Summary of Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1—Summary of Significant Accounting Policies Organization. Visa Inc. (“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 and its wholly-owned consolidated subsidiaries operate one of the world’s largest electronic payments network — VisaNet — which provides transaction processing services (primarily authorization, clearing and settlement). The Company offers products and solutions that facilitate secure, reliable and efficient money movement for all 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. All significant intercompany accounts and transactions are eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with the 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 the Visa Annual Report on Form 10-K for the year ended September 30, 2021 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. As the effects of the evolving coronavirus (“COVID-19”) pandemic continue, much remains uncertain. There have been no comparable recent events and as a result the ultimate impact of COVID-19 and the extent to which COVID-19 and new variants continue to impact the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict. Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in the existing guidance and making other minor improvements. The Company adopted this guidance effective October 1, 2021. The adoption did not have a material impact on the consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, which clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for purposes of applying the fair value measurement alternative. The Company adopted this guidance effective October 1, 2021. The adoption did not have a material impact on the consolidated financial statements.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Note 2—Acquisitions Closed Acquisition On December 20, 2021, Visa acquired The Currency Cloud Group Limited (“Currencycloud”), a UK-based global platform that enables banks and fintechs to provide innovative foreign exchange solutions for cross-border payments, for a total purchase consideration of $893 million (which includes the fair value of Visa’s previously held equity interest in Currencycloud). As a result of this transaction closing days before the quarter-end, the initial allocation of the purchase price has not yet been completed. On a provisional basis, the Company allocated $210 million to technology, intangible assets and deferred tax liabilities and $683 million to goodwill. The Company expects to finalize the purchase price allocation once the information required to complete the accounting is available, but no later than one year from the acquisition date. Pending Acquisition On June 24, 2021, Visa entered into a definitive agreement to acquire Tink AB (“Tink”) for €1.8 billion, inclusive of cash and retention incentives. Tink is a European open banking platform that enables financial institutions, fintechs and merchants to build tailored financial management tools, products and services for European consumers and businesses based on their financial data. This acquisition is subject to customary closing conditions, including regulatory reviews and approvals.

Retrospective Responsibility Plan [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: Three Months Ended 2021 2020 (in millions) Balance at beginning of period $ 894 $ 901 Deposits into the litigation escrow account 250 — Payments to opt-out merchants (1) and interest earned on escrow funds — (7) Balance at end of period $ 1,144 $ 894 (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 (the “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 (the “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 “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. During the three months ended December 31, 2021, the Company recovered $29 million of VE territory covered losses through adjustments to the class A common stock conversion rates applicable to the series B and C preferred stock.

Money market funds, marketable equity securities and U.S. Treasury 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 and liabilities. 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. As of December 31, 2021 and September 30, 2021, gross unrealized gains and losses were not material. As of December 31, 2021, $2.3 billion of the Company’s debt securities are due within one year and $2.1 billion is due between one to five years. Assets Measured at Fair Value on a Non-recurring Basis Non-marketable equity securities. The Company’s non-marketable equity securities are investments in privately held companies without readily determinable market values. These investments are classified as Level 3 due to the absence of quoted market prices, the inherent lack of liquidity and the fact that 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 December 31, 2021 including cumulative unrealized gains and losses: December 31, (in millions) Initial cost basis $ 893 Adjustments: Upward adjustments 818 Downward adjustments (including impairment) (13) Carrying amount, end of period $ 1,698 Unrealized gains and losses included in the carrying value of the Company’s non-marketable equity securities still held as of December 31, 2021 and 2020 were as follows: Three Months Ended 2021 2020 (in millions) Upward adjustments $ 224 $ 14 Downward adjustments (including impairment) $ — $ (2) The Company recognized net unrealized gains on marketable and non-marketable equity securities still held as of quarter end of $172 million and $29 million for the three months ended December 31, 2021 and 2020, respectively. Non-financial assets and liabilities. Certain non-financial assets such as goodwill, intangible assets and property, equipment and technology are only recognized at fair value if they are deemed to be impaired. As of December 31, 2021, there were no impairment indicators. Other Fair Value Disclosures Debt. Debt instruments are measured at amortized cost on the Company’s unaudited 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, 2021, the carrying value and estimated fair value of debt was $20.9 billion and $22.5 billion, respectively. As of September 30, 2021, the carrying value and estimated fair value of debt was $21.0 billion and $22.5 billion, respectively. Other financial instruments not measured at fair value. At December 31, 2021, the carrying value of settlement receivable and payable and customer collateral approximates 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 three months ended December 31, 2021, the Company’s maximum daily settlement exposure was $112.7 billion and the average daily settlement exposure was $72.4 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 and restricted cash equivalents $ 2,284 $ 2,260 Pledged securities at market value 273 254 Letters of credit 1,545 1,518 Guarantees 765 758 Total $ 4,867 $ 4,790

(4) The class B to class A common stock conversion rate is presented on a rounded basis. Conversion calculations for dividend payments are based on a conversion rate rounded to the tenth decimal. Reduction in as-converted shares. Under the terms of the U.S. retrospective responsibility plan, when the Company funds the U.S. litigation escrow account, the value of the Company’s class B common stock is subject to dilution through a downward adjustment to the conversion rate of the shares of class B common stock to shares of class A common stock. Under the terms of the Europe retrospective responsibility plan, the Company is entitled to recover VE territory covered losses through periodic adjustments to the class A common stock conversion rates applicable to the series B and C preferred stock. The deposit and recovery have the same economic effect on earnings per share as repurchasing the Company’s class A common stock, because it reduces the class B common stock and the series B and C preferred stock conversion rates and consequently, reduces the as-converted class A common stock share count. See Note 5—U.S. and Europe Retrospective Responsibility Plans . The following table presents the reduction in the number of as-converted class B common stock after deposit into the U.S. litigation escrow account for the three months ended December 31, 2021. There was no comparable adjustment recorded for class B common stock for the three months ended December 31, 2020.

Previously, in January 2021, the Company’s board of directors authorized an $8.0 billion share repurchase program (the “January 2021 Program”). These authorizations have no expiration date. As of December 31, 2021, the Company’s repurchase programs had remaining authorized funds of $12.7 billion. All share repurchase programs authorized prior to the January 2021 Program have been completed. Dividends. On January 25, 2022, the Company’s board of directors declared a quarterly cash dividend of $0.375 per share of class A common stock (determined in the case of class B and C common stock and series A, B and C preferred stock on an as-converted basis), which will be paid on March 1, 2022, to all holders of record as of February 11, 2022. The Company declared and paid dividends of $809 million and $703 million during the three months ended December 31, 2021 and 2020, respectively.

Earnings Per Share

Earnings Per Share	3 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Note 10—Earnings Per Share Basic earnings per share is computed by dividing net income available to each class of shares by the weighted-average number of shares of common stock outstanding and participating securities during the period. Participating securities include the Company’s series A, B and C preferred stock and restricted stock units (“RSUs”) that contain non-forfeitable rights to dividends or dividend equivalents. Net income is allocated to each class of common stock and participating securities based on its proportional ownership on an as-converted basis. The weighted-average number of shares outstanding of each class of common stock reflects changes in ownership over the periods presented. See Note 9—Stockholders’ Equity . Diluted earnings per share is computed by dividing net income available by the weighted-average number of shares of common stock outstanding, participating securities and, if dilutive, potential class A common stock equivalent shares outstanding during the period. Dilutive class A common stock equivalents may consist of: (1) shares of class A common stock issuable upon the conversion of series A, B and C preferred stock and class B and C common stock based on the conversion rates in effect through the period, and (2) incremental shares of class A common stock calculated by applying the treasury stock method to the assumed exercise of employee stock options, the assumed purchase of stock under the Company’s Employee Stock Purchase Plan and the assumed vesting of unearned performance shares. The following table presents earnings per share for the three months ended December 31, 2021: Basic Earnings Per Share Diluted Earnings Per Share Income Allocation (A) (1) Weighted- Earnings per Share = (A)/(B) (2) Income Allocation (A) (1) Weighted- Earnings per Share = (A)/(B) (2) (in millions, except per share data) Class A common stock $ 3,065 1,669 $ 1.84 $ 3,959 2,159 (3) $ 1.83 Class B common stock 732 245 $ 2.98 $ 731 245 $ 2.98 Class C common stock 74 10 $ 7.35 $ 74 10 $ 7.34 Participating securities (4) 88 Not presented Not presented $ 88 Not presented Not presented Net income $ 3,959 The following table presents earnings per share for the three months ended December 31, 2020: Basic Earnings Per Share Diluted Earnings Per Share Income Allocation (A) (1) Weighted- Earnings per Share = (A)/(B) (2) Income Allocation (A) (1) Weighted- Earnings per Share = (A)/(B) (2) (in millions, except per share data) Class A common stock $ 2,410 1,694 $ 1.42 $ 3,126 2,200 (3) $ 1.42 Class B common stock 567 245 $ 2.31 $ 566 245 $ 2.31 Class C common stock 61 11 $ 5.69 $ 61 11 $ 5.68 Participating securities 88 Not presented Not presented $ 89 Not presented Not presented Net income $ 3,126 (1) Net income is allocated based on proportional ownership on an as-converted basis.

The weighted-average number of shares of as-converted class C common stock used in the income allocation was 40 million and 43 million for the three months ended December 31, 2021 and 2020, respectively. The weighted-average number of shares of preferred stock included within participating securities was 7 million and 21 million of as-converted series A preferred stock for the three months ended December 31, 2021 and 2020, respectively, 16 million of as-converted series B preferred stock for the three months ended December 31, 2021 and 2020, and 22 million of as-converted series C preferred stock for the three months ended December 31, 2021 and 2020. (2) Figures in the table may not recalculate exactly due to rounding. Earnings per share is calculated based on unrounded numbers.

Income Tax Disclosure [Abstract]
Income Taxes	Note 12—Income Taxes For the three months ended December 31, 2021 and 2020, the effective income tax rates were 19% and 17%, respectively. The difference in the effective tax rates is primarily due to an $81 million tax benefit recognized during the three months ended December 31, 2020 as a result of the conclusion of audits by taxing authorities. During the three months ended December 31, 2021, the Company’s gross unrecognized tax benefits increased by $78 million, of which $29 million would favorably impact the effective tax rate, if recognized. The change in unrecognized tax benefits is primarily related to various tax positions across several jurisdictions. 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.

Legal Matters [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. Accordingly, except as disclosed, the Company has not established reserves or ranges of possible loss related to these proceedings, as at this time in the proceedings, the matters do not relate to a probable loss and/or the amount or range of losses are not reasonably estimable. 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 2021 2020 (in millions) Balance at beginning of period $ 983 $ 914 Provision for uncovered legal matters 1 1 Provision for covered legal matters 146 10 Payments for legal matters (103) (16) Balance at end of period $ 1,027 $ 909 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 2021 2020 (in millions) Balance at beginning of period $ 881 $ 888 Provision for interchange multidistrict litigation 145 — Payments for U.S. covered litigation — (7) Balance at end of period $ 1,026 $ 881 During the quarter ended December 31, 2021, the Company recorded an additional accrual of $145 million and deposited $250 million into the U.S. litigation escrow account to address claims of certain merchants who opted out of the Amended Settlement Agreement. The U.S. covered litigation accrual balance is consistent with the Company’s estimate of its share of the lower end of a probable and reasonably estimable loss with respect to 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: Three Months Ended 2021 2020 (in millions) Balance at beginning of period $ 102 $ 21 Provision for VE territory covered litigation 1 10 Payments for VE territory covered litigation (102) (9) Balance at end of period $ 1 $ 22 U.S. Covered Litigation Interchange Multidistrict Litigation (MDL) - Individual Merchant Actions Visa has reached settlements with a number of merchants representing approximately 40% of the Visa-branded payment card sales volume of merchants who opted out of the Amended Settlement Agreement with the Damages Class plaintiffs. VE Territory Covered Litigation Europe Merchant Litigation Since July 2013, in excess of 800 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) have commenced proceedings against Visa Europe, Visa Inc. and other Visa subsidiaries in the UK, Belgium and Poland 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 150 Merchants, leaving more than 650 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 November 26, 2021, with respect to certain pending Merchant claims, the UK Competition Appeal Tribunal (CAT) found that UK and certain other domestic and intra-European Economic Area consumer interchange fees before the introduction of the Interchange Fee Regulation (IFR) were a restriction of competition, but that the question of whether those fees are a restriction of competition after the introduction of the IFR would need to be resolved at trial. Whether any interchange fees are exempt from the finding of restriction under applicable law and the assessment of damages, if any, will also need to be considered at trial. Other Litigation German ATM Litigation In December 2021 and January 2022, Visa was served with claims in Germany brought by German savings banks against Visa Europe and Visa Inc. The banks claim that Visa’s ATM rules prohibiting the charging of access fees on domestic cash withdrawals are anti-competitive and they are seeking damages. Foreign Currency Exchange Rate Litigation On December 6, 2021, an amended complaint making similar allegations regarding the setting of foreign exchange rates was filed by several individuals on behalf of a nationwide class, and/or California, Washington, Massachusetts or New Jersey subclasses, of cardholders who made a transaction in a foreign currency. The amended complaint asserts claims for unjust enrichment and restitution as well as violations of the California Unfair Competition Law, the Washington Consumer Protection Act, the Massachusetts Consumer Protection Act, and the New Jersey Consumer Fraud Act. On January 19, 2022, Visa filed a motion to dismiss the amended complaint.

The Company’s investments in VIEs have not been material to its unaudited consolidated financial statements as of and for the periods presented. All significant intercompany accounts and transactions are eliminated in consolidation. The accompanying unaudited consolidated financial statements are presented in accordance with the 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 the Visa Annual Report on Form 10-K for the year ended September 30, 2021 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. As the effects of the evolving coronavirus (“COVID-19”) pandemic continue, much remains uncertain. There have been no comparable recent events and as a result the ultimate impact of COVID-19 and the extent to which COVID-19 and new variants continue to impact the Company’s business, results of operations and financial condition will depend on future developments, which are highly uncertain and difficult to predict.
Recently adopted accounting pronouncements	Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in the existing guidance and making other minor improvements. The Company adopted this guidance effective October 1, 2021. The adoption did not have a material impact on the consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, which clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for purposes of applying the fair value measurement alternative. The Company adopted this guidance effective October 1, 2021. The adoption did not have a material impact on the consolidated financial statements.
