In 2026, the City of Cologne levies trade tax (Gewerbesteuer) at a multiplier (Hebesatz) of 475% (source: City of Cologne). Only commercial businesses pay trade tax, not freelancers under § 18 EStG. Sole proprietorships and partnerships receive a €24,500 allowance on trade income under § 11(1) GewStG. The Hebesatz is applied to the tax base of 3.5% of trade income after the allowance. Example for a sole proprietor in Cologne with €50,000 trade income: (€50,000 − €24,500) × 3.5% × 475% = approx. €4,239.38 trade tax.
