UK company formation: choose a Ltd or LLP for the business model, not the shortcut.
The UK remains fast to incorporate, globally recognisable and commercially credible. A Ltd does not always pay 19%, and a tax-transparent LLP does not automatically mean 0%. Profits, members, activity, residence and effective management drive the result.
Fast to incorporate. Harder to structure correctly.
Ltd: one shareholder can also be the sole director; directors do not need to live in the UK. The company needs an appropriate physical UK registered office. Since November 2025, Companies House identity verification is a legal requirement for directors and PSCs under the applicable timetable.
Opaque company
The company pays Corporation Tax. Often fits trading, reinvestment, hiring and investors.
Tax transparency
Normally treated as a partnership for UK direct tax, allocating profits to members. At least two designated members are required.
Holding / expansion
The UK can work for groups and investment, but treaty, management, anti-hybrid and CFC rules matter.
“A UK Ltd always pays 19%.”
“A non-resident LLP is automatically 0%.”
“Companies House prevents home-country taxation.”
“A virtual office proves substance and management.”
19% is the small-profits rate; 25% is the main rate with marginal relief between thresholds.
An LLP is normally transparent; members need their own residence/source analysis.
A home country can treat a UK company as resident where effective management occurs.
Registered office and filings are compliance, not economic substance.
| Area | Current rule | Watch |
|---|---|---|
| Corporation Tax | 19% ≤ £50,000; 25% > £250,000; marginal relief in between. | Associated companies can reduce thresholds. |
| VAT | 20% standard; general registration threshold £90,000 taxable turnover. | NETP rules may differ. |
| Annual accounts | Usually 9 months after year-end. | Special rules for first accounts. |
| Corporation Tax / CT600 | Payment usually 9 months + 1 day; return 12 months. | Large companies may pay by instalments. |
| Confirmation statement | Periodic Companies House filing. | Registered email and identity requirements apply. |
| Identity verification | Legal requirement since 18 Nov 2025. | Directors and PSCs according to timetable. |
| Registered office | Physical appropriate UK address. | Standalone PO Box is insufficient. |
| Banking / KYC | Company number does not guarantee banking. | UBO, residence, activity and source of funds. |
Companies House 2026: identity verification is now a legal compliance layer, not optional KYC.
International business valuing a recognised common-law vehicle.
Company serving UK/global clients.
Founder reinvesting or planning investors/shareholders.
Genuine LLP with two or more members where transparency works in their residence countries.
Founder expecting to erase home-country tax by invoicing through a Ltd.
LLP with nominal members created only for a supposed 0%.
Company managed entirely abroad without effective-management analysis.
Structure chosen only because incorporation is quick.
Incorporation is not management.
A home country can treat a UK company as resident where effective management is exercised there. For Spain, the treaty deems a dual-resident non-individual resident where its place of effective management is situated.
The UK–Spain treaty entered into force on 12 June 2014 and has been modified by the MLI, with relevant effects from 2023. It helps with double taxation and PE questions, but it does not make an artificial structure defensible.

UK Ltd and LLP questions worth answering before formation.
Can a non-UK resident form a UK Ltd?
Yes. Directors do not have to live in the UK, but the company needs an appropriate UK registered office and must meet Companies House and HMRC obligations.
What Corporation Tax does a UK Ltd pay in 2026?
19% at £50,000 or less; 25% above £250,000, with marginal relief in between and threshold adjustments for associated companies/short periods.
Ltd or LLP?
A Ltd is subject to Corporation Tax. An LLP is normally transparent for UK direct tax, allocating profits to members.
Is a non-resident LLP automatically tax-free?
No. Source, UK activity and each member’s residence/tax position must be analysed.
Does an LLP need two members?
It must maintain at least two designated members.
What is the VAT threshold?
The general threshold is £90,000; non-established businesses can face different rules.
What changed at Companies House?
Identity verification became a legal requirement from 18 November 2025 for directors and PSCs under the applicable timetable.
When are filings due?
Accounts usually 9 months; Corporation Tax 9 months + 1 day; Company Tax Return 12 months.
Can I manage a UK company from Spain or elsewhere?
Yes operationally, but this can create corporate residence, PE, CFC or other exposure there.
Does incorporation guarantee banking?
No. Banks and fintechs apply their own KYC.
