Funded by general tax revenues as opposed to Social Security taxes, SSI provides monthly financial support covering eligible people’s basic needs. Those eligible for SSI are typically disabled, blind, or 65 and older with limited income and assets. As the monthly amount received is subject to a person’s financial resources, such as accommodation and income, extensive documentation related to these resources are to be submitted when applying for SSI. When attempting to receive SSI due to a disability, evidence of medical history must be provided.
