Who we serve
DOR serves all Massachusetts taxpayers as well as out-of-state businesses and individuals with tax obligations to our Commonwealth.
We assist parents who pay and receive child support and help cities and towns manage their finances. We are also in charge of the Underground Storage Tank Program, which helps gas station owners pay for environmental safety improvements.
