Massachusetts State Supplement Program (SSP)

Information and resources about the Massachusetts State Supplement Program (SSP), a state cash benefit program for qualified Massachusetts Supplemental Security Income (SSI) applicants.

Supplemental Security Income (SSI) is a federal program of the Social Security Administration (SSA) that provides monthly payments to certain eligible, low-income individuals who are age 65 or older, blind or disabled. Massachusetts adds more money to Supplemental Security Income (SSI) payments for Massachusetts residents. Certain individuals found over-income for SSI may still be eligible for a partial benefit from the state. This is called the Massachusetts State Supplement Program (SSP). Massachusetts sends SSP payments to clients directly on the first of the month. The federal government sends SSI payments separately.

The Massachusetts agency responsible for administering the State Supplement Program is the Department of Transitional Assistance (DTA).

Individuals who wish to get State Supplement Program payments must first apply for Supplemental Security Income (SSI) through the Social Security Administration. To find out more about applying for Supplemental Security Income or to inquire about eligibility, contact the Social Security Administration at (800) 772-1213 (or TTY (800) 325-0778 for the deaf and hard of hearing), or visit
