German Federal Constitutional Court — Inheritance Tax Ruling

What this countdown tracks

Germany's Federal Constitutional Court is expected to rule on 15 June 2026 in case 1 BvR 804/22, a challenge to the business-asset exemptions in the German inheritance and gift tax. The First Senate at Karlsruhe will decide whether the current rules treat heirs of operating businesses unequally compared with recipients of private assets.

Background

The Bundesverfassungsgericht has struck down German inheritance-tax statutes twice before — in 1995 and in December 2014 (1 BvL 21/12) — each time citing violations of Article 3(1) of the Basic Law on equality. Parliament reformed the Inheritance Tax and Gift Tax Act (ErbStG) in late 2016 to preserve the near-total exemption for productive business assets while tightening tests on payroll continuity and asset composition. The 2016 reform introduced a distinction between "preferred" and "administrative" assets within a business, with exemptions scaled by workforce retention over five to seven years and capped for estates above €26 million.

Case 1 BvR 804/22 originates from a constitutional complaint filed by a taxpayer who inherited private wealth and challenges the ongoing privilege for business heirs. The CMS Germany legal brief published in January 2026 listed the case among the year's most consequential pending rulings, noting that the First Senate has scheduled its decision for mid-June 2026. A broad striking-down could force the Bundestag to rewrite the ErbStG for the third time in three decades and could reopen political debate over wealth taxation, which the SPD and Greens have sought to reintroduce. Germany is one of the few OECD economies without an annual wealth tax since the Bundesverfassungsgericht effectively suspended the Vermögensteuer in 1995 on similar equality grounds.

Revenue stakes are significant: German inheritance tax generates roughly €11 billion annually, but current business exemptions shield tens of billions in transferred operating capital from the levy each year. Academic estimates from the DIW Berlin institute put aggregate untaxed business transfers at above €50 billion annually at the height of the Mittelstand succession wave of 2015–2025.

Why the date matters

15 June 2026 is the publication date indicated in the First Senate's 2026 case list and matches the calendar identified in industry trackers. The ruling follows several years of preparatory proceedings and oral arguments; Karlsruhe decisions on tax equality typically trigger 18- to 24-month legislative transition periods, as seen after the December 2014 ruling which gave Parliament until June 2016 to reform. A ruling on this date would hand the matter to the Merz-Klingbeil Bundestag government well ahead of any 2027 budget cycle.

What to watch for

• Whether business-asset exemptions are struck down in whole or in part.
• Transition period granted to the Bundestag for remediation.
• Impact on family-firm succession planning for the German Mittelstand.
• Finance Ministry statements on revenue implications after Federal Ministry of Finance forecasts.
• CDU-SPD coalition response and draft ErbStG amendment timetable.
• Länder reactions via the Bundesrat tax committee, with Bavaria historically defending exemptions.
• Any dissenting minority opinions from the First Senate.
• Market reaction in listed family-controlled companies including BMW, Merck and Henkel.
• Interaction with EU state-aid rules if differential treatment is retained.

Economic stakes

Germany has roughly 3.3 million Mittelstand businesses, many approaching generational transfer in the late 2020s. KfW's 2024 succession survey estimated 560,000 company handovers through 2027, with more than €600 billion in business equity changing hands. A restrictive Karlsruhe ruling could expose a significant share of those transfers to inheritance tax at the standard 30 per cent rate applied to related parties, or up to 50 per cent for non-relatives. Family-firm associations including Die Familienunternehmer have lobbied for full preservation of the exemption; trade unions and the DIW institute argue distributional fairness demands its curtailment. The ruling will directly shape family-office formation, foundation structures and corporate reorganisations in the second half of the 2020s.
