Social Security’s Last December Payment Lands Wednesday, Dec. 23, Two Days Before Christmas, for Recipients Born on the 21st Through the 31st

For Social Security recipients whose birthdays fall late in the month, the December deposit cuts it close: it lands on Wednesday, Dec. 23, two days before Christmas. The date covers everyone on the birth-date schedule who was born on the 21st through the 31st, according to the Social Security Administration’s 2026 payment calendar. It is the last Wednesday payment of the year, and the last Social Security deposit of 2026 still figured before the 3.6% raise.

Two earlier Wednesdays carry the rest of the month’s birth-date payments. A separate set of deposits, already carrying the raise, arrives on Dec. 31, but those count as January payments sent early, so Dec. 23 closes out December’s payment cycle. For the late-birthday group, it is the only Social Security money due this month.

Three Wednesdays Carry December’s Birth-Date Payments

Most people who started benefits after April 1997 are paid on a Wednesday chosen by birth date. Under the agency’s payment-day regulation, people born on the 1st through the 10th are paid on the second Wednesday of the month, those born on the 11th through the 20th on the third Wednesday, and those born after the 20th on the fourth Wednesday.

December 2026 has five Wednesdays, on the 2nd, 9th, 16th, 23rd and 30th. That puts the three birth-date payments on Dec. 9, Dec. 16 and Dec. 23. Kiplinger’s 2026 payment schedule lists the same three dates.

The birthday that counts is the one belonging to the worker whose earnings record the benefit is paid on. The regulation assigns every beneficiary on one record the same payment day, so a spouse or child collecting on a worker’s record is paid on the worker’s Wednesday, not on a Wednesday tied to their own birth date.

Two other groups are paid earlier in the month and are not part of the Wednesday rotation: SSI recipients, whose December payment is due Tuesday, Dec. 1, and people paid on the 3rd, due Thursday, Dec. 3.

Why the 21st-to-31st Group Lands So Close to Christmas

The fourth Wednesday in December can fall anywhere from the 22nd to the 28th. This year it falls on the 23rd, two days ahead of Christmas Day, which federal law lists among the legal public holidays as Dec. 25. In 2026, Christmas lands on a Friday.

Because Dec. 23 is a regular business day, nothing moves. The holiday rule only shifts a payment when the scheduled date itself is a weekend or a federal holiday. The same group saw a near miss last month, when its November payment arrived on Nov. 25, the day before Thanksgiving.

Social Security’s rule for the Wednesday groups is narrow: if the scheduled Wednesday is itself a federal holiday, the money comes on the preceding day that isn’t one. That is what happened in November, when the first birth-date group’s payment moved up to Tuesday, Nov. 10 because Nov. 11 is Veterans Day. No December Wednesday is a holiday, so all three dates hold.

For the small number of beneficiaries still paid by paper check, the agency’s calendar asks people to allow three additional mailing days before contacting Social Security about a missing payment. Counted from Dec. 23, with Christmas Day closed to mail, that waiting period stretches past the holiday.

The Dec. 23 Deposit Is Still Figured at 2026 Rates

Social Security pays each month’s benefit in the month after it is due, according to the Social Security Handbook’s section on payment dates. The money that arrives on Dec. 23 is the November benefit, calculated at this year’s amount.

The 3.6% cost-of-living adjustment begins with payments in January 2027 for about 72 million Social Security beneficiaries, the agency said in its Oct. 14 announcement. Unless something else in a person’s record has changed, the Dec. 23 deposit should match the one that arrived in November.

The size of the coming increase shows up in the agency’s 2027 COLA fact sheet. The agency estimates the average check for all retired workers will climb from $2,095 to $2,170 a month once the raise takes hold, a gain of $75. The site covered the full set of figures when the 3.6% raise was announced.

A Five-Week Wait Until the Raise Arrives on Jan. 27

The late-birthday group’s first check with the higher amount is due on the fourth Wednesday of January. The agency’s 2027 schedule places that payment on Jan. 27, 2027.

That leaves 35 days between the Dec. 23 deposit and the next one. December’s payment has to cover holiday spending, the start of the new year and most of January’s bills before any of the raise shows up.

The gap is longer than usual because December’s fourth Wednesday falls early in its week range while January’s falls late. In a typical month the stretch between fourth-Wednesday payments is four or five weeks; this one sits at the long end.

People who want to see their exact 2027 amount before then can find their personal COLA notice online. The agency said beneficiaries who sign up for paperless notices in a my Social Security account by Nov. 18 can view the notice up to three weeks before the paper version arrives in December, a deadline the site detailed in its report on going paperless to see the 2027 COLA notice.

For people on Medicare, the agency said the 2027 premium amount will also appear in the online Message Center starting in late November. That figure matters for the late-birthday group in particular, since the Jan. 27 deposit will be the first one to reflect both the raise and any new premium.
