Illinois Sales Tax Enforcement Actions Checklist
Introduction
Illinois sales tax enforcement actions are formal notifications issued by the Illinois Department of
Revenue (IDOR) when a business has not filed required sales tax returns, has not paid sales
tax owed, or is suspected of sales tax non-compliance. These actions represent a significant escalation from routine filing requirements and signal that the state is beginning a structured collection or enforcement process.
Enforcement actions can include demand notices, liens, levies, or other collection procedures designed to recover unpaid taxes and penalties. Understanding what an enforcement action entails and how it progresses is essential, as ignoring these notices can result in additional penalties, interest, asset seizure, and legal consequences that compound over time.
The state issues these actions when standard notices and payment reminders have not produced results, making prompt response critical to avoiding further complications in your tax account.
What This Issue Means
An Illinois sales tax enforcement action is a formal demand from the state for payment of unpaid sales tax, penalties, and interest. It indicates that IDOR has moved beyond routine collection notices and is now actively pursuing debt recovery through defined enforcement procedures.
The action may take several forms, including a Notice of Tax Liability, a demand for immediate payment, a notice of intent to file a tax lien, or a notice of levy against your bank account or other assets.
This represents a transition from the filing and payment stage into the enforcement and collection stage. At this point, the state considers the account past standard collection attempts and is applying formal legal mechanisms to recover the outstanding balance.
Why the State Issued This or Requires This
The Illinois Department of Revenue issues enforcement actions when businesses fail to respond to earlier notices and fall behind on sales tax obligations. Common administrative triggers include unreported sales, uncollected sales tax from customers, failure to remit collected taxes to the state, and repeated non-filing of required returns.
In many cases, IDOR has already sent multiple notices requesting payment or return filing before an enforcement action is issued. The state is required by law to collect taxes owed and follows specific procedures when standard collection methods have not resolved the debt. IDOR has discretion to pursue collection actions based on various factors, including amount owed, taxpayer history, and collection efforts.
What Happens If This Is Ignored
Failing to respond to an Illinois sales tax enforcement action results in the state taking more aggressive collection steps. These may include filing a tax lien against your business or personal property, levying funds from your bank account, or garnishing other income sources.
Penalties and interest continue to accrue on the unpaid balance, increasing the total amount owed.
Illinois law establishes criminal penalties for willful sales tax violations. Willful attempts to evade sales tax are Class 4 felonies when the amount is less than $500, with higher classifications for larger amounts.
Willful failure to file or pay constitutes a criminal offense under Illinois statutes. IDOR’s standard collection procedures include liens, levies, wage garnishment, asset seizure, license revocation, and referral to contracted collection agencies.
What This Does NOT Mean
An enforcement action does not automatically mean your assets will be seized immediately or that criminal charges have been filed. It also does not mean you have exhausted all options for resolving the debt or that negotiation is impossible.
Receiving an enforcement notice does not automatically result in a tax lien being filed on your property—although a notice of intent to lien may be included in the enforcement action itself.
The enforcement action is a formal notice of collection procedures, not a final judgment or a guarantee of immediate seizure.
Steps to Take After Receiving an Enforcement Action
Step 1: Read the Entire Enforcement Notice Carefully and Identify the Key
Information
Note the tax year or periods involved. Identify the amount of tax, penalties, and interest owed.
Look for any deadline stated in the notice. Locate the IDOR office or department issuing the action. Find contact information and the case or account number.
Step 2: Verify the Accuracy of the Information in the Notice
Check your sales tax returns for the periods listed. Compare the amount stated in the notice to your records. Look for any mathematical errors or duplicate assessments. Note any periods you believe you reported correctly. Set aside documentation that supports your position.
Step 3: Determine Whether You Filed Sales Tax Returns for the Periods
Listed
Gather copies of any returns you filed for those periods. Check your filing records or confirmation numbers. Identify any returns that were not filed on time. Note whether any returns were filed but not paid. Keep copies of filing confirmations for reference.
Step 4: Review Your Payment History for the Periods Involved
Locate bank records showing sales tax payments to IDOR. Check for any partial payments or adjustments. Identify any payments applied to other tax types by mistake. Note the dates and amounts of all payments made. Determine whether payments were made on time.
Step 5: Document Your Current Business Status
Determine whether your business is still operating. Identify whether you have changed ownership or legal structure. Check your IDOR account registration status. Note any changes in business location or contact information. Gather documentation of current business operations if applicable.
Step 6: Contact IDOR to Understand the Exact Amount and Basis for the
Enforcement Action
Call the telephone number listed in the notice. Ask for a full explanation of how the amount was calculated. Request clarification on which returns are unpaid or unfiled. Ask whether the notice is based on an assessment or a return you filed. Request written confirmation of the exact amount and due date. Get the name and direct contact information of the IDOR representative you speak with.
Step 7: Gather All Relevant Financial and Business Records
Collect bank statements for the periods in question. Gather point-of-sale records or sales documentation. Locate customer invoices and sales receipts. Gather records of sales tax collected from customers. Collect any amended returns or corrected filings you may have submitted. Organize records by date and period for easy reference.
Step 8: Determine Whether You Can Pay the Full Amount Owed
Calculate your available cash or liquid assets. Determine whether you can access credit or loans to pay. Consider whether full payment is feasible within the deadline. If full payment is possible, arrange for immediate payment to IDOR. Request written confirmation once payment is received.
Step 9: If You Cannot Pay in Full, Contact IDOR Immediately to Discuss
Payment Options
Call the number in the enforcement notice as soon as possible. Explain your financial situation.
Ask about payment plans or installment agreements. Request information about penalty abatement or relief options. Ask whether you can request a stay of enforcement action during negotiations.
Step 10: If You Believe the Assessment or Enforcement Action Is Incorrect,
Request an Explanation in Writing
Send a letter to IDOR describing why you believe it is incorrect. Reference the specific notice and account number. Explain the basis for your disagreement. Provide supporting documentation with your letter. Keep a copy of your letter for your records. Ask for a written response within a reasonable timeframe.
Step 11: Do Not Ignore Deadlines Stated in the Enforcement Notice
Mark the deadline date on your calendar. Set a reminder several days before the deadline.
Contact IDOR before the deadline if you need more time. Request written confirmation of any deadline extension. Plan to respond before the deadline, even if you cannot pay in full.

Step 12: Keep Detailed Records of All Communication with IDOR
Note the date, time, and name of each IDOR representative you contact. Document what was discussed and any agreements made. Save all written correspondence, emails, and letters.
Keep records of any payments made and confirmation numbers. Maintain a timeline of all actions taken on your account.
What Happens After This Is Completed
After you contact IDOR and provide information or payment, the state will review your response and determine the next steps. IDOR does not publish specific timeframes for processing payments, issuing confirmations, or responding to enforcement action responses. If you pay the full amount owed, IDOR will process the payment and apply it to your account.
If you request a payment plan, IDOR will evaluate your situation and may issue an agreement outlining the terms. If you dispute the assessment, IDOR will review your documentation and
may issue a written response explaining its position or offering to modify the amount owed. The state may proceed with lien filing, levy, or other enforcement collection procedures if it receives no response or the deadline passes without action.

Frequently Asked Questions
What is the difference between an enforcement action and a regular bill or invoice?
An enforcement action is a formal legal notice issued after standard collection efforts have failed. It signifies that the state is transitioning to enforcement procedures such as lien filing or asset seizure. A regular notice or bill is an earlier reminder to file a return or make a payment.
If I receive an enforcement action, does that mean a tax lien has already been filed?
Not necessarily. A notice of intent to file a lien and an actual filed lien are different. The notice may warn you that a lien will be filed if you do not respond by a specific date. To check for tax liens filed by IDOR in Illinois, search the State Tax Lien Registry maintained by the Illinois
Department of Revenue. The Illinois Secretary of State’s UCC search system includes federal tax liens but not state tax liens enforced by IDOR.
Can I stop an enforcement action by requesting a payment plan?
Requesting a payment plan may delay or stop enforcement proceedings, but the state is not obligated to offer one. IDOR evaluates payment plan requests based on financial hardship and the amount owed. Contact IDOR immediately to discuss this option.
What if I believe the sales tax assessment is incorrect?
Contact IDOR and request a detailed explanation of how the amount was calculated. Illinois provides clear procedures for disputing assessments. Taxpayers can request administrative hearings through IDOR’s Office of Administrative Hearings or file petitions with the Illinois
Independent Tax Tribunal within 60 days of receiving a Notice of Tax Liability or deficiency notice. If you disagree, provide documentation supporting your position.
Can an enforcement action affect my ability to get a business license or operate my business?
If you owe past due tax and have a business or professional license, IDOR may notify you and the appropriate licensing authority to begin revocation or suspension proceedings or to stop the issuance or renewal of your business or professional license. For sales tax specifically, IDOR may request a hearing to revoke your sales tax certificate.
If I pay the enforcement action amount, does that clear all penalties and interest?
If you pay the full amount stated in the enforcement notice, that satisfies the debt. If additional periods are unpaid or if new penalties accrue after the notice date, those would be separate.
Always confirm with IDOR that the payment resolves the entire matter.
What happens if I contact IDOR but cannot pay immediately?
Contact IDOR and explain your financial situation. The state may allow you time to arrange payment, set up a payment plan, or temporarily pause enforcement action. There is no guarantee of relief, but communicating before the deadline is always preferable to missing it entirely.
