LLC vs S Corp: Differences, Taxes and Which to Choose
LLC vs S corp is one of the most searched business questions, and also one of the most confused. An LLC is a legal structure; an S corp is a tax status. Here is how they differ, who can use each one, and what owners outside the US should choose.
An LLC is a type of company you form with a state. An S corp is a federal tax election, and an LLC can choose it. S corp status can cut self-employment tax for profitable US owners who pay themselves a salary. But only US citizens and US residents can own an S corp. If you live outside the US, an S corp is not available to you; a standard LLC (or an LLC taxed as a C corp) is the right choice.
LLC vs S Corp at a Glance
| Point | LLC (default tax) | S corp |
|---|---|---|
| What it is | A legal entity formed with a state | A tax status chosen with the IRS |
| Who can own it | Anyone, from any country | Only US citizens and US residents |
| Number of owners | No limit | Up to 100 shareholders |
| Federal tax | Pass-through to the owners | Pass-through, with salary and distributions split |
| Self-employment tax | On all profit for active US owners | Only on the salary part |
| Payroll | Not needed | Owner-employees must be on payroll |
| Paperwork | Light | More: payroll filings and a separate return |
| Good for owners abroad? | Yes | No, not allowed |
What Is an LLC?
An LLC is a business you register with a state. It protects your personal assets and, by default, passes its profit through to the owners for tax. A single-member LLC is taxed like a sole proprietor; a multi-member LLC is taxed like a partnership. Learn more: what is an LLC.
What Is an S Corp?
An S corp is not a separate kind of company. It is a tax treatment under Subchapter S of the US tax code. A corporation or an LLC files an election with the IRS to be taxed this way. The business still passes profit through to its owners, but owners who work in the business must pay themselves a reasonable salary through payroll. The rest of the profit can be taken as distributions, which are not subject to self-employment tax.
S Corp Eligibility Rules
- No more than 100 shareholders
- Shareholders must be individuals (with limited exceptions such as certain trusts), not other companies
- Every shareholder must be a US citizen or US resident
- Only one class of stock
- The election must be filed with the IRS on time
Why Non-US Residents Cannot Use an S Corp
The rule is strict: a nonresident alien cannot be an S corp shareholder. If even one owner lives outside the US and is not a US citizen or resident, the business cannot be an S corp, and an existing election ends. So for founders in the UK, Pakistan, India, the UAE or anywhere else outside the US, the real choice is between:
- A standard LLC, taxed as a disregarded entity (one owner) or a partnership (several owners). This is the simplest option and suits most online businesses.
- An LLC taxed as a C corporation, which pays corporate tax itself. This can make sense in some cases; compare in LLC vs C corp for non-residents.
LLC vs S Corp Taxes for US Owners
For a US owner earning a solid profit, S corp status can lower the tax bill. Instead of paying self-employment tax on all profit, the owner pays payroll tax only on a reasonable salary. The trade-off is running payroll, filing a separate S corp return and keeping cleaner books. For a low-profit business, the extra cost often outweighs the saving.
Can an LLC Become an S Corp?
Yes. A US-owned LLC can elect S corp tax status and still remain an LLC under state law. Its legal protection does not change; only the way the IRS taxes it changes. This is why “LLC or S corp” is not either-or for US owners: many start as a plain LLC and elect S corp once profit grows.
Which Should You Choose?
| Your situation | Best fit |
|---|---|
| You live outside the US | LLC (default tax), or LLC taxed as a C corp |
| US owner, small or new business | LLC (default tax) |
| US owner, strong steady profit | LLC with an S corp election |
| Raising venture capital | C corporation |

How the Salary and Distribution Split Works
Here is a simple example for a US owner whose business earns $100,000 profit in a year:
| Default LLC | LLC taxed as an S corp | |
|---|---|---|
| How the owner is paid | Takes the profit as the owner | A reasonable salary, for example $60,000, plus a $40,000 distribution |
| Self-employment or payroll tax | On nearly all of the $100,000 | Payroll tax on the $60,000 salary only |
| Income tax | On the full profit | On the full profit (salary plus distribution) |
| Extra costs | None | Payroll service, separate S corp return, cleaner books |
The salary must be reasonable for the work done; the IRS can challenge a salary set too low. The saving is usually worth it only once profit is steady and high enough to cover the extra admin.
Formalities: LLC vs S Corp
| Requirement | LLC | S corp |
|---|---|---|
| Board and officers | Not required | Required if the S corp is a corporation; an LLC electing S status keeps its LLC structure |
| Meetings and minutes | Not required | Expected for corporations |
| Payroll | Not required | Required for owner-employees |
| Profit split | Flexible, set by the operating agreement | Must follow ownership percentages |
How and When to Elect S Corp Status
- The LLC or corporation files Form 2553 with the IRS
- To take effect for a tax year, it is generally filed no more than 2 months and 15 days after that tax year starts
- Every shareholder must sign the election
- S corp status is federal; states recognise it, though a few have their own extra rules
Remember: if any owner is a nonresident alien, the election is not allowed.
S Corp Pros and Cons
| Pros | Cons |
|---|---|
| Can lower self-employment tax for profitable US owners | Only US citizens and residents can own it |
| Profit still passes through to the owners | Owner-employees must run payroll |
| Keeps the LLC’s liability protection | Extra tax return and stricter bookkeeping |
| Familiar to US banks and lenders | Profit must be split by ownership percentage |
The Option for Owners Abroad: An LLC Taxed as a C Corp
Founders outside the US cannot use an S corp, but an LLC can elect to be taxed as a C corporation. The LLC then pays the 21% federal corporate tax on its profit and files a full Form 1120. This can suit businesses that keep profit in the company to grow, or that have US-connected income. For most online and service businesses run from abroad, the default single-member LLC is simpler. Compare in LLC vs C corp for non-residents.
Common Mistakes
- Electing S corp status when one owner lives outside the US, which is not allowed
- Paying a salary that is too low for the work done
- Electing too early, before profit covers the extra payroll and filing costs
- Missing the Form 2553 deadline for the year you want
LLC vs S Corp: FAQs

No. S corp shareholders must be US citizens or US residents. A nonresident owner should use a standard LLC or an LLC taxed as a C corp.
