Income Taxes

Income Taxes

The Company’s tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate adjusted for discrete interim period tax impacts. Each quarter the Company updates its estimated annual effective tax rate and, if the estimate changes, makes a cumulative adjustment. Changes in the geographical mix, permanent differences or the estimated level of annual pre-tax income can affect the effective tax rate. The Company’s effective tax rate for the three months ended June 30, 2024 and 2023 was 26.5% and 22.7%, respectively. The Company’s effective tax rate for the six months ended June 30, 2024 and 2023 was 26.9% and 23.7%, respectively. The Company’s rate increase during the three and six months ended June 30, 2024 over the prior periods is primarily due to the change in the geographical mix of income, an increase in the valuation allowance and an increase in state taxes on foreign earnings not permanently reinvested.

The Company’s effective tax rates for the three and six months ended June 30, 2024 and 2023 differed from the U.S. federal statutory rates of 21% primarily as a result of state income taxes, nondeductible expenses for tax purposes, foreign rate differential, research and development credits and uncertain tax positions.

As of June 30, 2024 and December 31, 2023, the Company had $11.2 million and $9.7 million, respectively, in liabilities for uncertain income tax positions, including interest and penalties. Accrued interest and penalties related to unrecognized tax benefits are recognized in income tax expense on the Company’s Condensed Consolidated Statements of Income.
