How much a disable person can get if never worked and under 22 when got disable. I get SSI for the last 3 years only.?

You can't get SSDI unless you've worked and paid into the social security program long enough to be entitled to a benefit. Even then the benefit amount is based upon what you've paid in. Low earnings = low benefit. People who earn around $45,000 a year receive an average benefit of about $1300 a month. It is immaterial what state you live in. SSI and SSDI are federal benefits; the rules and regs are the same nationwide.

You either have the work history or you don't. If you did you'd be getting SSDI as well as SSI because the SSI program requires that anyone who can get another type of income must get it in order to cut down on the costs of SSI which is the federal welfare program.

If you have a parent who receives social security retirement or social security disability benefits or who is deceased and paid into the social security program long enough for benefits to be paid out you can receive benefits as a disabled adult child (DAC - not SSDI) IF there is proof that you were severely disabled before age 22 AND you are unmarried. However if you've worked and earned at least $1090 a month AFTER age 22 you've proven that isn't the case since earnings of $1090 a month or more are considered to be gainful employment.

Consider yourself lucky that you are getting anything. And even if you do become entitled to a social security benefit (SSI isn't social security) it doesn't mean that it would be a high one and it reduces any SSI you get. People who get both SSI and a social security benefit receive no more than $753 between the two combined or $500 if they live in the household of another.

You can not get SSD unless you paid in

SSI is all you are entitled to

If you have never worked, you wouldn't qualify at all.
