A US tax agency has compromised taxpayers’ personal information by missing a lengthy data breach that lasted 18 months.
The Oklahoma Tax Commission (OTC) says the breach occurred between July 2024 and December 2025, according to a new submit with the Maine Attorney General’s Office.
The agency didn’t notice the suspicious activity until December, noting that there was unauthorized access to certain W-2 and 1099 files on their online taxpayer portal.
The filing shows that names and Social Security numbers were stolen in the breach, although the OTC did not disclose the total number of individuals affected.
The agency says it is “continually committed to the privacy of the information in its care” and that it will review its existing security standards.
“Information privacy and security are among the OTC’s highest priorities. The OTC’s response included completing an investigation, working with the Internal Revenue Service (“IRS”) to continue the investigation so it can monitor fraudulent tax return activity, and conducting a comprehensive review of the open files to determine which individuals are involved in the incident.”
The OTC also says it will provide access to credit monitoring and identity theft protection services for one year through Cyberscout, a TransUnion company.
