9. Income Taxes

The provision for income tax was an expense of $26.9 million and $77.0 million in the three and nine months ended January 31, 2022, respectively, with an effective tax rate of 24.0% and 24.4%, respectively, compared to an expense of $21.2 million and $25.4 million in the three and nine months ended January 31, 2021, respectively, with an effective tax rate of 29.1% and 34.2%, respectively. In addition to the impact of U.S. state income taxes and the jurisdictional mix of earnings, which generally create variability in our effective tax rate over time, the effective tax rate in the three and nine months ended January 31, 2021 was affected by the tax expense recorded for withholding taxes on inter-company dividends that are not eligible for credit and a shortfall recorded in connection with stock-based awards that vested in the three months ended July 31, 2020. The shortfall is the amount by which the Company’s tax deduction for these awards, based on the fair market value of the awards on the date of vesting, is less than the expense recorded in the Company’s financial statements over the awards’ vesting period.
