What CP80 actually means

Money is sitting on your account (withholding, estimated payments) with no return to attach it to. File within 3 years of the due date or the credit is forfeited to the Treasury — permanently. CP80s spiked when paper returns went unprocessed; sending proof of the original filing avoids double-filing chaos.

Notice family: Refund Holds & Unfiled Returns — Your refund is frozen or the IRS has no return on file for a year it expected one. These resolve by filing, verifying, or sending exactly the documents requested — silence makes them worse.
