NOTE 10 — INCOME TAXES

Effective Tax Rate

Our effective tax rate was 18% and 19% for the three months ended September 30, 2023 and 2022, respectively. The decrease in our effective tax rate for the current quarter compared to the prior year was primarily due to tax benefits from tax law changes in the first quarter of fiscal year 2024, including the impact from the issuance of Notice 2023-55 by the Internal Revenue Service (“IRS”) and U.S. Treasury Department, which delayed the effective date of final foreign tax credit regulations to fiscal year 2024 for Microsoft.

Our effective tax rate was lower than the U.S. federal statutory rate for the three months ended September 30, 2023, primarily due to earnings taxed at lower rates in foreign jurisdictions resulting from producing and distributing our products and services through our foreign regional operations center in Ireland.

Uncertain Tax Positions

As of September 30, 2023 and June 30, 2023, unrecognized tax benefits and other income tax liabilities were $19.8 billion and $18.7 billion, respectively, and are included in long-term income taxes in our consolidated balance sheets.

We remain under audit by the IRS for tax years 2014 to 2017. With respect to the audit for tax years 2004 to 2013, on September 26, 2023, we received Notices of Proposed Adjustment (“NOPAs”) from the IRS. The primary issues in the NOPAs relate to intercompany transfer pricing. In the NOPAs, the IRS is seeking an additional tax payment of $28.9 billion plus penalties and interest. As of September 30, 2023, we believe our allowances for income tax contingencies are adequate. We disagree with the proposed adjustments and will vigorously contest the NOPAs through the IRS’s administrative appeals office and, if necessary, judicial proceedings. We do not expect a final resolution of these issues in the next 12 months. Based on the information currently available, we do not anticipate a significant increase or decrease to our income tax contingencies for these issues within the next 12 months.

We are subject to income tax in many jurisdictions outside the U.S. Our operations in certain jurisdictions remain subject to examination for tax years 1996 to 2023, some of which are currently under audit by local tax authorities. The resolution of each of these audits is not expected to be material to our consolidated financial statements.
