What the IRS says: “The IRS needs documentation supporting items on your return (typically income and withholding) before releasing your refund.” Here’s what it actually means, your deadline, and exactly how to respond.
The actionable sequel to the CP05: the review found something it can't verify, and your refund stays frozen until you prove it. The request list is specific — paystubs, W-2s, 1099s, benefit statements. Complete responses release refunds; partial ones recycle into months of delay.
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.
30 days — to send the requested documentation.
Counted in calendar days from the notice date. The exact respond-by date printed on your notice always controls — check page 1.
Gather EXACTLY what the notice lists — the final paystub of the year is gold for withholding proof
Reply by the deadline (usually 30 days) via the letter's fax/upload channel
Label every page with name, [SSN last 4] and tax year
Employer defunct or won't cooperate: send paystubs + a written explanation
A cover letter mapping each requested item to an enclosed document is the release mechanism. If an employer failed to file, say so explicitly — the IRS has procedures for substitute verification.
Describe the notice and your side of it — use placeholders, never your SSN or account numbers (the letter keeps [YOUR NAME]-style fields so you fill in the real details privately before mailing). A mail-ready draft with an enclosure checklist comes back in ~20 seconds.
