Illinois Unfiled Return Request: Complete Guide

Receiving an Illinois Unfiled Return Request from the Illinois Department of Revenue can be stressful, especially if you were unaware of any filing issues. This notice indicates that the department’s records show you may not have filed required income tax returns or that you have outstanding eligible tax liabilities requiring attention. This notice serves as an official reminder that you must take corrective action to bring your account into compliance.

The Illinois Department issues these notices to maintain accurate taxpayer accounts and ensure compliance with state individual income tax requirements.

Most situations can be resolved quickly by reviewing your tax records and taking action through your MyTax Illinois account. By following the instructions in the notice, submitting missing documents, or setting up a payment plan, you can eliminate future problems and restore your account to good standing. This guide explains how the process works, what each notice means, and how to respond effectively.

Before responding, taxpayers should understand what the Illinois Department of Revenue means by this notice and why it is relevant for their account.

Definition and Purpose under the Illinois Department of Revenue

Primary purpose: The notice ensures taxpayers promptly address unfiled returns or resolve unpaid income tax before the department proceeds with collection.
Legal authority: The Illinois Department uses data from employers, federal tax reports, and financial institutions to verify unfiled or underreported returns.
Taxpayer obligation: Individuals must file all required income or sales tax reports accurately and by their due dates to avoid collection actions.

Common Elements Found in an Illinois Unfiled Return Request

Although each notice's format varies, most letters share similar sections explaining what action taxpayers must take.

Header details: The top section lists your Illinois account number, notice ID, mailing date, and tax year or filing period referenced.
Summary of issue: The body explains whether you failed to file a return, underpaid, or owe additional tax and related penalties.

Why the Illinois Department Sends an Income Tax Notice

Understanding why the Illinois Department sends this notice can help taxpayers determine the right response and avoid future issues. These letters are not always signs of wrongdoing but rather a prompt to review your records and ensure compliance.

Balance Due or Underpayment of Income Tax

The most common reason for receiving an Illinois Unfiled Return Request is an outstanding balance on your account.

Partial payments: Some taxpayers make estimated or partial payments but fail to pay the full tax debt by the due date.
Department adjustments: The Illinois Department of Revenue may adjust a return based on information from the IRS or employer reports, increasing the amount owed.
Unpaid penalties: If you owe a prior-year tax, the department may combine the amounts and apply an estimated payment penalty.

Unfiled or Missing Individual Income Tax Returns

Occasionally, a notice results from missing individual income tax returns.

Filing oversight: Taxpayers may forget to file for one or more years, especially if their income changes or they move out of Illinois.
Federal return data: The department often receives IRS information showing you had income but did not submit a corresponding Illinois return.
System tracking: The Illinois Department uses automated systems to match federal and state records to identify missing returns or filing errors.

Data Matching and Verification Issues

The Illinois Department relies on several third-party data sources to detect inconsistencies and confirm taxpayer information.

Employer reporting: Employers submit wage data and tax withholdings that the department compares with filed returns.
Bank and financial data: Financial institutions report dividends, interest, and other income that may trigger a filing requirement.
Identity verification letter: Taxpayers may receive a separate letter asking them to verify their identity before the department processes the return or payment.

Follow-Up Letters for Ongoing Tax Debt

If the taxpayer does not respond or the issue remains unresolved, the Illinois Department continues the process by sending follow-up notices.

Reminder notices: The department sends additional letters to remind taxpayers of unresolved issues or unpaid tax debt.
Compliance monitoring: Nonresponsive individuals may face enforcement through liens, levies, or wage garnishment.
Department tracking: The Illinois Department of Revenue records all related notices in the taxpayer’s Illinois account for future reference.

Consequences of Ignoring a Notice

After receiving a notice, taxpayers must comprehend the possible consequences of not taking action. Under state law, ignoring an Illinois Unfiled Return Request can lead to serious financial and administrative consequences.

Penalties, Interest, and Estimated Payment Penalty

The longer the taxpayer delays resolving the notice, the more penalties and interest accumulate.

Late filing penalty: The Illinois Department of Revenue may charge a penalty based on a percentage of the unpaid tax for late returns.
Late payment penalty: Interest compounds daily, and an estimated payment penalty applies if taxes are underpaid or payments are missed.
Interest calculation: Interest continues until the balance is paid in full, though certain amnesty period programs may allow interest to be forgiven for qualified taxpayers.

Property Liens, Garnishments, and Other Collection Actions

If the taxpayer ignores collection letters, the Illinois Department may escalate enforcement to secure payment of outstanding liabilities.

Tax liens: A lien gives the department a legal claim to your property or assets until the tax debt is fully satisfied.
Wage garnishment: The department may contact an employer to withhold a portion of wages for unpaid tax balances.
Bank levies: Funds from financial accounts may be seized to cover the unpaid balance, often after multiple attempts to contact the taxpayer.

Long-Term Effects on Outstanding Eligible Tax Liabilities

Failure to respond can create lasting financial problems beyond the original tax debt.

Credit impact: Liens and collection actions appear on credit reports, affecting loan eligibility and future borrowing opportunities.
Collection duration: The Illinois Department of Revenue can continue collection indefinitely for unfiled or unpaid returns.
Loss of relief options: Taxpayers who ignore notices may lose eligibility for programs designed to eliminate penalties or negotiate settlement agreements.

How to Respond to an Illinois Unfiled Return Request

Responding to an Illinois Unfiled Return Request promptly helps you minimize penalties and restore your standing with the Illinois Department of Revenue. Taking the proper steps can prevent further enforcement actions and protect your financial stability.

Step 1: Review the Letter and Verify Details

Read your notice carefully to confirm the tax year and filing type, identify the amount, and determine whether the issue involves missing returns, unpaid balances, or data discrepancies. Always verify that your name, address, and Illinois account number match your records before further action.

Step 2: Gather and Review Your Tax Records

Collect all documents relevant to your notice to confirm what was filed and paid. Review previously filed state and federal returns, including W-2s, 1099s, and employer wage reports, to verify reported income and withholdings. Confirm payments through canceled checks or payment vouchers to ensure the department’s findings are accurate.

Step 3: Confirm Filing Requirements

Determine whether you must file a return for the year in question. Illinois residents must file if their income exceeds the filing threshold, while nonresidents must file for income earned. Part-year residents must file for the portion of the year they lived in Illinois.

Step 4: Respond Electronically or by Mail

Submit your response through your MyTax Illinois account or by mail, following the instructions on your notice. Electronic submissions receive faster confirmation and secure processing. If mailing, include the notice, completed forms, and a payment voucher if applicable. Then, retain copies or postal receipts for your records.

Step 5: Keep Copies and Follow Up on Your Response

Maintain organized records of all documents, correspondence, and payment confirmations in case verification or appeals become necessary. After submitting your response, log into your MyTax Illinois account or call the department to confirm receipt. Continue monitoring your account to ensure no additional notices or unresolved balances remain.

Resolution Options for Illinois Tax Debt

If you cannot pay your balance in full, the Illinois Department of Revenue offers several resolution options to help taxpayers meet their obligations and avoid enforcement. Each program has specific eligibility requirements and benefits.

Payment Plan Options

A payment plan allows taxpayers to pay their balance in monthly installments through the department’s secure system.

Online enrollment: Log into MyTax Illinois to request a payment plan directly and receive immediate approval confirmation.
Flexible terms: The Illinois Department adjusts payment amounts based on your total debt and monthly income.
Automatic payments: Set up recurring payments from your bank account to avoid missed due dates or additional penalties.

Penalty and Interest Forgiven During Amnesty Periods

The department periodically offers programs that allow eligible taxpayers to pay their principal tax due and have penalties or interest forgiven.

Amnesty opportunity: The amnesty period allows taxpayers to eliminate accrued penalties by paying the tax owed in full.
Eligibility check: Taxpayers must not have active criminal charges related to fraud or tax evasion to qualify for relief.
Payment process: Full payment must be made during the designated period, typically between September and November of the announced year.

Offer in Compromise and Appeals

Taxpayers facing severe financial hardship or disputes may petition the Board of Appeals for relief or settlement.

Filing petition: Submit a written request to the Board of Appeals with documentation explaining why full payment would cause undue hardship.
Review process: The board evaluates your income, assets, and living expenses to determine whether a compromise or waiver applies.
Decision outcome: If approved, the department may reduce or eliminate portions of your tax debt, interest, or related penalties.

Guidance for Taxpayers Experiencing Financial Hardship

Taxpayers unable to pay financially can explore temporary relief through alternative options.

Currently not collectible: The department may suspend collection if paying would prevent you from meeting essential living expenses.
Documentation required: Applicants must submit detailed financial statements and proof of hardship to qualify for relief.
Ongoing review: The department periodically re-evaluates hardship cases to determine whether collection can resume.

Always review the instructions provided in your letter to your MyTax Illinois account to confirm that the department received your response before the deadline passes.

What if I dispute the Illinois Department of Revenue’s findings?

If you believe the department's assessment of your tax records and supporting documentation is incorrect, gather your tax return explanation or file a petition for review with the Board of Appeals. Ensure you respond within the stated timeframe to preserve your right to dispute the notice and avoid further enforcement actions.

Can Illinois garnish my wages for unpaid tax debt?

The Illinois Department of Revenue can garnish wages if your tax debt remains unresolved. Before taking this step, the department will issue a notice and allow time for a response. You may prevent garnishment by arranging a payment plan, resolving filing issues, or contacting the department directly to negotiate an alternative resolution.
