Illinois Payroll Tax Default Prevention Checklist
Introduction
Illinois payroll tax is money withheld from employee wages and collected by employers on behalf of the state. This refers specifically to Illinois income tax withheld from paychecks, administered by the Illinois Department of Revenue. The Department expects employers to file payroll tax returns quarterly and remit collected funds in accordance with assigned payment schedules.
When payroll taxes are not filed or paid on time, the state issues notices and may take collection action. Understanding what triggers payroll tax issues and what steps to take helps prevent penalties, interest charges, and enforcement actions that can affect your business operations and finances.
What This Issue Means
Payroll tax default occurs when an employer fails to file a required payroll tax return, fails to pay collected payroll taxes by the deadline, or both. This is different from owing income tax as an individual. Employers act as tax collectors for the state—they gather taxes from employee wages and send that money to Illinois on a scheduled basis.
When this collection and remittance system breaks down, the state identifies the employer as delinquent and begins a formal process to recover the funds.
Why the State Requires This
The Illinois Department of Revenue requires all employers to file payroll tax returns quarterly.
Payment schedules are assigned separately and depend on withholding amounts: a monthly
payment schedule (due by the 15th of the following month) or a semi-weekly payment schedule
(due Wednesday for Wednesday through Friday withholding and Friday for Saturday through
Tuesday withholding).
New taxpayers start on the monthly schedule. Taxpayers who exceed $12,000 in withholding during a quarter or look-back period move to the semi-weekly schedule. Payroll taxes are mandatory collections, not optional business expenses. The state’s primary purpose in pursuing unpaid payroll taxes is to collect funds that legally belong to the state and represent employee withholdings.
What Happens If This Is Ignored
If payroll tax returns are not filed or payments are not made, the Illinois Department of Revenue issues written notices to the employer’s last known address. These notices request compliance and outline the amount owed. If the employer does not respond or remit payment within a specified timeframe, the state may escalate collection efforts.
Potential escalation includes levies against the business owner’s or responsible person’s wages
(the owner’s employer withholds up to 15% of gross wages, with at least 10 days’ notice), bank account levies (with a 20-day hold before transfer to the Department), liens placed against business or personal property (enforceable for 20 years), personal liability assessments against responsible persons (100% of unpaid tax, penalties, and interest), or referral to contracted collection agencies. The longer the issue remains unaddressed, the more penalties and interest accumulate.
What This Does NOT Mean
Receiving a payroll tax notice does not automatically mean the state has filed a lien or seized assets. It does not mean criminal charges have been filed. The notice is a formal request for compliance and the first step in the collection process, not the final one. At this stage, the employer can respond, clarify any errors, or arrange payment.
Steps to Address Payroll Tax Issues
Step 1: Locate and Review All Notices
Gather every notice, letter, or document received from the Illinois Department of Revenue related to payroll taxes. Do not discard or ignore any correspondence. Check the physical mailbox and business mail, search email for messages from the Department, look for notices postmarked within the last one to two years, and note the date, amount, and period covered on each notice.
Step 2: Verify Business Registration Status
Confirm that your business is properly registered with the Illinois Department of Revenue and that contact information is current and correct. Visit the Department website, search your business name or tax identification number, check that the address, email, and phone number on file match your current information, and update contact information if incorrect or outdated.
Step 3: Gather Payroll Records and Tax Forms
Collect all payroll documents related to the tax period in question, including records showing wages paid, taxes withheld, and deposits made. Locate quarterly payroll tax returns filed or not filed, examine bank statements showing any deposits to the Department, gather payroll records for employees on payroll during that period, and collect copies of any wage and tax statement forms.
Step 4: Calculate the Actual Amount Owed
Review the notice to identify the specific tax period, type of tax, and the amount claimed by the state. Compare this to your payroll records. Note the tax period stated in the notice, identify the type of payroll tax (Illinois income tax withholding), calculate the amount based on your payroll records, and note any differences between the state’s figure and your calculation.
Step 5: Determine if There Are Valid Reasons for the Discrepancy
If your records do not match the state’s notice, identify whether the difference results from an error, a missing payment, a filed return with a calculation error, or a payment that was not properly credited. Review each quarterly return to confirm it was filed, check if payment was sent but possibly not posted to the correct account, identify any payroll calculation errors you may have made, and note any periods when no employees were on payroll.
Step 6: Contact the Illinois Department of Revenue
Reach out to the Department using the contact information on the notice or the official state website. Call 1-800-732-8866 or 217-782-3336, have your business tax identification number and notice information ready, explain the situation clearly, ask what documents the Department needs from you, request clarification on the exact amount owed and why, and ask about available options for payment or dispute resolution.
Step 7: Request a Payment Plan if Applicable
If you cannot pay the full amount immediately, ask about payment installment plans. The
Department offers payment plans with standard terms: the default plan length is 12 months, with the option to extend to 24 months. For amounts over $15,000, additional financial documentation may be required using Form EG-13-I for individuals or Form EG-13-B for businesses. Apply online through MyTax Illinois for instant approval if you qualify, or submit
Form CPP-1 by mail. All returns must be filed current to qualify.
Step 8: Document All Communication
Keep detailed records of all conversations, emails, and correspondence with the Department.
Write down the name of the person you spoke with, the date, and the time of the call. Note what was discussed and any commitments made. Keep copies of all emails and letters sent to or received from the Department. Store documents in one organized file for reference.
Step 9: Submit Any Requested Documents
If the Department requests additional information or documentation, submit it promptly by the deadline specified. Send documents by the method requested, include a cover letter identifying your business and the tax period in question, keep a copy of everything you submit, request confirmation of receipt, and do not assume documents were received without confirmation.

Step 10: Verify Payment Was Posted Correctly
If you submit a payment, confirm that the Illinois Department of Revenue has received and properly applied it to your account. Wait for a receipt or confirmation from the Department.
Follow up within two to three weeks if no confirmation is received. Ask the Department to confirm the payment was posted to the correct account and tax period. Request an updated balance statement showing the current amount owed.
What Happens After You Respond
After you contact the Illinois Department of Revenue and provide the requested information or payment, the Department processes your submission and sends a confirmation or status update. If a payment is made, the state applies it to the account and may issue a revised notice showing the updated balance. If the issue requires investigation or additional review, the
Department may send follow-up requests.
Some processing timelines are specified: overpayment refunds receive interest if not processed within 90 days; personal liability assessments allow 60 days to protest; bank levies hold funds for 20 days; wage levies require at least 10 days’ notice; and MyTax Illinois payment plans offer instant approval for qualifying taxpayers.
Common Mistakes to Avoid
Many employers discard notices, thinking they are duplicate requests or errors, but each notice represents formal state communication and should be carefully reviewed.
Submitting payment without clearly identifying which business account and tax period it applies to may result in incorrect posting; always include your tax identification number and specific tax period on all payments and correspondence.
If your business contact information changes, update your registration information promptly with the state to ensure you receive notices. Early contact often provides more options than waiting until collection action is underway.
Verify the notice against your actual payroll records before dismissing it, as the state’s calculation may be correct. Without copies of returns, payments, and correspondence, proving payment or disputing a notice becomes difficult.
Frequently Asked Questions
What is the difference between a payroll tax notice and a payroll tax lien?
A notice is a request for payment or compliance. A lien is a legal claim against a business's assets that the state files after other collection efforts fail to resolve the debt. A notice comes first. A lien is a more serious enforcement action that prevents you from selling or refinancing business assets without satisfying the debt. Liens are enforceable for twenty years.
Can I dispute a payroll tax notice if I believe it is wrong?
Yes, the state expects employers to review notices against their records. If you find a discrepancy, contact the Department with documentation of the error. Employers who receive certain notices (Notice of Deficiency, Notice of Tax Liability, Notice of Personal Liability, Notice of
Claim Denial) have specific protest rights.
You can either request an administrative hearing with the Department, file a petition with the
Illinois Independent Tax Tribunal within 60 days if the dispute amount exceeds $15,000, waive the administrative hearing and go directly to circuit court by paying under protest using Form
RR-374, or file a petition with the Board of Appeals for penalty and interest relief.
If I cannot pay the full amount owed, what are my options?
The Illinois Department of Revenue offers payment installment plans. Standard terms include a default plan length of 12 months, with a possible extension to 24 months. For amounts over
$15,000, additional financial documentation is required. All outstanding liabilities are included in the same plan. All returns must be filed current to qualify. Apply through MyTax Illinois for instant approval if you qualify, or submit Form CPP-1 by mail.
Will penalties and interest continue to accrue while I work on resolving the issue?
Yes, interest continues to accrue on unpaid balances. Penalties may also apply. Resolving the issue as quickly as possible limits the total amount owed. You may request penalty abatement for reasonable cause by providing a detailed explanation of the delay and supporting documentation. For returns filed more frequently than annually, if the failure is non-fraudulent and no other failure occurred in the prior two years, the late-filing penalty is abated.
Does the state offer penalty abatement or relief from interest charges?
The Illinois Department of Revenue provides detailed guidance on penalty abatement.
Taxpayers who filed or paid late and made a good-faith effort to comply may request abatement of the late-filing or late-payment penalty for reasonable cause. You must provide a detailed explanation of the cause of the delay and supporting documentation. Interest generally cannot be abated except in very limited circumstances.
