Unfiled Return Notice (CP59)

Why you might get this

• The IRS expected a return from you for this tax year but hasn't received one.
• Income was reported to the IRS under your Social Security number (like a W-2 or 1099), so they think a return is due.
• You filed late or your return is still being processed, and this notice crossed it in the mail.
• You may not actually have been required to file — but the IRS doesn't know that yet.

The deadline

There's no single printed deadline on this notice, but the IRS wants you to file (or respond) promptly — waiting can cost you a refund and let penalties build.

This notice doesn't carry a fixed response deadline, but it still deserves attention — see what to do below.

What to do

1. Check whether you were even required to file for this year (IRS.gov/WhoShouldFile).
2. If you were required to file, send your return — electronically through an authorized e-file provider, or by mail with payment for any tax due.
3. If you were NOT required to file, complete Form 15103 (Form 1040 Return Delinquency) and mail or fax it back to explain why.
4. Keep a copy of whatever you send and note the date you sent it.

What happens if you ignore it

If you don't file or respond, you may lose your claim to a refund or credits, the IRS can figure your tax for you (usually higher, with penalties and interest), and you could become subject to backup withholding on interest and dividends.

Ignoring CP59 can lead to a Substitute for Return (the IRS files one for you), followed by a balance-due bill (CP14) and the collection path.

Understanding the IRS CP59 notice

A CP59 means the IRS is missing a tax return it expected from you. It's often called a "return delinquency" notice: their records show income reported under your Social Security number for the year, but no return filed against it. The notice is time-sensitive, but it is not a bill and not an accusation — it's a request to either file the missing return or explain that you didn't need to.

Start by checking whether you were actually required to file. Filing requirements depend on your income, age, and filing status, and it's common to get a CP59 for a year you legitimately didn't have to file. If that's your situation, the IRS wants Form 15103 (Form 1040 Return Delinquency) telling them so — you can mail or fax it.

If you did need to file, the fix is simply to file the return, electronically or by mail, including any payment due. The sooner the better: waiting can forfeit a refund you were owed and lets penalties and interest accrue if you end up owing.

The real risk in ignoring a CP59 is that the IRS may prepare a "substitute" return for you — without your deductions or credits — which almost always overstates what you owe and starts the collection process.

Solace can watch your IRS account and translate notices like this into plain next steps, so a missing-return letter never quietly turns into a balance you didn't expect.
