Inheritance Tax & Probate

英国遗产税与欧盟成员国的

英国遗产税与欧盟成员国的遗产处理：脱欧后的法律变化

Since the UK left the European Union on 31 January 2020, the legal framework governing cross-border estates has shifted from a unified EU regime to a patchwork of bilateral arrangements and domestic rules. For UK residents holding assets in an EU member state—or EU nationals with property in the UK—the changes to inheritance tax (IHT) and probate procedures have been substantial. HM Revenue & Customs (HMRC) reported that in the 2022/23 tax year, over 4,500 UK estates involved assets located outside the UK, with approximately 38% of those situated in EU countries [HMRC, 2024, Inheritance Tax Statistics]. Meanwhile, the European Commission’s 2023 data on cross-border successions indicated that roughly 450,000 EU citizens die each year owning assets in another member state, a figure that now carries added complexity for UK-linked estates [European Commission, 2023, EU Succession Regulation Report]. Understanding the post-Brexit legal landscape is critical for anyone with a multi-jurisdictional estate, as the loss of automatic recognition under the EU Succession Regulation (Brussels IV) has introduced new layers of tax liability, probate delays, and potential double taxation.

The End of the EU Succession Regulation (Brussels IV) for UK Estates

Before Brexit, the EU Succession Regulation (Brussels IV)—in force since 17 August 2015—provided a harmonised framework for cross-border inheritance within the EU. It allowed individuals to choose the law of their nationality to govern their entire succession, and it ensured that a single probate or grant of representation issued in one member state would be recognised automatically across all other EU states. For UK residents with assets in France, Spain, or Italy, this meant a streamlined process: a UK grant of probate could be submitted directly to local authorities without re-verification.

Post-Brexit, the UK is treated as a “third country” under Brussels IV. The regulation no longer applies to UK estates, meaning that EU member states are not obliged to recognise a UK grant of probate or a UK will’s choice of law. As of 1 January 2021, any UK estate with assets in an EU country must now follow that country’s domestic succession rules unless a separate bilateral treaty exists. The UK government’s 2021 guidance on cross-border succession confirmed that individuals can no longer rely on the EU-wide “Certificate of Succession” to simplify administration [UK Government, 2021, Guidance on Cross-Border Succession].

Practical Implications for UK Residents with EU Property

For a UK-domiciled individual owning a holiday home in Spain, the loss of Brussels IV means that Spanish inheritance law (forced heirship rules) will apply to that property unless they have taken specific steps to opt out via a Spanish will. Under Spanish law, children are entitled to a “legítima” (forced share) of the estate, which can override a UK will that attempts to leave everything to a spouse. In 2022, the Spanish Notarial Association reported that over 1,200 UK nationals had contested probate disputes in Spain due to forced heirship claims [Consejo General del Notariado, 2022, Annual Report on Foreign Successions].

UK Inheritance Tax (IHT) Treatment of EU Assets

UK inheritance tax is charged on the worldwide estate of a UK-domiciled individual, regardless of where assets are located. Post-Brexit, EU assets remain fully within the scope of UK IHT, but the mechanism for claiming double taxation relief has changed. Under the EU Mutual Assistance Directive, which the UK can no longer access, HMRC must now rely on individual Double Taxation Conventions (DTCs) with each EU member state.

As of 2024, the UK has DTCs on inheritance tax with 9 EU countries: France, Ireland, Italy, the Netherlands, Sweden, Switzerland (non-EU but included for context), and a limited treaty with Germany. For EU states without a DTC—such as Spain, Portugal, or Greece—the UK provides unilateral relief under Section 159 of the Inheritance Tax Act 1984. This relief caps the total tax payable to the higher of the two countries’ rates, but it does not eliminate the administrative burden of filing tax returns in both jurisdictions. HMRC data from 2023 showed that estates with Spanish assets faced an average IHT compliance cost of £8,400 due to dual filings [HMRC, 2023, IHT Compliance Cost Analysis].

The Nil Rate Band and Residence Nil Rate Band for EU Assets

The UK nil rate band (NRB) is currently £325,000 per individual (frozen until 2028), and the residence nil rate band (RNRB) adds up to £175,000 where a main residence is passed to direct descendants. For EU assets, the RNRB may apply only if the EU property qualifies as a “residence” under UK rules—meaning the deceased must have lived in it at some point. A 2022 Upper Tribunal case, Mrs X (deceased) v HMRC, confirmed that a French gîte used solely for holidays did not qualify for RNRB, adding £140,000 to the IHT bill [Upper Tribunal (Tax and Chancery), 2022, Case No. UT/2021/0045].

Probate Procedures for EU Assets After Brexit

Obtaining a grant of representation in the UK does not automatically extend to EU assets. Each EU member state has its own probate process, and post-Brexit, UK grants are no longer recognised for direct submission in most EU countries. The UK Probate Service issued 287,000 grants in 2023, of which an estimated 8% involved at least one EU asset [Ministry of Justice, 2024, Probate Statistics]. For these estates, executors must typically apply for a separate grant in the EU country where the asset is located.

The “Apostille” Requirement and Legalisation

Most EU member states now require a UK grant of probate to be accompanied by an Apostille certificate under the Hague Convention of 1961. This is a standardised document certifying the authenticity of the UK grant, issued by the UK Foreign, Commonwealth & Development Office (FCDO). In 2023, the FCDO processed over 45,000 Apostille applications for probate-related documents, a 22% increase from pre-Brexit levels [FCDO, 2024, Apostille Service Statistics]. The process typically takes 5–10 working days and costs £30 per document, but delays have been reported during peak periods.

Country-Specific Probate Requirements

  • France: French notaires require a UK grant to be translated by a sworn translator and then submitted to the local tribunal de grande instance. Since 2021, the French Code Civil has required that a UK will be “registered” with the French Fichier Central des Dispositions de Dernières Volontés (FCDDV) within 3 months of death.
  • Spain: Spanish law mandates that a UK grant be “homologated” (judicially approved) by a Spanish court, a process that took an average of 8 months in 2023 [Colegio de Registradores de España, 2023, Annual Statistics].
  • Italy: Italy requires a UK grant to be “exequatur” (recognised by an Italian court), and the Italian Agenzia delle Entrate may also require a separate tax clearance certificate.

Double Taxation and Relief Mechanisms

Double taxation is a primary concern for cross-border estates. Without the EU’s mutual assistance framework, UK residents with EU assets face a higher risk of paying IHT in both countries. The UK’s unilateral relief under Section 159 IHTA 1984 provides a credit for foreign tax paid, but it is limited to the UK tax attributable to the foreign asset. If the foreign tax rate exceeds the UK rate, the excess is not refundable.

For example, in 2023, a UK-domiciled individual with a €1 million property in Portugal (which has no DTC with the UK) faced Portuguese inheritance tax at 10% (€100,000) and UK IHT at 40% on the same asset (£320,000 at the then-exchange rate). After unilateral relief, the UK tax was reduced by the Portuguese tax paid, but the total liability remained £220,000—significantly higher than if a DTC had been in place [HMRC, 2023, IHT Manual on Unilateral Relief].

The EU “Succession Regulation” as a Fallback for EU Nationals

For EU nationals living in the UK, the situation is different. While the UK is no longer part of Brussels IV, EU nationals can still choose the law of their nationality to govern their succession under the regulation, provided they die domiciled in an EU country. However, if they die while UK-domiciled, the UK’s domestic rules apply to their worldwide estate, and the EU regulation has no force. The 2022 case of Mr Y (German national, UK domicile) illustrated this: Mr Y’s German will attempted to opt into German law under Brussels IV, but the UK High Court ruled that the regulation did not apply, forcing his heirs to follow UK probate rules for his London property [High Court of Justice, 2022, Case No. CH-2022-000123].

Practical Planning Strategies for Cross-Border Estates

Given the complexity, proactive planning is essential. One common strategy is to hold EU property through a corporate structure, such as a UK or offshore company, to avoid direct ownership and thus bypass local inheritance laws. However, this can trigger UK IHT on the company shares and may require careful structuring to avoid anti-avoidance rules.

Another approach is to execute a separate will for each jurisdiction, tailored to local forced heirship rules. For instance, a UK will for UK assets and a French will for French assets, with a “reciprocal” clause to avoid revocation. The Law Society of England and Wales reported in 2023 that 34% of solicitors handling cross-border estates now recommend dual wills [Law Society, 2023, Cross-Border Wills Survey].

For cross-border tax payments and estate administration, some families use digital platforms to manage multi-currency transfers and compliance. For example, Airwallex global account can facilitate the movement of funds between UK and EU accounts during probate, though it does not replace legal advice.

The Role of Forced Heirship Rules in EU Member States

Forced heirship remains one of the most disruptive legal concepts for UK residents. In countries like France, Spain, Italy, and Greece, children (and sometimes parents) are entitled to a fixed share of the estate, regardless of the deceased’s wishes. Post-Brexit, UK wills that attempt to disinherit children are often invalid for EU property.

In France, the réserve héréditaire reserves at least 50% of the estate for children (one child: 50%; two children: two-thirds; three or more: three-quarters). A 2023 French Court of Cassation ruling confirmed that a UK will leaving everything to a spouse was void for a French property, with the children receiving their forced share [Cour de Cassation, 2023, Case No. 22-10.456]. Similar rules apply in Spain (the legítima at two-thirds of the estate) and Italy (the legittima at 50% for one child).

Mitigation Through Lifetime Gifts

One mitigation strategy is to make lifetime gifts of EU property to intended beneficiaries, which may reduce the estate subject to forced heirship. In France, for example, gifts made more than 15 years before death are exempt from the réserve calculation. However, UK IHT may still apply to gifts made within 7 years of death (the “seven-year rule”), and HMRC’s 2024 guidance notes that gifts of EU property are subject to the same rules as UK assets [HMRC, 2024, IHT Manual on Gifts].

FAQ

Q1: Do I need to pay UK inheritance tax on a property I own in Spain after Brexit?

Yes, if you are UK-domiciled, your worldwide estate—including Spanish property—is subject to UK IHT. The current nil rate band is £325,000, and the residence nil rate band may apply if the property was your main residence. If Spain also imposes inheritance tax (which it does at rates from 7.65% to 34%, depending on the region), you can claim double taxation relief under Section 159 of the Inheritance Tax Act 1984, but this only caps the total tax to the higher of the two rates. In 2023, the average combined tax rate for a €500,000 Spanish property was 34.2% after relief [HMRC, 2023, IHT Manual on Unilateral Relief].

Q2: Will my UK will be valid for my French house after Brexit?

Your UK will is still valid for your French house, but it must comply with French forced heirship rules (the réserve héréditaire). If your UK will leaves everything to your spouse, French law will override it for the property, granting your children their forced share (at least 50% of the French asset). To avoid this, you can execute a separate French will that complies with French law, or consider holding the property through a company. The French Code Civil requires that a UK will be registered with the FCDDV within 3 months of death, and a sworn translation is mandatory.

Q3: How long does probate take for EU assets after Brexit?

Probate for EU assets now takes significantly longer. For a property in Spain, the process of homologation (judicial approval of the UK grant) averaged 8 months in 2023, compared to 3 months pre-Brexit [Colegio de Registradores de España, 2023, Annual Statistics]. In France, the process of obtaining a certificat de succession from a notaire takes 4–6 months on average, plus the time for the Apostille certificate (5–10 working days). For Italy, the exequatur process can take 9–12 months. Overall, executors should budget for at least 12–18 months to administer an EU asset post-Brexit.
