LLC vs S-Corp vs C-Corp for Non-Residents
Published 20 January 2026 · Updated 31 August 2026 · Reviewed by Ashfaq Khattak, US Tax Consultant
If you are not a US citizen or resident, an S-Corporation is not available to you. The tax code restricts S-Corp shareholders to US citizens and US resident aliens, so the real decision for a non-resident is between an LLC and a C-Corporation.
Choose an LLC if you are a founder, freelancer, agency or e-commerce seller who keeps the profit: no entity-level tax, far lighter compliance, and it can elect corporate treatment later if circumstances change. Choose a C-Corporation if you plan to raise venture capital, grant stock options, or retain profits inside the business. Roughly nine out of ten non-resident founders we work with are better served by an LLC.
The three structures compared
| LLC | S-Corp | C-Corp | |
|---|---|---|---|
| Open to non-residents | Yes - available | No - not available | Yes - available |
| Entity-level federal tax | None; profit passes through | None; profit passes through | 21% on profit |
| Double taxation | No - does not apply | No - does not apply | Yes, on dividends |
| Owner limit | Unlimited, any nationality | 100, US persons only | Unlimited, any nationality |
| Federal return | Pro-forma 1120 + 5472, or 1065 | 1120-S | 1120 |
| Compliance weight | Light | Moderate | Heaviest: board, minutes, resolutions |
| Raising venture capital | Difficult | Difficult | Standard |
| Stock options for staff | No - not available | Limited | Yes - available |
Why non-residents cannot use an S-Corp
An S-Corporation is not a type of company. It is a tax election a corporation or LLC makes with the IRS, and the eligibility rules are strict: no more than 100 shareholders, one class of stock, and every shareholder must be a US citizen, a US resident alien, or certain trusts and estates. A non-resident alien shareholder invalidates the election immediately, and the entity reverts to C-Corporation treatment with back tax owed.
If you become a US resident later, an S-Corp election may become available. Until then, treat it as out of scope.
Choose an LLC when
- You are selling services, software or products and keeping the profit yourself.
- You want the lightest possible annual compliance.
- You want to avoid paying US corporate tax on profit that is not effectively connected to a US trade or business.
- You value the option to elect corporate taxation later without re-forming the company.
Choose a C-Corp when
- You are raising from institutional investors, an accelerator, or on a SAFE. Almost all of them require a Delaware C-Corp.
- You need to grant stock options to employees or advisers.
- You intend to retain profits in the company rather than distribute them, so the 21% corporate rate beats the personal rate that would otherwise apply.
- You want a single, familiar structure for many shareholders across many countries.
The filing obligation nobody escapes
Whichever you pick, the entity files. A foreign-owned single-member LLC with zero revenue still files a pro-forma Form 1120 with Form 5472 attached, and the penalty for missing that is $25,000 per year. A C-Corporation files Form 1120 whether or not it profited. A multi-member LLC files Form 1065 and issues a Schedule K-1 to each member. Filing a return showing nothing is free; not filing is what costs money.
Frequently asked questions
Can a non-US resident own an S-Corporation?
No. An S-Corporation may only have shareholders who are US citizens or US resident aliens. A non-resident alien cannot be a shareholder, so for anyone living outside the US the real choice is between an LLC and a C-Corporation.
Should a non-resident choose an LLC or a C-Corp?
Choose an LLC if you are a founder, freelancer, agency or e-commerce seller keeping the profit yourself: it avoids entity-level tax and has far lighter compliance. Choose a C-Corporation if you plan to raise venture capital, issue stock options to employees, or retain profits inside the company.
Is an LLC taxed twice?
No. A single-member LLC is disregarded and a multi-member LLC is taxed as a partnership, so profit passes through to the owners and is taxed once. A C-Corporation is taxed at 21% on its profit and its shareholders are taxed again on dividends.
Does a foreign-owned LLC still have to file?
Yes. Even a disregarded LLC with no profit files a pro-forma Form 1120 with Form 5472 attached. The penalty for missing it starts at $25,000.
