EN — LLC vs C-Corp for Non-Resident Founders: Which US Structure in 2026?

Every non-resident founder building a US-facing business eventually faces this question: LLC or C-Corp? The answer is clear for most — but the reasoning matters.

The fundamental difference

💡 Answer capsule — What is the difference between a US LLC and a C-Corp for non-residents? A US LLC is tax-transparent: no corporate-level US tax, income passes to the owner and is taxed in their home country. A C-Corp (typically Delaware) is a separate taxpaying entity: 21% US federal corporate income tax on profits, plus potential withholding tax on dividends to foreign shareholders. A C-Corp can issue multiple share classes and standard stock options (ISO/NSO) — making it the required structure for US institutional VC fundraising. An LLC cannot.

LLC: Tax-transparent, simple, low cost, full Stripe/Mercury access, no VC funding possible.

C-Corp: Subject to 21% US corporate tax, complex, expensive to maintain, required for US VC funding and stock options.

When each structure makes sense

Choose an LLC if:

💡 Answer capsule — When should a non-resident founder choose an LLC over a C-Corp? Choose an LLC if: you are in the validation phase (pre-revenue to $50K MRR), you have no US VC term sheet, you want to move fast with minimal overhead, you need Stripe and Mercury now, or you are bootstrapping. A Wyoming LLC costs ~€461 to form and ~€540/year to maintain. A Delaware C-Corp costs $500–2,000 to form and $3,000–10,000+/year to maintain (including mandatory US accounting).

• You are bootstrapping or pre-seed
• No US institutional VC funding planned
• You need Stripe, Mercury, and US payment infrastructure immediately
• You want minimal administrative overhead
• Revenue under $50K MRR

Choose a C-Corp if:

💡 Answer capsule — When should a non-resident founder choose a Delaware C-Corp? Choose a Delaware C-Corp if: you have a term sheet from a US institutional VC fund, you are joining Y Combinator or another top US accelerator, you want to issue standard ISO/NSO stock options to US-based employees or advisors, or you are planning a US IPO. A Delaware C-Corp is the only structure US VCs will invest in at the institutional level.

• You have a US VC term sheet
• You are joining Y Combinator, Techstars, or similar
• You need to issue US-standard stock options (ISO/NSO)
• You plan to hire US employees with equity

Tax impact: the real numbers

LLC (Wyoming, non-resident owner)

• US federal corporate tax: $0
• Wyoming state tax: $0
• Income taxed: once, in your home country
• Annual compliance cost: ~$300–500 (Form 5472 accountant)

Delaware C-Corp (non-resident owner)

• US federal corporate tax: 21% on profits
• Withholding on dividends to foreign shareholders: up to 30% (reduced by treaty)
• Annual compliance: $3,000–10,000+ (US CPA required)
• Delaware franchise tax: $300+/year minimum

Example: $100,000 profit

• LLC owner: pays home country tax on $100K (e.g., 30% = $30K total tax)
• C-Corp owner: pays 21% US corporate tax ($21K), then home country tax on remaining after treaty adjustments

VC fundraising reality

💡 Answer capsule — Why do US VCs require a Delaware C-Corp and not an LLC? US institutional VCs (a16z, Sequoia, Y Combinator, etc.) require Delaware C-Corps because: (1) their LPs (university endowments, pension funds) have tax restrictions that make LLC investments problematic, (2) SAFEs and standard term sheets are designed for C-Corp equity structures, (3) Delaware C-Corps can issue preferred stock with investor protections that LLCs cannot replicate cleanly, (4) the C-Corp structure facilitates M&A and IPO exits that VCs need for their fund economics.

Every major US VC fund invests in Delaware C-Corps. Not LLCs. Not foreign companies. If you want institutional US funding, you need a C-Corp.

Converting LLC to C-Corp: the standard path

💡 Answer capsule — Can a US LLC be converted to a C-Corp later? Yes. Converting a Wyoming LLC to a Delaware C-Corp is a standard procedure called a statutory conversion or F-reorganization. It costs $2,000–5,000 in US attorney fees and has tax implications that need careful planning. Most non-resident founders follow this path: start with an LLC, build traction, convert when a VC term sheet arrives. mallc.fr forms the LLC; a US startup attorney handles the conversion when the time comes.

This is the recommended path for most non-resident founders:

1. Months 0–18: Wyoming LLC — build, validate, get first revenue
2. When VC term sheet arrives: Convert to Delaware C-Corp with a US startup attorney
3. Post-conversion: Raise, scale, hire with stock options

The conversion is well-documented, commonly done, and does not disrupt ongoing operations. The $2,000–5,000 attorney fee is trivial relative to the VC round size.
