Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesIncome taxes are recorded in our quarterly financial statements based on our estimated annual effective income tax rate, subject to adjustments for discrete events, should they occur. The effective tax rates used in the calculation of income taxes were 23.9% and 23.4% for the three months ended September 30, 2023 and 2022, respectively. The effective tax rates used in the calculation of income taxes were 23.2% and 22.7% for the six months ended September 30, 2023 and 2022, respectively. The increase in the effective tax rate for the three and six months ended September 30, 2023, compared to the three and six months ended September 30, 2022, was due to discrete items primarily pertaining to state tax rate legislative changes and stock-based compensation.
