INTM332620 - Double Taxation applications & claims: permanent establishment and special relationship: When you have to consider PE
You will usually only have to consider this condition for relief in the following types of cases
- claims on an individual claim form where the claimant has answered ‘yes’ to the question about carrying on a ‘trade or business in the UK’. The most common type will be claims by Lloyds Underwriters
- claims by companies where they answer ‘yes’ to the question about being engaged in trade or business in the UK.
In the majority of cases where PE is a condition for relief this information will be given to you by the relevant HMRC office in answer to various questions (on forms in 4450/FD series) you need to ask as part of the examination process. There is a separate Article (usually Article 5 in the more modern DTAs) in the DTA which defines Permanent Establishment.
