Top 10 Audit Red Flags the IRS Looks for in Self-Employed Returns

Here are the 10 IRS audit red flags most likely to trigger scrutiny for self-employed and Schedule C filers, drawn from the Kiplinger article  :

1. Excessive Deductions or Losses — Large write‑offs compared to income, or repeated Schedule C losses that offset other income.

2. High Income — Self-employed taxpayers with high gross receipts see higher audit risk.

3. Cash-Intensive Business — Businesses relying heavily on cash transactions draw scrutiny.

4. Unreported or Underreported Income — Missing 1099s or not reporting all known income is a red flag.

5. Disguising a Hobby as a Business — Years of losses with no profit motive may trigger hobby-loss rules.

6. Home Office Deduction — If it’s not exclusively used for business, the IRS may challenge it.

7. Large Charitable Donations — Giving more than typical for your income bracket draws attention.

8. Entertainment and Travel Expenses — These are often over-claimed or inadequately documented.

9. Rounded or Estimated Numbers — Whole-dollar entries look inauthentic to the IRS.

10. Math or Reporting Errors — Simple mistakes or mismatches with IRS data systems (AUR) can escalate.
