What the IRS says: “The IRS is holding your refund while it reviews the accuracy of your return — no action required yet.” Here’s what it actually means, your deadline, and exactly how to respond.
A CP05 means the return tripped a filter (withholding verification, refundable credits, income matching) and a human review is queued. Most CP05 reviews release within 60 days without any taxpayer action. The follow-up to watch for is a CP05A, which DOES request documents.
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.
Verify the return's accuracy against your documents now — if something IS wrong, amending early beats the audit path
Wait the stated window (typically 60 days) — calling earlier rarely accelerates
Watch the mail for a CP05A documents request and answer it fast
After 60 days with nothing: call, and consider the Taxpayer Advocate for hardship
No response is possible until the IRS asks for something — the CP05 stage has no documents channel. The moment a CP05A lands, a complete, indexed reply is what releases the refund.
