Frequently Asked Questions — CP59
What is IRS Notice CP59?
CP59 is a notice that the IRS has no record of receiving your tax return for the year indicated. It's a formal demand to file your return or explain why you're not required to file.
What if I already filed the return?
If you filed, gather your proof of filing (confirmation number for e-file, certified mail receipt for paper filing) and send it to the IRS with the CP59 response.
What happens if I ignore CP59?
The IRS will file a Substitute for Return (SFR) on your behalf — with zero deductions and credits. The resulting tax bill will be far higher than if you had filed properly.
Can I still file voluntarily after CP59?
Yes, and you should — immediately. Filing your actual return is almost always better than letting the IRS file an SFR. Penalties for voluntary late filing are lower than IRS-determined assessments.
