AARP offers free tax assistance through specially trained volunteers in the Tax-Aide program. Although anyone can use Tax-Aide — AARP membership isn't required, and there are no age or income restrictions — the program is especially suited to low- to moderate-income taxpayers who are 50 and older. Here's what you need to bring. See image below for how to set an appointment.
