Which of the following is NOT a type of residency in the UK?

In the context of UK residency, the terms used typically refer to established categories that pertain to an individual's tax status and length of stay in the country. The selection "voluntary non-resident" is not a recognized category of residency under UK tax laws.

Instead, the established terms include "automatic resident," which applies to those who meet specific criteria for residency based on their presence in the UK; "sufficient UK ties," which refers to individuals who do not automatically qualify as residents but have enough ties to the UK that may lead to residency status; and "automatic non-resident," which is designated for those who do not meet the residency criteria and are absent from the UK for a sufficient amount of time.

Thus, the option regarding "voluntary non-resident" is the correct response as it does not correspond to an official categorization used in the determination of residency in the UK. Understanding these classifications is essential for determining an individual's tax obligations and residency status within the UK framework.
