People who receive Supplemental Security Income (SSI) are about to get the first of two payments for September starting this week.

SSI payments are issued every month, but September is one of three months in 2022 where payments are issued twice in a single month, according to the Social Security Administration’s schedule (pdf). Some will get two payments of up to $841 on Sept. 1 and Sept. 30, meaning $1,682 will be doled out this month.

Some months start on a Sunday therefore SSI recipients will receive a payment twice  including September, and December.

The SSI payment that’s being sent out on Sept. 30 will replace the one that would have been sent on Oct. 1, meaning that no SSI checks will go out in October.

The schedule shows that two payments will be made in December 2022 as well. One will come on Dec. 1 and the other on Dec. 30. Earlier this year, two checks were sent out in April.

Currently, according to the Social Security website, the maximum federal amount for 2022 is $841 for an eligible individual, $1,261 for an eligible individual with an eligible spouse, and $421 for an essential person every month. An “essential personal” is defined by the government as an individual who lives with an SSI recipient and provides them with care.

SSI payments are made to people age 65 and older without disabilities who meet the financial qualifications, according to the federal government, and are designed to provide “monthly payments to adults and children with a disability or blindness who have income and resources below specific financial limits.”
