The Oklahoma Tax Commission (OTC) recently reported a data breach involving unauthorized access to personal information through the Oklahoma Taxpayer Access Point (OkTAP) system. The breach, which affected 14 Maine residents, involved sensitive data such as Social Security numbers and names. The breach occurred over a span of several months between July 5, 2024, and December 20, 2025, and was discovered in March 2026.

Oklahoma Tax Commission’s Data Breach Investigation

In December 2025, the OTC discovered suspicious activity within the OkTAP system. Upon learning of the issue, the OTC promptly initiated an investigation with the assistance of third-party cybersecurity experts and digital forensics specialists. The investigation revealed that unauthorized access had occurred to certain W-2 and 1099 files containing sensitive personal data, including names and Social Security numbers, between July 5, 2024, and December 20, 2025.

In response, the OTC took several steps to address the situation. The agency cooperated with the IRS to monitor for fraudulent tax filing activity, and a comprehensive review of the affected files was conducted to identify the impacted individuals. The OTC also reviewed its security standards and implemented additional safeguards to prevent future incidents.

On March 27, 2026, the OTC notified the affected Maine residents, informing them of the breach and the steps being taken to protect their personal information.

The breach occurred between July 5, 2024, and December 20, 2025, when unauthorized access was gained to the OkTAP system. The breach was discovered by the OTC on March 10, 2026.

What Information Was Breached?

The data breach involved the following types of personal information:
