Summary of Significant Accounting Policies	Jun. 30, 2023
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, 2022 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. Recently Adopted Accounting Pronouncement. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Subsequently, the FASB also issued amendments to this standard. The amendments in the ASU are effective upon issuance through December 31, 2024. During the prior quarter, the Company adopted certain optional expedients provided in this ASU in relation to contract modifications and hedge accounting. The adoption did not have a material impact on the consolidated financial statements.

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 referred to as the “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: Nine Months Ended 2023 2022 (in millions) Balance at beginning of period $ 1,449 $ 894 Deposits into the U.S. litigation escrow account 850 850 Payments to opt-out merchants (1) , net of interest earned on escrow funds (672) (261) Balance at end of period $ 1,627 $ 1,483 (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 a contra-equity account referred to as “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” as contra-equity 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: Preferred Stock Right to Recover for Covered Losses Series B Series C (in millions) Balance as of September 30, 2022 $ 460 $ 812 $ (35) VE territory covered losses incurred (1) — — (21) Recovery through conversion rate adjustment (2) (19) (11) 31 Balance as of June 30, 2023 $ 441 $ 801 $ (25) Preferred Stock Right to Recover for Covered Losses Series B Series C (in millions) Balance as of September 30, 2021 $ 1,071 $ 1,523 $ (133) VE territory covered losses incurred (1) — — (31) Recovery through conversion rate adjustment (135) (6) 141 Balance as of June 30, 2022 $ 936 $ 1,517 $ (23) (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 in stockholders’ equity within the Company’s consolidated balance sheets: June 30, 2023 September 30, 2022 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 $ 1,730 $ 441 $ 1,309 $ 460 Series C preferred stock 2,721 801 2,044 812 Total 4,451 1,242 3,353 1,272 Less: right to recover for covered losses (25) (25) (35) (35) Total recovery for covered losses available $ 4,426 $ 1,217 $ 3,318 $ 1,237 (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 June 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) $237.48, Visa’s class A common stock closing stock price. (3) As of September 30, 2022, 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) 2.971 and 3.645, the class A common stock conversion rate applicable to the series B and C preferred stock outstanding, respectively; and (c) $177.65, 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: June 30, 2023 Amortized Gross Unrealized Fair Gains Losses (in millions) U.S. government-sponsored debt securities $ 1,155 $ — $ (2) $ 1,153 U.S. Treasury securities 4,062 — (99) 3,963 Total $ 5,217 $ — $ (101) $ 5,116 September 30, 2022 Amortized Gross Unrealized Fair Gains Losses (in millions) U.S. government-sponsored debt securities $ 458 $ — $ (1) $ 457 U.S. Treasury securities 4,937 — (133) 4,804 Total $ 5,395 $ — $ (134) $ 5,261 Debt securities with unrealized losses for less than 12 months and 12 months or greater were as follows: June 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 $ 584 $ (2) $ — $ — U.S. Treasury securities 1,524 (17) 2,165 (82) Total $ 2,108 $ (19) $ 2,165 $ (82) September 30, 2022 Less Than 12 Months Fair Value Gross Unrealized Losses (in millions) U.S. government-sponsored debt securities $ 408 $ (1) U.S. Treasury securities 3,507 (133) Total $ 3,915 $ (134) The unrealized losses were primarily attributable to changes in interest rates. The stated maturities of debt securities were as follows: June 30, (in millions) Due within one year $ 2,994 Due after 1 year through 5 years 2,122 Total $ 5,116 Equity Securities The Company’s non-marketable equity securities are investments in privately held companies without readily determinable market 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 held as of June 30, 2023 including cumulative unrealized gains and losses: June 30, (in millions) Initial cost basis $ 764 Adjustments: Upward adjustments 899 Downward adjustments (including impairment) (431) Carrying amount, end of period $ 1,232 Unrealized gains and losses included in the carrying value of the Company’s non-marketable equity securities still held as of June 30, 2023 and 2022 were as follows: Three Months Ended Nine Months Ended 2023 2022 2023 2022 (in millions) Upward adjustments $ 75 $ 5 $ 94 $ 231 Downward adjustments (including impairment) $ — $ (284) $ (86) $ (337) For the three months ended June 30, 2023 and 2022, the Company recognized net unrealized gains of $96 million and net unrealized losses of $278 million, respectively, on marketable and non-marketable equity securities still held as of quarter end. For the nine months ended June 30, 2023 and 2022, the Company recognized net unrealized losses of $85 million and $262 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 June 30, 2023, the carrying value and estimated fair value of debt was $20.6 billion and $18.6 billion, respectively. As of September 30, 2022, the carrying value and estimated fair value of debt was $22.5 billion and $19.9 billion, respectively. Other financial instruments not measured at fair value. As of June 30, 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.

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 nine months ended June 30, 2023, the Company’s maximum daily settlement exposure was $125.6 billion and the average daily settlement exposure was $76.3 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: June 30, September 30, (in millions) Restricted cash and restricted cash equivalents $ 2,907 $ 2,342 Pledged securities at market value 408 213 Letters of credit 1,717 1,582 Guarantees 1,094 950 Total $ 6,126 $ 5,087

Income Taxes	Note 12—Income Taxes For the three and nine months ended June 30, 2023, the effective income tax rates were 19% and 18%, respectively, and for the three and nine months ended June 30, 2022, the effective income tax rates were 11% and 17%, respectively. The difference in the effective tax rates is primarily due to the following: • During the nine months ended June 30, 2023, a $142 million tax benefit related to prior years due to the reassessment of an uncertain tax position as a result of new information obtained during an ongoing tax examination; and • During the three months ended June 30, 2022, a $176 million tax benefit related to prior years due to a decrease in the state apportionment ratio as a result of a tax position taken related to a ruling. During the three and nine months ended June 30, 2023, the Company’s gross unrecognized tax benefits increased by $615 million and $593 million, respectively. The Company’s net unrecognized tax benefits that, if recognized, would favorably impact the effective tax rate, increased by $315 million and $192 million, respectively. The change in unrecognized tax benefits is related to various tax positions across several jurisdictions, including refund claims filed during the quarter. Additionally, the nine month period reflects the change in unrecognized tax benefits related to the reassessment mentioned above. 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 are highly uncertain. It is not reasonably possible to estimate the increase or decrease in unrecognized tax benefits within the next twelve 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: Nine Months Ended 2023 2022 (in millions) Balance at beginning of period $ 1,456 $ 983 Provision for uncovered legal matters 1 2 Provision for covered legal matters 808 878 Payments for legal matters (720) (377) Balance at end of period $ 1,545 $ 1,486 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: Nine Months Ended 2023 2022 (in millions) Balance at beginning of period $ 1,441 $ 881 Provision for interchange multidistrict litigation 797 861 Payments for U.S. covered litigation (699) (262) Balance at end of period $ 1,539 $ 1,480 During the three and nine months ended June 30, 2023, the Company recorded additional accruals of $456 million and $797 million, respectively, and deposited $500 million and $850 million, respectively, into the U.S. litigation escrow account to address claims associated with the interchange multidistrict litigation. The U.S. covered litigation accrual balance is consistent with the Company’s best estimate of its share of a probable and reasonably estimable loss with respect to the U.S. covered litigation. While this estimate is consistent with the Company’s view of the current status of the litigation, the probable and reasonably estimable loss or range of such loss could materially vary based on developments in the litigation. The Company will continue to consider and reevaluate this estimate in light of the substantial uncertainties with respect to the litigation. The Company is unable to estimate a potential loss or range of loss, if any, at trial if negotiated resolutions cannot be reached. 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: Nine Months Ended 2023 2022 (in millions) Balance at beginning of period $ 11 $ 102 Provision for VE territory covered litigation 11 17 Payments for VE territory covered litigation (19) (114) Balance at end of period $ 3 $ 5 U.S. Covered Litigation Interchange Multidistrict Litigation (MDL) - Putative Class Actions On March 15, 2023, the U.S. Court of Appeals for the Second Circuit affirmed the final approval of the Amended Settlement Agreement by the district court. Interchange Multidistrict Litigation (MDL) - Individual Merchant Actions Visa has reached settlements with a number of merchants representing approximately 70% of the Visa-branded payment card sales volume of merchants who opted out of the Amended Settlement Agreement with the Damages Class plaintiffs. Additional summary judgment motions were filed by plaintiffs and defendants in an individual merchant action. On July 14, 2023, Block, Inc. filed a lawsuit against Visa Inc., Visa U.S.A., Visa International, Mastercard Incorporated, and Mastercard International Incorporated in the U.S. District Court for the Eastern District of New York, generally pursuing claims on allegations similar to those raised in MDL 1720. Square, a business unit of Block, Inc., previously submitted a request to opt out of the Amended Settlement Agreement. The parties have requested reassignment of the case to the judge presiding over MDL 1720 for inclusion in MDL 1720. Consumer Interchange Litigation On December 30, 2022, a putative class action was filed in California state court against Visa, Mastercard, and certain financial institutions on behalf of all Visa and Mastercard cardholders in California who made a purchase using a Visa-branded or Mastercard-branded payment card in California from January 1, 2004. Plaintiffs primarily allege a conspiracy to fix interchange fees and seek injunctive relief, attorneys’ fees and damages as direct and indirect purchasers based on alleged violations of California law. On January 11, 2023, plaintiffs filed an amended complaint asserting the same claims as asserted in the prior complaint. On January 30, 2023, Visa removed the action to federal court. On February 10, 2023, the Judicial Panel on Multidistrict Litigation issued an order transferring the case to MDL 1720. On June 15, 2023, plaintiffs’ motion to remand the case to California state court was denied, and plaintiffs have appealed. VE Territory Covered Litigation Europe Merchant Litigation Since July 2013, proceedings have been commenced by more than 1,100 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 175 Merchants, and there are approximately 900 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. On June 8, 2023, the UK Competition Appeal Tribunal denied class certification in the two class action claims. Other Litigation Visa’s motion challenging jurisdiction in the class action regarding interchange on cross-border transactions and the Honor All Cards rule in Israel was denied. Other Litigation U.S. ATM Access Fee Litigation On July 25, 2023, the U.S. Court of Appeals for the District of Columbia Circuit affirmed the district court’s class certification decisions. European Commission Staged Digital Wallets Investigation On February 16, 2023, the European Commission (EC) notified Visa that the matter has been closed. German ATM Litigation On July 6, 2023, one of the challenges to the jurisdiction of the German courts was denied. EMV Chip Liability Shift On November 30, 2022, Visa, jointly with other defendants, served a motion for summary judgment regarding the claims in the amended complaint and a motion to decertify the class. U.S. Department of Justice Civil Investigative Demand (2021) On January 4, 2023 and May 2, 2023, the Antitrust Division of the U.S. Department of Justice (Division) issued further Civil Investigative Demands seeking additional documents and information focusing on U.S. debit and competition with other payment methods and networks. Visa is cooperating with the Division in connection with the investigation. Foreign Currency Exchange Rate Litigation On December 21, 2022, plaintiffs filed a third amended complaint asserting the same claims as asserted in the prior complaints. On February 3, 2023, Visa filed a motion to dismiss the third amended complaint. European Commission Client Incentive Agreements Investigation On December 2, 2022, the EC informed Visa that it had opened a preliminary investigation into Visa’s incentive agreements with clients. Visa is cooperating with the EC in connection with the investigation.

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, 2022 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.
Recently Adopted Accounting Pronouncement	Recently Adopted Accounting Pronouncement. In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. Subsequently, the FASB also issued amendments to this standard. The amendments in the ASU are effective upon issuance through December 31, 2024. During the prior quarter, the Company adopted certain optional expedients provided in this ASU in relation to contract modifications and hedge accounting. The adoption did not have a material impact on the consolidated financial statements.
