Several trusted Illinois programs offer free income tax preparation for low-to-moderate income families and older adults who may need assistance in filing their 2025 income taxes. The Internal Revenue Service (IRS), American Association of Retired Persons’ (AARP) Foundation Tax-Aide Program, the Ladder Up Tax Assistance Program (TAP), and the GetYourRefund Program provide free basic income tax return preparation with electronic filing to qualified individuals in select locations statewide. How taxpayer assistance is provided and when services are available varies by region, based upon volunteer capacity. Taxpayers can learn more about free tax assistance by visiting IDOR’s website tax.illinois.gov. Individuals with questions should contact IDOR’s Taxpayer Assistance Division at 800-732-8866. Taxpayers may also visit any of IDOR’s offices located in Chicago, Des Plaines, Fairview Heights, Marion, Rockford, and Springfield to receive assistance. Staff at these locations can help with any Illinois state income tax filing inquiries and are available on weekdays from 8:30 a.m. to 5:00 p.m.
