HARRISBURG (TNS) — Due to a glitch in the system, some Americans might receive two Social Security payments in August.

And it’s a rare occasion, so feel free to call it a wonky month.

Normally, the Social Security Administration issues one payment each week, and the Social Security checks are delivered on the second, third and fourth Wednesdays of each month. Then it pays Supplemental Social Security Income – which provides support for disabled people and older Americans with low incomes – on the first of the month if it doesn’t fall on a holiday or a weekend.

So, since Sept. 1 falls on a Sunday, SSI recipients are set to get two payments this month, as the first check came on Aug. 1 and the second check will arrive on Friday, Aug. 30, according to the Social Security Administration.

Just to be clear, the back-to-back deposits don’t mean retirees are in store for extra money and they also aren’t missing out on funds by not receiving a payment in September. It just means an early payment for next month.

Much like those who are in store for a three-payday in August, SSI will get the full income they’re expected to by the end of the year. It’s just a bit out of order in August and September.

The same weirdness is set to happen one more time this year, in November, according to a schedule of payments on the Social Security Administration’s website.

SSI recipients are set to receive that month’s payment and December’s payment in the same 30-day span.

In 2025, things will be even more out of order. The first day of January, February, and March all fall on holidays or the weekend. According to the website’s payment schedule, January’s benefits will be issued on Dec. 31, February’s benefits will come a month later, and March’s benefits will be issued on Feb. 28. That leaves no payments in March.

Roughly 7.4 million Americans collect SSI benefits, according to Fox News.
