Owing money to the government can feel overwhelming, especially when penalties, interest, and collection activities start to build. If you're a taxpayer in Illinois facing severe financial hardship or long-standing unpaid tax debt, there may be a way to settle your balance for less than the full amount. The Illinois Offer in Compromise (OIC) is a state-administered compromise settlement program that allows eligible taxpayers to resolve past-due taxes, business taxes, and other tax liabilities by making a reasonable offer based on their ability to pay.
Unlike the IRS Offer in Compromise, the Illinois program is more limited in scope and governed by the Illinois Department of Revenue (IDOR) and its Board of Appeals. While the IRS considers multiple grounds for compromise—including doubt as to liability and effective tax administration—Illinois typically grants relief only in cases where the taxpayer’s financial condition suggests that full collection is unlikely.
This guide explains how the Illinois Department handles OIC requests, who qualifies, how to apply, and what to expect after submission. This article simplifies the process, whether you're dealing with back taxes, sales tax, withholding taxes, or business assets at risk of asset seizure, to help you take the first step toward resolving your tax debt and safeguarding your financial future.
The Illinois Offer in Compromise is a state tax relief option that allows qualifying taxpayers to settle their outstanding tax liability for less than the full amount owed. It is one of three formal options available to taxpayers disputing or resolving a final Illinois Department of Revenue (IDOR) assessment — alongside requesting an administrative hearing and paying under protest in circuit court. The OIC option is administered by the Illinois Department of Revenue's Board of Appeals (BOA) and is available to individuals and businesses who cannot fully pay their unpaid taxes.
Unlike the federal IRS Offer in Compromise, which accepts offers based on doubt regarding liability, collectability, or effective tax administration, the Illinois BOA's authority is narrower by design. The BOA's role is to ensure taxpayers are treated fairly and to provide relief where appropriate. In the context of an OIC, this means the BOA has authority to reduce a final tax liability only when it determines that full collection is unlikely, not to dispute or recalculate what is owed. If you believe the underlying tax liability itself is incorrect, that issue must be resolved separately through an administrative hearing or the Independent Tax Tribunal before an OIC becomes an available option.
The BOA does not have authority to redetermine a final tax liability or review administrative hearing decisions, Tax Tribunal decisions, or any court appeal of those decisions. This means the compromise process evaluates what IDOR can realistically recover from the taxpayer, not what the taxpayer believes they should owe.
To be considered, all tax returns must be filed, and no active appeals or audits can be pending. Offers are submitted using Form BOA-1, along with detailed financial information and documentation. Individuals and businesses — including those with income, business, sales, or withholding taxes — may apply.
The Illinois Offer in Compromise is not guaranteed, and acceptance is relatively rare. However, it provides a potential path to financial resolution for delinquent taxpayers who truly cannot pay their back taxes in full without the long-term burden of accumulating interest, penalties, or further enforcement actions.

The state considers several financial and situational factors when reviewing an offer. To be eligible, a taxpayer must typically demonstrate one or more of the following:
This applies to individuals and businesses, including those who owe income, business, sales, or other business taxes, such as withholding taxes or taxes tied to contractual payments. Business owners whose operations have closed may also apply.
Several factors can immediately disqualify an application, including
It's important to note that simply owing back taxes or being behind on payments does not make someone automatically eligible. Taxpayers must show that the Illinois Department cannot collect the full balance through standard enforcement tools like wage garnishment, bank account levy, or asset seizure.
Applying for an Illinois Offer in Compromise involves more than just filling out a form. Taxpayers must complete several steps, submit detailed financial documentation, and fully comply with state tax filing requirements. The Illinois Department of Revenue, through its Board of Appeals, reviews each application carefully and will not consider incomplete or non-compliant submissions.
Before applying, verify your total unpaid taxes, penalties, and interest. You can review your account by logging into MyTax Illinois or contacting the Illinois Department. Evaluate your income, expenses, and assets to determine whether your financial hardship is significant enough to justify an offer. Remember that the program is only for those who cannot pay their full tax liability.
All tax returns must be filed before you submit an offer. This includes personal income tax returns, business tax returns, and any other filings related to sales tax, withholding taxes, or other business taxes. If any returns are missing, your application will be rejected automatically.
Form BOA-1 is the official petition to request relief through the compromise settlement program. You must indicate that your petition is for an Offer in Compromise by checking the box in Section 5(b). In the form, provide
If you are represented by a tax attorney or other professional, include Form IL-2848 (Power of Attorney) with your submission.
Depending on your taxpayer type, you’ll also need to submit one of the following:
These multi-page forms require full disclosure of your financial information, including:
Inaccurate or incomplete financial disclosures can result in automatic rejection or denial later in the review process.
Attach the following documents to support your application:
This information helps IDOR evaluate your financial condition and determine whether to accept your offer.

You may also contact the Board of Appeals by phone at 312-814-3004, by fax at 312-814-3055, or by email at REV.BoardOfAppeals@illinois.gov. The Board of Appeals page on the Illinois Department of Revenue website provides additional guidance on the dispute and relief process.
If you’re facing aggressive collection actions—such as wage garnishment, bank account levy, or business asset seizure—you may request a Temporary Restraining Order (TRO) using Form BOA-1. This is not automatically granted and is approved at the discretion of the board’s chair. A TRO may pause specific other enforcement actions during the review period but does not prevent the department from issuing liens or pursuing other collection methods.
To be considered for an Illinois Offer in Compromise, submit several required forms and complete and accurate documentation of your financial situation. The Illinois Department of Revenue will not review your application unless all necessary forms are properly completed and supported with detailed records.
Here are the primary forms needed for individuals and businesses applying through the compromise settlement program:
To give the Illinois Department of Revenue a complete picture of your financial condition, you must also include:
Tax and Income Records:
Banking and Asset Information:
Debt and Expense Verification:
The more thorough and organized your financial documentation, the greater your chances of receiving a fair review. Missing records may cause delays or result in outright rejection.
Board Review and Decision (30–60 days): The Board of Appeals evaluates your case. A hearing may be held to clarify issues or explain circumstances if requested. The BOA has authority to reduce your final liability if it determines full collection is unlikely — but it does not have authority to redetermine your underlying tax liability or revisit prior administrative or tribunal decisions. The director of revenue provides final authorization on accepted offers.
While no official timeframe is guaranteed, most applications follow this general process:
The Board of Appeals considers multiple factors when deciding whether to accept an offer:
Once the review process is complete, there are several possible results:
Keep in mind that submitting an offer does not automatically pause enforcement. IDOR may continue specific other enforcement actions while your case is under review unless you've requested and received a Temporary Restraining Order.
Your OIC will not be processed if you are disputing a proposed assessment — whether through an administrative hearing with IDOR or before the Independent Tax Tribunal — or are currently under audit. For cases where the tax liability excluding penalties and interest exceeds $15,000, the Independent Tax Tribunal has jurisdiction; for smaller amounts, an administrative hearing with IDOR applies. Either dispute must be fully resolved before the BOA can consider your offer.
Avoiding these errors increases the chances of a successful offer and minimizes unnecessary enforcement such as wage garnishment, asset seizure, or referral to collection agencies.
An Offer in Compromise is not the only way to resolve an unpaid tax debt in Illinois. Because the Illinois Department of Revenue only accepts offers in rare cases involving genuine financial hardship, other resolution options may better serve many delinquent taxpayers. These alternatives may offer quicker approval, fewer documentation requirements, and more flexible repayment terms.
You may qualify for an installment agreement if you cannot pay your full tax bill immediately but can make regular monthly payments. This option allows you to pay back taxes over time, typically without submitting extensive financial information. You’ll still be responsible for paying penalties and interest, but enforcement actions may pause once your payment plan is approved.
The Illinois Department may occasionally agree to delay collection activities if you’re experiencing temporary financial difficulty. This informal relief doesn’t erase your tax liability but can provide short-term protection from collection actions like bank account levies or wage garnishment. You must still file all required tax returns and remain compliant.
Filing for bankruptcy may be an option for taxpayers facing overwhelming debt beyond just Illinois taxes. Depending on the circumstances, some tax debts may be discharged. However, bankruptcy has serious consequences and does not eliminate all types of taxes, such as recent sales tax or withholding tax obligations. You should consult a tax attorney or bankruptcy professional before pursuing this route.
Each alternative has its pros and cons. It’s essential to assess your financial situation honestly and choose the path that offers the most realistic and sustainable solution.
The Illinois Offer in Compromise process is complex, documentation-heavy, and highly selective. Even minor errors or omissions can result in rejection or delays. That’s why many taxpayers—especially those with significant tax debts or complicated financial situations—choose to work with a qualified tax professional.
You should consider hiring a tax attorney, an enrolled agent, or a certified public accountant (CPA) if you meet the following criteria:
A tax professional can help you avoid common mistakes, prepare your financial disclosure accurately, and ensure your petition is correctly submitted to the Illinois Department of Revenue. They can also help you determine whether another resolution method—such as a payment plan or penalty abatement based on reasonable cause—may be a better option. Professional guidance can differentiate between relief and continued collection action for many delinquent taxpayers.
Confirming that your application is complete, accurate, and realistic before submitting your Illinois Offer in Compromise is important. Use this checklist to avoid delays, rejections, or additional collection activities by the Illinois Department of Revenue.
By following these steps, you improve your chances of receiving relief through the compromise settlement program and reduce the risk of further enforcement or referral to collection agencies.
Your offer should reflect what the Illinois Department of Revenue could collect based on your financial condition. This includes your income, bank account balances, personal property, and business assets. The offer amount should be realistic and supported by documentation. Proposing an unreasonably low figure may result in immediate rejection, so it’s important to calculate carefully and include all relevant financial information.
The Illinois Offer in Compromise is only available for final, uncontested tax liabilities. If you believe your tax liability is incorrect, you must resolve that dispute first — either through an administrative hearing with IDOR or, if the liability excluding penalties and interest exceeds $15,000, by filing a petition with the Illinois Independent Tax Tribunal. The Board of Appeals does not have authority to redetermine your final tax liability or review administrative hearing or tribunal decisions. Only after the liability is final can you request compromise consideration through the BOA.
Submitting an offer does not automatically pause enforcement actions like a wage garnishment or bank account levy. To request a hold on collection activities, you must include a temporary restraining order request in Form BOA-1. Approval of a TRO is not guaranteed and is at the discretion of the board’s chair. Without one, the department may continue specific enforcement actions while your offer is under review.
Your full tax bill remains due if the Illinois Department denies your offer. You cannot appeal the Board of Appeals’ decision, and collection activities may resume. However, you can reapply later if your financial situation worsens or submit a more complete application. In the meantime, consider other options like a payment plan or requesting penalty abatement based on reasonable cause.
Your offer can include the total tax debt—base tax, interest, and penalties. Occasionally, the board may approve partial relief by waiving penalties and interest while requiring payment of the core tax balance. Supporting documentation must demonstrate financial hardship and explain why full payment of interest and penalties would be unreasonable or impossible.
It’s not required, but many taxpayers benefit from professional help. A tax attorney or enrolled agent can help you complete your forms, organize supporting documents, and negotiate effectively. This service is invaluable if you owe hefty business taxes, face liquor license revocation, or have been deemed personally responsible for business liabilities. A professional can also advise you on alternatives if the offer is unlikely.
An Offer in Compromise allows you to settle your tax debt for less than the full amount owed, while a payment plan involves repaying the entire balance over time. Payment plans are easier to obtain and require less documentation, but they do not reduce your tax liability. A payment plan is the first option explored for most delinquent taxpayers before considering a compromise.
