In order to receive concurrent benefits, there are going to be two separate tests. The standard to receive benefits medically is the same in both programs. The difference between the two programs is your work history and income level. In order to qualify for SSDI, you must have worked for the last five years and paid into the Social Security system. If you qualify for SSDI and your monthly compensation is less than the maximum amount, currently $783, you could be eligible under the SSI program. Remember, you must qualify for each one individually. In order to qualify for SSI, you must not have income greater than the maximum nor can your net worth be greater than $3,000. This looks at both your income and your household income.
For example, if you were receiving $500 for SSDI, you could qualify for $283 under the SSI program.
