Sonoma and Napa counties - District 10

NOTE: If one or more of your tax returns were was destroyed by the October 2017 wildfires in Sonoma and Napa counties, you can get copies of your federal tax return from the IRS at no charge. Details are here. Similarly, you can get copies of your California tax returns from the FTB at no charge. Details for that are here.

In Sonoma County, during the 2018 tax season, the Tax-Aide program of the AARP Foundation will operate eleven sites, from Cloverdale to Petaluma, and from Sebastopol to the city of Sonoma. In Napa County, the program will operate at one site, in the city of Napa.

For our locations, dates, and times during the 2018 tax season, which is from February through mid-April 2018, you can download or view this file. For locations outside our district, go to or call 888-227-7669.

Before you visit one of the regular sites during the tax season, please make sure that you're bringing all the documents that you need for us to prepare your taxes. You'll find a comprehensive list here. (If you just have a tax question, feel free to just drop in.)

The United Way of the Wine County also sponsors a number of sites in Sonoma County that offer free tax preparation. For more information, and to make appointments, call 2-1-1.

From May to November 2018, the Tax-Aide program will be operating a tax clinic for taxpayers who have a tax return they need to file, have a tax return that they want to amend, want assistance in understanding or responding to a notice from the IRS or California Franchise Tax Board, or just have a tax question or concern. 

Our program is entirely run by volunteers - approximately 90 - and charges no fees. The focus is on low and moderate-income households headed by those 50 and older, but the program serves people of all ages, and has no specific income limit.

(If you're interested in volunteering with our program, we'd love to have you join us! More information can be found here.)
