Moving to Monaco from the UK: The 2026 Tax Guide

Not if you are genuinely UK non-resident. Once you have left the UK and become non-resident under the Statutory Residence Test, the UK generally stops taxing your foreign income and gains. You remain taxable in the UK only on UK-source income, principally UK rental profits, certain UK pensions, and gains on UK land and property.

The danger is that Monaco residence and UK non-residence are two separate things. Renting or buying a flat in Monte Carlo and getting a Monaco residence card does not, by itself, make you UK non-resident. UK residence is decided purely by the SRT, based on your days in the UK and your connections here. If you spend too many days in the UK, or keep too many ties, you can be Monaco-resident and UK-resident at the same time.

In most double-taxation situations, a treaty tie-breaker would decide which country wins. Between the UK and Monaco there is no such treaty. That means being dual-resident is a genuine risk, and if it happens the UK simply taxes your worldwide income and gains with no relief for the fact that you live in Monaco. Getting the SRT right is therefore the single most important step in the whole move.

Monaco is one of the very few places that levies no personal income tax on its residents, a position in place since 1869. For an individual resident who is not a French national, the headline personal taxes are simply not charged.

• Personal income tax: none on residents (salaries, dividends, interest, pensions and business profits).
• Capital gains tax: none on gains from securities or real estate for individuals.
• Wealth tax: none.
• Annual property tax and residence or council tax: none for individuals.
• Inheritance and gift tax: charged only on assets situated in Monaco, and at 0% between spouses and in the direct line (parent to child). Rates rise for more distant relationships, reaching 16% for unrelated beneficiaries.

The one notable exception is French nationals. Under the 1963 France-Monaco tax convention, French citizens who moved their residence to Monaco after 13 October 1957 are treated by France as if they still lived there and remain subject to French income tax on their worldwide income. A UK national relocating to Monaco is not caught by this, but anyone holding French nationality needs specialist French advice before assuming Monaco is tax-free for them.

Some indirect and transactional taxes still apply. Monaco charges VAT broadly in line with France (a standard rate of 20%), and buying property carries registration and notary costs. There is no annual holding tax on the property, but the acquisition costs on a purchase are meaningful and should be factored into any relocation budget. Treat the precise property transfer costs as figures to confirm with a Monaco notary for your specific purchase.

Monaco residence is available to those who can house and support themselves in the Principality. For a UK national, the practical route to the carte de sejour (residence permit) rests on three pillars: accommodation, financial means, and a clean background.

• Accommodation in Monaco: either ownership of a Monaco property, or a registered rental lease (typically for at least 12 months) in your own name. Being housed within the same household on a qualifying owner's or tenant's declaration is also possible.
• Financial means: proof that you can support yourself without needing local employment. The most common route is a substantial deposit with a Monaco bank, which then issues a reference letter for your application. There is no minimum fixed in Monaco law, but banks in practice commonly require deposits in the region of EUR 500,000 upwards, and some private banks set higher thresholds. Treat the exact figure as one to confirm with the specific bank.
• Good standing: a clean criminal record and, for non-EU nationals, the appropriate French long-stay visa arranged via the French authorities before applying in Monaco.

The first residence card is typically valid for one year and is renewed, with longer-validity cards available over time as you build a residence history. The end-to-end process, from opening a bank account and securing accommodation to card in hand, commonly runs a few months. To keep the card, you must genuinely make Monaco your home, which dovetails neatly with the UK requirement that you also genuinely leave. From a UK perspective, real accommodation and real presence in Monaco are exactly the kind of evidence that supports a clean break.

The UK and Monaco do not have a comprehensive double taxation treaty. The only bilateral tax instrument between them is a Tax Information Exchange Agreement, signed in late 2014 and in force from 22 April 2015, which allows the two governments to share information but does nothing to allocate taxing rights or prevent double taxation.

This absence has two consequences. First, there is no residence tie-breaker. If the SRT makes you UK resident while you are also Monaco resident, there is no treaty article to hand the deciding vote to Monaco. The UK will simply tax your worldwide income and gains. Second, there is no treaty relief on UK-source income. UK rental income and UK pensions, for example, are taxed under domestic UK rules with no treaty reduction, so a move to Monaco does not soften the UK tax on income that stays UK-sourced.

The upshot is that, unlike a move to a treaty country such as Italy, Switzerland or Cyprus, there is no safety net if your non-residence is challenged. Everything depends on being cleanly and demonstrably UK non-resident under the SRT, and on keeping the evidence to prove it.

Your UK residence is determined solely by the Statutory Residence Test. It works through three stages: the automatic overseas tests (which, if met, make you non-resident), the automatic UK tests (which, if met, make you resident), and the sufficient ties test, which combines your UK days with connecting factors such as available accommodation, UK work, family, and prior residence.

For a UK leaver, the day counts are decisive. The permitted number of UK days before you become resident falls as you retain more UK ties. Someone who has been UK resident recently and keeps all the relevant ties can become resident on as few as 16 days in the UK, while someone with very few ties has far more headroom. Because there is no treaty backstop with Monaco, you should plan your UK days conservatively and keep contemporaneous records (travel dates, boarding passes, a day-count log) to evidence them.

The UK tax year runs 6 April to 5 April, and residence is normally an all-or-nothing status for the whole year. Split-year treatment can override this in the year you leave, taxing you as UK resident up to your departure and as non-resident afterwards, so your Monaco income after the split is outside UK tax. Split-year is not automatic: you must fall within one of the statutory cases, for example Case 1 (starting full-time work overseas) or Case 3 (ceasing to have a UK home). If you do not meet a case, you can be taxed as UK resident for the entire year of departure even though you left mid-year, so timing the move to fit a split-year case matters.

Keeping a UK home does not automatically make you UK resident, but it creates two ongoing UK tax exposures and can add an accommodation tie under the SRT. If you let the property, the rental profit remains UK-taxable and falls within the Non-Resident Landlord Scheme: tenants or letting agents may have to withhold tax at the basic rate of 20% unless HMRC approves you to receive rent gross, and you still report the income through Self Assessment even when no tax is due.

When you eventually sell UK residential property as a non-resident, Non-Resident Capital Gains Tax applies. Residential gains are taxed at 24% (higher rate) or 18% (within any basic-rate band), and the disposal must be reported and the tax paid within 60 days of completion through HMRC's UK Property Account, even where no tax is due. Private Residence Relief may reduce or remove the gain for periods the property was genuinely your main home, but it will rarely cover the whole gain once you have moved to Monaco.

UK pensions need their own thought. A move to Monaco does not free up your UK pension from UK rules, and transferring it to a Qualifying Recognised Overseas Pension Scheme (QROPS) can trigger the overseas transfer charge of 25% of the amount transferred unless a specific exclusion applies, typically that you are resident in the same country as the receiving scheme. Monaco has no established local QROPS and sits outside the EEA, and from 30 October 2024 the exclusion that had protected transfers to schemes in the EEA and Gibraltar was removed. In practice this means routing a UK pension through an offshore QROPS while Monaco-resident will usually engage the 25% charge, so leaving the pension in the UK and drawing it is often the cleaner route. Take specialist pensions advice before moving any pot.

The five-year temporary non-residence rule is the trap most likely to undo a Monaco move. If you were UK resident in at least four of the seven tax years before leaving, and your period of non-residence is around five years or less, certain income and gains realised while you are away can be pulled back into UK tax in the year you return. This typically captures gains on assets you owned before leaving, and, for returns on or after 6 April 2026, distributions and dividends from a UK close company received while abroad. In short, selling assets or extracting company profits tax-free in Monaco only works reliably if your non-residence is long-term. Treat Monaco as a genuine, multi-year relocation, not a short window to bank a gain.

Finally, do not overlook inheritance tax. IHT is now residence-based: if you were UK resident for at least 10 of the previous 20 tax years, your worldwide estate stays within the UK IHT net for a tail of between 3 and 10 years after you leave, the length rising with how long you were resident. Monaco charges IHT only on Monaco-situated assets, so for a period after your move your global estate can face UK IHT with no Monaco offset. Estate planning should be part of the move from day one.
