Notices Return Errors Notice CP10

The cp10 is a notice the IRS uses to suggest an adjustment to your tax return. They do this based on a piece of contrary information they got from third parties like employers, lenders, or banks. This information led them to believe that you owe additional taxes.

The IRS uses the Notice CP10 to rebuff an estimated tax payment into the next year.

While they use the notice CP10A to adjust a taxpayer’s Earned Income Credit.

The notice cp10 lists some items as missing on your return.  It is necessary for you to review this notice and confirm that those items are actually missing as stated.


Even though the cp10 proposes that your return be adjusted due to the documents supplied by third parties indicating some missing items, the cp10 can be wrong and you need to verify that.
