This proposed legislation aims to significantly reform the Supplemental Security Income (SSI) program by excluding in-kind support and maintenance from income calculations. Currently, non-cash assistance like free rent or food can reduce a recipient's cash benefits, creating administrative burdens and potentially lowering aid. The bill amends Section 1612(a)(2) of the Social Security Act to explicitly disregard such support as income, simplifying eligibility determinations. Additionally, it includes conforming amendments to other sections of the Act to ensure consistency and clarifies how cash support from sponsors is treated for certain aliens. These changes are intended to streamline the SSI program, potentially increasing benefits for eligible individuals, and will take effect one year after enactment.
