Quick answer
Monaco has NO inheritance, estate, or gift tax for direct-line transfers, spouses, children, parents and grandparents pay 0%. Other rates: 8% siblings; 10% uncles, aunts, nieces and nephews; 13% other relatives; 16% non-relatives. Monaco’s regime applies to Monaco-situated assets only. For UK families: if you’re a UK long-term resident under the 2025 test, your worldwide assets including any Monaco property remain in UK IHT scope at 40%. The UK and Monaco have no specific IHT treaty (Monaco doesn’t tax direct heirs), but UK unilateral relief credits any Monaco IHT paid against UK IHT on the same asset. Monaco is famously tax-efficient for residents but the UK tax position for British nationals owning Monaco-situated property is largely unchanged by Monaco’s low rates. This guide explains Monaco’s IHT regime for UK families in 2026, the cross-border interaction with UK IHT, and the planning considerations.

As a UK family with assets or connections to Monaco, understanding the interaction between Monaco’s inheritance tax and UK inheritance tax (IHT) is crucial to protecting your estate. The UK’s shift from domicile-based to residence-based IHT from April 2025 has made it essential for UK nationals and expats to reconsider their estate planning strategies, and for those with Monaco connections, the stakes are especially high.
We are here to guide families through the complexities of cross-border wealth transfer, helping to ensure that your assets are protected efficiently and in compliance with both UK and Monegasque law.

Key Takeaways
- Monaco levies no inheritance tax on transfers between spouses and direct descendants, but the UK charges IHT at 40% on the worldwide estate of UK-domiciled individuals (and from April 2025, long-term UK residents) above the nil rate band of £325,000 (gov.uk, Inheritance Tax).
- The UK’s move to a residence-based IHT system from April 2025 significantly affects UK nationals living in Monaco, particularly those who have been UK-resident for 10 of the previous 20 tax years.
- Without coordinated cross-border planning, families risk double taxation or unexpected liabilities on both sides, and there is no comprehensive UK-Monaco double taxation treaty covering inheritance tax.
- Lifetime trusts established under English law can play a critical role in protecting assets for future generations, England invented trust law over 800 years ago, and it remains one of the most powerful asset protection tools available.
- Specialist guidance covering both jurisdictions is essential, the law, like medicine, is broad, and you need an expert who understands both systems.
Understanding Inheritance Tax in Monaco
Three rule changes you may need to consider (2026/27)
1. Pensions become subject to IHT from 6 April 2027. Most unused defined-contribution pension pots currently sit outside the estate for IHT, that ends on 6 April 2027 (gov.uk policy paper). HMRC estimates around 10,500 estates will face IHT for the first time as a result.
2. Business and agricultural property reliefs capped at £2.5m per person from 6 April 2026. Above the cap, only 50% relief applies, effective IHT of 20%. AIM shares dropped to 50% relief and do not use the £2.5m allowance (Saffery, APR/BPR reforms).
3. The NRB, RNRB and £2m taper threshold are frozen until 5 April 2031 following the 2024 and 2025 Budgets (gov.uk, NRB and RNRB freeze). With inflation, more estates will be pulled into IHT each year, a process commonly called “fiscal drag.”
For UK families with assets in Monaco, understanding the local inheritance tax landscape, and how it interacts with UK IHT, is crucial. We’re here to help you safeguard your legacy by providing clear guidance on both systems.
Monaco’s inheritance tax system is notably generous for close family members, but the real complexity arises from the UK side. As a UK family with assets in the Principality, it’s essential to grasp how both regimes apply to your situation. Monaco does not levy inheritance tax on transfers between spouses, children, or direct descendants. Its tax only applies to Monaco-situated assets, and even then, rates for close family are 0%. However, UK nationals remain subject to UK IHT on their worldwide estate, including Monaco assets, unless careful planning is undertaken. The nil rate band has been frozen at £325,000 per person since 2009, and it is confirmed frozen until at least April 2031. With property values rising steadily, this freeze means more and more families are being caught by IHT, including those with relatively modest UK homes alongside Monaco assets.
What is Inheritance Tax?
Inheritance tax (IHT) is a tax levied on the estate of a deceased person before assets pass to their heirs. In the UK, IHT is charged at 40% on the taxable estate above the nil rate band (NRB) of £325,000 per person. A reduced rate of 36% applies if 10% or more of the net estate is left to charity. There is also the residence nil rate band (RNRB) of £175,000 (gov.uk, RNRB) per person, available when a qualifying residential interest passes to direct descendants, children, grandchildren, or step-children. For a married couple, the combined maximum exemption is £1,000,000 (£650,000 NRB + £350,000 RNRB), as unused allowances transfer between spouses.
Monaco also has a form of inheritance tax, called droits de mutation par décès, but it only applies to assets situated within the Principality, and the rate depends on the relationship between the deceased and the beneficiary. Crucially, transfers between spouses and direct descendants in Monaco attract a 0% rate.
Understanding both systems is vital because a UK national with Monaco assets may face UK IHT on their worldwide estate and Monegasque duties on their Monaco-based assets. There is no comprehensive double taxation treaty between the UK and Monaco covering inheritance tax, which makes proactive planning essential. For more detailed information on Monaco’s tax regulations, you can visit Monaco Properties.
How is it Applied in Monaco?
In Monaco, inheritance tax is applied to assets such as real estate, bank accounts, and other financial assets located within the Principality. The tax rates depend entirely on the relationship between the deceased and the beneficiary:
- Spouses, children, and direct descendants: 0%, no tax payable
- Siblings: 8%
- Uncles, aunts, nephews, nieces: 10%
- Unrelated individuals: 16%
To illustrate, if a UK national owns a property in Monaco and leaves it to their children, no Monegasque inheritance tax is due. However, that same property would still form part of their worldwide estate for UK IHT purposes, potentially attracting a 40% charge above the nil rate band. If the property were instead left to a sibling or an unrelated friend, both Monegasque duties and UK IHT could apply, creating a punishing combined tax burden.
This is why it’s essential to understand both sets of regulations. The Monaco side may be straightforward for close family, but the UK exposure is where families are often caught out. We’re here to guide you through this process, providing specialist advice tailored to your specific cross-border situation.
Key Differences Between UK and Monaco Taxation
Understanding the differences between UK and Monaco inheritance taxation is crucial for effective estate planning. The two systems operate on fundamentally different principles, and getting this wrong can be extremely costly.
Rates of Inheritance Tax
The rates of inheritance tax in the UK and Monaco differ dramatically. In the UK, IHT is charged at a flat 40% on the taxable estate above the nil rate band (reduced to 36% if 10% or more of the net estate is left to charity). In Monaco, as noted above, direct descendants and spouses pay nothing, with rates for more distant relatives ranging from 8% to 16%.
The following table illustrates the key differences:
| Country | Inheritance Tax Rate | Nil Rate Band / Exemption |
|---|---|---|
| UK | 40% (36% with charitable legacies) | £325,000 per person (NRB) + up to £175,000 RNRB for direct descendants inheriting a residence. Combined maximum for married couple: £1,000,000 |
| Monaco | 0% (spouses/direct descendants) to 16% (unrelated) | No threshold, rate depends entirely on the relationship to the deceased |
Exemptions and Reliefs
Exemptions and reliefs also differ significantly between the two jurisdictions. In the UK, key reliefs include the nil rate band (£325,000, frozen since 2009 and confirmed frozen until at least April 2031), the residence nil rate band (£175,000, available only when a qualifying residence passes to direct descendants, it is not available for nephews, nieces, siblings, friends, or charities), the spouse exemption (unlimited transfers between spouses and civil partners), and reliefs for business and agricultural property. It’s worth noting that the RNRB tapers by £1 for every £2 the estate exceeds £2,000,000 in value, something that can easily catch families with Monaco property. Monaco, on the other hand, takes a simpler approach, the exemption is based on relationship rather than value thresholds.
Key exemptions in Monaco include:
- Complete exemption from inheritance tax for direct descendants and spouses (0% rate)
- Reduced rates for siblings (8%), nephews, nieces, uncles, and aunts (10%)
- Higher rates (up to 16%) for more distant relatives and unrelated individuals
The critical point for UK families is this: even if your Monaco assets attract 0% Monegasque tax, you may still owe 40% UK IHT on those same assets if you are UK-domiciled or, from April 2025, have been a long-term UK resident (resident for at least 10 of the previous 20 tax years). There is no automatic credit between the two systems in the way there would be with countries that have a double taxation treaty with the UK. Understanding this interaction is vital for protecting your estate from an unnecessary and potentially devastating tax charge.
Legal Framework Surrounding Inheritance in Monaco
Understanding the legal framework surrounding inheritance in Monaco is crucial for effective estate planning. Monaco’s Civil Code governs succession, and it contains rules that are fundamentally different from English law, particularly the concept of forced heirship, which does not exist in England and Wales.
Who Benefits from Inheritance?
In Monaco, the law dictates how inheritance is distributed among heirs through the concept of the reserved portion (réserve héréditaire). This ensures that certain heirs, primarily children, receive a expected minimum share of the estate, regardless of what the will says. This is a critical difference from English law, where testamentary freedom allows you to leave your assets to whomever you choose (subject to potential claims under the Inheritance (Provision for Family and Dependants) Act 1975).
The reserved portion in Monaco varies depending on the number of children:
| Number of Children | Reserved Portion |
|---|---|
| 1 | 1/2 |
| 2 | 2/3 |
| 3 or more | 3/4 |
The remaining portion (the quotité disponible) is the only part of the estate that the deceased can freely distribute by will. For UK families accustomed to full testamentary freedom, this can come as a significant and unwelcome surprise. Whether Monaco’s forced heirship rules apply to your situation will depend on factors including your nationality, domicile, and the type and location of assets involved. This is an area where specialist cross-border advice is essential.
Formalities Required for Inheritance
Monaco has specific formalities that must be observed when dealing with inheritance. One of the key requirements is the notarised will (testament authentique), which must be drafted and signed before a Monegasque notary. While English-law wills may be recognised in Monaco under certain circumstances, having a will that specifically covers your Monaco assets, drafted in compliance with local requirements, is strongly advisable.
Additionally, the succession process in Monaco involves a formal declaration of the deceased’s assets and liabilities, which must be filed with the Monegasque authorities within a specified timeframe. Failure to comply with these formalities can lead to complications, delays, and potential disputes among heirs.
By understanding and working within Monaco’s legal framework, while simultaneously ensuring your UK estate planning is robust, you can ensure that your estate is distributed according to your wishes, while minimising potential conflicts and tax liabilities across both jurisdictions.
Implications for UK Families
For UK families with assets in Monaco, navigating the interaction between two different tax systems is essential to protecting their estate. The real danger is not Monaco’s tax, which is generous for close family, but rather the UK’s worldwide IHT charge, which can catch families off guard.
How UK Nationals are Affected
UK nationals with assets in Monaco face a dual challenge. On the Monaco side, transfers to spouses and direct descendants are outside the scope of IHT. But on the UK side, HMRC treats your worldwide estate, including Monaco property, bank accounts, and investments, as subject to IHT at 40% above the nil rate band. This means a Monaco apartment worth £2 million could generate a UK IHT bill of hundreds of thousands of pounds, even if Monaco charges nothing.
Key Considerations:
- UK-domiciled individuals are subject to IHT on their worldwide assets, including those in Monaco, regardless of where they reside.
- From April 2025, the UK has moved to a residence-based IHT system: individuals who have been UK-resident for at least 10 of the previous 20 tax years will be within scope of UK IHT on worldwide assets, even if they have acquired a domicile of choice elsewhere. There is also a “tail”, after leaving the UK, you remain within scope for a period depending on how long you were resident.
- There is no comprehensive UK-Monaco double taxation treaty covering inheritance tax, so relief from double taxation is not automatic and must be carefully planned. Unilateral relief may be available in some circumstances, but this should never be assumed.
- Monaco’s forced heirship rules (réserve héréditaire) may conflict with English testamentary freedom, creating complications if your will is not properly structured for both jurisdictions.
Planning Strategies for Inheritance
Effective planning is crucial to minimise the combined impact of both jurisdictions’ tax rules. We recommend exploring various strategies to safeguard your estate. As Mike Pugh often says: plan, don’t panic.
| Strategy | Description | Benefit |
|---|---|---|
| Lifetime Trusts under English Law | Establishing an irrevocable discretionary trust can remove assets from your taxable estate. Transfers directly into a discretionary trust are chargeable lifetime transfers (CLTs), not potentially exempt transfers, but if the value transferred is within the available nil rate band, there is no entry charge. The assets are then managed under the relevant property regime, with a maximum periodic charge of 6% (and for most family estates, this can be nil). | Protects assets from the 40% IHT charge, provides control over distribution through the trustees, and can protect against divorce, local authority care fee claims, and family disputes. Trust assets also bypass probate delays entirely, trustees can act immediately on the settlor’s death |
| Separate Wills for Each Jurisdiction | Having a Monaco-specific will for Monaco assets and a separate English will for UK assets avoids the risk of one will inadvertently revoking the other. | Ensures compliance with both legal systems and avoids probate delays in either jurisdiction |
| Lifetime Gifting | Making gifts during your lifetime can reduce the taxable estate. Gifts to individuals become potentially exempt transfers (PETs) and fall outside the estate entirely if you survive 7 years. Note that taper relief (HMRC IHTM14612), which reduces the tax rate on PETs where the donor dies between 3 and 7 years, only applies when gifts exceed the nil rate band of £325,000. | Reduces IHT liability, but beware the gift with reservation of benefit (GROB) rules if you continue to benefit from the asset. If HMRC treats a gift as a GROB, it remains in your estate regardless of how long you survive |
| Life Insurance Written in Trust | A life insurance policy placed into trust provides an immediate cash sum on death to cover any IHT liability, without the payout itself being subject to IHT. Mike’s Life Insurance Trusts are typically free to set up. | Ensures heirs have funds to pay any tax bill without being forced to sell Monaco or UK property, IHT is due within six months of death, and cross-border probate can take far longer |
By understanding the implications of both Monaco’s and the UK’s inheritance laws and implementing effective planning strategies, UK families can protect their assets and ensure a smoother transition of wealth to future generations.
Protecting Your Estate from Inheritance Tax
Protecting your legacy from unnecessary tax liabilities requires a clear understanding of how UK IHT interacts with Monaco’s more favourable regime. Many UK families assume that because Monaco charges 0% on transfers to close family, they have no inheritance tax problem. This is a dangerous misconception, HMRC does not care what Monaco charges. If you are within scope of UK IHT, your worldwide estate is taxed at 40% above the nil rate band.
Importance of Financial Planning
Proactive financial planning is essential for UK families with Monaco assets. The starting point is understanding your exposure: a UK-domiciled individual with a £3 million estate (including a £2 million Monaco apartment) could face an IHT bill exceeding £1 million. With proper planning, this can be significantly reduced, or in some cases, substantially mitigated.
Key aspects to consider include:
- Assessing your total worldwide assets and understanding which are within scope of UK IHT
- Understanding your domicile and residence status, and how the April 2025 changes to UK IHT rules affect you. Under the new residence-based regime, individuals who have been UK-resident for at least 10 of the previous 20 tax years fall within scope of worldwide IHT, even if they have left the UK
- Identifying available UK reliefs and exemptions: the nil rate band (£325,000), the residence nil rate band (£175,000 for qualifying estates where the residence passes to direct descendants), the spouse exemption, and business/agricultural property relief, noting that from April 2026, BPR and APR will be capped at 100% for the first £1 million of combined business and agricultural property, with only 50% relief on the excess
- Considering whether lifetime trusts, gifting strategies, or restructuring the ownership of assets could reduce your IHT exposure, and doing so well in advance of any foreseeable need
Tools to Safeguard Your Legacy
Various tools and strategies can be employed to protect your estate across both jurisdictions. England invented trust law over 800 years ago, and trusts remain one of the most powerful tools for cross-border estate planning:
| Tool/Strategy | Description | Benefits |
|---|---|---|
| Irrevocable Discretionary Trust | Assets are transferred to trustees who hold them for the benefit of a class of beneficiaries. The settlor no longer owns the assets for IHT purposes. A trust is not a separate legal entity, it is a legal arrangement where the trustees hold legal ownership and manage assets according to the trust deed. Transfers into a discretionary trust are CLTs, and if the value is within the available NRB, there is no entry charge. The trust is then managed under the relevant property regime, with a maximum 10-year periodic charge of 6% on trust assets above the NRB, for most family estates, this can work out to be nil or very modest. | Removes assets from the taxable estate, protects against divorce and local authority care fee claims, bypasses probate delays entirely (trustees can act immediately on death), and provides flexibility through the trustees’ discretion |
| Life Insurance Written in Trust | A life insurance policy placed into trust provides an immediate payout on death that is not part of the estate. Mike’s Life Insurance Trusts are typically free to set up. | Provides immediate liquidity to pay IHT bills, preventing the forced sale of Monaco or UK property. IHT is due within six months of death, having cash available avoids the need to sell assets at a disadvantageous time |
| Lifetime Gifting with the 7-Year Rule | Gifts to individuals are potentially exempt transfers (PETs). If you survive 7 years, the gift falls entirely outside your estate. If the donor dies between 3 and 7 years, taper relief reduces the rate of tax, but only on gifts exceeding the NRB of £325,000. There is also an annual gift exemption of £3,000 per tax year (with one year of carry-forward), plus small gift exemptions of £250 per recipient. | Reduces the taxable estate, but you must genuinely give up the asset. If you continue to benefit from it (e.g. gifting a property but continuing to live in it rent-free), the gift with reservation of benefit rules mean the asset remains in your estate for IHT purposes, regardless of how long you survive |
| Specialist Cross-Border Estate Planning | Coordinating your UK and Monaco estate plans to ensure they work together, not against each other. This includes separate jurisdiction-specific wills, appropriate trust structures, and careful consideration of Monaco’s forced heirship rules alongside English testamentary freedom. | Avoids one will revoking another, ensures compliance with forced heirship rules, and minimises the risk of double taxation |

Potential Consequences of Not Planning
Understanding the potential consequences of not planning for inheritance tax is crucial for UK families with assets in Monaco. The combination of UK IHT at 40% and potential Monegasque duties (for non-direct heirs) can dramatically reduce the value of an inheritance if left unmanaged.
Tax Liabilities for Heirs
When a UK national passes away with assets in Monaco, their heirs may face substantial tax liabilities from the UK side, even if Monaco charges nothing. HMRC will assess the deceased’s worldwide estate, including the full value of any Monaco property, bank accounts, and investments. On a Monaco apartment worth £2 million, the UK IHT liability alone (after the nil rate band) could exceed £670,000.
For heirs who are not spouses or direct descendants, the situation is worse. They face not only UK IHT at 40% but also Monaco’s droits de mutation at rates of up to 16%. Without proper planning, the combined tax burden could approach 50% of the asset’s value. During probate, which for cross-border estates can take 12-24 months or longer, assets may be frozen in both jurisdictions, leaving heirs unable to access funds to pay the very tax bills being demanded. In England and Wales, IHT must normally be paid within six months of death, but a Grant of Probate for a complex cross-border estate can take far longer to obtain, creating acute cash flow pressure. Assets held in trust, by contrast, bypass probate entirely, trustees can act immediately on death without waiting for any court-issued grant.
Loss of Family Assets
The loss of family assets is a very real concern for UK families who fail to plan. Without a well-structured plan, families risk being forced to sell Monaco property, often at a disadvantageous time, to pay IHT bills. In England and Wales, IHT is due within six months of the death, but obtaining a Grant of Probate for a cross-border estate often takes far longer, creating acute cash flow pressure. The reality is stark: without planning, HMRC must be paid before your family can fully access their inheritance.
Consider the following comparison:
| Scenario | Estate Value | UK IHT Liability (40% above NRB) | Monaco Duty (to children at 0%) | Total Tax | Net to Heirs |
|---|---|---|---|---|---|
| No Planning (UK-domiciled, assets in own name) | £2,000,000 | £670,000 | £0 | £670,000 | £1,330,000 |
| With Trust Planning (assets held in a properly structured irrevocable discretionary trust) | £2,000,000 | Significantly reduced, potentially managed through the relevant property regime at a maximum periodic charge of 6%, which for many estates is nil or minimal | £0 | Minimal | Up to £2,000,000 |
We’re here to help you safeguard your legacy. By understanding the potential consequences of not planning and taking proactive steps now, you can protect your family’s assets and ensure their smooth transfer to future generations. Trusts are not just for the rich, they’re for the smart.
The Role of Specialist Advisors for UK Families with Monaco Assets
The intricate world of cross-border inheritance tax demands the expertise of specialists who understand both UK and Monegasque law. For UK families with assets in Monaco, working with the right advisors is not a luxury, it’s a necessity.
Why You Need Expert Guidance
Monaco’s inheritance rules are straightforward for close family, but the interaction with UK IHT law is anything but simple. The law, like medicine, is broad. You wouldn’t want your GP doing surgery. Similarly, you need advisors who specialise in cross-border estate planning, not generalists who deal with it occasionally.
Expert estate planning specialists can help with:
- Understanding your IHT exposure on worldwide assets, including Monaco property and investments
- Developing effective strategies that work within both UK and Monegasque legal frameworks
- Structuring lifetime trusts under English law to protect Monaco and UK assets, irrevocable discretionary trusts with standard and overriding powers give trustees defined flexibility without compromising the IHT position
- Coordinating separate wills for each jurisdiction to avoid one inadvertently revoking the other
- Ensuring compliance with Monaco’s forced heirship rules while preserving your wishes as far as possible
- Registering any trusts on the Trust Registration Service (TRS) within 90 days of creation, as required for all UK express trusts
Finding a Reliable Advisor
Finding a reliable advisor with genuine expertise in both UK IHT and Monaco succession law is essential. Here are the key criteria to consider:
| Criteria | Description | Importance |
|---|---|---|
| Cross-Border Expertise | Look for advisors who specifically handle UK-Monaco estate planning, not just domestic UK or Monaco-only matters | High |
| Trust Law Knowledge | Ensure the advisor understands English trust law and can establish appropriate lifetime trust structures, discretionary trusts, interest in possession trusts, or settlor-excluded trusts as appropriate. A trust is a legal arrangement, not a separate legal entity, the trustees hold legal ownership, and the trust deed governs how they manage and distribute the assets | High |
| Transparent Pricing | Look for advisors who publish their prices openly. MP Estate Planning is the first and only company in the UK that actively publishes all prices on YouTube. Straightforward trusts typically start from £850 | High |
| Reputation and Track Record | Check for client testimonials, reviews, and evidence of successful cross-border planning outcomes | Medium |
By choosing the right specialist, you can ensure that your estate is managed effectively across both jurisdictions, and your loved ones are protected from an unnecessary tax burden that could have been avoided with proper planning.
Creating an Estate Plan for UK Families with Monaco Assets
For UK families with assets in Monaco, crafting an effective estate plan that addresses both jurisdictions is essential for protecting your wealth. We’re here to help you safeguard your legacy.
Creating a cross-border estate plan involves several key elements that must be carefully coordinated to ensure that your wishes are respected, your family’s future is protected, and your tax exposure is minimised across both the UK and Monaco.
Key Elements of an Effective Plan
An effective estate plan for UK families with Monaco assets should include:
- A clear understanding of your domicile and residence status, and how the UK’s shift to residence-based IHT from April 2025 affects your worldwide tax exposure. Under the new rules, if you have been UK-resident for at least 10 of the previous 20 tax years, your worldwide assets fall within scope of UK IHT.
- A comprehensive inventory of your worldwide assets, including Monaco property, UK property, pensions (including SIPPs, which from April 2027 will be subject to IHT on death), investments, and other valuable possessions, with an understanding of which are within scope of UK IHT and which may also attract Monegasque duties.
- Separate wills for each jurisdiction: a Monaco will covering Monaco-situated assets (complying with local notarial requirements) and an English will covering UK and other assets. These must be carefully drafted to avoid one revoking the other, a common and devastating mistake.
- Consideration of lifetime trusts under English law as a vehicle for protecting assets from IHT. Irrevocable discretionary trusts can remove assets from your taxable estate, bypass probate delays (trustees can act immediately on death without waiting for a Grant of Probate), and protect against divorce, creditor claims, and local authority care fee assessments. No beneficiary has an automatic right to the trust assets, the trustees exercise discretion based on the trust deed and the settlor’s letter of wishes.
- A Lasting Power of Attorney (LPA) for property and financial affairs, and a health and welfare LPA, ensuring someone you trust can act on your behalf if you lose capacity. Without an LPA, your family would need to apply to the Court of Protection for a deputyship order, a process that is slower, more expensive, and involves ongoing court supervision.
- A letter of wishes to guide your trustees on how you would like them to exercise their discretion, while keeping the flexibility that makes discretionary trusts so powerful. This is not a legally binding document, but it provides invaluable guidance to trustees.
Common Pitfalls to Avoid
When creating an estate plan covering Monaco assets, there are several common pitfalls that catch UK families out:
- Having only one will for both jurisdictions. An English will that revokes “all previous wills” could inadvertently revoke a Monaco will, and vice versa. Always have jurisdiction-specific wills drafted by specialists in each system.
- Ignoring Monaco’s forced heirship rules. Unlike English law, where you have full testamentary freedom, Monaco requires that a reserved portion of your estate passes to your children. Failing to account for this can result in your will being partially overridden by Monegasque courts.
- Assuming Monaco’s 0% rate means no tax is due. Monaco’s 0% rate applies to direct descendants and spouses, but UK IHT at 40% still applies to your worldwide estate if you are within scope. The Monaco rate is irrelevant to HMRC.
- Failing to plan early enough. Many IHT-efficient strategies, particularly lifetime trusts and the 7-year rule for gifting, require time to take full effect. Transfers into a discretionary trust are chargeable lifetime transfers, and if the settlor dies within 7 years, the transfer is reassessed at 40% (with taper relief and credit for any 20% lifetime charge already paid). Last-minute planning is far less effective.
- Not seeking specialist cross-border advice. A generalist solicitor or financial adviser may not understand the interaction between English trust law, UK IHT, and Monegasque succession rules. This is a specialist area requiring specialist knowledge. As Mike says: you wouldn’t want your GP doing surgery.
| Key Elements | Benefits |
|---|---|
| Separate jurisdiction-specific wills | Ensures compliance in both Monaco and the UK, avoids accidental revocation |
| Lifetime trust under English law | Removes assets from taxable estate, bypasses probate delays, protects against divorce and local authority care fee claims |
| Comprehensive asset inventory | Identifies worldwide IHT exposure and allows for targeted planning |
By understanding the key elements of an effective cross-border estate plan and avoiding these common pitfalls, you can safeguard your legacy and ensure that your family’s future is protected, no matter which side of the Channel they live on.
Frequently Asked Questions About Monaco’s Inheritance Tax
Monaco’s inheritance tax laws, and their interaction with UK IHT, can be complex. Here are the most common questions we receive from UK families with Monaco assets.
What Happens if I Die Without a Will?
Dying without a will when you hold assets in both the UK and Monaco creates a complicated cross-border nightmare for your family. In Monaco, your assets will be distributed according to Monegasque intestacy rules, which are based on civil law principles and include forced heirship provisions for children. In England and Wales, your UK assets will pass under the intestacy rules set out in UK legislation, which follow a strict hierarchy, spouse or civil partner first (with a statutory legacy and a share of the remainder if there are children), then children, then parents, and so on. Neither set of rules may reflect what you actually wanted, and your family could face delays of 12-24 months or more while both jurisdictions’ processes run in parallel. During this time, all sole-name assets in both countries are likely to be frozen. Having properly drafted, jurisdiction-specific wills is essential.
Are There Special Rules for Foreign Assets?
Yes. Monaco’s inheritance tax generally applies only to assets situated within the Principality. However, if you are within scope of UK IHT (because you are UK-domiciled or, from April 2025, a long-term UK resident), HMRC will assess your worldwide estate, including all Monaco assets. There is no comprehensive UK-Monaco double taxation treaty covering inheritance tax. This means careful planning is needed to avoid being taxed twice on the same assets. In some cases, unilateral relief may be available to credit foreign tax paid against the UK liability, but this depends on the specific circumstances and should not be assumed without specialist advice. For detailed guidance, you can consult specialist resources on Monaco inheritance tax.
| Asset Type | Monaco Inheritance Tax | UK IHT Implications |
|---|---|---|
| Real Estate in Monaco | Subject to Monaco duties (0% for spouses/direct descendants) | Included in worldwide estate for UK IHT at 40% above NRB |
| UK Real Estate | Not subject to Monaco duties | Subject to UK IHT. May qualify for RNRB (£175,000) if passed to direct descendants, but not available for nephews, nieces, siblings, friends, or charities |
| Bank Accounts and Investments in Monaco | Subject to Monaco duties based on beneficiary relationship | Included in worldwide estate for UK IHT |
By understanding these rules and planning accordingly, ideally with specialist advice covering both jurisdictions, you can protect your estate and ensure that your heirs are not faced with unexpected tax liabilities from either side.
Taking Action: Next Steps for UK Families
Protecting your estate and legacy across borders requires careful planning and specialist guidance. As a UK family with assets in Monaco, taking action now, rather than waiting until it’s too late, is the single most important step you can take.
Getting Started with Estate Planning
Begin by assessing your total worldwide estate: UK property, Monaco property, pensions (including SIPPs, which from April 2027 will be subject to IHT on death), investments, bank accounts, and any other assets. Understand your domicile and residence status, and consider how the UK’s residence-based IHT regime from April 2025 affects your position. If you have been UK-resident for at least 10 of the previous 20 tax years, your worldwide assets are within scope of UK IHT, even if you now live in Monaco. Our team of specialists can help you create a tailored plan that addresses both UK and Monaco requirements, using tools such as irrevocable discretionary trusts, life insurance trusts, and coordinated cross-border wills.

FAQ
What is Monaco’s inheritance tax policy?
Monaco levies inheritance tax (droits de mutation par décès) only on assets situated within the Principality, and the rate depends on the beneficiary’s relationship to the deceased. Spouses and direct descendants (children, grandchildren) pay 0%. Siblings pay 8%, other relatives 10%, and unrelated individuals 16%. However, if you are within scope of UK inheritance tax, because you are UK-domiciled or a long-term UK resident under the new residence-based rules from April 2025, HMRC will also assess your Monaco assets as part of your worldwide estate at 40% above the nil rate band of £325,000.
How does Monaco’s inheritance tax compare to the UK’s?
Monaco’s system is far more favourable for close family, spouses and children pay nothing. The UK charges a flat 40% on the taxable estate above the nil rate band (£325,000 per person, frozen since 2009 and confirmed frozen until at least April 2031). A reduced rate of 36% applies if 10% or more of the net estate is left to charity. The critical issue for UK families is that both systems may apply simultaneously: Monaco taxes Monaco-situated assets based on relationship, while the UK taxes your worldwide estate based on domicile or long-term residence. There is no comprehensive double taxation treaty between the UK and Monaco covering inheritance tax.
What happens if I die without a will in Monaco?
Dying without a will creates a cross-border mess. In Monaco, your assets will be distributed under Monegasque intestacy rules (based on civil law, with forced heirship provisions for children). In the UK, your assets pass under English intestacy rules, which follow a strict hierarchy and may not reflect your wishes at all. Neither set of rules may represent what you wanted, and the administration of a cross-border estate without wills can take years, during which assets in both jurisdictions may be frozen. We strongly recommend having separate, jurisdiction-specific wills for Monaco and UK assets.
Are foreign assets subject to inheritance tax in Monaco?
Generally, Monaco only taxes assets situated within the Principality. However, if you hold assets outside Monaco, those assets may be subject to the inheritance tax rules of the country where they are located. For UK nationals within scope of UK IHT, all worldwide assets, including those in Monaco, are subject to UK IHT at 40% above the nil rate band. There is no comprehensive UK-Monaco double taxation treaty covering inheritance tax, so unilateral relief may need to be claimed, and this should not be assumed without specialist advice.
How can I minimise inheritance tax liabilities for my heirs?
Effective cross-border estate planning is key. Strategies include establishing irrevocable discretionary trusts under English law to remove assets from your taxable estate (transfers into trust are chargeable lifetime transfers, and if within the available nil rate band, no entry charge applies), making lifetime gifts to individuals (which become potentially exempt transfers and fall outside the estate if you survive 7 years), placing life insurance policies into trust so the payout avoids IHT (these are typically free to set up), and having properly coordinated wills for each jurisdiction. The earlier you start, the more effective these strategies are, plan, don’t panic.
What role do specialist advisors play in Monaco’s inheritance tax landscape?
Specialist estate planning advisors with cross-border expertise are essential for UK families with Monaco assets. They can assess your worldwide IHT exposure, structure trusts and wills appropriately for both jurisdictions, navigate Monaco’s forced heirship rules, and ensure your planning is compliant with both UK and Monegasque law. The interaction between the two systems is complex, and generalist advice is rarely sufficient. As we often say: the law, like medicine, is broad, you need a specialist who understands both systems.
How do I get started with cross-border estate planning?
Start by getting a clear picture of your worldwide assets and understanding your domicile and residence status for UK IHT purposes, particularly how the April 2025 move to residence-based IHT affects you. Then consult with a specialist who understands both English trust law and Monegasque succession rules. You can fill out our contact form, call us at 0117 440 1555, or book a call with our team to begin the process.
What are the key elements of an effective cross-border estate plan?
An effective plan should include: separate jurisdiction-specific wills (one for Monaco assets, one for UK assets, drafted to avoid one revoking the other), consideration of lifetime trusts under English law to reduce IHT exposure (irrevocable discretionary trusts are the most commonly used and most protective), Lasting Powers of Attorney for property and financial affairs and for health and welfare, a letter of wishes for your trustees, and a full assessment of your worldwide estate to identify IHT exposure. Planning for Monaco’s forced heirship rules is also essential, you cannot simply override them with an English will.
Can I transfer my UK estate plan to Monaco?
Not directly. English and Monegasque law operate on fundamentally different principles, England allows full testamentary freedom while Monaco has forced heirship rules that expected your children a minimum share of the estate. An English will may not be fully recognised or enforceable in Monaco, and vice versa. The recommended approach is to have separate, coordinated estate plans for each jurisdiction, drafted by specialists who understand both systems. English trusts, however, are recognised as powerful planning tools that can work alongside Monegasque succession rules when properly structured.
How can I ensure my estate is distributed according to my wishes in Monaco?
Have a valid Monegasque will for your Monaco assets, drafted with a local notary. Be aware that Monaco’s forced heirship rules (réserve héréditaire) expected your children a minimum share, you cannot disinherit them as you could under English law. For your UK assets, an English will and potentially a lifetime trust can ensure your wishes are respected. A discretionary trust is particularly powerful because the trustees hold the assets and exercise discretion according to the
Forced Heirship, Testamentary Freedom and Governing Law: What UK Nationals Must Understand
One of the most significant, and frequently overlooked, legal tensions for UK nationals owning property in Monaco concerns the fundamental difference between how the two jurisdictions approach inheritance itself. English law grants broad testamentary freedom: you may, with limited exceptions, leave your estate to whomever you choose. Monegasque civil law, by contrast, incorporates the concept of réserve héréditaire (forced heirship), which reserves a protected share of the estate for certain close relatives, regardless of what a will may say.
How Forced Heirship Works in Monaco
Under Monegasque succession law, children, and in some circumstances other direct-line relatives, hold a statutory entitlement to a minimum portion of the deceased’s estate situated in Monaco. This réserve cannot generally be defeated by a will, a lifetime gift, or a contractual arrangement made under English law. In practice, this means a UK national who has carefully structured their English will to benefit a surviving partner or a discretionary trust may find that Monegasque-situated assets are subject to claims from children that override those intentions. The proportion of the estate subject to the réserve typically increases with the number of qualifying heirs. Our team would always recommend taking advice from a Monegasque notaire before finalising any cross-border estate plan involving immovable property in Monaco.
The Brussels IV Question Post-Brexit
The EU Succession Regulation, commonly referred to as Brussels IV (EU Regulation No 650/2012), allows an EU-resident individual to elect for the law of their nationality to govern their entire estate. This was potentially useful for UK nationals resident in Monaco-adjacent jurisdictions, as it could allow English law to apply and thereby sidestep forced heirship rules in participating EU member states. However, two critical points now apply. First, Monaco is not an EU member state and has never been within the scope of Brussels IV. Second, following the UK’s departure from the European Union, UK nationals can no longer invoke Brussels IV to assert English governing law even in EU member states where it previously applied. The HMRC Inheritance Tax guidance does not address foreign succession law conflicts directly, and the Inheritance and Trustees’ Powers Act 2013 governs English testamentary capacity and interpretation but has no extra-territorial effect on Monegasque situs rules. For UK nationals, the practical consequence post-Brexit is that any governing-law election must now be made expressly, and separately, in a Monegasque will drawn up before a local notaire, since English law choices are not automatically recognised in Monaco.
Governing-Law Elections and Practical Steps
In our experience, UK families holding Monegasque assets typically benefit from maintaining two coordinated wills: one governed by English law dealing with UK-sited assets, and a separate Monegasque will, drafted in French and executed before a Monegasque notaire, dealing specifically with Monaco-sited property. These documents must be carefully cross-referenced to avoid unintended revocation. The Monegasque will may include a governing-law recital, though the extent to which this can override the réserve héréditaire in respect of qualifying heirs remains a matter of local legal interpretation rather than certainty. We would generally recommend that UK executors obtain a written legal opinion from a Monaco-qualified practitioner before distributing any Monegasque asset, given the potential for competing claims under forced heirship rules.
Common Questions About Monaco Inheritance Tax
What is the inheritance tax in Monaco?
Monaco does levy inheritance tax, known locally as droits de succession, but the rates vary significantly depending on the relationship between the deceased and the beneficiary. Direct-line heirs, including children and parents, pay a rate of 0%, meaning those assets pass outside the scope of Monegasque inheritance tax entirely. Siblings are typically taxed at 8%, and more distant relatives at progressively higher rates. Unrelated beneficiaries may face rates of up to 16%. This structure makes Monaco markedly more favourable than many jurisdictions for family succession, though the réserve héréditaire rules discussed above mean that tax efficiency alone does not guarantee an estate passes as intended.
Do Monaco residents pay inheritance tax?
Monaco residents are generally subject to Monegasque droits de succession on assets situated in Monaco, applying the rates described above. However, residency status alone does not determine the full picture: the nationality of the deceased, the location of assets, and the existence of any applicable bilateral treaty may all affect liability. French nationals resident in Monaco are a notable exception, they remain subject to French succession rules by virtue of the Convention franco-monégasque du 18 mai 1963 (the 1963 France, Monaco fiscal convention), which preserves French taxing rights over French citizens regardless of Monaco residence. UK nationals do not benefit from an equivalent bilateral treaty with Monaco, meaning their Monegasque-sited assets are generally governed by Monegasque succession law and tax rules directly.
Quels sont les frais de succession à Monaco ?
Les droits de succession à Monaco sont calculés en fonction du lien de parenté entre le défunt et le bénéficiaire. Les héritiers en ligne directe, enfants et parents, bénéficient d’un taux de 0 %. Les frères et sœurs sont généralement imposés à 8 %, tandis que les personnes sans lien de parenté peuvent être soumises à un taux pouvant atteindre 16 %. À titre de comparaison, le taux standard britannique d’impôt sur les successions est de 40 % au-delà d’un seuil de 325 000 £ (exercice fiscal 2024/25). Ces différences de taux sont considérables et expliquent en partie pourquoi certaines familles britanniques fortunées détiennent des actifs à Monaco. Toutefois, la planification successorale internationale reste complexe et nécessite l’intervention de professionnels qualifiés dans les deux juridictions.
Quels sont les accords entre la France et Monaco ?
Le principal accord fiscal entre la France et Monaco en matière de succession est la Convention du 18 mai 1963 relative aux droits de succession. Cette convention prévoit que les ressortissants français résidant à Monaco restent soumis aux droits de succession français sur l’ensemble de leurs biens, où qu’ils soient situés. Elle vise à éviter que des résidents monégasques de nationalité française puissent contourner la fiscalité successorale française. Pour les familles britanniques, cet accord n’est pas directement applicable, mais il est utile d’en comprendre l’existence, car il illustre comment des accords bilatéraux peuvent modifier considérablement les obligations fiscales selon la nationalité du défunt. Il n’existe pas à ce jour d’accord équivalent entre le Royaume-Uni et Monaco, ce qui renforce l’importance d’une planification successorale spécifique pour les ressortissants britanniques détenant des actifs dans la Principauté.
