Income Tax Disclosure [Abstract]  



For interim income tax reporting, the Company estimates its annual effective tax rate and applies it to fiscal year-to-date pretax loss, excluding unusual or infrequently occurring discrete items. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded. The Company reported an income tax benefit of $0.6 million and income tax benefit of $0.7 million for the three months ended June 30, 2023 and 2022, respectively. For the six months ended June, 30 2023 and 2022, the Company reported income tax benefit of $1.2 million and income tax benefit of $1.3 million, respectively.


Each reporting period, we evaluate the realizability of our net deferred tax assets and perform an assessment of both positive and negative evidence. Based on our evaluation of all available positive and negative evidence, we determined, as of June 30, 2023 and December 31, 2022, that it is more likely than not that our net U.S. deferred tax assets will be realized. Due to estimates and the potential for changes in facts and circumstances, it is reasonably possible that we will be required to record a valuation allowance in future reporting periods that could have a material effect on our results of operations.


Recurring items cause our effective tax rate to differ from the U.S. federal statutory rate of 21%, including U.S. federal R&D credits, U.S. state tax rates, and stock-based compensation.


Beginning in 2022, certain research and development costs are required to be capitalized and amortized over a five-year period under the Tax Cuts and Jobs Act enacted in December 2017. This change will impact the expected U.S. federal and state income tax expense and cash taxes to be paid for our fiscal 2023.


The Company files income tax returns in the U.S. federal jurisdiction and in various state jurisdictions. Income tax returns for years prior to fiscal 2019 are no longer subject to examination by tax authorities.
