12. Income Taxes

For the three and six months ended June 30, 2022, the effective tax rate for continuing operations was 26.0% and 24.4%, respectively, which differed from the statutory federal rate of 21% primarily due to state income taxes and nondeductible executive compensation. The effective tax rate increased during the three and six months ended June 30, 2022 compared to the same period in 2021, primarily due to the impact of quarterly discrete tax items relative to the income before taxes for the respective periods, including the excess tax benefit from stock-based compensation and prior period tax credits.
For the three and six months ended June 30, 2021, the effective tax rate for continuing operations was 24.8% and 23.7% which differed from the statutory federal rate of 21% primarily due to state income taxes, as well as unfavorable permanent differences including executive compensation.
