CP59 Notice

Unfiled Returns
Action Required
Respond Soon

The CP59 is the IRS's first notice informing you that they have no record of you filing a required tax return. It requests that you either file the missing return immediately or explain why you were not required to file.

Why Did You Receive This Notice?

You received a CP59 because the IRS expected a tax return from you for a specific tax year and has no record of receiving one. This is typically triggered when the IRS receives information from third parties, such as employers or financial institutions, showing you had income in that year, but no corresponding return was filed. Common causes include forgetting to file, believing you did not owe enough to need to file, or an administrative error.

What Does this Mean for You?

The CP59 means the IRS is formally notifying you that a return appears to be missing from their records. If you do not respond, the IRS can prepare a Substitute for Return (SFR) on your behalf, using only the income information they have on file, with no deductions, credits, or exemptions in your favor. This almost always results in a higher tax bill than if you filed your own return.

What Happens If You Ignore It?

If you ignore the CP59, the IRS will file a Substitute for Return for you, calculated at the highest possible tax liability with no deductions or credits. This becomes a formal tax assessment and the IRS will immediately begin pursuing collection. Additionally, the failure-to-file penalty is 5% per month up to 25% of the balance, far more than the failure-to-pay penalty. Ignoring this notice is one of the costliest mistakes a taxpayer can make.

Your Options

  • File the missing return: Even if you cannot pay the taxes owed, filing eliminates the failure-to-file penalty and gives you control over your deductions and credits.
  • Provide proof you already filed: If you did file and the IRS lost it, you can provide a copy of your return and proof of filing.
  • Demonstrate you were not required to file: If your income was below the filing threshold, you can respond explaining why no return was required.
  • Work with a tax professional: If you have multiple unfiled years, a professional can help you strategically file returns in a way that minimizes your overall liability.

Step-By-Step: What To Do Next

  1. Determine whether you were actually required to file for the year in question.
  2. Gather your W-2s, 1099s, and any other income records for that year.
  3. Prepare and file the missing return as soon as possible, even if late, filing stops the failure-to-file penalty from growing.
  4. If you owe taxes on the return, include payment or request a payment plan.
  5. Respond to the CP59 with confirmation that you have filed or an explanation of why filing was not required.

Can You Handle this Yourself?

Filing a late return on your own is possible, you can use tax software or IRS Free File for prior year returns if your income qualifies. The key is to file something, even if it is not perfect, rather than continuing to delay.

FAQ

Q: What happens if the IRS files a Substitute for Return for me?

A: The IRS calculates your taxes using only the income information they have, no deductions, credits, or exemptions. This almost always results in the highest possible tax bill.

Q: Is there a penalty for filing late?

A: Yes, the failure-to-file penalty is 5% of unpaid taxes per month, up to 25%. Filing as soon as possible limits this penalty.

Q: Can I still file a return after the IRS sends a CP59?

A: Yes, and you should. Filing your own return overrides the IRS's substitute return.

Q: What if I cannot afford to pay the taxes I owe?

A: File anyway. You can set up a payment plan after filing. Not filing is far more costly than filing without payment.
