The issue of corporate tax residency is crucial for entrepreneurs deciding to establish a company abroad, particularly in the United Kingdom. A company’s tax residency determines the jurisdiction in which the company must pay tax on its entire income, regardless of where the income was actually generated.
In the UK, a company’s tax residency is determined by two main criteria: formal (legal) and economic (effective management).
Formal Criterion: According to UK law, any company registered in the United Kingdom is automatically considered a tax resident of the country. This means the company is subject to full tax liability in the UK on all its income, irrespective of the income’s source.
Economic Criterion: Equally important is the economic criterion, known as the “place of effective management”. This criterion arises from both UK domestic regulations and international double taxation treaties. The “place of effective management” refers to the location where key managerial and commercial decisions concerning the company’s operations are made. These decisions must significantly impact the company’s operations and business strategy. In practice, this is typically where the highest-ranking individuals managing the company—such as board members or senior executives—are located.
It is worth noting that a company may have more than one location where management occurs, but only one “place of effective management” for tax purposes. For instance, even if the directors of a company reside outside the UK, the company could still be treated as a UK tax resident. This situation might arise if there is no clear alternative location of effective management or if key board meetings are held remotely (e.g., via videoconference) and at least one decision-maker is physically present in the UK.
Double Taxation Treaties: Internationally, double taxation treaties (DTTs) are crucial agreements that the UK has established with many countries. The purpose of these treaties is to prevent the same income from being taxed in two different jurisdictions. According to these treaties, if a company is deemed a tax resident in both states, the decisive factor is the place of effective management. Thus, if key decisions relating to the company’s activities are made in the UK, the company will be considered a tax resident there.
Certificate of Tax Residency: To formally confirm its tax residency status in the UK, a company can apply for a tax residency certificate issued by HM Revenue & Customs (HMRC). This certificate is often required by foreign business partners or overseas tax authorities to apply preferential tax rates available under double taxation treaties. The application to HMRC must include relevant evidence confirming the company’s UK tax residency.
Permanent Establishment: Another significant concept regarding tax residency is “permanent establishment”. This term refers to a fixed place through which a company conducts business activities in another country, such as a branch office, office premises, factory, or construction site lasting more than 12 months. If a company has a permanent establishment abroad, income attributed to that establishment will be taxable in that country according to the applicable double taxation treaty provisions.
Notably, a location maintained solely for preparatory or auxiliary activities, such as storing or delivering goods, purchasing goods, or collecting information, does not constitute a permanent establishment. Importantly, any individual acting on behalf of the company who habitually exercises authority to conclude contracts in the company’s name is also treated as constituting a permanent establishment unless their activities are limited to preparatory or auxiliary roles.
Profits generated by a permanent establishment are taxed in the country where the establishment is located, rather than in the country where the company itself is registered.
