The LLC vs C-Corp decision for non-US founders depends on three things: how you plan to raise capital, how your home country taxes foreign income, and whether you intend to take money out of the company or leave it inside.
The short version
If you are building a venture-backed startup that will raise institutional capital from US investors, you almost certainly need a C-Corp (specifically a Delaware C-Corp). This is not because C-Corps are better — it's because the US venture capital ecosystem's legal infrastructure is built around C-Corp structures, and deviating from it creates friction that investors won't tolerate at early stages.
If you are running a services business, an e-commerce operation, a consulting practice, or any business where you plan to take profits out rather than raise equity, an LLC is almost always the better choice. It is simpler, cheaper to maintain, and — for most non-resident founders — more tax-efficient.
Why the decision is different for non-residents
For a US citizen, the LLC vs C-Corp question is primarily about double taxation (C-Corp profits are taxed at the corporate level and again when distributed as dividends). For a non-resident, the question has an additional layer: how does your home country treat income from a US entity?
An LLC is a "pass-through" entity for US tax purposes — its income passes through to the owners and is taxed at their level, not the entity level. For a non-resident owner with no US-source income (e.g., selling services to non-US customers through a US LLC), this can mean zero US federal income tax on that income.
A C-Corp is taxed at the entity level (currently 21% federal). When it distributes profits to a non-resident shareholder as dividends, those dividends are subject to a 30% withholding tax — reduced to 15% or lower if your country has a tax treaty with the US.
When to choose an LLC
- You are running a business that generates profit and you want to take that profit out
- You are not raising venture capital from US institutional investors
- Your home country does not have CFC (Controlled Foreign Corporation) rules that would tax undistributed LLC income
- You want the simplest possible US compliance burden
- You are a solo founder or have a small number of co-founders
When to choose a C-Corp
- You are raising or plan to raise venture capital from US investors
- You want to issue stock options to US employees (LLCs can issue equity, but the mechanics are less familiar to US employees and their tax advisors)
- You plan to reinvest all profits rather than distribute them
- Your home country's tax treaty with the US reduces the dividend withholding rate significantly
- You are building toward an acquisition by a US company (acquirers prefer C-Corp targets for structural reasons)
The CFC trap
Some countries — including the UK, Germany, France, Australia, and Japan — have Controlled Foreign Corporation rules that can tax you on the undistributed profits of a foreign company you control. If your country has CFC rules and you choose an LLC, you may owe tax in your home country on profits you haven't actually received.
This does not automatically make a C-Corp better. It means you need to understand your home country's specific CFC provisions before choosing. We maintain country-specific guides that cover the CFC position for each jurisdiction.
The tax treaty question
If your country has a comprehensive income tax treaty with the United States, it may reduce the 30% dividend withholding on C-Corp distributions to 15%, 10%, or even 5%. It may also affect how LLC income is characterised.
Not all treaties are equal, and not all treaty benefits apply to all structures. The US tax treaty guide covers the specific provisions relevant to each country.
Formation costs and ongoing compliance
| LLC | C-Corp | |
|---|---|---|
| Formation cost | $50–$500 depending on state | $50–$500 depending on state |
| Annual state fee | $0–$800 depending on state | $0–$800 depending on state |
| US tax filing | Form 1065 (partnership) or single-member reporting | Form 1120 (corporate return) |
| Complexity | Lower — no board minutes, no stock ledger | Higher — board resolutions, stock certificates, annual minutes |
| Changing later | Can convert to C-Corp (tax-free if done correctly) | Converting to LLC is a taxable liquidation |
The honest answer
Most non-resident founders who are not raising venture capital should form an LLC. Most who are raising venture capital should form a Delaware C-Corp. The edge cases — founders in high-CFC countries, founders with complex multi-entity structures, founders planning both services revenue and future fundraising — are the ones where the answer requires actual analysis rather than a rule of thumb.
If you're in an edge case, book a consultation. If you're not, the rule of thumb is probably right.
