Becoming a foster parent is one of the biggest and most rewarding decisions you can ever make in life. While you do receive supplemental income from fostering children, your family may be eligible for additional benefits. The Social Security Administration (SSA) offers disability benefits for people with serious illnesses, or dependent family members of those with disabilities. There are a few ways children in foster care could be eligible for aid. If Your Foster Child Has a Disability Social Security disability benefits are available to people of all ages. Children will qualify for Supplemental Security Income, or SSI benefits. SSI is only awarded to families in severe financial need, so if you or your spouse has a moderate income, your foster child will not be eligible for SSI benefits. For example, a single parent cannot earn more than $38,000 per year before taxes while having a child qualify for SSI.
