SSDI Back Pay FAQ
What is SSDI back pay?
Back pay is the benefits you're owed from the end of the 5-month waiting period until your approval date. It's paid as a lump sum.
Why is there a 5-month waiting period?
Federal law requires a 5-full-month waiting period after your disability onset date before SSDI benefits begin. This waiting period is unpaid.
How much is the attorney fee?
Disability attorneys are limited by SSA to 25% of your back pay, with a maximum of $7,200 (2026). They only get paid if you win.
When will I receive my back pay?
Typically 1-2 months after approval. Large amounts may be paid in installments every 6 months.
