There are fourteen states that don't tax pensions and twelve that don't tax distributions from 401(k) plans and IRAs.
Nine of these states have no state income taxes at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. The remaining three — Illinois, Mississippi, and Pennsylvania — don’t tax distributions from 401(k) plans, IRAs, or pensions. Alabama and Hawaii don't tax pensions, but these states do tax distributions from 401(k) plans and IRAs.
