In 2026, the City of Siegen levies trade tax (Gewerbesteuer) at a multiplier (Hebesatz) of 505% (source: DIHK Hebesatz survey 2026, as of 1 July 2026). 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 Siegen with €50,000 trade income: (€50,000 − €24,500) × 3.5% × 505% = €4,507.13 trade tax.
Under § 35 EStG, sole proprietors and partners can reduce their income tax by four times the trade tax base amount. At a Hebesatz of 505%, €937.13 of the example remains as a real extra cost, provided the income tax on the commercial income is high enough. Corporations such as a GmbH get neither the allowance nor the credit.
Tax advisers based in Siegen belong to the Steuerberaterkammer Westfalen-Lippe. Whether someone is an appointed Steuerberater can be checked in the official register (Steuerberaterverzeichnis) of the Bundessteuerberaterkammer.
