For most non-US founders, start with a US LLC. Choose a C corporation only if you plan to raise money from US venture investors or an accelerator. That is the structure they expect. S-corporation status, the option many guides push, is usually off the table when you are not a US resident.
Lighter paperwork and flexible ownership suit a founder-run software, agency, consulting, or e-commerce business that is not raising venture capital yet.
If US institutional investors are in the plan, a Delaware C corporation is the norm: shares, an option pool, and a board are what term sheets assume.
You can own both as a non-resident, both need an EIN, and even a US LLC with no US income can still owe a yearly IRS filing. General education, not legal or tax advice.
Non-US founders rarely get stuck on the legal theory of LLCs and corporations. They get stuck on one practical question: which one do I file, today, so I can sign contracts, open accounts, and not create a tax mess back home? This page answers that directly, then shows the few facts that should change your answer.
The fast answer, by founder type
Most founders fit one of these patterns. Find yours, then read the rest to confirm.
If you are a non-US founder who… | Usually start with | Why |
|---|---|---|
Runs a SaaS, agency, consulting, or e-commerce business and is not raising VC | LLC | Flexible ownership, fewer formalities, lower ongoing admin. |
Plans to raise from US venture investors or join an accelerator (Y Combinator, Techstars) | Delaware C corporation | Stock, option pools, and SAFEs assume a C-corp; investors expect it. |
Is bootstrapping now but might raise later | LLC now | You can convert an LLC to a C corporation when a round becomes real. |
Mainly wants a US company to bill clients or use a US payment processor | Either | The entity is not what approves you; readiness and documentation are. |
What you are actually choosing between
An LLC is a state-created entity owned by "members." The IRS notes that most states let almost anyone be a member (individuals, companies, and foreign owners), and most states allow a single-member LLC. There is no requirement to issue stock or run a board.
A C corporation is a separate legal entity owned by shareholders, run by directors and officers. It is built to issue stock, bring in investors, and grant employee equity, at the cost of more formality and recordkeeping. New to the basics? Start with what an LLC is and then come back to compare.
How the taxes differ, and the part non-US founders miss
A C corporation is its own taxpayer. It pays a flat 21% federal corporate income tax on profits, and shareholders can be taxed again when profits are paid out as dividends, the "double taxation" you may have read about.
An LLC is more flexible. By default a single-member LLC is "disregarded" (its income flows to the owner) and a multi-member LLC is taxed as a partnership, unless it elects corporate treatment. For many founders, that lighter default is the whole appeal.
But here is the fact that catches non-US founders by surprise:
None of this is a do-it-yourself tax plan. Your country of residence, whether the business is engaged in a US trade or business, any tax treaty, your ownership structure, and how you take money out can all change the outcome. Use this page to choose the entity, then confirm the tax classification and filings with a professional.
What about S-corp status?
S-corp is not a separate company type; it is a federal tax election a corporation or LLC can make, and it carries strict eligibility rules. One of them is decisive here: the IRS does not allow nonresident aliens to be S-corporation shareholders. If you are not a US citizen or US tax resident, S-corp treatment is almost certainly unavailable to you, no matter how many general small-business articles recommend it. Treat any "just elect S-corp" advice as a red flag until your eligibility is confirmed.
Do non-US founders have to file a FinCEN beneficial-ownership (BOI) report?
This changed recently, so older articles get it wrong. Under the FinCEN interim final rule issued in 2025, companies created in the United States (and US persons) are exempt from beneficial-ownership (BOI) reporting under the Corporate Transparency Act. Only a company formed under the law of another country that then registers to do business in a US state is now a "reporting company."
In plain terms: if you form a US LLC or US corporation, that is a domestic entity, so under the current rule there is generally no BOI report to file. You would only hit the BOI rule if you took a company already formed in your home country and registered it to operate in a US state. This area has moved several times. Confirm the current position on the FinCEN BOI page before you rely on it. Not legal advice.
Can you switch later?
Yes, and this is why "start with an LLC" is low-risk. Founders routinely begin as an LLC and convert to a C corporation when a priced round or accelerator makes it necessary. Converting the other way (corporation back to LLC) is the harder, rarer move. If you genuinely do not know yet whether you will raise US venture money, an LLC keeps your costs and admin down while staying convertible. Where you form it is a separate decision; see the best state to form your LLC.
Common mistakes we see from non-US founders
From helping founders outside the US set up their companies, the same avoidable mistakes come up again and again:
Assuming S-corp is on the table. It usually is not for non-residents, and a wrong election creates cleanup work.
Believing "no US income" means "no US filing." The Form 5472 obligation above applies to a foreign-owned LLC even at $0, and the penalty is steep.
Choosing "corporation" because it sounds more serious. If you do not need stock, investors, or an option pool, the extra governance is just overhead.
Expecting the entity to guarantee a bank or Stripe account. A US company helps you get ready; it does not approve you. Plan for documentation and review either way.
Quick FAQ
Is an LLC better than a corporation for non-US founders?
For most, yes. An LLC is the simpler default unless you are raising US venture capital, in which case a Delaware C corporation is the expected structure. "Better" depends on whether you need flexible operations or an investor-ready stock structure.
Can a non-US founder own a US LLC?
Generally yes. The IRS notes that most states do not restrict LLC ownership, so non-US individuals and foreign companies can usually be members, and most states allow a single-member LLC.
Can a non-US founder own an S corporation?
Generally no. The IRS prohibits nonresident aliens from being S-corporation shareholders, so most non-residents cannot elect S-corp treatment.
Is a C corporation better for raising money?
For US institutional fundraising, usually yes. The SBA notes corporations can raise money through the sale of stock, and US investors typically expect a C corporation, most often a Delaware one.
Can I convert from an LLC to a corporation later?
Yes. Starting as an LLC and converting to a C corporation when you raise is a common path, which is why an LLC is a low-risk default if your plans are not settled.

How this article was prepared
CORPBOLT prepared this comparison from primary tax and entity sources, then checked it against how the two structures actually differ for a non-US founder. The federal tax points draw on IRS guidance for LLCs, IRS Form 8832 for entity classification, and IRS material on corporations, alongside the SBA overview of business structures. Editorial review pays special attention to one thing: getting the default-versus-elected tax treatment right, since that is where most comparison articles oversimplify. It is general information, not legal or tax advice, and the right entity depends on your own situation.
Ready to move? Most non-US founders here start an LLC — the full formation process for non-residents walks through every step. You can begin your US LLC formation in a few minutes, and CORPBOLT helps you organize the formation records, EIN steps, and documents banks and platforms tend to ask for.
