Some Social Security beneficiaries won’t receive a payment this month. The reason? It’s all about the calendar.

People who receive Supplemental Security Income, or SSI, won’t receive any payments in September after receiving two in August – Aug. 1 and Aug. 30. Typically, SSI payments are made on the first of each month. However, Sept. 1 fell on a Sunday this year so payments were made on Friday, Aug. 30. The next round of checks won’t be delivered until Oct. 1.

Similar payment changes were made in January, when the 1st fell on a Monday but was the New Year’s Day holiday, and in June, when the 1st fell on a Saturday, pushing the payment back to May 31st.

Another calendar change-up will occur in November when recipients will get two payments – one on Nov. 1 and another on Nov. 29 because Dec. 1 falls on a Sunday. December will have another distribution date, however, on the 31st to cover the January 2025 payment since the 1st is New Year’s Day. You can see the complete 2024 payment calendar here.

Some 7.5 million people receive SSI payments each month, including nearly 2.4 million people ages 65 and older. Recipients are older, blind or have a disability and have low income. While Social Security administers SSI it does not pay for it, AARP explained. General Social Security benefits are funded through Social Security taxes paid by working people. SSI primarily comes from the U.S. Treasury general revenue with supplements provided by states.

To qualify, you must be at least 65 years old, blind or have a disability and have very limited financial resources. In 2024, the maximum monthly benefit available from federal funds is $943 a month for an individual or $1,415 for a couple who are both eligible for the program.
