If I get social security disability benefits, and I reach full retirement age, will I then receive retirement benefits?
The following answer is from: https://faq.ssa.gov/link/portal/34011/34019/Article/3729/If-I-get-Social-Security-disability-benefits-and-I-reach-full-retirement-age-will-I-then-receive-retirement-benefits
Social Security disability benefits automatically change to retirement benefits when disability beneficiaries become full retirement age. The law does not allow a person to receive both retirement and disability benefits on one earnings record at the same time.
The following answer is Attorney Walter Hnot’s annotated response to the previous answer.
Ok, so here is what you need to know about this. You need to get onto SSDI if you are younger than 65, 66, or 67, aka whenever you would reach full retirement age, as it would allow you to ride the SSDI program without minimizing your percentage towards full retirement. So, if you are on SSDI until you reach your full retirement age, then at that full retirement age, your SSDI will swing over to retirement, and you will receive your full retirement age pension. That’s how you maximize benefits, which is why you are asking this question.
