The Commonwealth of Massachussets Department Of Revenue State data breach

Clerk's notes

The Commonwealth of Massachusetts Department of Revenue State, a key state agency responsible for tax administration and related services, officially reported a data security incident on June 27, 2025. This incident involved the exposure of confidential personal information maintained by the Department.

While the specific details of the incident and the exact types of information affected are part of an ongoing investigation, breaches impacting government revenue agencies frequently involve unauthorized access to taxpayer records and other foundational identifiers.
