IRS & TAXES

What is an IRS CP88 notice and what should I do?

SHORT ANSWER

A CP88 means the IRS is holding your refund because you haven’t filed one or more required tax returns, and it believes you may owe tax. The fix is to file the missing return(s). Once all required returns are in and the IRS confirms nothing else is owed, it can release the refund it’s holding.

A CP88 notice tells you the IRS is freezing a refund because at least one required tax return is missing from your account — and the IRS suspects you may owe tax for the unfiled year. It’s essentially leverage: rather than send you a refund from one year while another year’s return is outstanding, the IRS holds the money until you get current. This isn’t an audit and it isn’t a levy; it’s a refund hold tied to a filing gap. The path forward is straightforward — file the delinquent return. If the missing return is recent (generally within the last two years), you may be able to e-file it; older years usually have to be mailed. If you actually filed it more than about eight weeks ago, the IRS may just be behind, and you can contact them to check. What you shouldn’t do is ignore it: the refund stays frozen until the missing return is filed and the IRS confirms no other tax is due, and an unfiled return can eventually trigger the IRS to file a substitute return for you — rarely in your favor.

What to do, in order

Read the notice to see which tax year’s return is missing and the due date it gives for filing.
File the delinquent return — e-file if it’s within about the last two years; otherwise mail a signed paper return.
If you already filed that return more than eight weeks ago, contact the IRS at the number on the notice to check on processing.
Make sure every required return is filed — the refund stays held until the IRS confirms nothing else is owed.
If you’ll owe on the unfiled year, plan to pay or set up a payment plan so the balance doesn’t escalate.

Common questions

Why is the IRS holding my refund?

Because a required return is unfiled and the IRS believes you may owe tax for that year. It holds the refund from the filed year rather than pay it out while another year is open. Filing the missing return is what releases the hold.

How do I get my refund released?

File all required returns. Once the IRS has them and confirms no other tax is owed, it can release the refund it was holding. If your return was filed more than eight weeks ago, contact the IRS to check status.

What if I don’t file?

The refund stays frozen, and a long-unfiled return can prompt the IRS to prepare a substitute return on your behalf — usually without the deductions or credits you’d claim, which tends to overstate what you owe.
