If you would like advice, please call 888-227-7669 or send an email to with your name, phone number, and a brief description of your tax-related problem.

If you're interested in volunteering at one of our sites in San Mateo County, we'd love to hear from you. Our more than 100 volunteers work in one of our 17 sites throughout the county helping their neighbors prepare their taxes.  We provide IRS certified training (in January) and equipment (a notebook computer and printer), at no cost to volunteers. AARP Foundation reimburses volunteers for mileage. AARP membership is not required.

We operate at 17 locations in San Mateo County. Each site is open one day a week, Monday through Saturday, usually between 9 a.m. and 5 p.m. A tax counselor is required to work at least at one of these sites from February 1st through April 15th, usually about 10 sessions. Besides tax counselors we also have open positions for Client Facilitaor, Greeter, and management positions which require less training.
