Received a Notice of Proposed Deficiency, tax lien notice, bank levy, wage levy, or business tax notice from Illinois? These notices can carry important deadlines and collection risk, so they shouldn't be treated like an ordinary bill. IDOR can levy up to 15% of gross wages and file liens in the Statewide Tax Lien Registry.

These are not normal bills.

Deadlines and collection risk matter.

Illinois Tax Relief Overview

Owing Illinois state taxes is different from owing the IRS. The Illinois Department of Revenue (IDOR) has its own rules, deadlines, and collection tools. Federal tax relief strategies do not automatically apply to Illinois state tax debt.

Key Illinois Tax Facts You Need to Know

Illinois does have an Offer in Compromise (OIC) program—processed by the Board of Appeals. Unlike some states that offer no OIC option, Illinois allows settlement for less than the full amount due to financial or medical hardship, with Director approval required.

Wage levy is calculated using a state-specific formula based on gross wages — generally, the lesser of 15% of gross wages or the amount by which disposable earnings exceed 45 times the federal minimum wage. This is a different approach from the exempt-amount method the IRS uses, and it affects how much is taken from your paycheck.

Two-track appeal system: for matters within Tribunal jurisdiction, disputes of more than $15,000 go to the independent Illinois Independent Tax Tribunal (IITT). Matters not within IITT jurisdiction — including disputes of $15,000 or less and certain excluded tax types — go through IDOR's Office of Administrative Hearings (OAH).

Statewide Tax Lien Registry — online since January 1, 2018. Liens are enforceable for 20 years.

100% responsible person liability for trust taxes under 35 ILCS 735/3-7.

Depending on your tax situation, you may need one or more of the following services in Illinois:

A payment plan to pay over time (Form CPP-1; ACH debit may be required and is recommended)
An Offer in Compromise to settle for less than you owe (financial/medical hardship basis)
An appeal if you received an assessment you disagree with (IITT for disputes over $15,000; OAH for $15,000 or less)
Penalty relief if penalties and interest make the balance harder to pay
Lien resolution or levy help if collection actions have started
Filing help if you have unfiled Illinois tax returns

If you run a business in Illinois and owe sales tax (retailers' occupation tax) or withholding tax, the stakes are higher. These are trust fund taxes — money collected or withheld that belongs to the state of Illinois. IDOR can pursue 100% personal liability against responsible persons under 35 ILCS 735/3-7.

What the Illinois Department of Revenue Can Do to Collect

If you owe Illinois state taxes and do not address the balance, IDOR has a broad range of collection tools. Not every case reaches the most serious actions, but unresolved tax debt can lead to escalating collection steps over time.

Add Penalties and Interest

Late filing penalties can apply, and late-payment penalties vary depending on when payment is made and whether audit conditions apply; collection penalties can also apply. Together, penalties and interest add up quickly. Interest continues to accrue until paid in full under 35 ILCS 735/3-3. Penalty abatement may be available for reasonable cause under 35 ILCS 735/3-8.

Send Collection Notices

IDOR sends a series of notices before taking enforced collection action. Ignoring these notices leads to more serious steps. The Notice of Proposed Deficiency and Notice of Final Assessment are critical documents with strict 60-day appeal deadlines.

File a Tax Lien in the Statewide Tax Lien Registry

Since January 1, 2018, IDOR files tax liens in the Statewide Tax Lien Registry, an online statewide system under 35 ILCS 750/. The Registry is searchable at no charge, and Illinois states there are no additional filing or release fees through the Registry—though taxpayers may still be responsible for applicable lien-related fees depending on context. Liens are enforceable for 20 years and can affect credit, property sales, and business operations.

Levy Wages and Bank Accounts

IDOR may issue a wage levy under a state-specific formula based on gross wages (generally the lesser of 15% of gross wages or the amount by which disposable earnings exceed 45 times the federal minimum wage). IDOR may also levy bank accounts and other financial assets. A 10-day notice is required before levy action.

Seize Real and Personal Property

IDOR has the authority to seize real estate, automobiles, and business assets. A 10-day notice is required before seizure. Most seized property cannot be sold for at least 20 days (perishable items may be sold within 24 hours).

License Revocation and Other Actions

IDOR may pursue professional license non-renewal or revocation, certificate of registration revocation, liquor license revocation, corporate charter revocation with the Secretary of State, and lottery license revocation. IDOR may also refer cases for prosecution.

‍

Illinois Tax Payment Plans

If you cannot pay your Illinois state tax balance in full, a payment plan (installment agreement) may help you resolve tax debt over time. Illinois uses Form CPP-1, Installment Payment Plan Request. Plans are not automatic and are based on your ability to pay.

Important: Interest and Penalties Continue During Payment Plans

Even while your Illinois payment plan is active, interest and penalties continue to accrue on the unpaid balance. A payment plan does not stop interest or penalty accumulation, nor does it erase the underlying tax liability. If you default, the entire balance becomes due immediately, and IDOR may take enforcement action, including a bank levy or wage garnishment.

Key Conditions for Illinois Payment Plans

Requirement	Details

‍

Businesses must be current on prior filings and demonstrate the ability to stay current on new obligations while paying old tax liabilities. Payment plans commonly cover individual income tax, corporate income tax, sales tax (retailers' occupation tax), and other state tax obligations for tax years 2022, 2023, 2024, and 2025.

‍

Illinois Offer in Compromise (OIC)

Yes, Illinois has an Offer in Compromise program—a key difference from states that don't offer an OIC option. Illinois OICs are processed by the Board of Appeals (BOA) at IDOR, and only the director of revenue is authorized to compromise debts due the state following BOA review.

Illinois OIC Key Facts

Basis: Financial hardship, medical hardship, or other demonstrable hardship
Processed by: Board of Appeals (BOA) — three members appointed by the Director
Form: Form BOA-1, Board of Appeals Petition
When to file: After the tax liability has become final (all administrative hearings, Tax Tribunal decisions, and court proceedings ended or time expired)
Approval: At least 2 of 3 board members must agree; then the Director must approve
Finality: Decisions by the Board of Appeals are final and cannot be appealed
Waiver effect: Filing BOA-1 extends the statute of limitations for enforcement while the Board has jurisdiction and for 30 days thereafter
Not for ICB: Offers based on inability to pay must not be filed with the Informal Conference Board (ICB); they must go to the Board of Appeals

How the Illinois OIC Process Works

Liability must be final — all administrative hearings, IITT decisions, and court proceedings must be ended, or the time to appeal must have expired.
File Form BOA-1 — submit the Board of Appeals Petition with supporting financial and hardship documentation.
Board review — the three-member Board reviews your petition, financials, and basis for compromise.
Board vote — at least 2 of 3 members must agree to recommend a settlement.
Director approval — only the director of revenue can authorize the compromise following BOA review.

‍

Illinois Penalty Relief

Penalty relief is different from a payment plan. A payment plan lets you pay over time; penalty relief asks Illinois to reduce or remove penalties when allowed under state rules.

Illinois penalties may be abated upon a determination of "reasonable cause" under 35 ILCS 735/3-8 and 86 Ill. Admin. Code 700.400. The standard is whether the failure to file or pay was due to reasonable cause, measured by whether the taxpayer acted in good faith and with ordinary business care and prudence.

Factors IDOR Considers for Reasonable Cause

Clarity of the law and its interpretation
Taxpayer's education, experience, and knowledge
Reliance on the advice of a tax professional (may justify abatement)
Taxpayer's filing history
Extraordinary circumstances (death, serious illness, natural disaster, fire)

Examples of Reasonable Cause

Death or serious illness of the person solely responsible for filing
Natural disaster (flood, fire)
Destruction of records with documentation (e.g., fire department report)
Reliance on erroneous written advice from the Department (20 ILCS 2520/4(c))

Important Requirements

Determination is made on a case-by-case basis, taking into account all pertinent facts and circumstances.
Interest relief is limited and fact-specific. The Board of Appeals may waive penalties and interest for reasonable cause. Whether interest can be reduced in a particular case depends on the specific facts, so it's worth discussing your situation directly.
Penalty abatement is processed by the Board of Appeals (after liability is final) or through the department's normal channels.

‍

Illinois Penalty Types

Penalty	Rate	Statute
Late Filing	2% of tax due, up to $250	35 ILCS 735/3-3
Late Payment	2%–20% of tax due, depending on the timing of payment and whether audit conditions apply	35 ILCS 735/3-3
Collection Penalty	$30 if liability under $1,000; $100 if $1,000 or more	35 ILCS 735/3-4.5
Fraud	No statute of limitations	35 ILCS

‍

Penalty Relief vs. Payment Plan

A penalty waiver and a payment plan are separate processes. A payment plan does not automatically remove penalties. Penalty relief must be requested separately and approved based on reasonable cause under 35 ILCS 735/3-8. Even if penalties are waived, the underlying tax and interest must still be paid.

‍

Illinois Tax Appeals: IITT and OAH

Illinois has a two-track appeal system depending on the amount in dispute and the type of tax involved. Choosing the right track and meeting the deadline is critical — missing an appeal deadline can severely limit your ability to challenge an assessment.

Illinois Appeal Deadlines

Both tracks generally have a 60-day deadline from the date of the notice (30 days for IFTA). The deadline is strict. Missing it can make the assessment final and much harder to challenge.

Track 1: Illinois Independent Tax Tribunal (IITT) — For Disputes Over $15,000

The Illinois Independent Tax Tribunal (IITT) is a separate body from IDOR, established in 2012 under 35 ILCS 1010/. This is a key feature of Illinois tax law: unlike many states, where appeals stay within the revenue department, Illinois created an independent tribunal for larger disputes.

Feature	Details
Jurisdiction	Tax liability excluding penalty and interest of more than $15,000, or penalties and interest only totaling more than $15,000
Statute	35 ILCS 1010/ (Illinois Independent Tax Tribunal Act of 2012)
Established	2012 (effective August 28, 2012)
Filing Fee	$500 (waivable for financial hardship)
Deadline	60 days from the date of the notice (or 60 days after a discretionary late-hearing grant)
Filing Methods	In person at Springfield or Chicago offices; certified or registered mail; messenger or private parcel delivery; electronic filing (when permitted)
Address	Room N506, 160 N LaSalle St, Chicago IL 60601
Phone	312-814-4285
Fax	312-814-4768
IDOR Answer	IDOR must file its answer within 30 days after receipt of Tribunal notification
Website	taxtribunal.illinois.gov

‍

Cases the IITT Does NOT Hear
The IITT has specific exclusions. It does NOT hear:

Property tax assessments; tax liability proposals (notices of proposed deficiency); finalized collection actions (liens, levies, revocations); informal administrative appeals; administrative subpoenas; and certain excise and specialty taxes, including Adult Use Cannabis Cultivation Privilege Tax, Aviation Fuel Tax, Bingo Tax, Cannabis Purchaser Excise Tax, Cigarette Machine Operators' Occupation Tax, Charitable Games Tax, Liquor Taxes, Parking Excise Tax, Pull Tabs Tax, Real Estate Transfer Tax, Private Party Vehicle Use Tax, and Tire User Fee.

Track 2: IDOR Office of Administrative Hearings (OAH) — For Disputes of $15,000 or Less

For smaller disputes — and for matters not within IITT's jurisdiction — appeals are handled by the Office of Administrative Hearings (OAH) within IDOR. While not independent like the IITT, the OAH provides a formal hearing process for deficiency assessments, claim denials, and registration denials.

Feature	Details
Jurisdiction	Tax liability excluding penalty and interest of $15,000 or less
Form	Form AH-4 (or Form EAR-14 for income tax)
Deadline	60 days from the date of notice (30 days for IFTA)
Submission	Email: REV.AdminHrgs@Illinois.gov (preferred); Mail: Administrative Hearings, MC 5-550, 101 West Jefferson Street, P.O. Box 19014, Springfield, IL 62794-9014
Types Heard	Deficiency assessments, claim denials, registration denials
Not Heard	OIC cases, reasonable cause cases, cases over $15,000

‍

Informal Conference Board (ICB). Before a formal appeal, taxpayers may use the Informal Conference Board (ICB) using Form ICB-1. The deadline is 60 days from the date the notice is issued. You must sign a waiver of the statute of limitations in Step 5. Form ICB-2 may be used to settle disputes with legitimate uncertainty. Do not use the ICB for an OIC based on inability to pay — those go to the Board of Appeals.

Circuit Court Appeals. Taxpayers may also appeal to an Illinois circuit court by paying under protest using Form RR-374 under 30 ILCS 230/2a and 230/2a.1 (State Officers and Employees Money Disposition Act).

60-Day Appeal Deadline — Do Not Miss It. The appeal deadline is generally 60 days from the date of the notice for both IITT and OAH appeals. Missing this deadline can make the assessment final and severely limit your options. Do not wait.

‍

Review My Illinois Notice and Appeal Deadline

If you received an Illinois tax assessment notice, review the 60-day deadline before doing anything else. Missing an appeal deadline can limit your options. We can help you determine whether to appeal to the IITT (over $15K) or OAH (under $15K).

Illinois Tax Liens and the Statewide Tax Lien Registry

Illinois tax liens work differently from most states. Since January 1, 2018, IDOR files tax liens in the Statewide Tax Lien Registry, an online system under 35 ILCS 750/. Before 2018, liens were filed with individual county recorders.

How the Illinois State Tax Lien Registry Works

Feature	Details
System	Statewide Tax Lien Registry — online
Established	January 1, 2018 (P.A. 100-22)
Statute	35 ILCS 750/ (State Tax Lien Registration Act)
Before 2018	Liens were filed with each county recorder
Current Practice	Filed in the State Tax Lien Registry, not with each county
Filing Fees	No additional filing or release fees through the Registry itself; taxpayers may still be responsible for applicable lien-related fees depending on context
Duration	20 years, enforceable
Effect	In most cases, you cannot sell or transfer property until the past-due amount is resolved
Credit Impact	Negative impact on credit rating
Release	Requires full payment of the past-due amount. Immediate release available if paid by guaranteed remittance (cash, cashier's check, USPS money order)
Error Release	If a lien is issued in error, IDOR will issue a release
Search	tax.illinois.gov/programs/taxlienregistry.html
Subscription	Available: $500 new, $50 renewal

‍

Payoff and Release Information

Contact rev.lien@illinois.gov or 217-785-5299. Immediate release requires payment by guaranteed remittance (cash, cashier's check, USPS money order). Taxpayers may be responsible for any applicable filing and release fees.

Collection Statute

The collection period can range from 2 years to 20 years or longer, depending on when the lien was filed, the judgment was entered, or other enforcement actions occurred.

‍

Illinois Bank Levy and Wage Garnishment

IDOR has broad levy authority. Illinois can levy wages, bank accounts, contractual payments, accounts receivable, notes receivable, and other assets. A 10-day notice is required before levy action.

Illinois Wage Levy Uses a Gross-Wage Formula

Illinois calculates wage levies differently from many other jurisdictions. Rather than applying a flat percentage to disposable earnings, Illinois wage garnishment is based on gross wages using a state-specific formula — the lesser of: (1) 15% of the gross amount paid for the week, or (2) the amount by which disposable earnings exceed 45 times the federal minimum hourly wage. This is a different approach from the exempt-amount method the IRS uses for federal wage levies.

Illinois Wage Levy Details

Feature	Details
Maximum	The lesser of 15% of gross wages or the amount exceeding 45x the federal minimum wage
Form	EDC-111-W Wage Levy Calculation Worksheet
Duration	Remains effective until tax liability is paid in full
Employer	Employer must continue to withhold until IDOR releases the levy
Frequency	Payment to IDOR at least once per month
Exemption	Salary/wages of officers/employees of states other than Illinois are exempt
Priority	Child support and prior garnishments take precedence over a tax levy

‍

Illinois Bank Levy Details

Available: Yes — IDOR may levy bank accounts and financial assets
Notice: 10-day notice required before levy
Authority: 35 ILCS 735/ (implied from levy authority)
Scope: May levy on contractual payments, accounts and notes receivable, evidences of debt, and bond interest
Federal employees: May levy on federal employees, including officers and elected officials, per 5 U.S.C. 5520a

Wage Levy vs. Bank Levy

Feature	Wage Levy	Bank Levy
Target	Your paycheck	Your bank account
Amount	Up to 15% of gross wages (formula-based)	Full account balance (up to liability)
Duration	Continues each pay period until paid in full	One-time at the time of service
Notice Required	10-day notice	10-day notice

‍

Illinois Unfiled Tax Returns

If you have not filed Illinois tax returns for one or more years, that can block most tax debt relief options. IDOR may estimate your tax and issue assessments based on those estimates — sometimes higher than what you actually owe.

Filing accurate returns can sometimes reduce an incorrect balance, but do not rush or file incomplete returns. It's better to get returns for 2022, 2023, 2024, or 2025 prepared correctly with the right income, deductions, and Illinois credits.

Why Filing Matters

Unfiled returns block payment plan eligibility — all returns must be filed to qualify.
IDOR may issue substitute returns with higher tax than you actually owe.
Penalty relief generally requires all returns to be filed.
Failure to file can keep assessment exposure open in many cases; once liability is finalized, collection periods vary based on enforcement history.

Illinois Statute of Limitations

Situation	Limitations Period
General assessment	3 years from the date the return was filed
Substantial omission (>25% of income)	6 years
Reportable transactions (non-disclosed)	6 years
No return filed	No statute of limitations
Fraud	No statute of limitations
Refund claims	3 years from the date the return is filed, or 1 year from the date tax paid, whichever is later
Collection (general)	2 to 20 years or longer, depending on enforcement history
Federal changes	2 years from the date the notification was due

‍

Illinois Business, Sales Tax, and Payroll Tax Debt

Business tax debt carries a higher risk than individual income tax debt. In Illinois, sales tax (Retailers' Occupation Tax under 35 ILCS 120/), income withholding tax (under 35 ILCS 5/), and other trust taxes carry heightened collection consequences from IDOR, including personal liability exposure for responsible persons. These are trust fund taxes — money collected or withheld that belongs to the state.

Responsible Person Warning: 100% Personal Liability

Under 35 ILCS 735/3-7(a), any officer or employee with control, supervision, or responsibility for filing returns and making payment of trust tax who willfully fails to do so faces 100% personal liability for the unpaid tax, including interest and penalties.

Who can be held liable? Any person who had authority and control over business funds and participated in the decision to prefer other creditors while taxes went unpaid, including officers, employees, members, or anyone with control over disbursements.

Willfulness standard: Intentional, knowing, voluntary acts, or reckless disregard for obvious or known risks. Does not require bad purpose or intent to defraud.

Burden of proof: The Department's certified record is prima facie correct; the burden shifts to the taxpayer to disprove willfulness (Branson v. Dept. of Revenue, 168 Ill.2d 247 (1995)).

Key points:

The personal liability penalty equals 100% of the tax unpaid, including interest and penalties.
Each responsible person is individually liable.
Applies to both sales tax (35 ILCS 120/) and withholding tax (35 ILCS 5/1002(d), cross-referencing 735/3-7).
Amounts withheld are held in a special fund in trust for IDOR per 35 ILCS 5/705.

Sales Tax (Retailers' Occupation Tax) Is a Trust Tax

Illinois sales tax, officially the Retailers' Occupation Tax under 35 ILCS 120/, is a trust tax—amounts collected are held in trust for the state. IDOR can pursue collection through liens, levies, and personal assessment of responsible persons.

Withholding Tax Requirements

Illinois employers must withhold state income tax from employee wages and remit it to IDOR. Amounts withheld are held in a special fund in trust for the Department under 35 ILCS 5/705. If a business fails to pay withholding taxes, responsible persons may be held personally liable under 35 ILCS 735/3-7.

Illinois Income Tax Rate

Individual: 4.95% flat rate (under 35 ILCS 5/)

Corporate: 7.00%, plus a 2.5% replacement tax on net income

Illinois Sales Tax Debt

Unpaid retailers' occupation tax can lead to license revocation, penalties, enforced collection action, and 100% personal liability for responsible persons under 35 ILCS 735/3-7.

Illinois Payroll / Withholding Tax Debt

Withholding tax that is not remitted can trigger 100% personal liability under 35 ILCS 735/3-7 and enforced collection by IDOR.

Illinois Taxpayer Rights

Illinois has a Taxpayers' Bill of Rights under 20 ILCS 2520/ that provides important protections:

Right to call IDOR for help resolving tax problems
Right to privacy and confidentiality
Right to respond within specified time periods
Right to appeal decisions
Right to credit or refund for overpayment
Right to abatement based on erroneous written information from the Department

Damages: Taxpayers may recover up to $100,000 if IDOR intentionally or recklessly disregards tax laws (20 ILCS 2520/5). Attorney fees may be recoverable if the taxpayer prevails and IDOR made an assessment without reasonable cause (20 ILCS 2520/7).

Frequently Asked Questions

Can I get a payment plan for Illinois state taxes?

Yes. Illinois offers installment payment plans through IDOR using Form CPP-1. ACH debit may be required and is recommended. Financial statements (Form EG-13-I for individuals or EG-13-B for businesses) are required documentation for balances over $15,000. Interest and penalties continue during the plan. All returns must be filed, and current taxes must be paid on time. Plans are not automatic and depend on your financial condition and ability to pay. Default makes the entire balance due immediately.

Does Illinois have an Offer in Compromise program?

Yes. Illinois has an Offer in Compromise program processed by the Board of Appeals (BOA). Only the director of revenue is authorized to compromise tax debt following BOA review. The basis is financial hardship, medical hardship, or other demonstrable hardship. Use Form BOA-1 after the tax liability has become final. At least 2 of 3 board members must agree, then the director must approve. Decisions are final and cannot be appealed. Filing a BOA-1 extends the statute of limitations for 30 days from the date the board has jurisdiction.

Does an Illinois payment plan stop penalties and interest?

No. A payment plan lets you pay over time, but interest and penalties continue to accrue on the unpaid balance during the plan. Penalties already assessed remain unless separately waived through Illinois' reasonable cause process under 35 ILCS 735/3-8. The plan does not erase the underlying tax debt. If you default, the entire balance becomes due immediately, and IDOR may take enforcement action.

Can I appeal an Illinois tax assessment?

Yes. Illinois has a two-track appeal system. For a tax liability of $15,000 or less (excluding penalty and interest), file Form AH-4 or EAR-14 with the IDOR Office of Administrative Hearings (OAH) within 60 days. For a liability of more than $15,000, file with the Illinois Independent Tax Tribunal (IITT) within 60 days, with a $500 filing fee (waivable for financial hardship). The IITT does not hear property tax matters or certain excise tax types, which are handled through other channels. Missing the 60-day deadline can result in the assessment becoming final.

Can Illinois file a tax lien?

Yes. Since January 1, 2018, Illinois has filed tax liens in the Statewide Tax Lien Registry, an online system under 35 ILCS 750/. Before 2018, liens were filed with county recorders. Illinois tax liens are enforceable for 20 years and can affect credit, property sales, and transfers. Release requires full payment of the past-due amount. Contact rev.lien@illinois.gov or 217-785-5299 for payoff information. The registry can be searched at tax.illinois.gov/programs/taxlienregistry.html.

Can Illinois garnish wages for state taxes?

Yes. Illinois can levy, or garnish, wages for state tax debt. Illinois uses a state-specific formula based on gross wages — generally the lesser of 15% of gross wages or the amount by which disposable earnings exceed 45 times the federal minimum wage. This differs from the exempt-amount approach the IRS uses for federal wage levies. IDOR uses Form EDC-111-W for wage levy calculations. A 10-day notice is required before levy. The wage garnishment remains in effect until the full tax liability is paid, and the employer must continue to withhold until IDOR releases the levy. Child support and prior garnishments take precedence.

Can Illinois levy my bank account?

Yes. Illinois can levy bank accounts and other financial assets. IDOR must provide 10 days' notice before levying. Bank levies can freeze and seize funds up to the amount of the tax liability. Illinois may also levy on contractual payments, accounts receivable, notes receivable, and evidence of debt. Federal employees, including officers and elected officials, may also be subject to levy under 5 U.S.C. 5520a.

Can Illinois waive penalties?

Yes. Under 35 ILCS 735/3-8, penalties may be abated for reasonable cause. The standard is good faith plus ordinary business care and prudence. Factors include the clarity of the law, the taxpayer's experience, reliance on a tax professional's advice, filing history, and extraordinary circumstances (such as death, serious illness, natural disaster, or fire). Interest relief is more limited and fact-specific; the Board of Appeals may consider waiving penalties and interest for reasonable cause, and eligibility depends on the specific circumstances. Penalty abatement is processed by the Board of Appeals or through the Department's normal channels.

What if I have unfiled Illinois tax returns?

Unfiled returns can block most resolution options. IDOR may estimate your tax and issue assessments that are higher than what you actually owe. Filing accurate returns can sometimes reduce an incorrect balance. Do not rush or file incomplete returns — get them prepared correctly with the right income, deductions, and Illinois credits. All returns must be filed before applying for a payment plan or penalty relief.

What if my Illinois tax debt is from sales tax or payroll withholding?

Sales tax (retailers' occupation tax) and payroll withholding debt carry heightened risk because these are trust fund taxes. Under 35 ILCS 735/3-7, any officer or employee with control, supervision, or responsibility for filing returns and paying trust tax who willfully fails to do so faces 100% personal liability. Willfulness includes reckless disregard for obvious risks. The Department's certified record is prima facie correct, shifting the burden to the taxpayer to disprove willfulness (Branson v. Dept. of Revenue, 168 Ill.2d 247 (1995)).

How do I appeal an Illinois tax assessment?

Illinois uses a two-track system: (1) for disputes of $15,000 or less, file Form AH-4 or EAR-14 with the IDOR Office of Administrative Hearings (OAH) at REV.AdminHrgs@Illinois.gov within 60 days; (2) for disputes of more than $15,000, file with the Illinois Independent Tax Tribunal (IITT) at 160 N LaSalle St, Chicago, within 60 days. The IITT requires a $500 filing fee (waivable for hardship) and is independent from IDOR. You can also use the Informal Conference Board (Form ICB-1) before a formal appeal, but do not use the ICB for OIC cases.

Does filing an Illinois OIC stop collection?

Filing a BOA-1 (Board of Appeals Petition) for an Offer in Compromise extends the statute of limitations for enforcement while the Board has jurisdiction and for 30 days thereafter. This does not necessarily stop all collection activity during the review period. The Board of Appeals process applies only after the tax liability has become final — after all hearings, tribunal decisions, and court proceedings have ended or the time to pursue them has expired.

What is the difference between the IITT and OAH?

The Illinois Independent Tax Tribunal (IITT) is a separate, independent body from IDOR created in 2012. It hears appeals where the tax liability exceeds $15,000, and it has a $500 filing fee. The IDOR Office of Administrative Hearings (OAH) is within IDOR and hears appeals of $15,000 or less. Both generally have a 60-day deadline. The IITT is independent; the OAH is an internal IDOR process. The IITT does not hear property tax cases, certain excise taxes, or finalized collection actions.

What is the Illinois Statewide Tax Lien Registry?

The Statewide Tax Lien Registry is an online system established on January 1, 2018, under 35 ILCS 750/. Before 2018, IDOR filed liens with individual county recorders; now all tax liens are filed in the centralized online registry. Liens are enforceable for 20 years. Anyone can search the registry at tax.illinois.gov/programs/taxlienregistry.html. There are no additional filing or release fees through the registry itself, though taxpayers may still be responsible for certain lien-related fees depending on context.
