Ordinarily, disability payments from other sources do not affect your Social Security disability benefits. However, if the disability payment is worker's compensation or another public disability payment, your and your family's Social Security benefits may be reduced.

Your Social Security disability benefit will be reduced so that the combined amount of the Social Security benefit you and your family receive plus your workers' compensation payment and/or public disability payment does not exceed 80 percent of your average current earnings. (Note that the unreduced benefit amount is counted for income tax purposes.)
