There is going to be an increase in the SSI amounts people will receive in 2014:

With the increase, the maximum federal benefit for an individual receiving SSI will rise from $710 per month to $721. At the same time, the federal ceiling for a couple on SSI will grow from $1,066 per month to $1,082. Many states add to SSI benefits for their residents meaning that actual payments could exceed these caps.
