risk of loss associated with such balances is minimal due to the financial strength of the FRB and the correspondent banks.
Advertising
Costs for advertising and marketing are expensed as incurred.
Stock-Based Compensation
The Company measures compensation cost for all stock-based awards based on the grant-date fair value of the stock-based awards and recognizes compensation cost over the service period of stock-based awards.
The fair value of stock options is determined using the Black-Scholes valuation model.  The fair value of stock grants under the MRDP was equal to the fair value of the shares at the grant date.
The Company’s stock compensation plans are described more fully in Note 15.
Net Income Per Common Share
Basic net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares outstanding during the period, without considering any dilutive items.  Diluted net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for the Timberland Bancorp's common stock during the period.  The 5% dividend and related accretion for the amount of the Company's Series A Preferred Stock outstanding for the respective year was deducted from net income, and the discount on the redemption of Series A Preferred Stock was added to net income in computing net income to common shareholders. Common stock equivalents arise from assumed conversion of outstanding stock options and the outstanding warrant to purchase common stock.  Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing net income per common share.
Related Party Transactions
The Chairman of the Board of the Bank and Timberland Bancorp is a member of the law firm that provides general counsel to the Company.  Legal and other fees paid to this law firm for the years ended September 30, 2014, 2013 and 2012 totaled $179,000, $166,000 and $203,000, respectively.
Recent Accounting Pronouncements
In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exits. The ASU clarifies when it is appropriate for an unrecognized tax benefit, or portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset. ASU 2013-11 is effective for annual periods, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The ASU should be applied prospectively to all unrecognized tax benefits that exist at the effective date; however, retrospective application is also permitted. Adoption of ASU 2013-11 is not expected to have a material impact on the Company's consolidated financial statements.
In January 2014, the FASB issued ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors. The ASU clarifies when an in-substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of the real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate property recognized. ASU 2014-04 is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. The ASU can be adopted using a modified retrospective transition method or a prospective transition method. Adoption of ASU 2014-04 is not expected to have a material impact on the Company's consolidated financial statements.
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The ASU implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 is effective for annual and interim reporting periods beginning after December 15, 2016. Adoption of ASU 2014-09 is not expected to have a material impact on the Company's consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-14, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. The ASU addresses the classification of foreclosed loans that are either fully or partially guaranteed under government programs. ASU 2014-14 clarifies that upon foreclosure of fully or partially guaranteed loans which are guaranteed under government programs and meet certain conditions, the creditor will be required to reclassify the previously existing mortgage loan to a separate other receivable from the guarantor, measured at the amount of the loan balance (principal and interest) that it expects to collect from the guarantor. ASU 2014-14 will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 for public organizations. Adoption of ASU 2014-14 is not expected to have a material impact on the Company's consolidated financial statements.

	The Company has evaluated these securities and has determined that the decline in their value is temporary.  The unrealized losses are primarily due to changes in market interest rates and spreads in the market for mortgage-related products. The fair value of these securities is expected to recover as the securities approach their maturity dates and/or as the pricing spreads narrow on mortgage-related securities.  The Company has the ability and the intent to hold the investments until the market value recovers.  Furthermore, as of September 30, 2014, management does not have the intent to sell any of the securities classified as available for sale where the estimated fair value is below the recorded value and believes that it is more likely than not that the Company will not have to sell such securities before a recovery of cost or recorded value if previously written down.
	In accordance with GAAP, the Company bifurcates OTTI into (1) amounts related to credit losses which are recognized through earnings and (2) amounts related to all other factors which are recognized as a component of other comprehensive income (loss).
To determine the component of the gross OTTI related to credit losses, the Company compared the amortized cost basis of the OTTI security to the present value of its revised expected cash flows, discounted using its pre-impairment yield. The revised expected cash flow estimates for individual securities are based primarily on an analysis of default rates, prepayment speeds and third-party analytic reports.  Significant judgment by management is required in this analysis that includes, but is not limited to, assumptions regarding the collectability of principal and interest, net of related expenses, on the underlying loans.
The following table presents a summary of the significant inputs utilized to measure management’s estimates of the credit loss component on OTTI securities as of September 30, 2014, 2013 and 2012:

	Loan Segment Risk Characteristics
	The Company believes that its loan classes are the same as its loan segments.
	One- To Four-Family Residential Lending:  The Company originates both fixed rate and adjustable rate loans secured by one- to four-family residences.  A portion of the fixed-rate one- to four-family loans are sold in the secondary market for asset/liability management purposes and to generate non-interest income.  The Company’s lending policies generally limit the maximum loan-to-value on one- to four-family loans to 90% of the lesser of the appraised value or the purchase price.  However, the Company usually obtains private mortgage insurance on the portion of the principal amount that exceeds 80% of the appraised value of the property.
	Multi-Family Lending: The Company originates loans secured by multi-family dwelling units (more than four units).  Multi-family lending generally affords the Company an opportunity to receive interest at rates higher than those generally available from one- to four-family residential lending.  However, loans secured by multi-family properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans.  Because payments on loans secured by multi-family properties are often dependent on the successful operation and management of the properties, repayment of such loans may be affected by adverse conditions in the real estate market or economy.  The Company attempts to minimize these risks by scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.
	Commercial Mortgage Lending: The Company originates commercial real estate loans secured by properties such as office buildings, retail/wholesale facilities, motels, restaurants, mini-storage facilities and other commercial properties.  Commercial real estate lending generally affords the Company an opportunity to receive interest at higher rates than those available from one- to four-family residential lending.  However, loans secured by such properties usually are greater in amount, more difficult to evaluate and monitor and, therefore, involve a greater degree of risk than one- to four-family residential mortgage loans.  Because payments on loans secured by commercial properties are often dependent on the successful operation and management of the properties, repayment of these loans may be affected by adverse conditions in the real estate market or economy.  The Company attempts to mitigate these risks by generally limiting the maximum loan-to-value ratio to 80% and scrutinizing the financial condition of the borrower, the quality of the collateral and the management of the property securing the loan.
	Construction Lending:  The Company currently originates the following types of construction loans: custom construction loans, owner/builder construction loans, speculative construction loans (on a very limited basis), commercial real estate construction loans, and multi-family construction loans.  The Company is not currently originating land development loans.
	Construction lending affords the Company the opportunity to achieve higher interest rates and fees with shorter terms to maturity than does its single-family permanent mortgage lending.  Construction lending, however, is generally considered to involve a higher degree of risk than one-to four family residential lending because of the inherent difficulty in estimating both a property’s value at completion of the project and the estimated cost of the project.  The nature of these loans is such that they are generally more difficult to evaluate and monitor.  If the estimated cost of construction proves to be inaccurate, the Company may be required to advance funds beyond the amount originally committed to complete the project.  If the estimate of value upon completion proves to be inaccurate, the Company may be confronted with a project whose value is insufficient to assure full repayment, and the Company may incur a loss.  Projects may also be jeopardized by disagreements between borrowers and builders and by the failure of builders to pay subcontractors.  Loans to construct homes for which no purchaser has been identified carry more risk because the payoff for the loan depends on the builder’s ability to sell the property prior to the time that the construction loan is due.  The Company attempts to mitigate these risks by adhering to its underwriting policies, disbursement procedures, and monitoring practices.
	Construction Lending – Custom and Owner/Builder:  Custom construction loans are made to home builders who, at the time of construction, have a signed contract with a home buyer who has a commitment to purchase the finished home.  Owner/builder construction loans are originated to home owners rather than home builders and are typically refinanced into permanent loans at the completion of construction.
	Construction Lending – Speculative One- To Four-Family: Speculative one-to four-family construction loans are made to home builders and are termed “speculative” because the home builder does not have, at the time of the loan origination, a signed contract with a home buyer who has a commitment for permanent financing with the Company or another lender for the finished home.  The home buyer may be identified either during or after the construction period.  The Company is currently originating speculative one-to four-family construction loans on a very limited basis.
	Construction Lending – Commercial:  Commercial construction loans are originated to construct properties such as office buildings, hotels, retail rental space and mini-storage facilities.
	Construction Lending – Multi-Family:  Multi-family construction loans are originated to construct apartment buildings and condominium projects.
	Construction Lending – Land Development:  The Company historically originated loans to real estate developers for the purpose of developing residential subdivisions.  The Company is not currently originating any land development loans.
	Land Lending: The Company has historically originated loans for the acquisition of land upon which the purchaser can then build or make improvements necessary to build or to sell as improved lots.  Currently, the Company is originating new land loans on a very limited basis.  Loans secured by undeveloped land or improved lots involve greater risks than one- to four-family residential mortgage loans because these loans are more difficult to evaluate.  If the estimate of value proves to be inaccurate, in the event of default or foreclosure, the Company may be confronted with a property value which is insufficient to assure full repayment.  The Company attempts to minimize this risk by generally limiting the maximum loan-to-value ratio on land loans to 75%.
	Consumer Lending – Home Equity and Second Mortgages:   The Company originates home equity lines of credit and second mortgage loans.  Home equity lines of credit and second mortgage loans have a greater credit risk than one- to four-family residential mortgage loans because they are secured by mortgages subordinated to the existing first mortgage on the property, which may or may not be held by the Company.  The Company attempts to mitigate these risks by adhering to its underwriting policies in evaluating the collateral and the credit-worthiness of the borrower.
	Consumer Lending – Other: The Company originates other consumer loans, which include automobile loans, boat loans, motorcycle loans, recreational vehicle loans, savings account loans and unsecured loans.  Other consumer loans generally have shorter terms to maturity than mortgage loans.  Other consumer loans generally involve a greater degree of risk than do residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by rapidly depreciating assets such as automobiles.  In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation.  The Company attempts to mitigate these risks by adhering to its underwriting policies in evaluating the credit-worthiness of the borrower.
	Commercial Business Lending:  The Company originates commercial business loans which are generally secured by business equipment, accounts receivable, inventory or other property.  The Company also generally obtains personal guarantees from the business owners based on a review of personal financial statements.  Commercial business lending generally involves risks that are different from those associated with residential and commercial real estate lending.  Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan to collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default.  Although commercial business loans are often collateralized by equipment, inventory, accounts receivable, or other business assets, the liquidation of collateral in the event of a borrower default is often an insufficient source of repayment, because accounts receivable may be uncollectible and inventories and equipment may be obsolete or of limited use.  Accordingly, the repayment of a commercial business loan depends primarily on the credit-worthiness of the borrower (and any guarantors), while the liquidation of collateral is a secondary and potentially insufficient source of repayment.  The Company attempts to mitigate
	these risks by adhering to its underwriting policies in evaluating the management of the business and the credit-worthiness of the borrowers and the guarantors.

Credit Quality Indicators
The Company uses credit risk grades which reflect the Company’s assessment of a loan’s risk or loss potential.  The Company categorizes loans into risk grade categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors such as the estimated fair value of the collateral.  The Company uses the following definitions for credit risk ratings as part of the on-going monitoring of the credit quality of its loan portfolio:
Pass:  Pass loans are defined as those loans that meet acceptable quality underwriting standards.
Watch:  Watch loans are defined as those loans that still exhibit acceptable quality, but have some concerns that justify greater attention.  If these concerns are not corrected, a potential for further adverse categorization exists.  These concerns could relate to a specific condition peculiar to the borrower or its industry segment or the general economic environment.
Special Mention: Special mention loans are defined as those loans deemed by management to have some potential weaknesses that deserve management’s close attention.  If left uncorrected, these potential weaknesses may result in the deterioration of the payment prospects of the loan.  Assets in this category do not expose the Company to sufficient risk to warrant a substandard classification.
Substandard:  Substandard loans are defined as those loans that are inadequately protected by the current net worth and paying capacity of the obligor, or of the collateral pledged.  Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt.  If the weakness or weaknesses are not corrected, there is the distinct possibility that some loss will be sustained.
Loss:  Loans in this classification are considered uncollectible and of such little value that continuance as an asset is not warranted.  This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not
practical or desirable to defer writing off this basically worthless loan even though partial recovery may be realized in the future.
The following table lists the loan credit risk grades utilized by the Company as credit quality indicators, by portfolio segment, at September 30, 2014 (dollars in thousands). At September 30, 2014 and 2013, there were no loans classified as loss.

	FHLB Advances and Other Borrowings
	The Bank has long- and short-term borrowing lines with the FHLB with total credit on the lines equal to 25% of the Bank’s total assets, limited by available collateral.  Borrowings are considered short-term when the original maturity is less than one year.  The Bank had $45,000,000 of long-term FHLB advances outstanding at September 30, 2014 and 2013.  The long-term borrowings at September 30, 2014 mature at various dates during the 2017 fiscal year and bear interest at rates ranging from 3.69% to 4.34%. Under the Advances, Security and Deposit Agreement entered into with the FHLB ("FHLB Advance Agreement"), virtually all of the Bank’s assets, not otherwise encumbered, are pledged as collateral for advances. A portion of the long-term advances have a putable feature and may be called by the FHLB earlier than the scheduled maturities.
	The Bank also has a variable letter of credit ("VLOC") of up to $5,000,000 with the FHLB for the purpose of collateralizing Washington State public deposits at September 30, 2014. Any amounts advanced by the FHLB on the VLOC will reduce the Bank's available borrowings under the FHLB Advance Agreement.
	The Bank also maintains a short-term borrowing line with the FRB with total credit based on eligible collateral.  At September 30, 2014 the Bank had a borrowing capacity on this line of $39,842,000. The Bank had no outstanding balance on this line at September 30, 2014 and 2013.
	The Bank has a short-term $10,000,000 overnight borrowing line with Pacific Coast Banker's Bank. The borrowing line may be reduced or withdrawn at any time. As of September 30, 2014 and 2013 the Bank did not have any outstanding advances on this borrowing line.

Employee Stock Ownership and 401(k) Plan (KSOP)	'
	Employee Stock Ownership and 401(k) Plan (“KSOP”)
	Effective October 3, 2007, the Bank established the Timberland Bank Employee Stock Ownership and 401(k) Plan (“KSOP”) by combining the existing Timberland Bank Employee Stock Ownership Plan (established in 1997) and the Timberland Bank 401(k) Profit Sharing Plan (established in 1970).  The KSOP is comprised of two components, the ESOP and the 401(k) Plan.  The KSOP benefits employees with at least one year of service who are 21 years of age or older.  It may be funded by Bank contributions in cash or stock for the ESOP and in cash only for the 401(k) profit sharing.  Employee vesting occurs over six years.
	ESOP
	The amount of the annual contribution is discretionary, except that it must be sufficient to enable the ESOP to service its debt.  All dividends received by the ESOP are used to pay debt service. Dividends of $120,000 and $72,000 were used to service the debt during the years ended September 30, 2014 and 2013, respectively. There were no dividends used to service debt for the year ended September 30, 2012.  As the Plan makes each payment of principal and interest, an appropriate percentage of stock is released and allocated annually to eligible employee accounts, in accordance with applicable regulations. As of September 30, 2014, 335,187 ESOP shares had been distributed to participants.
	In January 1998, the ESOP borrowed $7,930,000 from the Company to purchase 1,058,000 shares of common stock of the Company.  The loan is being repaid primarily from the Bank’s contributions to the ESOP and is scheduled to be fully repaid by March 31, 2019. The interest rate on the loan is 8.5%. Interest expense on the ESOP debt was $206,000, $237,000 and
	$266,000 for the years ended September 30, 2014, 2013 and 2012, respectively. The balance of the loan at September 30, 2014 was $2,183,000.
	Shares held by the ESOP as of September 30, 2014, 2013 and 2012 were classified as follows:
		2014	2013	2012
	Unallocated shares	158,702	193,968	229,234
	Shares released for allocation	564,111	592,468	597,641
	Total ESOP shares	722,813	786,436	826,875
	The approximate fair market value of the ESOP’s unallocated shares at September 30, 2014, 2013 and 2012, was $1,673,000, $1,746,000 and $1,375,000, respectively.  Compensation expense recognized under the ESOP for the years ended September 30, 2014, 2013 and 2012 was $242,000, $202,000, and $165,000, respectively.
	401(k)
	Eligible employees may contribute a portion of their wages to the 401(k) part of the plan up to the maximum established by the Internal Revenue Service.  Contributions by the Bank are at the discretion of the Board except for a 3% safe harbor contribution which is mandatory according to the plan document.  Bank contributions totaled $302,000, $289,000 and $283,000 for the years ended September 30, 2014, 2013 and 2012, respectively.

	Under the Company’s stock option plans (1999 Stock Option Plan and 2003 Stock Option Plan), the Company was able to grant options for up to 1,622,500 shares of common stock to employees, officers and directors.  Shares issued may be purchased in the open market or may be issued from authorized and unissued shares. The exercise price of each option equals the fair market value of the Company’s common stock on the date of grant.  Generally, options vest in 20% annual installments on each of the five anniversaries from the date of the grant.  At September 30, 2014, there were no options for common shares available for future grant under the Company's stock option plans.
	Stock option activity for the years ended September 30, 2014, 2013 and 2012 is summarized as follows:
		Number of			Weighted Average
		Shares			Exercise Price
	Outstanding September 30, 2011	137,726			$	9.25

	Options forfeited	(71,546	)		9.87
	Outstanding September 30, 2014	221,400			$	7.49
	The Company uses the Black-Scholes option pricing model to estimate the fair value of stock-based awards with the weighted average assumptions noted in the following table.  The risk-free interest rate is based on the U.S. Treasury rate of a similar term
	as the stock option at the particular grant date.  The expected life is based on historical data, vesting terms, and estimated exercise dates. The expected dividend yield is based on the most recent quarterly dividend on an annualized basis in effect at the time the options were granted, adjusted, if appropriate, for management's expectations regarding future dividends.  At the time the options were granted for the years ended September 30, 2013 and 2012, the Company was under regulatory restrictions prohibiting the payment of dividends. Since management did not know when the Company would be allowed to pay dividends, an expected dividend yield of 0% was used. The expected volatility is based on historical volatility of the Company’s stock price.  There were 76,000 options granted during the year ended September 30, 2012 with an aggregate grant date fair value of $150,000. There were 29,000  options granted during the year ended September 30, 2013 with an aggregate grant date fair value of $69,000. There were 135,000 options granted during the year ended September 30, 2014 with an aggregate grant date fair value of $349,000. The weighted average assumptions for options granted during the years ended September 30, 2014, 2013 and 2012 were as follows:

	At September 30, 2014 there were 177,600 unvested options with an aggregate grant date fair value of $434,000, all of which the Company assumes will vest.  The unvested options had an aggregate intrinsic value of $435,000 at September 30, 2014.  At September 30, 2013 there were 91,000 unvested options with an aggregate grant date fair value of $189,000.

	Stock Grant Plan
	The Company adopted the MRDP in 1998 for the benefit of employees, officers and directors of the Company.  The objective of the MRDP was to retain personnel of experience and ability in key positions by providing them with a proprietary interest in the Company.
	The MRDP allowed for the issuance to participants of up to 529,000 shares of the Company’s common stock.  Awards under the MRDP were made in the form of restricted shares of common stock that are subject to restrictions on the transfer of ownership and are subject to a five-year vesting period.  Compensation expense in the amount of the fair value of the common stock at the date of the grant to the plan participants was recognized over a five-year vesting period, with 20% vesting on each of the five anniversaries from the date of the grant.  At September 30, 2014, there were no shares available for future awards under the MRDP.  There were no MRDP shares granted during the years ended September 30, 2014, 2013 or 2012.

	The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit.  These instruments involve, to varying degrees, elements of credit risk not recognized in the consolidated balance sheets.
	The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments.  The Bank uses the same credit policies in making commitments as it does for on-balance-sheet instruments.
	A summary of the Company’s commitments at September 30, 2014 and 2013 is as follows (dollars in thousands):
		2014		2013
	Undisbursed portion of construction loans in process (see Note 4)	$	29,416	$	18,527
	Undisbursed lines of credit	30,678		25,187
	Commitments to extend credit	18,119		16,399
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract.  Since commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.  The Company evaluates each customer’s credit-worthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the party.  However, such loan to value ratios will subsequently change, based on increases and decreases in the supporting collateral values.  Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, land, and income-producing commercial properties.
	The Company maintains a separate reserve for losses related to unfunded loan commitments.  Management estimates the amount of probable losses related to unfunded loan commitments by applying the loss factors used in the allowance for loan loss methodology to an estimate of the expected amount of funding and applies this adjusted factor to the unused portion of unfunded loan commitments.  The reserve for unfunded loan commitments totaled $192,000 and $165,000 at September 30, 2014 and 2013, respectively.  These amounts are included in other liabilities and accrued expenses in the accompanying consolidated balance sheets.  Increases (decreases) in the reserve for unfunded loan commitments are recorded in non-interest expense in the accompanying consolidated statements of income.
	The Bank has an employee severance compensation plan which expires in 2017, and which provides severance pay benefits to eligible employees in the event of a change in control of Timberland Bancorp or the Bank (as defined in the plan).  In general, all employees with two or more years of service will be eligible to participate in the plan.  Under the plan, in the event of a change in control of Timberland Bancorp or the Bank, eligible employees who are terminated or who terminate employment (but only upon the occurrence of events specified in the plan) within 12 months of the effective date of a change in control would be entitled to a payment based on years of service or officer rank with the Bank.  The maximum payment for any eligible employee would be equal to 24 months of the employee’s current compensation.
	In March 2013, the Bank and the Company entered into employment agreements with the Chief Executive Officer and the Chief Financial Officer. The employment agreements provide for a severance payment and other benefits if the officers are involuntarily terminated following a change in control of the Company or the Bank. The maximum value of the severance benefits under the employment agreements is 2.99 times the officer's average annual compensation during the five-year period prior to the effective date of the change in control.
	Because of the nature of its activities, the Company is subject to various pending and threatened legal actions which arise in the ordinary course of business.  In the opinion of management, liabilities arising from these claims, if any, will not have a material effect on the consolidated financial position of the Company.

	Significant Concentrations of Credit Risk
	Most of the Company’s lending activity is with customers located in the state of Washington and involves real estate.  At September 30, 2014, the Company had $572,083,000 (including $29,416,000 of undisbursed construction loans in process) in loans secured by real estate, which represents 94.2% of total loans and loans held for sale.  The real estate loan portfolio is primarily secured by one- to four-family properties, multi-family properties, undeveloped land, and a variety of commercial real estate property types.  At September 30, 2014, there were no concentrations of real estate loans to a specific industry or secured by a specific collateral type that equaled or exceeded 20% of the Company’s total loan portfolio, other than loans secured by one-to four-family properties.  The ultimate collectability of a substantial portion of the loan portfolio is susceptible to changes in economic and market conditions in the region and the impact of those changes on the real estate market.  The Company typically originates real estate loans with loan-to-value ratios of no greater than 90%.  Collateral and/or guarantees are required for all loans.  The Company also had $35,845,000 in CDs held for investment at September 30, 2014.  The CDs are held with various FDIC insured institutions throughout the U.S., and each CD is below the FDIC insurance limit of $250,000.

Regulatory Capital Requirements [Abstract]	'

	Regulatory Matters
	Timberland Bancorp and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies.  Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements.  Under capital adequacy guidelines of the regulatory framework for prompt corrective action, the Bank must meet specific capital adequacy guidelines that involve quantitative measures of the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices.  The capital classifications of Timberland Bancorp and the Bank are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.
	Federally-insured state-chartered banks are required to maintain minimum levels of regulatory capital.  Under current FDIC regulations, insured state-chartered banks generally must maintain (1) a ratio of Tier 1 leverage capital to total assets of at least 4.0%, (2) a ratio of Tier 1 capital to risk weighted assets of at least 4.0% and (3) a ratio of total capital to risk weighted assets of at least 8.0%.
	The following table compares Timberland Bancorp’s (consolidated) and the Bank’s actual capital amounts at September 30, 2014 and 2013 to their minimum regulatory capital requirements at those dates (dollars in thousands):

	Restrictions on Retained Earnings
	At the time of conversion of the Bank from a Washington-chartered mutual savings bank to a Washington-chartered stock savings bank, the Bank established a liquidation account in an amount equal to its retained earnings of $23,866,000 as of June 30, 1997, the date of the latest statement of financial condition used in the final conversion prospectus.  The liquidation account is maintained for the benefit of eligible account holders who have maintained their deposit accounts in the Bank after conversion.  The liquidation account reduces annually to the extent that eligible account holders have reduced their qualifying deposits as of each anniversary date.  Subsequent increases do not restore an eligible account holder’s interest in the liquidation account.  At September 30, 2014 management estimates the amount of the liquidation account to be $429,000.  In the event of a complete liquidation of the Bank (and only in such an event), eligible depositors who have continued to maintain accounts will be entitled to receive a distribution from the liquidation account before any distribution may be made with respect to common stock.  The Bank may not declare or pay cash dividends if the effect thereof would reduce its regulatory capital below the amount required for the liquidation account.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	Fair Value Measurements
	GAAP requires disclosure of estimated fair values for financial instruments.  Such estimates are subjective in nature, and significant judgment is required regarding the risk characteristics of various financial instruments at a discrete point in time.  Therefore, such estimates could vary significantly if assumptions regarding uncertain factors were to change.  In addition, as the Company normally intends to hold the majority of its financial instruments until maturity, it does not expect to realize many of the estimated amounts disclosed.  The disclosures also do not include estimated fair value amounts for certain items which are not defined as financial instruments but which may have significant value.  The Company does not believe that it would be practicable to estimate a representational fair value for these types of items as of September 30, 2014 and 2013.  Because GAAP excludes certain items from fair value disclosure requirements, any aggregation of the fair value amounts presented would not represent the underlying value of the Company.
	Accounting guidance regarding fair value measurements defines fair value and establishes a framework for measuring fair value in accordance with GAAP.  Fair value is the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date.  The following definitions describe the levels of inputs that may be used to measure fair value:
	Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting
	entity has the ability to access at the measurement date.
	Level 2: Significant observable inputs other than quoted prices included within Level 1, such as
	quoted prices in markets that are not active, and inputs other than quoted prices that are observable or
	can be corroborated by observable market data.
	Level 3: Significant unobservable inputs that reflect a company’s own assumptions about the
	assumptions market participants would use in pricing an asset or liability based on the best information
	available in the circumstances.
	The Company used the following methods and significant assumptions to estimate fair value on a recurring basis:
	Securities Available for Sale
	The estimated fair value of MBS and other investments are based upon the assumptions market participants would use in pricing the security.  Such assumptions include quoted market prices (Level 1), market prices of similar securities or observable inputs (Level 2).
	The following table summarizes the balances of assets and liabilities measured at estimated fair value on a recurring basis at September 30, 2014 (dollars in thousands):

	There were no transfers among Level 1, Level 2 and Level 3 during the year ended September 30, 2013.
	The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP.  These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period.
	The Company uses the following methods and significant assumptions to estimate fair value on a non-recurring basis:
	Impaired Loans: The specific reserve for collateral dependent impaired loans was based on the estimated fair value of the collateral less estimated costs to sell, if applicable.  The estimated fair value of impaired loans is calculated using the collateral value method or on a discounted cash flow basis.  In some cases, adjustments were made to the appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.
	Securities Held to Maturity: The estimated fair value of securities held to maturity are based upon the assumptions market participants would use in pricing the security.  Such assumptions include quoted market prices (Level 1), market prices of similar securities or observable inputs (Level 2) and unobservable inputs such as dealer quotes, discounted cash flows or similar techniques (Level 3).
	OREO and Other Repossessed Assets, net:  The Company’s OREO and other repossessed assets are initially recorded at estimated fair value less estimated costs to sell.  This amount becomes the property’s new basis.  Estimated fair value was generally determined by management based on a number of factors, including third-party appraisals of estimated fair value in an orderly sale.  Estimated costs to sell are based on standard market factors.  The valuation of OREO and other repossessed assets is subject to significant external and internal judgment (Level 3).
	The following table summarizes the balances of assets measured at estimated fair value on a non-recurring basis at September 30, 2014, and the total losses resulting from these estimated fair value adjustments for the year ended September 30, 2014 (dollars in thousands):

The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a non-recurring basis as of September 30, 2014 (dollars in thousands):

Impaired loans					costs
OREO and other repossessed assets	$	9,092	Market approach		Lower of appraised value or	NA
					listing price less selling costs
The following methods and assumptions were used by the Company in estimating fair value of its other financial instruments:
Cash and Cash Equivalents:  The estimated fair value of financial instruments that are short-term or re-price frequently and that have little or no risk are considered to have an estimated fair value equal to the recorded value.
CDs Held for Investment:  The estimated fair value of financial instruments that are short-term or re-price frequently and that have little or no risk are considered to have an estimated fair value equal to the recorded value.
Securities:  See descriptions above.
FHLB Stock:  No ready market exists for this stock, and it has no quoted market value. However, redemption of this stock has historically been at par value. During the year ended September 30, 2014, 2,061 shares of FHLB stock was redeemed from the Company at par value. Accordingly, par value is deemed to be a reasonable estimate of fair value.
Loans Receivable, Net:  At September 30, 2014 the fair value of non-impaired loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers for the same remaining maturities. Prepayments are based on the historical experience of the Bank. Fair values for impaired loans are estimated using the methods described above. At September 30, 2013 the fair value of loans was estimated using a discounted cash flow analysis and comparable market statistics. A discounted cash flow analysis was used to estimate the fair value of loans graded pass. The fair value of loans graded, watch, special mention and substandard was estimated using comparable market statistics that approximated sales of similarly rated loans.
Loans Held for Sale:  The estimated fair value is based on quoted market prices obtained from Freddie Mac.
Accrued Interest:  The recorded amount of accrued interest approximates the estimated fair value.
Deposits:  The estimated fair value of deposits with no stated maturity date is deemed to be the amount payable on demand.  The estimated fair value of fixed maturity certificates of deposit is computed by discounting future cash flows using the rates currently offered by the Bank for deposits of similar remaining maturities.
FHLB Advances:  The estimated fair value of FHLB advances is computed by discounting the future cash flows of the borrowings at a rate which approximates the current offering rate of the borrowings with a comparable remaining life.
Off-Balance-Sheet Instruments:  Since the majority of the Company’s off-balance-sheet instruments consist of variable-rate commitments, the Company has determined that they do not have a distinguishable estimated fair value.
The estimated fair values of financial instruments were as follows as of September 30, 2014 (dollars in thousands):

The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations.  As a result, the estimated fair value of the Company’s financial instruments will change when interest rate levels change, and that change may either be favorable or unfavorable to the Company.  Management attempts to match maturities of assets and liabilities to the extent believed necessary to appropriately manage interest rate risk.  However, borrowers with fixed interest rate obligations are less likely to prepay in a rising interest rate environment and more likely to prepay in a falling interest rate environment.  Conversely, depositors who are receiving fixed interest rates are more likely to withdraw funds before maturity in a rising interest rate environment and less likely to do so in a falling interest rate environment.  Management monitors interest rates and maturities of assets and liabilities, and attempts to manage interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies: Basis of Presentation (Policies)	12 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Timberland Bancorp, Inc. (“Timberland Bancorp”); its wholly owned subsidiary, Timberland Bank (the “Bank”); and the Bank’s wholly owned subsidiary, Timberland Service Corp. (collectively,  “the Company”).  All significant intercompany transactions and balances have been eliminated in consolidation.
Nature of Operations	'
	Nature of Operations
	Timberland Bancorp is a bank holding company which operates primarily through its subsidiary, the Bank.  The Bank was established in 1915 and, through its 22 branches located in Grays Harbor, Pierce, Thurston, Kitsap, King and Lewis counties in Washington State, attracts deposits from the general public, and uses those funds, along with other borrowings, primarily to provide residential real estate, construction, commercial real estate, commercial business and consumer loans to borrowers primarily in western Washington.
Consolidated Financial Statement Presentation	'
	Consolidated Financial Statement Presentation
	The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S.")(“GAAP”) and prevailing practices within the banking industry.
Use of Estimates	'
	The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities, as of the date of the consolidated balance sheet, and the reported amounts of income and expenses during the reporting period.  Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the determination of OTTI in the estimated fair value of MBS, the valuation of MSRs, the valuation of OREO and the valuation of goodwill for potential impairment.
Reclassification Policy	'
	Certain prior year amounts have been reclassified to conform to the 2014 fiscal year presentation with no change to previously reported net income or shareholders’ equity.
Operating Segment Policy	'
	Segment Reporting
	The Company has one reportable operating segment which is defined as community banking in western Washington under the operating name “Timberland Bank.”
U.S. Treasury Department's Capital Purchase Program	'
	Preferred Stock Sold in Troubled Asset Relief Program ("TARP") Capital Purchase Program ("CPP")
	On December 23, 2008, the Company received $16.64 million from the U.S. Treasury Department ("Treasury") as a part of the Treasury's CPP, which was established as part of the TARP. The Company sold 16,641 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A ("Series A Preferred Stock"), with a liquidation value of $1,000 per share and a related warrant to purchase 370,899 shares of the Company's common stock at an exercise price of $6.73 per share (subject to anti-dilution adjustments) at any time through December 23, 2018. The Series A Preferred Stock paid a 5.0% dividend through December 20, 2013, the date of its redemption.
	The proceeds received in connection with the issuance of the Series A Preferred Stock were allocated between the preferred stock and warrant based on their relative fair values on the date of issuance. As a result, the preferred stock's initial recorded value was at a discount from the liquidation value or stated value. The discount from the liquidation value was accreted to the expected/actual redemption date and charged to retained earnings. This accretion was recorded using the level-yield method.
	On November 13, 2012, the Company’s outstanding 16,641 shares of Series A Preferred Stock were sold by the Treasury as part of Treasury's efforts to manage and recover its investments under the TARP. While the sale of this preferred stock to new owners did not result in any proceeds to the Company and did not change the Company’s capital position or accounting for these securities, it did eliminate restrictions put in place by the Treasury on TARP recipients.
	On June 12, 2013, the Treasury sold the warrant to purchase up to 370,899 shares of the Company’s common stock to private investors.  The sale of the warrant to new owners did not result in any proceeds to the Company and did not change the Company's capital position or accounting for the warrant.
	During the year ended September 30, 2013, the Company purchased and retired 4,576 shares of its Series A Preferred Stock for $4.32 million; a $255,000 discount from its liquidation value. The discount from liquidation value on the repurchased shares was recorded as an increase to retained earnings. On December 20, 2013, the Company redeemed the remaining 12,065 shares of its Series A Preferred Stock at the liquidation value of $12.07 million.
MBS and Other Investments	'
	Investment Securities
	Securities are classified upon acquisition as either held to maturity or available for sale.  Securities that the Company has the positive intent and ability to hold to maturity are classified as held to maturity and reflected at amortized cost.  Securities classified as available for sale are reflected at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income (loss), net of tax effects.  Premiums and discounts are amortized to earnings using the interest method over the contractual life of the securities.  Gains and losses on sales of securities are recognized on the trade date and determined using the specific identification method.
	In estimating whether there are any OTTI losses, management considers (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) the financial condition and near term prospects of the issuer, (3) the impact of changes in market interest rates and (4) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for any anticipated recovery in fair value.
	Declines in the fair value of individual securities available for sale that are deemed to be other than temporary are reflected in earnings when identified.  The fair value of the security then becomes the new cost basis.  For individual securities which the Company does not intend to sell and it is not more likely than not that the Company will be required to sell before recovery of its amortized cost basis, the other than temporary decline in the fair value of the security related to: (1) credit loss is recognized in earnings and (2) market or other factors is recognized in other comprehensive income (loss).  Credit loss is recorded if the present value of cash flows is less than the amortized cost.  For individual securities which the Company intends to sell or more likely than not will not recover all of its amortized cost, the OTTI is recognized in earnings equal to the entire difference between the security’s cost basis and its fair value at the consolidated balance sheet date.  For individual securities for which credit loss has been recognized in earnings, interest accruals and amortization and accretion of premiums and discounts are suspended when the credit loss is recognized.  Interest received after accruals have been suspended is recognized on a cash basis.
FHLB Stock	'
	FHLB Stock
	The Company, as a member of the FHLB, is required to maintain an investment in capital stock of the FHLB in an amount equal to the greater of 1% of its outstanding home loans or 5% of advances from the FHLB.  No ready market exists for this stock, and it has no quoted market value. However, redemption of this stock has historically been at par value. The Company's investment in FHLB stock is carried at cost, which approximates fair value.
	The Company evaluates its FHLB stock for impairment as needed. The Company's determination of whether this investment is impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared with the capital stock amount and the length of time any decline has persisted; (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB; (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB; and (4) the liquidity position of the FHLB. The FHLB has recently announced it has entered into an agreement to merge with the Federal Home Loan Bank of Des Moines. Although the agreement is still in process and has not yet been finalized and approved by certain regulatory agencies, management expects that the pending merger will positively affect the Company's recoverability of its investment in FHLB stock and continue to allow the Bank to obtain borrowings consistent with historical FHLB funding practices. Based on its evaluation, the Company determined that there was no impairment of FHLB stock at September 30, 2014 and 2013.
Loans Held For Sale	'
	Loans Held for Sale
	Mortgage loans originated and intended for sale in the secondary market are stated in the aggregate at the lower of cost or estimated fair value.  Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.  Gains or losses on sales of loans are recognized at the time of sale.  The gain or loss is the difference between the net sales proceeds and the recorded value of the loans, including any remaining unamortized deferred loan origination fees.
Loans Receivable	'
	Loans Receivable
	Loans are stated at the amount of unpaid principal, reduced by the undisbursed portion of construction loans in process, deferred loan origination fees and the allowance for loan losses.
Troubled Debt Restructured Loans	'
	Troubled Debt Restructured Loans
	A troubled debt restructured loan is a loan for which the Company, for reasons related to a borrower’s financial difficulties, grants a significant concession to the borrower that the Company would not otherwise consider.
	The loan terms which have been modified or restructured due to a borrower’s financial difficulty, include but are not limited to: a reduction in the stated interest rate; an extension of the maturity at an interest rate below current market rates; a reduction in the face amount of the debt; a reduction in the accrued interest; or re-amortizations, extensions, deferrals and renewals. Troubled debt restructured loans are considered impaired and are individually evaluated for impairment.
Impaired Loans	'
	Impaired Loans
	A loan is generally considered impaired when it is probable that the Company will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement.  When a loan is considered collateral dependent, impairment is measured using the estimated fair value of the underlying collateral, less any prior liens, and when applicable, less estimated selling costs.  For impaired loans that are not collateral dependent, impairment is measured using the present value of expected future cash flows, discounted at the loan’s original effective interest rate.
	The categories of non-accrual loans and impaired loans overlap, although they are not identical.  The Company considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the estimated collateral value, reasons for the delay, payment record, the amount past due and the number of days past due.
Allowance for Loan Losses	'
	Allowance for Loan Losses
	The allowance for loan losses is maintained at a level sufficient to provide for estimated loan losses based on evaluating known and inherent risks in the loan portfolio.  The allowance is provided based upon management's comprehensive analysis of the pertinent factors underlying the quality of the loan portfolio.  These factors include changes in the amount and composition of the loan portfolio, delinquency levels, actual loan loss experience, current economic conditions, and a detailed analysis of individual loans for which full collectability may not be assured.  The detailed analysis includes methods to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment.  The allowance consists of specific and general components.  The specific component relates to loans that are deemed impaired.  For such loans that are classified as impaired, an allowance is established when the discounted cash flows, collateral value less selling costs (if applicable), or observable market price of the impaired loan is lower than the recorded value of that loan.  The general component covers non-classified loans and classified loans that are not evaluated individually for impairment and is based on historical loss experience adjusted for qualitative factors.  The Company's historical loss experience is determined by evaluating the average net charge-offs over the most recent economic cycle, but not to exceed six years. Qualitative factors are determined by loan type and allow management to adjust reserve levels to reflect the current general economic environment and portfolio performance trends including recent charge-off trends.  Allowances are provided based on management’s continuing evaluation of the pertinent factors underlying the quality of the loan portfolio, including changes in the size and composition of the loan portfolio, actual loan loss experience, current economic conditions, collateral values, geographic concentrations, seasoning of the loan portfolio, specific industry conditions, the duration of the current business cycle and regulatory requirements and expectations.  The appropriateness of the allowance for loan losses is estimated based upon these factors and trends identified by management at the time consolidated financial statements are prepared.
	In accordance with GAAP, a loan is considered impaired when it is probable that a creditor will be unable to collect all amounts (principal and interest) due according to the contractual terms of the loan agreement. Smaller balance homogeneous loans, such as residential mortgage loans and consumer loans, may be collectively evaluated for impairment. When a loan has been identified as being impaired, the amount of the impairment is measured by using discounted cash flows, except when, as an alternative, the current estimated fair value of the collateral, reduced by estimated costs to sell (if applicable), or observable market price is used. The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions.  Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate in determining the estimated fair value of particular properties.  In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals.  Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. When the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest and net deferred loan origination fees or costs), impairment is recognized by creating or adjusting an allocation of the allowance for loan losses and uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance.
	A provision for loan losses is charged against operations and is added to the allowance for loan losses based on a quarterly comprehensive analysis of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications and actual loss experience of the loan portfolio.  While management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety.
	The ultimate recovery of all loans is susceptible to future market factors beyond the Company’s control. These factors may result in losses or recoveries differing significantly from those provided in the consolidated financial statements. The Company has experienced a significant decline in valuations for some real estate collateral since October 2008.  If real estate values decline further and as updated appraisals are received on collateral for impaired loans, the Company may need to increase the allowance for loan losses appropriately. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
Interest on Loans and Loan Fees	'
	Interest on Loans and Loan Fees
	Interest on loans is accrued daily based on the principal amount outstanding.  Generally, the accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are past due 90 days as to either principal or interest (based on contractual terms), unless they are well secured and in the process of collection.  In determining whether a borrower may be able to meet payments as they become due, management considers circumstances such as the financial strength of the borrower, the estimated collateral value, reasons for the delays in payments, payment record, the amounts past due and the number of days past due.  All interest accrued but not collected for loans that are placed on non-accrual status or charged off is reversed against interest income.  Subsequent collections on a cash basis are applied proportionately to past due principal and interest, unless collectability of principal is in doubt, in which case all payments are applied to principal.  Loans are returned to accrual status when the loan is deemed current, and the collectability of principal and interest is no longer doubtful, or, in the case of one- to four-family loans, when the loan is less than 90 days delinquent.
	The Company charges fees for originating loans.  These fees, net of certain loan origination costs, are deferred and amortized to income, on the level-yield basis, over the loan term.  If the loan is repaid prior to maturity, the remaining unamortized deferred loan origination fee is recognized in income at the time of repayment.
MSRs	'
	MSRs
	The Company holds rights to service loans that it has originated and sold to the Federal Home Loan Mortgage Corporation (“Freddie Mac”). MSRs are capitalized at estimated fair value when acquired through the origination of loans that are subsequently sold with the servicing rights retained and are amortized to servicing income on loans sold approximately in proportion to and over the period of estimated net servicing income.  The value of MSRs at the date of the sale of loans is estimated based on the discounted present value of expected future cash flows using key assumptions for servicing income and costs and prepayment rates on the underlying loans.  The estimated fair value is periodically evaluated for impairment by comparing actual cash flows and estimated future cash flows from the servicing assets to those estimated at the time the servicing assets were originated.  Fair values are estimated using discounted cash flows based on current market rates of interest.  For purposes of measuring impairment, the MSRs must be stratified by one or more predominant risk characteristics of the underlying loans.  The Company stratifies its capitalized MSRs based on product type and term of the underlying loans.  The amount of impairment recognized is the amount, if any, by which the amortized cost of the MSRs exceeds their fair value.  Impairment, if deemed temporary, is recognized through a valuation allowance to the extent that fair value is less than the recorded amount.
BOLI	'
	BOLI
	BOLI policies are recorded at their cash surrender value less applicable cash surrender charges.  Income from BOLI is recognized when earned.
Goodwill	'
	Goodwill
	Goodwill is initially recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired.  Goodwill is presumed to have an indefinite useful life and is analyzed annually for impairment.  An annual review is performed during the third quarter of each fiscal year, or more frequently if indicators of potential impairment exist, to determine if the recorded goodwill is impaired.  If the estimated fair value of the Company’s sole reporting unit exceeds the recorded value of the reporting unit, goodwill is not considered impaired and no additional analysis is necessary.
	The goodwill impairment test involves a two-step process. Step one estimates the fair value of the reporting unit. If the estimated fair value of the Company's sole reporting unit, the Bank, under step one exceeds the recorded value of the reporting unit, goodwill is not considered impaired and no further analysis is necessary. If the estimated fair value of the Company's sole reporting unit is less than the recorded value, then a step two test test, which calculates the fair value of assets and liabilities to calculate an implied value of goodwill, is performed.
	Step one of the goodwill impairment test estimated the fair value of the reporting unit utilizing a discounted cash flow income approach analysis, a public company market approach analysis, a merger and acquisition market approach analysis and a trading price market approach analysis in order to derive an enterprise value for the Company.
	The discounted cash flow income approach analysis uses a reporting unit's projection of estimated operating results and cash flows and discounts them using a rate that reflects current market conditions. The projection uses management's estimates of economic and market conditions over the projected period including growth rates in loans and deposits, estimates of future expected changes in net interest margins and cash expenditures. Key assumptions used by the Company in its discounted cash flow model (income approach) included an annual growth rate that ranged from 3.00% to 5.10%, an annual deposit growth rate that ranged from 2.80% to 4.00% and a return on assets that ranged from 0.70% to 1.00%. In addition to the above projections of estimated operating results, key assumptions used to determine the fair value estimate under the approach were the discount rate of 13.6% and the residual capitalization rate of 10.6%. The discount rate used was the cost of equity capital. The cost of equity capital was based on the capital asset pricing model ("CAPM"), modified to account for a small stock premium. The small stock premium represents the additional return required by investors for small stocks based on the Stocks, Bonds, Bills and Inflation 2013 Yearbook. Beyond the approximate five-year forecast period, residual free cash flows were estimated to increase at a constant rate into perpetuity. These cash flows were converted to a residual value using an appropriate residual capitalization rate. The residual capitalization rate was equal to the discount rate minus the expected long-term growth rate of cash flows. Based on historical results, the economic climate, the outlook for the industry and management's expectations, a long-term growth rate of 3.0% was estimated.
	The public company market approach analysis estimates the fair value by applying cash flow multiples to the reporting unit's operating performance. The multiples are derived from comparable publicly traded companies with operating and investment characteristics similar to those of the Company. Key assumptions used by the Company included the selection of comparable public companies and performance ratios. In applying the public company analysis, the Company selected eight publicly traded institutions based on similar lines of business, markets, growth prospects, risks and firm size. The performance ratios included price to earnings (last twelve months), price to earnings (current year to date), price to book value, price to tangible book value and price to deposits.
	The merger and acquisition market approach analysis estimates the fair value by using merger and acquisition transactions involving companies that are similar in nature to the Company. Key assumptions used by the Company included the selection of comparable merger and acquisition transactions and valuation ratios to be used. The analysis used banks located in Washington or Oregon that were acquired after January 1, 2012. The valuation ratios from these transactions for price to earnings and price to tangible book value were then used to derive an estimated fair value of the Company.
	The trading price market approach analysis used the closing market price at May 30, 2014 of the Company's common stock, traded on the NASDAQ Global Market to determine the market value of total equity capital.
	A key assumption used by the Company in the public company market approach analysis and the trading price market approach analysis was the application of a control premium. The Company's common stock is thinly traded and therefore management believes the trading price reflects a discount for illiquidity. In addition, the trading price of the Company's common stock reflects a minority interest value. To determine the fair market value of a majority interest in the Company's stock, premiums were calculated and applied to the indicated values. Therefore, a control premium was applied to the results of the public company market approach analysis and the trading price market approach analysis because the initial value conclusion was based on minority interest transactions. Merger and acquisition studies were analyzed to conclude that the difference between the acquisition price and a company's stock price prior to acquisition indicates, in part, the price effect of a controlling interest. Based on the evaluation of merger and acquisition studies, a control premium of 25% was used.
	The Company performed its fiscal year 2014 goodwill impairment test during the quarter ended June 30, 2014 with the assistance of a third-party firm specializing in goodwill impairment valuations for financial institutions. The third-party analysis was conducted as of May 31, 2014 and the step one test concluded that the reporting unit's fair value was more than its recorded value and, therefore, step two of the analysis was not necessary. Accordingly, the recorded value of goodwill as of May 31, 2014 was not impaired.
	A significant amount of judgment is involved in determining if an indicator of goodwill impairment has occurred. Such indicators may include, among others: a significant decline in the expected future cash flows; a sustained significant decline in the Company's stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse assessment or action by a regulator; and unanticipated competition. Key assumptions used in the annual goodwill impairment test are highly judgmental and include: selection of comparable companies, amount of control premium, projected cash flows and discount rate applied to projected cash flows. Any change in these indicators or key assumptions could have a significant negative impact on the Company's financial condition, impact the goodwill impairment analysis or cause the Company to perform a goodwill impairment analysis more frequently than once per year.

Premises and Equipment	'
	Premises and Equipment
	Premises and equipment are recorded at cost.  Depreciation is computed using the straight-line method over the following estimated useful lives:  buildings and improvements - five to 40 years; furniture and equipment - three to seven years; and automobiles - five years.  The cost of maintenance and repairs is charged to expense as incurred.  Gains and losses on dispositions are reflected in earnings.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	Long-lived assets, consisting of premises and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the recorded amount of an asset may not be recoverable.  Recoverability of assets to be held and used is measured by a comparison of the recorded amount of an asset to future net cash flows expected to be generated by the asset.  If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the recorded amount of the assets exceeds the discounted recovery amount or estimated fair value of the assets.  No events or changes in circumstances have occurred during the years ended September 30, 2014 or 2013 that would cause management to evaluate the recoverability of the Company’s long-lived assets.
OREO and Other Repossessed Assets	'
	OREO and Other Repossessed Assets
	OREO and other repossessed assets consist of properties or assets acquired through or in lieu of foreclosure, and are recorded initially at the estimated fair value of the properties less estimated costs of disposal.  When the property is acquired, any excess of the loan balance over the estimated net realizable value is charged to the allowance for loan losses. Costs relating to development and improvement of the properties or assets are capitalized, while costs relating to holding the properties or assets are expensed.  The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions.  Management considers third-party appraisals, as well as independent fair market value assessments from realtors or persons involved in selling real estate, in determining the estimated fair value of particular properties.  In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals.  Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received.
Transfers of Financial Assets	'
	Transfers of Financial Assets
	Transfers of financial assets are accounted for as sales when control over the assets has been surrendered.  Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Income Taxes	'
	Income Taxes
	The Company files a consolidated federal income tax return.  The Bank provides for income taxes separately and remits to (receives from) Timberland Bancorp amounts currently due (receivable).
	Deferred federal income taxes result from temporary differences between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements.  These temporary differences will result in differences between income (loss) for tax purposes and income (loss) for financial reporting purposes in future years.  As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision (benefit) for income taxes.  Valuation allowances are established to reduce the net recorded amount of deferred tax assets if it is determined to be more likely than not that all or some portion of the potential deferred tax asset will not be realized.
	With respect to accounting for uncertainty in incomes taxes, a tax provision is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur.  The amount recognized is the largest amount of tax benefit that is greater than 50% likely to be realized on examination.  For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.  The Company recognizes interest and/or penalties related to income tax matters as income tax expense. The Company is no longer subject to United States federal income tax examination by tax authorities for years ended on or before September 30, 2010.
ESOP	'
	ESOP
	The Bank sponsors a leveraged ESOP that is accounted for in accordance with GAAP.  Accordingly, the debt of the ESOP is recorded as other borrowed funds of the Bank, and the shares pledged as collateral are reported as unearned shares issued to the ESOP in the consolidated balance sheets.  The debt of the ESOP is payable to Timberland Bancorp and is therefore eliminated in the consolidated financial statements.  As shares are released from collateral, compensation expense is recorded equal to the average market price of the shares for the period, and the shares become available for net income per common share calculations.   Dividends paid on unallocated shares reduce the Company’s cash contributions to the ESOP.
Cash and Cash Equivalents and Cash Flows	'
	Cash and Cash Equivalents and Cash Flows
	The Company considers amounts included in the consolidated balance sheets’ captions “Cash and due from financial institutions,” and “Interest-bearing deposits in banks,” all of which mature within ninety days, to be cash equivalents for purposes of reporting cash flows.  Cash flows from loans, deposits, FHLB advances and repurchase agreements are reported net in the accompanying consolidated statements of cash flows.
	Interest-bearing deposits in banks as of September 30, 2014 and 2013 included deposits with the FRB of $55,445,000 and $72,955,000, respectively.  The Company also maintains balances in correspondent bank accounts which, at times, may exceed FDIC insurance limits of $250,000.  Management believes that its risk of loss associated with such balances is minimal due to the financial strength of the FRB and the correspondent banks.
Advertising	'
	Advertising
	Costs for advertising and marketing are expensed as incurred.
Stock-based Compensation	'
	Stock-Based Compensation
	The Company measures compensation cost for all stock-based awards based on the grant-date fair value of the stock-based awards and recognizes compensation cost over the service period of stock-based awards.
	The fair value of stock options is determined using the Black-Scholes valuation model.  The fair value of stock grants under the MRDP was equal to the fair value of the shares at the grant date.
Net Income (Loss) Per Common Share	'
	Net Income Per Common Share
	Basic net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares outstanding during the period, without considering any dilutive items.  Diluted net income per common share is computed by dividing net income to common shareholders by the weighted average number of common shares and common stock equivalents for items that are dilutive, net of shares assumed to be repurchased using the treasury stock method at the average share price for the Timberland Bancorp's common stock during the period.  The 5% dividend and related accretion for the amount of the Company's Series A Preferred Stock outstanding for the respective year was deducted from net income, and the discount on the redemption of Series A Preferred Stock was added to net income in computing net income to common shareholders. Common stock equivalents arise from assumed conversion of outstanding stock options and the outstanding warrant to purchase common stock.  Shares owned by the Bank’s ESOP that have not been allocated are not considered to be outstanding for the purpose of computing net income per common share.
Related Party Transactions	'
	Related Party Transactions
	The Chairman of the Board of the Bank and Timberland Bancorp is a member of the law firm that provides general counsel to the Company.  Legal and other fees paid to this law firm for the years ended September 30, 2014, 2013 and 2012 totaled $179,000, $166,000 and $203,000, respectively.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exits. The ASU clarifies when it is appropriate for an unrecognized tax benefit, or portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction to a deferred tax asset. ASU 2013-11 is effective for annual periods, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The ASU should be applied prospectively to all unrecognized tax benefits that exist at the effective date; however, retrospective application is also permitted. Adoption of ASU 2013-11 is not expected to have a material impact on the Company's consolidated financial statements.
	In January 2014, the FASB issued ASU No. 2014-04, Receivables - Troubled Debt Restructurings by Creditors. The ASU clarifies when an in-substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of the real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate property recognized. ASU 2014-04 is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. The ASU can be adopted using a modified retrospective transition method or a prospective transition method. Adoption of ASU 2014-04 is not expected to have a material impact on the Company's consolidated financial statements.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. The ASU implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 is effective for annual and interim reporting periods beginning after December 15, 2016. Adoption of ASU 2014-09 is not expected to have a material impact on the Company's consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-14, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure. The ASU addresses the classification of foreclosed loans that are either fully or partially guaranteed under government programs. ASU 2014-14 clarifies that upon foreclosure of fully or partially guaranteed loans which are guaranteed under government programs and meet certain conditions, the creditor will be required to reclassify the previously existing mortgage loan to a separate other receivable from the guarantor, measured at the amount of the loan balance (principal and interest) that it expects to collect from the guarantor. ASU 2014-14 will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 for public organizations. Adoption of ASU 2014-14 is not expected to have a material impact on the Company's consolidated financial statements.
