- If you’re being audited by the Illinois Department of Revenue (IDOR), you have legal rights and options. You should not face the exam process alone.
- Field audits often focus on sales and use tax, and may expand into multi-year assessments, penalties, or even personal liability.
- The Law Offices of Michael Raff provides strategic, experienced audit defense representation to protect you and your business from excessive tax assessments and ensure full compliance.
It often starts with a letter. Maybe it has the Illinois Department of Revenue logo in the corner. Or perhaps someone shows up at your place of business unannounced, flashing a badge and asking about records. However it begins, a civil tax examination by the IDOR is not something to take lightly.
For many small businesses in Illinois, a field audit feels like a financial ambush. What was routine can turn into a full-blown dispute involving years of records, missing receipts, and penalties that far exceed the original tax liability. But you don’t have to go through it alone. At The Law Offices of Michael Raff, we help clients protect their rights and finances during tax examinations and audits through strategic planning, informed defense, and skilled negotiation.
What Is an IDOR Field Examination?
A field examination (or audit) is an in-depth review conducted by the Illinois Department of Revenue. These are commonly triggered by:
- Suspected underreporting of sales or income
- Missing or inconsistent filings
- Random selection
- Tips, complaints, or discrepancies between federal and state records
Unlike routine tax correspondence, a field exam involves close scrutiny. The auditor may want to examine:
- Business bank accounts
- Sales tax returns and receipts
- POS systems and sales reports
- Federal tax filings and payroll information
- Vendor invoices and deductions
These exams often go back three years, and if errors are found, the state may initiate what’s known as a “second cycle audit”, another multi-year review that can substantially increase exposure and penalties.
What Happens During an Illinois Audit?
Audits by IDOR are methodical and time-consuming. The process typically involves:
- Initial Contact: A phone call or notice letter introduces the audit scope.
- Document Requests: Auditors request bank records, general ledgers, purchase records, etc.
- Interviews: They may ask detailed questions about your business operations.
- Assessment: The state will review all documents that you provide and that they independently obtain, looking for discrepancies or noncompliance.
- Final Determination: If deficiencies are found, you’ll receive a Notice of Tax Liability which outlines the proposed tax, interest, and penalties.
Throughout the process, your answers and what you choose to share can shape the outcome. That’s why legal representation from a qualified exam representation tax lawyer is essential from day one.
Your Rights During a Tax Examination
You have rights during a Department of Revenue audit, including:
- The right to representation by a qualified tax attorney
- The right to understand the scope and timeline of the audit
- The right to appeal a proposed determination
- The right to privacy and protection of confidential business data
Unfortunately, many taxpayers unknowingly waive these rights by speaking freely to examiners or handing over documentation without legal advice. Our office ensures you make informed decisions every step of the way.
Why You Need a Tax Lawyer During an IDOR Examination
At first glance, the process may seem administrative. But what starts as an audit often evolves into a legal dispute. If the Department finds material issues, they may pursue:
- High-dollar assessments
- 20%–50% penalties on underreported taxes
- Revocation of a sales tax permit
- Personal liability for unpaid business taxes
- Referral to the Attorney General for criminal investigation
By having skilled exam representation attorneys at the Law Offices of Michael Raff by your side, you protect your legal rights and position yourself for a fair outcome. Our firm helps with:
- Communicating with examiners and limiting overreach
- Controlling what is (and isn’t) provided
- Identifying weaknesses in IDOR’s position
- Asserting valid deductions, exemptions, and defenses
- Pursuing settlement, abatement, or further appeal if needed
Strategic Audit Defense for Illinois Businesses
We don’t just react. We prepare. Before you ever meet with the Department, we conduct a thorough internal compliance review, examining:
- Whether your records align with IDOR expectations
- If your sales tax reporting was consistent
- What exposure exists and how to minimize risk
- How to prepare your financial documentation
- Whether your filing practices complied with state tax regulations
This gives us a roadmap for defense and negotiation, not guesswork.
Common Audit Triggers and Issues We See
Every case is unique, but some common themes in Illinois audits include:
- Underreported sales or “off-book” cash transactions
- Failure to remit use tax on out-of-state purchases
- Misuse of exemption certificates
- Poor or incomplete recordkeeping
- Unfiled or missing returns
These issues often come down to interpretation and evidence. We help build a strong case to challenge assumptions and fight back.
What to Do If You’ve Received an Audit Notice
If you’ve been contacted by the Illinois Department of Revenue, don’t panic, but don’t wait either.
Here’s what to do:
- Don’t speak with the examiner until you talk to a lawyer.
- Gather any notices or letters you’ve received.
- Contact a qualified exam representation attorney for a confidential consultation.

Frequently Asked Questions
What if I’ve already spoken to the IDOR agent?
That’s okay, but don’t do so again without legal advice. We can step in immediately to manage the process and limit further risk.
Can I appeal an audit result?
Yes. If you disagree with the proposed liability, we can help you appeal the findings through administrative hearings, the Informal Conference Board or the Independent Tax Tribunal depending on the case.
Can I negotiate the amount I owe?
Often, yes. If the liability is based on estimates or assumptions, we may be able to reduce it at exam or through available appeal options. We can also seek penalty abatement where appropriate.
What if my records were lost in a disaster?
We’ve helped many clients rebuild lost documentation and present alternative evidence. Let us assist you in proving your case.
Will an audit always result in money owed?
Not necessarily. With skilled audit defense, we may be able to show no deficiency or in certain (rare) cases help a taxpayer obtain a refund.
