Summary of Significant Accounting Policies (Notes)	12 Months Ended
	Dec. 31, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Summary of Significant Accounting Policies	'
	Basis of Presentation: BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois (the “Company”), is the owner of all of the issued and outstanding capital stock of BankFinancial, F.S.B. (the “Bank”).
	Principles of Consolidation: The consolidated financial statements include the accounts of and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BF Asset Recovery Corporation (collectively, “the Company”). All significant intercompany accounts and transactions have been eliminated.
	Nature of Business: The Company’s revenues, operating income, and assets are primarily from the banking industry. Loan origination customers are mainly located in the greater Chicago metropolitan area. To supplement loan originations, the Company purchases mortgage loans. The loan portfolio is concentrated in loans that are primarily secured by real estate.
	Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, mortgage servicing rights, deferred tax assets, goodwill, other intangible assets, stock-based compensation, impairment of securities and fair value of financial instruments are particularly subject to change and the effect of such change could be material to the financial statements.
	Interest-bearing Deposits in Other Financial Institutions: Interest-bearing deposits in other financial institutions maturing in less than 90 days are carried at cost.
	Cash Flows: Cash and cash equivalents include cash, deposits with other financial institutions maturing in less than 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, borrowings, and advance payments by borrowers for taxes and insurance.
	Securities: Debt securities are classified as available-for-sale when they might be sold before maturity. Equity securities with readily determinable fair values are classified as available-for-sale. Securities available-for-sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income (loss), net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Gains and losses on sales are based on the amortized cost of the security sold. Declines in the fair value of securities below their cost that are other-than-temporary are reflected as realized losses. In determining if losses are other-than-temporary, management considers: (1) the length of time and extent that fair value has been less than cost or adjusted cost, as applicable, (2) the financial condition and near term prospects of the issuer, and (3) whether the Company has the intent to sell the debt security or it is more likely than not that the Company will be required to sell the debt security before the anticipated recovery.
	Securities also include investments in certificates of deposit with maturities of greater than 90 days. These certificates of deposit are placed with insured institutions for varying maturities and amounts that are fully insured by the Federal Deposit Insurance Corporation (“FDIC”).
	Federal Home Loan Bank Stock: The Bank is a member of the Federal Home Loan Bank system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. Federal Home Loan Bank of Chicago (“FHLBC”) stock is carried at cost and classified as a restricted security. Accounting guidance for FHLBC stock provides that, for impairment testing purposes, the value of long term investments such as our FHLBC common stock is based on the “ultimate recoverability” of the par value of the security without regard to temporary declines in value. Both cash and stock dividends are reported as income.
	Loans Held–for–Sale: Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair market value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held–for–sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the fair value of the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
	Held for investment loans that have been transferred to held-for-sale are carried at the lower of cost or fair value. For held-for-sale loans, any decreases in value after transfer below cost are recognized in mortgage banking revenue in the Consolidated Statements of Operations and increases in fair value above cost are not recognized until the loans are sold. The credit component of any write down upon transfer to held-for-sale is reflected in charge-offs to the allowance for loan losses.
	Fair market value is determined based on quoted market rates and our judgment of relevant market conditions. Gains and losses on the disposition of loans held-for-sale are determined on the specific identification method. Transferred mortgage loans sold in the secondary market are sold without retaining servicing rights.
	Loans and Loan Income: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of the allowance for loan losses, premiums and discounts on loans purchased, and net deferred loan costs. Interest income on loans is recognized in income over the term of the loan based on the amount of principal outstanding.
	Premiums and discounts associated with loans purchased are amortized over the contractual term of the loan using the level–yield method.
	Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the contractual loan term, adjusted for prepayments. Interest income is discontinued at the time a loan is 90 days past due or when we do not expect to receive full payment of interest or principal. Past due status is based on the contractual terms of the loan.
	All interest accrued but not received for loans that have been placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash–basis or cost–recovery method until qualifying for return to accrual status. Once a loan is placed on non-accrual status, the borrower must generally demonstrate at least six months of payment performance before the loan is eligible to return to accrual status. Generally, the Company utilizes the “90 days delinquent, still accruing” category of loan classification when: (1) the loan is repaid in full shortly after the period end date; (2) the loan is well secured and there are no asserted or pending legal barriers to its collection; or (3) the borrower has remitted all scheduled payments and is otherwise in substantial compliance with the terms of the loan, but the processing of payments actually received or the renewal of a loan has not occurred for administrative reasons.
	Impaired Loans: Impaired loans consist of nonaccrual loans and troubled debt restructurings (“TDRs”). A loan is considered impaired when, based on current information and events, management believes that it is probable that we will be unable to collect all amounts due (both principal and interest) according to the original contractual terms of the loan agreement. Once a loan is determined to be impaired, the amount of impairment is measured based on the loan's observable fair value, the fair value of the underlying collateral less selling costs if the loan is collateral-dependent, or the present value of expected future cash flows discounted at the loan's effective interest rate. If the measurement of the impaired loan is less than the recorded investment in the loan, the bank's allowance for the impaired collateral dependent loan under ASC 310-10-35 is based on fair value (less costs to sell), but the charge- off (the confirmed “loss”) is based on the higher appraised value. The remaining recorded investment in the loan after the charge-off will have a loan loss allowance for the amount by which the estimated fair value of the collateral (less costs to sell) is less than its appraised value.
	Impaired loans with specific reserves are reviewed quarterly for any changes that would affect the specific reserve. Any impaired loan for which a determination has been made that the economic value is permanently reduced is charged-off against the allowance for loan losses to reflect its current economic value in the period in which the determination has been made.
	At the time a collateral-dependent loan is initially determined to be impaired, we review the existing collateral appraisal. If the most recent appraisal is greater than a year old, a new appraisal is obtained on the underlying collateral. Appraisals are updated with a new independent appraisal at least annually and are formally reviewed by our internal appraisal department upon receipt of a new appraisal. All impaired loans and their related reserves are reviewed and updated each quarter. With an immaterial number of exceptions, all appraisals and internal reviews are current under this methodology at December 31, 2013.
	Purchased Impaired Loans: Purchased impaired loans are recorded at their estimated fair values on the respective purchase dates and are accounted for prospectively based on expected cash flows. No allowance for credit losses is recorded on these loans at the acquisition date. In determining the acquisition date fair value of purchased impaired loans, and in subsequent accounting, the Company reviews these loans on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date (''accretable yield'') are recorded as interest income over the life of the loans if the timing and amount of the future cash flows can be reasonably estimated. The non-accretable yield represents estimated losses in the portfolio and is equal to the difference between contractually required payments and the cash flows expected to be collected at acquisition.
	Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively. The present value of any decreases in expected cash flows after the purchase date is recognized by recording a charge-off through the allowance for loan losses.
	Troubled Debt Restructurings: A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that leads to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses.
	In determining whether a debtor is experiencing financial difficulties, the Company considers if the debtor is in payment default or would be in payment default in the foreseeable future without the modification, the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor has securities that have been or are in the process of being delisted, the debtor's entity-specific projected cash flows will not be sufficient to service any of its debt, or the debtor cannot obtain funds from sources other than the existing creditors at a market rate for debt with similar risk characteristics.
	In determining whether the Company has granted a concession, the Company assesses, if it does not expect to collect all amounts due, whether the current value of the collateral will satisfy the amounts owed, whether additional collateral or guarantees from the debtor will serve as adequate compensation for other terms of the restructuring, and whether the debtor otherwise has access to funds at a market rate for debt with similar risk characteristics.
	A loan that is modified at a market rate of interest will not be classified as troubled debt restructuring in the calendar year subsequent to the restructuring if it is in compliance with the modified terms. Payment performance prior and subsequent to the restructuring is taken into account in assessing whether it is likely that the borrower can meet the new terms. This may result in the loan being returned to accrual at the time of restructuring. A period of sustained repayment for at least six months generally is required for return to accrual status.
	Periodically, the Company will restructure a note into two separate notes (A/B structure), charging off the entire B portion of the note. The A note is structured with appropriate loan-to-value and cash flow coverage ratios that provide for a high likelihood of repayment. The A note is classified as a non-performing note until the borrower has displayed a historical payment performance for a reasonable time prior to and subsequent to the restructuring. A period of sustained repayment for at least six months generally is required to return the note to accrual status provided that management has determined that the performance is reasonably expected to continue. The A note will be classified as a restructured note (either performing or nonperforming) through the calendar year of the restructuring that the historical payment performance has been established.
	Allowance for Loan Losses: The Company establishes provisions for loan losses, which are charged to the Company’s results of operations to maintain the allowance for loan losses to absorb probable incurred credit losses in the loan portfolio. In determining the level of the allowance for loan losses, the Company considers past and current loss experience, trends in classified loans, evaluations of real estate collateral, current economic conditions, volume and type of lending, adverse situations that may affect a borrower’s ability to repay a loan and the levels of nonperforming and other classified loans. The amount of the allowance is based on estimates and the ultimate losses may vary from the estimates as more information becomes available or events change.
	The Company provides for loan losses based on the allowance method. Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to it. Additions to the allowance for loan losses are provided by charges to income based on various factors that, in our judgment, deserve current recognition in estimating probable incurred credit losses. The Company reviews the loan portfolio on an ongoing basis and makes provisions for loan losses on a quarterly basis to maintain the allowance for loan losses in accordance with GAAP. The allowance for loan losses consists of two components:
	•	specific allowances established for any impaired residential non-owner occupied mortgage, multi-family mortgage, nonresidential real estate, construction and land, commercial, and commercial lease loans for which the recorded investment in the loan exceeds the measured value of the loan; and
	•	general allowances for loan losses for each loan class based on historical loan loss experience; and adjustments to historical loss experience (general allowances), maintained to cover uncertainties that affect our estimate of probable incurred credit losses for each loan class. If the remaining unamortized discount related to a specific pool of purchased performing loans exceeds the estimated credit losses associated with these loans, no general valuation allowance is recorded against the loans.
	The adjustments to historical loss experience are based on our evaluation of several factors, including levels of, and trends in, past due and classified loans; levels of, and trends in, charge–offs and recoveries; trends in volume and terms of loans, including any credit concentrations in the loan portfolio; experience and ability of lending management and other relevant staff; and national and local economic trends and conditions.
	The Company evaluates the allowance for loan losses based upon the combined total of the specific and general components. Generally, when the loan portfolio increases, absent other factors, the allowance for loan loss methodology results in a higher dollar amount of estimated probable incurred credit losses than would be the case without the increase. Conversely, when the loan portfolio decreases, absent other factors, the allowance for loan loss methodology generally results in a lower dollar amount of estimated probable losses than would be the case without the decrease.
	The loss ratio used in computing the required general loan loss reserve allowance for a given class of loan consists of (i) the actual loss ratio (measured on a weighted, rolling twelve-quarter basis), (ii) the change in credit quality within the specific loan class during the period, (iii) the actual inherent risk factor assigned to the specific loan class and (iv) the actual concentration of risk factor assigned to the specific loan class (collectively, “the Specific Loan Class Risk Factors”). The Specific Loan Class Risk Factors are weighted equally in the calculation. In addition, two additional quantitative factors, the National Economic risk factor and the Local Economic risk factor, are also components of the computation but are given different weightings in their computation due to their relative applicability to the specific loan class in the context of the effect of national and local economic conditions on their risk profile and performance.
	Mortgage Servicing Rights: Mortgage servicing rights are recognized separately when they are acquired through sales of loans. When mortgage loans are sold, servicing rights are initially recorded at fair value and gains on sales of loans are recorded in the statement of operations. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Company compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans.
	Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with amortization and impairment of servicing assets on the statement of operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
	Servicing fee income that is reported on the statement of operations as loan servicing fees is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material.
	Other Real Estate Owned: Real estate properties acquired in collection of a loan are initially recorded at fair value less cost to sell at acquisition, establishing a new cost basis. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating expenses, gains and losses on disposition, and changes in the valuation allowance are reported in noninterest expense as operations of other real estate owned ("OREO").
	Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is included in noninterest expense and is computed on the straight-line method over the estimated useful lives of the assets. Useful lives are estimated to be 25 to 40 years for buildings and improvements that extend the life of the original building, ten to 20 years for routine building improvements, five to 15 years for furniture and equipment, two to five years for computer hardware and software and no greater than four years on automobiles. The cost of maintenance and repairs is charged to expense as incurred and significant repairs are capitalized.
	Goodwill and Other Intangible Assets: Goodwill represents the excess of cost over the fair value of the net assets of businesses acquired. Goodwill and other intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually. The Company has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. The annual impairment analysis of goodwill includes identification of reporting units, the determination of the carrying value of each reporting unit, including the existing goodwill and intangible assets, and estimating the fair value of each reporting unit. The Company identified one significant reporting unit—banking operations. The Company determined the fair value of our reporting unit and compared it to its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, we are required to perform a second step to the impairment test.
	Our annual impairment analysis as of December 31, 2011, indicated that the step two analysis was necessary. It was determined that the implied value of goodwill was less than the carrying amount, and the Company reduced the full carrying amount of goodwill with a charge to earnings.
	Core deposit intangible assets (“CDI”), are recognized apart from goodwill at the time of acquisition based on valuations prepared by independent third parties or other estimates of fair value. In preparing such valuations, variables such as deposit servicing costs, attrition rates, and market discount rates are considered. CDI assets are amortized to expense over their useful lives.
	Bank Owned Life Insurance: The Company has purchased life insurance policies on certain key executives. The Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
	Long-Term Assets: Premises and equipment, core deposit and other intangible assets, and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
	Loan Commitments and Related Financial Instruments: Financial instruments include off-balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
	Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Under GAAP, a deferred tax asset valuation allowance is required to be recognized if it is “more likely than not” that the deferred tax asset will not be realized. The determination of the realizability of the deferred tax assets is highly subjective and dependent upon judgment concerning management’s evaluation of both positive and negative evidence, the forecasts of future taxable income, applicable tax planning strategies, and assessments of current and future economic and business conditions. The Company considers both positive and negative evidence regarding the ultimate realizability of our deferred tax assets. Examples of positive evidence may include the existence, if any, of taxes paid in available carry-back years and the likelihood that taxable income will be generated in future periods. Examples of negative evidence may include a cumulative loss in the current year and prior two years and negative general business and economic trends. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date.
	Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, the forecasts of future income, taking into account applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. At December 31, 2013 and 2012, after considering both positive and negative evidence, the Company determined that a full valuation allowance for deferred tax assets was required.
	Retirement Plans: Employee 401(k) and profit sharing plan expense is the amount of matching contributions and any annual discretionary contribution made at the discretion of the Company’s Board of Directors. Deferred compensation expense allocates the benefits over years of service.
	Employee Stock Ownership Plan (“ESOP”): The cost of shares issued to the ESOP, but not yet allocated to participants, is shown as a reduction of stockholders’ equity. Compensation expense is based on the market price of shares as they are committed to be released to participant accounts. Dividends on allocated ESOP shares reduce retained earnings; dividends on unearned ESOP shares reduce debt and accrued interest.
	Earnings (Loss) Per Common Share: Basic earnings (loss) per common share is net income (loss) divided by the weighted average number of common shares outstanding during the period. ESOP shares are considered outstanding for this calculation unless unearned. Diluted earnings (loss) per common share is net income (loss) divided by the weighted average number of common shares outstanding during the period plus the dilutive effect of restricted stock shares and the additional potential shares issuable under stock options.
	Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe that there are such matters that will have a material effect on the financial statements as of December 31, 2013.
	Restrictions on Cash: Cash on hand or on deposit with the Federal Reserve Bank which is required to meet regulatory reserve and clearing requirements, based on a percentage of deposits.
	Fair Values of Financial Instruments: Fair values of financial instruments are estimated using relevant market value information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
	Comprehensive Income (Loss): Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities, which are also recognized as separate components of stockholders’ equity.
	Stock-based Compensation: Compensation cost is recognized for stock options and restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. The Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period.
	Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, 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 the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
	Operating Segments: While management monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating results are not reviewed by senior management to make resource allocation or performance decisions. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
	Reclassifications: Certain reclassifications have been made in the prior year’s financial statements to conform to the current year’s presentation.
	Recent Accounting Pronouncements
	In July 2013, the FASB amended existing guidance related to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. These amendments provide that an unrecognized tax benefit, or a portion thereof, be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. Early adoption and retrospective application is permitted. The effect of adopting this standard did not have a material effect on the Company's operating results or financial condition.
	In February 2013, the FASB amended existing guidance related to reporting amounts reclassified out of other comprehensive income out of accumulated other comprehensive income. These amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. These amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional details about those amounts. These amendments are effective prospectively for interim and annual reporting periods beginning after December 31, 2012. The effect of adopting this standard did not have a material effect on the Company's operating results or financial condition.

	An equity mutual fund and certain residential mortgage-backed securities and collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at December 31, 2013, but the unrealized loss was not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is not likely that the Company will be required to sell the securities before their anticipated recovery occurs.

	Loan Origination/Risk Management. The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. The Company reviews and approves these policies and procedures on a periodic basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming and potential problem loans. The Company requires title insurance insuring the priority of our lien, fire and extended coverage casualty insurance, and, if appropriate, flood insurance, in order to protect our security interest in the underlying property.
	The majority of the loans the Company originates are investment and business loans (multi-family, nonresidential real estate, commercial, construction and land loans, and commercial leases). In addition, we originate one-to-four family residential mortgage loans and consumer loans, and purchase and sell loan participations from time-to-time. The following briefly describes our principal loan products.																												Municipal loans	—		—		—		—		2,849		2,849
	The Company originates real estate loans principally secured by first liens on nonresidential real estate. The nonresidential real estate properties are predominantly office buildings, light industrial buildings, shopping centers and mixed-use developments and, to a lesser extent, more specialized properties such as nursing homes and other healthcare facilities. The Company may, from time to time, purchase commercial real estate loan participations.
	Multi-family mortgage loans generally are secured by multi-family rental properties such as apartment buildings, including subsidized apartment units. In general, loan amounts range between $250,000 and $3.0 million. Approximately 22% of the collateral is located outside of our primary market area; however, we do not have a concentration in any single market outside of our primary market territory. In underwriting multi-family mortgage loans, the Company considers a number of factors, which include the projected net cash flow to the loan’s debt service requirement (generally requiring a minimum ratio of 115% for loans below $400,000 and 120% for loans above $400,000), the age and condition of the collateral, the financial resources and income level of the borrower and the borrower’s experience in owning or managing similar properties. Multi-family mortgage loans are generally originated in amounts up to 80% of the appraised value of the property securing the loan. Personal guarantees are usually obtained from multi-family mortgage borrowers.																												Warehouse lines	—		—		—		—		1,927		1,927
	Loans secured by multi-family mortgages generally involve a greater degree of credit risk than one- to four-family residential mortgage loans and carry larger loan balances. This increased credit risk is a result of several factors, including the concentration of principal in a limited number of loans and borrowers, the effects of general economic conditions on income producing properties, and the increased difficulty of evaluating and monitoring these types of loans. Furthermore, the repayment of loans secured by multi-family mortgages typically depends upon the successful operation of the related real estate property. If the cash flow from the project is reduced below acceptable thresholds, the borrower’s ability to repay the loan may be impaired.
	The Company emphasizes nonresidential real estate loans with initial principal balances between $250,000 and $3.0 million. Substantially all of our nonresidential real estate loans are secured by properties located in our primary market area. The Company’s nonresidential real estate loans are generally written as three- or five-year adjustable-rate mortgages or mortgages with balloon maturities of three or five years. Amortization on these loans is typically based on 20- to 25-year schedules. The Company also originates some 15-year fixed-rate, fully amortizing loans.																												Health care	—		—		—		—		19,381		19,381
	In the underwriting of nonresidential real estate loans, the Company generally lends up to 80% of the property’s appraised value. Decisions to lend are based on the economic viability of the property as the primary source of repayment and the creditworthiness of the borrower. In evaluating a proposed commercial real estate loan, we emphasize the ratio of the property’s projected net cash flow to the loan’s debt service requirement (generally requiring a minimum ratio of 120%), computed after deduction for a vacancy factor and property expenses we deem appropriate. Personal guarantees are usually obtained from nonresidential real estate borrowers.
	Nonresidential real estate loans generally carry higher interest rates and have shorter terms than those on one- to four-family residential mortgage loans. Nonresidential real estate loans, however, entail significant additional credit risks compared to one- to four-family residential mortgage loans, as they typically involve larger loan balances concentrated with single borrowers or groups of related borrowers. In addition, the payment of loans secured by income-producing properties typically depends on the successful operation of the related real estate project and thus may be subject to a greater extent to adverse conditions in the real estate market and in the general economy.																												Aviation	—		—		—		—		1,102		1,102
	The Company makes various types of secured and unsecured commercial loans to customers in our market area for the purpose of financing equipment acquisition, expansion, working capital and other general business purposes. The terms of these loans generally range from less than one year to five years. The loans are either negotiated on a fixed-rate basis or carry adjustable interest rates indexed to (i) a lending rate that is determined internally, or (ii) a short-term market rate index.
	Commercial credit decisions are based upon our credit assessment of the loan applicant. The Company determines the applicant’s ability to repay in accordance with the proposed terms of the loans and we assess the risks involved. An evaluation is made of the applicant to determine character and capacity to manage. Personal guarantees of the principals are usually obtained. In addition to evaluating the loan applicant’s financial statements, we consider the adequacy of the primary and secondary sources of repayment for the loan. Credit agency reports of the applicant’s credit history supplement our analysis of the applicant’s creditworthiness and at times are supplemented with inquiries to other banks and trade investigations. Collateral supporting a secured transaction also is analyzed to determine its marketability. Commercial business loans generally have higher interest rates than residential loans of like duration because they have a higher risk of default since their repayment generally depends on the successful operation of the borrower’s business and the sufficiency of any collateral. Pricing of commercial loans is based primarily on the credit risk of the borrower, with due consideration given to borrowers with appropriate deposit relationships.

	The Company also lends money to small and mid-size leasing companies for equipment financing leases. Generally, commercial leases are secured by an assignment by the leasing company of the lease payments and by a secured interest in the equipment being leased. The lessee acknowledges our security interest in the leased equipment and agrees to send lease payments directly to us. Consequently, the Company underwrites lease loans by examining the creditworthiness of the lessee rather than the lessor. Lease loans generally are non-recourse to the leasing company.
	The Company’s commercial leases are secured primarily by technology equipment, medical equipment, material handling equipment and other capital equipment. Lessees tend to be publicly-traded companies with investment-grade rated debt or companies that have not issued public debt and therefore do not have a public debt rating. The Company requires that a minimum of 50% of our commercial lessees have an investment grade public debt rating by Moody’s or Standard & Poors, or the equivalent. Commercial leases to these entities have a maximum maturity of seven years and a maximum outstanding credit exposure of $15.0 million to any single entity. Lessees without public debt ratings generally have net worth in excess of $25.0 million. If the lessee does not have a public debt rating, they are subject to the same internal credit analysis as any other customer. Commercial leases to these lessees have a maximum maturity of five years and a maximum outstanding credit exposure of $5.0 million to any single entity. In addition, the Company will originate commercial leases to lessees with below-investment grade public debt ratings, but these leases are limited to 10% of our commercial lease portfolio and have a maximum outstanding credit exposure of $3.0 million to any single entity. Lease loans are almost always fully amortizing, with fixed interest rates.																												Commercial leases:
	Although the Company does not actively originate construction and land loans presently, construction and land loans generally consist of land acquisition loans to help finance the purchase of land intended for further development, including single-family homes, multi-family housing and commercial income property, development loans to builders in our market area to finance improvements to real estate, consisting mostly of single-family subdivisions, typically to finance the cost of utilities, roads, sewers and other development costs. These builders generally rely on the sale of single-family homes to repay development loans, although in some cases the improved building lots may be sold to another builder, often in conjunction with development loans. Construction and land loans typically involve a higher degree of credit risk than financing on improved, owner-occupied real estate. The risk of loss on construction and land loans is largely dependent upon the accuracy of the initial appraisal of the property’s value upon completion of construction or development; the estimated cost of construction, including interest; and the estimated time to complete and/or sell or lease such property. The Company seeks to minimize these risks by maintaining consistent lending policies and underwriting standards. However, if the estimate of value proves to be inaccurate, the cost of completion is greater than expected, the length of time to complete and/or sell or lease the collateral property is greater than anticipated, or if there is a downturn in the local economy or real estate market, the property could have a value upon completion that is insufficient to assure full repayment of the loan. This could have a material adverse effect on the quality of the construction and land loan portfolio, and could result in significant losses or delinquencies.
	The Company offers conforming and non-conforming, fixed-rate and adjustable-rate residential mortgage loans with maturities of up to 30 years and maximum loan amounts generally of up to $2.5 million. The Company currently offers fixed-rate conventional mortgage loans with terms of 10 to 30 years that are fully amortizing with monthly payments, and adjustable-rate conventional mortgage loans with initial terms of between one and five years that amortize up to 30 years. One- to four-family residential mortgage loans are generally underwritten according to Fannie Mae guidelines, and loans that conform to such guidelines are referred to as “conforming loans.” The Company generally originates both fixed- and adjustable-rate loans in amounts up to the maximum conforming loan limits as established by Fannie Mae, which is currently $417,000 for single-family homes. Private mortgage insurance is required for first mortgage loans with loan-to-value ratios in excess of 80%.																												Investment rated commercial leases	—		—		—		—		147,374		147,374
	The Company also originates loans above conforming limits, sometimes referred to as “jumbo loans,” that have been underwritten to the credit standards of Fannie Mae. These loans are generally eligible for sale to various firms that specialize in the purchase of such non-conforming loans. In the Chicago metropolitan area, larger residential loans are not uncommon. The Company also originates loans at higher rates that do not fully meet the credit standards of Fannie Mae but are deemed to be acceptable risks.
	The primary markets served by the Company have seen gradually broadening signs of stability amid widespread economic weakness and high unemployment. The ability of the Company’s borrowers to repay their loans, and the value of the collateral securing such loans, could be adversely impacted by a return to economic weakness in its local markets as a result of unemployment, declining real estate values, or increased residential and office vacancies. This not only could result in the Company experiencing charge-offs and/or nonperforming assets, but also could necessitate an increase in the provision for loan losses. These events, if they were to recur, would have an adverse impact on the Company’s results of operations and its capital.																												Below investment grade	8		—		—		8		14,739		14,747

Purchased Impaired Loans
As a result of its acquisition of Downers Grove National Bank, the Company holds purchased loans for which there was evidence of deterioration of credit quality since origination and for which it was probable that all contractually required payments would not be collected as of the date of the acquisition. The carrying amount of these purchased impaired loans is as follows:

For the above purchased impaired loans, the Company decreased the allowance for loan losses by $105,000 for the year ended December 31, 2013 and increased the allowance for loan losses by $110,000 for the year ended December 31, 2012.
Purchased impaired loans for which it was probable at the date of acquisition that all contractually required payments would not be collected are as follows:

Nonresidential real estate	1,999				3,884
Land	—				1,600
Commercial loans	222				597
	$	3,053			$	7,224
At acquisition, cash flows expected to be collected were $18.8 million, compared to the fair value of purchased impaired loans of $15.4 million.
The Company’s reserve for uncollected loan interest was $1.3 million and $942,000 at December 31, 2013 and 2012, respectively. Except for purchased impaired loans, when a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.
Troubled Debt Restructurings
The Company evaluates loan extensions or modifications in accordance with FASB ASC 310–40 with respect to the classification of the loan as a TDR. In general, if the Company grants a loan extension or modification to a borrower for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above.
The Company had $3.3 million of TDRs at December 31, 2013, compared to $11.2 million at December 31, 2012, with $53,000 and $318,000 in specific valuation reserves allocated at December 31, 2013 and 2012, respectively. The Company had no outstanding commitments to borrowers whose loans are classified as TDRs.
The following table presents loans classified as TDRs:

	$	3,337			$	11,167
During the years ending December 31, 2013 and 2012, the terms of certain loans were modified and classified as TDRs. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan.
The following tables present TDRs that occurred during the year:

The TDRs described above had no impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in charge offs of $25,000 for the year ended December 31, 2013. The TDRs decreased interest income by $9,000, increased the allowance for loan losses allocated by $62,000 and resulted in charge offs of $2.0 million during the year ended December 31, 2012.
The following table presents TDRs for which there was a payment default within twelve months following the modification:

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.
The TDRs that subsequently defaulted described above had no material impact on the allowance for loans losses during the year ending December 31, 2012.
The terms of certain other loans were modified during the year ending December 31, 2013 that did not meet the definition of a TDR. These loans have a total recorded investment of $1.7 million and $1.2 million at December 31, 2013 and 2012. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant.
In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy.
Credit Quality Indicators:
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings:
Special Mention. A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.
Substandard. Loans categorized as substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard.
Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The loans were placed on nonaccrual status.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans.
As of December 31, 2013, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows:

	First mortgage loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balances of these loans were $164.6 million, $186.8 million, and $206.1 million at December 31, 2013, 2012, and 2011, respectively. Custodial escrow balances maintained in connection with the foregoing loan servicing activities were $3.5 million, $4.9 million, and $5.8 million at December 31, 2013, 2012, and 2011, respectively.
	Capitalized mortgage servicing rights are included in other assets in the accompanying consolidated statements of financial condition. Activity for capitalized mortgage servicing rights and the related valuation allowance was as follows.

	Beginning of year	$	1,090			$	1,219

	Carrying value of mortgage servicing rights	$	926			$	1,020
	Fair value of mortgage servicing rights	$	1,279			$	1,340
	The estimated fair value of mortgage servicing rights is the present value of the expected future cash flows over the projected life of the loan. Assumptions used in the present value calculation are based on actual performance of the underlying servicing along with general market consensus. The expected cash flow is the net amount of all mortgage servicing income and expense items. The expected cash flows are discounted at an interest rate appropriate for the associated risk given the current market conditions. Significant assumptions are as follows:
		December 31,
		2013			2012
	Prepayment speed	14.22	%		15.86	%
	Discount rate	12	%		12	%
	Average servicing cost per loan	$65.00			$72.00
	Escrow float rate	1.67	%		0.86	%
	Key economic assumptions used in measuring the fair value of the Company’s mortgage servicing rights as of December 31, 2013 and the effect on the fair value of our mortgage servicing rights from adverse changes in those assumptions, are as follows:
	Fair value of mortgage servicing rights	$	1,279
	Weighted average annual prepayment speed	14.22		%
	Decrease in fair value from 10% adverse change	(27		)
	Decrease in fair value from 20% adverse change	(53		)
	Weighted-average annual discount rate	12		%
	Decrease in fair value from 10% adverse change	(47		)
	Decrease in fair value from 20% adverse change	(92		)
	These sensitivities are hypothetical and should be used with caution. As the above table indicates, changes in fair value based on variations in individual assumptions generally cannot be used to predict changes in fair value based upon further variations of the same assumptions. Also, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated in the above table independently, without changing any other assumption. In reality, changes in one factor may result in changes in another factor, which might magnify or counteract the sensitivities.
	The weighted average amortization period is 51 months. The estimated amortization expense for each of the next five years is as follows:
	2014	$	206
	2015	139
	2016	111
	2017	89

		$	—		$	—
	A deferred tax asset valuation allowance is required to be recognized if it is “more likely than not” that the deferred tax asset will not be realized. The determination of the realizability of the deferred tax assets is highly subjective and dependent upon judgment concerning management’s evaluation of both positive and negative evidence, the forecasts of future taxable income, applicable tax planning strategies, and assessments of current and future economic and business conditions. The Company considered both positive and negative evidence regarding the ultimate realizability of its deferred tax assets. Examples of positive evidence may include the existence, if any, of taxes paid in available carry-back years and the likelihood that taxable income will be generated in future periods. Examples of negative evidence may include a cumulative loss in the current year and prior two years and negative general business and economic trends. In assessing the realization of deferred tax assets at December 31, 2013 and 2012, the Company concluded that it was more likely than not that the Company will not realize the benefits of these deductible differences at December 31, 2013 and 2012, and therefore, a full valuation allowance for deferred tax assets was recorded in the amount of $35.1 million and $33.8 million at December 31, 2013 and 2012, respectively.
	At December 31, 2013, the Company had a federal net operating loss carryforward of $60.4 million, which will begin to expire in 2029, a federal tax credit carryforward of $1.3 million which will begin to expire in 2022, a $2.5 million alternative minimum tax credit carryforward that can be carried forward indefinitely, and a $53.6 million federal alternative minimum tax net operating loss carryforward which will begin to expire in 2031. In addition, at December 31, 2013 the Company had a federal net operating loss carryforward relating to its acquisition of Downers Grove National Bank, which is subject to utilization limitations under Section 382 of the Internal Revenue Code, of $8.6 million which will begin to expire in 2030. At December 31, 2013, the Company had a state net operating loss carryforward for the State of Illinois of $96.9 million, which will begin to expire in 2025.
	Unrecognized Tax Benefits
	A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	Reductions due to the statute of limitations and reductions for tax positions of prior years	(62		)	(116		)
	End of year	$	65		$	125
	The Company does not expect the total amount of unrecognized tax benefits to significantly increase or decrease in the next twelve months. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. At December 31, 2013 and 2012, the Company has immaterial amounts accrued for potential interest and penalties.
	The Company and its subsidiary are subject to U.S. federal income tax as well as income tax of the States of Illinois, New Jersey, Colorado, Minnesota and Texas. Beginning in 2013, the Bank became subject to income taxes in the States of Minnesota and Texas due to the physical presence of Wholesale Commercial bankers in these jurisdictions. The Company is no longer subject to examination by the federal taxing authorities for years before 2010 and the Illinois taxing authorities for years before 2010.

The minimum capital ratios set forth in the Capital Plans will be increased and other minimum capital requirements will be established if and as necessary to comply with the Basel III requirements as such requirements become applicable to the Company and the Bank. In accordance with the Capital Plans, neither the Company nor the Bank will pursue any acquisition or growth opportunity, declare any dividend or conduct any stock repurchase that would cause the Bank’s total risk-based capital ratio and/or its Tier 1 leverage ratio to fall below the established minimum capital levels. In addition, the Company will continue to maintain its ability to serve as a source of financial strength to the Bank by holding at least $5.0 million of cash or liquid assets for that purpose.
	Federal regulations require the Bank to comply with a Qualified Thrift Lender (“QTL”) test, which generally requires that 65% of assets be maintained in housing-related finance and other specified assets. If the QTL test is not met, limits are placed on growth, branching, new investment, FHLBC advances, and dividends or the institution must convert to a commercial bank charter. Management considers the QTL test to have been met as of December 31, 2013.
	The Bank is subject to restrictions on the amount of dividends it may declare and pay to the Company without prior regulatory approval. At December 31, 2013, the Bank does not have pre-approved approval for future dividends.

	Employee Stock Ownership Plan. Employees are eligible to participate in the ESOP after attainment of age 21 and completion of one year of service. In connection with the conversion and reorganization, the ESOP borrowed $19.6 million from the Company, and used the proceeds of the loan to purchase 1,957,300 shares of common stock issued in the subscription offering at $10.00 per share. The loan is secured by the shares and will be repaid by the ESOP with funds from the Bank’s discretionary contributions to the ESOP and earnings on ESOP assets. The Bank has committed to make discretionary contributions to the ESOP sufficient to service the loan over a period not to exceed 20 years. When loan payments are made, ESOP shares are allocated to participants based on relative compensation and expense is recorded. Participants receive their earned shares at the end of employment.
	Contributions to the ESOP were $1.5 million for the years ended December 31, 2013 and 2012, including dividends and interest received on unallocated shares of $49,000 and $40,000 in 2013 and 2012, respectively.
	Expense related to the ESOP, net of dividends and interest received on unallocated ESOP shares, was $847,000, $686,000 and $228,000 for the years ended December 31, 2013, 2012 and 2011, respectively.
	Shares held by the ESOP were as follows:

Equity Incentive Plans	'
	On June 27, 2006, the Company’s stockholders approved the BankFinancial Corporation 2006 Equity Incentive Plan, which authorized the Human Resources Committee of the Board of Directors of the Company to grant a variety of cash- and equity-based incentive awards, including stock options, stock appreciation rights, restricted stock, performance shares and other incentive awards, to employees and directors aggregating up to 3,425,275 shares of the Company’s common stock.
	The Human Resources Committee may grant stock options to purchase shares of the Company’s common stock to certain employees and directors of the Company. The exercise price for the stock options is the fair market value of the common stock on the dates of the grants. The stock options generally vest annually over 3 to 5 year periods; vesting is subject to acceleration in certain circumstances. The stock options will expire if not exercised within 5 years from the date of grant.
	The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. The risk-free interest rate was determined using the yield available on the option grant date for a zero-coupon U.S. Treasury security with a term equivalent to the expected life of the option. The expected life for options granted represents the period the option is expected to be outstanding and was determined by applying the simplified method as allowed by SAB 107. The expected volatility for options issued in 2009 was determined using the Company’s historical data. Estimated forfeitures were assumed to be zero due to the lack of historical experience for the Company. There were no options granted in 2013 or 2012.
	The Company recognized $12,000 of stock-based compensation expenses relating to the granting of stock options for the year ended December 31, 2011. There was no expense recorded for the years ended December 31, 2013, and 2012.
	On September 2, 2011, the Human Resources Committee and the Board of Directors of the Company approved a one year extension of stock options granted in prior years that were scheduled to expire in September and December of 2011. After the extensions, the stock options expired in September and December of 2012. The extensions only involved the expiration date of the stock options and do not affect their other terms. There was no expense recorded with the extension of the options. The extended stock options provided the holders with an option to purchase 1,858,403 shares of the Company’s common stock at a weighted average exercise price of $16.62.  As of December 31, 2013 and 2012, there were no stock options outstanding.

Loan Commitments and Other Off-Balance Sheet Activities [Abstract]	'
Loan Commitments and Other Off-Balance Sheet Activities	'
	The Company is party to various financial instruments with off-balance-sheet risk. The Company uses these financial instruments in the normal course of business to meet the financing needs of customers and to effectively manage exposure to interest rate risk. These financial instruments include commitments to extend credit, standby letters of credit, unused lines of credit, and commitments to sell loans. When viewed in terms of the maximum exposure, those instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. Credit risk is the possibility that a counterparty to a financial instrument will be unable to perform its contractual obligations. Interest rate risk is the possibility that, due to changes in economic conditions, the Company’s net interest income will be adversely affected.
	The following is a summary of the contractual or notional amount of each significant class of off-balance-sheet financial instruments outstanding. The Company’s exposure to credit loss in the event of nonperformance by the counterparty for commitments to extend credit, standby letters of credit, and unused lines of credit is represented by the contractual notional amount of these instruments.
	The contractual or notional amounts are as follows:
		December 31,
		2013		2012
	Financial instruments wherein contractual amounts represent credit risk
	Commitments to extend credit	$	29,253	$	15,971
	Standby letters of credit	922		1,237
	Unused lines of credit	118,167		120,733
	Commitments to sell mortgages	222		1,268
	Commitments to extend credit are generally made for periods of 60 days or less. The fixed-rate loans commitment totaled $17.3 million with interest rates ranging from 2.25% to 5.04% and maturities ranging from 1 to 30 years.
	Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customers. The collateral held varies, but primarily consists of single-family residential real estate.
	The Bank, as a member of Visa USA, received 51,404 unrestricted shares of Visa, Inc. Class B common stock in connection with Visa, Inc.’s initial public offering in 2007, and 32,398 additional shares of Class B common stock that were deposited into a litigation escrow that Visa, Inc. established under its retrospective responsibility plan. The retroactive responsibility plan obligates all former Visa USA members to indemnify Visa USA, in proportion to their equity interests in Visa USA, for certain litigation losses and expenses, including settlement expenses, for the lawsuits covered by the retrospective responsibility plan. The primary method for discharging the indemnification obligations under the retrospective responsibility plan is a reduction of the ratio at which the Visa, Inc. Class B shares held in the litigation escrow can be converted into publicly traded Class A common shares of Visa, Inc. Due to the restrictions that the retrospective responsibility plan imposes on the Company’s Visa, Inc. Class B shares, the Company has not recorded the Class B shares as an asset.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:
	•	Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.
	•	Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs 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 that market participants would use in pricing an asset or liability.
	The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:
	Securities: The fair values of marketable equity securities are generally determined by quoted prices, in active markets, for each specific security (Level 1). If Level 1 measurement inputs are not available for a marketable equity security, we determine its fair value based on the quoted price of a similar security traded in an active market (Level 2). The fair values of debt securities are generally determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2).
	Loans Held for Sale: Loans held for sale are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2).
	Impaired Loans: At the time a loan is considered impaired, management measures impairment in accordance with ASC Topic 310. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Impaired loans carried at fair value generally require a partial charge off and a specific valuation allowance for loan losses. For collateral dependent loans, fair value is commonly based on recent real estate appraisals. These real estate appraisals may include up to three approaches to value: the sales comparison approach, the income approach (for income-producing property) and the cost approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available, if applicable. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. In addition, a discount is typically applied to account for sales and holding expenses. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. The method utilized to estimate the fair value of loans does not necessarily represent an exit price.
	Other Real Estate Owned: Assets acquired through foreclosure or transfers in lieu of foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. Although the fair value of the property normally will be based on an appraisal (or other evaluation), the valuation should be consistent with the price that a market participant will pay to purchase the property at the measurement date. Circumstances may exist that indicate that the appraised value is not an accurate measurement of the property's current fair value. Examples of such circumstances include changed economic conditions since the last appraisal, stale appraisals, or imprecision and subjectivity in the appraisal process (i.e., actual sales for less than the appraised amount). Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value.
	Mortgage Servicing Rights: On a quarterly basis, loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. The fair values of mortgage servicing rights are based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income. The Company is able to compare the valuation model inputs and results to widely available published industry data for reasonableness (Level 2).
	The following table sets forth the Company’s financial assets that were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Impaired loans, which are measured for impairment using the fair value of the collateral for collateral–dependent loans, had a carrying amount of $4.2 million, with a valuation allowance of $375,000 at December 31, 2013, compared to a carrying amount of $10.1 million and a valuation allowance of $1.7 million at December 31, 2012, resulting in a decrease in the provision for loan losses of $1.3 million for the year ended December 31, 2013.
OREO is carried at the lower of cost or fair value less costs to sell, had a carrying value of $2.7 million less a valuation allowance of $902,000, or $1.8 million at December 31, 2013, compared to $10.5 million less a valuation allowance of $1.2 million, or $9.4 million at December 31, 2012. There were $550,000 of valuation adjustments of other real estate owned recorded for the year ended December 31, 2013.
Mortgage servicing rights, which are carried at lower of cost or fair value, had a carrying amount of $198,000 at December 31, 2013, and $208,000 at December 31, 2012. A pre–tax recovery of $65,000 on our mortgage servicing rights portfolio was included in noninterest income for the year ended December 31, 2013, compared to a $55,000 provision for the same period in 2012.

For purposes of the above, the following assumptions were used:
Cash and Cash Equivalents: The estimated fair values for cash and cash equivalents are based on their carrying value due to the short-term nature of these assets.
Loans: The estimated fair value for loans has been determined by calculating the present value of future cash flows based on the current rate the Company would charge for similar loans with similar maturities, applied for an estimated time period until the loan is assumed to be repriced or repaid. The estimated fair values of loans held-for-sale are based on outstanding commitments from third party investors.
FHLBC Stock: It is not practicable to determine the fair value of FHLBC stock due to the restrictions placed on its transferability.
Deposit Liabilities: The estimated fair value for certificates of deposit has been determined by calculating the present value of future cash flows based on estimates of rates the Company would pay on such deposits, applied for the time period until maturity. The estimated fair values of noninterest-bearing demand, NOW, money market, and savings deposits are assumed to approximate their carrying values as management establishes rates on these deposits at a level that approximates the local market area. Additionally, these deposits can be withdrawn on demand.
Borrowings: The estimated fair values of advances from the FHLBC and notes payable are based on current market rates for similar financing. The estimated fair value of securities sold under agreements to repurchase is assumed to equal its carrying value due to the short-term nature of the liability.
Accrued Interest: The estimated fair values of accrued interest receivable and payable are assumed to equal their carrying value.
Off-Balance-Sheet Instruments: Off-balance-sheet items consist principally of unfunded loan commitments, standby letters of credit, and unused lines of credit. The estimated fair values of unfunded loan commitments, standby letters of credit, and unused lines of credit are not material.
While the above estimates are based on management’s judgment of the most appropriate factors, as of the balance sheet date, there is no assurance that the estimated fair values would have been realized if the assets were disposed of or the liabilities settled at that date, since market values may differ depending on the various circumstances. The estimated fair values would also not apply to subsequent dates.
In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the above disclosures.

	The Company recorded net income of $1.5 million for the fourth quarter of 2013. The Company’s net interest income before provision for loan losses increased to $11.5 million due to stronger loan originations and improved asset quality. The Company’s fourth quarter 2013 operating results included a $1.2 million recovery of loan losses. The recovery is primarily due to the growth in our loan portfolio was focused on loan types with lower loss ratios based on our historical loss experience and the historical loan loss factors improved as the losses incurred in earlier periods aged, therefore are weighted less in the calculation. Noninterest expense included $811,000 of nonperforming asset management and OREO expense.

	The Company recorded a net loss of $25.0 million for the fourth quarter of 2012. The Company’s fourth quarter 2012 operating results included a $24.3 million provision for loan losses. In late 2012, the Company completed several actions to materially reduce future nonperforming asset expenses. The Company completed two bulk sales of certain nonperforming assets with a carrying value of $22.7 million, reclassified $7.5 million of loans as held-for-sale in preparation for a third bulk sale, and restructured $7.1 million of performing classified loans to enable the basis for their classification to be resolved in 2013. These actions resulted in pre-tax charges of $19.4 million. Noninterest expense included $3.6 million of nonperforming asset management and OREO expense.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Basis of Presentation	'
	Basis of Presentation: BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois (the “Company”), is the owner of all of the issued and outstanding capital stock of BankFinancial, F.S.B. (the “Bank”).
Principles of Consolidation	'
	Principles of Consolidation: The consolidated financial statements include the accounts of and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BF Asset Recovery Corporation (collectively, “the Company”). All significant intercompany accounts and transactions have been eliminated.
Use of Estimates	'
	Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”), management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, mortgage servicing rights, deferred tax assets, goodwill, other intangible assets, stock-based compensation, impairment of securities and fair value of financial instruments are particularly subject to change and the effect of such change could be material to the financial statements.
Cash Flows	'
	Interest-bearing Deposits in Other Financial Institutions: Interest-bearing deposits in other financial institutions maturing in less than 90 days are carried at cost.
	Cash Flows: Cash and cash equivalents include cash, deposits with other financial institutions maturing in less than 90 days, and daily federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, borrowings, and advance payments by borrowers for taxes and insurance.
Securities	'
	Securities: Debt securities are classified as available-for-sale when they might be sold before maturity. Equity securities with readily determinable fair values are classified as available-for-sale. Securities available-for-sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income (loss), net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Gains and losses on sales are based on the amortized cost of the security sold. Declines in the fair value of securities below their cost that are other-than-temporary are reflected as realized losses. In determining if losses are other-than-temporary, management considers: (1) the length of time and extent that fair value has been less than cost or adjusted cost, as applicable, (2) the financial condition and near term prospects of the issuer, and (3) whether the Company has the intent to sell the debt security or it is more likely than not that the Company will be required to sell the debt security before the anticipated recovery.
Federal Home Loan Bank Stock	'
	Federal Home Loan Bank Stock: The Bank is a member of the Federal Home Loan Bank system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. Federal Home Loan Bank of Chicago (“FHLBC”) stock is carried at cost and classified as a restricted security. Accounting guidance for FHLBC stock provides that, for impairment testing purposes, the value of long term investments such as our FHLBC common stock is based on the “ultimate recoverability” of the par value of the security without regard to temporary declines in value. Both cash and stock dividends are reported as income.
Loans Held-for-Sale	'
	Loans Held–for–Sale: Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair market value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held–for–sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the fair value of the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
	Held for investment loans that have been transferred to held-for-sale are carried at the lower of cost or fair value. For held-for-sale loans, any decreases in value after transfer below cost are recognized in mortgage banking revenue in the Consolidated Statements of Operations and increases in fair value above cost are not recognized until the loans are sold. The credit component of any write down upon transfer to held-for-sale is reflected in charge-offs to the allowance for loan losses.
	Fair market value is determined based on quoted market rates and our judgment of relevant market conditions. Gains and losses on the disposition of loans held-for-sale are determined on the specific identification method. Transferred mortgage loans sold in the secondary market are sold without retaining servicing rights.
Loans And Loan Income	'
	Loans and Loan Income: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of the allowance for loan losses, premiums and discounts on loans purchased, and net deferred loan costs. Interest income on loans is recognized in income over the term of the loan based on the amount of principal outstanding.
	Premiums and discounts associated with loans purchased are amortized over the contractual term of the loan using the level–yield method.
	Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the contractual loan term, adjusted for prepayments. Interest income is discontinued at the time a loan is 90 days past due or when we do not expect to receive full payment of interest or principal. Past due status is based on the contractual terms of the loan.
	All interest accrued but not received for loans that have been placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash–basis or cost–recovery method until qualifying for return to accrual status. Once a loan is placed on non-accrual status, the borrower must generally demonstrate at least six months of payment performance before the loan is eligible to return to accrual status. Generally, the Company utilizes the “90 days delinquent, still accruing” category of loan classification when: (1) the loan is repaid in full shortly after the period end date; (2) the loan is well secured and there are no asserted or pending legal barriers to its collection; or (3) the borrower has remitted all scheduled payments and is otherwise in substantial compliance with the terms of the loan, but the processing of payments actually received or the renewal of a loan has not occurred for administrative reasons.
Impaired Loans	'
	Impaired Loans: Impaired loans consist of nonaccrual loans and troubled debt restructurings (“TDRs”). A loan is considered impaired when, based on current information and events, management believes that it is probable that we will be unable to collect all amounts due (both principal and interest) according to the original contractual terms of the loan agreement. Once a loan is determined to be impaired, the amount of impairment is measured based on the loan's observable fair value, the fair value of the underlying collateral less selling costs if the loan is collateral-dependent, or the present value of expected future cash flows discounted at the loan's effective interest rate. If the measurement of the impaired loan is less than the recorded investment in the loan, the bank's allowance for the impaired collateral dependent loan under ASC 310-10-35 is based on fair value (less costs to sell), but the charge- off (the confirmed “loss”) is based on the higher appraised value. The remaining recorded investment in the loan after the charge-off will have a loan loss allowance for the amount by which the estimated fair value of the collateral (less costs to sell) is less than its appraised value.
	Impaired loans with specific reserves are reviewed quarterly for any changes that would affect the specific reserve. Any impaired loan for which a determination has been made that the economic value is permanently reduced is charged-off against the allowance for loan losses to reflect its current economic value in the period in which the determination has been made.
	At the time a collateral-dependent loan is initially determined to be impaired, we review the existing collateral appraisal. If the most recent appraisal is greater than a year old, a new appraisal is obtained on the underlying collateral. Appraisals are updated with a new independent appraisal at least annually and are formally reviewed by our internal appraisal department upon receipt of a new appraisal. All impaired loans and their related reserves are reviewed and updated each quarter. With an immaterial number of exceptions, all appraisals and internal reviews are current under this methodology at December 31, 2013.
Purchased Impaired Loans	'
	Purchased Impaired Loans: Purchased impaired loans are recorded at their estimated fair values on the respective purchase dates and are accounted for prospectively based on expected cash flows. No allowance for credit losses is recorded on these loans at the acquisition date. In determining the acquisition date fair value of purchased impaired loans, and in subsequent accounting, the Company reviews these loans on an individual basis. Expected future cash flows in excess of the fair value of loans at the purchase date (''accretable yield'') are recorded as interest income over the life of the loans if the timing and amount of the future cash flows can be reasonably estimated. The non-accretable yield represents estimated losses in the portfolio and is equal to the difference between contractually required payments and the cash flows expected to be collected at acquisition.
	Subsequent to the purchase date, increases in cash flows over those expected at the purchase date are recognized as interest income prospectively. The present value of any decreases in expected cash flows after the purchase date is recognized by recording a charge-off through the allowance for loan losses.
Troubled Debt Restructurings	'
	Troubled Debt Restructurings: A loan is classified as a troubled debt restructuring when a borrower is experiencing financial difficulties that leads to a restructuring of the loan, and the Company grants concessions to the borrower in the restructuring that it would not otherwise consider. These concessions may include rate reductions, principal forgiveness, extension of maturity date and other actions intended to minimize potential losses.
	In determining whether a debtor is experiencing financial difficulties, the Company considers if the debtor is in payment default or would be in payment default in the foreseeable future without the modification, the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor has securities that have been or are in the process of being delisted, the debtor's entity-specific projected cash flows will not be sufficient to service any of its debt, or the debtor cannot obtain funds from sources other than the existing creditors at a market rate for debt with similar risk characteristics.
	In determining whether the Company has granted a concession, the Company assesses, if it does not expect to collect all amounts due, whether the current value of the collateral will satisfy the amounts owed, whether additional collateral or guarantees from the debtor will serve as adequate compensation for other terms of the restructuring, and whether the debtor otherwise has access to funds at a market rate for debt with similar risk characteristics.
	A loan that is modified at a market rate of interest will not be classified as troubled debt restructuring in the calendar year subsequent to the restructuring if it is in compliance with the modified terms. Payment performance prior and subsequent to the restructuring is taken into account in assessing whether it is likely that the borrower can meet the new terms. This may result in the loan being returned to accrual at the time of restructuring. A period of sustained repayment for at least six months generally is required for return to accrual status.
	Periodically, the Company will restructure a note into two separate notes (A/B structure), charging off the entire B portion of the note. The A note is structured with appropriate loan-to-value and cash flow coverage ratios that provide for a high likelihood of repayment. The A note is classified as a non-performing note until the borrower has displayed a historical payment performance for a reasonable time prior to and subsequent to the restructuring. A period of sustained repayment for at least six months generally is required to return the note to accrual status provided that management has determined that the performance is reasonably expected to continue. The A note will be classified as a restructured note (either performing or nonperforming) through the calendar year of the restructuring that the historical payment performance has been established.
Allowance for Loan Losses	'
	Allowance for Loan Losses: The Company establishes provisions for loan losses, which are charged to the Company’s results of operations to maintain the allowance for loan losses to absorb probable incurred credit losses in the loan portfolio. In determining the level of the allowance for loan losses, the Company considers past and current loss experience, trends in classified loans, evaluations of real estate collateral, current economic conditions, volume and type of lending, adverse situations that may affect a borrower’s ability to repay a loan and the levels of nonperforming and other classified loans. The amount of the allowance is based on estimates and the ultimate losses may vary from the estimates as more information becomes available or events change.
	The Company provides for loan losses based on the allowance method. Accordingly, all loan losses are charged to the related allowance and all recoveries are credited to it. Additions to the allowance for loan losses are provided by charges to income based on various factors that, in our judgment, deserve current recognition in estimating probable incurred credit losses. The Company reviews the loan portfolio on an ongoing basis and makes provisions for loan losses on a quarterly basis to maintain the allowance for loan losses in accordance with GAAP. The allowance for loan losses consists of two components:
	•	specific allowances established for any impaired residential non-owner occupied mortgage, multi-family mortgage, nonresidential real estate, construction and land, commercial, and commercial lease loans for which the recorded investment in the loan exceeds the measured value of the loan; and
	•	general allowances for loan losses for each loan class based on historical loan loss experience; and adjustments to historical loss experience (general allowances), maintained to cover uncertainties that affect our estimate of probable incurred credit losses for each loan class. If the remaining unamortized discount related to a specific pool of purchased performing loans exceeds the estimated credit losses associated with these loans, no general valuation allowance is recorded against the loans.
	The adjustments to historical loss experience are based on our evaluation of several factors, including levels of, and trends in, past due and classified loans; levels of, and trends in, charge–offs and recoveries; trends in volume and terms of loans, including any credit concentrations in the loan portfolio; experience and ability of lending management and other relevant staff; and national and local economic trends and conditions.
	The Company evaluates the allowance for loan losses based upon the combined total of the specific and general components. Generally, when the loan portfolio increases, absent other factors, the allowance for loan loss methodology results in a higher dollar amount of estimated probable incurred credit losses than would be the case without the increase. Conversely, when the loan portfolio decreases, absent other factors, the allowance for loan loss methodology generally results in a lower dollar amount of estimated probable losses than would be the case without the decrease.
	The loss ratio used in computing the required general loan loss reserve allowance for a given class of loan consists of (i) the actual loss ratio (measured on a weighted, rolling twelve-quarter basis), (ii) the change in credit quality within the specific loan class during the period, (iii) the actual inherent risk factor assigned to the specific loan class and (iv) the actual concentration of risk factor assigned to the specific loan class (collectively, “the Specific Loan Class Risk Factors”). The Specific Loan Class Risk Factors are weighted equally in the calculation. In addition, two additional quantitative factors, the National Economic risk factor and the Local Economic risk factor, are also components of the computation but are given different weightings in their computation due to their relative applicability to the specific loan class in the context of the effect of national and local economic conditions on their risk profile and performance.
Uncollected Interest, Policy [Policy Text Block]	'
	Except for purchased impaired loans, when a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.
Mortgage Servicing Rights	'
	Mortgage Servicing Rights: Mortgage servicing rights are recognized separately when they are acquired through sales of loans. When mortgage loans are sold, servicing rights are initially recorded at fair value and gains on sales of loans are recorded in the statement of operations. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. The Company compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. All classes of servicing assets are subsequently measured using the amortization method which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans.
	Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with amortization and impairment of servicing assets on the statement of operations. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
	Servicing fee income that is reported on the statement of operations as loan servicing fees is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal; or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees related to loan servicing are not material.
Other Real Estate Owned	'
	Other Real Estate Owned: Real estate properties acquired in collection of a loan are initially recorded at fair value less cost to sell at acquisition, establishing a new cost basis. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating expenses, gains and losses on disposition, and changes in the valuation allowance are reported in noninterest expense as operations of other real estate owned ("OREO").
Premises and Equipment	'
	Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is included in noninterest expense and is computed on the straight-line method over the estimated useful lives of the assets. Useful lives are estimated to be 25 to 40 years for buildings and improvements that extend the life of the original building, ten to 20 years for routine building improvements, five to 15 years for furniture and equipment, two to five years for computer hardware and software and no greater than four years on automobiles. The cost of maintenance and repairs is charged to expense as incurred and significant repairs are capitalized.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets: Goodwill represents the excess of cost over the fair value of the net assets of businesses acquired. Goodwill and other intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but instead tested for impairment at least annually. The Company has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. The annual impairment analysis of goodwill includes identification of reporting units, the determination of the carrying value of each reporting unit, including the existing goodwill and intangible assets, and estimating the fair value of each reporting unit. The Company identified one significant reporting unit—banking operations. The Company determined the fair value of our reporting unit and compared it to its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, we are required to perform a second step to the impairment test.
	Our annual impairment analysis as of December 31, 2011, indicated that the step two analysis was necessary. It was determined that the implied value of goodwill was less than the carrying amount, and the Company reduced the full carrying amount of goodwill with a charge to earnings.
	Core deposit intangible assets (“CDI”), are recognized apart from goodwill at the time of acquisition based on valuations prepared by independent third parties or other estimates of fair value. In preparing such valuations, variables such as deposit servicing costs, attrition rates, and market discount rates are considered. CDI assets are amortized to expense over their useful lives.
Bank Owned Life Insurance	'
	Bank Owned Life Insurance: The Company has purchased life insurance policies on certain key executives. The Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Long-Term Assets	'
	Long-Term Assets: Premises and equipment, core deposit and other intangible assets, and other long-term assets are reviewed for impairment when events indicate that their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Loan Commitments and Related Financial Instruments	'
	Loan Commitments and Related Financial Instruments: Financial instruments include off-balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Income Taxes	'
	Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Under GAAP, a deferred tax asset valuation allowance is required to be recognized if it is “more likely than not” that the deferred tax asset will not be realized. The determination of the realizability of the deferred tax assets is highly subjective and dependent upon judgment concerning management’s evaluation of both positive and negative evidence, the forecasts of future taxable income, applicable tax planning strategies, and assessments of current and future economic and business conditions. The Company considers both positive and negative evidence regarding the ultimate realizability of our deferred tax assets. Examples of positive evidence may include the existence, if any, of taxes paid in available carry-back years and the likelihood that taxable income will be generated in future periods. Examples of negative evidence may include a cumulative loss in the current year and prior two years and negative general business and economic trends. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period of the enactment date.
	Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the amount of taxes paid in available carry-back years, the forecasts of future income, taking into account applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. At December 31, 2013 and 2012, after considering both positive and negative evidence, the Company determined that a full valuation allowance for deferred tax assets was required.
Retirement Plans	'
	Retirement Plans: Employee 401(k) and profit sharing plan expense is the amount of matching contributions and any annual discretionary contribution made at the discretion of the Company’s Board of Directors. Deferred compensation expense allocates the benefits over years of service.
Employee Stock Ownership Plan (ESOP)	'
	Employee Stock Ownership Plan (“ESOP”): The cost of shares issued to the ESOP, but not yet allocated to participants, is shown as a reduction of stockholders’ equity. Compensation expense is based on the market price of shares as they are committed to be released to participant accounts. Dividends on allocated ESOP shares reduce retained earnings; dividends on unearned ESOP shares reduce debt and accrued interest.
Earnings (Loss) Per Common Share	'
	Earnings (Loss) Per Common Share: Basic earnings (loss) per common share is net income (loss) divided by the weighted average number of common shares outstanding during the period. ESOP shares are considered outstanding for this calculation unless unearned. Diluted earnings (loss) per common share is net income (loss) divided by the weighted average number of common shares outstanding during the period plus the dilutive effect of restricted stock shares and the additional potential shares issuable under stock options.
Loss Contingencies	'
	Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe that there are such matters that will have a material effect on the financial statements as of December 31, 2013.
Restrictions on Cash	'
	Restrictions on Cash: Cash on hand or on deposit with the Federal Reserve Bank which is required to meet regulatory reserve and clearing requirements, based on a percentage of deposits.
Fair Value of Financial Instruments	'
	Fair Values of Financial Instruments: Fair values of financial instruments are estimated using relevant market value information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss): Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities, which are also recognized as separate components of stockholders’ equity.
Stock-based Compensation	'
	Stock-based Compensation: Compensation cost is recognized for stock options and restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. The Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period.
Transfers of Financial Assets	'
	Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, 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 the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Operating Segments	'
	Operating Segments: While management monitors the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Operating results are not reviewed by senior management to make resource allocation or performance decisions. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassifications	'
	Reclassifications: Certain reclassifications have been made in the prior year’s financial statements to conform to the current year’s presentation.

Uncollected Interest, Policy [Policy Text Block]	'
	Except for purchased impaired loans, when a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.
