Income taxes
We record our interim provision for income taxes based on our estimated annual effective tax rate, as well as certain items discrete to the current period. The effective tax rate for the three months ended April 30, 2025 and 2024 was 19.0% and 20.8%, respectively. The effective tax rate for the six months ended April 30, 2025 and 2024 was 19.0% and 20.9%, respectively. The effective tax rate for the three and six months ended April 30, 2025 is lower than the U.S. tax rate of 21% primarily due to the foreign-derived intangible income deduction.
