In 2026 the trade tax multiplier (Gewerbesteuer-Hebesatz) in Germany's 20 largest cities ranges from 410% in Berlin to 537% in Bonn (DIHK survey as at 31 December 2025 and 1 July 2026). On every €100,000 of trade income, that means €14,350 to €18,795 of tax. For a GmbH that lets a supermarket, the multiplier matters only if the extended reduction of the trade-tax base (erweiterte Kürzung) does not apply.
What to check:
• Find out which municipality is entitled to levy the tax, and what multiplier it has set for the coming years.
• Obtain a tax adviser's opinion on the extended reduction for the specific lease before the purchase contract is signed.
• Request an inventory of the assets let together with the building, with a separate list of operating equipment.
• Check that income from electricity, charging and services to tenants stays within the 20% and 5% limits.
