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 months ended April 30, 2022 and 2021 was 21.3% and 20.3%, respectively. The effective tax rate for the six months ended April 30, 2022 and 2021 was 21.0% and 20.5%, respectively.
Due to our share-based payment transactions, our income tax provision included a discrete tax benefit of $309 and $1,424 for the three and six months ended April 30, 2022, respectively, compared to $1,796 and $2,595 for the three and six months ended April 30, 2021, respectively.
