Non-domicile, or non-dom, is a British tax status that allows a person who was born in another country, or if their parent is from another country, to pay tax in the UK only on their UK income. A person with non-dom status is someone who lives in the UK and is tax resident here, but who has their permanent home outside the country. Non-doms pay UK tax to the UK government like all other UK residents, but they only pay tax on money earned in the UK and do not have to pay any tax to the UK on money made elsewhere in the world unless they bring their money into the UK or deposit it into a UK bank account. However, non-doms do still have to pay tax on money earned within the UK. Non-dom status has been available since the French revolution and has allowed wealthy foreign immigrants to enjoy all the benefits of living in the UK while paying very little in UK taxes because they make the bulk, if not all, of their income abroad. The only reason for people to claim non-dom status as opposed to being an ordinary British tax resident is if they calculate that they will end up paying less tax on their worldwide income. If a person chooses not to pay tax in the UK on their overseas earnings, they must pay a substantial annual charge. In 2017, the non-dom rules were changed, and a person can no longer claim this status if they have been a UK resident for 15 years or more.
