The IRS received your individual income tax return but more information is needed to process the return accurately.
A reply is needed within 20 days from the date of this letter. If the IRS doesn’t receive a response from you, an adjustment will be made on your account that may increase the tax liability that you will owe or reduce the amount of your refund.
You submitted your income tax return that was not able to be processed. A letter is being sent to you because more information is needed to complete the processing of your individual income tax return. This information can include:
The first thing to do is to check the return address to be sure it’s from the Internal Revenue Service and not from another agency, and not some type of a scam to obtain personal information from you.
Read the letter carefully and respond timely. If you need additional information, contact the IRS at the toll-free number listed on the top right corner of the letter.
Respond to the letter, even if you disagree with the information in the letter. If you disagree, send the IRS a letter explaining what information you think is in error. Provide the information requested in the letter.
Enclose only the information requested and any forms, schedules or other information required to support your entries and a copy of this letter. Don’t send a copy of your return unless the IRS asks you to do so. Do not file a Form 1040-X, Amended U.S. Individual Income Tax Return. After the IRS receives the requested information, they’ll use it to process your original tax return.
If you’re entitled to a refund, the IRS will send it about six to eight weeks from the time they receive your response.
If the adjustment to your account results in a balance due, pay the amount you owe by the due date on the letter. If you are not able to pay the full amount by the due date, pay as much as you can to limit penalties and interest. Visit Paying Your Taxes to consider online payment options. If you need additional assistance, call the IRS at the toll-free number on the top right corner of your letter.
