Retroactive Benefits
Social Security back payments, often referred to as retroactive benefits, cover disability payments for months that you were deemed eligible but were not receiving them. These payments typically track back to your established disability onset date.
Since SSDI is a long-term disability program, there is a mandatory 5 (five) month waiting period to ensure individuals have a long-term disability. That date starts from your onset date and must accumulate a total of five full months. For example, if Social Security deems a disability began on June 15, 2025, with an application date of July 1, 2024, then benefits will start paying beginning December 2024. This is considered the sixth month of full disability. The only exception to this waiting period is individuals diagnosed with Amyotrophic Lateral Sclerosis (ALS).
Retroactive benefits will pay individuals back a maximum of 12 (twelve) months in back pay, regardless of when an individual was disabled and stopped working. Benefits, both retroactive and ongoing, are determined by your Average Indexed Monthly Earnings (AIME) and are calculated using a specific formula to calculate your Primary Insurance Amount (PIA).
When your claim is approved, back pay arrives in one of two ways:
- Lump Sum Payment: The full amount comes in one payment.
- Installments: If SSDI is combined with SSI back pay, the SSA may distribute the retroactive funds in smaller payments over time to avoid overpayments or financial strain.
