Explains purpose of the letter 4087C

We are sending you Letter 12C because we need more information from you to complete the processing of your individual income tax return.

We are requesting your assistance in locating a taxpayer that may or may not be currently employed by you.

This first notice is sent to tell the taxpayer they may be subject to backup withholding for unreported or unpaid interest or dividend income.

If you received an IRS CP01A Notice, the IRS is explaining how to use your Identity Protection Personal Identification Number (IP PIN).

You may qualify to receive the Child Tax Credit (CTC), or receive additional Child Tax Credit, for 2021, but you need to file a 2021 income tax return to claim the credit.

This is the fourth and final notice about your unresolved underreported or unpaid interest and dividend income. If you don’t resolve the issue by the date on your notice, we’ll send a final "C" notice and put backup withholding into effect.

We sent you this notice because when you filled out your tax return, you didn’t check the box that says someone else can claim you as a dependent. Our records show someone else claimed you as a dependent.
