In addition to paying disability benefits for disabled individuals, Social Security also provides benefits for their minor children and also the spouse (if taking care of non-disabled children under 16 year old or a disabled child of any age).
Ok. How much can a spouse or child get in auxiliary Social Security benefits?
All eligible dependents can receive up to 50% of the wage earner’s (typically the disabled individual’s) benefits. However, the combined total of all benefits (the auxiliary benefits AND the disabled individual’s benefits) cannot be above the family maximum.
So if the disabled individual receives $1,000 per month. Each child may be eligible for $500 per month in auxiliary benefits — so long as the combined total of all auxiliary benefits is under the family maximum.
If the family maximum limit is reached, all auxiliary benefits are equally reduced to bring the total auxiliary benefits within the family maximum limit.
Note: these auxiliary benefits are only available if the disabled individual is receiving Social Security Disability Insurance benefits (SSDI aka DIB). There are no auxiliary benefits (no benefits for spouses or children) for individuals on Supplemental Security Income (SSI).
