Income Taxes Income Taxes
Income tax was an expense of $1.28 billion and $2.24 billion for the third quarter and first nine months of fiscal year 2024, respectively, and a benefit of $67 million and $61 million for the third quarter and first nine months of fiscal year 2023, respectively. Income tax as a percentage of income before income tax was an expense of 12.2% and 11.3% for the third quarter and first nine months of fiscal year 2024, respectively, and a benefit of 10.9% and 2.1% for the third quarter and first nine months of fiscal year 2023, respectively.

During the third quarter of fiscal year 2024, the Internal Revenue Service, or IRS, audit of our federal income tax returns for fiscal years 2018 and 2019 was resolved. We recognized a non-cash net benefit of $145 million, related to this IRS audit resolution, for effectively settled positions. This benefit consists of a reduction in unrecognized tax benefits of $236 million and related accrued interest of $17 million, net of federal benefit partially offset by additional cash tax payments and reductions in tax attribute carryforwards of $108 million.

The effective tax rate increased due to a decreased impact of tax benefits from the foreign-derived intangible income deduction, stock-based compensation, and the U.S. federal research tax credit, relative to the increase in income before income tax. The increase in the effective tax rate was partially offset by a benefit due to the IRS audit resolution.

Our effective tax rates for the first nine months of fiscal years 2024 and 2023 were lower than the U.S. federal statutory rate of 21% due to tax benefits from the foreign-derived intangible income deduction, stock-based compensation and the U.S. federal research tax credit. Our effective tax rate for the first nine months of fiscal year 2024 was additionally benefited by the IRS audit resolution.
Other than the IRS audit resolution, for the first nine months of fiscal year 2024, there were no material changes to our tax years that remain subject to examination by major tax jurisdictions. Additionally, there have been no other material changes to our unrecognized tax benefits and any related interest or penalties since the fiscal year ended January 29, 2023. While we believe that we have adequately provided for all uncertain tax positions, or tax positions where we believe it is not more-likely-than-not that the position will be sustained upon review, amounts asserted by tax authorities could be greater or less than our accrued position. Accordingly, our provisions on federal, state and foreign tax related matters to be recorded in the future may change as revised estimates are made or the underlying matters are settled or otherwise resolved with the respective tax authorities. As of October 29, 2023, we do not believe that our estimates, as otherwise provided for, on such tax positions will significantly increase or decrease within the next 12 months.
