Falling behind on taxes can feel overwhelming, but Illinois is offering taxpayers a second chance. The Illinois Tax Delinquency Amnesty Act of 2025 creates a limited-time opportunity for individuals and businesses to pay off overdue state taxes without having to shoulder the added burden of penalties and interest. By giving taxpayers with outstanding obligations a chance to come forward voluntarily, the state hopes to encourage both compliance and recover money that might otherwise be tied up in costly collections or court cases.
The program applies to a wide range of taxes. Most state taxes administered by the Illinois Department of Revenue (IDR) qualify if they were due for periods ending after June 30, 2018, and before July 1, 2024. Certain franchise taxes and license fees handled through the Secretary of State's office are also eligible if they fall within the period of June 30, 2019 through June 30, 2025. Remote retailers who owe sales taxes have a separate window, covering tax periods from January 1, 2021 through June 20, 2026. For most taxpayers, the key amnesty window will run from October 1 through November 15, 2025, although remote retailers will have until the fall of 2026.
To take part in the program, taxpayers must do two things: file any missing or amended returns for the eligible periods and pay the full amount of tax owed during the amnesty window. If both steps are completed, the state will forgive penalties and interest connected to the debt. This relief is only available if the tax itself is unpaid; balances consisting solely of penalties or interest are not covered by the program.
Eligibility is fairly broad, and even taxpayers currently under audit or in the middle of a dispute with the IDR or the Illinois Independent Tax Tribunal can participate, provided they withdraw their protest and pay what they owe in full. In some cases, taxpayers under the protection of federal bankruptcy court may need additional approval before joining the program.
Although eligibility is broad, it's important to note that not every type of tax or fee qualifies for amnesty under the program. Property taxes, estate taxes, and most local government taxes fall outside of the program's scope since they are not collected by the IDR. Motor Fuel Use Taxes (MFUT), International Fuel Agreement (IFTA) liabilities, and certain non-tax fees (e.g., licensing costs, permits, motor fuel violations, etc.) are also excluded. Additionally, lien filing and release fees, bad check penalties, collection agency fees, and certain audit-related penalties will not be forgiven. In short, amnesty applies to penalties and interest related to unpaid state tax debt, not to unrelated fees or already-settled accounts.
For Illinois taxpayers carrying unresolved tax debt, this amnesty program is essentially a fresh start. It allows people to resolve their obligations at a much lower cost, avoid the stress of collections or legal action, and re-establish good standing with the state. But the opportunity won't last forever. Once the amnesty window closes, penalties and interest will return, and in some cases, enforcement may become even more aggressive. If you believe that you might qualify for the amnesty program, now is the time to gather your records, review your tax history, and prepare to act quickly when the amnesty window opens.
