The Social Security Administration denies disability benefits to people who return to work and people who are no longer disabled, according to its official website. Disability benefits stop when a person is incarcerated, states Nolo. A convicted felon who does not serve time may also lose disability benefits.
A person who receives Social Security disability benefits must advise the Social Security Administration if he returns to work or his medical condition improves, explains the Social Security Administration. A person who works at a "substantial" level under Social Security guidelines is no longer eligible to receive disability benefits. As of 2015, Social Security denies disability benefits to a person who earns $1,090 or more per month or $1,820 per month for a person who is blind.
The Social Security Administration must periodically verify a person is still disabled. This involves a Continuing Disability Review, states Nolo. The Social Security Administration sends a CDR notice to the disabled person asking for information regarding his daily activities and medical treatment. If the review finds the beneficiary's condition has improved to the point he can work, disability benefits end. CDRs generally take place every three or seven years depending on the severity of the medical condition and the likelihood of improvement.
