Your IRS notice or letter will explain the reason for the contact and give you instructions on how to handle the issue.

If you agree with the information, there is no need to contact us.

Enter your notice or letter number above to get more information on IRS notices and letters, along with answers to many notice-related questions. If your notice or letter doesn’t return a result using the Notices & Letters Search on this page, contact us at the toll-free number 800-829-1040.

Why Was I Notified By The IRS?

The IRS sends notices and letters for the following reasons:

• You have a balance due.
• You are due a larger or smaller refund.
• We have a question about your tax return.
• We need to verify your identity.
• We need additional information.
• We changed your return.
• We need to notify you of delays in processing your return.

Next Steps

Read

Each notice or letter contains a lot of valuable information, so it’s very important that you read it carefully. If we changed your tax return, compare the information we provided in the notice or letter with the information in your original return.

Respond

If your notice or letter requires a response by a specific date, there are two main reasons you’ll want to comply:

• to minimize additional interest and penalty charges.
• to preserve your appeal rights if you don’t agree.

Pay

Pay as much as you can, even if you can’t pay the full amount you owe. You can pay online or apply for an Online Payment Agreement or Offer in Compromise. Visit our payments page for more information.

Keep A Copy Of Your Notice Or Letter

It’s important to keep a copy of all notices or letters with your tax records. You may need these documents at a later date.

Contact Us

We provide our contact phone number on the top right-hand corner of the notice or letter. Typically, you only need to contact us if you don’t agree with the information, if we requested additional information, or if you have a balance due. You can also write to us at the address in the notice or letter. If you write, allow at least 30 days for our response.

The Location Of The Notice Or Letter Number

You can find the notice (CP) or letter (LTR) number on either the top or the bottom right-hand corner of your correspondence.
