2025 Illinois Tax Amnesty
Taxpayers have the opportunity to pay outstanding eligible tax liabilities and have related penalties and interest forgiven, provided the taxes are paid in full during the amnesty period.
An eligible tax liability is tax debt due from periods ending after June 30, 2018, and prior to July 1, 2024.
Eligible tax liabilities and returns must be paid and filed in full October 1, 2025, through November 17, 2025, to qualify for the waiver of penalty and interest.
