The Illinois Department of Revenue (IDOR) is urging individuals and businesses to take advantage of the 2025 Illinois Tax Amnesty Program, which allows taxpayers to settle outstanding state tax liabilities without paying penalties or interest.
Authorized by the Illinois Tax Delinquency Amnesty Act, the program forgives penalties and interest on eligible past-due taxes paid in full during the amnesty period. It applies to taxes due for periods ending after June 30, 2018, and before July 1, 2024. Full payments must be made between October 1 and November 17, 2025.
“This initiative demonstrates Governor Pritzker’s ongoing commitment to supporting taxpayers, particularly those facing financial hardships or economic uncertainties,” said Illinois Department of Revenue Director David Harris. “We encourage both individuals and business owners to use the amnesty period to resolve outstanding tax liabilities and achieve greater financial stability.”
Illinois has offered similar tax amnesty programs in 2003, 2010, and 2019, recouping nearly $360 million during the 2019 initiative for state and local coffers.
Taxpayers who failed to file or underreported their liabilities for eligible periods can file original or amended returns and pay the taxes owed. All eligible outstanding taxes must be paid in full during the amnesty window to qualify.
Payments can be made online at mytax.illinois.gov using a checking or savings account, by mail, or in person at IDOR offices. “We encourage taxpayers to make separate payments for each tax liability being paid, but if they choose to make one combined payment, they must clearly identify each tax liability being paid by tax type, tax period, and amount, so their payments can be applied correctly,” Harris said.
