๐ The overall IRS audit rate is just 0.4%. But that number hides a lot.
Certain patterns on your return raise your odds dramatically. Millionaires get audited at 10x the average rate. EITC claimants at nearly double.
The most common trigger is not fraud. It is a mismatch. The IRS receives copies of every W-2, 1099, 1099-R, and 1099-B filed in your name. When the income on your return does not match what they already have, their system flags it automatically.
For retirees, two of the biggest risks are missed RMDs and incorrect cost basis on investment sales. The IRS knows your account balances from custodian reporting. A skipped required distribution is one of the easiest flags for their computers to catch.
The round numbers issue trips up more people than you would expect. IRS auditors have said they can tell immediately when a taxpayer estimated their expenses instead of using actual records.
New for 2026: gambling losses are now capped at 90% of reported winnings, down from 100%. That change alone will generate mismatches for anyone still deducting losses the old way.
None of this means you should be afraid to claim legitimate deductions. It means your records need to match what the IRS already has.
