Frequently asked questions

Why is my return being reviewed?

We need to verify the income or the income tax withholding you reported on your return. This doesn’t mean you made an error or were dishonest.

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 resources page while we review your Form 14039.
