Solo Biz Soft Editorial Team Searches for the Social Security benefit increase spike every October, right before the official announcement — and this year it matters a bit more if you’re self-employed. You don’t have an employer-sponsored pension cushioning you against inflation, and you’re the one funding the full Social Security tax rate yourself, not splitting it with an employer. Here’s what’s projected, what’s officially confirmed, and when the real numbers land.
What’s actually being projected
The cost-of-living adjustment (COLA) is calculated by comparing inflation data (specifically the CPI-W) for the third quarter of this year against the third quarter of last year. Since the full September data wasn’t available until early October, nobody has an official number yet — what’s circulating right now are projections from various retirement-policy analysts and organizations, currently clustering somewhere between roughly 3.5% and 4.7%—two of the most closely-watched independent forecasters converged on 3.5% as of late September, while other estimates run as high as 4.7%. The Social Security Administration is expected to confirm the real figure around October 14, 2026.
The other number that matters more for the self-employed: the wage base
COLA gets the headlines, but the Social Security wage base — the amount of income subject to the 12.4% OASDI portion of Social Security tax — is the number that directly hits your tax bill if your income is above it. For 2026 it’s $184,500. The Social Security Trustees Report projects it will rise to roughly $190,200 for 2027, though like the COLA, this won’t be officially confirmed until the same mid-October announcement. If your self-employment income runs above the cap, this projected increase means a bit more of your income will be subject to the OASDI portion of self-employment tax next year.
Why this hits differently when you’re self-employed
As an employee, Social Security tax is split 6.2% from you and 6.2% from your employer. As a self-employed person, you’re on the hook for the full 12.4% yourself (as part of the 15.3% total self-employment tax), up to the wage base. That also means a benefit increase is something you’re funding entirely out of your own pocket today in exchange for a larger check decades from now — worth remembering when you’re deciding how much to set aside for retirement separately, since Social Security alone was never designed to fully replace a working income.
What to actually do about it
Nothing requires action before the official announcement, but it’s a good prompt to check two things. Once the real 2027 figures land, re-run your numbers in the self-employment tax calculator if your income is near the wage base cap. And if you haven’t set up your own retirement savings — since there’s no employer plan doing it for you — compare your options with the solo 401(k) vs SEP IRA calculator. Social Security also just renamed its claiming ages around the same time — see what the Claiming Age Clarity Act changes.
Frequently asked questions
When will the official 2027 COLA be announced?
The Social Security Administration typically announces it in mid-October each year, once third-quarter inflation data is finalized — expected around October 14, 2026 for the 2027 adjustment.
Is the 2027 COLA already decided?
No. As of this writing, only projections exist, ranging roughly from 3.8% to above 4.7% depending on the source. The real number depends on September 2026 inflation data.
Does a higher wage base affect everyone who's self-employed?
Only if your net self-employment income is near or above the current cap ($184,500 for 2026). Below that threshold, the wage base change doesn’t affect your Social Security tax at all.
