How to Find a Certified Public Accountant (CPA) for IRS Audit Help in Chicago

You just opened your mail. There it is—that envelope from the IRS. Your hands might be shaking a little. I’ve seen that look on hundreds of faces over the years, right here in Chicago, and I can tell you something that might help: you’re not alone, and you absolutely don’t have to handle this by yourself.

The moment you realize the IRS wants to audit your return, your next move matters more than you think. Who you hire to represent you can mean the difference between a quick resolution with minimal changes and a drawn-out nightmare that costs you thousands more than it should have. Finding the right CPA for IRS audit help in Chicago isn’t just about opening Google and picking the first name that pops up.

I’ve spent over 15 years helping taxpayers navigate IRS audits, and I’ve watched people make some costly mistakes when choosing representation. Some hired their cousin’s friend who “does taxes.” Others went with the cheapest option they could find. A few tried to go it alone because they thought hiring help meant admitting guilt. None of those approaches worked out well.

What you need is someone who knows the IRS inside and out, understands Illinois tax nuances, and can speak the language of auditors without breaking a sweat. That person is usually a qualified CPA—but not just any CPA.

Why You Need a CPA (Not Just Any Tax Preparer) for an IRS Audit

Here’s something most people don’t realize until it’s too late: the person who prepared your tax return might not be legally allowed to represent you during an audit.

That tax preparer at the strip mall? If they don’t have specific credentials, they can’t go with you to an IRS meeting. They can’t negotiate on your behalf. They can’t even make phone calls to the IRS about your case. The IRS only allows certain professionals to represent taxpayers: CPAs, Enrolled Agents (EAs), and tax attorneys.

When I started in this field back in 2009, I watched a small business owner in Naperville try to handle a sales tax audit herself because her regular bookkeeper couldn’t represent her. She had no idea what documentation the auditor actually needed. She over-shared information that wasn’t requested. She got flustered and contradicted herself. What should have been a $3,000 adjustment turned into a $12,000 bill plus penalties.

A CPA brings something crucial to an audit: representation rights and technical expertise that goes way beyond basic tax preparation.

CPAs undergo rigorous education requirements—typically 150 semester hours of college coursework, which is more than a standard bachelor’s degree. They pass one of the hardest professional exams in the country (the Uniform CPA Exam), and they’re required to complete continuing education every year. In Illinois, that means 120 hours every three years, with specific ethics requirements, according to the Illinois Department of Financial and Professional Regulation.

But here’s what really matters during an audit: CPAs understand the tax code deeply. They know what the IRS is actually looking for. They can spot issues before they become problems and know which battles are worth fighting.

Tax attorneys are great for complex legal situations or when you’re potentially facing criminal charges. Enrolled Agents specialize specifically in taxes and are also excellent for audit representation. But for most individual and small business audits in Chicago, a good CPA with audit defense experience hits the sweet spot—they understand the technical tax issues, they know the local business environment, and their fees are usually more reasonable than attorneys.

In my experience, CPAs who regularly handle IRS audits develop relationships with local IRS offices. They know the procedures. They know how Chicago-area auditors typically work. That local knowledge is worth more than you might think.

What Credentials and Qualifications to Look for in a Chicago CPA

Not all CPAs are created equal when it comes to audit representation. I’ll be blunt: your neighbor who’s a CPA at a manufacturing company probably isn’t the best choice for your audit, even if they offer to help for free.

You need someone who actually practices in tax and has specific audit experience.

Active Illinois CPA License

First thing: verify they’re actually licensed. Sounds obvious, but you’d be surprised. Illinois requires CPAs to maintain an active license, and you can verify this yourself through the IDFPR’s online verification system. Takes about 30 seconds. Do it.

Tax Specialization, Not Just General Accounting

Many CPAs work in corporate accounting, auditing (the non-IRS kind), or consulting. They might be brilliant at financial statements but haven’t dealt with an IRS auditor in years—or ever. You want someone who lists tax services and audit representation as their primary practice areas.

IRS Representation Experience

Ask directly: “How many IRS audits have you handled in the past year?” If they hesitate or give you a vague answer, keep looking. Someone who regularly represents taxpayers in audits should be able to give you a ballpark number without blinking.

When I worked on a particularly messy correspondence audit for a freelance designer in Wicker Park back in 2021, the difference between her previous preparer and our approach was night and day. Her preparer had done her return but had never actually responded to an IRS audit notice before. Every response took weeks because they were essentially learning on her dime.

Additional Credentials Worth Noting

Some CPAs hold additional certifications that signal deeper expertise:

• Personal Financial Specialist (PFS) designation from the American Institute of CPAs shows expertise in financial planning
• Certified Tax Strategist or similar credentials
• Former IRS agent or revenue officer experience (seriously, this is gold—they know exactly how the other side thinks)

Professional Memberships

Membership in professional organizations matters. CPAs who belong to the AICPA or the Illinois CPA Society typically stay current with tax law changes and have access to better resources. These aren’t just resume decorations—they indicate someone who takes their professional development seriously.

Where and How to Find a Qualified CPA for IRS Audit Help in Chicago

So you’re convinced you need a CPA. Now what? Where do you actually find this person?

Start with Professional Directories

The AICPA maintains a “Find a CPA” directory that lets you search by location and specialty. You can filter specifically for tax services in Chicago. The Illinois CPA Society has a similar tool.

These directories won’t tell you if someone is actually good, but they do confirm credentials and give you a vetted starting point.

Referrals from People Who’ve Actually Been Through an Audit

This is probably the most valuable source, but it requires some vulnerability. If you know anyone—friend, business colleague, family member—who’s been through an IRS audit, ask who represented them and what their experience was like.

Business owner networks in Chicago, like local chambers of commerce or industry associations, can be goldmine for referrals. People who run businesses tend to have experienced tax issues and know who the competent CPAs are.

Local Tax Resolution Firms vs. Solo Practitioners

You’ll find both options in Chicago. Larger tax resolution firms might have more resources and specialists for different tax issues. Solo practitioners or small firms often provide more personalized attention.

Neither is automatically better. I’ve seen excellent work from both. What matters is the specific CPA who’ll be handling your case, not the size of their firm.

Avoid the TV Advertisement Firms (Usually)

You know the ones. The national companies with those late-night commercials promising to “settle your tax debt for pennies on the dollar!” Many of these are essentially marketing machines that farm out the actual work. You might pay premium prices but get a junior associate who just passed their EA exam last month.

Not all advertised firms are bad, but be extra careful. Check reviews, verify the credentials of the actual person who’ll work on your case, and watch for high-pressure sales tactics.

Geographic Considerations in Chicago

Chicago’s a big city. Do you need someone in your specific neighborhood? Not necessarily, especially since much audit work happens via mail, phone, and secure document portals now.

That said, if you have an in-person audit (less common post-2020, but they still happen), having a CPA familiar with the Chicago IRS office locations can be helpful. The IRS has offices in the Loop and in the suburbs. A local CPA will know the parking situation, office procedures, and may even be familiar with specific auditors.

For many Chicagoans, finding someone in the broader metro area works fine as long as they’re responsive and communicate well.

Online Research and Reviews

Google reviews, Yelp, Better Business Bureau—yes, check these, but with a critical eye. Tax situations are confidential, so legitimate CPAs won’t have hundreds of detailed public reviews like restaurants do.

Look for patterns. If multiple reviews mention poor communication or surprise fees, that’s a red flag. One or two negative reviews among many positive ones? That’s normal. Every professional occasionally deals with an unhappy client.

What About Those “Free Consultation” Offers?

Many CPAs offer a free initial consultation for audit cases. This is legitimate and actually helpful—it gives both of you a chance to see if it’s a good fit.

Use this time to ask questions (more on that next), get a feel for their communication style, and understand their fee structure. If they’re pushy or make guarantees about your audit outcome, walk away. No one can guarantee what the IRS will do.

Questions to Ask Before Hiring a CPA for Your Audit

You’ve found a few potential CPAs. You’ve got consultations scheduled. Now you need to know what to actually ask.

I tell people to approach this like a job interview—because that’s what it is. You’re hiring someone for an important job. They should be able to answer these questions clearly and confidently.

“How many IRS audits have you personally handled?”

Notice the word “personally.” You’re not hiring the firm’s 30 years of combined experience. You’re hiring this individual CPA.

If they’ve handled dozens or hundreds of audits, great. If your case would be their first or second? Maybe not ideal unless they’re being supervised by someone more experienced.

“What types of audits do you have the most experience with?”

IRS audits come in different flavors:

• Correspondence audits (handled entirely by mail)
• Office audits (you or your representative meets with an auditor at an IRS office)
• Field audits (an IRS agent comes to your business or home)
• Specific issue audits (like the Earned Income Tax Credit or home office deduction)

The CPA should have experience with your specific type of audit. A field audit of a construction company is a very different animal from a correspondence audit about charitable deductions.

“What’s your approach to dealing with IRS auditors?”

This reveals a lot about their style. Some CPAs are more aggressive and confrontational. Others prefer a cooperative, diplomatic approach.

Neither is wrong, but it should match your situation and temperament. For most routine audits, cooperative professionalism works best. For cases involving serious disputes or potential fraud allegations, you might want someone more aggressive—or even a tax attorney.

“Will you personally handle my case, or will it be assigned to someone else?”

At larger firms, partners might do the sales pitch, but associates handle the actual work. That’s not necessarily bad if the associate is competent and supervised, but you should know upfront who’ll be doing what.

I get annoyed when I hear about CPAs who promise personal attention and then delegate everything to staff without telling the client. That’s not how professionals should operate.

“What documentation will I need to gather?”

A good CPA should be able to tell you—at least generally—what records you’ll need based on what the IRS is auditing. This also tests their knowledge. If they can’t explain what documentation typically matters for your specific audit issue, that’s concerning.

“What are realistic outcomes for my situation?”

Watch out for anyone who guarantees they’ll get the audit dismissed or promises “no additional tax owed.” They cannot know that.

What you want to hear is something like: “Based on what you’ve told me, if you have the documentation to support these deductions, we should be able to defend most of them. If we’re missing some records, we might need to negotiate or concede certain items.”

“How do you charge, and what’s your estimate for my case?”

This is critical and gets its own section below.

“What’s your typical timeline for responding to the IRS?”

The IRS gives deadlines—usually 30 days to respond to correspondence audit letters. Your CPA should work well within those deadlines. If they say they’re usually too busy to respond within the IRS timeframe, run. Extensions are possible but shouldn’t be the default approach.

Understanding Costs and Fee Structures for Audit Representation

Money. It’s awkward to talk about, but you need to know what you’re getting into.

The most common mistake I see people make is choosing a CPA based purely on price. The cheapest option often costs more in the end when the audit drags on or gets mishandled.

Typical Fee Structures

Most CPAs use one of these billing approaches for IRS audit representation:

Hourly Rates

This is common in Chicago. Expect anywhere from $200 to $500+ per hour depending on the CPA’s experience, firm size, and case complexity.

For a simple correspondence audit with good documentation, you might be looking at 3-8 hours of work total. More complex cases can run 20+ hours.

Hourly billing is fair if the CPA is efficient and keeps you informed about time spent. Ask for written time records.

Flat Fees

Some CPAs offer flat fee arrangements for straightforward audits—maybe 1,500−1,500−3,500 for a basic correspondence audit.

This gives you predictability. Just make sure you understand exactly what’s included and what triggers additional charges.

Retainer Arrangements

For more complex audits or if your case might escalate, a CPA might ask for a retainer upfront (say, $5,000) and bill against it hourly, replenishing as needed.

What Should Be Included in the Fee?

Clarify what you’re paying for:

• Initial case review and strategy planning?
• Gathering and organizing your documentation?
• Drafting written responses to the IRS?
• Phone calls or meetings with IRS auditors?
• In-person representation if needed?
• Appeals if you disagree with the audit results?

Also ask about costs for things like:

• Photocopying and document production
• Professional research
• Travel time to IRS offices

These can add up if you’re not expecting them.

Red Flags in Fee Discussions

Be very cautious if a CPA:

• Won’t give you a written fee agreement
• Charges based on the amount they “save” you (this violates professional ethics for CPAs)
• Requires large upfront payments with no clear explanation
• Is vague about what their fees cover

Is It Worth the Cost?

I had a client in Lincoln Park who balked at paying $2,800 for audit representation on a dispute over about $5,000 in deductions. She decided to handle it herself to save money.

She eventually hired us anyway—after she’d already made some admissions to the auditor that hurt her case and after the stress gave her three weeks of terrible sleep. We still got a decent outcome, but it would have been easier and less expensive (in terms of additional tax owed) if she’d hired help from the start.

When the IRS is questioning $10,000 in deductions (which could mean 2,500−2,500−4,000 in additional tax plus penalties), paying a few thousand for competent representation is often worth it. Plus, you get peace of mind and avoid making mistakes that could trigger additional scrutiny.

For very small audits—like the IRS questioning a $500 deduction—you might reasonably handle it yourself if you have clear documentation. But most audits involve enough money and complexity that professional help pays for itself.

Payment Plans

Many Chicago CPAs understand that getting an IRS audit notice often comes at a financially stressful time. Ask if they offer payment arrangements. Some will let you pay in installments if you’re upfront about your situation.

Ultimately, when you find a CPA for IRS audit help, you’re not just buying technical knowledge. You’re buying experience, advocacy, and someone to stand between you and the IRS machinery.

I’ve seen the relief on clients’ faces when they realize they don’t have to figure this out alone. That a professional who’s been through hundreds of these situations has their back. That relief is hard to put a price on.

Finding the best CPA for IRS audit in Chicago takes some effort—verifying credentials, asking the right questions, understanding costs. But spending a few hours on that research can make the difference between a stressful disaster and a manageable process.

Chicago has plenty of qualified CPAs who do this work well. You just need to know how to find them and what to look for. Start with the professional directories, get referrals if you can, verify their licenses through IDFPR, and don’t be shy about asking questions during consultations.

And remember: the IRS audit notice came with a deadline. Don’t procrastinate on finding help. The earlier in the process you get a qualified CPA involved, the better your options and the stronger your position.

You’re going to get through this. With the right CPA on your side, you’ll be in much better shape than trying to go it alone.

Frequently Asked Questions

How much does a CPA cost for an IRS audit in Chicago?

Most Chicago CPAs charge between 200−200−500 per hour for audit representation, or flat fees ranging from $1,500 to $5,000+ depending on complexity. A simple correspondence audit might cost 2,000−2,000−3,500 total, while complex field audits of business returns can run significantly higher. Always get a written fee agreement upfront that explains the billing structure and what services are included.

Can a CPA represent me in all types of IRS audits?

Yes. CPAs with active licenses have unlimited representation rights before the IRS, meaning they can represent you in any type of audit—correspondence, office, or field audits. They can also represent you in appeals and collections matters. This is one of the major advantages of hiring a CPA over a non-credentialed tax preparer who has very limited representation rights.

What’s the difference between a CPA and an Enrolled Agent for audit help?

Both CPAs and Enrolled Agents (EAs) can fully represent you before the IRS. CPAs have broader accounting education and often work in other areas beyond tax. EAs specialize specifically in taxation and IRS representation. For most audits, either can be excellent—what matters more is their specific experience with cases like yours. EAs are licensed federally by the IRS rather than by state boards like CPAs.

How quickly should I hire a CPA after receiving an audit notice?

As soon as possible. IRS audit notices typically give you 30 days to respond. You want a CPA involved early so they can review your situation, gather proper documentation, and craft an appropriate response strategy. Waiting until a few days before the deadline limits your options. If you’ve already missed a deadline, hire someone immediately—CPAs can often request extensions or reopen communication with the IRS, but the sooner they’re involved, the better.

Can I switch CPAs in the middle of an audit if I’m not satisfied?

Yes, you can change representation at any point, though it may cause some delays in your case. You’ll need to file a new Form 2848 (Power of Attorney) with the IRS designating your new representative. If you’ve already paid the first CPA, you likely won’t get that money back unless there was misconduct. If you’re thinking about switching, talk to your current CPA about your concerns first—sometimes communication issues can be resolved more easily than you think.
