What the IRS says: “The IRS is reviewing your return's income, withholding and credits and asks you to wait up to 60 days; no action is required.” Here’s what it actually means, your deadline, and exactly how to respond.
An integrity-screening hold (often called the 'CP05 letter's cousin'): the return is being verified against employer filings before the refund releases. Most clear without contact. The frustration is the wait — and the fix for a stuck one is persistence plus, in hardship cases, the Taxpayer Advocate.
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.
Nothing to send — there is no documents channel unless a follow-up letter asks
Verify your own W-2s/1099s were accurate; amend early if not
Mark 60 days; call only after they pass
Genuine financial hardship (eviction, utilities): Taxpayer Advocate Service can force earlier review
No response letter exists for a 4464C itself. If it evolves into a documents request (CP05A/4800C), answer that same-week — the queue position is already paid for.
