The short version
- The IRS holds individual refunds when the account shows at least one unfiled return within the five years before the current tax year that meets the program's criteria.
- You are notified by CP63 or CP88, which tell you to file the missing returns or explain why you were not required to file.
- The hold period is generally six months. If you do not resolve it, the IRS may assess the missing year through ASFR and apply the refund to that balance.
- Filing the missing returns, or showing no filing requirement, is how the refund gets released.
Many people with unfiled years start getting back on track the natural way: they file the current year. If that return shows a refund, they expect a deposit in a few weeks. What arrives instead is a notice saying the IRS is holding the refund because of returns you have not filed.
That is the Delinquent Return Refund Hold program. It is a specific IRS program with written rules, and once you know them, getting your money released is straightforward.
The IRS says it plainly
The IRS page on filing past due tax returns lists this as one of the reasons to file: the IRS holds refunds when "one or more income tax returns are past due." The detailed procedures are in the Internal Revenue Manual at IRM 25.12.1, Processing Refund Hold Program Inventory.
When a refund gets held
According to IRM 25.12.1.1, the IRS holds individual income tax refunds and credit elects when a current or prior year refund return is filed and the taxpayer's account has at least one unfiled tax return within the five years prior to the current tax year that the IRS has flagged as delinquent.
IRM 25.12.1.2 adds that the unfiled year must be one where information return data exists, meaning the IRS received W-2s, 1099s, or similar documents showing income. The program targets unfiled years "with a potential balance due," according to its stated goals.
A few points follow from that:
- The program looks back five years before the current tax year.
- It focuses on years where the IRS has third-party income information.
- It does not hold refunds for prior years that are already barred by the refund statute, because those refunds cannot be paid anyway.
The letters you will get
IRM 25.12.1 identifies two notices used to tell taxpayers their refund is being held:
- CP63, We Have Held Your Tax Refund, Act Now
- CP88, Taxpayer Delinquency Investigation Refund Hold
The manual says these letters "inform the taxpayer the refund is being held because there are delinquent return(s)" and direct the taxpayer "to file the delinquent return(s) or explain why there is no filing requirement."
If you are married and filed jointly, the manual tells IRS employees to research both spouses' accounts. A missing return for either spouse can matter.
How long the IRS holds it
The manual sets the hold period at six months, and it explains why. Under IRC 6532(a)(1), the IRS has six months to consider a refund claim before a taxpayer can sue for the refund. The six months begins on April 15 of the current tax year or the date of filing, whichever is later.
The manual summarizes the program this way: "The refund will be held for 6 months while the IRS requests a filed return from the taxpayer. If no return is received, an assessment may be made through the Automated Substitute for Return (ASFR) program, and the refund applied to any balance due."
In some cases, the hold can be extended beyond six months with management approval, including when the taxpayer asks for more time to gather records or prepare the delinquent returns, requests an Appeals conference, or disputes the reported income (IRM 25.12.1.4).
What happens at the end of the hold
The manual describes two broad outcomes.
The missing returns are filed. A refund will be released if the delinquent returns reflect a refund or even balance, all delinquencies are resolved, there are no balances due, and no other holds apply. If the missing returns show a balance due, the held refund can be applied to that balance. Under IRC 6402(a), the IRS may credit an overpayment against any internal revenue tax liability of the person who made it and refund the rest.
The missing returns are not filed. The manual says Master File will offset held refunds to ASFR cases that have issued a statutory notice of deficiency, and will systemically release refunds if the unfiled modules are not resolved within six months. In other words, if the IRS has moved the missing year through ASFR to a 90-day letter and assessment, your refund will likely be used to pay the IRS's version of that year's tax. See the ASFR 30-day letter.
That is the worst outcome. Your refund pays a bill computed with no deductions, no credits, and no filing status choice.
Why you should not just wait for the release
Some people read that refunds may be released after six months and decide to wait it out. That is a bad bet.
First, the release depends on the delinquent modules not having moved into ASFR with a 90-day letter. If they have, the refund gets applied instead. Second, the missing years do not go away. They remain unfiled, open to assessment under IRC 6501(c)(3), and you still need them filed to be in compliance for any payment plan or offer. Third, if a held refund is for a prior year, the refund statute keeps running.
Interest on held refunds
There is one small consolation. The refund hold manual explains that under IRC 6611(e)(1), no interest is paid on an overpayment refunded within 45 days after the due date of the return, or for a late filed return, within 45 days after it is filed. If the refund is not made within that 45-day period, interest generally must be paid. That is part of why the manual stresses that refund hold cases should be processed promptly. It does not make a hold worthwhile, but it means a held refund that is ultimately released is not simply frozen at its original value.
Joint filers and injured spouse issues
When spouses file jointly and one spouse has unfiled years from before the marriage, a held refund can affect both. The refund hold manual includes procedures for processing injured spouse allocations, and it tells IRS employees to research both spouses' accounts in joint filing situations (IRM 25.12.1.3). If your refund is held because of a spouse's missing returns, make sure the response addresses the right person's account, and ask about injured spouse procedures if your share of the refund should not be used for your spouse's years.
What to do when you get CP63 or CP88
- Read the notice and identify every tax year listed as missing.
- Pull your wage and income transcripts for those years. They show the income documents the IRS has.
- If you were not required to file for a year, call the number on the notice and explain. Have income figures ready.
- If you were required to file, prepare accurate returns for each missing year.
- Send the returns as the notice directs, and keep proof of mailing.
- If you need more time, ask before the six-month hold runs out. The manual allows extended holds in some situations.
- After the returns post, watch for the refund, or for a notice that it was applied to a balance.
The silver lining
A refund hold is irritating, but it is also a gift. It tells you exactly which years the IRS is watching, and it gives you a defined window to fix them before the IRS writes the returns itself. People who respond to a CP63 or CP88 by filing their missing years usually come out ahead of people who wait for the next notice. File the years, get the refund applied or released, and move on.
Frequently Asked Questions
Why is the IRS holding my refund?
Because your account shows at least one unfiled return within the five years before the current tax year that meets the Delinquent Return Refund Hold criteria. The IRS holds the refund while it asks you to file the missing return.
How long will the IRS hold my refund for missing returns?
Generally six months, starting on April 15 of the current year or the date you filed, whichever is later. The IRM allows longer holds in some situations with management approval.
Will I lose my refund if I do not file the missing returns?
You may not get it back. If the IRS assesses the missing year through ASFR after a 90-day letter, the held refund can be applied to that assessed balance.
What if I was not required to file the missing year?
Contact the IRS using the number on the CP63 or CP88. The notices ask you either to file the missing return or to explain why there was no filing requirement.
