14.  Income Taxes

The Company’s effective tax rate was 26.0% for the quarter ended March 31, 2021 compared to 24.8% for the quarter ended March 31, 2020. The effective income tax rate for both periods was different than the Company’s statutory rate, primarily due to state taxes and non-deductible expenses.

The total amount of gross unrecognized tax benefits that would reduce the Company’s effective tax rate was $0.8 million at March 31, 2021 and December 31, 2020.

The Company and its subsidiaries file U.S. Federal, state and local, and non-U.S. income tax returns. As of March 31, 2021, the Company is no longer subject to U.S. Federal examination by tax authorities for tax years before 2015. The Company’s 2017 U.S. Federal tax return is currently under audit by the Internal Revenue Service (“IRS”). The IRS began the examination in 2019 and there have been no changes resulting from this audit as of March 31, 2021. The Company is subject to state and local examinations for tax years of 2015 through 2019. In addition, the Company is subject to non-U.S. income tax examinations for tax years of 2015 through 2019.
