Why Did I Get Two Social Security Checks in December?
Surprised to see two Social Security deposits in December? Nothing went wrong. The second one is January’s payment, arriving early. January 1 is a federal holiday, so SSA pays it on the last business day of December: Thursday, December 31. The trap: spend it over the holidays and January arrives empty.
Who gets two, who gets one
| I am… | December | January | February |
|---|---|---|---|
| On SSI | Dec 1 + Dec 31 | nothing | Feb 1 |
| Paid on the 3rd (started before May 1997, or Social Security plus SSI) | Dec 3 + Dec 31 | nothing | Feb 3 |
| Born 1st–10th | Dec 9 | Jan 13 | Feb 10 |
| Born 11th–20th | Dec 16 | Jan 20 | Feb 17 |
| Born 21st–31st | Dec 23 | Jan 27 | Feb 24 |
Get both Social Security on the 3rd and SSI? That’s four deposits in December and none in January. Spousal and survivor benefits follow the worker’s birthday. Source: SSA calendars for 2026 and 2027; your own dates are in the payment date calculator.
Why December 31
SSA’s rule: a payment due on “a Saturday, Sunday or legal public holiday” is paid “the business day before” (SSA FAQ). January 2027 starts with three of those in a row (Friday the 1st is New Year’s Day, then the weekend), so the SSI payment due January 1 and the Social Security payment due January 3 both land on Thursday, December 31.
SSI gets this every year. The 3rd-of-month group only gets it when January 3 is a Sunday, which is why some years you see it and some years you don’t.
Three things that change with this payment
1. It’s probably your first 2027 raise. The 2027 COLA is announced in mid-October and applies to January benefits. Last year SSA said it outright: “Increased SSI payments will begin with the December 31, 2025 payment” (SSA 2026 fact sheet). The 2026 raise of 2.8% moved the SSI rate from $967 to $994 for one person. We post the 2027 numbers the day they’re released.
2. The new Medicare premium starts coming out. The 2027 Part B premium is deducted from the January payment on; it was $202.90 a month in 2026 (CMS). Your deposit changes by the raise minus the premium increase, so January can look smaller than December even in a raise year. SSA’s December COLA letter shows both numbers.
3. It’s 2026 income. Your SSA-1099 counts benefits paid in the calendar year, so people paid on the 3rd get 13 payments on their 2026 form. Social Security becomes taxable above combined income of $25,000 (single) or $32,000 (joint), per SSA’s tax page. Near a threshold? Tell whoever does your taxes. SSI is never taxed.
Tips people ask for next
Make it last 32–34 days. Move the December 31 deposit to savings the day it lands; move it back January 1. Next payday is February 1 (SSI) or February 3 (3rd).
Money showed up December 29? Some banks post federal deposits a day or two early. That’s the bank, not SSA. The official date is still the 31st.
Check your dates without calling. A my Social Security account shows every scheduled and past payment (SSA payment schedule page). SSA’s two-minute video:
A caller wants your bank details “for the double payment.” Hang up. SSA never calls, emails or texts to ask for your account, your Social Security number or a fee. The early payment is public and needs nothing from you. December is peak season for these calls; SSA’s own video shows the tells:
Direct Express card? Same dates. Representative payee? Record the December 31 deposit as January.
Nothing by December 31? Check again in the afternoon, allow three mailing days, then call 1-800-772-1213. Offices are closed December 25 and January 1.
One thing to do today
Find your row in the table and label the December 31 deposit “January.” That’s all it takes.
Next: every January 2027 payment date and the full 2027 SSI schedule, including the two other months next year with two SSI deposits.
Questions people ask about this
Is the December 31 payment extra money?
No. It is your January 2027 payment, one day early. January 1 is a federal holiday, so SSA pays the business day before. Nothing new arrives in January.
Do I have to pay it back?
No. A payment is returned only if the beneficiary died in the month it covers.
Does it count as 2026 income for taxes?
Yes. Your SSA-1099 lists benefits paid in the calendar year, so people paid on the 3rd will see 13 payments for 2026. SSI is not taxable.
Why is my January check smaller than December's?
The 2027 Medicare Part B premium starts coming out of the January payment. If the premium rose more than your COLA raise, the deposit shrinks.
When does this happen again?
For SSI, every January. In 2027, SSI also comes early on April 30 (for May) and July 30 (for August). December 2027 pays January 2028 early too, because January 1, 2028 is a Saturday.
