Delaware C Corp vs LLC for Foreign Founders

5 hours ago

7 min read

The choice between a Delaware C corp vs LLC decides how much US tax a non-US founder pays on profits, whether venture investors will sign a term sheet, and how cleanly the company can be sold. A Delaware C corp pays federal corporate income tax at 21% and withholds 30% on dividends to foreign shareholders unless a treaty lowers the rate. A Delaware LLC is by default not taxed at the entity level, but a foreign owner then faces US reporting duties and, if the business operates in the US, exposure to effectively connected income. This article compares both structures for founders based in the UK, the EU, the UAE and elsewhere, covering tax, fundraising, formalities and exit.

What Is the Difference Between a Delaware C Corp and an LLC?

Delaware C corp meaning

A C corp is a corporation taxed separately from its owners. Profits are taxed once at the company level under the federal 21% rate, and a second time when the company distributes dividends to shareholders. Shares, a board of directors and officers form the standard governance model, and Delaware's General Corporation Law is the body of rules that investors and their counsel know best.

Delaware LLC meaning

A limited liability company is a flexible entity governed by an operating agreement. With one owner it is by default a disregarded entity for US federal tax, and with two or more owners it is by default a partnership. The owners can also file Form 8832 to have the LLC taxed as a corporation, which is a route some founders use when they want LLC governance and corporate tax treatment together.

What Do VCs Expect From Foreign Founders?

Preferred stock and standard documents

US venture funds usually invest through preferred stock with liquidation preferences, anti-dilution terms and board seats, and the standard financing documents are written for corporations. Convertible notes and SAFEs are likewise drafted for C corps. An LLC can replicate some of these terms through a custom operating agreement, but each investor's counsel must then review a non-standard document, and many funds decline to do so. Our guide to Series A, B and C funding explains how these rounds are usually structured.

QSBS and the exit

Founders and early investors in a C corp may qualify for the qualified small business stock exclusion under Section 1202. For stock issued after July 4, 2025, the exclusion is 50%, 75% or 100% of the gain after three years, four years or five years or more of holding, with a cap of the greater of $15 million or ten times basis, and the issuer's gross assets must not exceed $75 million when the stock is issued. Whether a non-resident founder benefits depends on whether the US taxes the sale at all, which is covered below.

Converting an LLC to a C corp later

Many founders start with an LLC and convert once an investor appears. Delaware allows a statutory conversion, but the cost varies, and the conversion can trigger tax consequences in the founder's home country. Estimates in the market range from low four figures to tens of thousands of dollars, so a founder who expects to raise within a year often incorporates as a C corp from the start.

How Is a Delaware C Corp Taxed? 21% Tax, 30% Dividend Withholding and Treaty Relief

Corporate tax and dividends

The company pays 21% federal tax on its taxable income, plus any state tax where it operates. A dividend paid to a non-resident shareholder is US-source income subject to 30% withholding under the statutory rate, which a tax treaty can reduce. The shareholder must give the company a Form W-8BEN (or W-8BEN-E for an entity) to claim the reduced rate, and without it the company withholds the full 30%.

Treaty rates by founder residence

The table below shows the dividend rates for the residences most of our clients ask about. The treaty text and the IRS treaty tables control, and conditions such as ownership thresholds and limitation-on-benefits clauses apply.

Founder or holder	Dividend withholding on US-source dividends
UK resident individual	15% under the US-UK treaty
UK company holding at least 10% of the voting stock	5%
UK company holding at least 80% of the voting stock, subject to conditions	0%
UAE resident (individual or company)	30%, because no US-UAE income tax treaty is in force
EU resident	Depends on the treaty between the US and the founder's country of residence

Selling shares and the exit

A non-resident individual generally owes no US federal tax on gain from selling shares in a US corporation, unless the person spent 183 days or more in the US in that year or the corporation is a US real property holding company. The home country usually taxes the gain, and for founders in the UK or the EU the controlled foreign corporation rules can also reach profits kept inside a US company.

Why Can a Non-Resident Not Elect S Corp Status?

The shareholder rule

An S corporation passes income through to its shareholders and avoids the corporate-level tax, which is why US founders often use it. Section 1361(b)(1)(C) of the Internal Revenue Code prevents a corporation from qualifying as a small business corporation if any shareholder is a non-resident alien. If a non-resident acquires shares later, the S election terminates on that date, and the IRS grants relief for inadvertent terminations only through private rulings that bind just the taxpayer who applied.

What foreign founders use instead

A founder who wants a single level of tax has two practical options. The first is an LLC, as described below. The second is a C corp combined with a treaty rate and a home-country holding structure, which is common for UK and EU founders. Our overview of sole proprietorship, LLC or S corp for a US startup explains why S status is a US-resident option.

How Is a Foreign-Owned LLC Taxed?

Single-member LLC and Form 5472

A single-member LLC owned by a non-US person and not conducting business in the US generally has no US income tax liability. It still has to file Form 5472 with a pro forma Form 1120 each year, generally by April 15 for a calendar-year company, or by October 15 if an extension is filed on Form 7004, and the IRS assesses a $25,000 penalty for a missed or substantially incomplete filing. The forms are not sent to the address in the Form 1120 instructions: Foreign-owned U.S. DE is written across the top of the Form 1120, and the package is filed by fax or mail, with exceptions possible. Founders who register an LLC and then forget about it are the most common source of these penalties.

Multi-member LLC and ECI risk

An LLC with two or more owners is a partnership, which files Form 1065. If it conducts a US trade or business, each foreign partner's share of the profit is effectively connected income (ECI), and the partnership must withhold on that share under Section 1446 at 37% for non-corporate foreign partners and 21% for corporate ones, according to the IRS. Services performed in the US by the founders, a US office or US employees are typical ways a startup LLC ends up with ECI, and each foreign partner may then have to file a US return.

Home-country treatment

Countries treat a US LLC differently. Some regard it as transparent and tax the founder on profits as earned, while others treat it as a corporation, which can produce double taxation or a mismatch with the US view. A founder in the UK, the EU or the UAE should confirm the local classification before forming the LLC, and our tax consultation team handles this analysis.

What Formalities and Annual Costs Apply?

Bylaws, meetings and the stock ledger

A C corp needs bylaws, a board, stockholder consents or meetings, minutes and a stock ledger, and investors review these records during due diligence. Missing board approvals for option grants or share issuances are a frequent issue in a financing round. An LLC runs on an operating agreement and has fewer mandatory formalities, but the agreement should still set out profit splits, transfer restrictions and what happens if a member leaves.

Delaware annual taxes

A Delaware LLC pays a flat annual tax of $400, due June 1. A Delaware corporation files an annual report by March 1 with a $50 fee, and pays franchise tax calculated under either the authorized shares method (minimum $175) or the assumed par value capital method (minimum $400), and startups with a large number of authorized shares generally use the second one. Domestic Delaware companies are exempt from beneficial ownership reporting to FinCEN under the 2025 interim rule, which FinCEN made permanent in a final rule published on August 14, 2026 (Federal Register document 2026-16576). The Delaware company registration page lists the setup steps and fees.

Which Structure Fits Your Founder Profile?

Raising venture capital

A founder who plans a seed or Series A round with US or international funds should use a Delaware C corp. Investors expect preferred stock and standard documents, option plans are simpler, and QSBS is available.

Bootstrapped or consulting business

A founder who sells services or software to clients, funds the business from revenue and does not plan to raise capital can use a Delaware LLC. This works best when the work is done outside the US, so the LLC has no ECI, and when the home country treats the LLC as transparent.

Holding IP, a crypto project or a regional subsidiary

A founder who holds IP or runs a token project usually faces investor and regulatory scrutiny, and a C corp (or a corporate-taxed LLC) gives a cleaner cap table. In some cases, a non-US parent holds the US company as a subsidiary, which allows treaty planning for dividends.

Final Thoughts

A Delaware C corp fits a foreign founder who expects to raise venture capital or sell the company to a strategic buyer, and the cost is 21% corporate tax plus dividend withholding of 30% or the treaty rate. A Delaware LLC is lighter for a founder who runs the business from abroad without outside investors, as long as Form 5472 is filed every year and the home country's treatment of the LLC has been checked before formation. Founders who start with an LLC and later raise a round should budget for a conversion and plan the home-country tax result in advance.
