Taxpayers who never filed a return for a year in which the government owed them money have three years from the original due date to file and collect it, and after that the money becomes the property of the U.S. Treasury, according to the Internal Revenue Service. For tax year 2022 that window closed with an April 15, 2026 deadline, and the IRS estimated that over 1.3 million people had left about $1.2 billion in refunds unclaimed.
The rule is a statute-of-limitations clock the IRS calls the Refund Statute Expiration Date. It is set separately for each tax year.
Retirees who skipped filing in a low-income year, workers whose employer withheld tax and people who were never required to file are the ones most likely to have a year sitting open. For them the question is which tax years are still inside the three-year window and which have already passed.

$1.2 billion went unclaimed for tax year 2022
In its March 20, 2026 release IR-2026-37, the IRS said the median unclaimed refund for 2022 was $686. The state-by-state table in the release adds up to 1,322,600 estimated individuals and about $1.16 billion, a total the agency rounds to $1.2 billion.
The IRS said “under the law, taxpayers usually have three years to file and claim their tax refunds.” It added that if they do not file within three years, the money becomes the property of the U.S. Treasury.
By the same three-year count, the next tax year in line, 2023, runs out in April 2027, a deadline that is still ahead.
The clock starts at the due date for anyone who never filed
An IRS video script on the topic puts it this way: if a taxpayer does not file a return claiming a refund within three years, the refund is lost, and that is three years from the original due date, usually April 15. The script says missed refunds are often several hundred dollars, and that the Earned Income Tax Credit could be a few thousand dollars.
The IRS page on the time limit states the general rule for filers as the later of two dates. The latest date to claim a refund is three years from the date the return was filed, or two years from the date the tax was paid, and a return filed before its due date counts as filed on the due date.
The page was last updated June 27, 2026. For a person who has filed nothing, the filing date does not exist yet, so the original due date is the starting point.
Withholding counts as paid on the due date
Tax taken out of a paycheck or pension is treated as paid on the due date of the original return, not on the day it left the paycheck. The Taxpayer Advocate Service, an independent office inside the IRS, says withholding and estimated payments are treated as paid on the due date of the original return, not counting extensions.
The advocate service lists the Earned Income Tax Credit, the Additional Child Tax Credit and the Premium Tax Credit as refundable credits that can produce a refund even when little tax was withheld. Its April 9, 2026 article describes the filing of past-due returns before the refund date expires.
A refund is not the same as a return, so the IRS cannot send money for a year in which no return exists. The return itself is the claim, and it has to arrive inside the window.
Unfiled later years can hold a refund back
The release on 2022 returns carries a second warning. It says 2022 refunds may be held if the 2023 and 2024 returns are also unfiled, so a person with several open years may need to bring them all current.
The IRS page on the time limit frames the deadline the same way for each tax year: the latest date, by law, to claim a credit or refund for a specific tax year is set year by year. A person with more than one missing return therefore has more than one date to track.
Is there a year of work or retirement income with no return filed?
The clock for that year started on its original due date.
Each unfiled year has its own date, and the oldest one in the window is the next to close. A refund that passes the line stops being the filer’s money and becomes the Treasury’s.
“The IRS Refund Recovery Kit” is a 20-page guide that includes the 3-year refund deadline, so a reader can see where each year stands against the window. It also has a refund status and notice tracker spreadsheet for following a refund after the return goes in.
The guide covers the situations that follow a filed return, such as identity verification in Part 5 and refunds that were sent but never arrived in Part 7.
