More and more companies are operating internationally and so are their workforces.
Some UK businesses may even choose to appoint directors who live overseas.
While international board appointments bring valuable expertise, they can cause unexpected UK tax liabilities and often double taxation.
If you are a non-UK resident director of a UK company, understanding how UK tax applies and how double tax treaties operate is crucial to avoid paying more tax than necessary.
Why does UK tax apply to non-UK directors?
Under UK tax law, directors are treated as employees for Income Tax purposes.
This means that remuneration connected to duties performed in the UK is generally subject to UK Income Tax, regardless of where the director lives or where payment is made.
If you attend board meetings, oversee UK operations, negotiate contracts or carry out other substantive duties physically in the UK, HMRC can tax the portion of your earnings attributable to those UK duties.
Remuneration may include:
- Salary and bonuses
- Directors’ fees
- Benefits in Kind
- Share-based awards
- Certain reimbursed expenses
The UK company may also have an obligation to operate PAYE on the UK portion of income, even if the director is paid by an overseas entity.
In addition, National Insurance Contributions (NICs) may apply. NICs are determined primarily by physical presence and social security agreements.
NICs are not based on tax residence or double tax treaties, which could mean liabilities can arise even when Income Tax relief is available.
What is the risk of double taxation?
Most countries tax their residents on worldwide income and a non-UK director may be taxable in their home country on the same income that is taxed in the UK.
Without the right relief, this can result in double taxation and paying twice on the same earnings.
This is where a Double Taxation Agreement (DTA) becomes crucial.
How do double tax treaties offer relief?
The UK has double tax treaties with more than 130 countries. These agreements allocate taxing rights between jurisdictions and provide support to prevent double taxation.
Treaties often include a specific director’s fees article, which commonly permits the UK to tax fees paid by a UK company.
However, depending on the nature of the role and remuneration structure, employment income provisions may also apply.
Where income is taxed in both countries, the director’s country of residence will usually provide relief by:
- Granting a foreign tax credit for UK pay
- Exempting the income from local taxation
The exact position depends on the wording of the relevant treaty.
How do you establish treaty residence?
If an individual is regarded as tax resident in two countries under domestic rules, they are considered dual resident.
In these cases, the treaty’s tie-breaker tests determine treaty residence.
The tests often consider:
- Where the individual has a permanent home
- Their centre of vital interests (economic and personal ties)
- Habitual residence
- Nationality
The country determined under these rules becomes the individual’s treaty residence, which then affects how taxing rights are allocated.
How can you claim treaty relief?
Relief is not automatic and directors may need to:
- File a UK Self-Assessment tax return
- Claim foreign tax credits in their home jurisdiction
- Submit HMRC forms such as Form DT-individual, if applicable
- Obtain a certificate of tax residence from their home tax authority
Where UK PAYE has been applied but treaty protection limits UK tax, a reclaim may be possible.
If the UK company bears the cost of remuneration, this can affect treaty outcomes and PAYE obligations.
