Identity, refunds & unfiled returns
The IRS has no record of your tax return for the year named, and it wants one — or your explanation of why you weren't required to file. The nonfiler program restarted at scale: over two million of these went out in FY2025.
Don't sit on it
The IRS has no record of your tax return for the year named, and it wants one — or your explanation of why you weren't required to file. The nonfiler program restarted at scale: over two million of these went out in FY2025.
Why you got it: Income was reported under your SSN (a W-2, 1099s, platform records) but no return arrived — or your return was never received/processed.
Not a bill — yet. But if the IRS decides you owed and never filed, it can build a return for you (a 'substitute for return') with none of your deductions argued, and the clock to claim any refund you were owed is quietly running out (generally 3 years from the filing deadline).
Your first move: Decide which of the three truths is yours: (1) you filed — send a signed copy with proof of filing; (2) you didn't file and should have — file now; (3) you weren't required to — reply with the explanation on Form 15103.
The clock on this letter: File or respond by the date on the notice — immediately is the IRS's word.
The notice's own date controls. The hidden clock: refunds are generally lost 3 years after the return's due date (26 U.S.C. 6511), and there is no time limit at all on the IRS assessing tax for a year never filed (6501(c)(3)).
The complete fix. If a refund is due and the 3 years haven't run, you still get it.
Signed copy + e-file acceptance or certified-mail receipt.
Form 15103 with your income facts if no filing was required.
Mail or fax the return/Form 15103 as the notice directs; the notice can also be answered through your online account's mobile forms.
A CP59 never asks for payment. Anyone who 'found your unfiled return' and wants money by phone is running a script.
Reminders escalate (CP516, then CP518), and the IRS can prepare a substitute return from third-party data — no dependents argued, no credits claimed, worst filing status — then bill you for it.
Where this sits on the ladder: CP518 → CP2566 →
One payment. No subscription. Yours to keep — every notice, every letter, every script.
