For the three and six months ended July 31, 2026, discrete tax items impacting the effective tax rate were primarily due to tax benefit from stock-based compensation expense. For the three and six months ended July 31, 2025, discrete tax items impacting the effective tax rate were primarily due to tax benefit from stock-based compensation expense and changes to net state deferred tax liabilities due to state apportionment changes.
As of July 31, 2026 and January 31, 2026, the Company’s total gross unrecognized tax benefit was $29.6 million and $27.4 million, respectively. If recognized, $26.1 million of the total gross unrecognized tax benefit would affect the Company's effective tax rate as of July 31, 2026.
The Company files income tax returns with U.S. federal and state taxing jurisdictions and is currently under examination by the state of California. This tax examination may lead to ordinary course adjustments or proposed adjustments to the Company's taxes, net operating losses, and/or tax credit carryforwards. As a result of the Company's net operating loss carryforwards and tax credit carryforwards, the Company remains subject to examination by one or more jurisdictions for tax years after 2006.
