Income Taxes
Note 5 Income Taxes
The effective tax rate on Income before income taxes for the three and nine months ended September 30, 2023 was 86.0% and 77.4%, respectively. These effective tax rates were higher than normal due primarily to the nominally low amount of Income before income taxes in the current year, which increased the effective tax rate impact of recurring tax adjustments including nondeductible interest and compensation expenses, as well as discrete increases in state valuation allowances that reduce the net value of deferred tax assets.
The effective tax rate on Income (loss) before income taxes for the three and nine months ended September 30, 2022 was 24.4% and 37.7%, respectively. These effective tax rates reflect a combined rate of federal and state taxes, adjusted primarily for impacts of nondeductible compensation and interest expense. The effective tax rates also varied during interim periods due to fluctuations in Income (loss) before income taxes.
