Can I get SS disability benefits after I start receiving SSI?
Hi. My answer assumes that by SSI you're referring to Supplemental Security Income. Yes, it's possible to become eligible for Social Security disability (SSDI) benefits even if you're already collecting SSI benefits, provided that you're under your full retirement age (FRA).
However, you can only qualify for SSDI benefits if you meet the insured status requirements. To be insured for SSDI, you must basically have at least the equivalent of 1 quarter of coverage (QC) for each year elapsing from the year you turned age 22 to the year you became disabled. And, if you're at least age 31, you must also have at least 20 QCs within the 40 quarter (i.e. 10 year) period that ends with date you became disabled. Fewer QCs are required for people who become disabled prior to age 31.
If you do become entitled to SSDI benefits, Social Security would offset your SSI payments roughly dollar for dollar by the amount of your SSDI benefit. SSI is a needs based benefit, so receipt of other income such as SSDI benefits can cause a person's SSI payment amount to be reduced.
If you think you might be eligible for SSDI benefits, you may be able to apply online at ssa.gov (https://www.ssa.gov/benefits/disability/). If you're unable to apply online, you can call Social Security to make an appointment to apply by phone.
