Corporation Tax for Non-Resident
Corporation Tax is one of the most important ongoing tax obligations for any UK limited company, and for non-resident owners, it comes with specific considerations that don’t apply to UK-resident owners. Understanding the current rates, how the CT600 return works, when payments are due, and critically, how UK tax residency of the company interacts with your personal tax residency in another country, is essential for compliant operation. Get it right and you’re set up for tax-efficient trading. Get it wrong and you can face penalties, back tax, and unexpected liabilities. At Form My Company, we’re an Authorised Corporate Service Provider (ACSP) handling UK company formation and Companies House compliance. For Corporation Tax specifically, we work alongside qualified UK accountants who handle the ongoing filing and tax planning. This guide explains everything non-resident owners need to know about Corporation Tax for their UK company in 2026.
What Is UK Corporation Tax?
Corporation Tax is the primary tax on UK company profits. It applies to:
UK limited companies. Whether owned by UK residents or non-residents.
UK LLPs. Different rules apply, but similar principles.
Foreign companies with UK activities. Under specific rules for permanent establishments.
Profits from UK trading activity. Regardless of where the owner lives.
Investment income. Where earned in the UK.
Chargeable gains. From disposal of UK business assets.
The company itself pays Corporation Tax on its profits, separate from the personal tax that owners or directors pay on money they extract from the company.
Current UK Corporation Tax Rates
From April 2023, UK Corporation Tax rates are:
Small profits rate. 19% on profits up to £50,000.
Main rate. 25% on profits over £250,000.
Marginal relief. For profits between £50,000 and £250,000, effective rate gradually increases from 19% to 25%.
Effective rate for £100,000 profits. Approximately 22.5%.
Effective rate for £150,000 profits. Approximately 23.75%.
Effective rate for £200,000 profits. Approximately 24.5%.
These rates apply to profits chargeable to Corporation Tax, which is broadly profits minus deductible expenses.
UK Tax Residency of the Company
For non-resident owners, the fundamental question is where the company itself is tax resident:
Companies incorporated in the UK. Are generally UK tax resident.
Central management and control. UK companies managed from abroad may still be UK tax resident under this concept.
Overseas incorporation. Companies incorporated abroad but managed in the UK can also be UK tax resident.
UK tax residence for corporations. Different from personal tax residency rules.
Double tax treaties. May affect where a company is treated as tax resident.
Impact on Corporation Tax. UK tax resident companies pay Corporation Tax on worldwide profits.
Impact on non-resident owners. Doesn’t change the company’s UK tax residence.
Ongoing implications. For strategic tax planning.
For most non-resident-owned UK limited companies formed and operating in the UK, the company is UK tax resident regardless of where the owners live. This means the company pays UK Corporation Tax on its worldwide profits.
Central Management and Control
The concept of central management and control matters:
Established through case law. UK courts have developed the concept over decades.
Where decisions are made. The location of strategic decision-making determines management and control.
Board of directors. Where directors typically meet and make decisions.
Substantive control. The person or people actually making decisions, not just formal role holders.
Non-resident directors. Can affect where central management and control sits.
Multiple factors considered. Not just formal board meeting location.
Ongoing importance. For maintaining UK tax residence.
Documentation matters. Records of board decisions and meetings.
Board meetings. Where held affects central management and control.
Video conferencing. Considered acceptable for maintaining central management and control.
For non-resident-owned UK companies, having genuine central management and control involves careful attention to how strategic decisions are made and documented.
Permanent Establishment Considerations
Beyond company tax residency, permanent establishment matters:
Permanent establishment defined. A fixed place of business in a country.
UK permanent establishment. UK offices, factories, warehouses of an overseas company.
Warehouse consideration. Storing goods in the UK (like Amazon FBA warehouses) can create permanent establishment issues.
Agent-based establishment. Where UK-based agents habitually conclude contracts.
Preparatory activities. Some activities don’t create permanent establishment.
Double tax treaty definitions. Vary by specific treaty.
Tax implications. Permanent establishments are taxed in the country they’re located.
Non-resident companies with UK PE. Pay UK Corporation Tax on profits attributable to the UK activities.
Filing obligations. Beyond just profits tax.
Understanding whether your business creates a permanent establishment in the UK matters for cross-border tax planning.
The Corporation Tax Return (CT600)
Every UK-tax-resident company must file an annual Corporation Tax return:
Form CT600. The Corporation Tax return.
Accounting period. Usually 12 months, aligning with your accounting reference date.

What Goes Into a Corporation Tax Calculation
The Corporation Tax calculation:
Start with accounting profit. From your statutory accounts.
Add back disallowable expenses. Client entertainment, some depreciation, private-use costs, etc.
Deduct capital allowances. For business equipment, plant, machinery.
Adjust for other tax rules. Various.
Arrive at taxable profit. The figure that Corporation Tax applies to.
Apply Corporation Tax rate. Based on taxable profit.
