Can I add in my past mileage from before using Stride?

Yes! 

To add your past mileage, you can use the "Add Mileage" button in your app that shows up after pressing the yellow "+" on your home screen.

You will be able to input a "Single Trip" or "Multiple Trips" at a time. You can add in a bulk number of miles that you drove before using Stride by using the "Multiple Trips" option.

Just be sure you are only adding in mileage and expenses for which you have proper documentation so that you can back up the deductions!

Note for all users:

If you have incomplete records or forgot to keep track of your miles throughout the year, have a look at this article for more information on properly adding past mileage, What to do if you didn't track your mileage.
