You can earn income while waiting for Disability, but earning over a certain amount can put your Disability claim in jeopardy. As of 2022, according to the Social Security Administration (SSA), anyone earning over $1350 a month will probably not qualify for benefits. These rules apply to Social Security Disability Insurance (SSDI) benefits only. For Supplemental Security Income (SSI) applicants, the upper limit depends on where you live, according to the SSI guide published by the SSA.
