Common Tax Filing Mistakes That Trigger IRS Notices

02/19/2026

Most IRS notices don’t come from fraud—they come from avoidable filing errors. Every year, taxpayers in Rockwall, Rowlett, and Heath receive letters from the IRS for mismatched forms, incorrect calculations, or missing information. These mistakes can delay refunds, trigger audits, or result in penalties.

At Brozewicz CPA, we help individuals file accurate, compliant tax returns the first time. Here are the most common mistakes that trigger IRS attention—and how we help you avoid them. Find this great information.

1. Incorrect or Missing Social Security Numbers

A simple typo in your SSN or dependent’s number can lead to a rejected return or lost credits. We double-check all identifying information to prevent delays.

2. Mismatched Income Reporting

If you received a W-2 or 1099 and didn’t report it, the IRS will flag it. This includes:

  • Freelance or gig income reported on 1099-NEC
  • Investment income (1099-DIV or 1099-INT)
  • Retirement distributions (1099-R)

We reconcile all documents and cross-check with IRS records before filing.

3. Math Errors and Wrong Credits

Math errors may lead to underpayment penalties or missed refunds. Incorrectly claiming credits—like the Earned Income Tax Credit or Child Tax Credit—can raise red flags. A CPA ensures eligibility and accuracy.

4. Filing the Wrong Status

Claiming Head of Household without meeting IRS requirements is a top audit trigger. We guide you through status choices based on your exact living and income situation. Get tips about this filing blunder.

5. Overreporting or Misreporting Deductions

Inflated deductions—especially charitable donations, mileage, or business expenses—can get attention. We provide supportable documentation and IRS-compliant standards to protect your return.
