When you are awarded Social Security Disability Insurance (SSDI) benefits or Supplemental Security Income (SSI) benefits, the SSA will recommend a review in the future. Depending on the physical disability or mental disorder that is the basis of your award, the SSA will recommend that you undergo a continuing disability review (CDR) anywhere from 1 year to 5 years after the decision.
If the CDR finds either a) that you are working and earning above the substantial gainful activity (SGA) amount or b) that the medical conditions for which you were awarded disability have improved significantly, then the SSA may cut off your disability benefits.
The SSA wants disability beneficiaries to return to the workforce if they are capable. To encourage this, the SSA will allow a nine-month trial work period. During this trial work period you can earn as much as possible with no penalty. If however you have more than 9 months of SGA, the SSA will stop your benefits. You can have your disability benefits reinstated if your medical condition deteriorates and you have to stop working within 36 months from that date.
