yes they are federal but each state deals with it a different way.

example in NY the state adds like $25.00 -$45.00 to ithe federal amount because of the sales tax is counted in for cost of living. in california their state adds less than what NY does to account for their cost of living of taxations, oregon state doesnt add any to account for state tax because there is no state tax in oregon on food, clothing and shelter needs. nevada adds a smaller amount then NY and california does.

some people in NY get up to $800.00 and others in NY get $674.00. it all depends on work elligability, experience, each persons own needs, outgoing bills vs assets and a whole lot of other things.

each case is different and each state is different.

the only way to know for sure what each person is allowed for their SSI/SSDI benefits and what their income allotment is without being penalized by social security is by contacting your areas social secrutiy/disability office. they will let you know where things stand in your state area and for your particular situation.
