I got Notice CP09 or CP27 from the IRS. What is it?
Notice CP09 or CP27 is a letter the IRS sends you if you might be eligible for the Earned Income Tax Credit (EITC) but you didn’t claim it when you filed your taxes. The notices ask you to confirm a few facts about your and your household in order to claim the credit, which could be worth over $6,000. You should fill out the notice truthfully and mail it back to the IRS.
