FlagSageCentre of vital interests
Glossary term
The centre of vital interests is the country with which a person's personal and economic relations are closer, a test used in tax treaty tie-breaker rules.
Tie-breaker rules in many tax treaties turn to the centre of vital interests when a person has a permanent home in both countries. HMRC guidance says the phrase covers social, domestic, financial, political and cultural links. The term keeps the spelling used in treaty texts.
The test weighs a person's whole situation, such as family, social life, work and financial links. No single fact settles it. If it cannot be determined, the next test in most treaties is habitual abode.
The test only applies inside a treaty, after both countries already treat the person as resident under their own laws. Wording varies between treaties, so read the specific treaty.
Not to be confused with
- Permanent home. The permanent home test comes first and asks only whether a home is available, while the centre of vital interests weighs a person's wider ties.
- Habitual abode. Habitual abode looks at where a person regularly lives and usually applies only if the centre of vital interests test does not give an answer.
