S-Corp vs LLC (Schedule C): Which Cuts Owner Tax?

For S-Corp vs LLC tax savings, the short answer is this: an LLC by itself does not cut your taxes, but electing S-Corp status can reduce self-employment tax on part of your profit. That savings only shows up above a certain income level, and only if you pay yourself a reasonable salary first. Below that level, the extra cost and paperwork of an S-Corp can wipe out the benefit.

A single-member LLC files Schedule C unless it elects otherwise, so "Schedule C vs S-Corp" is the same decision. The worked example below puts 2026 numbers on it.

What is the real difference between an LLC and an S-Corp?

People treat "LLC" and "S-Corp" like two items on the same menu. They are not. An LLC is a legal entity you form with your state. An S-Corp is a tax status you elect with the IRS. A single-member LLC can elect to be taxed as an S-Corp and keep operating as an LLC in every other way.

By default, a single-member LLC is taxed like a sole proprietorship, and a multi-member LLC is taxed like a partnership. In both cases, the owner pays income tax and self-employment tax on the full net profit. That self-employment piece is where the S-Corp election tries to help.

LLC

A limited liability company: a state-level legal structure that separates your personal assets from the business.

S-Corp election

A federal tax choice (made on IRS Form 2553) that changes how the business's profit is taxed, not how it is legally organized.

Self-employment tax

The Social Security and Medicare tax owners pay on business profit, currently 15.3% up to the Social Security wage base ($184,500 for 2026), then 2.9% above it.

Distribution

Profit paid to an owner that is not classified as wages. In an S-Corp, distributions are generally not subject to self-employment tax.

An LLC decides who can sue you. An S-Corp decides how the IRS taxes your profit. Confusing the two is where owners lose money.

How does an S-Corp actually reduce owner tax?

With a default LLC, all of your net profit is subject to self-employment tax. With an S-Corp, you split that profit into two buckets: a reasonable salary (which is subject to payroll taxes) and distributions (which generally are not subject to self-employment tax).

Here is the concept in plain terms. As a default LLC, self-employment tax applies to the profit. As an S-Corp, the owner takes a reasonable salary and treats the rest as a distribution. The distribution portion avoids Social Security and Medicare tax, which is where the savings come from. The worked example below shows the arithmetic.

But it is not free money. The IRS requires S-Corp owner-employees to pay themselves a reasonable salary for the work they do. If you pay yourself too little to dodge payroll taxes, you invite an audit. The salary must reflect what someone would be paid to do your job.

The S-Corp savings live in the gap between your salary and your profit, but only if the salary is genuinely reasonable.

What counts as a reasonable salary?

The IRS does not publish a single formula. Reasonable salary generally reflects your role, experience, hours, the industry, and what comparable businesses pay for similar work. Factors include your training, your duties, and the time and effort you put into the business. This is an area where working with your CPA matters. The number needs to be defensible if it is ever questioned.

Schedule C vs S-Corp: a worked 2026 example

Take a hypothetical owner whose business nets $200,000 in 2026. On Schedule C, self-employment tax comes to about $28,234. With an S-Corp election and a $90,000 salary, Social Security and Medicare tax comes to $13,770. The $90,000 is an assumption for the arithmetic, not a benchmark; your salary has to fit your own role and market.

How the numbers work. On Schedule C, self-employment tax applies to 92.35% of net profit, because Section 1402(a)(12) first subtracts half of the combined 15.3% rate. The 12.4% Social Security portion stops at the 2026 wage base of $184,500; the 2.9% Medicare portion has no cap. In the S-Corp, only the salary carries these taxes: 6.2% plus 1.45% withheld from you, and the same again paid by the company. The rest of the profit, about $103,115 after the company's $6,885 share of payroll tax, comes out as a distribution without Social Security or Medicare tax.

The gap here is $14,464 of payroll tax, and that is not the net saving. Subtract what the S-Corp adds: a payroll service, a separate Form 1120-S return, and any state entity fees. The income tax side moves too. Reasonable compensation an S-Corp pays you is not qualified business income under Section 199A(c)(4), so the qualified business income deduction can shrink when you elect. Run the full return both ways with your CPA before you decide.

S-Corp vs LLC tax savings: side-by-side comparison

The table below shows the practical trade-offs. Treat it as a concept map, not a promise. Your numbers depend on your income, your state, and current law.

When does an S-Corp election make sense?

The election tends to make sense when profit is high enough and steady enough that the tax savings clearly beat the added cost. Below that point, the payroll service fees, the extra tax return, and the administrative burden can cost more than you save.

A common rule of thumb is that the math often starts working once net profit is comfortably above what a reasonable salary would be, because that leftover profit is what becomes tax-advantaged distribution. But a rule of thumb is not a plan. The real answer depends on your salary level, your state's rules, your retirement plan contributions, and your other income.

Signs the S-Corp conversation is worth having:

• Your net profit is consistent and meaningfully above a reasonable salary for your role.
• You are paying large self-employment tax bills each year.
• You plan to keep the business running for several years, not wind it down soon.
• You are willing to run formal payroll and file a separate return.

The S-Corp is a tool, not a trophy. It rewards steady, above-salary profit and punishes owners who elect it too early.

Where owners get this wrong

The most common mistake is treating the entity election as a standalone tax hack. Your structure interacts with your retirement plan, your health coverage, your payroll, and eventually your exit. An S-Corp salary, for example, affects how much you can put into certain retirement plans; we compare the two main options in SEP IRA vs Solo 401(k). A structure that cuts this year's self-employment tax could limit a bigger opportunity somewhere else. That is why entity choice belongs inside a coordinated plan, not on a spreadsheet by itself.

This is the same gap we cover in tax compliance vs tax strategy: filing the return correctly is not the same as designing the structure that lowers what you owe in the first place.

What an S-Corp does not do

An S-Corp election does not reduce your income tax rate. It does not eliminate taxes. Nothing legal does. It does not protect you more than the LLC already does legally. And it does not run itself: you take on payroll, a separate federal return, and stricter recordkeeping. If those obligations get ignored, the savings can disappear fast in penalties and cleanup costs.

It is also worth remembering that the entity election is one lever among many. Retirement plan design, timing of income, and how you handle a future sale can each move more money than the S-Corp election alone. A proactive structure looks at all of them together.

How Anchor thinks about entity structure

At Anchor, entity choice is not a one-time form. It is part of a coordinated strategy. We function as the fiduciary layer above your CPA and attorney: we design the structure and the surrounding plan, they file and draft. As a fiduciary under the Investment Advisers Act, a duty that applies across the whole advisory relationship, our job is to make sure your entity, your tax plan, your retirement contributions, and your exit strategy are all pulling in the same direction.

Most owners have a CPA who files an accurate return and a structure nobody has revisited in years. The question worth asking is not just "S-Corp or LLC?" It is "does my whole structure still fit where my business and my life are headed?"

Frequently asked questions

Is an S-Corp always better than an LLC for taxes?

No. An S-Corp can reduce self-employment tax once profit is high and steady enough to cover a reasonable salary plus the added payroll and filing costs. Below that point, an LLC taxed normally is often simpler and cheaper. Outcomes depend on your income and current law.

How much does an S-Corp save compared with Schedule C?

It depends on your profit, your salary, and your costs. In the hypothetical 2026 example above, $200,000 of profit carries about $28,234 of self-employment tax on Schedule C, against $13,770 of payroll tax on a $90,000 S-Corp salary. That $14,464 gap is before the S-Corp's payroll and filing costs and before any change in your qualified business income deduction.

Can an LLC be taxed as an S-Corp?

Yes. An LLC stays a legal LLC and separately elects S-Corp tax treatment with the IRS using Form 2553. You keep the LLC structure and change only how the profit is taxed.

What salary do I have to pay myself in an S-Corp?

The IRS requires a reasonable salary that reflects the work you actually do, based on your role, hours, experience, and industry pay. Paying yourself too little to avoid payroll tax is a known audit trigger. Set the number with your CPA so it is defensible.

Does an S-Corp lower my income tax?

No. The S-Corp election is aimed at self-employment tax on the distribution portion of profit, not your income tax rate. Your ordinary income tax still applies to your salary and your share of profit.

What are the downsides of an S-Corp?

You must run formal payroll, file a separate federal return, keep tighter records, and possibly pay state-level fees. If you elect too early or ignore the requirements, those costs and penalties can erase the tax benefit.

Should I decide on structure based only on this year's taxes?

No. Entity choice interacts with retirement plans, health coverage, and your eventual business sale. A structure that saves a little now can limit a larger opportunity later, which is why it belongs inside a coordinated plan rather than a one-year decision.
