Chicago IRS Tax Attorney: Illinois Tax Problems, IRS Audits, and Federal Tax Debt Resolution

Chicago taxpayers operate under a multi-layered tax system: federal income tax (IRS), Illinois state income tax (Illinois Department of Revenue), and the City of Chicago’s various local business and property taxes. When any of these layers goes wrong — whether through an IRS audit, unfiled returns, tax debt, or garnishment — the result is a compounding problem that requires strategic resolution.

Segal, Cohen & Landis, P.C. (SCL) represents Chicago clients before the IRS and in US Tax Court — handling tax audits, back tax resolution, wage garnishment releases, and international compliance. This guide covers Chicago’s key IRS exposure areas and what to do when the IRS contacts you.

Chicago’s Tax Environment

Chicago’s economy — driven by finance, professional services, manufacturing, healthcare, and real estate — creates specific IRS risk profiles:

  • Financial industry income: Traders, investment managers, and financial professionals in Chicago’s futures and equities markets generate complex income — Section 1256 contracts, partnership K-1 distributions, and carried interest — that carries elevated audit risk.
  • Real estate transactions: Chicago’s significant real estate market generates depreciation recapture, like-kind exchange timing issues, and passive activity loss disputes that the IRS frequently examines in field audits.
  • Small business and franchise operations: Chicago is a major hub for restaurant, hospitality, and franchise businesses. Cash-intensive business income and payroll tax issues are among the most common IRS triggers for Chicago small business owners.
  • Large immigrant community: Chicago’s Polish, Mexican, Filipino, Indian, and Korean communities include many taxpayers with foreign financial accounts and international tax reporting obligations that aren’t always on their radar.

Common IRS Issues for Chicago Taxpayers

IRS Audits in Chicago

Chicago is one of the largest IRS district offices in the country, with significant examination capacity for both individual and business returns. Common audit triggers for Chicago filers:

  • Self-employment income (Schedule C) with large deduction-to-income ratios
  • Real estate depreciation and rental losses inconsistent with passive activity rules
  • Business-use-of-vehicle deductions without proper mileage logs
  • Foreign account activity matched by FATCA data from foreign banks
  • Cryptocurrency trading gains underreported or misclassified
  • Payroll tax (Form 941) discrepancies between employment tax returns and employee W-2s

Payroll Tax Problems

Payroll tax issues are among the most serious IRS problems facing Chicago business owners. If your business falls behind on Form 941 employment tax deposits — even temporarily, due to cash flow — the IRS can assert Trust Fund Recovery Penalties (TFRP) personally against officers, owners, and “responsible persons” who had authority over the business’s finances.

The TFRP equals 100% of the unpaid trust fund taxes (the employee portion of Social Security, Medicare, and income tax withheld). It’s assessed personally, bypasses business bankruptcy protection, and cannot be discharged in bankruptcy. If your Chicago business is behind on payroll taxes, contact a tax attorney immediately.

IRS Tax Debt and Back Taxes

Chicago residents with years of unfiled tax returns or unpaid IRS balances face IRS collection actions that can move quickly from notice to levy. Illinois has its own state income tax (currently 4.95% flat rate) and the Illinois Department of Revenue will also pursue collection independently — meaning Illinois and IRS levies can hit simultaneously.

Resolution options for Chicago taxpayers with IRS tax debt:

  • Installment Agreement: Monthly payments up to 72 months. Streamlined IA (no financial review) available for balances under $50,000.
  • Offer in Compromise: Settle the IRS balance for less than the full amount. Chicago’s local living expense standards factor into the calculation of your available income and minimum offer amount.
  • Currently Not Collectible: If your income doesn’t exceed allowable expenses, the IRS will temporarily suspend collection. No payments while CNC status is active.
  • IRS Appeals: If you disagree with an IRS audit finding, you have appeal rights to the IRS Independent Office of Appeals and, ultimately, U.S. Tax Court.

What to Do When You Receive an IRS Notice in Chicago

Every IRS notice is time-sensitive. The specific deadline depends on the notice type — but common deadlines are 30 days, 60 days, or 90 days from the notice date. Missing a deadline can result in automatic tax assessment, loss of appeal rights, or loss of Tax Court petition rights.

When you receive an IRS notice:

  1. Identify the notice type (look for the notice number in the upper right corner — CP2000, Letter 1058, Notice of Deficiency, etc.)
  2. Note the response deadline in the notice text
  3. Contact a tax attorney before responding — your written response to the IRS becomes part of the permanent record
  4. Gather documentation for the specific items the IRS is questioning
  5. Do not contact the IRS directly without representation if there is potential fraud exposure or if the notice proposes a large assessment

Frequently Asked Questions — Chicago IRS Tax Attorney

Can you represent Chicago clients without them traveling to California?

Yes. IRS tax practice is entirely federal — there is no requirement that your attorney be in the same state as you. We handle all Chicago client communications, document exchange, and IRS representations remotely. No travel required.

My Chicago business has unfiled 941 payroll tax returns — how serious is this?

Very serious. Unfiled 941 returns trigger IRS Substitute For Return (SFR) assessments, and unpaid payroll taxes generate Trust Fund Recovery Penalty exposure for business owners and officers. The IRS prioritizes payroll tax collection over most other types of back taxes. Act quickly — the Trust Fund Recovery Penalty can be personally assessed against you within 3 years of the TFRP becoming collectible.

What is the Illinois IDOR — and does it interact with the IRS?

The Illinois Department of Revenue (IDOR) is Illinois’s state tax authority. The IRS and IDOR share information under federal-state tax data exchange agreements. If the IRS adjusts your federal return, the IDOR receives notification and can open its own examination. Similarly, if you file amended federal returns, you should file amended Illinois returns as well. A complete resolution strategy addresses both federal and Illinois state tax simultaneously.
