We can help you with your letter or notice from the IRS.

Addressing your letter or notice as soon as you receive it could prevent further IRS contact or examination. Look in your IRS letter or notice, and select the corresponding number in this article (like CP11 or CP01A) for more information about what to do next.

What should I do if I receive a letter from a state tax agency?

It’s best to contact your state directly to learn more about the letter you received. Select yours below for Department of Revenue contact information.

What should I do if I have an audit letter from tax year 2019 or earlier?

Go here for guidance on how to respond.

What types of audit protection does TurboTax provide?

TurboTax offers the following options for audit protection when you receive an audit notice.

    • Description:

      • Full audit representation by a licensed tax professional, as long as the tax return can be audited by the IRS or State, when you file an individual return with any TurboTax Online version through MAX.

      • TurboTax Expert Assist Business also includes lifetime audit protection.

    • Description:

      • Audit representation by a licensed tax professional, including representation in front of the IRS.

      • If you purchase Audit Defense on or before April 15, your coverage expires the following April 15. If you purchase after April 15 (through October 15), your coverage expires the following October 15.

      • Available in TurboTax Online through PLUS and TurboTax Advantage, or as a standalone service in TurboTax Desktop.

You can also contact TaxAudit at 877-829-9695.

How do I know if I purchased audit protection?

To determine if you purchased audit protection, sign in to your TurboTax account, select the tax year under Your tax returns & documents, and select View order details. If you have PLUS, Max Benefits, or Premium Services listed, then you purchased audit protection. In TurboTax Desktop, it’s called Audit Defense for TurboTax Desktop.

Tip: Have your notice and your tax return handy when you call.

Where can I find more helpful IRS information?

The IRS has some resources to search for and understand your notice, along with information to set up a payment plan. We’ve drafted a sample response letter you can use for reference.
