Identity and Tax Return Verification Service

The IRS proactively identifies and stops the processing of potential identity theft returns. You may receive a notice or letter asking you to verify your identity and tax return information with the IRS. This helps prevent an identity thief from getting your refund.

You may receive letters 4883C or 6330C from the IRS.

What this letter is about

IRS received a federal income tax return, Form 1040-series, filed under your Social Security number (SSN) or individual tax identification number (ITIN). They need you to verify your identity and your tax return, so that they can continue processing it.

What you need to do immediately

Call the Taxpayer Protection Program Hotline shown in your 4883C or 6330C letter.

Have ALL of the following available when you call:

• The 4883C or 6330C letter;
• The Form 1040-series tax return referenced in the letter (Forms W-2 and 1099 aren’t tax returns)
• A prior year tax return, other than the year in the letter, if you filed one (Forms W-2 and 1099 aren’t tax returns)
• Supporting documents for each year’s tax return you filed (e.g., Form W-2, Form 1099, Schedules C, Schedule F, etc.)

Taxpayers who have received either a 5071C notice or a 5447C or 5747C letter can verify their identity online through the IRS website. The letter should include the IRS website address.

If you DIDN’T file a tax return: Someone may have filed a fraudulent tax return using your name and SSN or ITIN. If you didn’t file a tax return for the tax year shown on your letter, let IRS know immediately as you may be a victim of identity theft.
