Income Taxes

Our effective income tax rate was 18.5% and 25.2% for the three months ended March 31, 2022 and 2021, respectively. The decrease from the first quarter of 2021 was primarily due to the beneficial impact of a decrease in current quarter accruals of reserves for uncertain tax positions, as well as the increase in the windfall tax benefits associated with stock compensation.

The total amount of unrecognized tax benefits as of March 31, 2022 was $7.0 million, of which $6.4 million would affect our effective tax rate if recognized. Additionally, the balance of unrecognized tax benefits as of March 31, 2022 also included $0.6 million of tax benefits that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes.

We recognize interest and penalties related to unrecognized tax benefits through income tax expense. As of March 31, 2022, we had $1.2 million accrued for the payment of interest.

We are subject to taxation in the U.S. and various state and foreign jurisdictions. Our tax years from 2018 through 2022 are subject to examination by the tax authorities. With few exceptions, we are no longer subject to U.S. federal, state, local and foreign examinations by tax authorities for the years before 2018.
