Overview
- The Bundesfinanzhof, which ruled on Wednesday May 20, 2026, dismissed the lawsuits and found the Baden‑Württemberg law compatible with the Basic Law and the state constitution.
- The state's "Bodenwertmodell" bases tax on two factors only—plot size and the local Bodenrichtwert, a zone average set by local appraisal committees—so buildings and rental income are largely ignored.
- About 5.6 million property owners in Baden‑Württemberg are directly affected and many tenants may feel the impact because landlords commonly pass the tax on via service charges.
- The court stressed that the law favors mass applicability over perfect precision, leaving limited correction routes for owners who must produce costly expert appraisals that show more than a 30% difference at their own expense.
- The decision ends this central Baden‑Württemberg case but leaves other state models to be reviewed next by the BFH and prompts supporters of the plaintiffs to signal a likely constitutional complaint in Karlsruhe.
