Germany's BOR is the gold standard for business succession relief in continental Europe — but the 2024 Netherlands reform and UK Autumn Budget 2024 both tightened their equivalents significantly
Germany's Betriebsvermögen exemption (ErbStG §13a) remains the most established and comprehensive business succession relief in the EU — 85% or 100% of qualifying business value exempt from inheritance tax, with payroll continuation requirements. The Netherlands BOR (Bedrijfsopvolgingsregeling) was reformed effective 2024: the 100% relief ceiling was raised to €1.325.253 (from ~€1.2m) but the above-ceiling relief fell from 83% to 75% — a net tightening for mid-size businesses. The UK's BPR (Business Property Relief) was fundamentally reformed by the Autumn Budget 2024: previously unlimited 100% relief was capped at £1m, with only 50% relief above — the biggest change to UK business succession in 30 years. These three reforms signal a pan-European trend: governments balancing support for genuine family businesses against concerns about wealthy estate planning.

France's Pacte Dutreil is underused — only 10% of eligible French family businesses use it, despite offering 75% inheritance tax reduction
The Pacte Dutreil (CGI Art. 787B) provides a 75% reduction in the inheritance tax base for qualifying French business transfers — meaning a €10m business creates only €2.5m of taxable value. Combined with the child's €100.000 exemption and 20% rate, the effective tax on a €10m French business transfer to one child is approximately €475.000 rather than €1.800.000. The conditions: a collective commitment of at least 2 years (holding shares and not selling), followed by an individual engagement of 4 years, with one of the signatories managing the business. Despite these accessible conditions, studies show fewer than 10% of eligible businesses use the Pacte — primarily due to lack of awareness among business owners and their advisers.

Italy offers the most generous business succession regime in Europe — 100% exempt with no value cap and only 5-year continuation
Italian law provides complete inheritance tax exemption for family businesses (aziende, società di persone, and controlling shareholdings ≥25% in SRL/SPA) passed to descendants, with no cap on business value and only a 5-year continuation requirement. A family business worth €50m passes entirely tax-free to children who continue running it for 5 years. No other major European economy offers this combination of unlimited relief and short continuation period. France's Pacte Dutreil only provides 75% reduction (not full exemption). Germany's BOR requires complex payroll testing. The UK's BPR is now capped at £1m. Italy's uncapped exemption is unmatched.

ⓘ Business succession reliefs are designed to prevent forced sale of family businesses to pay inheritance tax. The key policy debate: are these reliefs necessary to protect genuine family enterprises, or do they disproportionately benefit wealthy dynasties? The UK's 2024 reform of BPR reflects this tension. Germany has faced repeated Constitutional Court scrutiny. The OECD 2024 report on business succession found these reliefs cost approximately €15-25bn per year in foregone tax across the EU.

ⓘ These calculations use one child as heir and standard exemptions. Real outcomes depend on precise business structure, Verwaltungsvermögen content (Germany), payroll history, and regional rules (Spain). The UK shift from 0% to ~17% effective rate for a £10m business from April 2026 is the most dramatic change in European business succession tax for a generation.

❓ Frequently Asked Questions
Germany's Betriebsvermögen (BOR) relief — under ErbStG §13a — allows qualifying family businesses to pass to heirs with dramatically reduced inheritance tax. Two options: Regelverschonung (85% exempt) requires the heir to maintain aggregate payroll at 400% of the base year amount over 5 years; Optionsverschonung (100% exempt) requires 700% cumulative payroll over 7 years. Qualifying assets include sole proprietorships, partnerships (OHG, KG), and company shares where the deceased held ≥25% (or was party to a shareholder pool). Investment assets (Verwaltungsvermögen) exceeding 50% (Regelverschonung) or 20% (Optionsverschonung) of business value are excluded. For very large businesses (>€26m), individual need assessment applies.
The Dutch Bedrijfsopvolgingsregeling (BOR) provides inheritance tax relief on family business transfers. Under the 2024 reformed rules: 100% relief on the first €1.325.253 of business value (zero tax on this portion), then 75% relief on the remainder (so only 25% of excess value is taxable). Previously: 100% up to ~€1.2m, then 83% above. The heir must continue the business for 5 years — if the business is sold within 5 years, deferred tax becomes due. The BOR applies to active businesses (not investment property or passive holdings) where the deceased held ≥5% for at least 1 year. New anti-abuse rules from 2024 target holding company structures.
The Pacte Dutreil (Code Général des Impôts Art. 787B) provides a 75% reduction in the taxable base for qualifying French company shares transferred by inheritance or gift. Conditions: (1) signatories holding ≥20% (listed) or ≥34% (unlisted) make a collective conservation commitment (engagement collectif) for at least 2 years — agreeing not to sell their shares; (2) each heir then makes an individual conservation commitment (engagement individuel) for at least 4 years after the transfer; (3) one of the signatories manages the company. The 75% reduction applies to the value of qualifying shares — so a €8m shareholding becomes a €2m taxable base. Combined with the children's €100.000 allowance and progressive rates, the effective tax burden is dramatically reduced.
The Autumn Budget of October 2024 fundamentally reformed Business Property Relief (BPR) effective April 6, 2026. Previously: qualifying unquoted business assets received 100% IHT relief — unlimited. Now: 100% relief applies only to the first £1,000,000 of qualifying business assets (combined BPR and Agricultural Property Relief). Above £1m, only 50% relief applies — meaning 50% of excess value is subject to 40% IHT = 20% effective rate above the threshold. A business worth £5m now generates approximately £800,000 of IHT where previously it generated zero. This is being challenged legally by farming groups (APR side) and business owners. The reform is the most significant change to UK business succession taxation since BPR was introduced in 1976.
Italy is objectively the most favourable for large businesses — 100% exempt with no cap and only a 5-year continuation requirement. Germany is excellent for businesses under €26m — 100% via Optionsverschonung with 7-year payroll maintenance, or 85% with 5-year test. Switzerland (Zug/Zurich cantons) has zero inheritance tax for direct family — no specific business relief needed. France's Pacte Dutreil (75% base reduction) is effective but complex. The UK, previously among the best (unlimited 100% BPR), has become significantly less competitive from April 2026. Spain with regional bonifications (Madrid 99%) plus empresa familiar relief (95%) effectively taxes large family businesses near zero. The optimal answer depends on business value, family structure, and where the business operates.
