Source: SSA Annual Statistical Supplement 2025, Tables 5.J1, 5.J2 and 5.J4 (December 2024). The average is total retired-worker benefits divided by the number of retired workers; the 2027 figure applies the 3.6% COLA to that average and is an estimate — individual benefits vary widely around it.

SSI in Arizona
Arizona pays no SSI supplement. Your SSI in Arizona is the federal payment only — up to $1,029 a month for an individual in 2027 ($1,544 for a couple). There is no state application, because there is no state program. The full 50-state comparison is on the SSI state supplements page.
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 Arizona tax Social Security benefits?
No. Arizona does not tax Social Security benefits — they are fully exempt from the state income tax. (Federal taxation can still apply — up to 85% of benefits, based on combined income.)
