The AARP Tax-Aide is a free volunteer-run tax preparation and assistance service available to taxpayers with low and moderate income, with special attention to those age 60 and older.

AARP Tax-Aide's nearly 36,000 volunteers work at 6,000 sites nationwide to serve 2.5 million customers annually. All volunteers are trained and IRS-certified, with most providing tax counseling and return preparation via e-filing. Locally over 100 volunteers work during tax season at 19 Westchester sites including libraries and community centers. This is a program of the AARP Foundation that offers free tax counseling to taxpayers across the United States.
