Using the Stride app to track your mileage?
The Stride app uses the current business mileage rate to calculate your mileage deduction, and will automatically update each year with the new business rate. Any miles recorded in 2020 will use the 2020 rate, and miles recorded in 2021 will use the 2021 rate.
