UK Taxes and Double Tax Treaties
UK Corporation Tax currently uses a 19% small-profits rate for qualifying profits up to GBP 50,000 and a 25% main rate above GBP 250,000, with marginal relief between them. Thresholds can be reduced for short accounting periods and associated companies. VAT, payroll and other taxes depend on what the company actually does.
A double-tax treaty does not make income tax-free. It allocates taxing rights and may reduce withholding on dividends, interest or royalties when residence, beneficial ownership, substance and procedural conditions are met. Permanent-establishment and management questions can matter when the founder works from another country.
Do not choose a company from a rate table alone. Map where decisions are made, where people work, where customers are served and how money moves, then compare the treaty text and domestic rules with a qualified adviser.
