SSI in Montana: state supplement, recipients and offices
In December 2025, 15,532 people in Montana got SSI, and SSA paid them $11.0 million that month. The state adds a supplement through SSA for some living settings.
Montana state supplement paid with SSI
Montana is one of 12 places where SSA pays the state supplement together with the federal SSI payment, in one deposit. For someone living on their own, SSA pays no state supplement here; the state part is only for people in the settings below. Through SSA, Montana adds a supplement only for people in state-certified care settings.
| Where the person lives | State part, one person | Total per month, one person | Total, couple |
|---|---|---|---|
| Living in your own home | $0.00 | $994.00 | $1,491.00 |
| In someone else's household that provides your shelter (federal part cut by one-third) | $0.00 | $662.67 | $994.00 |
| State-certified personal care | $94.00 | $1,088.00 | $1,684.00 |
| Group home for people with a mental disability | $94.00 | $1,088.00 | $1,684.00 |
| Group home for people with a physical or developmental disability | $94.00 | $1,088.00 | $1,684.00 |
| Child or adult foster care | $52.75 | $1,046.75 | $1,601.50 |
| Transitional living for people with a developmental disability | $26.00 | $1,020.00 | $1,548.00 |
January 2026 amounts. "n/d" means SSA's table has no amount for that case. Totals add the 2026 federal rate ($994; $662.67 in someone else's household) and assume no other income.
2027: the federal part rises to $1,029 ($1,544 for a couple). SSA had not published the January 2027 state amounts when we checked on Oct. 27, 2026, so the 2027 state part is n/d here.
