Frequently asked questions

Why is my return being reviewed?
We select some returns to determine if income, expenses, and credits are being reported accurately. This doesn’t mean you made an error or were dishonest. Please allow us 60 days to complete our review before contacting us.

What if I didn’t file the tax return?
Someone else may have filed it for you without your consent. Send us a completed and signed Form 14039, Identity Theft Affidavit (PDF). You may want to read our identity theft resource page for more information.
