AARP Foundation Tax-Aide, the nation’s largest free, volunteer-run tax assistance and preparation program, started in 1968 with just four volunteers at one site. When in full operation, over 35,000 volunteers in all 50 states and the District of Columbia serve approximately 4,800 Tax-Aide sites. AARP Foundation Tax-Aide volunteers are trained and IRS-certified each year to ensure they know about and understand the latest changes and additions to the U.S. Tax Code.
