The 2026 Social Security cost of living adjustment takes effect with the December 2025 benefit, but because Social Security pays one month behind, the first payment showing the 2.8 percent increase arrives in January 2026. Supplemental Security Income recipients see the raise a day earlier, on December 31, 2025, because January 1 is a federal holiday. The Social Security Administration announced the 2.8 percent figure on October 24, 2025, and it applies to roughly 75 million people.
Why December Effective but January Paid
Federal law directs the Social Security Administration to increase your primary insurance amount each December to keep pace with rising prices.1eCFR. 20 CFR 404.270 – Cost-of-Living Increases The underlying statute, 42 U.S.C. § 415(i), sets out the formula.2Office of the Law Revision Counsel. 42 USC 415 – Computation of Primary Insurance Amount So the higher amount is technically effective for December 2025. But Social Security pays benefits in the month after they are earned, which is why the check reflecting the new COLA does not hit your account until January 2026.
When SSI Recipients Get the Increase
Supplemental Security Income follows a different schedule. SSI is paid on the first of each month. When the first falls on a weekend or federal holiday, the payment shifts to the last business day before. January 1, 2026 is New Year’s Day, so SSI recipients will receive their first COLA-adjusted payment on December 31, 2025.3Social Security Administration. Cost-of-Living Adjustment (COLA) Information
The 2026 federal SSI rate is $994 per month for an eligible individual and $1,491 for an eligible couple.4Social Security Administration. SSI Federal Payment Amounts for 2026 Some states add a supplement on top, so your total may be higher.
January 2026 Social Security Payment Dates
For retirement and disability beneficiaries, Social Security pays on a rotating Wednesday schedule tied to your date of birth. January 2026 is the first month reflecting the 2.8 percent increase:5Social Security Administration. Schedule of Social Security Benefit Payments 2026-2027
- Birth date 1st through 10th: Wednesday, January 14, 2026
- Birth date 11th through 20th: Wednesday, January 21, 2026
- Birth date 21st through 31st: Wednesday, January 28, 2026
The same rotation repeats every month. If a scheduled Wednesday lands on a federal holiday, the payment moves to the business day before.6Social Security Administration. Paying Monthly Benefits
If You Started Benefits Before May 1997 or Receive Both Social Security and SSI
The Wednesday rotation does not apply to you. Your Social Security payment arrives on the third of each month, and your SSI (if you get it) arrives on the first. When either date falls on a weekend or holiday, the payment moves to the preceding business day.6Social Security Administration. Paying Monthly Benefits January 3, 2026 is a Saturday, so those Social Security payments will land on Friday, January 2, 2026.
Why Your Actual Raise May Look Smaller
If you are enrolled in Medicare Part B, the premium is withheld from your Social Security check before it reaches you. The standard Part B premium for 2026 is $202.90 per month, up from $185.00 in 2025.7Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles That $17.90 monthly increase comes out of your COLA before you ever see it, so the net raise on your deposit will be less than 2.8 percent of your gross benefit.
A federal “hold harmless” provision at 42 U.S.C. § 1395r(f) keeps the Part B increase from exceeding the dollar amount of your COLA when the premium is deducted from your Social Security payment.8Office of the Law Revision Counsel. 42 USC 1395r – Amount of Premiums for Individuals Enrolled For most beneficiaries this means January’s net deposit will not fall below December’s. The protection does not apply if you are newly enrolled in Medicare, if a state Medicaid agency pays your premium, or if you pay the higher income-related premium (IRMAA).
How to See Your New Amount Before January
The Social Security Administration mails personalized COLA notices in December. Each notice shows your previous benefit next to the new amount, and if you have Medicare it reflects the updated Part B deduction.9Social Security Administration.
