In 2026, you must identify the issuing agency, check the right search system, and request a replacement payment. The Bureau of the Fiscal Service via TreasuryDirect describes canceled federal payments. It returns the money to the relevant agency for reissue after your direct claim.

Why does a Treasury check expire?
Treasury checks carry a Void After One Year legend for paper payments. The Cornell Legal Information Institute publishes current eCFR text stating Treasury will not pay checks presented more than 12 months after issue. Banks must decline checks issued more than one year before presentment.
The Federal Aviation Administration explains that voided proceeds return to the issuing agency. That agency can reissue payment only within six years of original issue under the Barring Act, 31 U.S.C. 3702(b).
Where does the money go after cancellation?
The Bureau of the Fiscal Service via TreasuryDirect describes canceled federal payments. When it learns a payment cannot be delivered, was not cashed in time, or was returned, it cancels the payment.
It returns the money to the relevant agency for reissue after your direct claim. You cannot collect the canceled amount from the bank or check-cashing service. You must ask the agency that authorized the original payment to reissue it.
Where should you search first?
The Bureau of the Fiscal Service via TreasuryDirect states there is no governmentwide central source for unclaimed federal money. Each agency keeps its own records. Its unclaimed money FAQs say you must identify the specific asset, expected date and method, and responsible agency.
The National Association of Unclaimed Property Administrators points to free searches on MissingMoney.com. It says to check every state where you lived or worked. Federal payments still need separate agency searches because no central federal database exists.
How do you claim an IRS or Social Security replacement?
The Internal Revenue Service outlines a refund trace for missing refund checks. Its refund inquiry guidance lists online, phone, and form options for starting a trace. The Internal Revenue Service says a traced check that was not cashed is canceled for replacement.
If it was cashed, the Bureau of the Fiscal Service sends a claim package with a check copy. You complete the package, then the Bureau compares signatures and decides on replacement. The Social Security Administration POMS says Treasury generates Form FMS-1133 after SSA enters a Title II or XVI nonreceipt or stop-payment request. Answer its forgery questions and return it promptly for Treasury adjudication and possible replacement.
