CP88 Notice

Unfiled Returns
Action Required
Respond Soon

The CP88 is an IRS notice informing you that your tax refund is being held because you have not filed a required tax return for a prior year. The IRS will not release your refund until the unfiled return is submitted and any resulting balance is resolved.

Why Did You Receive This Notice?

You received a CP88 because the IRS determined that you have a required but unfiled tax return from a prior year. The IRS is holding your current-year refund as leverage to encourage you to file. The IRS believes you may owe tax for the unfiled year, and releasing your refund before the prior year is resolved could result in an uncollectible balance.

What Does this Mean for You?

The CP88 means your refund is frozen until you file the missing return. If the missing return results in a balance due, the IRS will apply part or all of your refund to that balance before releasing any remaining amount. If no tax is owed for the prior year, your full refund will be released after the return is processed.

What Happens If You Ignore It?

If you ignore the CP88, your current refund will remain frozen indefinitely. Additionally, the IRS will likely file a Substitute for Return for the unfiled year — typically resulting in a higher tax liability than you would calculate yourself — and use your current refund to offset that balance.

Your Options

  1. File the missing return: The fastest way to release your refund is to file the prior-year return as soon as possible. Once processed, the IRS will determine your liability and release any remaining refund.
  2. Request transcripts: If you've lost your income documents for the prior year, request a Wage and Income Transcript from the IRS at irs.gov to reconstruct the return.
  3. Contact the IRS: If you believe you did file the missing return and the IRS is in error, call the number on the notice to investigate.

Step-By-Step: What To Do Next

Step 1: Read the CP88 and note which tax year has the missing return.

Step 2: Gather all income documents for the missing year — W-2s, 1099s, etc. Order IRS transcripts if documents are unavailable.

Step 3: File the missing return as soon as possible.

Step 4: If the return shows a balance due, pay it or set up an installment agreement.

Step 5: Once the IRS processes the prior-year return, your current refund will be released — usually within 6–8 weeks.

Can You Handle this Yourself?

Filing a prior-year return is very manageable on your own if you have the income documents. Most tax software allows you to file prior-year returns. If you've lost documents, the IRS Wage and Income Transcript is a reliable substitute that shows all income reported by employers and financial institutions.
