UK Companies in International Tax Planning

UK companies have traditionally been widely used in international business due to the advantages offered by the jurisdiction, as well as the relatively straightforward requirements for company incorporation and functioning. In recent years, however, a number of legislative and regulatory changes have affected the corporate structures most commonly used in the UK.

This article provides an overview of the key features of the UK as a jurisdiction for company incorporation in light of these developments.

Why Choose a UK Company?

Setting up a company in the UK gives entrepreneurs access to a number of practical advantages when doing business internationally:

Advantage	Explanation
Well-established legal and judicial systems	The choice of English law and the jurisdiction of the English courts is common in international commercial contracts and corporate arrangements. This is largely attributable to the predictability of English law, its long-established body of case law, and the strong international reputation of the UK judicial system.
Wide range of corporate structures	The UK offers a wide range of corporate vehicles in different legal forms, with different liability regimes and governance structures, according to specific business objectives.
Lower barriers to company incorporation	It is possible to set up a company in the UK in one of its most common forms within a relatively short period of time. In addition, there is no minimum share capital requirement.
Flexible corporate governance	Members of UK companies enjoy considerable freedom in determining the management structure and allocating rights and responsibilities under the company’s constitutional documents.
Tax planning opportunities	Although the UK imposes relatively high corporate tax rates, its tax legislation provides different tax treatment depending on the type of a business entity.  In addition, the UK has one of the world’s most extensive networks of tax treaties, which can help reduce the overall tax burden.

The UK comprises several legal jurisdictions, each of which retains certain distinctive features of its civil and corporate law. As a result, company formation in Scotland may have some additional characteristics. However, the overall incorporation process broadly follows the same principles and rules as elsewhere in the UK.

UK Companies as Tax Planning Vehicles

In general, among the various legal forms of doing business in the UK, the following are the most common ones, including for tax planning purposes:

• Private Limited Companies (Ltd),
• Limited Liability Partnerships (LLP),
• Limited Partnerships (LP).

Private Limited Companies (Ltd)

The incorporation and further functioning of a private limited company (Ltd) are governed by the Companies Act 2006, as amended.

A private limited company has a relatively straightforward corporate structure:

• directors and shareholders may be of any nationality or residence;
• only one shareholder and one director are required; and
• as a general rule, the appointment of a company secretary is not required.

There is no minimum share capital requirement.

For tax purposes, a private limited company is generally treated as a UK tax resident. It is subject to UK corporate tax under the general rules (see the relevant section below) and must comply with the requirements regarding financial statements (see the relevant section below).

LLPs and LPs

UK partnerships are widely used for conducting business. English partnerships can be registered in the following legal forms:

• Limited Liability Partnerships (LLPs); and
• Limited Partnerships (LPs).

Unlike an LLP, a Limited Partnership does not have separate legal personality, with the exception of Scottish Limited Partnerships.

The legal status and liability of partners also differ between LLPs and LPs, as outlined below:

Partners in LLP	Partners in LP
The partners in an LLP have equal status. Their liability is limited to the value of their contributions.	An LP must have at least one general partner who exercises management and is liable for all debts and obligationsof the partnership. Limited partners contribute to the partnership’s capital, do not exercise management and are liable only to the value of their contributions.

Taxation of Private Limited Companies in the UK

The UK business tax system consists of the following main taxes:

Tax	Rates and Peculiarities of Application
Corporate tax	The applicable rate depends on the company’s taxable profits: profits exceeding GBP 250,000 – 25%; profits of GBP 50,000 or less – 19%; profits between GBP 50,000 and GBP 250,000 – marginal relief applies, providing for a gradual increase from the 19% rate to the main rate of 25%.
VAT	As a general rule, VAT registration is mandatory if: the taxable turnover for the previous 12 months exceeds GBP 90,000; or the taxable turnover is expected to exceed GBP 90,000 within the next 30 days. The standard VAT rate is 20%. Reduced rates of 5% and 0% apply to certain categories of goods and services.
Capital gains tax	As a general rule, capital gains are included in the company’s taxable profits and are subject to corporate tax at the applicable rate.
Withholding tax	Withholding tax generally applies to: interests – 20% (increasing to 22% from April 2027); and royalties – 20%. As a general rule, no withholding tax is imposed on dividends. These rates may be reduced under the applicable tax treaty of the UK.

Taxation of Partnerships in the UK

A common feature of UK partnerships is their tax treatment. Under UK tax law, both LLPs and LPs are treated as tax-transparent entities. In other words, as a general rule, a partnership is not regarded as a separate taxable person and, accordingly, cannot obtain a taxpayer number in the UK.

Instead, tax on the partnership’s profits is paid by its partners in their country of tax residence, in proportion to their respective interest in the partnership. Accordingly, the tax consequences for each partner must be assessed by reference to the legislation of the country or countries where the partners are tax residents.

However, in certain circumstances, the partners may also be liable to tax in the UK. This may be the case, for example, where:

• the partners are UK tax residents; or
• the partnership carries on business in the UK or derives income from UK sources.

In such cases, the partners are taxed in the UK at the applicable rates:

• companies are subject to corporate tax, depending on the amount of their taxable profits; and
• individuals are subject to income tax at rates ranging from 20% to 45%, depending on their taxable income.

Tax Reporting for Private Limited Companies and Partnerships in the UK

UK companies and partnerships are required to comply with corporate tax and VAT reporting obligations in accordance with the following rules.

Corporate Tax Returns

Companies must file a corporate tax return within 12 months after the end of each accounting period (which is generally the company’s financial year), even where no taxable profits have been generated or no tax is payable.

The deadline for paying corporate tax depends on the company’s level of taxable profits:

• taxable profits of no more than GBP 1.5 million – corporate tax must be paid no later than nine months and one day after the end of the relevant accounting period;
• taxable profits exceeding GBP 1.5 million – corporate tax is generally payable by quarterly instalments.

UK LPs and LLPs are required to file both:

• a partnership tax return on behalf of the partnership; and
• the relevant tax returns of the individual partners, reporting each partner’s share of the partnership’s profits (self-assessment tax return).

Partnership tax returns and the corresponding tax returns of the partners must be filed by 31 October (if submitted in paper) or by 31 January (if submitted electronically) of the year following the relevant tax year.

In the UK, the tax year runs from 6 April to 5 April of the following calendar year. However, a company may choose its own accounting period, which is commonly aligned with the date of incorporation.

Where tax is payable in the UK, it is generally due as follows:

• individual partners – by 31 January of the year following the relevant tax year; and
• corporate partners – in accordance with the applicable deadlines for corporate tax payment.

VAT Returns

Companies and partnerships registered for VAT are generally required to file VAT Returns on a quarterly basis, even where no VAT is payable or refundable for the relevant period.

VAT Returns must generally be filed within one calendar month and seven days after the end of the relevant VAT accounting period, which is typically three months. Businesses with taxable turnover of GBP 1.35 million or less may opt to file VAT returns annually rather than quarterly.

Financial Statements and Audit for UK Companies

Private Limited Companies

All UK companies are required to maintain accounting records and retain them either at their registered office or at such other location as the directors may determine for at least three years. Based on these accounting records, all companies, including dormant companies, must prepare and file annual financial statements.

Annual financial statements must be filed with Companies House within nine months after the end of the company’s accounting period, which is typically 12 months.

A company’s first accounting period begins on the incorporation date and ends on the last day of the month in which the first anniversary of the company’s incorporation falls. For example, if a company is incorporated on 17 October 2025, its first accounting period will end on 31 October 2026. Each subsequent accounting period will normally cover 12 months, running from 1 November to 31 October.

Components of financial statements depend on the size of a company:

Company Category	Financial Statements Required
Small companies, i.e. companies meeting at least two of the following criteria: annual turnover of no more than GBP 15 million; total assets of no more than GBP 7.5 million; or no more than 50 employees.	balance sheet; profit and loss account; and notes to the financial statements
Micro-entities, i.e. companies meeting at least two of the following criteria: annual turnover of no more than GBP 1 million; total assets of no more than GBP 500,000; or no more than 10 employees.	a simplified balance sheet

As a general rule, a company’s annual financial statements are subject to audit. The following companies are exempt from the statutory audit requirement:

• small companies; and
• micro-entities.

English and Scottish Partnerships

LLPs are subject to broadly the same requirements as Ltd companies in relation to accounting records, financial reporting, and audit obligations. In particular, LLPs must:

• maintain accounting records;
• file financial statements with Companies House within the same deadlines as companies; and
• have their financial statements audited, unless they qualify as small companies or micro-entities (the same thresholds apply).

Different rules apply to English and Scottish LPs. The obligation to prepare financial statements applies only to qualifying partnerships. An LP is treated as a qualifying partnership where each of its general partners is either:

• a limited liability company; or
• another entity whose members are themselves limited liability companies.

Qualifying partnerships shall prepare financial statements and, where applicable, have them audited in accordance with the same rules and within the same deadlines as private limited companies.

The requirements to submit financial statements also depend on the status of the LP’s general partners. Where the general partner is a non-UK company, the partnership is generally not required to file its financial statements with Companies House. In such cases, however, the financial statements must be made available in the UK upon request from interested parties.

Confirmation Statement for Companies and LLPs

In addition to their tax and financial reporting obligations, UK companies and LLPs are required to file an annual confirmation statement with Companies House. The sole purpose of this document is to confirm that the information already held by Companies House in respect of the company, LLP or Scottish LP is accurate and up to date.

A confirmation statement must be filed within 14 days after the end of each review period. The first review period begins on the date of incorporation and lasts for 12 months, with each subsequent review period also covering 12 months.

A confirmation statement includes, among other things, information on:

• the registered office;
• directors and a company secretary (if the latter has been appointed), or designated members (in the case of an LLP);
• persons with significant control;
• shareholders and share capital, or members (in the case of an LLP);
• Standard Industrial Classification (SIC) codes; and
• other prescribed information.

All Ltd companies and LLPs, including dormant entities, are required to file a confirmation statement. This requirement does not currently apply to LPs, with the exception of Scottish LPs.

Information on Beneficial Owners, Directors and Shareholders of UK Companies

UK law requires certain entities to maintain a Register of People with Significant Control (PSC Register), which broadly corresponds to a beneficial ownership register in other jurisdictions. This requirement applies, among others, to:

• Ltd companies;
• LLPs; and
• Scottish LPs.

This requirement does not apply to LPs registered in other parts of the United Kingdom.

Information on PSCs must be filed with Companies House. Most information relating to PSCs is publicly available, with the exception of:

• their habitual residential address; and
• their full date of birth (only the month and year are publicly disclosed).

In certain circumstances, however, a PSC may apply for additional protection of their personal information.

Since 18 November 2025, companies have no longer been required to maintain their own internal registers of directors, company secretaries, or PSCs. Instead, this information is filed directly with Companies House and kept up to date in the official register.

That said, companies are still required to maintain a register of members at their registered office and to make it available for public inspection in accordance with the applicable legal requirements.

Accordingly, information relating to a company’s directors and PSCs becomes publicly available automatically through the Companies House register, whereas the register of members is not published online but must be made available for inspection upon request.

In addition, since 18 November 2025, there is a requirement to verify the identity of directors and PSCs of UK companies, regardless of their place of residence. Similar identity verification requirements are expected to be introduced in due course for corporate members of LLPs, persons associated with LPs, and some other categories of persons.

Common Uses of UK Companies

UK companies and partnerships may be used as part of a broader international business structure, including structures that involve entities incorporated in other jurisdictions. Set out below are some common examples of how UK entities may be used.

UK Company Acting as an Agent

A UK company may act as an agent under an agency agreement, entering into transactions in its own name but on behalf of a principal, whether located in the UK or abroad. In such a case, only the agency commission (or other remuneration) actually received by the agent is generally subject to corporate tax in the UK.

In this respect, the following considerations are particularly important:

• the agency agreement must accurately reflect the actual commercial relationship between the parties;
• the agent must act as an independent intermediary rather than as a vehicle established for the artificial reallocation of profits; and
• the agent’s remuneration must reflect market conditions.

UK Holding Companies

A UK company is frequently used as a holding company owning shares in subsidiaries incorporated in foreign jurisdictions. To use a UK company as a holding company efficiently, it is necessary for the United Kingdom to have a double tax agreement (DTA) with the jurisdiction where the subsidiary is incorporated.

It is important to note, however, that the benefits of DTAs are generally available only if the following conditions are satisfied. In particular:

• the company claiming treaty benefits must be the beneficial owner of the income rather than a mere nominee or conduit entity;
• the company shall have sufficient economic substance in the UK, including, for example, real business premises and effective management exercised from the UK territory; and
• DTAs generally do not apply to dormant companies, as a company that is formally inactive cannot, in principle, be regarded as the recipient of income for treaty purposes.

In addition, UK tax legislation exempts a substantial proportion of dividend income received by UK companies from both UK and foreign subsidiaries from UK corporate tax.

The specific conditions of the exemption depend on the size of the recipient company and its ownership structure. In practice, however, most dividends qualify for the exemption, provided that the distribution does not form part of arrangements designed primarily to obtain a tax advantage.

In addition, to claim the exemption or any other treaty benefits available under an applicable DTA, the company must obtain a UK tax residence certificate.

In certain cases, dividends received are subject to corporate tax; however, a foreign tax credit method may be applied. According to this mechanism, the withholding tax paid in the subsidiary’s jurisdiction may be credited against the corporate tax calculated and paid in the UK.

International Trade

A UK company may act as the contracting party in international sale and purchase transactions involving counterparties in different jurisdictions, including transit trade arrangements where it is not involved in the movement of the goods.

In such cases, the company is subject to UK corporate tax under the general rules, with tax being charged on the trading profit, i.e. the difference between the purchase price and the sale price.

Management

International groups of companies frequently use UK companies as regional administrative or management centres to:

• coordinate the activities of subsidiaries;
• centralise management and decision-making; or
• provide management services to other companies within the group.

Fees received for such services are subject to UK corporate tax.

Provision of Services

UK companies may also be used to provide a wide range of services, including:

• marketing and promotional services;
• accounting services;
• recruitment and staffing services;
• freight forwarding and logistics services; and
• other commercial services.

Income derived from the provision of such services is subject to UK corporate tax under the ordinary rules.

What to Consider When Choosing UK Companies?

The United Kingdom combines a relatively straightforward incorporation procedure with a well-established legal and judicial system. It also offers a wide range of legal forms and a flexible tax regime.

However, selecting the most appropriate structure (Ltd, LLP, English LP or Scottish LP), as well as the ways in which such structures are used, requires more than an assessment of the potential tax implications. It is equally important to consider other related obligations.

In practice, the main obligations include:

• timely preparation and filing of financial, tax and corporate reports; and
• ensuring the transparency of the company’s or partnership’s structure in dealings with the regulatory authorities.

Overall, UK companies and partnerships continue to represent one of the most widely used and attractive vehicles for structuring international business operations.
