Income tax expense$74,204 $76,591 $118,067 $110,119 
Effective income tax rate21.7 %24.0 %22.5 %23.5 %
The tax provisions during the three and six months ended September 30, 2025, and 2024, were computed using the estimated effective income tax rate applicable to each of the domestic and foreign taxable jurisdictions for the current fiscal year, and prior fiscal year, respectively, and were adjusted for discrete items that occurred within the periods presented above. During the three and six months ended September 30, 2025, the net change in the effective income tax rate, compared to the prior period, was primarily due to non-recurring changes in valuation allowances on tax attributes, net discrete tax benefits for audit settlements and adjustments to income taxes payable, and changes in jurisdictional mix of worldwide income before income taxes, partially offset by reduced tax benefits for stock-based compensation. In addition, the net change in the effective tax rate during the six months ended September 30, 2025 included an income tax expense for reserve adjustments.
Recent Tax Law Changes. On July 4, 2025, H.R. 1, also known as the One Big Beautiful Bill Act (OBBBA), was signed into law. The OBBBA includes, among other provisions, changes to US corporate income tax law, including restoration of accelerated depreciation on capital expenditures, deductible research and development expenses, and modifications to the international tax framework. The Company continues to evaluate the impact of the law on its condensed consolidated financial statements as more information becomes available, although it expects to achieve cash tax savings as a result of the full expensing of US research and development expenses in the current fiscal year.
