LLC vs S-Corp Comparison
An LLC is a legal structure, and an S corporation is a tax status. They are not opposites. An LLC can elect to be taxed as an S corporation, and that election can lower self-employment tax for a working owner who has profit well above a reasonable salary. The catch is that S-corp shareholders must be US citizens or residents, so most non-US founders cannot use the election at all.
Key takeaways
- "LLC" describes how the company is organised; "S corporation" describes how it is taxed.
- Both give the owner limited liability, when the company is run properly.
- A default LLC owner pays self-employment tax on all profit, while an S-corp owner pays payroll tax only on salary.
- S-corps can have only US citizen or resident individuals (and certain trusts and estates) as shareholders.
- An S election adds payroll, extra filings and the need to pay a reasonable salary.
The short version: what each one is
An LLC is created by filing with a state. It protects the owners' personal assets from most business debts and gives flexibility over management and profit sharing. For tax, the IRS treats it by default as a sole proprietorship (one owner) or a partnership (two or more). The owner is not an employee.
An S corporation is a corporation, or an LLC that has elected to be treated like one, that files Form 2553 to pass profit through to its shareholders without a company-level income tax. Working owners are employees and must be paid a reasonable wage. That wage carries payroll tax.
How the tax differs
The main reason people ask about an S election is self-employment tax. A default LLC owner pays it on nearly all net profit. Under an S election the owner pays payroll tax on salary only, and the remaining profit is paid out as distributions that are not subject to that tax.
| Component | Rate |
|---|---|
| Social Security portion | 12.4% |
| Medicare portion | 2.9% |
| Additional Medicare tax (high earners) | 0.9% |
The Social Security and Medicare rates together are the 15.3 percent described in our self-employment tax guide. Under a default LLC they apply to the owner's net earnings. Under an S corporation they apply to the salary, which is normally lower than total profit.
Side-by-side comparison
| Feature | Default LLC | LLC taxed as S-corp |
|---|---|---|
| Liability protection | Yes | Yes |
| Owner is paid by | Draws or distributions | Salary plus distributions |
| Payroll required | No | Yes, for working owners |
| Self-employment tax | On net earnings | Only through salary |
| Federal return | Schedule C or Form 1065 | Form 1120-S |
| Who may own it | Anyone, including non-US persons | US citizens and residents only |
| Profit sharing | Flexible | Strictly by share ownership |
The last two rows decide the question for many people reading this site. An S corporation can have only one class of stock and cannot have non-resident alien shareholders. If you live in India, Nigeria, the UAE or the UK and are not a US tax resident, you cannot be an S-corp shareholder.
When an S election can make sense
An S election is worth a look if all of the following are true:
- You are a US citizen or US tax resident.
- The business earns steady profit, not just a few thousand dollars.
- Profit is comfortably higher than a reasonable salary for your role.
- You are ready to run payroll, file quarterly returns and keep tighter books.
The saving comes from profit above the salary. If your profit is close to a reasonable salary, there is little to save and the extra cost of payroll and a separate return may erase it. Extra costs include payroll software, a tax preparer for Form 1120-S and state fees for corporations in some states.
What "reasonable salary" means
The IRS looks for a wage similar to what you would pay someone else to do your work. Setting salary at a token amount to avoid payroll tax invites an audit and an adjustment. Factors include your duties, hours, training and what comparable businesses pay. Document how you set the figure.
What non-US founders should do instead
If an S election is closed to you, the alternatives are still workable:
- Keep the default single-member LLC. As a nonresident alien you generally pay no self-employment tax, and the LLC taxation rules often keep US tax low or nil for income earned outside the US.
- Elect C-corporation treatment, or form a C-Corp directly, if you need a structure that investors know. Read LLC vs C-Corp and how to form a C-Corp.
- Pay yourself through draws and plan your home-country tax with a local accountant. See how to pay yourself from your LLC.
Whichever route you choose, this is general information rather than tax advice, and your own facts should be confirmed with a CPA.
How to elect S-corp status
If you are eligible, the steps are:
- Form the LLC and get an EIN.
- Have every member sign Form 2553.
- File it with the IRS within the deadline: generally within two months and 15 days of the start of the tax year the election takes effect.
- Set up payroll and start paying yourself a salary.
- Check your state. Some states tax S corporations differently or charge a fee.
Late-election relief exists, but it is not automatic, so do not rely on it.
A rough example for a US-resident owner
Consider a US-resident owner with $120,000 of net profit and a reasonable salary of $60,000. As a default LLC, self-employment tax applies to most of the $120,000. With an S election, payroll tax applies only to the $60,000 salary, and the other $60,000 comes out as a distribution. The difference in payroll-type tax can run to a few thousand dollars a year, less the cost of running payroll, the extra return and any state fee.
Your numbers will differ, because income tax, state rules and the qualified business income deduction all interact. The example shows the shape of the trade, not a promise. A CPA can run both scenarios on your figures before you file Form 2553.
How to decide in three questions
- Are you a US citizen or tax resident? If not, the election is closed and you can stop here.
- Is profit well above what you would pay an employee to do your job? If not, the saving is small.
- Are you willing to run payroll and keep clean books all year? If not, the extra work may cost more than it saves.
Answering yes three times makes the election worth a serious look. Anything else, and a default LLC usually stays the simpler choice.
Common misunderstandings
"An S-corp is a different kind of company"
It is a tax label. Your legal structure can stay an LLC. You do not need to re-form the company.
"An S-corp means no tax"
Profit is still taxed, at the shareholder level. The saving relates to payroll-type taxes, not income tax.
"Any owner can pick it"
Eligibility rules on shareholders are firm. A foreign individual as a member disqualifies the election.
Frequently asked questions
Is an LLC better than an S-corp?
They solve different problems. An LLC is simpler. An S election can reduce payroll-type tax for a profitable US-resident owner but adds cost and paperwork.
Can a non-US resident own an S-corp?
No. S-corp shareholders must be US citizens or residents, with limited exceptions for certain trusts and estates.
Can an LLC be an S-corp?
Yes, if it files Form 2553 and meets the eligibility rules. It stays an LLC under state law.
Do S-corp owners need payroll?
Yes. Owners who work in the business must be paid a reasonable salary through payroll.
What if I am a non-US founder who wants lower tax?
Look at your residency, where the income is earned and what your home country taxes. A CPA who works with foreign owners can model the options.
