I saw a chart of the 50 states and how each funds benefits differently. That is, states like Connecticut, California, Alaska gave more –
but does that count towards SSI only? Or also SSDI?
That is do SS disability (SSDI) payments vary based on what state you live in? (Do states match federal payments on that?)
Social Security Disability Insurance benefits are based solely on the amount of credits earned and taxes paid into the federal system. You would receive the same SSDI benefit regardless of where you lived. Supplemental Security Income is a fixed federal amount plus any additional amount added on by the state, and is subject to adjustment for any other income, including SSDI, to which you may be entitled. If your SSDI benefits are greater than the total SSI benefits pable in your state, than you would not receive any SSI benefits (although you may qualify for other state benefits based on your disability).
For example (plucking figures out of thin air, since I don’t know the current rates offhand) if you are entitled to monthly SSDI benefits of $351.00 and the combined federal & state SSI rate where you live is $521.00, you would receive monthly SSI benefits of $190.00 (there’s a $20.00 allowance involved, which is why you get $190.00 instead of $170.00). However, if your SSDI benefit was $720.00, you would not receive any SSI benefits.
