The owner pays property tax (Grundsteuer) to the municipality: the law names as taxpayer the person to whom the property is attributed when its tax value is assessed (§ 10(1) GrStG). In commercial leases, however, the tenant usually bears the economic burden — if the lease expressly passes the tax on. Without such a clause, the tax stays with the landlord (§ 535(1) BGB).
What to check:
• the lease clause on property tax and on who bears any increase;
• the notices of tax value and of tax under the 2025 reform (request them from the seller), and the municipal multiplier;
• how the purchase contract splits the tax for the year of sale;
• in a vacancy, an application for partial tax relief by 31 March of the following year.
