Why did the IRS send me a letter?

A letter or notice from the IRS doesn’t necessarily mean you're being audited. Some don't even require a response.

The IRS sends notices and letters for the following reasons:

  • You have a balance due.

  • You're getting a larger or smaller refund.

  • You need to verify your identity.

  • The IRS needs more info about your return.

  • The IRS changed your return.

  • Processing your return has been delayed.

Do I need to respond to an IRS letter?

Addressing your letter as soon as you receive it could prevent further IRS contact or examination.
