TIGTA Watchdog: IRS Couldn’t Match $3.2 Billion in Taxpayer Payments to Accounts
A new report from the Treasury Inspector General for Tax Administration (TIGTA) finds that the IRS received $3.2 billion in unidentified taxpayer payments between fiscal years 2022 and 2024. These are funds the agency could not immediately match to a specific taxpayer account due to missing or incomplete information on the payment. Roughly $2.3 billion (about 70%) was eventually applied to the right accounts. But $218 million remained unresolved, and another $741 million was removed from inventory or transferred to excess collections after sitting unmatched for a year. For Americans abroad, who already rely on paper checks, international wires, and slower foreign mail more often than U.S.-based filers, the findings are a clear signal to tighten up how you document every payment to the IRS.
What TIGTA Found
The May 21, 2026, report uncovered chronic, low-tech tracking inside the agency:
- IRS employees still track unidentified payments using spreadsheets and paper files, with cases assigned and monitored manually, and sometimes containing missing or inaccurate information.
- The agency does not centrally manage unidentified payment inventory. Cases are tracked separately across three tax processing centers using independent systems.
- Workloads are uneven. The Ogden, Utah, center handled about 40% of unidentified payment inventory with the same staffing as the Kansas City, Missouri, center, which handled roughly 11%.
- TIGTA found that “program management controls are not sufficient” for measuring timeliness, and the IRS does not currently have timeliness criteria for resolving these cases.
- Of the 302.6 million payments the IRS received in calendar year 2025, 41.4 million were still on paper, even after Executive Order 14247 directed federal agencies to move away from paper-based payments.
The IRS agreed with TIGTA’s recommendations and says it is building an electronic case management system. In the meantime, it has rolled out an interim process to track its backlog of “hardcore payment tracers,” which are the most stubborn missing-payment cases.
Why This Hits Americans Abroad Harder
If you live overseas, a payment to the IRS typically travels farther, often through more hands, and is often still on paper. That increases every risk the TIGTA report flagged:
- Foreign mail delays mean checks can arrive late or with damaged or unreadable identifying information.
- International wires can land at the IRS without a clear taxpayer identification number (TIN) or tax period if the originating bank’s reference fields are limited or get reformatted in transit.
- Time zone and phone constraints make it harder to reach an IRS agent from abroad if a payment disappears from your account.
- Notices and penalties can stack up while a payment sits in the unidentified pile, even though you sent the money on time.

What You Should Do Next
You cannot fix the IRS’s back office, but you can keep your own payments out of the unidentified pile.
- Pay electronically whenever possible. Use IRS Direct Pay for individual payments from a U.S. bank account, or enroll in EFTPS for business and estimated payments.
- Always include your full TIN and tax period. Whether you are paying by check, wire, or electronically, list your Social Security number or ITIN, along with the exact tax year and form (for example, “2025 Form 1040”) on every payment.
- Keep proof for every payment. Save the confirmation number, bank wire record, canceled check image, or Direct Pay receipt. Hold these for at least three years after filing.
- Check your online IRS account about two to three weeks after each payment. Confirm the payment posted to the correct tax year by reviewing your IRS online account.
- Act early if a payment goes missing. If a payment does not appear on your account or transcript within a few weeks, contact the IRS with your proof of payment so the agency can begin a trace. The longer an unidentified payment sits, the higher the chance it ends up in the $741 million pile that the IRS moves to excess collections after one year.
If you are catching up on multiple years or are not sure whether prior payments were posted correctly, this is a good moment to pull every transcript and reconcile it against your records before another notice arrives.
