-
✓
VC Standard: Over 90% of US venture-backed startups are Delaware C-Corps. If you plan to raise from US or international VCs, Delaware is effectively mandatory. Investors have standardized term sheets, board structures, and preferred stock provisions all built around Delaware law.
-
✓
Court of Chancery: Delaware's dedicated business court (no jury trials) provides predictable, sophisticated corporate law rulings. Over 200 years of case law means virtually every corporate governance question has been answered, reducing legal uncertainty for founders and investors alike.
-
✓
QSBS Tax Exemption: Qualified Small Business Stock (Section 1202) allows US investors to exclude up to $10 million in capital gains from federal tax. This is a massive incentive for angel investors and VCs — and it requires a C-Corp. Your UK Ltd cannot offer this benefit.
-
✓
No Residency Requirement: Delaware does not require directors, officers, or shareholders to be US residents. You can form, own, and operate your C-Corp entirely from the UK. No SSN or US address is needed for incorporation or EIN.

Frequently Asked Questions
Can I form a Delaware C-Corp from the UK without visiting the US?
Yes, the entire process can be completed remotely from the UK. You can file your Certificate of Incorporation online through the Delaware Division of Corporations or use a registered agent service. The EIN can be obtained by fax or phone. US bank accounts can be opened remotely with Mercury, Relay, or other fintech-friendly banks. Many UK founders never visit the US until well after their company is operational.
Do I need to close my UK Ltd to form a Delaware C-Corp?
No. Many UK founders maintain both entities. Common structures include: (1) keeping the UK Ltd as a parent holding company that owns the Delaware C-Corp, (2) running both as separate operating entities for different markets, or (3) making the UK Ltd dormant while operating through the Delaware C-Corp. The right structure depends on your investor plans, where your team is located, and tax considerations. See my UK Ltd vs US C-Corp comparison for detailed guidance.
How much does it cost to incorporate a Delaware C-Corp from the UK?
The minimum cost is approximately $150-$250, broken down as: Delaware filing fee ($89), registered agent ($49-$149/year), and the EIN application is free. If you use Stripe Atlas, the flat fee is $500 which includes the filing, registered agent for year one, and some banking setup. Ongoing annual costs include the Delaware franchise tax ($400 minimum) and registered agent renewal. See my Stripe Atlas vs Direct comparison for a full cost breakdown.
Will I need to pay US taxes on my UK income?
Your Delaware C-Corp will pay US federal corporate tax (21%) on its US-sourced income and income effectively connected with a US trade or business. As a UK tax resident who is not a US person, you personally are not subject to US income tax on your worldwide income. The UK-US Tax Treaty provides mechanisms to avoid double taxation, including foreign tax credits. You will still need to report your US company ownership to HMRC. See my UK-US Tax Treaty guide and HMRC Reporting guide for details.
Do US VCs actually require a Delaware C-Corp?
In practice, yes. While there is no legal requirement, the overwhelming majority of US venture capital firms will only invest in Delaware C-Corps. Their standard term sheets, preferred stock provisions, protective provisions, and board structures are all built around the Delaware General Corporation Law (DGCL). Attempting to raise US VC funding through a UK Ltd would require custom legal work that most investors will not undertake. Y Combinator, Techstars, and virtually all major accelerators also require Delaware C-Corp incorporation. See my VC Fundraising guide for more.
