Organization	Organization
	Green Dot Corporation (“we,” “us” and “our” refer to Green Dot Corporation and its wholly-owned subsidiaries) is a pro-consumer technology innovator with a mission to reinvent personal banking for the masses. Our products and services include: Green Dot MasterCard and Visa-branded prepaid debit cards and several co-branded reloadable prepaid card programs, collectively referred to as our GPR cards; Visa-branded gift cards; checking account products, such as GoBank, an innovative checking account developed for use via mobile phones that is available at Walmart and online; our swipe reload and MoneyPak proprietary products, collectively referred to as our cash transfer products, which enable cash loading and transfer services through our Green Dot Network; and tax refund processing services designed to facilitate the secure receipt of funds claimed by a taxpayer as a refund on a taxpayer's tax return.
	Our products and services are available to consumers through a large-scale "branchless bank" distribution network of more than 100,000 U.S. locations, including retailers, neighborhood financial service center locations and tax preparation offices, as well as online, in the leading app stores and through leading online tax preparation providers. The Green Dot Network enables consumers to use cash to reload our prepaid debit cards or to transfer cash to any of our Green Dot Network acceptance members, including competing prepaid card programs and other online accounts. We are also the tax refund processing service provider for four out of the six leading consumer online and in-person tax preparation companies.
	We market our products and services to banked, underbanked and unbanked consumers in the United States. We use distribution channels other than traditional bank branches to market our GPR cards, checking accounts and cash transfer services, such as third-party retailer locations nationwide, financial service centers, and the Internet. Our prepaid debit cards are issued by our wholly-owned subsidiary, Green Dot Bank and third-party issuing banks including The Bancorp Bank and Sunrise Banks, N.A. We also have multi-year distribution arrangements with many large and medium-sized retailers, such as Walgreens, CVS, Rite Aid, 7-Eleven, Kroger, Kmart, and Dollar Tree, and with various industry resellers, such as Blackhawk Network and Incomm. We currently have a one year contract with Walmart, pending the outcome of our proposal for renewal. We refer to participating retailers collectively as our “retail distributors.” Our tax refund processing services are integrated into the offerings of the nation’s leading tax software companies, which, together, enable us to serve approximately 25,000 independent online and in-person tax preparers and accountants nationwide.
	In January 2015, we completed the acquisition of AccountNow, Inc. We issued approximately 514,000 shares of our Class A common stock on the date of close and the remainder of the consideration was paid in cash. AccountNow's results of operations are included in our consolidated statements of operations following the acquisition date. We have not presented pro-forma results of operations because the effect of this acquisition was not material to our financial results. Of the total consideration transferred, we made a preliminary allocation of $65.9 million and $16.1 million to goodwill and intangible assets, respectively.  We may adjust this allocation after obtaining more information regarding, among other things, asset valuations, liabilities assumed, and revisions of preliminary estimates. The purchase price allocation will be finalized in 2015.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions.
	We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2014 for additional disclosures, including a summary of our significant accounting policies. There have been no changes to our significant accounting policies during the three months ended March 31, 2015. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented.
	Recent Accounting Pronouncements
	In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05").  This ASU provides guidance to customers about whether a cloud computing
	Note 2—Summary of Significant Accounting Policies (continued)
	arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer's accounting for service contracts. ASU 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. We are currently evaluating the provisions of the ASU to determine the potential impact the new standard will have on our consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03") which changes the presentation of debt issuance costs in financial statements. ASU 2015-03 requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The ASU is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. The new guidance will be applied retrospectively to each prior period presented. We are currently in the process of evaluating the impact of adoption of the ASU on our consolidated balance sheets.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP.
	The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The FASB recently issued a proposal to extend the effective date by one year. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.

We do not intend to sell these investments and we have determined that it is more likely than not that we will not be required to sell these investments before recovery of their amortized cost bases, which may be at maturity.
	As of March 31, 2015, the contractual maturities of our available-for-sale investment securities were as follows:

	The expected payments on mortgage-backed and asset-backed securities may not coincide with their contractual maturities because the issuers have the right to call or prepay certain obligations.

	Credit Quality Indicators
	We closely monitor and assess the credit quality and credit risk of our loan portfolio on an ongoing basis. We continuously review and update loan risk classifications. We evaluate our loans using non-classified or classified as the primary credit quality indicator. Classified loans are those loans that have demonstrated credit weakness where we believe there is a heightened risk of principal loss, including all impaired loans. Classified loans are generally internally categorized as substandard, doubtful or loss, consistent with regulatory guidelines.
	The table below presents the carrying value, gross of the related allowance for loan losses, of our loans within the primary credit quality indicators related to our loan portfolio:

	Impaired Loans and Troubled Debt Restructurings
	When, for economic or legal reasons related to a borrower’s financial difficulties, we grant a concession for other than an insignificant period of time to a borrower that we would not otherwise consider, the related loan is classified as a Troubled Debt Restructuring, or TDR. Our TDR modifications involve an extension of the maturity date at a stated interest rate lower than the current market rate for new debt with similar risk. The following table presents our impaired loans and loans that we modified as TDRs as of March 31, 2015 and December 31, 2014:

	Revolving facility	—		—
	Total notes payable	$	144,375	$	150,000
	In October 2014, we entered into a $225.0 million credit agreement with Bank of America, N.A., as an administrative agent, Wells Fargo Bank, National Association, and the other lenders party thereto. The credit agreement provides for 1) a $75.0 million five-year revolving facility (the "Revolving Facility") and 2) a five-year $150.0 million term loan facility ("Term Facility" and, together with the Revolving Facility, the “Senior Credit Facility). The credit agreement also includes an accordion feature that, subject to securing additional commitments from existing lenders or new lending institutions, will allow us to increase the aggregate amount of these facilities by up to an additional $50.0 million.
	Interest
	At our election, loans made under the credit agreement bear interest at 1) a LIBOR rate (the “LIBOR Rate") or 2) a base rate determined by reference to the highest of (a) the Bank of America prime rate, (b) the United States federal funds rate plus 0.50% and (c) a daily rate equal to one-month LIBOR rate plus1.0% (the “Base Rate"), plus in either case an applicable margin. The applicable margin for borrowings depends on our total leverage ratio and varies from 2.50% to 3.00% for LIBOR Rate loans and 1.50% to 2.00% for Base Rate loans. The effective interest rate on borrowings outstanding as of March 31, 2015 was 2.93%. Interest expense, excluding the amortization of debt issuance costs, related to our Senior Credit Facility was $1.2 million for the three months ended March 31, 2015.
	Covenants and restrictions
	The Senior Credit Facility contains customary representations and warranties relating to us and our subsidiaries. The Senior Credit Facility also contains certain affirmative and negative covenants including negative covenants that limit or restrict, among other things, liens, indebtedness, investments and acquisitions, mergers and fundamental changes, asset sales, restricted payments, changes in the nature of the business, transactions with affiliates and other matters customarily restricted in such agreements. We must maintain a minimum fixed charge coverage ratio and a maximum consolidated leverage ratio at the end of each fiscal quarter, as set forth in the credit agreement. At March 31, 2015, we were in compliance with all such covenants.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	Income tax expense for the three months ended March 31, 2015 and 2014 differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. The sources and tax effects of the differences are as follows:
		Three Months Ended March 31,
		2015		2014
	U.S. federal statutory tax rate	35	%	35	%
	State income taxes, net of federal tax benefit	2		1.8
	General business credits	(0.7	)	(1.5	)
	Employee stock-based compensation	0.7		1.4
	Other	1		1.1
	Effective tax rate	38	%	37.8	%
	The effective tax rate for the
	three months ended March 31, 2015 and 2014 differs from the statutory federal income tax rate of 35% primarily due to state income taxes, net of federal tax benefit, general business credits and non-deductible employee stock based compensation. The increase in the effective tax rates for the three months ended March 31, 2015 as compared to the three months ended March 31, 2014 is primarily attributable to the expiration of certain state business tax credit programs on December 31, 2013, that gradually decreases the business tax credits available to us over the next five years.
	We establish a valuation allowance when we consider it more-likely-than-not that some portion or all of the deferred tax assets will not be realized. As of March 31, 2015 and March 31, 2014, we did not have a valuation allowance on any of our deferred tax assets as we believed it was more-likely-than-not that we would realize the benefits of our deferred tax assets.
	We are subject to examination by the Internal Revenue Service, or IRS, and various state tax authorities. Our consolidated federal income tax returns for the five-months ended December 31, 2009 and the years ended December 31, 2010 and 2011 are currently under examination by the IRS. We remain subject to examination of our federal income tax return for the years ended December 31, 2012 and 2013. We generally remain subject to examination of our various state income tax returns for a period of four to five years from the respective dates the returns were filed.
	As of March 31, 2015, we have net operating loss carryforwards of approximately $46.8 million and $40.3 million for federal and state tax purposes, respectively, which will be available to offset future income. If not used, these carryforwards will expire between 2025 and 2034. In addition, we have state business tax credits of approximately $4.1 million that will expire between 2028 and 2034 and other state business tax credits of approximately $1.4 million that will expire 2024.
	As of March 31, 2015 and 2014, we had a liability of $6.9 million and $4.4 million, respectively, for unrecognized tax benefits related to various federal and state income tax matters excluding interest, penalties and related tax benefits. The reconciliation of the beginning unrecognized tax benefits balance to the ending balance is as follows:
		Three Months Ended March 31,
		2015			2014
		(In thousands)
	Beginning balance	$	6,190		$	3,724

	The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate	$	6,866		$	4,400
	We recognized accrued interest and penalties related to unrecognized tax benefits for the three months ended March 31, 2015 and 2014, of approximately $0.3 million and $0.3 million, respectively.

	Under applicable accounting guidance, 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.
	We determine the fair values of our financial instruments based on the fair value hierarchy established under applicable accounting guidance which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs used to measure fair value.
	For more information regarding the fair value hierarchy and how we measure fair value, see Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2014.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments
	The following describes the valuation technique for determining the fair value of financial instruments, whether or not such instruments are carried at fair value on our consolidated balance sheets.
	Short-term Financial Instruments
	Our short-term financial instruments consist principally of unrestricted and restricted cash and cash equivalents, federal funds sold, settlement assets and obligations, and obligations to customers. These financial instruments are short-term in nature, and, accordingly, we believe their carrying amounts approximate their fair values. Under the fair value hierarchy, these instruments are classified as Level 1.
	Investment Securities
	The fair values of investment securities have been derived using methodologies referenced in Note 2–Summary of Significant Accounting Policies to the Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended December 31, 2014. Under the fair value hierarchy, our investment securities are classified as Level 2. As of March 31, 2015, we had one investment classified as Level 3, which was not material to our investment portfolio.
	Loans
	We determined the fair values of loans by discounting both principal and interest cash flows expected to be collected using a discount rate commensurate with the risk that we believe a market participant would consider in determining fair value. Under the fair value hierarchy, our loans are classified as Level 3.
	Deposits
	The fair value of demand and interest checking deposits and savings deposits is the amount payable on demand at the reporting date. We determined the fair value of time deposits by discounting expected future cash flows using market-derived rates based on our market yields on certificates of deposit, by maturity, at the measurement date. Under the fair value hierarchy, our deposits are classified as Level 2.
	Contingent Consideration
	The fair value of contingent consideration obligations are estimated through valuation models designed to estimate the probability of such contingent payments based on various assumptions.  Estimated payments are discounted using present value techniques to arrive at an estimated fair value.  Our contingent consideration payable is classified as Level 3 because we use unobservable inputs to estimate fair value, including the probability of achieving certain earnings thresholds and appropriate discount rates. Changes in fair value of contingent consideration are recorded through operating expenses.
	Note Payable
	The fair value of our note payable is based on borrowing rates currently available to a market participant for loans with similar terms or maturity. The carrying amount of our note payable is considered a Level 2 liability and approximates fair value since the interest rate charged is variable and commensurate with rates presently available in the market.
	Fair Value of Financial Instruments
	The carrying values and fair values of certain financial instruments that were not carried at fair value, excluding short-term financial instruments for which the carrying value approximates fair value, at March 31, 2015 and December 31, 2014 are presented in the table below.

Commitments and Contingencies	Commitments and Contingencies
	We monitor the laws of all 50 states to identify state laws or regulations that apply (or may apply) to our products and services. We have obtained money transmitter licenses (or similar such licenses) where applicable, based on advice of counsel or when we have been requested to do so. If we were found to be in violation of any laws and regulations governing banking, money transmitters, electronic fund transfers, or money laundering in the United States or abroad, we could be subject to penalties or could be forced to change our business practices.
	In the ordinary course of business, we are a party to various legal proceedings. We review these actions on an ongoing basis to determine whether it is probable that a loss has occurred and use that information when making accrual and disclosure decisions. We have not established reserves or possible ranges of losses related to these proceedings because, at this time in the proceedings, the matters do not relate to a probable loss and/or the amounts are not reasonably estimable.
	From time to time we enter into contracts containing provisions that contingently require us to indemnify various parties against claims from third parties. These contracts primarily relate to: (i) contracts with our card issuing banks, under which we are responsible to them for any unrecovered overdrafts on cardholders’ accounts; (ii) certain real estate leases, under which we may be required to indemnify property owners for environmental and other liabilities, and other claims arising from our use of the premises; (iii) certain agreements with our officers, directors, and employees, under which we may be required to indemnify these persons for liabilities arising out of their relationship with us; and (iv) contracts under which we may be required to indemnify our retail distributors, suppliers, vendors and other parties with whom we have contracts against claims arising from certain of our actions, omissions, violations of law and/or infringement of patents, trademarks, copyrights and/or other intellectual property rights.
	Generally, a maximum obligation under these contracts is not explicitly stated. Because the obligated amounts associated with these types of agreements are not explicitly stated, the overall maximum amount of the obligation cannot be reasonably estimated. With the exception of overdrafts on cardholders’ accounts, historically, we have not been required to make payments under these and similar contingent obligations, and no liabilities have been recorded for these obligations in our consolidated balance sheets.
	For additional information regarding overdrafts on cardholders’ accounts, refer to Note 4 — Accounts Receivable.
	As of March 31, 2015 and December 31, 2014, we had $1.5 million outstanding in standby letters of credit related to our corporate facility lease.

	A credit concentration may exist if customers are involved in similar industries, economic sectors, and geographic regions. Our retail distributors operate in similar economic sectors but diverse domestic geographic regions. The loss of a significant retail distributor could have a material adverse effect upon our card sales, profitability, and revenue growth.
	Note 15—Significant Customer Concentration (continued)
	Revenues derived from our products sold at retail distributors constituting greater than 10% of our total operating revenues were as follows:

	Excluding stock-based retailer incentive compensation of $1.9 million and $2.4 million for the three months ended March 31, 2015 and 2014, respectively, revenues derived from our products sold at retail distributors constituting greater than 10% of our total operating revenues were as follows:
		Three Months Ended March 31,

Segment Reporting [Abstract]
Segment Information	Segment Information
	As of December 31, 2014, and prior, our operations were within one reportable segment. As a result of recent acquisitions occurring in late 2014 and early 2015, we have realigned our operations into two reportable segments: Account Services and Processing and Settlement Services. We identified our reportable segments based on factors such as how we manage our operations and how our chief operating decision maker views results. Our chief operating decision maker organizes and manages our business primarily on the basis of product and service offerings and uses operating income to assess profitability.
	The Account Services segment consists of revenues and expenses derived from our branded and private label deposit account programs. These programs include our Green Dot-branded and affinity-branded GPR card accounts, private label GPR card accounts, checking accounts and open-loop gift cards. The Processing and Settlement Services segment consists of revenues and expenses derived from reload services through the Green Dot Network and our tax refund processing services. The Corporate and Other segment primarily consists of unallocated corporate expenses, depreciation and amortization, intercompany eliminations and other costs that are not considered when management evaluates segment performance. We do not evaluate performance or allocate resources based on segment asset data, and therefore such information is not presented.
	Note 16—Segment Information (continued)
	The following table presents certain financial information for each of our reportable segments for the three months ended March 31, 2015. We have determined that it is impracticable to restate segment information for the three months ended March 31, 2014, as well as to provide disclosures under both the old basis and new basis of reporting for certain items. Therefore, no such disclosures are presented.

	The accompanying unaudited consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America, or GAAP. We consolidated our wholly-owned subsidiaries and eliminated all significant intercompany balances and transactions.
	We have also prepared the accompanying unaudited consolidated financial statements in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X and, consequently, they do not include all of the annual disclosures required by GAAP. Reference is made to our Annual Report on Form 10-K for the year ended December 31, 2014 for additional disclosures, including a summary of our significant accounting policies. There have been no changes to our significant accounting policies during the three months ended March 31, 2015. In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments, consisting of normal and recurring items, except as otherwise noted, necessary for the fair presentation of our financial position, results of operations and cash flows for the interim periods presented.
New Accounting Pronouncements	Recent Accounting Pronouncements
	In April 2015, the FASB issued ASU No. 2015-05, Customer's Accounting for Fees Paid in a Cloud Computing Arrangement ("ASU 2015-05").  This ASU provides guidance to customers about whether a cloud computing
	Note 2—Summary of Significant Accounting Policies (continued)
	arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer's accounting for service contracts. ASU 2015-05 is effective for interim and annual reporting periods beginning after December 15, 2015. We are currently evaluating the provisions of the ASU to determine the potential impact the new standard will have on our consolidated financial statements.
	In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03") which changes the presentation of debt issuance costs in financial statements. ASU 2015-03 requires an entity to present such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. The ASU is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. The new guidance will be applied retrospectively to each prior period presented. We are currently in the process of evaluating the impact of adoption of the ASU on our consolidated balance sheets.
	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP.
	The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The FASB recently issued a proposal to extend the effective date by one year. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.
