Four facts decide your structure: where you are tax resident, where your customers are, whether you will raise US venture capital, and which banks accept your country. Founders raising from US investors need a Delaware C corporation. UK residents serving UK or EU customers usually belong in a UK limited company. Non-residents selling globally who need US Stripe usually form a US single-member LLC, commonly in Wyoming.
Answer five questions to compare a practical starting structure—US LLC, Delaware C corporation, UK Ltd, or a local company.
What actually drives the choice
Four things decide the structure more than filing price: where you live and manage the company, where your customers are, whether you will raise venture capital, and your banking and payment eligibility. Investors expect a Delaware C corporation; a UK resident usually belongs in a UK Ltd; a non-resident chasing US Stripe usually lands on a US LLC.
Whatever this tool suggests, confirm the home-country tax treatment before you form - the same entity can be taxed very differently depending on where you are resident.
