Disability payments from private sources, such as private pensions or insurance benefits, don’t affect your Social Security disability benefits. Workers’ compensation and other public disability benefits, however, may reduce what you receive from Social Security. Workers’ compensation benefits are paid to a worker because of a job-related injury or illness. These benefits may be paid by federal or state workers’ compensation agencies, employers, or by insurance companies on behalf of employers.
Public disability payments that may affect your Social Security benefits are those paid from a federal, state or local government for disabling medical conditions that are not job-related. Examples of these are civil service disability benefits, state temporary disability benefits, and state or local government retirement benefits that are based on disability. A few states, including New York and California, offer temporary disability benefits alongside their unemployment insurance programs. You can receive state disability insurance payments at the same time as SSDI, but your SSDI may be “offset” by these short-term disability payments.
Veterans Administration benefits don’t affect your Social Security disability benefits.
