6. Income taxes
The Company is subject to federal and state income taxes in the United States. The tax provision for interim periods is determined using an estimate of the Company's annual effective tax rate ("AETR"). The Company updates its estimated AETR on a quarterly basis and, if the estimate changes, a cumulative adjustment is made.
As of March 31, 2025 and December 31, 2024, the Company recorded a full valuation allowance against net deferred tax assets and intends to continue maintaining a full valuation allowance on these net deferred tax assets until there is sufficient evidence to support the release of all or a portion of these valuation allowances. Release of some or all of the valuation allowance would result in the recognition of certain deferred tax assets and an increase in deferred tax benefit for any period in which such a release may be recorded. However, the exact timing and amount of any valuation allowance release are subject to change, depending upon the level of profitability that the Company is able to achieve and the net deferred tax assets available.
For the three months ended March 31, 2025, the Company's effective income tax rate of 2.9% differed from the statutory federal income tax rate of 21% primarily due to state and local tax expense and losses for which no tax benefit is recognized as such amounts are fully offset with a valuation allowance. For the three months ended March 31, 2024, the Company's effective income tax rate of 16.9% primarily represents the state and local tax expense, offset by the benefit of federal research and development credits.
The Company assesses its income tax positions and records tax benefits for all years subject to examination based upon its evaluation of the facts, circumstances, and information available as of the reporting dates. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, the Company has recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, tax benefit has been recognized in the Company's financial statements. |
