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.

If you are approved for SSI, or SSI and SSDI, the rules are different. Social Security generally pays the past-due benefits for SSI or SSI/SSDI in three installment payments that are separated by six months each.
