Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes The following table presents our income tax provision and our income tax rate for the three and six months ended June 30, 2022 and 2021 (in thousands, except percentages):
| For the three months ended June 30, |  | For the six months ended June 30,
| 2022 |  | 2021 |  | 2022 |  | 2021
Income tax provision | $ | 36,323 |  |  | $ | 35,616 |  |  | $ | 62,774 |  |  | $ | 67,220 |
Income tax rate | 26.5 | % |  | 26.8 | % |  | 26.5 | % |  | 27.0 | %
The difference between the U.S. statutory tax rate of 21% and our income tax rate for both the three and six months ended June 30, 2022 and 2021 was primarily a result of state and local income taxes and other permanent book-to-tax differences. The increase in our income tax provision for the three months ended June 30, 2022 was due to an increase in income before income taxes, while the decrease in our income tax provision for the six months ended June 30, 2022 was a result of a reduction in income before income taxes as well as a decrease in our income tax rate during the period. The decrease in our income tax rate for the three and six months ended June 30, 2022 was attributable to: (a) a reduction in certain permanent book-to-tax differences, (b) the favorable impact of certain discrete tax items during the first half of 2022, including an increase in the income tax benefit recognized upon the issuance of common stock under our share-based compensation programs, and (c) a reduction in our state income tax rate due to a change in the allocation of earnings among the jurisdictions in which our income is taxed. As of June 30, 2022 and December 31, 2021, we had no unrecognized income tax benefits. We file a consolidated federal income tax return including all of our U.S. subsidiaries with the Internal Revenue Service. We additionally file income tax returns with various state, local, and foreign tax agencies. Our income tax returns are subject to audit by various taxing authorities and are currently under examination for the years 2017 through 2018.
