Hi,
Possibly. If you are drawing Social Security disability benefits (SSDI) and you return to work, you first get a 9 month trial work period during which your benefits continue. If you continue to work and do substantial gainful work (i.e. over $1170 per month in 2017) after the trial work period, your benefits are suspended but not terminated for a period of 3 years. During that time, your benefits can be reinstated if you stop working or your earnings drop below the substantial gainful earnings level.
After the 3 year extended period of entitlement, your benefits would terminate if you are still doing substantial gainful work. Once benefits terminate, you would have reapply and prove that you meet the requirements for SSDI in order to become re-entitled. For more information about working while on SSDI, refer to this Social Security publication: https://www.ssa.gov/pubs/EN-05-10095.pdf.
Best, Jerry
