Disability payments from private sources, such as private pension or insurance benefits, do not affect your Social Security disability benefits.
However, workers’ compensation and other public disability benefits may reduce your Social Security Benefits.
Workers’ compensation benefits are paid to a worker because of a job-related injury or illness. They may be paid by federal or state workers’ compensation agencies, employers or by insurance companies on behalf of employers.
Other public disability payments that may affect your Social Security benefit are those paid by a federal, state or local government and are for disabling medical conditions that are not job-related. Examples are civil service disability benefits, state temporary disability benefits and state or local government retirement benefits that are based on disability.
If you receive workers’ compensation or other public disability benefits and Social Security Disability Benefits, the total amount of these benefits cannot exceed 80% of your average earnings before you became disabled.
