Retroactive Payments. The SSDI retroactive payments are payments made to disability applicants for the time passed between the onset of the disability to the date that the application was passed. Retroactive payments are paid for 12 months prior to the date of the application being passed.
The total amount of retroactive and/or back due benefits you receive can be impacted by your application date and waiting period. If you are eligible for Social Security disability benefits, there is a five month waiting period before SSA will begin your benefits. This means that your first benefit payment begins on the sixth month after the date SSA finds your disability began.
