Income Taxes

 

The Company files income tax returns in the United States Federal jurisdiction, in a limited number of foreign jurisdictions, and in many state jurisdictions. With few exceptions, the Company is no longer subject to United States Federal, state, or foreign income tax examinations for years before 2017.

The Company’s estimated effective income tax rates for the three and six months ended June 30, 2022 were primarily impacted by non-deductible permanent differences. The Company’s estimated effective income tax rate for the three months ended June 30, 2021 was primarily impacted by non-deductible permanent differences, while the estimated effective income tax rate for the six months ended June 30, 2021 was primarily impacted by the tax windfalls recognized upon the vesting of equity awards in the first three months of 2021.
