Income taxes
We record our interim provision for income taxes based on our estimated annual effective tax rate, as well as certain items discrete to the current period. The effective tax rate for the three and nine months ended July 31, 2021 was 21.2% and 20.8%, respectively. The effective tax rate for the three and nine months ended July 31, 2020 was 8.9% and 16.0%, respectively.
Due to our share-based payment transactions, our income tax provision included a discrete tax benefit of $570 and $3,165 for the three and nine months ended July 31, 2021, respectively. Our income tax provision included a similar discrete tax benefit of $11,373 and $14,048 for the three and nine months ended July 31, 2020, respectively.
During the three months ended July 31, 2020, we recorded a favorable adjustment to unrecognized tax benefits of $443. In addition, during the three months ended July 31, 2020, there was an increase of $5,664 in unrecognized tax benefits and, if recognized, the gross unrecognized tax benefits would be offset against assets currently recorded in the Consolidated Balance Sheet.
