Income Taxes

The Company is subject to income taxes in the U.S. and various state and foreign jurisdictions. Tax statutes and regulations within each jurisdiction are subject to interpretation and require the application of significant judgment.  The Company is currently under examination by the Internal Revenue Service for fiscal years 2017 through 2019 and does not expect the resolution of these examinations to have a material impact on its results of operations, financial condition or cash flows. 

The Company’s total liability for unrecognized tax benefits as of September 30, 2021 and June 30, 2021 was $32.9 million and $31.5 million, respectively. The $32.9 million unrecognized tax benefit at September 30, 2021, if recognized, would positively impact the Company’s effective tax rate.

The Company’s effective income tax rate was 24.5 percent for the three months ended September 30, 2021, and 24.8 percent for the three months ended September 30, 2020. The Company’s effective income tax rate was lower in the current period primarily due to an increase in research and development credits and an increase in excess tax benefits related to employee stock-based compensation.
