The following table provides details of income taxes:
Three Months Ended December 31, Six Months Ended December 31,
(Dollar amounts in thousands) 2023 2022 2023 2022
Income before income taxes $ 691,270 $ 1,142,973 $ 1,542,981 $ 2,213,001
Provision for income taxes $ 108,736 $ 164,178 $ 219,072 $ 208,141
Effective tax rate 15.7  % 14.4  % 14.2  % 9.4  %
Our effective tax rate is lower than the U.S. federal statutory rate during the six months ended December 31, 2023 primarily due to the proportion of earnings generated in jurisdictions with tax rates lower than the U.S. statutory rate and the proportion of U.S. earnings eligible for the Foreign Derived Intangible Income deduction.
In the normal course of business, we are subject to examination by tax authorities throughout the world. We are subject to U.S. federal income tax examinations for all years beginning from the fiscal year ended June 30, 2018 and are under United States income tax examination for the fiscal years ended June 30, 2018, June 30, 2019 and June 30, 2020. We are subject to state income tax examinations for all years beginning from the fiscal year ended June 30, 2019. We are also subject to examinations in other major foreign jurisdictions, including Singapore and Israel, for all years beginning from the calendar year ended December 31, 2019.
It is possible that certain examinations may be concluded in the next 12 months. The timing and resolution of income tax examinations are uncertain. Given the uncertainty around the timing of the resolution of these ongoing examinations, we are unable to estimate the full range of possible adjustments to our unrecognized tax benefits within the next 12 months.
Legislative Developments
President Biden signed into law the CHIPS and Science Act of 2022 (“CHIPS Act,” where “CHIPS” stands for Creating Helpful Incentives to Produce Semiconductors) on August 9, 2022. The CHIPS Act provides for various incentives and tax credits among other items, including the Advanced Manufacturing Investment Credit (“AMIC”) which equals 25% of qualified investments in an advanced manufacturing facility that is placed in service after December 31, 2022. There was no material impact to our financial statements from the AMIC provision during the six months ended December 31, 2023.
President Biden also signed into law the IRA on August 16, 2022. The IRA has several new provisions including a 15% corporate alternative minimum tax (“CAMT”) for certain large corporations that have at least an average of $1.0 billion of adjusted financial statement income over a consecutive three-tax-year period. The CAMT was effective for us beginning in the quarter ended September 30, 2023 and we are not expecting to have any tax impact from the CAMT for the fiscal year ending June 30, 2024.
The IRA also introduced a 1% excise tax imposed on certain stock repurchases by publicly traded companies made after December 31, 2022. We began recording the excise tax as part of the cost basis of treasury stock repurchased after December 31, 2022.
Other than the AMIC, the CAMT and the excise tax imposed on certain stock repurchases as mentioned above, we are currently evaluating the applicability and impact of the other provisions in the IRA and the CHIPS Act on our Condensed Consolidated Financial Statements including our future cash flows.
