What is a CP3219A notice?

Understanding your CP3219A notice

The IRS received information that is different than your tax return. The change may result in a decrease or increase in tax. The notice explains how the tax amount was calculated. If you disagree, you can challenge this in U.S. Tax Court.

H2 Why you received the CP3219A notice

You received a CP3219a notice because the IRS has information that differs from what you reported on your tax return. That information has led the IRS to change the amount of income tax on your return. You have received one or more notices from the IRS asking for verification of income, credits or deductions on your return, and you did not respond.

Likely next steps

As always, read the notice carefully. Your notice will outline the increase or decrease in your tax based on the information the IRS received from a third party, like your bank or employer, after you filed your return.. 

If you agree with the IRS assessment, you will need to sign the enclosed Form 5564, Notice of Deficiency - Waiver, and mail to the address shown on the CP3219a notice and the IRS will then send you a bill for the amount owed.

If you disagree with the IRS assessment, according to the IRS, “…you have the right to challenge the proposed changes by filing a petition with the U.S. Tax Court no later than the date shown on the notice.”
