Illinois extended a new amnesty period for all taxpayers between October 1, 2025, and November 15, 2025. This amnesty program allows taxpayers to report and remit taxes for periods between June 30, 2018 – July 1, 2024. Under this program, the Department of Revenue agrees to waive penalties and interest and will not seek civil or criminal penalties for any period where amnesty was granted as long as taxpayers pay all tax due for covered periods in the taxable period between October 1, 2025, and November 15, 2025. Taxpayers who are party to any pending criminal investigation or to civil or criminal litigation related to nonpayment, delinquency, or fraud in relation to Illinois state taxes will not be eligible.
Illinois’ amnesty program is particularly generous as it waives both penalties and interest for covered taxpayers, and taxpayers who qualify should absolutely consider applying. As states move toward more compliance, there is no reason not to take advantage of amnesty programs that will allow taxpayers to catch up on liabilities with as little out of pocket cost as possible.
