11. Income Taxes

For the three months ended March 31, 2022, we did not recognize provision for income taxes due to our pre-tax book loss as we continue to record a full valuation allowance on our deferred tax assets considering our cumulative losses in prior years and forecasted losses in the future. For the three months ended March 31, 2021, we recorded a provision for income tax of $1.8 million. The provision for income tax for the three months ended March 31, 2021 was estimated using our effective tax rate on our year-to-date income (loss). We estimated a state tax liability over our pre-tax income (loss) for 2021, which is primarily due to revenue recognized for the Lilly Agreement. We did not estimate a provision for federal income taxes due to the sufficient net operating loss carryforwards that were generated prior to enactment of the Tax Cuts and Jobs Act, as well as our ability to utilize significant research and development credit carryforwards.
