Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
The Company is subject to U.S. federal and state income taxes as a corporation. The Company’s tax provision and the resulting effective tax rate for interim periods is determined based upon its estimated annual effective tax rate adjusted for the effect of discrete items arising in that quarter.
The effective tax rate for the three months ended March 31, 2023 and 2022 was zero as the Company has incurred continuous operating losses. The Company recorded no income tax provision or benefit during the three months ended March 31, 2023. The Company recorded an income tax benefit of less than $0.1 million during the three months ended March 31, 2022.

On August 16, 2022, the Inflation Reduction Act was enacted in the U.S. and introduced a 15% alternative minimum tax based on the financial statement income of certain large corporations (“CAMT”), effective January 1, 2023. There was no impact on the Company’s provision for income taxes from the CAMT for the three months ended March 31, 2023.
Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Due to the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against its otherwise recognizable net deferred tax assets
