Every fall, one Social Security number grabs the headlines: the cost-of-living adjustment, or COLA (the yearly raise that keeps benefits roughly even with inflation). But the COLA is only one of several numbers that reset for 2027, and most of them are not official yet. This guide separates what is already locked into law from what is still an estimate, so you know which figures you can plan around today and which ones to wait on.
Updated October 14, 2026: the Social Security Administration has now published the official 2027 numbers - a 3.6% COLA, a $192,300 taxable wage base and new earnings-test limits - and every figure below has been updated to them. Only the Medicare Part B premium and deductible are still estimates; CMS sets those, normally in November. (When this guide first ran on August 10, the full retirement age was the only settled 2027 number.)
The one 2027 change that is already law: full retirement age hits 67
Full retirement age (FRA) is the age at which you can claim 100 percent of your Social Security benefit, with no early-claiming reduction and no delayed-retirement bonus. For everyone born in 1960 or later, that age is exactly 67. People born in 1960 turn 67 in 2027, so 2027 is the first year the age-67 FRA actually applies to anyone. This is fixed law, the final step of the increase written into the 1983 Social Security Amendments, which raised full retirement age from 65 to 67 across birth-year cohorts (with a plateau at 66 for people born 1943 to 1954). It is not an estimate and it will not change in October.
Why it matters in dollars: you can still claim as early as 62, but claiming before FRA permanently cuts your monthly check, and claiming after FRA (up to age 70) permanently raises it. For someone with a $2,000 FRA benefit, claiming at 62 drops it to about $1,400, while waiting until 70 lifts it to roughly $2,480. Same person, same work record, and the timing alone moves the check by more than $1,000 a month.
The 2027 COLA: officially 3.6 percent
The 2026 COLA was 2.8 percent. The 2027 COLA is 3.6 percent, announced by SSA on October 14, 2026, the morning the September inflation report completed the third-quarter Consumer Price Index data the formula uses. It is the largest COLA since 2023. It starts with benefits payable in January 2027 (December 31, 2026 for SSI).
SSA estimates the average retired worker’s benefit rises from $2,095 to $2,170 a month, about $75 more. For the exact CPI-W arithmetic, what September needed to print, and the net raise after Medicare, see our post on the official 2027 COLA.
Medicare Part B: the quiet bite out of your raise
Here is the part the COLA headline hides. If you are on Medicare, your Part B premium (the monthly cost for doctor visits and outpatient care) is deducted straight from your Social Security check. Part B premiums reset every fall too, and when they rise, they eat part of your COLA before it ever reaches your bank account.
The 2026 standard Part B premium is $202.90 a month, up from $185.00 in 2025, a $17.90 increase. The annual Part B deductible is $283. As of October 14, 2026 the 2027 premium has still not been announced - the Medicare Trustees project $209.50, and CMS normally sets the real figure in November - so any 2027 Part B number you see today is an estimate.
Worked example, using the 2026 actual numbers:
- The average retired worker’s benefit rose from $2,015 to $2,071 in January 2026, a $56 raise from the 2.8 percent COLA.
- The standard Part B premium rose $17.90 in the same window.
- Because Part B comes out of the check, about $17.90 of that $56 raise was absorbed by the premium. Net raise: roughly $38 a month.
That is not a reason to ignore the COLA. It is a reason to budget the net number, not the headline percentage.
The taxable maximum (wage base): what high earners owe
The taxable maximum, or wage base, is the ceiling on earnings subject to the 6.2 percent Social Security payroll tax. For 2026 it is $184,500, up from $176,100 in 2025. Earn above that and you pay no more Social Security tax on the extra dollars (Medicare tax, by contrast, has no cap). If you want the mechanics of the payroll taxes coming out of your paycheck, see our guide to what FICA is.
For a worker earning exactly the 2026 cap, the maximum Social Security tax is $184,500 times 6.2 percent, which comes to $11,439. For 2027 the wage base rises to $192,300, announced alongside the COLA, so the employee maximum becomes $11,922.60 - $483.60 more for anyone earning above the new cap. The 2026 Trustees Report had projected $190,200; the official figure came in higher.
Earnings-test limits: only if you work while collecting early
If you claim Social Security before FRA and keep working, the retirement earnings test can temporarily withhold part of your benefit. The limits for 2026, and the official 2027 limits SSA published on October 14, 2026:
- Under FRA for the whole year: you can earn $24,480 in 2026 ($2,040 a month), rising to $25,560 in 2027 ($2,130 a month), before $1 is withheld for every $2 you earn above the limit.
- In the year you reach FRA: a higher limit of $65,160 in 2026 ($5,430 a month), rising to $67,920 in 2027 ($5,660 a month); only $1 is withheld for every $3 over, and it counts only earnings before the month you reach FRA. From that month on, the test disappears entirely.
Important and widely misunderstood: withheld benefits are not lost. Once you reach FRA, Social Security recalculates your benefit and pays the withheld amount back over time.

What this means for your own plan
Social Security was never designed to be your whole retirement. It replaces only about 40 percent of pre-retirement income for an average earner. The COLA keeps it from losing ground to inflation, but Part B and payroll taxes quietly claw some of that back, which is exactly why your own savings do the heavy lifting.
To pressure-test your number, run your expected benefit and savings through our retirement calculator, then sanity-check the target against our guides on how much you need to retire and the 4 percent rule for how much you can safely withdraw each year.
FAQ
Is the 2027 COLA confirmed yet?
Yes. On October 14, 2026 the Social Security Administration confirmed a 3.6 percent COLA for 2027, starting with January 2027 benefits. For the average retired worker that is about $75 more a month before any change in the Medicare Part B premium.
Why did my Social Security raise feel smaller than the COLA?
Because your Medicare Part B premium is deducted from your check, and it usually rises at the same time. In 2026 the standard premium went up $17.90 a month, offsetting a chunk of the average $56 COLA raise. You feel the net amount, not the headline percentage.
What is fixed for 2027 no matter what?
Full retirement age. For anyone born in 1960 or later it is exactly 67, and 2027 is the first year that group reaches it. That is set by the 1983 law and will not change in the fall announcements.
Does working after I claim reduce my Social Security permanently?
Not permanently, when it is due to the earnings test. Before FRA, earning over the limit ($24,480 in 2026) temporarily withholds part of your benefit, but once you reach FRA the amount is recalculated and paid back. After FRA there is no earnings limit at all.
