Illinois Announces Temporary Tax Amnesty from October 1, 2025 through November 17, 2025

The Illinois Tax Delinquency Amnesty Act provides Illinois taxpayers the opportunity to pay outstanding eligible tax liabilities and to have eligible penalties and interest forgiven on taxes paid in full during the amnesty period.

If you have an outstanding eligible tax liability, such as for sales or income tax, from tax periods ending after June 30, 2018 and prior to July 1, 2024 and you make full payment of the tax due by November 17, 2025, eligible penalties and interest will be waived. If you failed to file a tax return or incorrectly reported the liability due on a previously filed return for these tax periods, now is the time to file returns, make corrections, and pay the tax in full.
