Search for advice on forming a US company and you’ll find two camps shouting past each other: “always incorporate a Delaware C-corp” and “non-residents should always use an LLC”. Both are wrong as universal rules. The LLC vs C-Corp decision comes down to one question — are you raising venture capital? — and getting it wrong costs you either thousands in unnecessary tax or a painful restructuring later.
This guide breaks down LLC vs C-Corp for non-US founders: how each is taxed, what each really costs, which one investors demand, and how to switch if your plans change.

LLC vs C-Corp: the fundamental difference
An LLC is a pass-through entity. It generally pays no US federal income tax itself; profits pass through to the owner. A foreign owner with no US operations often owes $0 US federal income tax — see our non-resident tax guide for exactly when that applies.
A C-Corp is a separate taxpayer. It pays 21% US federal corporate income tax on its profits. When it distributes what’s left to you as a dividend, the US withholds tax again — 30% for non-residents, reduced (sometimes to 15% or 5%) if your country has a tax treaty with the US. That’s the “double taxation” you keep reading about, and for a profitable small business it’s very real money.
A worked example
The LLC vs C-Corp gap is easiest to see in numbers. Say your business nets $100,000 in profit and you want to take it all home. Under the LLC route, with no US trade or business, you may owe nothing in the US and pay tax only in your home country. Under the C-corp route, the company pays $21,000 in federal tax, and the remaining $79,000 is hit with dividend withholding — 30% without a treaty, which is another $23,700. Same profit, radically different outcome.
That gap is the entire LLC vs C-Corp argument for founders who intend to actually take money out of the business rather than reinvest it while chasing a valuation.
LLC vs C-Corp: full comparison table
| LLC (single-member) | C-Corporation | |
|---|---|---|
| US federal income tax | Pass-through — often $0 for non-residents with no US presence | 21% corporate, then dividend withholding |
| Typical annual state cost | $0 New Mexico / $60 Wyoming | $300+ Delaware franchise tax |
| Annual IRS filing | Form 5472 + pro forma 1120 | Full Form 1120 corporate return |
| Accounting complexity | Low | Higher — corporate books, payroll if salaried |
| Can raise VC money | Difficult — investors resist | Yes — the standard |
| Stock options for a team | Awkward | Designed for it |
| Ownership privacy | Members private in NM/WY | More disclosure |
| Best for | Freelancers, agencies, e-commerce, bootstrapped SaaS | VC-backed startups, accelerators, multiple investors |
LLC vs C-Corp: when the C-Corp is genuinely right
Pick a C-corp — usually Delaware — if any of these describe you:
- You’re raising venture capital within roughly the next 12–18 months. US VC funds are structured so that investing in a pass-through entity creates tax problems for their own investors; most simply won’t do it.
- You’re joining a US accelerator (Y Combinator and most others require a Delaware C-corp).
- You need to issue stock options to employees or advisors on a standard, well-understood plan.
- You’ll have many shareholders or want preferred share classes.
- You intend to reinvest all profits for years and never take dividends — which softens the double-tax problem, since the second layer only bites on distribution.
If you’re in this group, the LLC vs C-Corp question is already settled: accept the tax cost as the price of being fundable.
When the LLC is the better choice
For the majority of non-resident founders we work with, the LLC wins clearly:
- Freelancers and consultants selling services to US clients — see US LLC for freelancers.
- Agencies billing in USD.
- E-commerce and Amazon sellers — the FBA guide covers the specifics.
- Bootstrapped SaaS and digital products, where profits go to the founder rather than to a growth story.
- Anyone whose main goal is US banking, Stripe, and credibility at the lowest ongoing cost.
The LLC gives you the same practical benefits — a real US entity, an EIN, a US bank account, Stripe, liability protection — without the corporate tax layer or the franchise tax.
What both sides of the LLC vs C-Corp choice must file
Neither option lets you skip US paperwork, and this is where founders get hurt regardless of which they chose:
- Foreign-owned single-member LLC: Form 5472 with a pro forma 1120, annually, $25,000 penalty if missed — details in our Form 5472 guide.
- C-Corp: a full Form 1120 corporate return every year, plus Form 5472 if there are foreign related-party transactions.
- Both: a registered agent, and your state’s annual report where one exists. Federal BOI reporting no longer applies to US-formed entities.
Can you change your LLC vs C-Corp decision later?
Yes, and this asymmetry should drive your decision.
LLC → C-Corp is a well-trodden path. Founders do it when a funding round appears; lawyers handle conversions routinely, and investors expect it. You lose little by starting as an LLC.
C-Corp → LLC is messier and can trigger tax on the way out. You may also have paid years of franchise tax and corporate filing fees for a structure that never served its purpose.
So when you’re genuinely unsure, the risk-adjusted answer in the LLC vs C-Corp debate is to start as an LLC and convert if and when real investors arrive with real terms.
Frequently asked questions
Is an LLC or C-Corp better for a non-resident?
For most non-residents, the LLC — pass-through taxation, far lower annual cost, and the same access to US banking and payments. The C-corp is better only when raising venture capital, issuing stock options, or joining an accelerator that requires it.
Do I pay US tax on an LLC if I live abroad?
Often not. With no US office, employees, or dependent agents, a non-resident owner frequently owes no US federal income tax — though the Form 5472 information return is still mandatory. Full explanation in our tax guide.
What about an S-Corp?
Not available to you. S-corporations cannot have non-resident alien shareholders, so the choice for foreign founders is genuinely LLC vs C-Corp only.
Does Delaware matter for an LLC?
Delaware’s advantages are corporate — its case law and courts matter to VCs, not to a single-member LLC. For an LLC you’re mostly buying a $300 annual franchise tax. New Mexico ($0/year) or Wyoming ($60/year) serve you better; see the state comparison and the real cost breakdown.
Can a C-Corp owner avoid double taxation with a salary?
Paying yourself a salary shifts income out of corporate profit, but for a non-resident it introduces payroll, withholding, and potentially US-source compensation issues. It’s a strategy that needs a cross-border CPA, not a blog post.
Choose the structure that matches your plan
Settle the LLC vs C-Corp question by looking at your next 18 months honestly. Raising VC? Go C-corp. Building a profitable business you take money out of? The LLC saves you tax and admin from day one — and stays convertible if the plan changes.
