Tax Preparation Assistance

Tax Day Event. First come first serve. We will help you file your simple return if time permits. Already filed? Come and enjoy FREE popcorn, hotdogs, nachos and more.

Please bring:

  • -Photo ID for each person on your return
  • -Social security card or ITIN for each person on your return
  • -W-2s from all jobs
  • -Last year’s tax return
  • -Child care provider information
  • -Health coverage information (Forms 1095-A, B or C)
  • -Saving and/or checking account and routing numbers.

Due to time and other constraints, we can not help you with more complicated tax returns such as most Schedule C’s, renters income, foreclosure, debt cancellation and more. If we can not help you with your taxes, we can provide you an extension form or download one below.

Every year, hundreds of Tuolumne and Amador County families are eligible for free income tax assistance.

If you earned $54,000 or less, we can prepare and file your taxes free. 

LAST DAY TO FILE- TUESDAY, APRIL 18th. If you need an extension, download the form here.

In partnership with the IRS, ATCAA’s Tax Program offers free tax preparation for qualified recipients between January and April in Amador and Tuolumne Counties through the Volunteer Income Tax Assistance (VITA) program.

Each year, there are many households who are not required to file a return but may benefit greatly from filing. There are many tax credits available such as the Earned Income Tax Credit, Child and Dependent Care Credit, Education Tax Deduction, and many more which can contribute to a resident receiving a tax refund.
