For high net worth families and family offices with international footprints, inheritance tax (or estate tax) remains one of the most significant threats to multi-generational wealth. Unlike income or capital gains taxes, these levies often strike at the point of death or lifetime gifts, sometimes with little warning and at rates that can exceed 40 to 55 percent. In 2026 the landscape is more complex than ever due to recent reforms in key jurisdictions, frozen thresholds in others, and increasing cross-border mobility.<\/p>\n
Understanding the rules by country is no longer optional. It is essential for effective estate planning, residency decisions, and the use of structuring tools such as trusts, insurance wrappers, and family holding companies. This guide summarises the key inheritance, estate, and gift tax rules in major jurisdictions for 2026, with a focus on planning opportunities and risks for internationally mobile families<\/a>.<\/p>\n Estate tax, such as the US federal version, is generally levied on the deceased\u2019s worldwide estate<\/a> before distribution. Inheritance tax, used in the UK, France, and Japan, is typically paid by the beneficiaries on the value they receive. Gift tax often applies to lifetime transfers, either as a separate tax or integrated with inheritance or estate tax, as in the US unified system.<\/p>\n Many countries also apply different rates and exemptions depending on the<\/a> relationship between the donor or deceased and the recipient (spouse, children, siblings, or unrelated persons). Double tax treaties for inheritance tax are limited compared with income tax treaties, making proactive structuring critical.<\/p>\n From 6 April 2025 the<\/a> UK replaced its long-standing domicile-based Inheritance Tax system with a residence-based regime. In 2026 individuals who are long-term residents, broadly UK resident for 10 out of the previous 20 tax<\/a> years, are subject to IHT on their worldwide assets. UK-situs assets remain taxable regardless of residency status.<\/p>\n The nil-rate band remains frozen at \u00a3325,000 per person until at least 2028, with an additional residence nil-rate band of \u00a3175,000 when passing a main residence to direct descendants. The combined allowance for a couple can reach \u00a31 million. Business Property Relief and Agricultural Property Relief are being restricted from April 2026, capping relief at \u00a31 million in many cases.<\/p>\n According to official guidance, long-term UK residents should review their position urgently, especially those who were previously non-domiciled. Planning options include lifetime gifting subject to the 7-year rule, use of trusts, and careful timing of residency changes. Exiting the UK can trigger a tail period of IHT exposure on non-UK assets in some cases. See the official rules here: UK Government guidance on long-term residents and IHT<\/a>.<\/p>\n France imposes inheritance tax at rates of up to 45 percent for direct descendants and as high as 60 percent for unrelated beneficiaries. Spouses and civil partners benefit from<\/a> a full exemption. Each child has a \u20ac100,000 allowance renewable every 15 years, while spouses enjoy an \u20ac80,724-plus allowance.<\/p>\n Life insurance policies written before age 70 can pass up to \u20ac152,500 per beneficiary tax-free outside the estate under certain conditions. The Imp\u00f4t sur la Fortune Immobili\u00e8re, France\u2019s real estate wealth<\/a> tax, continues alongside inheritance tax, creating a combined exposure that sophisticated families manage through holding structures and insurance.<\/p>\n France remains attractive for families who can utilise its generous spousal exemptions and life insurance planning, but non-residents with French property should be particularly careful.<\/p>\n Germany applies rates from 7 to 50 percent depending on the relationship class, with very high personal allowances of \u20ac500,000 for spouses and \u20ac400,000 per child. Business assets often qualify for 85 to 100 percent relief if the business is continued. This makes Germany relatively benign for close family transfers when properly structured<\/a>.<\/p>\n Italy taxes inheritances and gifts at 4 percent for spouses and direct descendants above a \u20ac1 million allowance per beneficiary, 6 percent for siblings, and 8 percent for others. The high allowances make Italy more favourable than headline rates suggest for immediate family<\/a>.<\/p>\n Spain operates a regional system. Many autonomous communities such as Madrid, Andalusia, and the Balearic Islands offer 99 to 100 percent relief or very high allowances for spouses, children, and parents, effectively eliminating inheritance tax for close family<\/a> in those regions. Other regions retain higher rates. Spain also maintains a Solidarity Tax on large fortunes in certain cases that interacts with regional wealth<\/a> taxes. Location of residence and assets matters enormously.<\/p>\n For deaths in 2026 the federal estate tax exemption is $15 million per individual or $30 million for a married couple. The top rate remains 40 percent. The unlimited marital deduction and<\/a> portability of unused exemption between spouses continue to provide significant planning opportunities.<\/p>\n However, US citizens and domiciliaries are taxed<\/a> on worldwide assets. Non-resident aliens are subject to estate tax only on US-situs assets above a low $60,000 threshold. Several states also impose their own estate or inheritance taxes with much lower exemptions, for example Massachusetts, Oregon, Illinois, and New York<\/a>.<\/p>\n According to the IRS the filing threshold for 2026 is $15 million. Families with US connections should consider life insurance, irrevocable trusts, and careful citizenship or residency planning. See the current thresholds here: IRS Estate Tax page<\/a>.<\/p>\n Several popular jurisdictions impose little or no inheritance or estate tax. These include the United Arab Emirates, Singapore, Australia, Canada, New Zealand, Portugal for direct line heirs, and Hong Kong. These locations are attractive for residency or holding structures, but families must consider substance requirements, other taxes such as income or wealth taxes, exit taxes, and Controlled Foreign Company or anti-avoidance rules in their home countries.<\/p>\n A clear global overview of rates and rules is available in this 2026 comparison: Inheritance Tax by Country: Global Rates Comparison 2026<\/a>.<\/p>\n The table below ranks major jurisdictions from Best in Class (most favourable) to Most Demanding for families with close family heirs (spouse and direct descendants). Classification considers effective tax burden after exemptions and reliefs, simplicity, anti-avoidance complexity, certainty, and suitability for internationally mobile families in 2026.<\/p>\n Classification Criteria<\/strong> Best in Class: 0 percent or near-zero effective tax for close family, simple rules, high certainty. Highly Favourable: Low effective rates or very high exemptions and reliefs. Favourable: Manageable rates with good reliefs available; planning adds clear value. Moderate: Higher rates or complexity but workable with proper structuring. Challenging: High headline rates, lower exemptions, or complex anti-avoidance. Most Demanding: Very high rates, broad worldwide scope, limited reliefs, or aggressive lookback rules.<\/p>\nKey Distinctions: Estate Tax versus Inheritance Tax versus Gift Tax<\/h2>\n
