Do I pay UK tax if I move to Monaco?

Answered by Jordan Onraet-Wells, Founder & Chartered Tax Adviser (CTA). Published 9 August 2026. Last reviewed 9 August 2026.

The short answer

Not on your worldwide income, provided you genuinely become non-resident under the Statutory Residence Test. Once you are UK non-resident, the UK taxes only UK-source income such as rental profits, certain pensions and gains on UK property, and Monaco itself charges residents no personal income tax, capital gains tax or wealth tax. The catch is that there is no comprehensive UK-Monaco double tax treaty, so if HMRC can show you are still UK resident you are taxed on worldwide income with no treaty tie-breaker to save you.

Monaco levies no personal income tax, capital gains tax, wealth tax or annual property tax on resident individuals; the only notable exception is French nationals, taxed by France under the 1963 France-Monaco convention.
There is no comprehensive UK-Monaco double tax treaty, only a Tax Information Exchange Agreement in force since 22 April 2015, so your protection rests entirely on being UK non-resident.
UK rental income stays UK-taxable under the Non-Resident Landlord Scheme, and selling UK residential property triggers non-resident CGT at 24% or 18%, reported and paid within 60 days.
UK inheritance tax is residence-based: if you were UK resident for 10 of the previous 20 tax years, your worldwide estate stays in scope for 3 to 10 years after you leave.
Return within roughly five years and the temporary non-residence rules can pull gains, and for returns on or after 6 April 2026 close-company dividends, back into UK tax.

Non-residence is everything

A Monaco residence card does not make you UK non-resident. Your UK status is decided purely by the Statutory Residence Test, based on your UK days and ties, and it is entirely possible to be Monaco-resident and UK-resident at the same time. In most countries a treaty tie-breaker would then decide who taxes you; between the UK and Monaco there is no such treaty, so dual residence simply means the UK taxes your worldwide income with no relief for the fact that you live in Monte Carlo. Plan your UK days conservatively, keep contemporaneous travel records, and time the move to fit a split-year treatment case so the year you leave divides cleanly.

What the UK keeps taxing

Even as a clean non-resident, UK-source income stays in the UK net. Rental profits fall within the Non-Resident Landlord Scheme, with 20% withholding unless HMRC approves gross payment, and a later sale of UK residential property triggers non-resident CGT at 24% or 18% with a 60-day reporting and payment deadline. Pensions need particular care: Monaco has no established local QROPS, so an offshore transfer while Monaco-resident will usually engage the 25% overseas transfer charge, and leaving the pension in the UK is often cleaner. Inheritance tax is now residence-based too, so a long-term UK resident keeps a worldwide IHT exposure for a tail of 3 to 10 years after leaving.

The five-year trap

The rule most likely to undo a Monaco move is temporary non-residence. If you were UK resident in at least four of the seven tax years before leaving and return within roughly five years, certain gains realised while away, and for returns on or after 6 April 2026 close-company distributions and dividends, can be taxed in the year you come back. Banking a tax-free gain during a short stint in Monaco rarely works; the move needs to be a genuine, long-term relocation.
