The entity type you choose affects your tax treatment, investor compatibility, and operational complexity. Here's how to decide.
An LLC (Limited Liability Company) and a C-Corporation are both legal structures that separate your personal assets from your business liabilities. That protection is the same for both. The differences are in how they are taxed, how equity is structured, and who will invest in them.
For international founders, the choice almost always comes down to one question: Are you raising institutional venture capital in the near term?
If yes → C-Corp (Delaware). If no → LLC (Wyoming, typically).
The longer explanation follows, but that's the summary.
The default tax treatment for a single-member LLC is as a disregarded entity — the IRS treats the LLC as if it doesn't exist for federal income tax purposes. The owner reports business income directly on their personal tax return (or, for a foreign owner with no U.S. personal tax filing obligation, the business income may pass through without triggering U.S. personal income tax at all, depending on circumstances).
For a multi-member LLC, the default is partnership taxation — profits and losses flow through to each member proportionally, and each member reports their share on their own tax return.
Key advantages of LLC pass-through taxation:
For foreign-owned LLCs specifically:
A foreign-owned single-member LLC with no U.S. trade or business and no effectively connected income generally does not pay U.S. federal income tax. However, it must file Form 5472 and a pro forma 1120 annually — a filing requirement that is completely separate from whether you owe taxes. See our Form 5472 article for why this matters enormously.
A C-Corporation is a separate taxable entity. The corporation pays corporate income tax on its profits (currently 21% federal rate in the U.S.). When it distributes profits to shareholders as dividends, those shareholders pay income tax on those dividends in their own jurisdiction. This is "double taxation" — the profit is taxed once at the corporate level and again at the shareholder level.
When double taxation doesn't hurt:
Most VC-backed C-Corps don't distribute dividends — profits are reinvested into growth. Founders and investors exit through acquisition or IPO, where gains are taxed as capital gains (typically at a lower rate). In that model, the double taxation concern is largely theoretical during the growth phase.
For foreign shareholders of a C-Corp:
A foreign person receiving dividends from a U.S. C-Corp is subject to U.S. withholding tax (typically 30%, reduced by tax treaty). This is another reason most international founders should think carefully before choosing C-Corp unless they have a specific reason for it.
Institutional venture capital firms — accelerators like YC, traditional VCs like Sequoia or a16z — almost universally require their portfolio companies to be organized as Delaware C-Corporations before they invest. There are structural reasons for this:
Preferred stock: VCs invest in exchange for preferred stock — a share class with liquidation preferences, anti-dilution rights, and other investor protections. LLCs can have membership interests with economic preferences, but the mechanics are messier and the legal infrastructure is less mature.
83(b) elections: When founders receive shares subject to vesting, they should file an 83(b) election with the IRS within 30 days of grant to elect to be taxed on the shares immediately at their low fair market value, rather than as they vest at potentially much higher values. This election is a C-Corp concept (tied to stock grants, not LLC membership interests).
Standard legal docs: The VC ecosystem runs on standardized legal documents (SAFE notes, Series A term sheets, NVCA templates) that are written for C-Corps. Using an LLC requires custom legal work that adds cost and complexity.
Employee stock options: Equity compensation for employees is straightforward with C-Corp stock options (ISOs and NSOs). LLC equity compensation (profits interests) is more complex to administer and less familiar to employees.
If you are going through YC, raising from a U.S. VC, or building for a traditional VC exit, form a Delaware C-Corp. There is no practical alternative.
| LLC | C-Corp | |
|---|---|---|
| Board of directors | Optional | Required |
| Annual shareholders meeting | Not required | Required |
| Corporate formalities | Minimal | Moderate (minutes, resolutions) |
| Equity classes | Flexible but complex | Standardized preferred/common |
| Employee stock options | Profits interests (complex) | ISOs/NSOs (standard) |
| VC compatibility | Limited | Universal |
| Annual compliance complexity | Lower | Moderate |
LLCs are operationally simpler. There is no requirement for a board of directors, formal shareholder meetings, or extensive corporate minute-keeping. For a solo founder running a service business or early-stage SaaS, this simplicity has real value.
C-Corps require more discipline around corporate formalities — maintaining a board, documenting decisions with resolutions, holding annual meetings. For a company with investors and employees, this structure is appropriate and expected. For a solo bootstrapper, it adds overhead with no benefit.

The "I'll convert later" argument:
Many founders start with an LLC and convert to a C-Corp when they are ready to raise. This is possible — Wyoming allows outgoing domestication, and Delaware allows incoming conversion — but it typically costs $1,000–$5,000 in legal fees and requires careful tax planning. If you are confident you will raise within 12–18 months, starting as a Delaware C-Corp saves you the conversion cost and potential tax complications.
If VC is more than 2 years away, start as an LLC. The annual cost savings and simplicity are worth it, and you have time to convert when the fundraising becomes real.
Converting an LLC to a C-Corp is a defined, documented process. The broad strokes:
The tax implications of conversion deserve particular attention. Converting an LLC to a C-Corp is treated as a deemed contribution of assets to a new corporation under IRS rules. If the LLC has significant appreciated assets or accumulated profits, there may be tax consequences. Consult a CPA before converting.
Bottom line: Default to LLC unless you have a specific, near-term reason to choose C-Corp. The pass-through taxation, operational simplicity, and lower annual costs make LLC the right starting point for the majority of international founders. Add the C-Corp complexity when — and only when — you need it.
