|Income Taxes||Income Taxes
The Company computes its year-to-date provision for income taxes by applying the estimated annual effective tax rate to year-to-date pretax income or loss and adjusts the provision for discrete tax items recorded in the period. For the three months ended September 30, 2021 and 2020 the Company reported no provision for income taxes, which resulted in an effective tax rate of zero percent. For the nine months ended September 30, 2021 and 2020 the Company reported no provision for income taxes, which resulted in an effective tax rate of zero percent. The provision for income taxes varied from the tax computed at the U.S. federal statutory income tax rate of 21% for the periods presented primarily due to changes in the Company’s valuation allowance, state taxes, and, the tax effects of stock-based compensation.
The Company is subject to income tax in the U.S. as well as other tax jurisdictions in which the Company operates. The Company’s U.S. operations have resulted in losses, and as such, the Company maintains a valuation allowance against all U.S. deferred tax assets. While the Company believes itscurrent valuation allowance is appropriate, the Company assesses the need for an adjustment to the valuation allowance on a quarterly basis. The assessment is based on all available positive and negative evidence including past results of operations, forecasted earnings, tax planning strategies, and all sources of future taxable income. In the event the Company determines that it will be able to realize all or part of its net deferred tax assets in the future, all or part of the valuation allowance will be released in the period in which the Company makes such determination. The release of all or part of the valuation allowance against deferred tax assets may cause greater volatility in the effective tax rate in the periods in which it is released.
The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
