Summary_of_Significant_Account

Summary of Significant Accounting Policies	12 Months Ended
	Sep. 30, 2014
Summary of Significant Accounting Policies	Note 1	Summary of Significant Accounting Policies
	Nature of operations: Home Bancorp Wisconsin, Inc. (the Company) is a Maryland chartered corporation established in June 2013 to become the holding company for Home Savings Bank (the Bank) in connection with the Bank’s mutual-to-stock conversion. The Company’s business activity is the ownership of the Bank’s capital stock and the management of the offering proceeds it retained in connection with the Bank’s conversion. The Company owns 100% of the stock of the Bank. The Bank is a Wisconsin chartered savings bank that provides community banking services to customers in and around Madison, Wisconsin. The Bank accepts deposits and makes loans from our four full-service banking offices, with three offices located in Madison, Wisconsin, and our fourth office located in Stoughton, Wisconsin. The Bank emphasizes permanent and construction loans secured by real estate. Since the Bank’s operations rely heavily on mortgage banking activities, the Bank is exposed to risks relative to changing interest rates and their impact on loan demand. The Bank has a wholly owned subsidiary, Home Agency, Inc., which is no longer active. The Company is subject to competition from other financial institutions and non-financial institutions providing financial products. The Company is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. In the future, the Company may acquire or organize other operating subsidiaries; however, there are no current plans, arrangements, agreements or understandings, written or oral, to do so.
	Principles of consolidation: The consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany balances and transactions have been eliminated in consolidation.
	Jumpstart Our Business Startups Act: The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from completion of the initial stock offering. As an “emerging growth company,” the Company has elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.
	Use of estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, fair values of securities, foreclosed assets, fair value of financial instruments, and valuation of deferred tax assets. Actual results could differ from those estimates.
	Cash and cash equivalents: For purposes of reporting cash flows in the consolidated financial statements, cash and cash equivalents include cash on hand and interest-bearing and non-interest-bearing accounts in other financial institutions, all of which have original maturities of three months or less.
	Other Interest-Bearing Deposits: Other interest-bearing deposits consist of certificates of deposit and are carried at cost.
	Securities: Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity are classified as available for sale and are carried at fair value, with unrealized gains and losses reported in other comprehensive income (loss). Amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the estimated lives of the securities. Gains and losses on the sale of securities are recorded on the trade date and determined using the specific-identification method.
	Declines in fair value of securities that are deemed to be other than temporary, if applicable, are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers the length of time and the extent to which fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
	Loans Held for Sale: Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.
	Mortgage loans held for sale are sold with the mortgage servicing rights released by the Company. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loan sold.
	Loans: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances adjusted for charge-offs and the allowance for loan losses. Interest on loans is accrued and credited to income based on the unpaid principal balance. Loan-origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.
	The accrual of interest on loans is discontinued when, in the opinion of management, there is an indication the borrower may be unable to make payments as they become due. When loans are placed on nonaccrual or charged off, all unpaid accrued interest is reversed against interest income. The interest on these loans is subsequently accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
	Allowance for Loan Losses: The allowance for loan losses is maintained at the level considered adequate by management to provide for losses that are probable. The allowance for loan losses is established through a provision for loan losses charged to expense as losses are estimated to have occurred. Loan losses are charged against the allowance when management believes that the collectibility of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance.
	Management regularly evaluates the allowance for loan losses using the Company’s past loan loss experience, known and inherent risks in the portfolio, composition of the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic conditions, and other relevant factors. This evaluation is inherently subjective since it requires material estimates that may be susceptible to significant change.
	A loan is impaired when, based on current information, it is probable that the Company will not collect all amounts due in accordance with the contractual terms of the loan agreement. Management determines whether a loan is impaired on a case-by-case basis, taking into consideration the payment status, collateral value, length and reason of any payment delays, the borrower’s prior payment record, and any other relevant factors. Large groups of smaller-balance homogeneous loans, such as residential mortgage and consumer loans, are collectively evaluated in the allowance for loan losses analysis and are not subject to impairment analysis unless such loans have been subject to a restructuring agreement. Specific allowances for impaired loans are based on discounted cash flows of expected future payments using the loan’s initial effective interest rate or the fair value of the collateral if the loan is collateral dependent.
	In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require additions to the allowance for loan losses based on their judgments of collectability.
	Troubled debt restructurings: Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants a “concession” to the borrower that they would no otherwise consider. These concessions include a modification of terms such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment. Troubled debt restructurings are considered impaired loans.
	Foreclosed Assets: Assets acquired through or in lieu of loan foreclosure are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Costs relating to the development and improvement of property are capitalized; holding costs are charged to expense. Subsequent to foreclosure, valuations are periodically performed by management, and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets.
	Premises and Equipment: Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets.
	Federal Home Loan Bank (FHLB) Stock: FHLB stock is carried at cost. The Company is required to hold the stock as a member of FHLB, and transfer of the stock is substantially restricted. The stock is pledged as collateral for outstanding FHLB advances. FHLB stock is evaluated for impairment on an annual basis, and no impairment has been identified as a result of these reviews.
	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.
	Rate Lock Commitments: The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in derivative assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements and, for fixed rate commitments, also considers the value of the servicing release premium and the difference between current levels of interest rates and the committed rates.
	Income Taxes: Deferred tax assets and liabilities have been determined using the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities as measured by the current enacted tax rates that will be in effect when these differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Provision (credit) for deferred taxes is the result of changes in the deferred tax assets and liabilities.
	The Company may also recognize a liability for unrecognized tax benefits from uncertain tax positions. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the consolidated financial statements. Interest and penalties related to unrecognized tax benefits are classified as income taxes.
	Employee Stock Ownership Plan: The Company has an employee stock ownership plan (ESOP) covering substantially all employees. The cost of shares issued to the ESOP, but not yet allocated to participants, is presented in the consolidated balance sheet as a reduction of stockholders’ equity. Compensation expense is recorded based on the market price of the shares as they are committed to be released for allocation to participant accounts.
	Advertising: Advertising costs are expensed as incurred.
	Off-Balance-Sheet Financial Instruments: In the ordinary course of business, the Company has entered into off-balance-sheet financial instruments including commitments to extend credit, unfunded commitments under lines of credit, and standby letters of credit. Such financial instruments are recorded in the consolidated financial statements when they become payable.
	Segment Reporting: The Company views the Bank as one reporting segment, therefore, separate reporting of financial segment information is not considered necessary.
	Reclassifications: Certain reclassifications have been made to the 2013 consolidated financial statements to conform to the 2014 classifications.
	Subsequent Events: Management has reviewed the Company’s operations for potential disclosure or financial statement impacts related to events occurring after September 30, 2014, but prior to the release of these consolidated financial statements. Based on the results of this review, no subsequent event disclosure or financial statement impacts to these consolidated financial statements are required as of December 23, 2014.
	Recent accounting pronouncements: In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. ASU No. 2013-04 provides recognition, measurement, and disclosure guidance for certain obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. This guidance is effective for annual and interim periods beginning after December 15, 2014. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In January 2014, FASB issued Accounting Standards Update (ASU) No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The primary purpose of this new guidance is to clarify, for residential mortgage loans, when an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a residential mortgage loan. This guidance is effective for annual and interim periods beginning after December 15, 2014. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In January 2014, FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The primary purpose of this new guidance is to revise the conditions that an entity must meet to elect to use the effective yield method when accounting for qualified affordable housing project investments. Per current accounting guidance, an entity that invests in a qualified affordable housing project may elect to account tor that investment using the effective yield method, current accounting guidance requires that the investments be accounted for under either the equity method or the cost method. Certain existing conditions required to be met to use the effective yield method are restrictive and thus prevent many such investments from qualifying for the use of the effective yield method.
	The ASU replaces the effective yield method with the proportional amortization method and modifies the conditions that an entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. It the modified conditions are met, the ASU permits an entity to use the proportional amortization method to amortize the initial cost of the investment in proportion to the amount of tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. Additionally, the ASU requires new disclosures about all investments in qualified affordable housing projects irrespective of the method used to account for the investments. This guidance is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Under the amended guidance, 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. This guidance is effective for annual and interim periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements, but significant disclosures to the Notes thereto will be required.
	In June 2014, FASB issued ASU No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financing, and Disclosures. The amendments in this guidance require repurchase-to-maturity transactions to be accounted for as secured borrowings. This guidance is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.

Earnings Per Share	Note 2	Earnings Per Share
	Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period, including allocated and committed-to-be-released ESOP shares, during the applicable period. Diluted earnings per share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method.
	The following table presents a reconciliation of the number of shares used in the calculation of basic and diluted earnings per common share:

	At September 30, 2014, eight debt securities have unrealized losses with aggregate depreciation of less than 1% from the Company’s amortized cost basis. These unrealized losses relate principally to the increase in interest rates and are not caused by changes in the financial condition of the issuer, the quality of any underlying assets, or applicable credit enhancements. In analyzing whether unrealized losses on debt securities are other than temporary, management considers whether the securities are issued by a government body or agency, whether a rating agency has downgraded the securities, industry analysts’ reports, the financial condition and performance of the issuer, and the quality of any underlying assets or credit enhancements. Since management has the ability to hold debt securities for the foreseeable future, no declines are deemed to be other than temporary.
	The following is a summary of amortized cost and estimated fair value of debt securities by contractual maturity as of September 30, 2014. Contractual maturities will differ from expected maturities because borrowers may have the right to call or prepay obligations without penalties.

The Company regularly evaluates various attributes of loans to determine the appropriateness of the allowance for loan losses. The credit quality indicators monitored differ depending on the class of loan.
Commercial loans are generally evaluated using the following internally prepared ratings:
“Pass” ratings are assigned to loans with adequate collateral and debt service ability such that collectibility of the contractual loan payments is highly probable.
“Special mention/watch” ratings are assigned to loans where management has some concern that the collateral or debt service ability may not be adequate, though the collectibility of the contractual loan payments is still probable.
“Substandard” ratings are assigned to loans that do not have adequate collateral and/or debt service ability such that collectibility of the contractual loan payments is no longer probable.
“Doubtful” ratings are assigned to loans that do not have adequate collateral and/or debt service ability, and collectibility of the contractual loan payments is unlikely.
Residential real estate and consumer loans are generally evaluated based on whether or not the loan is performing according to the contractual terms of the loan.

When, for economic or legal reasons related to the borrower’s financial difficulties, the Company grants a concession to the borrower that the Company would not otherwise consider, the modified loan is classified as a troubled debt restructuring. Loan modifications may consist of forgiveness of interest and/or principal, a reduction of the interest rate, interest-only payments for a period of time, and/or extending amortization terms. No new troubled debt restructurings were entered into during the year ended September 30, 2014.
During the year ended and as of September 30, 2013, there were three new troubled debt restructurings: first, two commercial and industrial loans for one borrower, totaling $105; second, a commercial real estate loan of $60. There were no changes in the principal balance as a result of these modifications.

FHLB provides both fixed and floating rate advances. Floating rates are tied to short-term market rates of interest, such as London InterBank Offered Rate (LIBOR), federal funds, or treasury bill rates. Advances with call provisions permit the FHLB to request payment beginning on the call date and quarterly thereafter. FHLB advances are subject to a prepayment penalty if they are repaid prior to maturity.

	Net deferred tax asset		$	—		$	—
	The Company has federal and state net operating loss carryforwards totaling approximately $4,313 and $4,818, respectively, that may be applied against future federal and state taxable income and begin to expire in 2030. The Company has available alternative minimum tax credit carryforwards for federal tax purposes of approximately $64, which may be used indefinitely to reduce regular federal income taxes.
	Deferred tax assets are deferred tax consequences attributable to deductible temporary differences and carryforwards. After the deferred tax asset has been measured using the applicable enacted tax rate and provisions of the enacted tax law, it is then necessary to assess the need for a valuation allowance. A valuation allowance is needed when, based on the weight of the available evidence, it is more likely than not that some portion of the deferred tax asset will not be realized. As required by generally accepted accounting principles, available evidence is weighted heavily on cumulative losses with less weight placed on future projected profitability. Realization of the deferred tax asset is dependent on whether there will be sufficient future taxable income of the appropriate character in the period during which deductible temporary differences reverse or within the carryforward periods available under tax law. Based on the available evidence, valuation allowances of $2,551 and $2,008 were recognized as of September 30, 2014 and 2013, respectively while $3 and $1 were the portion of the changes in net deferred tax asset related to changes that flowed through comprehensive loss, as of September 30, 2014 and 2013, respectively.
	With few exceptions, the Company is no longer subject to federal or state examinations by tax authorities for years before 2009.

Regulatory Matters	Note 13	Regulatory Matters
	The Bank is subject to various regulatory capital requirements administered by federal and state 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 Bank’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier I capital to risk-weighted assets and of Tier I capital to average assets.
	As of September 30, 2014, the Bank was well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table. There are no conditions or events since September 30, 2014, that management believes have changed the Bank’s category.
	On June 6, 2012, the Bank entered into a memorandum of understanding (“Memorandum”) with the Federal Deposit Insurance Corporation (FDIC) and the State of Wisconsin Department of Financial Institutions (WDFI). The Memorandum required, among other things, that the Bank maintain a Tier 1 capital level equal to 8.0% of total average assets and a total risk-based capital level equal to 12.0% of risk-weighted assets. On September 29, 2014, the Memorandum was terminated by the FDIC and the WDFI.
	The Bank’s actual capital amounts and ratios as of September 30 are presented in the following table:
			Actual							For Capital								To Be Well Capitalized

Commitments, Contingencies, and Credit Risk	12 Months Ended
	Sep. 30, 2014
Commitments, Contingencies, and Credit Risk	Note 14	Commitments, Contingencies, and Credit Risk
	Credit Risk
	The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.
	The Company’s exposure to credit loss is represented by the contractual, or notional, amount of these commitments. The Company follows the same credit policies in making commitments as it does for on-balance-sheet instruments. Since some of the commitments are expected to expire without being drawn upon and some of the commitments may not be drawn upon to the total extent of the commitment, the notional amount of these commitments does not necessarily represent future cash requirements.
	The following commitments were outstanding at September 30:
			Notional Amount
			2014		2013
	Commitments to extend credit		$	902	$	24
	Unused lines of credit and credit card lines			11,682		11,931
	Undisbursed portion of loan proceeds			128		357
	Standby letters of credit			651		641
	Commitments to extend credit (including undisbursed loans under rate lock commitments) are agreements to lend to a customer as long as there is no violation of any condition established in the contract. All of these commitments are at fixed rates. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The amount of collateral obtained upon extension of credit is based on management’s credit evaluation of the customer.
	Unused commitments under lines of credit and credit card lines are commitments for possible future extensions of credit to existing customers. These lines of credit may or may not require collateral and may or may not contain a specific maturity date.
	The undisbursed portion of loan proceeds represents undrawn amounts under construction loans. These loans are generally secured by real estate and generally have a specific maturity date.
	Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. Generally all standby letters of credit issued have expiration dates within one year. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company generally holds collateral supporting these commitments. Standby letters of credit are not reflected in the consolidated financial statements, since recording the fair value of these guarantees would not have a significant impact on the consolidated financial statements.
	Legal Contingencies
	Various legal claims arise from time to time in the normal course of business. In the opinion of management, any liability resulting from such proceedings would not have a material impact on the consolidated financial statements.
	Concentration of Credit Risk
	The majority of the Company’s loans and commitments have been granted to customers in the Company’s market area. The concentrations of credit by type are set forth in Note 4. The ability of the Company’s debtors to honor their contracts is dependent on the real estate and general economic conditions in this area. Management believes the diversity of the local economy will prevent significant losses in the event of an economic downturn.

Fair_Value_Measurements

Fair Value Measurements	12 Months Ended
	Sep. 30, 2014
Fair Value Measurements	Note 15	Fair Value Measurements
	Accounting standards describe three levels of inputs that may be used to measure fair value (the fair value hierarchy). The level of an asset or liability within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement of that asset or liability.
	Following is a brief description of each level of the fair value hierarchy:
	Level 1 - Fair value measurement is based on quoted prices for identical assets or liabilities in active markets.
	Level 2 - Fair value measurement is based on: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; or (3) valuation models and methodologies for which all significant assumptions are or can be corroborated by observable market data.
	Level 3 - Fair value measurement is based on valuation models and methodologies that incorporate at least one significant assumption that cannot be corroborated by observable market data. Level 3 measurements reflect the Company’s estimates about assumptions market participants would use in measuring fair value of the asset or liability.
	Some assets and liabilities, such as securities available for sale, are measured at fair value on a recurring basis under accounting principles generally accepted in the United States. Other assets and liabilities, such as impaired loans, may be measured at fair value on a nonrecurring basis.
	Following is a description of the valuation methodology used for each asset measured at fair value on a recurring or nonrecurring basis, as well as the classification of the asset within the fair value hierarchy.
	Securities available for sale - Securities available for sale may be classified as Level 1 or Level 2 measurements within the fair value hierarchy. Level 1 securities include equity securities traded on a national exchange. The fair value measurement of a Level 1 security is based on the quoted price of the security. Level 2 securities include U.S. government and agency securities, obligations of states and political subdivisions, corporate debt securities, and mortgage-related securities. The fair value measurement of a Level 2 security is obtained from an independent pricing service and is based on recent sales of similar securities and other observable market data.
	Loans - Loans are not measured at fair value on a recurring basis. However, loans considered to be impaired may be measured at fair value on a nonrecurring basis. The fair value measurement of an impaired loan that is collateral dependent is based on the fair value of the underlying collateral. All other impaired loan measurements are based on the present value of expected future cash flows discounted at the applicable effective interest rate and, thus, are not fair value measurements. Fair value measurements of underlying collateral that utilize observable market data, such as independent appraisals reflecting recent comparable sales, are considered Level 2 measurements. Other fair value measurements that incorporate estimated assumptions market participants would use to measure fair value are considered Level 3 measurements.
	Foreclosed assets - Real estate and other property acquired through or in lieu of loan foreclosure are not measured at fair value on a recurring basis. However, foreclosed assets are initially measured at fair value (less estimated costs to sell) when they are acquired and may also be measured at fair value (less estimated costs to sell) if they become subsequently impaired. The fair value measurement for each asset may be obtained from an independent firm or prepared internally. Fair value measurements obtained from independent firms are generally based on sales of comparable assets and other observable market data and are considered Level 2 measurements. Fair value measurements prepared internally are based on observable market data but include significant unobservable data and are therefore considered Level 3 measurements.

	Loans with a carrying amount of $825 and $818 were considered impaired and were written down to their estimated fair value of $593 and $572 as of September 30, 2014 and 2013, respectively. As a result, the Company recognized a specific valuation allowance against these impaired loans totaling $232 and $246 during the years ended September 30, 2014 and 2013, respectively. The loans were valued based on the value of the underlying collateral, adjusted for selling costs. The fair value of collateral is determined based on appraisals, broker price opinions, or automated valuation models. In some cases, adjustments were made to these values due to various factors including age of the appraisal, age of the comparable and other known changes in the market and in the collateral. When significant adjustments were based on unobservable inputs, the resulting fair value measurement has been categorized as a Level 3 measurement.
	At September 30, 2014 and 2013, foreclosed assets with a fair value less estimated costs to sell of $775 and $1,006, respectively, were acquired through or in lieu of foreclosure. The fair value of foreclosed assets is determined based on appraisals, broker price opinions, or automated valuation models. In some cases, adjustments were made to these values due to various factors including age of the appraisal, age of the comparable and other known changes in the market and in the collateral. When significant adjustments were based on unobservable inputs, the resulting fair value measurement has been categorized as a Level 3 measurement.
	The Company estimates fair value of all financial instruments regardless of whether such instruments are measured at fair value. The following methods and assumptions were used by the Company to estimate fair value of financial instruments not previously discussed.
	Cash and cash equivalents - Fair value approximates the carrying value.
	Other interest-bearing deposits - Fair value is estimated using discounted cash flow analyses based on current rates for similar types of deposits.
	Securities held to maturity - Fair value is based on quoted market prices where available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities.
	Loans held for sale - Fair value is based on commitments on hand from investors or prevailing market prices.
	Loans - Fair value of variable rate loans that reprice frequently is based on carrying values. Fair value of other loans is estimated by discounting future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings. Fair value of impaired and other nonperforming loans is estimated using discounted expected future cash flows or the fair value of underlying collateral, if applicable.
	Federal Home Loan Bank stock - Fair value is the redeemable (carrying) value based on the redemption provisions of the Federal Home Loan Bank.
	Accrued interest receivable and payable - Fair value approximates the carrying value.
	Cash value of life insurance - Fair value is based on reported values of the assets.
	Deposits and advance payments by borrowers for taxes and insurance - Fair value of deposits with no stated maturity, such as demand deposits, savings, and money market accounts, including advance payments by borrowers for taxes and insurance, by definition, is the amount payable on demand on the reporting date. Fair value of fixed rate time deposits is estimated using discounted cash flows applying interest rates currently being offered on similar time deposits.
	Federal funds purchased - Fair value approximates carrying value.
	Borrowed funds - Fair value of fixed rate, fixed term borrowings is estimated by discounting future cash flows using the current rates at which similar borrowings would be made. Fair value of borrowings with variable rates or maturing within 90 days approximates the carrying value of these borrowings.
	Off-balance-sheet instruments - Fair value is based on quoted market prices of similar financial instruments where available. If a quoted market price is not available, fair value is based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the counterparty’s credit standing. Since the estimated fair value of off-balance-sheet instruments is not material, no amounts are presented in the following schedule.

Limitations - The fair value of a financial instrument is the current amount that would be exchanged between market participants, other than in a forced liquidation. Fair value is best determined based on quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Consequently, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company.
Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters that could affect the estimates. Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business. Deposits with no stated maturities are defined as having a fair value equivalent to the amount payable on demand. This prohibits adjusting fair value derived from retaining those deposits for an expected future period of time. This component, commonly referred to as a deposit base intangible, is neither considered in the above amounts, nor is it recorded as an intangible asset on the consolidated balance sheets. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Employee_Stock_Ownership_Plan

Employee Stock Ownership Plan	12 Months Ended
	Sep. 30, 2014
Employee Stock Ownership Plan	Note 16	Employee Stock Ownership Plan
	The Company adopted an employee stock ownership plan (“ESOP”) for the benefit of substantially all employees effective January 1, 2014. On April 23, 2014, the date of conversion, the ESOP borrowed $719 from the Company and used those funds to acquire 71,935 shares of the Company’s stock at a price of $10.00 per share. The Company accounts for its ESOP in accordance with ASC 718-40. Accordingly, because the debt is intercompany, it is eliminated in consolidation for presentation in these financial statements. The shares pledged as collateral are reported as unearned ESOP shares in the balance sheet.
	Shares issued to the ESOP are allocated to ESOP participants based on principal and interest repayment made by the ESOP on the loan. The loan is secured by shares purchased with the loan proceeds and will be repaid by the ESOP with funds from the Bank’s discretionary contributions to the ESOP and earnings on ESOP assets.
	The $719 loan for the ESOP purchase was borrowed from the Company and requires annual payments to be made by the ESOP of approximately $41, including principal and interest at a rate of 3.25%.
	As shares are released from collateral, the Company will report compensation expense equal to the current market price of the shares and the shares will become outstanding for earnings-per-shares (EPS) computations. During 2014, 2,158 shares, with an average fair value of $9.11 per share, were committed to be released resulting in ESOP compensation expense of $19 for the year ended September 30, 2014. No ESOP compensation expense was recorded for the year ended September 30, 2013. The ESOP shares as of September 30 were as follows:

Plan of Conversion and Change in Corporate Form	Note 17	Plan of Conversion and Change in Corporate Form
	In June 2013, the Board of Directors of the Bank adopted a plan of conversion (the “Plan”) to convert from the mutual form of organization to the capital stock form of organization. A new Maryland-chartered corporation, Home Bancorp Wisconsin, Inc., was formed on May 31, 2013, to become the stock bank holding company of the Bank upon consummation of the conversion. The Company filed a registration statement with the U.S. Securities and Exchange Commission which was declared effective on February 11, 2014. The Plan was approved by the affirmative vote of a majority of the total votes eligible to be cast by the voting members of Home Savings Bank at a special meeting held on March 25, 2014. In the conversion the Bank became a wholly owned subsidiary of the Company, and the Company issued and sold shares of its capital stock to eligible members of the Bank and to the public. The conversion was completed with the sale of 899,190 shares on April 23, 2014. The costs of reorganization and issuing the common stock have been deducted from the sales proceeds of the offering. The Company recognized $1.6 million in reorganization and stock issuance costs as of September 30, 2014. The Company’s Board of Directors adopted an employee stock ownership plan (ESOP) which subscribed to 8% of the common stock sold in the offering.
	The conversion was accounted for as a change in corporate form, with the historic basis of the Bank’s assets, liabilities, and equity unchanged as a result.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2014
Nature of Operations	Nature of operations: Home Bancorp Wisconsin, Inc. (the Company) is a Maryland chartered corporation established in June 2013 to become the holding company for Home Savings Bank (the Bank) in connection with the Bank’s mutual-to-stock conversion. The Company’s business activity is the ownership of the Bank’s capital stock and the management of the offering proceeds it retained in connection with the Bank’s conversion. The Company owns 100% of the stock of the Bank. The Bank is a Wisconsin chartered savings bank that provides community banking services to customers in and around Madison, Wisconsin. The Bank accepts deposits and makes loans from our four full-service banking offices, with three offices located in Madison, Wisconsin, and our fourth office located in Stoughton, Wisconsin. The Bank emphasizes permanent and construction loans secured by real estate. Since the Bank’s operations rely heavily on mortgage banking activities, the Bank is exposed to risks relative to changing interest rates and their impact on loan demand. The Bank has a wholly owned subsidiary, Home Agency, Inc., which is no longer active. The Company is subject to competition from other financial institutions and non-financial institutions providing financial products. The Company is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. In the future, the Company may acquire or organize other operating subsidiaries; however, there are no current plans, arrangements, agreements or understandings, written or oral, to do so.
Principles of Consolidation	Principles of consolidation: The consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany balances and transactions have been eliminated in consolidation.
Jumpstart Our Business Startups Act	Jumpstart Our Business Startups Act: The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from completion of the initial stock offering. As an “emerging growth company,” the Company has elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.
Use of Estimates	Use of estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, fair values of securities, foreclosed assets, fair value of financial instruments, and valuation of deferred tax assets. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and cash equivalents: For purposes of reporting cash flows in the consolidated financial statements, cash and cash equivalents include cash on hand and interest-bearing and non-interest-bearing accounts in other financial institutions, all of which have original maturities of three months or less.
Other Interest-Bearing Deposits	Other Interest-Bearing Deposits: Other interest-bearing deposits consist of certificates of deposit and are carried at cost.
Securities	Securities: Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity are classified as available for sale and are carried at fair value, with unrealized gains and losses reported in other comprehensive income (loss). Amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the estimated lives of the securities. Gains and losses on the sale of securities are recorded on the trade date and determined using the specific-identification method.
	Declines in fair value of securities that are deemed to be other than temporary, if applicable, are reflected in earnings as realized losses. In estimating other-than-temporary impairment losses, management considers the length of time and the extent to which fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
Loans Held for Sale	Loans Held for Sale: Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income.
	Mortgage loans held for sale are sold with the mortgage servicing rights released by the Company. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loan sold.
Loans	Loans: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances adjusted for charge-offs and the allowance for loan losses. Interest on loans is accrued and credited to income based on the unpaid principal balance. Loan-origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method.
	The accrual of interest on loans is discontinued when, in the opinion of management, there is an indication the borrower may be unable to make payments as they become due. When loans are placed on nonaccrual or charged off, all unpaid accrued interest is reversed against interest income. The interest on these loans is subsequently accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses: The allowance for loan losses is maintained at the level considered adequate by management to provide for losses that are probable. The allowance for loan losses is established through a provision for loan losses charged to expense as losses are estimated to have occurred. Loan losses are charged against the allowance when management believes that the collectibility of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance.
	Management regularly evaluates the allowance for loan losses using the Company’s past loan loss experience, known and inherent risks in the portfolio, composition of the portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, current economic conditions, and other relevant factors. This evaluation is inherently subjective since it requires material estimates that may be susceptible to significant change.
	A loan is impaired when, based on current information, it is probable that the Company will not collect all amounts due in accordance with the contractual terms of the loan agreement. Management determines whether a loan is impaired on a case-by-case basis, taking into consideration the payment status, collateral value, length and reason of any payment delays, the borrower’s prior payment record, and any other relevant factors. Large groups of smaller-balance homogeneous loans, such as residential mortgage and consumer loans, are collectively evaluated in the allowance for loan losses analysis and are not subject to impairment analysis unless such loans have been subject to a restructuring agreement. Specific allowances for impaired loans are based on discounted cash flows of expected future payments using the loan’s initial effective interest rate or the fair value of the collateral if the loan is collateral dependent.
	In addition, various regulatory agencies periodically review the allowance for loan losses. These agencies may require additions to the allowance for loan losses based on their judgments of collectability.
Troubled debt restructurings	Troubled debt restructurings: Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants a “concession” to the borrower that they would no otherwise consider. These concessions include a modification of terms such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment. Troubled debt restructurings are considered impaired loans.
Foreclosed Assets	Foreclosed Assets: Assets acquired through or in lieu of loan foreclosure are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Costs relating to the development and improvement of property are capitalized; holding costs are charged to expense. Subsequent to foreclosure, valuations are periodically performed by management, and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets.
Premises and Equipment	Premises and Equipment: Land is carried at cost. Buildings and equipment are stated at cost less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets.
Federal Home Loan Bank (FHLB) Stock	Federal Home Loan Bank (FHLB) Stock: FHLB stock is carried at cost. The Company is required to hold the stock as a member of FHLB, and transfer of the stock is substantially restricted. The stock is pledged as collateral for outstanding FHLB advances. FHLB stock is evaluated for impairment on an annual basis, and no impairment has been identified as a result of these reviews.
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.
Rate Lock Commitments	Rate Lock Commitments: The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in derivative assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements and, for fixed rate commitments, also considers the value of the servicing release premium and the difference between current levels of interest rates and the committed rates.
Income Taxes	Income Taxes: Deferred tax assets and liabilities have been determined using the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities as measured by the current enacted tax rates that will be in effect when these differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Provision (credit) for deferred taxes is the result of changes in the deferred tax assets and liabilities.
	The Company may also recognize a liability for unrecognized tax benefits from uncertain tax positions. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the consolidated financial statements. Interest and penalties related to unrecognized tax benefits are classified as income taxes.
Employee Stock Ownership Plan	Employee Stock Ownership Plan: The Company has an employee stock ownership plan (ESOP) covering substantially all employees. The cost of shares issued to the ESOP, but not yet allocated to participants, is presented in the consolidated balance sheet as a reduction of stockholders’ equity. Compensation expense is recorded based on the market price of the shares as they are committed to be released for allocation to participant accounts.
Advertising	Advertising: Advertising costs are expensed as incurred.
Off-Balance-Sheet Financial Instruments	Off-Balance-Sheet Financial Instruments: In the ordinary course of business, the Company has entered into off-balance-sheet financial instruments including commitments to extend credit, unfunded commitments under lines of credit, and standby letters of credit. Such financial instruments are recorded in the consolidated financial statements when they become payable.
Segment Reporting	Segment Reporting: The Company views the Bank as one reporting segment, therefore, separate reporting of financial segment information is not considered necessary.
Reclassifications	Reclassifications: Certain reclassifications have been made to the 2013 consolidated financial statements to conform to the 2014 classifications.
Subsequent Events	Subsequent Events: Management has reviewed the Company’s operations for potential disclosure or financial statement impacts related to events occurring after September 30, 2014, but prior to the release of these consolidated financial statements. Based on the results of this review, no subsequent event disclosure or financial statement impacts to these consolidated financial statements are required as of December 23, 2014.
Recent accounting pronouncements	Recent accounting pronouncements: In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date. ASU No. 2013-04 provides recognition, measurement, and disclosure guidance for certain obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. This guidance is effective for annual and interim periods beginning after December 15, 2014. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In January 2014, FASB issued Accounting Standards Update (ASU) No. 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The primary purpose of this new guidance is to clarify, for residential mortgage loans, when an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a residential mortgage loan. This guidance is effective for annual and interim periods beginning after December 15, 2014. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In January 2014, FASB issued ASU No. 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. The primary purpose of this new guidance is to revise the conditions that an entity must meet to elect to use the effective yield method when accounting for qualified affordable housing project investments. Per current accounting guidance, an entity that invests in a qualified affordable housing project may elect to account tor that investment using the effective yield method, current accounting guidance requires that the investments be accounted for under either the equity method or the cost method. Certain existing conditions required to be met to use the effective yield method are restrictive and thus prevent many such investments from qualifying for the use of the effective yield method.
	The ASU replaces the effective yield method with the proportional amortization method and modifies the conditions that an entity must meet to be eligible to use a method other than the equity or cost methods to account for qualified affordable housing project investments. It the modified conditions are met, the ASU permits an entity to use the proportional amortization method to amortize the initial cost of the investment in proportion to the amount of tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. Additionally, the ASU requires new disclosures about all investments in qualified affordable housing projects irrespective of the method used to account for the investments. This guidance is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Under the amended guidance, 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. This guidance is effective for annual and interim periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements, but significant disclosures to the Notes thereto will be required.
	In June 2014, FASB issued ASU No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financing, and Disclosures. The amendments in this guidance require repurchase-to-maturity transactions to be accounted for as secured borrowings. This guidance is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. The adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
