Does an S-Corp still save money above the Social Security wage base?

Usually less than you were told. An S-Corp saves payroll tax only on profit you take as distributions. Once your salary reaches the Social Security wage base, $184,500 for 2026, the 12.4% Social Security tax is already capped, so the savings shrink to Medicare tax. After $3,000 to $6,000 a year in costs, the net is often a few thousand dollars or less.

Who is this for?

This guide is for anyone who works for clients as a business and earns well into six figures: freelancers, 1099 contractors, independent contractors, sole proprietors and single-member LLC owners. It matters most for fractional executives, senior consultants, physicians and other professionals whose profit sits above roughly $200,000. Few self-employed professionals are in an S-Corp at all. About 1 in 20 Sumly users has made the election; most run as a sole proprietor or LLC.

Why do people say an S-Corp saves 15.3%?

As a sole proprietor or single-member LLC, you pay self-employment tax on your profit. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare, figured on 92.35% of your net earnings.

In an S-Corp, you pay yourself a salary through payroll, and payroll tax applies to that salary. The rest of the profit comes out as distributions, which carry no Social Security or Medicare tax. The pitch you hear is that every dollar moved from salary to distributions saves 15.3%. That is true only while your salary is below the Social Security wage base.

What is the Social Security wage base?

The Social Security wage base is the most income the 12.4% Social Security tax applies to each year. For 2026 it is $184,500. The Social Security Administration has announced $192,300 for 2027. Above it, you pay only Medicare tax.

The cap works the same way whether you are a sole proprietor or an S-Corp owner. So if your S-Corp salary is already at or above the wage base, you were never going to pay Social Security tax on your distributions anyway. The only payroll tax an S-Corp can save you is Medicare:

• 2.9% on the profit you take as distributions instead of salary.
• 0.9% Additional Medicare Tax on self-employment income above $200,000 (single) or $250,000 (married filing jointly), which distributions also avoid.

How much does an S-Corp save at $150K, $250K and $400K of profit?

Here are three self-employed professionals, each single, each paying a salary that rises with their profit. The table compares only Social Security and Medicare tax, which is where the S-Corp savings come from.

The savings go down as profit goes up. At $400,000, the sole proprietor already pays Social Security tax only up to the $184,500 cap, and so does the S-Corp owner on a $200,000 salary. The whole $6,437 is Medicare: 2.9% on the $169,400 gap between taxable self-employment earnings and salary, which is $4,913, plus the 0.9% Additional Medicare Tax the sole proprietor owes above $200,000, which is $1,525.

How the numbers work, using the $400,000 row: self-employment earnings are 92.35% of $400,000, or $369,400. Social Security is 12.4% of $184,500, or $22,878. Medicare is 2.9% of $369,400, or $10,713, plus 0.9% of the $169,400 above $200,000, or $1,525. That totals $35,115. On a $200,000 salary, payroll tax is $22,878 for Social Security plus 2.9% of $200,000, or $5,800, for $28,678.

This leaves out income tax effects: the deduction for half of self-employment tax and the S-Corp's deduction for the employer half of payroll tax. Those move the result by a few hundred dollars either way. Run your own numbers with the free Sumly S-Corp Calculator.

What does it cost to run an S-Corp?

Running an S-Corp means payroll every month, quarterly payroll filings, a separate business tax return (Form 1120-S) and cleaner bookkeeping than most sole proprietors keep. That typically costs $3,000 to $6,000 a year, and often more at a traditional accounting firm.

Some states add their own tax on S-Corp income:

• California taxes S-Corp net income at 1.5%, with an $800 minimum franchise tax every year after the first.
• Illinois charges S-Corps a 1.5% personal property replacement tax on net income.

These come straight out of the savings in the table. On $200,000 of S-Corp net income, a 1.5% state tax is $3,000 a year, enough to erase most of the net savings at the top of the table.

How does the salary you pick change the answer?

The IRS requires an S-Corp to pay its owner reasonable compensation for the work they do before taking distributions. Reasonable means roughly what the business would pay someone else to do your job. For a senior professional, that number is often well above the wage base.

A lower salary saves more on paper and carries more risk. If the IRS decides your salary was too low, it can treat part of your distributions as wages and charge the payroll tax you skipped, plus penalties and interest. A good analysis shows you several salary levels, what each saves and how defensible each one is, and lets you choose.

When does an S-Corp still make sense for a high earner?

An S-Corp can still be worth it above the wage base when:

• Your profit is well above the salary you can defend, so there is a real distribution to save Medicare tax on.
• Your state does not tax S-Corp income, or taxes it lightly.
• You would pay for monthly bookkeeping and payroll anyway, so the extra cost is small.
• You already made the election. Revoking it generally means waiting five years to elect again, so if the worst case is breaking even, staying put can be the right call.

It is usually not worth it when your salary would be close to your profit, your state taxes S-Corps, or your income swings enough that some years would have no room for distributions.

When do I have to decide?

To make the election for a calendar-year business, file Form 2553 within two months and 15 days of the start of the tax year. For 2027 that is March 15, 2027. You can also file it any time during 2026 for an election that starts January 1, 2027. If you are still deciding, use the next few weeks to get a real projection from your own numbers, not a rule of thumb. Our Tax Savings Calculator is a quick place to start.

FAQ

Does an S-Corp save Social Security tax if I earn over $184,500?

Usually not much. If your S-Corp salary is at or above the 2026 wage base of $184,500, you pay the full Social Security tax on your salary, the same maximum a sole proprietor pays. The savings come mostly from Medicare tax.

How much Medicare tax can an S-Corp save?

2.9% on the profit you take as distributions, plus 0.9% Additional Medicare Tax on self-employment income above $200,000 for single filers. On $169,400 of extra distributions, that is about $6,400 a year before costs.

What is the Social Security wage base for 2027?

$192,300, up from $184,500 in 2026, according to the Social Security Administration.

Can I pay myself a low salary to save more?

You have to pay yourself reasonable compensation for your work. Paying less than a defensible salary raises the risk that the IRS reclassifies distributions as wages.

If I already elected S-Corp status, should I undo it?

Not automatically. After revoking, you generally cannot elect again for five years. If your worst case is roughly breaking even, staying in can be the better choice. Have a tax pro model your best, middle and worst years.
