Beginning January 2009, the maximum monthly Supplemental Security Income (SSI) benefit amount increases to $674 (increased from $637 in 2008) for individuals and 1,010 for couples. The maximum SSI benefit amount is based on the Federal Benefit Rate (FBR).
If you need to know the monthly maximum SSI amounts for other years, this page lists the Federal Benefit Rates back to 1998.
However, your SSI benefits may be less than the FBR amount if you have any other sources of income. For example, if anyone is providing food, clothing or shelter for you — your benefits may be reduced by 1/3.
