LLC vs S Corporation in 2026: Which Entity Structure Saves Business Owners More in Taxes?

Why your entity structure can change your tax bill

The LLC vs S corporation question comes up in almost every first meeting we have with a growing business owner. The answer can be worth thousands of dollars a year, or it can cost you money if you choose too early.

Here is the core issue. If you run a profitable single-member LLC or a sole proprietorship, the IRS generally taxes all of your net profit for self-employment tax. That tax is 12.4% for Social Security plus 2.9% for Medicare, applied to 92.35% of your net earnings. An S corporation works differently: you pay yourself a salary that carries payroll tax, and the remaining profit can be taken as distributions that are not subject to that tax.

At J&E Advisory Group, we help owners decide whether that tradeoff is worth it. It is not always worth it, and the right time to decide is now, before the year ends.

LLC vs S corporation: what each one actually is

An LLC is a legal structure created under state law. It protects your personal assets from many business debts. It is not a tax category by itself. A single-member LLC is taxed like a sole proprietorship by default, and a multi-member LLC is taxed like a partnership.

An S corporation is a tax election, not a type of company. A corporation or an LLC can ask the IRS to be taxed as an S corporation by filing Form 2553. Many of our clients keep their LLC and simply add the S election on top.

To qualify, the IRS requires all of the following:

• It must be a domestic entity.
• It can have no more than 100 shareholders.
• Shareholders must be individuals, estates, certain exempt organizations or certain trusts, and none can be a nonresident alien.
• It can have only one class of stock, meaning all shares carry identical rights to distributions and liquidation.
• Every shareholder must consent to the election.

The nonresident alien rule matters for our international clients. A foreign national owner generally cannot hold shares in an S corporation, so entity planning for cross-border owners starts with different questions. We cover those through our international tax practice.

S corporation payroll tax savings: how the math works

Here is a simple illustration. It is hypothetical, and your numbers will differ.

Say your business nets $150,000 before any owner pay.

As a sole proprietor or default LLC, self-employment tax is about 15.3% of 92.35% of $150,000. That is $138,525 times 15.3%, or roughly $21,194. All of your profit is below the 2026 Social Security wage base of $184,500, so the full 12.4% Social Security portion applies.

As an S corporation paying you a reasonable salary of $80,000, payroll tax is 15.3% of $80,000, or $12,240 combined employer and employee share. The other $70,000 is a distribution that does not carry payroll tax.

The gross difference is about $8,954. The real savings is smaller. You pay for payroll processing, a separate corporate tax return (Form 1120-S), possible state-level costs and more bookkeeping. A lower salary also lowers the base for retirement contributions and can reduce the qualified business income deduction we discuss below.

As a rule of thumb, owners earning less than roughly $60,000 to $80,000 in net profit often find the extra cost cancels the benefit. That is a planning guideline, not an IRS rule. We run the numbers for each client.

The reasonable compensation rule

This is where S corporation owners get into trouble. The IRS treats an officer who performs services for the company as an employee, and pay for those services is wages. The IRS has said S corporations should not try to avoid employment taxes by labeling officer pay as distributions, loans or personal expense payments.

There is no formula in the tax code. The IRS and the courts look at the facts, including:

• Your training and experience.
• Your duties and the time you devote to the business.
• What comparable businesses pay for similar work.
• What you pay non-owner employees.
• Your history of salary versus distributions.

Practical advice: document how you set your salary, such as with compensation surveys for your role and region. Run payroll on a regular schedule. Do not take large distributions in a year when you paid yourself little or nothing.

The qualified business income deduction in 2026

The qualified business income (QBI) deduction lets many pass-through owners deduct up to 20% of their qualified business income. It applies to sole proprietors, partnerships and S corporations. Pass-through owners should know three 2026 points.

• The 2026 taxable income threshold, where limits begin to apply, is $403,500 for joint filers and $201,750 for single filers. The phase-in range ends at $553,500 and $276,750.
• For tax years beginning after 2025, a minimum deduction of $400 applies for active business owners with at least $1,000 of qualified business income.
• Above the threshold, the deduction can be limited by the W-2 wages your business pays and the basis of its property. Owners of specified service businesses, such as many medical, legal and consulting practices, can lose the deduction as income rises.

Here is why this matters to the S corporation decision. Your salary counts as W-2 wages, but it is not qualified business income. A higher salary can reduce the QBI deduction, and a lower salary can raise IRS risk. Good planning looks at payroll tax savings, the QBI deduction and retirement contributions together, not one at a time.

Equipment purchases: Section 179 and bonus depreciation

Year-end entity planning often overlaps with equipment buying. Two tools matter for 2026.

• Section 179 lets you expense qualifying equipment in the year you place it in service. The 2026 limit is $2,560,000, reduced dollar for dollar once total purchases pass $4,090,000. The cap for certain heavy SUVs is $32,000.
• Bonus depreciation is a permanent 100% first-year deduction for qualified property acquired after January 19, 2025.

Both work for LLCs and S corporations. The deduction must still be tied to a real business need. Buying equipment you do not need just to create a deduction is a poor trade.

Timing: when to make the S corporation election

Form 2553 is generally due no more than 2 months and 15 days after the start of the tax year in which you want the election to take effect. You can also file it at any time during the prior tax year.

That second rule is the year-end opportunity. A calendar-year business that files before December 31, 2026, can have the S election take effect on January 1, 2027, with no deadline scramble.

If you missed the deadline, relief may be available. Under Revenue Procedure 2013-30, the IRS may accept a late election if you intended to be an S corporation, the late filing was the only reason you did not qualify, you act diligently once you find the error, and you file within 3 years and 75 days of the intended effective date. If those conditions are not met, a private letter ruling and user fee may be required.

Also remember the election is not free to undo. Revoking it has its own rules, and you cannot always re-elect right away. Treat it as a multi-year decision.

Common mistakes with entity structure

• Electing S status too early, before profit can support the added cost.
• Setting salary at a token amount to push more income into distributions.
• Mixing personal and business spending, which weakens liability protection and makes the books unreliable.
• Skipping estimated tax payments. Our guide on estimated tax penalties explains how to avoid them: https://www.jeadvisorygroup.com/blogs/estimated-taxes-are-a-pain-here-s-how-to-avoid-costly-penalties
• Ignoring state rules. Some states tax or charge fees to S corporations differently from the federal system.
• Forgetting that more entities means more bookkeeping. Clean monthly books are the foundation of any structure: https://www.jeadvisorygroup.com/blogs/small-business-bookkeeping-basics-monthly-checklist

A year-end checklist for business owners

1. Review year-to-date profit and project it through December 31.

2. Compare your self-employment tax today with a modeled S corporation scenario, including payroll and compliance costs.

3. Set a reasonable salary range and document how you chose it.

4. Decide whether any equipment purchases make sense for Section 179 or bonus depreciation.

5. If you want the S election for 2027, file Form 2553 before December 31, 2026.

6. Update your retirement plan design for the new year. Our post on small business 401(k) plans can help: https://www.jeadvisorygroup.com/blogs/why-more-small-businesses-are-turning-to-401-k-plans-in-2026

Frequently asked questions about LLC vs S corporation

Is an S corporation better than an LLC for taxes?

They are not opposites, because an LLC can elect to be taxed as an S corporation. The S election can reduce self-employment tax when profit is high enough, but it adds payroll and compliance costs. Whether it saves money depends on your profit, your salary and your state.

At what profit level does an S corporation make sense?

There is no IRS threshold. Many advisors look at net profit above roughly $60,000 to $80,000 as the point where savings can start to outweigh the added costs. We model each client individually.

How much salary do I have to pay myself as an S corporation owner?

The law requires reasonable compensation for the services you perform. There is no fixed percentage. Factors include your duties, experience, hours and what similar businesses pay.

When is the deadline to elect S corporation status?

Generally 2 months and 15 days after the start of the tax year the election takes effect, or any time during the prior tax year. For a January 1, 2027 effective date, filing before the end of 2026 avoids a rush.

Can I change my mind after electing S status?

You can revoke the election, but rules apply and you may be barred from re-electing for a period. Treat the decision as long term.

Can I get relief if I missed the Form 2553 deadline?

Possibly. Revenue Procedure 2013-30 allows late-election relief when you meet several conditions, including filing within 3 years and 75 days of the intended effective date and showing reasonable cause.

Does the S election affect my QBI deduction?

It can. Your salary is W-2 wages, not qualified business income, so a higher salary can reduce the deduction. W-2 wages can also help you above the income thresholds. The two need to be planned together.

Can a foreign national or nonresident own an S corporation?

Generally no. Nonresident aliens cannot be S corporation shareholders. Foreign owners and U.S. owners with foreign business interests may need a different structure and additional reporting, such as FBAR.
