Yes, you can!
When you click the “Send my tax report” button in the menu of your app, you’ll see a drop-down menu that gives you an option to change the year of your report. You can change your report year from 2021 to any year (if you have information saved to your Stride account from those years--otherwise, your reports will be blank!).
