IRS Notice CP59 — the IRS has no record of your prior-year tax return
A CP59 means the IRS believes a personal tax return was required for a prior year and has no record of one — often because employers or banks reported income under your SSN or ITIN. It asks that the return be filed immediately, or an explanation given of why none is needed.
How serious: needs actionAlso called: CP59, unfiled return notice, delinquent return notice
The IRS sends a CP59 when it has no record of a personal tax return for a prior year it believes you were required to file — typically because income was reported under your SSN or ITIN by employers or banks.
The notice asks for the missing return to be filed immediately, or an explanation of why filing is not required. Form 15103 (Form 1040 Return Delinquency) comes with it for that explanation.
People living abroad often receive it for years when they had US income but did not realize a filing was required. The notice is how the IRS asks the question directly.
Who sends it
The Internal Revenue Service (IRS) — the United States federal tax authority, part of the Department of the Treasury.
The code 'CP59' is printed in the top corner, with wording like 'We have no record that you filed your prior year personal tax return'. The notice includes Form 15103 (Form 1040 Return Delinquency), to complete if you believe you were not required to file.
The deadline
File the return or respond immediately — 'File your personal tax return immediately or explain to us why you don't need to file' (IRS CP59 page); no fixed day-count is stated
The notice asks that the personal tax return be filed immediately, or an explanation given of why no filing is needed. No fixed day-count is stated: the instruction is 'immediately', counted from the date printed on the notice.
If you do nothing
Penalties and interest continue to accrue until the return is filed and paid in full. Claims to a refund or certain credits can be lost, because the Internal Revenue Code sets strict time limits — generally a return must be filed within 3 years of its due date to claim a refund. If filing still does not happen, the IRS may file a substitute return that might not give credit for deductions and exemptions you are entitled to, followed by a Notice of Deficiency CP3219N (a 90-day letter) proposing a tax assessment.
How it escalates
- 01Penalties and interest continue to accrue until the return is filed and paid in full.
- 02Refunds and credits are lost once the statutory claim window closes — a return must generally be filed within 3 years of its due date to claim a refund.
- 03The IRS may prepare a substitute return without most deductions and exemptions and issue a Notice of Deficiency CP3219N — then 90 days to file the past-due return or petition the Tax Court.
- 04The assessed tax is collected via lien and levy; repeated non-filing can bring additional enforcement measures, such as additional penalties and/or criminal prosecution.

What makes it count
CP59 prints no fixed response date — the instruction is to file 'immediately' — so there is no deadline for IRC §7502 to protect; what is time-critical is the three-year window from the return due date to claim any refund for that year. Form 15103 goes to the address or fax on the notice, or through the IRS Online Account; the return itself goes to the filing address for that form and year, or is e-filed where the year permits. Keep proof of filing, since a late return that reaches the IRS unrecorded restarts the whole sequence.
Common questions
Why did a CP59 arrive if I live abroad?
The IRS sends it when income was reported under your SSN or ITIN for a year it believes required a return. People abroad often receive it for years with US income where they did not realize a filing was required.
What if I was not required to file at all?
Form 15103 (Form 1040 Return Delinquency), which comes with the notice, exists to explain exactly that — or to say a return was already filed.
Can a refund still be claimed for that old year?
Generally only if the return is filed within 3 years of its due date. Once that statutory window closes, the refund claim is lost.
What is a substitute return?
A return the IRS may prepare on its own if none arrives. It might not give credit for deductions and exemptions you are entitled to, and it is followed by a Notice of Deficiency CP3219N with a 90-day window to file the past-due return or petition the Tax Court.
