# How is SSDI back pay paid out?

In some circumstances back pay can be released in installments, and any offsets (workers' compensation, prior overpayments) are applied before payment.

**Direct answer:** SSDI back pay is generally paid in one lump sum by direct deposit after the SSA finalizes your award, with attorney fees (if any) withheld and paid directly to your representative under fee-agreement rules.

## Is back pay lump-sum or installments?
For SSDI, back pay is usually a single lump sum; installment rules that apply to large SSI back pay generally do not apply the same way to SSDI.

## How are attorney fees paid?
Under an approved SSA fee agreement, the SSA withholds and pays the representative's fee directly out of past-due benefits, up to the statutory limit.

## What offsets apply?
Workers' compensation and public-disability benefits can reduce SSDI back pay, and prior overpayments can be recovered from it.
