Social Security COLA 2027: What the 3.6% Raise Means for Your Taxes
The Social Security Administration announced on October 14, 2026 that benefits will rise 3.6% in 2027, up from 2.8% this year. For a typical retired worker that is roughly $75 more a month starting in January. It is welcome news, but a bigger check also has tax consequences that most retirees never see coming, and a few changes on the worker side too.
The short version: Benefits rise 3.6% starting with the January 2027 payment (SSI recipients get it December 31, 2026). Up to 85% of Social Security can be federally taxable, and the income thresholds that trigger that tax have never been raised for inflation, so each COLA pulls more retirees in. New York State and New York City do not tax Social Security at all. Workers and self-employed people will pay Social Security tax on earnings up to $192,300 in 2027, up from $184,500.
What changes in 2027
| 2026 | 2027 | |
|---|---|---|
| Cost-of-living adjustment | 2.8% | 3.6% |
| Maximum earnings subject to Social Security tax | $184,500 | $192,300 |
| Medicare Part B standard premium | $202.90 a month | Set by CMS in November |
| New York State and NYC tax on benefits | None | None |
The Medicare Part B premium for 2027 is not official yet. The Medicare trustees projected an increase, and because Part B is usually deducted straight from your Social Security check, part of your raise will go to Medicare before you ever see it.
Will more of your Social Security be taxed?
Possibly, and this is the part that surprises people. Whether your benefits are federally taxable depends on your provisional income: your adjusted gross income, plus any tax-exempt interest, plus half of your Social Security.
| Filing status | Up to 50% of benefits taxable | Up to 85% of benefits taxable |
|---|---|---|
| Single | Provisional income over $25,000 | Over $34,000 |
| Married filing jointly | Over $32,000 | Over $44,000 |
Those thresholds were set in 1983 and 1993 and are not adjusted for inflation. Benefits are. So every COLA nudges provisional income higher while the line stays put. A retiree who sat just under $25,000 in 2026 can cross it in 2027 with no change in lifestyle at all. Nobody pays tax on more than 85% of their benefits, but crossing a threshold can still add real money to your federal bill.
The new senior deduction helps
The 2025 tax law added a $6,000 deduction for each person 65 or older for tax years 2025 through 2028, so a married couple who are both 65 or older can deduct $12,000. It is in addition to the standard deduction and the existing extra standard deduction for age, and you claim it whether or not you itemize.
It phases out at 6% of modified AGI above $75,000 for single filers and $150,000 for joint filers. It does not exempt Social Security from tax, as some headlines suggested, but for many middle-income retirees it cancels out most or all of the tax on their benefits.
New York does not tax Social Security
If you live in Westchester, the Bronx or anywhere else in New York State, your Social Security benefits are fully exempt from New York State and New York City income tax, no matter how much you receive. New York also lets people 59 and a half and older exclude up to $20,000 a year of pension and annuity income, including IRA distributions, from state tax.
That combination makes New York friendlier to retirees than its reputation suggests. Your federal return is where the planning happens.
If you are still working
The higher wage base of $192,300 means anyone earning above $184,500 will pay Social Security tax on more of their pay in 2027:
- Employees pay 6.2% on the extra $7,800, up to $483.60 more for the year.
- Self-employed people pay the full 12.4% on it, up to $967.20 more.
Medicare tax has no cap and does not change. If you are self-employed and near the cap, factor this into your 2027 quarterly estimates.
Five moves to make before December 31
- Check your withholding on benefits. Form W-4V lets you have 7%, 10%, 12% or 22% of your Social Security withheld for federal tax. If you owed in April, raise it now so 2027 does not repeat the surprise.
- Time your IRA withdrawals. Pulling extra from an IRA in December raises provisional income, which can make more of your Social Security taxable. Sometimes it makes sense to split a large withdrawal across two tax years.
- Take your required minimum distribution. If you are subject to RMDs, the penalty for missing one is steep. Take it by December 31.
- Give from your IRA if you give to charity. Once you are 70 and a half, a qualified charitable distribution sent directly from your IRA to a charity counts toward your RMD and stays out of your income, which keeps provisional income lower.
- Look at the senior deduction phase-out. If your income sits near $75,000 single or $150,000 joint, a small change in when you take income can protect the full $6,000.
Get the numbers right before you file
Retiree returns look simple and rarely are: Social Security, pensions, RMDs, Medicare premiums, the new senior deduction and New York's pension exclusion all interact. A small timing decision in December can change how much of your benefits are taxed in April.

Frequently asked questions
How much is the Social Security COLA for 2027?
3.6%, announced by the Social Security Administration on October 14, 2026. It starts with benefits paid in January 2027. SSI recipients get the increase in the payment made December 31, 2026.
Will the 2027 COLA make my Social Security taxable?
It can. Federal tax on benefits depends on provisional income (AGI plus tax-exempt interest plus half your benefits), and the $25,000 single and $32,000 joint thresholds are not adjusted for inflation. A raise in benefits can push you over a threshold even if nothing else changes.
