The income limits for the Supplemental Security Income (SSI) program are probably the most complicated area of SSI. First, income limits vary by state and depend on the amount of your state's SSI supplement. Second, not all of your income is counted when deciding whether you qualify for SSI. For example, more than half of your earned income—wages or self-mployment income—is not counted. Third, part of your spouse's or family income is counted toward the limit. And lastly, if anyone is contributing to your rent or food costs, this can be counted as income toward the SSI limit.
