Social Security will pay December benefits on Dec. 3, 9, 16 and 23, depending on a person’s birth date and when benefits began, while Supplemental Security Income (SSI) recipients are paid on Dec. 1, according to the agency’s payment calendar page. The dates follow a fixed pattern: Wednesday paydays for most retirees, and set days of the month for people who also get SSI or have collected since before May 1997.
That puts a plain question on every household that counts on a monthly deposit for rent, medication or a utility bill: which group is mine? The answer depends on the day of the month a person was born, or on whether the person also receives SSI or started collecting Social Security more than a quarter century ago. The rest of the schedule follows from those two facts.

Which Wednesday is yours?
Most beneficiaries are assigned to one of three Wednesdays. Under the 2026 payment schedule PDF, people born from the 1st through the 10th are paid on the second Wednesday of the month, which is Dec. 9. Those born from the 11th through the 20th are paid on the third Wednesday, Dec. 16, and those born from the 21st through the 31st on the fourth Wednesday, Dec. 23.
A retiree born on Dec. 12 would see a deposit on Dec. 16, while someone born on March 28 would be paid on Dec. 23. December has five Wednesdays, Dec. 2, 9, 16, 23 and 30, and only the 9th, 16th and 23rd are Social Security paydays for these groups. The first and last Wednesdays of the month are not.
The cutoffs matter at the edges. A person born on the 10th is paid a full week earlier than a person born on the 11th, and a person born on the 20th is paid a week earlier than one born on the 21st. Two neighbors with birthdays a day apart can see their deposits land on different Wednesdays.
Who is paid on the 3rd instead?
The schedule sets aside a second group. People who received Social Security before May 1997, and people who receive both Social Security and SSI, are paid on the 3rd of the month no matter what day they were born. In December the 3rd is a Thursday.
That means a retiree who began collecting in the early 1990s and was born on the 25th follows the 3rd, not the fourth Wednesday. Anyone unsure which group applies can look at the date their last few deposits arrived: a deposit on the 3rd points to this group, and a Wednesday deposit points to the birth-date groups.
What SSI recipients see on Dec. 1
SSI is paid on the 1st, which falls on Tuesday, Dec. 1. Social Security describes the program as monthly payments to people with disabilities and older adults who have little or no income or resources, and the check runs on its own calendar even when a person also collects a Social Security benefit.
For people who get both, the two payments land two days apart in December: SSI on Tuesday the 1st and Social Security on Thursday the 3rd. Households that budget around one date should plan for the earlier deposit to cover the first days of the month.
- Dec. 1 (Tuesday): SSI for everyone who receives it
- Dec. 3 (Thursday): Social Security for people who started before May 1997 or also receive SSI
- Dec. 9 (second Wednesday): Social Security for birth dates 1 through 10
- Dec. 16 (third Wednesday): Social Security for birth dates 11 through 20
- Dec. 23 (fourth Wednesday): Social Security for birth dates 21 through 31
Does the 3.6% increase show up in these checks?
The cost-of-living adjustment is a 2027 change. In an Oct. 14 letter to advocates signed by Nick Perrine, the agency’s chief communications officer, Social Security announced that benefits will increase by 3.6 percent in 2027 for 76 million Americans on Social Security and SSI. The December deposits above are the last paid before that year begins.
The same letter says people who sign up for digital notices by Nov. 18 can see their personal increase online, up to three weeks earlier than the mailed notice. Mailed notices go out in December. Before then, the Wednesday paydays in November fall on Nov. 11, 18 and 25.
If a December deposit does not arrive
The schedule itself carries one instruction for a payment that has not shown up: allow three additional mailing days before contacting Social Security. People who changed banks or accounts this year can confirm where the money is going by signing in to my Social Security, which the agency says lets beneficiaries update direct deposit and print proof of benefits.
Looking ahead, the agency’s 2027 schedule lists the January Wednesday paydays as Jan. 13, 20 and 27 for the same three birth-date groups, so the pattern carries into the new year.
Counting on the Dec. 9, 16 or 23 deposit?
A December payment that lands a day or two late can leave a rent, heat or pharmacy bill hanging, and the schedule lists dates without saying what to do on the day after one passes. The dates are the same fixed ones every year, which makes a missed one easy to spot and easy to lose time over.
The Social Security Check Protection Kit includes the 2026 payment calendar and a first-24-hours plan for a late or missing payment, so the steps are written down before a deposit is overdue. It is a 75-page guide, and its Part 4, Late, Short or Wrong Payments, covers what to do when an amount does not arrive as expected.
