Working and SSDI Benefits. Generally, you can't start doing substantial gainful activity (SGA) and continue to receive disability benefits. In a nutshell, SGA means you are working and making more than $1,130 per month in 2016 (or $1,820 if you're blind). There are exceptions to this rule, however. For SSDI recipients, there is a trial work period during which you can make more than the SGA amount without losing your benefits. (For a discussion of how much you can work when applying for benefits, see our section on working and eligibility for Social Security disability.)
If you are under full retirement age, you can earn $14,160 per year without incurring a penalty. For every $2.00 over the limit, $1.00 is withheld from benefits. Disability (2010) Most people on Social Security Disability (SSDI) can earn a maximum of $1,000 per month, or $1,640 per month if blind. Any earned income in excess of that amount is considered Substantial Gainful Activity (SGA) and can result in temporary or permanent loss of disability status.
