Massachusetts State Supplement Program (SSP)

SSI (Supplemental Security Income) is a federal program of the Social Security Administration that makes monthly payments to certain people who are age 65 or older, blind or disabled. Massachusetts adds more money to SSI payments for Massachusetts residents. This is called the State Supplement Program, or SSP.

Massachusetts sends state supplemental payments to SSP clients directly. The federal government sends SSI payments separately.

The Massachusetts agencies responsible for administering the SSP are the Department of Transitional Assistance and the Massachusetts Commission for the Blind.

More Information:

Applying for SSI and SSP

Individuals who wish to receive State Supplement Program (SSP) payments must first apply for federal Supplemental Security Income (SSI) payments through the Social Security Administration (SSA). To find out more about applying for SSI or to inquire about SSI eligibility, contact SSA at 1-800-772-1213 (or TTY 1-800-325-0778 for the deaf and hard of hearing) or visit

SSP Eligibility and Payments

SSP Eligibility: SSP payments are based on eligibility for SSI payments from the Social Security Administration. In some cases, an individual may have income that is too high for an SSI payment but may still qualify for a payment from the state. Individuals who receive only the SSP payment amount are sent one payment on the first of each month from the state. When SSA makes a federal Supplemental Security Income (SSI) payment, Massachusetts also sends a separate SSP payment.

SSP Payment Amounts:

SSP Payment Methods: SSP payments are made in the same method by which an individual receives SSI payments, either by check or by direct deposit (including SSI Direct Express). SSP payments are made available on the same day as SSI payments. Those who receive both SSI and SSP receive two checks or two direct deposits, one from SSA and one from the state. Those who receive only SSP receive one check or one direct deposit from the state.

Checks: See below for a sample image of an SSP check.

Direct Deposit: The notation that appears with an SSP direct deposit credit on bank statements may include all or part of “COMM OF MASS SSI SUPP”.

SSP Benefit Verification

DTA clients requesting verification of SSP benefits should contact DTA at 1-877-382-2363.

Designated Payees

SSI clients may have a Representative Payee to help them manage their case. SSP clients may have help managing their case from a Designated Payee. Designated Payees receive SSP payments and notices on behalf of clients and should ensure that their contact information on record with SSP is accurate and up to date.

Representative Payees with SSA automatically become Designated Payees for SSP. Clients who only receive SSP payments and wish to appoint a Designated Payee should contact SSP Customer Service at 1-877-863-1128.

Access to SSP Client Record and Information

An SSP client who wishes to authorize another individual to have access to his or her SSP record and information should complete and return a Request for Access to SSP Client Record and Information form. This will give the individual named on the form permission to contact SSP on the client’s behalf to discuss the client’s case. To stop this permission, the client should call SSP Customer Service at 1-877-863-1128.  Request for Access to SSP Record  docx format of Request for Access to SSP Record

Changes to an SSP Client Case

Clients who receive federal SSI payments from the Social Security Administration should notify SSA of any changes to their case, including address, phone number, income and payment method, in accordance with SSA program rules. The Social Security Administration notifies SSP on a daily basis of any changes in SSI cases.

Clients who only receive a payment from the state should contact SSP Customer Service at 1-877-863-1128 to report or request any changes.

Any changes in a client's circumstances that may affect eligibility for SSP or the amount of SSP payments must be reported within ten (10) days.
