Social Security COLA 2027: The 3.6% Raise & Your Check

Short answer: Social Security benefits are rising 3.6% for 2027. The increase applies to December 2026 benefits, so most people see it in the January 2027 payment. SSI recipients see it in the payment dated December 31, 2026. The Social Security Administration (SSA) estimates the average retired worker’s check will go from $2,095 to $2,170 a month, which works out to about $75 more a month, or roughly $900 over a year. It’s the largest COLA since the 8.7% increase paid in 2023. Your actual take-home raise depends on three things: what Medicare Part B deducts in 2027, whether more of your benefit becomes taxable, and, if you’re under full retirement age and still working, the earnings test.

This guide covers what’s changing for 2027, how the 3.6% was calculated, what it means in dollars, the Medicare and tax side effects most headlines skip, and when your new amount shows up. It’s general education, not personalized financial or tax advice, and your own SSA notice is the final word on your benefit.

What’s changing for 2027 at a glance

All figures below come from SSA’s October 14, 2026 announcement, its 2027 COLA fact sheet and the Federal Register notice published on October 26, 2026.

Work credits

Earnings needed for one quarter of coverage: $1,890 → $1,970

How the 3.6% was calculated

The COLA isn’t a vote or a negotiation. It’s a formula set in law, and SSA has used the same method since 1983. SSA compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published by the Bureau of Labor Statistics, for July, August and September of this year with the same three months of last year.

Here’s the 2027 math from SSA’s COLA calculation page:

Q3 2025 CPI-W: 316.349 (July), 317.306 (August), 318.139 (September), for an average of 317.265
Q3 2026 CPI-W: 327.104 (July), 328.481 (August), 330.654 (September), for an average of 328.746
Increase: (328.746 − 317.265) ÷ 317.265 = 3.6%, rounded to the nearest tenth of a percent

Three details are worth knowing:

No inflation, no COLA. If the CPI-W average doesn’t rise, there’s no increase that year. Benefits don’t go down, though.
CPI-W is a worker index. It tracks prices paid by urban wage earners and clerical workers, not retirees specifically. The Federal Register notice points out that other price indexes exist, but CPI-W has been used by precedent since automatic COLAs began in 1975. Retirees who spend more on health care and housing sometimes find their personal inflation rate runs higher or lower than the COLA.
It’s a lagging catch-up. The 3.6% reflects price increases that already happened between mid-2025 and mid-2026. It restores purchasing power you’ve already lost. It doesn’t pre-fund next year’s price rises.

What the 3.6% means for your check

The quickest estimate: multiply your current gross monthly benefit (before Medicare or tax withholding) by 1.036. That’s about $36 more a month for every $1,000 of benefits. SSA rounds the result, so your notice may differ by a dollar or so.

Using SSA’s own averages:

Average retired worker: $2,095 → $2,170, or +$75 a month (about +$900 a year)
Aged couple, both receiving: $3,238 → $3,355, or +$117 a month (about +$1,404 a year)
Aged widow(er): $1,936 → $2,005, or +$69 a month
Disabled worker: $1,642 → $1,701, or +$59 a month
SSI individual (federal amount): $994 → $1,029, or +$35 a month

Two groups are worth calling out:

You haven’t claimed yet. If you turned 62 in 2026 or earlier, COLAs are already being applied to your benefit amount even if you haven’t started collecting. You don’t lose the 3.6% by waiting. Delayed retirement credits for claiming after full retirement age are separate and stack on top. Our guide to Social Security’s full retirement age explains how the claiming age changes your monthly amount.
You first become eligible in 2027. If you turn 62 in 2027, the 3.6% doesn’t apply to you. Your starting benefit is figured with the 2027 benefit formula, which is indexed to national wage growth instead. The Federal Register notice puts the 2025 national average wage index at $72,800.33, about 4.23% above 2024.

Medicare Part B: the deduction that eats part of the raise

If you’re on Medicare and your Part B premium comes out of your Social Security check, your take-home raise is the COLA minus any Part B increase.

What we know as of November 6, 2026:

2026 standard Part B premium: $202.90 a month, up from $185.00 in 2025. The 2026 deductible is $283 (CMS)
2027 standard Part B premium: not announced yet. CMS usually publishes it in the fall, and SSA says your 2027 premium will appear in your my Social Security Message Center in late November
Estimate only: the 2026 Medicare Trustees Report estimated the 2027 standard premium at $209.50, which would be $6.60 more than 2026. Treat it as a projection until CMS confirms the real number

Illustration (average retiree, using the Trustees’ estimate):

2026: $2,095 gross − $202.90 Part B = $1,892.10 deposited
2027: $2,170 gross − $209.50 Part B = $1,960.50 deposited
Take-home raise: about $68 a month instead of $75

The hold-harmless rule. A provision in the law stops a Part B increase from shrinking your Social Security check from one year to the next. Your Part B increase can’t be larger than your COLA in dollars. You’re generally protected if you received Social Security benefits for November and December and had Part B deducted for December and January. According to SSA, the rule does not apply if you:

Are enrolling in Part B for the first time
Pay an income-related monthly adjustment amount (IRMAA)
Have your premium paid by a state Medicaid agency

With a 3.6% COLA, only very small benefits are likely to hit this cap. Using the $6.60 estimate, it would take a gross benefit under roughly $183 a month (since $183 × 3.6% ≈ $6.60).

Higher earners: watch IRMAA. For 2026, IRMAA surcharges start above $109,000 of modified adjusted gross income for single filers and $218,000 for joint filers, based on your tax return from two years earlier. CMS says about 8% of Part B enrollees pay it. If you built up a health savings account before Medicare, the balance can pay Part B premiums tax-free. Medigap premiums don’t qualify. See our HSA vs FSA guide and HSA contribution limits. A Roth conversion or large capital gain can push you over a bracket two years later, so it’s worth checking before you act. See our guides to Roth IRA vs Traditional IRA and 2026 capital gains tax brackets.

A pie with one slice cut out, illustrating how the Medicare Part B premium takes part of the Social Security COLA — Part B comes out first. Your real raise is the COLA minus any premium increase.

Will the COLA make more of your benefit taxable?

It can. The federal test for taxing Social Security uses “provisional income”: half of your benefits plus your other income, including tax-exempt interest. Those thresholds are fixed in law and have never been adjusted for inflation. Each COLA therefore pulls a bit more benefit income over the line (IRS Topic 423; IRS Publication 915).

The thresholds

Single, head of household or qualifying surviving spouse: up to 50% of benefits may be taxable above $25,000 of provisional income, and up to 85% above $34,000
Married filing jointly: up to 50% above $32,000, and up to 85% above $44,000
Married filing separately and living with your spouse at any time during the year: the base amount is $0

Example: a single retiree whose other income stays the same

2026: $2,095 × 12 = $25,140 of benefits. Half is $12,570. Add $15,000 of pension and IRA income, and provisional income is $27,570
Taxable benefits in 2026: half of ($27,570 − $25,000) = $1,285
2027: $2,170 × 12 = $26,040 of benefits. Half is $13,020. Provisional income is $28,020
Taxable benefits in 2027: half of ($28,020 − $25,000) = $1,510
Result: the COLA alone adds $225 of taxable income, even though nothing else changed

This rule of thumb works only in the 50% band (provisional income between $25,000 and $34,000 for single filers). Above that, use Worksheet 1 in Publication 915 or tax software. The Congressional Research Service notes that the Congressional Budget Office estimates about 48% of beneficiaries will pay income tax on their benefits in 2026 (CRS IF11397).

Three practical tools:

Voluntary withholding. File Form W-4V with SSA to have 7%, 10%, 12% or 22% of each payment withheld for federal tax. No other percentages are allowed. It can save you from a surprise bill or estimated payments
The senior deduction. For tax years 2025 through 2028, people age 65 and older can claim an extra $6,000 deduction ($12,000 for a married couple if both qualify). It phases out above $75,000 of modified AGI ($150,000 for joint filers), and you can take it whether or not you itemize (IRS). It doesn’t change the formula that decides how much of your benefit is taxable. It lowers your taxable income afterward
Form SSA-1099. SSA mails it by early February. Box 5 is the number you need for your return

State taxes are separate, and most states don’t tax Social Security. Check your state’s revenue department. If you’re juggling IRA withdrawals as well, our required minimum distributions guide shows how RMDs feed into provisional income.

Working while collecting: the 2027 earnings test and payroll tax

If you claim before full retirement age and keep working, SSA temporarily withholds benefits once your earnings pass a limit. Both limits rise for 2027:

Under full retirement age for all of 2027: $1 withheld for every $2 earned above $25,560
The year you reach full retirement age: $1 withheld for every $3 earned above $67,920, counting only earnings in the months before your full-retirement-age month
From the month you reach full retirement age: no limit at all

Examples (illustrative):

Age 64 all year, earning $35,560 in wages: that’s $10,000 over the limit, so about $5,000 of benefits would be withheld for the year
Reaching full retirement age in October 2027, earning $77,920 from January through September: that’s $10,000 over the limit, so about $3,333 would be withheld

Withheld benefits aren’t simply lost. Once you reach full retirement age, SSA recalculates your monthly benefit to credit the months it withheld. It’s still a cash-flow hit while you’re working, though, so plan for it.

Payroll tax for higher earners. The Social Security portion of payroll tax (6.2% for employees, 12.4% if you’re self-employed) applies to earnings up to $192,300 in 2027, up from $184,500. If you earn at least that much, you’ll pay up to $483.60 more as an employee ($967.20 if self-employed). The 1.45% Medicare tax has no cap, and an extra 0.9% applies above $200,000 (single) or $250,000 (joint).

How 3.6% compares with past COLAs

SSA’s COLA history labels each increase by the December it took effect. The list below uses the year most people see it, which is the January payment year:

January 2022: 5.9%
January 2023: 8.7%, the largest since the early 1980s
January 2024: 3.2%
January 2025: 2.5%
January 2026: 2.8%
January 2027: 3.6%

A few reference points:

The 10 COLAs paid from 2018 through 2027 average about 3.4%, so 3.6% is a little above the recent norm
There was no COLA in 2010, 2011 or 2016, because CPI-W didn’t rise
The record is 14.3%, paid in 1980
The last time the COLA was exactly 3.6% was the increase paid in January 2012

When you’ll see your new amount

Your COLA notice

SSA posts notices online in late November in your my Social Security account Message Center
To get it online instead of by mail, create an account and set your notice preferences by November 18, 2026
Otherwise, your notice arrives by mail in December. SSA has switched to a simplified one-page notice
Your 2027 Medicare premium will also appear in the Message Center in late November

Your first payment with the 3.6% increase (SSA 2027 payment schedule)

SSI recipients: Thursday, December 31, 2026, because January 1 is a federal holiday
Paid on the 3rd of the month (you started benefits before May 1997, or you get both Social Security and SSI): Thursday, December 31, 2026, because January 3, 2027 is a Sunday
Birthday on the 1st–10th: Wednesday, January 13, 2027
Birthday on the 11th–20th: Wednesday, January 20, 2027
Birthday on the 21st–31st: Wednesday, January 27, 2027

The December 31 deposit is January’s payment arriving early, not an extra one. SSI recipients won’t get a second check in January. If a payment doesn’t arrive when expected, SSA asks you to allow three additional mailing days before contacting them.

What to do with your raise

A COLA isn’t really a raise in the “more spending money” sense. It’s a reset to cover prices that have already gone up. A few practical moves:

Update your budget in January, not now. Use your notice’s net amount, after Medicare and withholding, not the 3.6% headline. If you don’t track spending yet, our case for using an expense tracker is a good start
Compare it with your own inflation. If your rent, insurance or medical costs rose faster than 3.6%, the COLA won’t fully close the gap. Our U.S. inflation calculator shows how much buying power a fixed dollar amount loses over time
Re-check your withdrawal plan. A higher guaranteed income floor means you may need slightly less from savings. Our look at whether the 4% rule is still enough and the asset allocation by age guide can help you decide. To test the numbers, try the 4% rule calculator or walk through our can I retire with $3 million case study
Top up your cash buffer. Retirees still need an emergency reserve for big, irregular bills. See how much emergency cash a retiree should keep, or size it with the emergency fund calculator
Review tax withholding. If the example above looks like you, consider a W-4V before tax season, or adjust your estimated payments
Still a few years out? The COLA protects benefits you’ve already earned, but it doesn’t replace savings. See how to retire at 60 and our 401(k) vs IRA guide for where to put your next dollar. Our personal finance checklist puts the steps in order

Frequently asked questions

What is the Social Security COLA for 2027?

It’s 3.6%. SSA announced it on October 14, 2026. It applies to December 2026 benefits, so most beneficiaries see it in their January 2027 payment, and SSI recipients see it in the payment dated December 31, 2026.

How much will my Social Security check go up in 2027?

Multiply your current gross benefit by 1.036, which works out to about $36 more for every $1,000. SSA estimates the average retired worker goes from $2,095 to $2,170 a month (+$75). Your exact figure is on your COLA notice, available online in late November or by mail in December.

When does the 2027 COLA start?

It starts with the January 2027 payment, which arrives on January 13, 20 or 27 depending on your birth date. People paid on the 3rd of the month and SSI recipients get the increased payment on December 31, 2026.

Will Medicare Part B take my whole COLA?

For most people, no. The 2027 Part B premium hadn’t been announced as of November 6, 2026. The Trustees estimated $209.50, which would be $6.60 more than 2026’s $202.90. The hold-harmless rule also stops a Part B increase from lowering your net check, though it doesn’t cover new enrollees, IRMAA payers or people whose state Medicaid agency pays the premium.

Is the 2027 COLA bigger than 2026’s?

Yes. The January 2026 increase was 2.8%. The 3.6% for 2027 is the largest since the 8.7% increase paid in January 2023.

Do I get the COLA if I haven’t started collecting Social Security?

Yes, if you turned 62 in 2026 or earlier. COLAs are applied to your benefit amount from the year you turn 62, whether or not you’ve claimed. If you first become eligible in 2027, the 3.6% doesn’t apply to you, and your starting benefit uses the 2027 formula.

Does the COLA make my Social Security benefits taxable?

It can push some people over the line. The federal thresholds ($25,000 single, $32,000 joint, based on provisional income) aren’t indexed for inflation, so a larger benefit can raise the taxable portion even if your other income doesn’t change. The senior deduction ($6,000 per person age 65 or older, 2025–2028, with income limits) can lower your tax bill but doesn’t change that formula.

How is the Social Security COLA calculated?

SSA compares the average CPI-W for July through September of the current year with the same quarter a year earlier. For 2027, that was 328.746 against 317.265, an increase of 3.6% rounded to the nearest tenth. If the index doesn’t rise, there’s no COLA, but benefits never go down.

Bottom line

The 3.6% COLA adds about $75 a month to the average retiree’s check from January 2027 and is the biggest bump in four years. Before you plan around the headline number, wait for your notice and check three things: your 2027 Part B deduction, whether more of your benefit becomes taxable, and the earnings test if you’re working before full retirement age. Then update your budget and withdrawal plan with the net figure.
