Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1—Summary of Significant Accounting Policies Organization. Visa Inc., together with its subsidiaries (Visa or the Company), is a global payments technology company that facilitates global commerce and money movement across more than 200 countries and territories. Visa operates one of the world’s largest electronic payments networks — VisaNet — which provides transaction processing services (primarily authorization, clearing and settlement). The Company offers products, solutions and services that facilitate secure, reliable and efficient money movement for participants in the ecosystem. Visa is not a financial institution and does not issue cards, extend credit or set rates and fees for account holders of Visa products. In most cases, account holder and merchant relationships belong to, and are managed by, Visa’s financial institution clients. Consolidation and basis of presentation. The accompanying unaudited consolidated financial statements include the accounts of Visa and its consolidated entities and are presented in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The Company consolidates its majority-owned and controlled entities, including variable interest entities (VIEs) for which the Company is the primary beneficiary. The Company’s investments in VIEs have not been material to its unaudited consolidated financial statements as of and for the periods presented. Intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with U.S. Securities and Exchange Commission (SEC) requirements for Quarterly Reports on Form 10-Q and, consequently, do not include all of the annual disclosures required by U.S. GAAP. Reference should be made to Visa’s Annual Report on Form 10-K for the year ended September 30, 2023 for additional disclosures, including a summary of the Company’s significant accounting policies. In the opinion of management, the accompanying unaudited consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results of operations for interim periods are not necessarily indicative of results for the full year. Use of estimates. The preparation of the accompanying unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and reported amounts of revenues and expenses during the reporting period. These estimates may change as new events occur and additional information is obtained, and will be recognized in the period in which such changes occur. Future actual results could differ materially from these estimates.

Acquisitions	Note 2—Acquisitions On January 16, 2024, Visa acquired Pismo Holdings, a global cloud-native issuer processing and core banking platform, for $1.0 billion in cash. Due to the limited amount of time since the acquisition date, the initial allocation of the purchase price is not yet complete. The Company expects to provide the initial purchase price allocation within its Form 10-Q for the second quarter of fiscal 2024.

The following tables disaggregate the Company’s net revenues by revenue category and by geography: Three Months Ended 2023 2022 (in millions) Service revenues $ 3,915 $ 3,511 Data processing revenues 4,356 3,827 International transaction revenues 3,019 2,797 Other revenues 692 587 Client incentives (3,348) (2,786) Net revenues $ 8,634 $ 7,936 Three Months Ended 2023 2022 (in millions) U.S. $ 3,645 $ 3,567 International 4,989 4,369 Net revenues $ 8,634 $ 7,936 Remaining performance obligations are comprised of deferred revenues and contract revenues that will be invoiced and recognized as revenues in future periods primarily related to value added services. As of December 31, 2023, the remaining performance obligations were $3.2 billion. The Company expects approximately half to be recognized as revenues in the next two years and the remaining thereafter. However, the amount and timing of revenue recognition is affected by several factors, including contract modifications and terminations, which could impact the estimate of amounts allocated to remaining performance obligations and when such revenues could be recognized.

Retrospective Responsibility Plans [Abstract]
U.S. and Europe Retrospective Responsibility Plans	Note 5—U.S. and Europe Retrospective Responsibility Plans U.S. Retrospective Responsibility Plan Under the terms of the U.S. retrospective responsibility plan, the Company maintains an escrow account from which settlements of, or judgments in, certain litigation (U.S. covered litigation) are paid. The accrual related to the U.S. covered litigation could be either higher or lower than the U.S. litigation escrow account balance. See Note 13—Legal Matters . The following table presents the changes in the restricted cash equivalents—U.S. litigation escrow account: Three Months Ended 2023 2022 (in millions) Balance as of beginning of period $ 1,764 $ 1,449 Deposits into the U.S. litigation escrow account — 350 Payments to opt-out merchants (1) , net of interest earned on escrow funds (148) (94) Balance as of end of period $ 1,616 $ 1,705 (1) These payments are associated with the interchange multidistrict litigation. See Note 13—Legal Matters . Europe Retrospective Responsibility Plan Visa Inc., Visa International and Visa Europe are parties to certain existing and potential litigation relating to the setting of multilateral interchange fee rates in the Visa Europe territory (VE territory covered litigation). Under the terms of the Europe retrospective responsibility plan, the Company is entitled to recover certain losses resulting from VE territory covered litigation (VE territory covered losses) through a periodic adjustment to the class A common stock conversion rates applicable to the series B and C preferred stock. VE territory covered losses are recorded in the contra-equity account right to recover for covered losses within stockholders’ equity before the corresponding adjustment to the applicable conversion rate is effected. Adjustments to the conversion rate may be executed once in any six-month period unless a single, individual loss greater than €20 million is incurred, in which case, the six-month limitation does not apply. When the adjustment to the conversion rate is made, the amount previously recorded in right to recover for covered losses is then recorded against the book value of the preferred stock within stockholders’ equity. The following table presents the activities related to VE territory covered losses in preferred stock and right to recover for covered losses within stockholders’ equity: Three Months Ended December 31, 2023 Preferred Stock Right to Recover for Covered Losses Series B Series C (in millions) Balance as of beginning of period $ 441 $ 801 $ (140) VE territory covered losses incurred (1) — — (24) Recovery through conversion rate adjustment (22) (3) 25 Balance as of end of period $ 419 $ 798 $ (139) Three Months Ended December 31, 2022 Preferred Stock Right to Recover for Covered Losses Series B Series C (in millions) Balance as of beginning of period $ 460 $ 812 $ (35) VE territory covered losses incurred (1) — — (8) Recovery through conversion rate adjustment (2) (7) (7) 15 Balance as of end of period $ 453 $ 805 $ (28) (1) VE territory covered losses incurred reflect settlements with merchants and additional legal costs. See Note 13—Legal Matters . (2) Adjustment to right to recover for covered losses for the conversion rate adjustment differs from the actual recovered amount due to differences in foreign exchange rates between the time the losses were incurred and the subsequent recovery through the conversion rate adjustment. The following table presents the as-converted value of the preferred stock available to recover VE territory covered losses compared to the book value of preferred stock recorded within the Company’s consolidated balance sheets: December 31, 2023 September 30, 2023 As-converted Value of Preferred Stock (1),(2) Book Value of Preferred Stock (1) As-converted Value of Preferred Stock (1),(3) Book Value of Preferred Stock (1) (in millions) Series B preferred stock $ 1,875 $ 419 $ 1,676 $ 441 Series C preferred stock 2,979 798 2,635 801 Total 4,854 1,217 4,311 1,242 Less: right to recover for covered losses (139) (139) (140) (140) Total recovery for covered losses available $ 4,715 $ 1,078 $ 4,171 $ 1,102 (1) Figures in the table may not recalculate exactly due to rounding. As-converted and book values are based on unrounded numbers. (2) As of December 31, 2023, the as-converted value of preferred stock is calculated as the product of: (a) 2 million and 3 million shares of the series B and C preferred stock outstanding, respectively; (b) 2.903 and 3.625, the class A common stock conversion rate applicable to the series B and C preferred stock outstanding, respectively; and (c) $260.35, Visa’s class A common stock closing stock price. (3) As of September 30, 2023, the as-converted value of preferred stock is calculated as the product of: (a) 2 million and 3 million shares of the series B and C preferred stock outstanding, respectively; (b) 2.937 and 3.629, the class A common stock conversion rate applicable to the series B and C preferred stock outstanding, respectively; and (c) $230.01, Visa’s class A common stock closing stock price.

Money market funds, U.S. Treasury securities and marketable equity securities are classified as Level 1 within the fair value hierarchy, as fair value is based on unadjusted quoted prices in active markets for identical assets. The Company’s deferred compensation liability is measured at fair value based on marketable equity securities held under the deferred compensation plan. Level 2 assets and liabilities. The fair value of U.S. government-sponsored debt securities, as provided by third-party pricing vendors, is based on quoted prices in active markets for similar, not identical, assets. Derivative instruments are valued using inputs that are observable in the market or can be derived principally from or corroborated by observable market data. U.S. Government-sponsored Debt Securities and U.S. Treasury Securities The amortized cost, unrealized gains and losses and fair value of debt securities were as follows: December 31, 2023 Amortized Gross Unrealized Fair Gains Losses (in millions) U.S. government-sponsored debt securities $ 1,607 $ 2 $ (1) $ 1,608 U.S. Treasury securities 5,956 19 (43) 5,932 Total $ 7,563 $ 21 $ (44) $ 7,540 September 30, 2023 Amortized Gross Unrealized Fair Gains Losses (in millions) U.S. government-sponsored debt securities $ 1,109 $ 1 $ (2) $ 1,108 U.S. Treasury securities 4,697 — (80) 4,617 Total $ 5,806 $ 1 $ (82) $ 5,725 Debt securities with unrealized losses for less than 12 months and 12 months or greater were as follows: December 31, 2023 Less Than 12 Months 12 Months or Greater Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (in millions) U.S. government-sponsored debt securities $ 424 $ (1) $ — $ — U.S. Treasury securities 646 (2) 2,056 (41) Total $ 1,070 $ (3) $ 2,056 $ (41) September 30, 2023 Less Than 12 Months 12 Months or Greater Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (in millions) U.S. government-sponsored debt securities $ 412 $ (2) $ 50 $ — U.S. Treasury securities 1,360 (12) 2,128 (68) Total $ 1,772 $ (14) $ 2,178 $ (68) The unrealized losses were primarily attributable to changes in interest rates. The stated maturities of debt securities were as follows: December 31, (in millions) Due within one year $ 4,731 Due after one year through five years 2,809 Total $ 7,540 Equity Securities The Company’s non-marketable equity securities include investments in privately held companies without readily determinable fair values. These investments are measured at fair value on a non-recurring basis and are classified as Level 3 due to the absence of quoted market prices, the inherent lack of liquidity and the fact that significant inputs used to measure fair value are unobservable and require management’s judgment. The following table summarizes the total carrying value of the Company’s non-marketable equity securities that were accounted for using the fair value measurement alternative and held as of December 31, 2023, including the cumulative unrealized gains and losses: December 31, (in millions) Initial cost basis $ 710 Adjustments: Upward adjustments 909 Downward adjustments (including impairment) (430) Carrying amount $ 1,189 Unrealized gains and losses included in the carrying value of the Company’s non-marketable equity securities accounted for using the fair value measurement alternative and still held as of December 31, 2023 and 2022, respectively, were as follows: Three Months Ended 2023 2022 (in millions) Upward adjustments $ 9 $ 17 Downward adjustments (including impairment) $ — $ — For the three months ended December 31, 2023 and 2022, the Company recognized net unrealized gains of $36 million and net unrealized losses of $102 million, respectively, on marketable and non-marketable equity securities still held as of quarter end. Other Fair Value Disclosures Debt. Debt instruments are measured at amortized cost on the Company’s consolidated balance sheets. The fair value of the debt instruments, as provided by third-party pricing vendors, is based on quoted prices in active markets for similar, not identical, assets. If measured at fair value in the financial statements, these instruments would be classified as Level 2 in the fair value hierarchy. As of December 31, 2023, the carrying value and estimated fair value of debt was $20.7 billion and $19.0 billion, respectively. As of September 30, 2023, the carrying value and estimated fair value of debt was $20.5 billion and $17.7 billion, respectively. Other financial instruments not measured at fair value. As of December 31, 2023, the carrying values of settlement receivable and payable and customer collateral are an approximate fair value due to their generally short maturities. If measured at fair value in the financial statements, these financial instruments would be classified as Level 2 in the fair value hierarchy. Non-financial assets.

Settlement Guarantee Management [Abstract]
Settlement Guarantee Management	Note 8—Settlement Guarantee Management The Company indemnifies its clients for settlement losses suffered due to failure of any other client to fund its settlement obligations in accordance with the Visa operating rules. This indemnification creates settlement risk for the Company due to the difference in timing between the date of a payment transaction and the date of subsequent settlement. Historically, the Company has experienced minimal losses as a result of its settlement risk guarantee. However, the Company’s future obligations, which could be material under its guarantees, are not determinable as they are dependent upon future events. The Company’s settlement exposure is limited to the amount of unsettled Visa payment transactions at any point in time, which vary significantly day to day. During the three months ended December 31, 2023, the Company’s maximum daily settlement exposure was $133.2 billion and the average daily settlement exposure was $83.0 billion. The Company maintains and regularly reviews global settlement risk policies and procedures to manage settlement exposure, which may require clients to post collateral if certain credit standards are not met. The Company held the following collateral to manage settlement exposure: December 31, September 30, (in millions) Restricted cash $ 3,164 $ 3,005 Pledged securities 504 411 Letters of credit 1,779 1,738 Guarantees 1,054 1,047 Total $ 6,501 $ 6,201

All share repurchase programs authorized prior to October 2022 have been completed. Class B common stock. On January 23, 2024, Visa’s common stockholders approved amendments to the Company’s certificate of incorporation authorizing Visa to implement an exchange offer program that would have the effect of releasing transfer restrictions on portions of the Company’s class B common stock. The certificate of incorporation amendments automatically redenominate all shares of class B common stock as class B-1 common stock with no changes to the par value, conversion features, rights and privileges of the class B common stock. The amendments also authorized new classes of class B common stock that will only be issuable in connection with an exchange offer where a preceding class of B common stock was tendered in exchange and retired. The new authorization will have no impact to outstanding diluted earnings per class A common stock. Dividends. During the three months ended December 31, 2023 and 2022, the Company declared and paid dividends of $1.1 billion and $945 million, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Note 12—Income Taxes For the three months ended December 31, 2023 and 2022, the effective income tax rates were 19% and 16%, respectively. The difference in the effective tax rates is primarily due to a $142 million tax benefit recognized during the three months ended December 31, 2022 due to the reassessment of an uncertain tax position as a result of new information obtained during an ongoing tax examination. During the three months ended December 31, 2023, the Company’s gross unrecognized tax benefits increased by $113 million. The Company’s net unrecognized tax benefits that, if recognized, would favorably impact the effective tax rate, increased by $29 million. The change in unrecognized tax benefits is related to various tax positions across several jurisdictions. In January 2024, a resolution was reached regarding India tax assessments for years falling within the period from 2010 to 2019. As a result, the Company filed to withdraw appeals to the appellate authorities for these years. Effective through September 30, 2028, the Company’s operating hub in the Asia Pacific region is subject to a tax incentive in Singapore which is conditional upon meeting certain requirements. The Company’s tax filings are subject to examination by U.S. federal, state and foreign taxing authorities. The timing and outcome of the final resolutions of the various ongoing income tax examinations and refund claims are uncertain. However, it is reasonably possible that the Company’s net unrecognized tax benefits could decrease by approximately $400 million in the next 12 months.

Commitments and Contingencies Disclosure [Abstract]
Legal Matters	Note 13—Legal Matters The Company is party to various legal and regulatory proceedings. Some of these proceedings involve complex claims that are subject to substantial uncertainties and unascertainable damages. For those proceedings where a loss is determined to be only reasonably possible or probable but not estimable, the Company has disclosed the nature of the claim. Additionally, unless otherwise disclosed below with respect to these proceedings, the Company cannot provide an estimate of the possible loss or range of loss. Although the Company believes that it has strong defenses for the litigation and regulatory proceedings described below, it could, in the future, incur judgments or fines or enter into settlements of claims that could have a material adverse effect on the Company’s financial position, results of operations or cash flows. From time to time, the Company may engage in settlement discussions or mediations with respect to one or more of its outstanding litigation matters, either on its own behalf or collectively with other parties. The litigation accrual is an estimate and is based on management’s understanding of its litigation profile, the specifics of each case, advice of counsel to the extent appropriate and management’s best estimate of incurred loss as of the balance sheet date. The following table summarizes the activity related to accrued litigation: Three Months Ended 2023 2022 (in millions) Balance as of beginning of period $ 1,751 $ 1,456 Provision for uncovered legal matters 10 — Provision for covered legal matters 22 347 Payments for legal matters (312) (101) Balance as of end of period $ 1,471 $ 1,702 Accrual Summary—U.S. Covered Litigation Visa Inc., Visa U.S.A. and Visa International are parties to certain legal proceedings that are covered by the U.S. retrospective responsibility plan, which the Company refers to as the U.S. covered litigation. An accrual for the U.S. covered litigation and a charge to the litigation provision are recorded when a loss is deemed to be probable and reasonably estimable. In making this determination, the Company evaluates available information, including but not limited to actions taken by the Company’s litigation committee. The total accrual related to the U.S. covered litigation could be either higher or lower than the escrow account balance. See further discussion below under U.S. Covered Litigation and Note 5—U.S. and Europe Retrospective Responsibility Plans. The following table summarizes the accrual activity related to U.S. covered litigation: Three Months Ended 2023 2022 (in millions) Balance as of beginning of period $ 1,621 $ 1,441 Provision for interchange multidistrict litigation — 341 Payments for U.S. covered litigation (160) (101) Balance as of end of period $ 1,461 $ 1,681 Accrual Summary—VE Territory Covered Litigation Visa Inc., Visa International and Visa Europe are parties to certain legal proceedings that are covered by the Europe retrospective responsibility plan. Unlike the U.S. retrospective responsibility plan, the Europe retrospective responsibility plan does not have an escrow account that is used to fund settlements or judgments. The Company is entitled to recover VE territory covered losses through periodic adjustments to the conversion rates applicable to the series B and C preferred stock. An accrual for the VE territory covered losses and a reduction to stockholders’ equity will be recorded when the loss is deemed to be probable and reasonably estimable. See further discussion below under VE Territory Covered Litigation and Note 5—U.S. and Europe Retrospective Responsibility Plans . The following table summarizes the accrual activity related to VE territory covered litigation: Three Months Ended 2023 2022 (in millions) Balance as of beginning of period $ 110 $ 11 Provision for VE territory covered litigation 22 6 Payments for VE territory covered litigation (126) — Balance as of end of period $ 6 $ 17 U.S. Covered Litigation Interchange Multidistrict Litigation (MDL) - Class Actions On December 4, 2023, plaintiffs in the two actions led, respectively, by Hayley Lanning and Camp Grounds Coffee, served a motion for partial summary judgment.

Interchange Multidistrict Litigation (MDL) - Individual Merchant Actions Visa has reached settlements with a number of merchants representing approximately 73% of the Visa-branded payment card sales volume of merchants who opted out of the Amended Settlement Agreement with the Damages Class plaintiffs. On November 1, 2023, defendants served a motion to enforce the Amended Settlement Agreement, or in the alternative for summary judgment, regarding claims in the actions brought by certain plaintiffs in their capacity as payment facilitators. On December 4, 2023, plaintiffs in certain of the individual merchant actions served a motion for partial summary judgment or a joinder in partial summary judgment motions. On January 8, 2024, defendants’ motions for summary judgment under Ohio v. American Express were granted in part and denied in part. VE Territory Covered Litigation Europe Merchant Litigation Since July 2013, proceedings have been commenced by more than 1,150 Merchants (the capitalized term “Merchant” when used in this section, means a Merchant together with subsidiary/affiliate companies that are party to the same claim) against Visa Europe, Visa Inc. and other Visa subsidiaries in the UK and other countries primarily relating to interchange rates in Europe and in some cases relating to fees charged by Visa and certain Visa rules. As of the filing date, Visa has settled the claims asserted by over 475 Merchants, and there are approximately 600 Merchants with outstanding claims. In addition, over 30 additional Merchants have threatened to commence similar proceedings. Standstill agreements have been entered into with respect to some of those threatened Merchant claims, several of which have been settled. Other Litigation MiCamp Solutions On December 8, 2023, a complaint was filed in the U.S. District Court for the Northern District of California by MiCamp Solutions, LLC against Visa on behalf of a purported class of Independent Sales Organizations (ISOs) and their merchant customers and a purported subclass of ISOs. The complaint alleges violations of federal and state antitrust laws, state data privacy laws, and the constitution, based on, among other things, Visa’s interchange fees and its assessment of fees for non-compliance with its surcharge rules. The complaint seeks to recover damages and to enjoin the enforcement of Visa’s default interchange and surcharge rules, among other things. Mirage Wine + Spirit’s Inc. On December 14, 2023, a putative class action was filed in the U.S. District Court for the Southern District of Illinois by Mirage Wine + Spirit’s Inc. against Apple Inc., Visa Inc. and Mastercard Incorporated on behalf of certain merchants in the United States that accepted Apple Pay as a method of payment at the physical point-of-sale from December 14, 2019. Plaintiff alleges a conspiracy under which Apple agreed not to enter a purported market for point-of-sale payment card networks services and seeks damages, injunctive relief and attorneys’ fees based on alleged violations of section 1 of the Sherman Act. On January 5, 2024, Visa requested transfer of the action to the U.S. District Court for the Eastern District of New York for coordinated or consolidated pretrial proceedings with the Interchange Multidistrict Litigation.

Accounting Policies [Abstract]
Consolidation and basis of presentation	Consolidation and basis of presentation. The accompanying unaudited consolidated financial statements include the accounts of Visa and its consolidated entities and are presented in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The Company consolidates its majority-owned and controlled entities, including variable interest entities (VIEs) for which the Company is the primary beneficiary. The Company’s investments in VIEs have not been material to its unaudited consolidated financial statements as of and for the periods presented. Intercompany balances and transactions have been eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with U.S. Securities and Exchange Commission (SEC) requirements for Quarterly Reports on Form 10-Q and, consequently, do not include all of the annual disclosures required by U.S. GAAP. Reference should be made to Visa’s Annual Report on Form 10-K for the year ended September 30, 2023 for additional disclosures, including a summary of the Company’s significant accounting policies. In the opinion of management, the accompanying unaudited consolidated financial statements include all normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented. The results of operations for interim periods are not necessarily indicative of results for the full year.
Use of estimates	Use of estimates. The preparation of the accompanying unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and reported amounts of revenues and expenses during the reporting period. These estimates may change as new events occur and additional information is obtained, and will be recognized in the period in which such changes occur. Future actual results could differ materially from these estimates.
