9. Income Taxes
The income tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate as adjusted for discrete items arising in that quarter. The effective income tax rate was (0.0)% and (0.1)% for the nine months ended October 31, 2021 and 2020, respectively. The effective tax rate differs from the U.S. statutory rate primarily due to the full valuation allowances on the Company’s net domestic deferred tax assets and impact of foreign tax rate differential.
On March 27, 2020, the CARES Act was enacted and signed into U.S. law to provide economic relief to individuals and businesses facing economic hardship as a result of the COVID-19 pandemic. Changes in tax laws or rates are accounted for in the period of enactment. The income tax provisions of the CARES Act did not have a significant impact on our current taxes, deferred taxes, or uncertain tax positions.
