Company registration, taxes and founder visas in United Kingdom
Checked against official sources on October 27, 2026. These national rules apply in every city in United Kingdom.
How do you register a company in the United Kingdom?
- Startups use a private company limited by shares, registered with Companies House (GOV.UK).
- Online registration costs £100, and most companies are registered within 24 hours. The paper form IN01 costs £124 and takes about 8 to 10 days.
- Directors verify their identity through GOV.UK One Login and register with the personal code they get. You also name who owns or controls the company, such as anyone holding more than 25% of the shares.
- The same registration sets the company up for Corporation Tax with HMRC, unless it is dormant. VAT registration becomes compulsory once taxable turnover passes £90,000 in 12 months (GOV.UK).
What taxes does a startup pay in the United Kingdom in 2026?
- Corporation tax: 19% on profits up to £50,000, 25% on profits above £250,000, and marginal relief in between. Both thresholds shrink for short accounting periods and associated companies (GOV.UK).
- VAT: 20% standard rate, 5% reduced rate (GOV.UK).
- R&D relief: the merged R&D expenditure credit pays 20% of qualifying spend. Loss-making SMEs that spend at least 30% of total costs on R&D can claim an extra 86% deduction and a payable credit worth up to 14.5% of the surrenderable loss (GOV.UK).
- Investor reliefs: SEIS and EIS make your shares cheaper for angel investors. From April 6, 2026, EIS lets a company raise up to £10 million a year (£20 million if knowledge-intensive) (GOV.UK).
- For 2027: the government’s corporate tax plan caps the main rate at 25% for this Parliament and keeps the 19% small profits rate and marginal relief.
Which visa can a foreign founder use in the United Kingdom?
The Innovator Founder visa is the UK’s founder visa:
- An approved endorsing body must confirm that your business idea is new, original, viable and able to grow. Endorsement costs £1,000, plus £500 for each progress check-in, with at least two (after 12 and 24 months).
- The visa fee is £1,357 from outside the UK or £1,693 to switch inside the UK, plus the healthcare surcharge of £1,035 a year (GOV.UK).
- You need English at B2 level and at least £1,270 in your bank account for 28 consecutive days.
- The visa lasts 3 years, can be extended with a new endorsement, and can lead to settlement after 3 years.
