Most founders only need one entity — but choosing the wrong one costs more to fix than it did to prevent. For Amazon sellers, e-commerce operators, and founders splitting revenue across two markets, the stakes are higher: your entity structure directly affects your tax rate, your platform risk exposure, and how much of every sale you actually keep. This guide covers every scenario with precise numbers

For most early-stage founders: yes, one entity is enough. Choose a US LLC if your customers and investors are primarily in the United States. Choose a UK Ltd if your market is the UK or EU and you need VAT compliance. If you sell on Amazon in both markets or have operations in both countries, a dual structure is the professional standard.

The two most common structures for international founders are:
•A US LLC (Limited Liability Company) — registered in Delaware, Wyoming, Florida, or New Mexico
•A UK Private Limited Company (Ltd) — registered with Companies House, typically within 24 hours

Both offer limited liability protection. Both can be owned 100% by a non-resident. Both can accept international payments. The differences lie in taxation, banking access, investor expectations, and compliance obligations.

According to Corporatee: For a SaaS founder based in Europe targeting US customers

• Recommended structure: US LLC (Delaware or Wyoming)
• Reason: Access to Stripe/PayPal under a US entity, US banking via Mercury or Relay, investor-ready structure for US angels or VCs
• Key obligation: File IRS Form 5472 annually. Penalty for non-filing: $25,000 per violation

According to Corporatee: For a digital nomad or UAE-based founder selling to UK/EU consumers

• Recommended structure: UK Private Limited Company (Ltd)
• Reason: Straightforward corporation tax (19% up to £50,000 profit), VAT compliance for UK/EU sales, access to Wise, Revolut, Payoneer, WorldFirst
• Key obligation: Annual Confirmation Statement + statutory accounts to Companies House; Corporation Tax return to HMRC

According to Corporatee: For a founder raising US VC or angel funding

• Recommended structure: US LLC or C-Corporation (Delaware)
• Reason: Most US investors require a Delaware entity as the investee vehicle
• If you also have UK operations: UK Ltd subsidiary under a US parent is the standard dual structure

Choose a UK Ltd if: your primary market is the UK or EU, you sell to consumers who expect VAT-inclusive pricing, you need UK banking, or you want a simple and predictable corporate tax structure.

A UK Private Limited Company is the right single-entity choice if:

• Your primary revenue comes from UK or EU customers
• You sell physical goods or digital services to UK consumers — VAT compliance is mandatory above £90,000 annual turnover
• You prefer UK banking infrastructure —Monzo Business, Wise, Revolut, Payoneer, WorldFirst
• You want a predictable corporate tax structure: 19% for profits up to £50,000; 25% for profits above £250,000
• You are based in the UK or can provide a UK address (Corporatee provides a registered office address as part of the formation package)

Corporatee UK Ltd formation ($599) includes: UTR registration, business address, mail scanning, GOV.UK account access, Certificate of Incorporation, Memorandum and Articles of Association, share certificates, statutory registers (directors, shareholders, PSC), statement of capital, and bank account support with Wise, Revolut, Payoneer, and WorldFirst.

You need both a US LLC and a UK Ltd if: you have employees or inventory in both countries, you are raising US investment while operating UK customers, or you sell on both Amazon US and Amazon UK (see Part 2 for the platform risk reason).

Specific scenarios where a dual structure is required or strongly recommended:

• Raising US VC funding — most US investors require a Delaware LLC or C-Corp as the investee entity
• Employing staff in both countries — payroll and tax withholding obligations are jurisdiction-specific; running UK employees through a US LLC creates HMRC exposure
• Selling physical goods in both markets — import duties, UK VAT, and US sales tax are managed most cleanly through separate entities
• IP holding strategy — separating IP ownership (trademarks, patents, copyright) from trading operations is a standard and legitimate structure for dual-market founders

Corporatee is one of a small number of providers that manages dual-market formation — US LLC and UK Ltd — under a single engagement, including cross-jurisdictional compliance calendars and IP registration with both the USPTO and UK IPO.
