How SSDI Converts to Retirement Benefits at Full Retirement Age

Verified against SSA POMS as of September 23, 2026

The short answer

SSDI benefits automatically convert to retirement benefits once a beneficiary reaches full retirement age (FRA). No application is needed for this transition. The FRA depends on birth year, ranging from 65 to 67 years old. The adjustment of reduction factor (ARF) may apply, eliminating certain months from the reduction factor calculation after the transition.

Automatic Conversion from SSDI to Retirement Benefits at FRA

Beneficiaries of SSDI automatically transition to retirement benefits upon reaching their Full Retirement Age (FRA). As per RS 00615.003, the FRA is determined by birth year and ranges from 65 to 67 years.

Reduction Factor Adjustment in the Transition

An adjustment of the reduction factor (ARF) eliminates certain deduction and non-entitlement months from the original reduction factor. This adjustment occurs automatically, meaning no request is necessary by the beneficiary. Relevant policies on ARF are provided in sections RS 00615.480 and RS 00615.482, detailing the conditions for crediting months that influence the adjustment factor.
