Welcome to AARP Tax-Aide at the Oro Valley Library, 1305 West Naranja Drive, Oro Valley, AZ 85737. Please click on a choice below to make a tax preparation appointment.  If you are waiting to receive any of your tax documents, please schedule your appointment for later in the season. After making your appointment, you will need to go by the Oro Valley Library to pick-up a Tax-Aide envelope. Please follow the instructions inside while completing the forms. During your appointment, a certified Tax-Aide volunteer will review your tax documents for completeness and ask any questions required before preparing your tax return. Once your tax return has been completed, a second certified Tax-Aide volunteer will complete a quality review of your tax return and explain the results with you. After you approve and sign your completed tax return, our Tax-Aide site will e-file your return.
