Does an S-Corp election actually save the self-employed money?

Sometimes, and far less often than the sales pitch suggests. An S-Corp saves self-employment tax only on the slice of profit you take as a distribution instead of salary, and only at the rate that slice would have been taxed. For most consultants, fractional executives and coaches earning between $80,000 and $200,000 in net profit, the savings are real. Above the Social Security wage base, they shrink fast. The deciding number is the salary you pay yourself.

If you are a freelancer, 1099 contractor, sole proprietor or single-member LLC owner, you have probably been told that electing S-Corp (S corporation) status will "save you 15.3%." This post explains what that number actually covers, walks through a real analysis where the headline savings collapsed to about $390, and gives you the three questions to answer before you file Form 2553.

What does an S-Corp election change?

Nothing about your income tax rate. An S-Corp is a tax election, not a new business. Your LLC keeps operating; the IRS just treats it differently.

As a sole proprietor or single-member LLC, every dollar of net profit is subject to self-employment tax: 12.4% for Social Security and 2.9% for Medicare, which adds up to the 15.3% everyone quotes. The IRS applies that tax to 92.35% of your net profit (IRS: Self-Employment Tax).

Under an S-Corp, you become an employee of your own company. You pay yourself a salary through payroll, and that salary carries Social Security and Medicare taxes (half paid by you, half by the company, same 15.3% total). Whatever profit is left after salary comes out as a distribution, and distributions are not subject to Social Security or Medicare tax.

So the savings formula is simple: 15.3% of the distribution. That is where the pitch usually stops. It should not.

Why doesn't the 15.3% apply to everyone?

Because Social Security tax has a ceiling. In 2026, the 12.4% Social Security portion only applies to the first $184,500 of earnings. Above that, only the 2.9% Medicare portion continues, plus a 0.9% Additional Medicare Tax once earnings pass $200,000 for a single filer (IRS: Additional Medicare Tax).

That ceiling changes the whole picture for high earners. If your reasonable salary already lands above $184,500, Social Security tax is paid in full whether or not you elect S-Corp. Moving profit into distributions saves you only the Medicare portion: 2.9% plus 0.9%, or 3.8%, not 15.3%.

The same logic applies in reverse. A consultant netting $120,000 who can defend a $65,000 salary moves $55,000 into distributions at the full 15.3%, which is roughly $7,000 of payroll tax before costs (less than a straight 15.3% of $55,000, because the sole-proprietor tax he is escaping was only ever charged on 92.35% of profit). A physician netting $425,000 whose market salary is $300,000 or more moves $125,000 at 3.8%, which is roughly $3,500 before costs on the same basis. The second person earns more than three times as much and saves half as much.

A worked example: the firms said yes, the spreadsheet said $390

Recently a self-employed physician asked Sumly to run an S-Corp analysis. He had already spoken with several accounting firms, and all of them projected meaningful savings. He wanted a second opinion before filing.

Here is what his year looked like, annualized from nine months of actual bank data:

• Net profit: about $425,000

• Self-employment tax as a sole proprietor: $34,268, plus $1,735 of Additional Medicare Tax

• Reasonable salary: employed physicians in his specialty and city earn roughly $320,000 to $420,000

We modeled four salary levels. At a conservative $290,000 salary, the payroll tax savings were about $2,970, plus $920 of Additional Medicare savings. Then the costs came in:

• His state charges S-Corps an entity-level tax on net income that sole proprietors do not pay. State fees: about $1,790.

• Payroll, bookkeeping and the S-Corp return run about $2,972 a year, even on a lean setup.

• As a sole proprietor he deducts half of his self-employment tax. As an S-Corp owner he loses that deduction and gains a different one (the employer half of payroll tax), and the two nearly cancel at his bracket.

Net annual savings after tax: about $390. At a $390,000 salary, the most defensible level for his profession, the election would cost him about $1,850 a year. Only at an aggressive $210,000 salary, which an IRS examiner could easily challenge for a physician earning $425,000, did savings reach about $2,170.

Why did the other firms land somewhere else? Most S-Corp estimates apply 15.3% to the whole distribution, skip the Social Security ceiling, ignore state entity taxes, and leave out the lost self-employment tax deduction. Each shortcut adds a few thousand dollars of imaginary savings.

When does an S-Corp election make sense?

The election tends to pay off when three things are true at once:

1. Your net profit is comfortably above your reasonable salary. A common rule of thumb is net profit of $80,000 or more with a defensible salary well below it. The gap between the two is the only income that saves anything.

2. Your reasonable salary sits below the Social Security wage base. That keeps the savings rate at 15.3% rather than 3.8%. Setting and documenting that number is its own exercise: How do you set a reasonable salary for your S-Corp?

3. Your savings clear the costs by a wide margin. Budget $3,000 to $6,000 a year for payroll, an extra tax return and bookkeeping, and often more at a traditional accounting firm, plus any state-level S-Corp taxes. If the projected savings are not at least double that, the election is not worth the added admin. The full list is in What are the hidden costs of an S-Corp?

For fractional executives and independent consultants, this often means the S-Corp question gets interesting somewhere between $100,000 and $250,000 of net profit, and gets interesting again only at very high profit levels where even a 3.8% rate on a large distribution adds up.

Among Sumly users, 48% run an LLC and 44% are sole proprietors; only about 6% have elected S-Corp status. If you have not elected yet, you are in good company. What matters is whether your numbers have changed.

What should you check before you file Form 2553?

Ask whoever is recommending the election to show you three numbers in writing:

• The salary they assumed. If they cannot explain how they picked it, the savings estimate is a guess.

• The savings rate they applied. If your salary is above $184,500 and they used 15.3%, the estimate is wrong.

• The annual cost of compliance in your state. Payroll software, the S-Corp return, state entity taxes and registered agent fees all count.

Then run your own numbers. The Sumly Tax Savings Calculator shows what you are likely overpaying as a sole proprietor today, which is the baseline any S-Corp projection has to beat.

FAQ

Is 15.3% the real self-employment tax rate?

Yes for 2026 income up to $184,500. Above that, only the 2.9% Medicare portion applies, plus 0.9% Additional Medicare Tax above $200,000 of earned income for single filers ($250,000 married filing jointly).

Can I just pay myself a very low salary to maximize savings?

The IRS requires S-Corp owners who work in the business to pay themselves reasonable compensation for the work they do. Salaries far below market invite reclassification of distributions as wages, plus penalties. Every S-Corp analysis lives or dies on this number.

Does an S-Corp affect the QBI deduction?

It can. Wages paid to yourself reduce qualified business income, so the 20% QBI deduction often shrinks after an election. Professionals in specified service fields (medicine, law, consulting, financial services) may already be phased out of QBI at higher incomes, in which case there is no trade-off either way.

Are there states where an S-Corp costs extra?

Yes. Illinois charges a 1.5% replacement tax on S-Corp net income, and California imposes a 1.5% tax on S-Corp net income with an $800 minimum. Some cities add their own. Always include state and local costs in the math.

What is the deadline to elect S-Corp status?

Form 2553 is generally due within two months and 15 days after the start of the tax year you want the election to apply to, so March 15 for a calendar-year business. Late elections are sometimes accepted with a reasonable-cause statement.

Should I undo my S-Corp election if the savings are small?

Possibly, but revoking has its own rules and a five-year waiting period before you can re-elect. Talk to a tax pro before changing structure in either direction.
