IRS Audit Risks for Retirees

Chad Dickinson • April 3, 2026
Retirement may mean the end of your working years—but it doesn’t mean you’re off the IRS radar.

While the IRS audits less than 1% of individual tax returns, certain financial situations can increase your chances of being flagged. For retirees, understanding these risks is key to avoiding unnecessary scrutiny, penalties, and stress.

Let’s break down the most common IRS audit triggers retirees should be aware of.

1. High Income from Investments or Retirement Accounts

Even if you’re no longer working, you may still have significant income.


Retirees often receive income from:


  • Investment portfolios (capital gains, dividends)
  • Retirement accounts (IRA or 401(k) distributions)
  • Rental properties or other passive income streams


The IRS tends to focus more on higher-income taxpayers. If your retirement income is substantial—especially approaching or exceeding $400,000—it increases the likelihood of closer review.

2. Failing to Report All Income

One of the most common audit triggers is mismatched income.


The IRS receives copies of your tax documents, including:


  • Forms 1099 (investment income, retirement distributions, interest)
  • Social Security benefit statements
  • Any W-2s from part-time work


If your tax return doesn’t match what the IRS has on file, it can quickly raise a red flag.


This is especially important for retirees who have multiple income sources. Even small omissions can trigger notices.

3. Required Minimum Distribution (RMD) Mistakes

This is a big one.


Once you reach age 73, the IRS requires you to take Required Minimum Distributions (RMDs) from certain retirement accounts.


Failing to take your RMD—or not taking enough—can result in a 25% penalty on the amount that should have been withdrawn.


This is one of the most avoidable (yet common) mistakes retirees make.

4. Gambling Income and Losses

If you gamble—whether casually or frequently—you are required to report:


  • All gambling winnings as income
  • Losses (but only up to the amount of winnings)



A common mistake is reporting losses without reporting winnings, which can immediately attract IRS attention.

5. Business or Side Income Errors

Many retirees stay active with:


  • Consulting work
  • Small businesses
  • Side gigs


If you’re earning income, the IRS expects accurate reporting.



Additionally, claiming business losses year after year can raise concerns. The IRS may determine your activity is a hobby, not a business—meaning your deductions could be disallowed.

6. Large Charitable Contributions

Charitable giving is great—but large or unusual deductions can trigger scrutiny.


This is especially true if:


  • Donations represent a large percentage of your income
  • You donate high-value non-cash items



Proper documentation is critical here. Without it, deductions can be denied.

7. Foreign Accounts and Income

The IRS has increased its focus on international compliance.


If you have:


  • Foreign bank accounts
  • Overseas investments
  • Income from outside the U.S.



You may be required to report this through additional filings.


Failure to do so can lead to penalties—and increase your audit risk.

How Retirees Can Reduce Audit Risk

The good news? Most audit risks are avoidable with proper planning.


Here are a few simple steps:


  • Report all income accurately
  • Ensure you take your RMDs on time
  • Keep good records and documentation
  • Double-check your return for errors or mismatches
  • Work with a professional if your situation is complex
