S-Corp Social Security Wage Base: The 2027 Jump to $192,300
The Social Security Administration raised the 2027 Social Security wage base to $192,300, up from $184,500 in 2026 — a $7,800 jump announced on October 14, 2026. That extra $7,800 of wages now falls inside the 6.2% OASDI tax instead of above it. If your reasonable compensation sits at or near the old cap, your S-corp’s payroll tax bill goes up on January 1, 2027, whether or not you change a single thing about how you pay yourself.
What Actually Changed in the Social Security Wage Base
The tax rate itself didn’t move. Employees and employers each still pay a combined 7.65% — 6.2% for Social Security (OASDI) and 1.45% for Medicare — and self-employed taxpayers still pay 15.30%, per the IRS’s Topic 751. What moved is the ceiling on the 6.2% piece. In 2026, OASDI tax applies only to the first $184,500 of wages. Starting with wages paid in 2027, that ceiling becomes $192,300. Medicare tax has no ceiling in either year — it applies to every dollar of wages, as it always has.
In dollar terms, the maximum OASDI tax an employee can owe rises from $11,439 in 2026 to $11,922.60 in 2027 — and your S-corp owes a matching $11,922.60 on the employer side for any shareholder-employee paid at or above the new cap, according to the SSA’s 2027 COLA fact sheet. The SSA announced this new Social Security wage base alongside a 3.6% cost-of-living adjustment to benefits for 2027 — the two numbers are announced together each year, but only the wage base affects your payroll tax bill as an employer.
Why the Wage Base Hits S-Corp Owners Twice
A W-2 employee at a normal company feels half of a wage-base increase directly, in a smaller paycheck, while the employer absorbs the other half as a cost of doing business. As an S-corp shareholder-employee, you’re effectively on both sides of that transaction — the employer share comes out of the same corporation whose profit ultimately flows to you on your K-1. A $7,800 increase in the wage base costs roughly $967.20 in combined OASDI tax ($483.60 on the employee side, $483.60 on the employer side) for any owner whose reasonable salary is at or above $192,300 for the full year. Below that level, the cost is smaller and scales with how much of the $7,800 band your salary actually covers.
Where This Lands in Your Reasonable Salary Range
If you’ve set your salary near the wage base as part of a deliberate FICA strategy — paying yourself up to the cap and taking the rest as distributions — the cap just moved out from under you. The $7,800 band between $184,500 and $192,300 is now taxable OASDI wages in 2027 even if your salary number doesn’t change at all. This is a good trigger to revisit your reasonable compensation analysis for the year ahead rather than carrying the same number forward out of habit — see our guide on how much your S-corp should pay you for the factors the IRS actually looks at.
One thing that doesn’t change: if your reasonable salary already exceeds $192,300, the wage base increase costs you nothing further. OASDI tax is capped at the new ceiling either way — the owners who feel this increase are the ones whose pay sits inside the new $7,800 band, not above it.
Don’t Confuse This With the Additional Medicare Tax Threshold
The $192,300 figure is a Social Security number, and it’s indexed to national average wage growth. The Additional Medicare Tax threshold is a different number entirely, and it hasn’t moved since it took effect in 2013: employers must withhold an extra 0.9% on wages above $200,000 in a calendar year, regardless of the employee’s filing status, per IRS Topic 751. That $200,000 trigger is fixed by statute — it isn’t adjusted for inflation the way the OASDI wage base is, so it will keep catching more owners every year the wage base rises toward it. We cover the mechanics of that surtax, including the married-filing-jointly threshold, in our S-corp Additional Medicare Tax guide.
What to Do Before January 1
Confirm your payroll provider has loaded the 2027 tables. Most major payroll services update automatically, but if you run payroll in-house or through a bookkeeper using last year’s spreadsheet, the $192,300 cap needs to be entered manually before the first 2027 pay run. An employer that keeps withholding OASDI tax using the old $184,500 cutoff simply undercollects and has to true it up later, which is a worse conversation than fixing it now.
Revisit the salary number itself, not just the withholding table. Year-end is when most S-corp owners already sit down with their CPA to true up officer compensation for the current year and set the number for next year. Treat the wage base change as one more input into that conversation, alongside any change in duties, hours, or profitability — not as a reason by itself to raise or lower what you pay yourself.
Run the new number against your 2027 cash flow projection. If your reasonable salary falls inside the $184,500–$192,300 band, the extra employer-side OASDI tax is a real, predictable cost — not a rounding error — and it’s easiest to plan for before the year starts rather than noticing it in a February payroll report. For most single-shareholder S-corps the number is small enough to absorb without changing the compensation strategy, but it’s worth seeing in writing rather than assuming.
The Real Complexity
None of this changes the underlying rule: reasonable compensation has to reflect what you’d pay an unrelated person to do your job, not the number that minimizes payroll tax. A rising cap is a reason to revisit the number, not a reason to chase it, and the IRS has never treated “I kept my salary under the cap” as a defense on its own. If you’re not sure where your 2027 salary should land once the new ceiling, your distribution mix, and your actual role in the business are all accounted for, that’s a conversation worth having before your first 2027 paycheck runs, not after.
