Quick answer: An LLC is a type of legal business entity you form with your state. An S Corp is not a separate entity type; it’s a federal tax election that an LLC or corporation can choose by filing IRS Form 2553. So the real question for most owners is: should my LLC stay taxed the default way, or elect S corp taxation? The S corp election can lower self-employment taxes once profits are high enough, often around $60,000–$80,000 or more a year, but it adds payroll, a separate tax return, and other costs.
The Key Point Most Guides Miss
You don’t have to choose between “an LLC” and “an S corp.” Common setups:
| Setup | Legal entity | How it’s taxed |
|---|---|---|
| Single-member LLC (default) | LLC | Like a sole proprietorship (Schedule C) |
| Multi-member LLC (default) | LLC | Like a partnership (Form 1065) |
| LLC taxed as an S corp | LLC | S corporation (Form 1120-S) |
| Corporation with S election | Corporation | S corporation (Form 1120-S) |
| Corporation (default) | Corporation | C corporation (Form 1120) |
Many small business owners form an LLC for its simplicity and liability protection, then elect S corp status later when the tax savings justify it.
What Is an LLC?
A limited liability company is a business entity created under state law. Key features:
- Liability protection: owners (members) generally aren’t personally responsible for the company’s debts and lawsuits, as long as they keep business and personal finances separate.
- Flexible ownership: any number of members, including non-U.S. residents and other companies.
- Flexible taxation: by default, profits “pass through” to the owners’ personal returns. An LLC can also elect S corp or C corp taxation.
- Fewer formalities: usually an operating agreement and an annual state report. No required board meetings.
Main tax drawback: under default taxation, owners who work in the business pay self-employment tax (15.3%) on most of their profit, not just on what they take home.
What Is an S Corp?
An S corporation is a company that has elected to be taxed under Subchapter S of the Internal Revenue Code. Profits pass through to owners’ personal returns, so there’s no corporate-level federal income tax.
IRS eligibility rules (Form 2553 instructions):
- Must be a domestic corporation or eligible entity (such as an LLC)
- No more than 100 shareholders (family members can count as one)
- Shareholders must be individuals, certain trusts, estates or certain tax-exempt organizations. No partnerships, corporations or nonresident aliens.
- Only one class of stock (differences in voting rights are allowed)
The salary rule: owners who work in the business must be paid “reasonable compensation” through payroll before taking other distributions, according to the IRS. The IRS looks at factors such as your duties, experience, time spent and what comparable businesses pay for similar work.
How the Taxes Actually Differ
With a default LLC: all of your net profit (roughly 92.35% of it) is subject to self-employment tax of 15.3%: 12.4% Social Security (on earnings up to $184,500 in 2026) plus 2.9% Medicare.
With an S corp election: only your salary is subject to payroll taxes (the same 15.3%, split between you and the company). The rest of the profit you take as distributions, which are not subject to Social Security or Medicare tax.
Important correction: S corp distributions are not taxed at a lower “dividend” rate. They’re still taxed as ordinary income on your personal return. The savings come only from avoiding payroll/self-employment tax on the distribution portion.
Example: $100,000 in Profit
Simplified illustration for a single owner; it ignores state taxes and other deductions.
| Default LLC | LLC taxed as S corp ($60,000 salary) | |
|---|---|---|
| Amount subject to SE/payroll tax | ~$92,350 | $60,000 |
| SE/payroll tax at 15.3% | ~$14,130 | ~$9,180 |
| Difference | ~$4,950 less |
From that ~$4,950 you’d subtract the extra costs of an S corp: payroll service, a separate Form 1120-S return (often several hundred to a few thousand dollars from a CPA), possible state fees, and unemployment taxes on your salary. Net savings in this example could be roughly $2,000–$3,500 a year, and less if your “reasonable salary” must be higher.
The QBI Deduction
Both setups can qualify for the 20% qualified business income (QBI) deduction, which the 2025 tax law (the One Big Beautiful Bill Act) made permanent. One trade-off: in an S corp, your salary doesn’t count as QBI, so a higher salary can slightly reduce this deduction.
S Corp vs LLC: Side-by-Side
| Factor | LLC (default tax) | S corp election |
|---|---|---|
| Liability protection | Yes | Yes (from the underlying LLC or corporation) |
| Owners | Unlimited; any type | Up to 100; U.S. individuals and certain trusts/estates |
| Self-employment tax | On nearly all profit | Only on salary |
| Payroll required | No | Yes, for working owners |
| Federal return | Schedule C or Form 1065 | Form 1120-S |
| Profit splitting | Flexible | Must follow ownership percentages |
| Paperwork and cost | Lower | Higher |
| Best for | New or lower-profit businesses, real estate, multiple owner types | Established, profitable service businesses |
When Should an LLC Elect S Corp Status?
An S corp election often makes sense when:
- Your business has steady profit, often $60,000–$80,000+ a year after expenses
- You work in the business and can justify a reasonable salary below your total profit
- You’re comfortable running payroll and paying for an extra tax return
- All owners are eligible shareholders
It usually doesn’t make sense when:
- Profits are low or unpredictable
- You hold mainly rental real estate (rental income generally isn’t subject to SE tax anyway, and an S corp can complicate property moves)
- You have foreign owners or company owners
- You want to split profits differently from ownership percentages
- You plan to raise venture capital (investors usually want a C corp)
How to Elect S Corp Status
- Form your LLC (or corporation) with your state and get an EIN.
- File IRS Form 2553 no more than 2 months and 15 days after the start of the tax year the election should take effect, or at any time during the prior year. An LLC can file Form 2553 directly; it doesn’t need to file Form 8832 first.
- Set up payroll and pay yourself a reasonable salary.
- File Form 1120-S each year and give each owner a Schedule K-1.
- Check your state: some states tax or treat S corps differently.

FAQs
Is an S corp better than an LLC? Neither is “better.” An LLC is a legal structure and an S corp is a tax election. Many owners use both: an LLC taxed as an S corp.
Can an LLC be an S corp? Yes. An eligible LLC can elect S corp taxation by filing IRS Form 2553.
At what income does an S corp make sense? Often around $60,000–$80,000+ in annual profit, but it depends on your reasonable salary, state taxes and extra costs. Ask a tax professional to run your numbers.
Are S corp distributions tax-free? No. They’re taxed as ordinary income, but they aren’t subject to Social Security and Medicare taxes.
What is reasonable compensation? The salary a business would pay someone else to do your job, based on factors like duties, experience and industry pay. The IRS can reclassify distributions as wages if your salary is too low.
Can I go back from an S corp to a regular LLC? Yes, you can revoke the election, but you generally can’t re-elect S corp status for five years.
