SSI in Connecticut
Administered by the state. Connecticut runs its own supplement program: applying for SSI does not by itself start the supplement, you apply through the state agency, and it is paid separately from the federal SSI payment.
Amount: Connecticut sets its own supplement amounts, which vary by eligibility category and living arrangement. SSA does not publish a single standard figure for state-administered programs, so check the current amount with your state agency before budgeting around it. How every state compares: SSI state supplements.
The federal part is the same everywhere: a 2027 maximum of $1,029 (individual) / $1,544 (couple), first increased payment December 31, 2026. Federal amounts by living arrangement are on the SSI calculator and dates on the SSI payment schedule.
Does Connecticut tax Social Security benefits?
Yes — Connecticut is one of the eight states that still tax Social Security benefits in 2027. Connecticut fully exempts benefits when AGI is below $75,000 (single) / $100,000 (joint). Above those thresholds the exemption phases down, and no more than 25% of benefits are ever taxed.
