Income taxes Income taxesFor the three months ended March 31, 2022, the Company recorded minimal income tax expense and for the three months ended March 31, 2021, the Company recorded no income tax expense. For the three months ended March 31, 2022, the Company's effective tax rate was less than 1% and for the three months ended March 31, 2021, the Company’s effective tax rate was 0%. The Company’s effective tax rate differs from the U.S. federal statutory rate of 21% primarily because the Company’s losses have been fully offset by a valuation allowance due to uncertainty of realizing the tax benefit of net operating losses ("NOLs”) for the three months ended March 31, 2022 and for the year ended December 31, 2021.
