Accounting Policies [Abstract]
Organization and Significant Accounting Policies	-1	Organization and Significant Accounting Policies
	Organization. Sunshine Bancorp, Inc., a Maryland corporation (the “Holding Company”), was formed on March 7, 2014 to serve as the savings and loan holding company for Sunshine Bank (the “Bank”). The Holding Company was formed as part of the Bank’s mutual-to-stock conversion (the “Conversion”). Collectively, the Bank and Holding Company are referred to as the “Company.”
	On July 14, 2014, the Conversion was completed and the Holding Company became the parent holding company for the Bank. A total of 4,232,000 shares of common stock were sold to depositors and the employee stock ownership plan (“ESOP”) at $10.00 per share through which the Holding Company received gross offering proceeds of approximately $42.3 million. The net proceeds received were $37.4 million after offering costs and the allocation of unearned ESOP shares. The Holding Company owns all the outstanding shares of common stock of the bank.
	The conversion was accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result.
	In connection with the Conversion, the Holding Company implemented an ESOP, to provide eligible employees the opportunity to own the Company’s stock. This plan is a tax-qualified retirement plan for the benefit of all Bank employees. A total of 338,560 shares of the stock issued in the conversion were acquired by the ESOP.
	The Bank through its five banking offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough and Pasco Counties, Florida. The Bank’s deposits are insured up to the applicable limits by the Federal Deposit Insurance Corporation (“FDIC”).
	As part of the Conversion, the Holding Company established a liquidation account in an amount equal to retained income of $26.6 million described in the final prospectus. The liquidation account will be maintained for the benefit of eligible account holders who maintain deposit accounts in the Bank after the conversion.
	Agreement to Acquire Certain Assets and Liabilities of Community Southern Holdings, Inc. On February 4, 2015, the Company signed an Agreement and Plan of Merger to acquire Community Southern Holdings, Inc. and the subsidiary Community Southern Bank in Lakeland, Florida. The Company will acquire approximately $246 million in assets and four branch locations in the Lakeland, Florida market. The transaction is subject to regulatory approval, is expected to close in the third quarter of 2015.
	Basis of Presentation. The accompanying consolidated financial statements include the accounts of the Holding Company and the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. The accounting and reporting practices of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and to general practices within the banking industry. The following summarizes the more significant of these policies and practices.
	Use of Estimates. In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of other real estate owned and deferred income taxes.
	Cash and Cash Equivalents. For purposes of the statements of cash flows, cash and cash equivalents include cash and balances due from banks, interest-bearing deposits with banks and federal funds sold, all of which have original maturities of ninety days or less.
	The Bank is required under Federal Reserve Board regulations to maintain cash reserves, generally consisting of deposits with the Federal Reserve Bank, of cash or noninterest-earning accounts with qualifying banks, against its transaction accounts. At December 31, 2014 and 2013, the Bank’s cash reserve requirements were $1,883,000 and $1,214,000, respectively.
	Securities Held to Maturity. Securities classified as held to maturity for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
	Loans Held for Sale. Loans held for sale includes loans originated which are intended for sale in
	the secondary market and substandard loans transferred to loans held for sale and are carried at the lower of book value or estimated fair value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to operations. At December 31, 2014 and 2013, the fair value of loans held for sale exceeded book value in the aggregate and were charged down to the fair value. In January 2015, $1.8 million in substandard loans held for sale were sold for $1.8 million resulting in a gain of $16,000.
	Loans. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal adjusted for any charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans.
	Loan origination fees are deferred and certain direct origination costs are capitalized. The net amount are deferred and are recognized as an adjustment of the yield of the related loan.
	The accrual of interest on all portfolio classes, including troubled debt restructurings, is discontinued at the time the loan is more than ninety-days delinquent unless the loan is well collateralized and in process of collection. Nonaccrual loans are reviewed for charge-off if more than ninety-days past due, except for residential loans and consumer loans. Residential loans are reviewed at 180 days and consumer loans are reviewed at 120 days past due. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered unlikely.
	All interest accrued but not collected for loans placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. In addition, a loan should be in accordance with the contractual terms for a reasonable period of time, usually requiring a payment history of six months.
	Allowance for Loan Losses. The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to operations. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. There were no changes in the Bank’s accounting policies or methodology related to the allowance for loan losses during the years ended December 31, 2014 or 2013.
	The allowance for loan losses is evaluated on a quarterly basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the size and composition of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
	The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans, an allowance is established when the discounted cash flows, collateral value or observable market price of the impaired loan is lower than the carrying value of that loan. The general component covers all other loans and is based on historical loss experience adjusted for qualitative factors.
	The historical loss component of the allowance is determined by losses recognized by portfolio segment over the preceding twenty quarters. This is supplemented by the risks for each portfolio segment. Risk factors impacting loans in each of the portfolio segments include broad deterioration of property values, reduced consumer and business spending as a result of unemployment and reduced credit availability and lack of confidence in the economy. The historical experience is adjusted for the following qualitative factors: (a) the existence and effect of any concentrations of credit and changes in the level of such concentrations; (b) changes in national, regional and local economic conditions that affect the collectability of the loan portfolio; (c) changes in levels or trends in charge-offs and recoveries; (d) changes in the volume and severity of past due loans, nonaccrual loans or loans classified special mention, substandard, doubtful or loss; (e) changes in the nature and volume of the loan portfolio and terms of loans; (f) changes in lending policies and procedures, risk selection and underwriting standards; (g) changes in the experience, ability and depth of lending management and other relevant staff; (h) quality of loan review; (i) the effect of other external factors, trends or uncertainties that could affect management’s estimate of probable losses, such as competition and industry conditions.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial, commercial real estate and residential mortgage loan segments by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent.
	Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer loans for impairment disclosures.
	Income Taxes. There are two components of income taxes: current and deferred. Current income taxes reflect taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income taxes result from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.
	Uncertain tax positions are recognized if it is more likely than not that the tax position will be realized or sustained upon examination including resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. As of December 31, 2014, management is not aware of any uncertain tax positions that would have a material effect on the Company’s financial statements.
	The Company recognizes interest and penalties on income taxes as a component of income taxes.
	Premises and Equipment. Land is stated at cost. Buildings and improvements and furniture and equipment are stated at cost, less accumulated depreciation. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Estimate useful lives for building and improvements is forty years; for furniture and equipment from three to ten years.
	Other Real Estate Owned. Other real estate owned includes assets acquired through, or in lieu of, loan foreclosure and are held for sale and are initially recorded at fair value less estimated selling costs at the date of foreclosure establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of the new cost basis or fair value less estimated selling costs. Revenue and expenses from operations and changes in the valuation allowance are included in operations.
	Fair Value Measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an 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. GAAP has established a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy describes three levels of inputs that may be used to measure fair value:
	Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities that are not active; and model-driven valuations whose inputs are observable or whose significant value drivers are observable. Valuations may be obtained from, or corroborated by, third-party pricing services.
	Level 3: Unobservable inputs to measure fair value of assets and liabilities for which there is little, if any market activity at the measurement date, using reasonable inputs and assumptions based upon the best information at the time, to the extent that inputs are available without undue cost and effort.
	The following describes valuation methodologies used for assets measured at fair value:
	Impaired Loans. Estimates of fair value for impaired loans is based on the estimated value of the underlying collateral which is determined based on a variety of information, including the use of available appraisals, estimates of market value by licensed appraisers or local real estate brokers and the knowledge and experience of the Company’s management related to values of properties in the Company’s market areas. Management takes into consideration the type, location and occupancy of the property as well as current economic conditions in the area the property is located in assessing estimates of fair value. Accordingly, fair value estimates for impaired loans are classified as Level 3.
	Foreclosed Assets. Estimates of fair values are determined based on a variety of information, including the use of available appraisals, estimates of market value by licensed appraisers or local real estate brokers and the knowledge and experience of the Company’s senior lending officers related to values of properties in the Company’s market areas. These officers take into consideration the type, location and occupancy of the property as well as current economic conditions in the area the property is located in assessing estimates of fair value. Accordingly, the fair values estimates for foreclosed real estate are classified as Level 3.
	Off-Balance-Sheet Financial Instruments. In the ordinary course of business the Company has entered into off-balance-sheet financial instruments consisting of unused lines of credit, commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded.
	Fair Values of Financial Instruments. The following methods and assumptions were used by the Company in estimating fair values of financial instruments:
	Cash and Cash Equivalents. The carrying amounts approximate their fair value.
	Time Deposits with Banks. The fair value of time deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits.
	Securities Held to Maturity. Fair values for securities are based on quoted market prices for identical or similar securities.
	Loans. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values are based on carrying values. Fair values for fixed-rate mortgages (e.g. one-to four-family residential), commercial real estate and commercial loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for nonperforming loans are estimated using discounted cash flow analysis or underlying collateral values, where applicable.
	Federal Home Loan Bank Stock. The stock is not publicly traded and the estimated fair value is its redemption value.
	Accrued Interest Receivable. The carrying amount of accrued interest receivable approximates its fair value.
	Deposit. The fair values disclosed for demand, NOW, money-market and savings deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). Fair values for fixed-rate time deposits are estimated using discounted cash flow calculation that applies interest rates currently being offering on time deposits to a schedule of aggregated expected monthly maturities of time deposits.
	Off-Balance-Sheet Financial Instruments. Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.
	Comprehensive Income (Loss). During the years ending December 31, 2014 and 2013, the Company had no components of other comprehensive income (loss).
	(Loss) Income Per Share. The conversion was complete on July 14, 2014. (Loss) Income per share will be computed starting on January 1, 2015, as if conversion from a mutual holding company to a capital stock holding company occurred on that date.
	Recent Accounting Standards Update. In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, which is intended to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additional disclosures are required. The amendments are effective beginning January 1, 2015. Upon adoption, this guidance is not expected to impact the Company’s consolidated financial statements.
	Recent Regulatory Developments
	Basel III Rules On July 2, 2013, the Federal Reserve Board (“FRB”) approved the final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks. Under the final rules, minimum requirements will increase for both the quantity and quality of capital held by the Bank. The rules include a new common equity Tier 1 capital to risk-weighted assets ratio of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets. The final rules also raise the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% and require a minimum leverage ratio of 4.0%. The final rules also implement strict eligibility criteria for regulatory capital instruments. In July 2013, the Office of the Comptroller of the Currency (“OCC”), our primary bank regulator, also approved, as an interim final rule, the regulatory capital requirements for U.S. banks, following the actions of the FRB. The OCC’s rule is identical in substance to the final rules issued by the FRB.
	The phase-in period for the final rules began for the Holding Company and the Bank on January 1, 2015, with full compliance with all of the final rule’s requirements phased in over a multi-year schedule.
	Reclassifications. Certain amounts in the 2013 financial statements have been reclassified to conform with the 2014 presentation.

	At December 31, 2014, the unrealized losses on seventeen investment securities held-to-maturity were caused by market conditions. It is expected that the securities would not be settled at a price less than the par value of the investments. Because the decline in fair value is attributable to market conditions and not credit quality, and because the Company has the ability and intent to hold these investments until a market price recovery or maturity, these investments are not considered other-than-temporarily impaired.
	On March 19, 2015 management transferred all securities classified as held to maturity to available for sale at an estimated fair market value of $69.8 million. The transfer was performed to enhance the interest rate risk position of the bank and provide liquidity for future loan growth. As a result of the transfer, the Bank is precluded from classifying securities as held to maturity until March 2017

	Loans, net		$	108,666			111,263
	The Company has divided the loan portfolio into three portfolio segments, each with different risk characteristics and methodologies for assessing risk. All loans are underwritten in accordance with policies set forth and approved by the Company’s Board of Directors. The portfolio segments identified by the Company are as follows:
	Real Estate Mortgage Loans. Real estate mortgage loans are typically segmented into four classes: one-to four-family residential, commercial, multi-family and land and construction.
	One-to four-family residential real loans are underwritten based on repayment capacity and source, value of the underlying property, credit history and stability.
	Commercial loans are secured by the subject property and are underwritten based on loan to value limits, cash flow coverage and general creditworthiness of the obligors.
	Multi-family loans follow the same underwriting criteria as commercial real estate loans. These loans are generally considered to have more credit risk than traditional one-to four-family residential loans because these loans tend to involve larger loan balances and their repayment is typically dependent upon the successful operation and management of the underlying real estate.
	Land and construction loans are to finance the construction of owner-occupied and lease properties. These loans are categorized as construction loans during the construction period, later converting to commercial or one-to four-family residential loans after the construction is complete and amortization of the loan begins. Real estate development and construction loans are approved based on an analysis of the borrower and guarantor, the viability of the project and on an acceptable percentage of the appraised value of the property securing the loan. Real estate development and construction loan funds are disbursed periodically based on the percentage of construction completed. The Company carefully monitors these loans with on-site inspections and requires the receipt of lien waivers on funds advanced. Development and construction loans are typically secured by the properties under development or construction, and personal guarantees are typically obtained. Further, to assure that reliance is not placed solely on the value of the underlying property, the Company considers the market conditions and feasibility of proposed projects, the financial condition and reputation of the borrower and guarantors, the amount of the borrower’s equity in the project, independent appraisals, cost estimates and pre-construction sale information. The Company also makes loans on occasion for the purchase of land for future development by the borrower. Land loans are extended for the future development for either commercial or residential use by the borrower. The Company carefully analyzes the intended use of the property and the viability thereof.
	Commercial Loans. Commercial loans are primarily underwritten on the basis of the borrowers’ ability to service such debt from income. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. As a general practice, the Company takes as collateral a security interest in any equipment, or other chattel, although loans may also be made on an unsecured basis. Collateralized working capital loans typically are secured by short-term assets whereas long-term loans are primarily secured by long-term assets.
	Consumer Loans. Consumer loans are extended for various purposes, including purchases of automobiles, recreational vehicles, and boats. The Company also offers lines of credit, personal loans, and deposit account collateralized loans. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Loans to consumers are extended after a credit evaluation, including the creditworthiness of the borrower(s), the purpose of the credit, and the secondary source of repayment. Consumer loans are made at fixed and variable interest rates and may be made on terms of up to ten years. Risk is mitigated by the fact that the loans are of smaller individual amounts.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors.
The Company analyzes loans individually by classifying the loans as to credit risk. Loans classified as substandard or special mention are reviewed quarterly by the Company for further deterioration or improvement to determine if they are appropriately classified and whether there is any impairment. All loans are graded upon initial issuance. Further, commercial, multi-family and commercial real estate loans over $25,000 are typically reviewed at least annually to determine the appropriate loan grading. In addition, during the renewal process of any loan, as well as if a loan becomes past due, the Company will determine the appropriate loan grade.
Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of a deterioration in the credit worthiness of the borrower; or (c) the borrower contacts the Company for a modification. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard or even charged-off. The Company uses the following definitions for risk ratings:
Pass – A Pass loan’s primary source of loan repayment is satisfactory, with secondary sources very likely to be realized if necessary.
Special Mention – A Special Mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or the Company’s credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.
Substandard – A Substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful – A loan classified Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristics that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
Loss – A loan classified Loss is considered uncollectible and of such little value that continuance as a bankable asset is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.

The allowance for loan losses on all loans that have been restructured and are considered TDRs is included in the Company’s specific allowance for loan losses. The specific allowance for loan losses is determined on a loan by loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, or the fair value of the collateral if the loan is collateral-dependent. TDR’s that have subsequently defaulted are considered collateral-dependent.
There were no TDRs which were restructured during the years ended December 31, 2014 and 2013 that subsequently defaulted.
Impaired collateral-dependent loans are carried at the lower of carrying value or fair value. Those impaired collateral-dependent loans which are measured at fair value or a nonrecurring basis are as follows (in thousands):

Off-Balance-Sheet Financial Instruments	-8	Off-Balance-Sheet Financial Instruments
	The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments are unused lines of credit, commitments to extend credit and standby letters of credit and may involve, to varying degrees, elements of credit and interest-rate risk in excess of the amount recognized in the balance sheets. The contract amounts of these instruments reflect the extent of involvement the Company has in these financial instruments.
	The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for unused lines of credit, commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments.
	Commitments to extend credit and unused lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some 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 credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company upon extension of credit is based on management’s credit evaluation of the counterparty.
	Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party and to support public and private borrowing arrangements. Essentially all letters of credit issued have expiration dates within one year. The credit risk involved in issuing letters-of-credit is essentially the same as that involved in extending loan facilities to customers. The Company may hold collateral supporting these commitments, and at December 31, 2014 such collateral amounted to approximately $188,000.
	Unused lines of credit, commitments to extend credit and standby letters of credit typically result in loans with a market interest rate when funded. A summary of the amounts of the Company’s financial instruments, with off-balance-sheet risk at December 31, 2014 follows (in thousands):
			Contract

	At December 31, 2014, the Company has Florida net operating loss carryforwards of approximately $4.6 million available to offset future taxable income. These carryforwards will begin to expire in 2033.
	The Company performs periodic evaluations on the deferred tax asset to determine if a valuation allowance is necessary. The analysis weighs positive evidence against negative evidence to determine if it is more likely than not to recognize the future benefit of the deferred tax asset. The Company’s analysis includes internal forecasts that demonstrate the Company’s ability to fully utilize the deferred tax asset prior to the expiration of the related net operating loss periods discussed above. The Company was profitable during 2013. The Company’s internal forecasts include growth assumptions relating to loans, noninterest income and noninterest expense, as well as estimating loan losses and other nonrecurring items. Management determined that a valuation allowance against the deferred tax asset was not necessary at December 31, 2014 or 2013.
	The Company files income tax returns in the U.S. federal jurisdiction and the State of Florida. The Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years before 2011.

	The Bank is subject to various regulatory capital requirement administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
	Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts (set forth in the table below) of total and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined). Management believes, as of December 31, 2014, that the Bank meets all capital adequacy requirements to which it is subject.
	As of December 31, 2014, the bank is categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the institution’s category. The Bank’s actual regulatory capital amounts and percentages are presented in the table ($ in thousands).

Organization_and_Significant_A1

Organization and Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Organization	Organization. Sunshine Bancorp, Inc., a Maryland corporation (the “Holding Company”), was formed on March 7, 2014 to serve as the savings and loan holding company for Sunshine Bank (the “Bank”). The Holding Company was formed as part of the Bank’s mutual-to-stock conversion (the “Conversion”). Collectively, the Bank and Holding Company are referred to as the “Company.”
	On July 14, 2014, the Conversion was completed and the Holding Company became the parent holding company for the Bank. A total of 4,232,000 shares of common stock were sold to depositors and the employee stock ownership plan (“ESOP”) at $10.00 per share through which the Holding Company received gross offering proceeds of approximately $42.3 million. The net proceeds received were $37.4 million after offering costs and the allocation of unearned ESOP shares. The Holding Company owns all the outstanding shares of common stock of the bank.
	The conversion was accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result.
	In connection with the Conversion, the Holding Company implemented an ESOP, to provide eligible employees the opportunity to own the Company’s stock. This plan is a tax-qualified retirement plan for the benefit of all Bank employees. A total of 338,560 shares of the stock issued in the conversion were acquired by the ESOP.
	The Bank through its five banking offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough and Pasco Counties, Florida. The Bank’s deposits are insured up to the applicable limits by the Federal Deposit Insurance Corporation (“FDIC”).
	As part of the Conversion, the Holding Company established a liquidation account in an amount equal to retained income of $26.6 million described in the final prospectus. The liquidation account will be maintained for the benefit of eligible account holders who maintain deposit accounts in the Bank after the conversion.
Agreement to Acquire Certain Assets and Liabilities of Community Southern Holdings, Inc	Agreement to Acquire Certain Assets and Liabilities of Community Southern Holdings, Inc. On February 4, 2015, the Company signed an Agreement and Plan of Merger to acquire Community Southern Holdings, Inc. and the subsidiary Community Southern Bank in Lakeland, Florida. The Company will acquire approximately $246 million in assets and four branch locations in the Lakeland, Florida market. The transaction is subject to regulatory approval, is expected to close in the third quarter of 2015.
Basis of Presentation	Basis of Presentation. The accompanying consolidated financial statements include the accounts of the Holding Company and the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. The accounting and reporting practices of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and to general practices within the banking industry. The following summarizes the more significant of these policies and practices.
Use of Estimates	Use of Estimates. In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of other real estate owned and deferred income taxes.
Cash and Cash Equivalents	Cash and Cash Equivalents. For purposes of the statements of cash flows, cash and cash equivalents include cash and balances due from banks, interest-bearing deposits with banks and federal funds sold, all of which have original maturities of ninety days or less.
	The Bank is required under Federal Reserve Board regulations to maintain cash reserves, generally consisting of deposits with the Federal Reserve Bank, of cash or noninterest-earning accounts with qualifying banks, against its transaction accounts. At December 31, 2014 and 2013, the Bank’s cash reserve requirements were $1,883,000 and $1,214,000, respectively.
Securities Held to Maturity	Securities Held to Maturity. Securities classified as held to maturity for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
Loans Held for Sale	Loans Held for Sale. Loans held for sale includes loans originated which are intended for sale in
	the secondary market and substandard loans transferred to loans held for sale and are carried at the lower of book value or estimated fair value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to operations. At December 31, 2014 and 2013, the fair value of loans held for sale exceeded book value in the aggregate and were charged down to the fair value. In January 2015, $1.8 million in substandard loans held for sale were sold for $1.8 million resulting in a gain of $16,000.
Loans	Loans. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal adjusted for any charge-offs, the allowance for loan losses, and any deferred fees or costs on originated loans.
	Loan origination fees are deferred and certain direct origination costs are capitalized. The net amount are deferred and are recognized as an adjustment of the yield of the related loan.
	The accrual of interest on all portfolio classes, including troubled debt restructurings, is discontinued at the time the loan is more than ninety-days delinquent unless the loan is well collateralized and in process of collection. Nonaccrual loans are reviewed for charge-off if more than ninety-days past due, except for residential loans and consumer loans. Residential loans are reviewed at 180 days and consumer loans are reviewed at 120 days past due. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered unlikely.
	All interest accrued but not collected for loans placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. In addition, a loan should be in accordance with the contractual terms for a reasonable period of time, usually requiring a payment history of six months.
Allowance for Loan Losses	Allowance for Loan Losses. The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to operations. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. There were no changes in the Bank’s accounting policies or methodology related to the allowance for loan losses during the years ended December 31, 2014 or 2013.
	The allowance for loan losses is evaluated on a quarterly basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the size and composition of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
	The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired. For such loans, an allowance is established when the discounted cash flows, collateral value or observable market price of the impaired loan is lower than the carrying value of that loan. The general component covers all other loans and is based on historical loss experience adjusted for qualitative factors.
	The historical loss component of the allowance is determined by losses recognized by portfolio segment over the preceding twenty quarters. This is supplemented by the risks for each portfolio segment. Risk factors impacting loans in each of the portfolio segments include broad deterioration of property values, reduced consumer and business spending as a result of unemployment and reduced credit availability and lack of confidence in the economy. The historical experience is adjusted for the following qualitative factors: (a) the existence and effect of any concentrations of credit and changes in the level of such concentrations; (b) changes in national, regional and local economic conditions that affect the collectability of the loan portfolio; (c) changes in levels or trends in charge-offs and recoveries; (d) changes in the volume and severity of past due loans, nonaccrual loans or loans classified special mention, substandard, doubtful or loss; (e) changes in the nature and volume of the loan portfolio and terms of loans; (f) changes in lending policies and procedures, risk selection and underwriting standards; (g) changes in the experience, ability and depth of lending management and other relevant staff; (h) quality of loan review; (i) the effect of other external factors, trends or uncertainties that could affect management’s estimate of probable losses, such as competition and industry conditions.
	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial, commercial real estate and residential mortgage loan segments by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral-dependent.
	Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer loans for impairment disclosures.
Income Taxes	Income Taxes. There are two components of income taxes: current and deferred. Current income taxes reflect taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income taxes result from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.
	Uncertain tax positions are recognized if it is more likely than not that the tax position will be realized or sustained upon examination including resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. As of December 31, 2014, management is not aware of any uncertain tax positions that would have a material effect on the Company’s financial statements.
	The Company recognizes interest and penalties on income taxes as a component of income taxes.
Premises and Equipment	Premises and Equipment. Land is stated at cost. Buildings and improvements and furniture and equipment are stated at cost, less accumulated depreciation. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Estimate useful lives for building and improvements is forty years; for furniture and equipment from three to ten years.
Other Real Estate Owned	Other Real Estate Owned. Other real estate owned includes assets acquired through, or in lieu of, loan foreclosure and are held for sale and are initially recorded at fair value less estimated selling costs at the date of foreclosure establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of the new cost basis or fair value less estimated selling costs. Revenue and expenses from operations and changes in the valuation allowance are included in operations.
Fair Value Measurements	Fair Value Measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an 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. GAAP has established a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The hierarchy describes three levels of inputs that may be used to measure fair value:
	Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities that are not active; and model-driven valuations whose inputs are observable or whose significant value drivers are observable. Valuations may be obtained from, or corroborated by, third-party pricing services.
	Level 3: Unobservable inputs to measure fair value of assets and liabilities for which there is little, if any market activity at the measurement date, using reasonable inputs and assumptions based upon the best information at the time, to the extent that inputs are available without undue cost and effort.
	The following describes valuation methodologies used for assets measured at fair value:
	Impaired Loans. Estimates of fair value for impaired loans is based on the estimated value of the underlying collateral which is determined based on a variety of information, including the use of available appraisals, estimates of market value by licensed appraisers or local real estate brokers and the knowledge and experience of the Company’s management related to values of properties in the Company’s market areas. Management takes into consideration the type, location and occupancy of the property as well as current economic conditions in the area the property is located in assessing estimates of fair value. Accordingly, fair value estimates for impaired loans are classified as Level 3.
	Foreclosed Assets. Estimates of fair values are determined based on a variety of information, including the use of available appraisals, estimates of market value by licensed appraisers or local real estate brokers and the knowledge and experience of the Company’s senior lending officers related to values of properties in the Company’s market areas. These officers take into consideration the type, location and occupancy of the property as well as current economic conditions in the area the property is located in assessing estimates of fair value. Accordingly, the fair values estimates for foreclosed real estate are classified as Level 3.
Off-Balance-Sheet Financial Instruments	Off-Balance-Sheet Financial Instruments. In the ordinary course of business the Company has entered into off-balance-sheet financial instruments consisting of unused lines of credit, commitments to extend credit and standby letters of credit. Such financial instruments are recorded in the financial statements when they are funded.
Fair Values of Financial Instruments	Fair Values of Financial Instruments. The following methods and assumptions were used by the Company in estimating fair values of financial instruments:
	Cash and Cash Equivalents. The carrying amounts approximate their fair value.
	Time Deposits with Banks. The fair value of time deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits.
	Securities Held to Maturity. Fair values for securities are based on quoted market prices for identical or similar securities.
	Loans. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values are based on carrying values. Fair values for fixed-rate mortgages (e.g. one-to four-family residential), commercial real estate and commercial loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for nonperforming loans are estimated using discounted cash flow analysis or underlying collateral values, where applicable.
	Federal Home Loan Bank Stock. The stock is not publicly traded and the estimated fair value is its redemption value.
	Accrued Interest Receivable. The carrying amount of accrued interest receivable approximates its fair value.
	Deposit. The fair values disclosed for demand, NOW, money-market and savings deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). Fair values for fixed-rate time deposits are estimated using discounted cash flow calculation that applies interest rates currently being offering on time deposits to a schedule of aggregated expected monthly maturities of time deposits.
	Off-Balance-Sheet Financial Instruments. Fair values for off-balance-sheet lending commitments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.
Comprehensive Income (Loss)	Comprehensive Income (Loss). During the years ending December 31, 2014 and 2013, the Company had no components of other comprehensive income (loss).

Recent Accounting Standards Update	Recent Accounting Standards Update. In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure, which is intended to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure; or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additional disclosures are required. The amendments are effective beginning January 1, 2015. Upon adoption, this guidance is not expected to impact the Company’s consolidated financial statements.
