International Tax FAQs

What is a double taxation agreement?

DTAs are treaties between two countries that determine which country has the right to tax specific types of income and provide relief from double taxation. The UK has one of the world's largest DTA networks, covering over 130 countries.

When does a foreign company have a UK tax presence?

A foreign company may have a UK permanent establishment (and UK Corporation Tax obligations) if it has a fixed place of business in the UK, a dependent agent who habitually concludes contracts, or if its central management and control is exercised from the UK.

How does transfer pricing work?

Transfer pricing rules require transactions between connected parties in different countries to be priced at arm's length — as if the parties were independent. UK rules apply to medium and large enterprises and require documentation supporting the pricing methodology used.
