Social Security COLA for 2027: What It Means for SSDI and SSI Checks

Social Security and Supplemental Security Income (SSI) payments go up 3.6 percent for 2027. The first higher SSI payment arrives December 31, 2026, and most people on SSDI see the raise in their January 2027 deposit. If Medicare Part B comes out of your check, the 2027 premium, not yet announced, is projected to take back a few dollars of it.

• The SSI federal payment standard rises to $1,029 a month for an individual and $1,544 for a couple.
• SSA estimates the average disabled worker's monthly benefit goes from $1,642 to $1,701.
• SSI's first higher payment lands on December 31, 2026. SSDI payments made on a Wednesday arrive January 13, 20 or 27, 2027, depending on a birth date.

What changes for SSDI and SSI in 2027

The Social Security Administration (SSA) announced the 3.6 percent COLA on October 14, 2026. By law, it follows the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), comparing the third quarter of 2026 with the third quarter of 2025. Nearly 72 million Social Security beneficiaries and about 7.3 million SSI recipients get it, and some people are in both groups.

The two programs feel the raise differently. SSDI goes up by 3.6 percent of your own benefit, so a $1,000 check grows by about $36 and a $2,000 check by about $72. SSI is built around a flat maximum, the federal payment standard. That maximum rises by the same $35 for every individual, and your actual SSI check is the maximum minus your countable income.

Amount	2026	2027
SSI federal payment standard, individual	$994 a month	$1,029 a month
SSI federal payment standard, couple	$1,491 a month	$1,544 a month
Average benefit, all disabled workers (SSA estimate)	$1,642	$1,701
Average benefit, disabled worker with spouse and children (SSA estimate)	$2,970	$3,077
Substantial gainful activity limit, non-blind	$1,690 a month	$1,770 a month
Substantial gainful activity limit, blind	$2,830 a month	$2,950 a month
Trial work period monthly earnings threshold	$1,210	$1,270
SSI resource limit, individual and couple	$2,000 and $3,000	$2,000 and $3,000

SSA's average-benefit figures compare January 2027 benefits before and after the COLA.

If you work while on SSDI, watch the substantial gainful activity (SGA) limit, the monthly earnings level SSA uses to judge whether you are working too much to qualify. SSI's resource limit is the one figure that doesn't move. For how your base benefit is figured in the first place, see How Much Does Social Security Disability Pay?

When the first higher payment arrives

COLAs take effect with benefits for December, and SSA pays December's benefits in January. So the raise shows up in the payment you get in January 2027, or for some people, on the last day of December 2026.

Your SSDI payment day is set by a federal regulation, 20 CFR 404.1807. If you applied after April 1997, it usually depends on the birthday of the worker whose record you are paid on. The main exceptions, paid on the 3rd, are people whose benefits trace to an application filed before May 1997 and people who also get SSI (a few smaller groups, such as people living abroad, are too). When a payment day falls on a weekend or federal holiday, SSA pays on the closest earlier business day.

Who	First payment with the 2027 COLA	Why that date
SSI recipients	Thursday, December 31, 2026	SSA's announced start for higher SSI payments
SSDI, worker born on the 1st to 10th	Wednesday, January 13, 2027	Second Wednesday of the month
SSDI, worker born on the 11th to 20th	Wednesday, January 20, 2027	Third Wednesday of the month
SSDI, worker born on the 21st to 31st	Wednesday, January 27, 2027	Fourth Wednesday of the month
SSDI paid on the 3rd (pre-May 1997 claim, or you also get SSI)	Thursday, December 31, 2026	January 3 is a Sunday and January 1 is New Year's Day

The December 31 SSI deposit is your January payment, sent early. It isn't a bonus. This is the date that catches people out: the money arrives in December, but it has to last through January.

## How the Medicare Part B premium takes a share

Most people who have both Social Security and Medicare Part B have the premium taken straight out of their monthly check. The 2026 standard premium is $202.90 a month.

The Centers for Medicare & Medicaid Services (CMS) had not published the 2027 premium as of November 3, 2026. The 2026 Medicare Trustees Report, released June 9, 2026, projects $209.50 a month, an increase of $6.60. That is a forecast, and the official figure can differ. SSA says your 2027 premium will show in your my Social Security Message Center starting in late November, and Medicare will post the 2027 numbers at medicare.gov.

The new premium and the COLA hit the same payment. Here is the math for the average disabled-worker benefit, if the projected premium holds:

	2026	2027 (projected premium)
Monthly benefit before Medicare	$1,642	$1,701
Standard Part B premium	$202.90	$209.50
What's left after the premium	$1,439.10	$1,491.50

The raise on paper is $59. After the premium, it's $52.40. If you pay an income-related surcharge on Part B, your numbers will differ.

The hold-harmless rule

Section 1839(f) of the Social Security Act keeps a Part B increase from shrinking your net Social Security check. It covers you if you were entitled to Social Security retirement, survivors or disability benefits for November and December 2026 and your Part B premium was deducted from those benefits for December 2026 and January 2027. For you, the premium can rise only as far as your benefit rose.

With a 3.6 percent COLA, that matters only for small checks. If the premium rises the projected $6.60, only benefits under about $184 a month would gain anything from it, since 3.6 percent of a larger check already covers the increase.

The Trustees say roughly 30 percent of Part B enrollees fall outside the rule: new enrollees, people who don't receive Social Security checks, higher-income people who pay the income-related adjustment, and people with both Medicare and Medicaid. For that last group, the state Medicaid program pays the premium, so the increase never touches their check.

If you get both SSI and Social Security

This is where the COLA surprises people. When your Social Security check goes up in January, SSA counts the extra dollars as income when it figures your January SSI payment (20 CFR 416.420). Because SSI is the payment standard minus countable income, part of your SSI raise disappears.

Say you get $500 a month from Social Security plus SSI. The COLA adds about $18 to the Social Security check. The federal SSI standard rises $35, from $994 to $1,029, but SSA subtracts the new $18 of income, so your SSI goes up only about $17. Put together, you come out about $35 a month ahead, the same as the federal SSI increase, before any state supplement.

People who get both are paid Social Security on the 3rd, and January 3, 2027 is a Sunday, so both of your January payments should arrive on December 31, 2026.

## State supplements change the SSI total

The federal SSI standard is the same everywhere, but many states add their own supplement, and SSA's COLA announcement doesn't tell you what your state will pay. Supplement amounts also depend on your income and living arrangement. SSA sorts the states into groups:

Group	Examples from SSA's list	Who to ask
No state supplement	Arizona, Arkansas, Mississippi, North Dakota, Tennessee, West Virginia, Northern Mariana Islands	No one; you get the federal amount only
SSA runs the supplement	California, Hawaii, Montana, Nevada, New Jersey, Vermont	SSA, which can give you your total
The state runs its own supplement	Alabama, Florida, Georgia, Illinois, New York, Texas	The state agency that pays it
Split between SSA and the state	Delaware, District of Columbia, Iowa, Michigan, Pennsylvania, Rhode Island	SSA for some categories, the state for others

So in California, SSA can tell you the combined 2027 amount. In New York or Texas, SSA says to contact the state for supplement payment information. Every other state falls into one of these groups too; SSA's Understanding SSI benefits page has the full list.

Your COLA notice and what to check

You don't apply for the COLA; automatic yearly adjustments began in 1975. What you do get is a notice with your new amount, and the fastest way to see it is online. Create a my Social Security account at ssa.gov/myaccount and sign up for paperless notices by November 18, 2026, and your notice appears in the Message Center starting in late November, up to three weeks before paper. You can turn on a text or email alert for it. Everyone else gets a paper notice in December.

For Social Security beneficiaries, the 2027 notice is a single page listing your new benefit, the payment dates and any deductions, such as the Medicare premium. Check that the gross amount is about 3.6 percent higher, that the Medicare deduction matches the 2027 premium, and, if you get SSI, that the amount reflects your current income and living situation. SSA's services are free, and it won't ask for fees by wire transfer or gift card.

When to talk to a lawyer

A lawyer can't make the COLA bigger. Help is worth it when the notice brings bad news or your claim is stuck, for example if:

• your notice says your SSI will drop or stop, and the reason doesn't match your situation;
• an overpayment notice arrives with, or soon after, your COLA notice;
• you are working on SSDI, your pay is near the 2027 SGA limit of $1,770 a month, and SSA starts asking about your work;
• your SSDI or SSI application or appeal is still pending. Our SSDI Back Pay Calculator gives a rough idea of what past-due benefits could add up to.

A notice that cuts or stops benefits explains how to appeal and by when, so write that date down the day you open it. You can find a Social Security disability lawyer near you in our directory.

Frequently asked questions

How much is the Social Security COLA for 2027?

The 2027 cost-of-living adjustment is 3.6 percent. SSA announced it on October 14, 2026, based on the rise in the CPI-W from the third quarter of 2025 to the third quarter of 2026. It applies to Social Security retirement, survivors and disability benefits and to SSI. The 2026 COLA was 2.8 percent, so this year's increase is larger.

When will I see the 2027 COLA in my SSDI check?

Most SSDI beneficiaries see it in their January 2027 payment: January 13 if the worker on the record was born on the 1st through 10th, January 20 for the 11th through 20th, and January 27 for the 21st through 31st. If you are paid on the 3rd, as people with pre-May 1997 claims or SSI are, it comes on December 31, 2026.

Is the December 31 SSI payment an extra check?

No. The SSI payment that arrives on December 31, 2026 is your January 2027 payment, sent early because January 1 is New Year's Day. It's the first payment at the 2027 rate, with a federal maximum of $1,029 for an individual. Because January's money has already arrived, budget that deposit to cover the whole month of January.

How much will the Medicare Part B premium be in 2027?

CMS had not announced the 2027 standard Part B premium as of November 3, 2026. The 2026 Medicare Trustees Report estimates $209.50 a month, up from $202.90 in 2026, though the final figure can differ. SSA says your 2027 premium will appear in your my Social Security Message Center starting in late November, and Medicare will post official 2027 amounts at medicare.gov.

Does the 2027 COLA change how much I can earn on SSDI?

The work limits change in January 2027 as part of SSA's yearly adjustments. The substantial gainful activity limit rises to $1,770 a month, or $2,950 if you are blind, and a month of earnings above $1,270 counts as a trial work month. Keep a simple record of what you earn each month so you can compare it with those limits.
