About the Company

Commonwealth of Massachusetts

State government provides public services

The Commonwealth of Massachusetts runs state government operations to deliver public services and enforce laws for residents and communities. It provides programs and services through agencies and online portals, and residents interact by applying for benefits, renewing licenses, paying fees, or accessing records. Unlike private companies, it is funded by public funds and guided by policy, accountability, and transparency to serve all residents rather than shareholders. Its goal is to improve people’s lives by implementing legislative actions and delivering reliable, efficient public services.
