IRS Audit Red Flags Every Taxpayer Should Know

Filing taxes might not be the most thrilling task on your to-do list, but it’s one you definitely want to get done right. The last thing anyone wants is a dreaded letter from the IRS announcing an audit.

Did you know that some actions or discrepancies in your tax filings can significantly increase the odds of that happening? Yup, those pesky red flags can make you a target.

But here’s the good news: staying informed and proactive can help you steer clear of costly mistakes.

In this blog, we’ll explore the most common IRS audit red flags and dive into some industry-specific triggers for real estate professionals. By the end, you’ll know exactly what to watch out for when filing your taxes. Let’s jump in!

Common IRS Red Flags

The IRS isn’t randomly rolling dice to decide who to audit. They’re spotting patterns and looking for anything that seems out of place. Here are some of the most common red flags to keep in mind:

1. Unreported or Underreported Income

One of the biggest audit triggers is failing to report all your income. The IRS receives copies of all your income forms, like W-2s, 1099s, and more. If the numbers you report don’t match what they have, it’s an immediate red flag. This includes freelance work, side gigs, or any “under-the-table” earnings.

2. High Charitable Donations Relative to Income

While charitable donations are a great way to give back and save on taxes, claiming unusually high amounts compared to your income can make the IRS raise an eyebrow. They have statistical averages for how much people typically donate, and if your deductions seem out of the ordinary, they might take a closer look.

3. Excessive Business Expenses

For small business owners and self-employed individuals, claiming high business expenses is common—but there’s a limit. The IRS tends to scrutinize claims that seem excessive or out of proportion with your income, or not common for your type of business or industry. This could include things like extravagant travel, entertainment, equipment, or vehicle purchases. Keep those receipts and make sure every deduction is legitimate.

4. Excessive Home Office Deductions

Claiming a home office deduction is totally legitimate, but the IRS is quick to pounce if it seems like you’re stretching the truth. To qualify, your home office must be used exclusively for business. Overestimating the size of your office or claiming expenses for personal spaces in your home could land you in hot water.

5. Inconsistencies in Reporting

Inconsistent or mismatched numbers across your tax forms is a surefire way to catch the IRS’s attention. For example, if your 1099 income doesn’t align with what you report on your return, expect some questions. Double-check everything before you file—it’s worth the extra time.

Industry-Specific Red Flags for Real Estate Professionals

If you work in real estate, your tax situation is probably more complex than the average filer. Unfortunately, that also means you’re more likely to run into red flags. Here are some triggers specific to real estate professionals:

1. Reporting Large Property Sales Without Documentation

Whenever you sell a property, the IRS expects detailed documentation, like settlement statements, sales contracts, and proof of expenses. Reporting large property sales without proper records is like waving a red flag in front of a bull—it’s bound to attract attention.

2. Overstating Deductions for Rental Properties

Rental properties come with plenty of potential tax deductions, but there’s a fine line between claiming legitimate expenses and overstating them. Whether it’s repairs, depreciation, or operating costs, make sure your deductions are backed up by accurate records.
Additionally, reporting your properties in one box on Schedule E could trigger an audit as expenses may appear overstated. To avoid this, make sure to report each property separately on Schedule E — good bookkeeping can help with this.

3. Not Properly Categorizing Income

Income from real estate can come in many forms—commissions, rental payments, or even profits from flipping houses. Misclassifying this income or failing to report it properly can trigger an audit. Always categorize income correctly to avoid unnecessary scrutiny.
Another common mistake is misclassifying capital improvements and large renovations as repair and maintenance expenses rather than depreciating them—or worse, double-dipping. Another problem solved with good bookkeeping.

4. Failing to Report Passive Activity Losses Correctly

The rules for passive activity losses, like those from rental properties, are complex. Many taxpayers accidentally misreport losses, including erroneously electing the Real Estate Professional Status (REPS), leading to potential audits. If you’re unsure how to handle passive income or losses, it’s worth consulting a professional to avoid errors.

Tips to Avoid an IRS Audit

Preventing an audit is all about accuracy, honesty, and attention to detail. Here’s how you can protect yourself:

• Keep thorough records: Save receipts, invoices, and bank statements. The more organized your records, the better.
• Be realistic with deductions: Don’t exaggerate or overstate deductions, especially for things like home offices or business expenses.
• Double-check everything: Errors in math or mismatched numbers can trigger audits, so review your return carefully before filing.
• File electronically: E-filing reduces the chances of errors and speeds up the process.
• Get professional help: A CPA or tax specialist can ensure your filings are accurate and compliant with IRS rules.
