Am I non-UK domiciled (non-dom)?

Many foreign nationals living in the UK have non-UK domicile (“non-dom”) status for tax purposes.  In the right circumstances non-dom status is advantageous for UK taxpayers.

In particular, a non-dom is able to claim the “remittance basis” of taxation.  Overseas income and gains are then only taxed if they are “remitted” to the UK.  “Remitted” here includes most ways in which foreign income or gains are brought to, used in or received in the UK.

In addition a non-dom expatriate employee is able to shelter non UK workdays from UK tax in the first three years they reside in the UK.  This is a valuable tax relief and requires careful planning.

Claiming the remittance basis results in the loss of certain tax allowances, but these are often not relevant to a non-dom’s situation.  Therefore, with careful planning, non-dom status can often protect foreign income and gains from UK tax.


  • For non-doms who have been resident in the UK in at least 7 out of the last 9 tax years, a £30,000 “remittance basis charge” is payable to access the remittance basis.
  • This charge increases to £60,000 for non-doms who have been UK resident in some part of 12 or more of the last 14 tax years.
  • Since 6 April 2017, non-doms who have been UK tax resident in at least 15 of the last 20 UK tax years will be treated as domiciled (“deemed domiciled”) in the UK. They will then no longer be able to claim the remittance basis and must declare worldwide income and gains on an arising basis.


Non-doms can decide annually whether to claim the remittance basis, which is helpful given the charges as above.  A remittance basis claim is not economic in all cases, particularly where the remittance basis charge applies.

It may be possible to structure investments so that income or gains are protected from UK without claiming the remittance basis.  This is particularly relevant for those who are liable to the remittance basis charge, or approaching “deemed domicile” status.

It may also be necessary to remit income and gains from offshore into the UK, often to buy a UK property or to fund other spending in the UK.  Careful planning is needed here to ensure that a remittance of funds to the UK is as tax-efficient as possible.

Non-domicile status can also have inheritance tax advantages, as a non-dom is only liable to inheritance tax on UK assets.   UK domiciled or deemed domiciled individuals are instead liable to inheritance tax on worldwide assets.

Inheritance tax planning can therefore be important, particularly as a non-dom approaches being deemed domiciled in the UK.  It is possible for a non-dom to ‘lock-in’ inheritance protection by setting up an ‘excluded property trust’.  A trust may also offer wider income tax and capital gains tax protection, and trust planning is a valuable option for many non-doms.
