Massachusetts offers the second-largest SSI state supplement in the country — $170/month for an eligible individual — trailing only Alaska. Combined with the federal payment, that brings the total to roughly $1,137/month before countable income is deducted.
How the Combined Total Works
The federal SSI baseline for 2026 is $967/month for an individual. Massachusetts adds $170 on top statewide — a substantial supplement reflecting the state's high cost of living, particularly in and around Boston, where rent consistently ranks among the highest in the nation.
💡 SSDI is unaffected by state of residence. Only SSI carries this state supplement, and Massachusetts's is one of the most generous in the country.
Why Massachusetts Pays One of the Largest Supplements
Massachusetts has consistently ranked among the highest-cost states for housing, driven largely by the Greater Boston metro area. The state's SSI supplement reflects an attempt to close that gap, though — as in most high-cost states — the combined total still lags well behind market rent in the most expensive parts of the state, even if it goes further in the western and central regions.
