Choosing a municipality with a lower Gewerbesteuer multiplier is not inherently unlawful. The risk arises when the registered office on paper does not match the company's real management and operating arrangements.
Companies may choose their location
German company and tax law do not generally require a business to choose the municipality with the highest multiplier. Commercial considerations can include rent, connectivity, access to staff and local tax rates.
Real business activity is the dividing line
A postal address alone does not show that management activity takes place there. Public authorities may examine who makes the important decisions, where records and infrastructure are available and how the location is actually used.
Registered office and place of management are not always identical
The legal registered office and the tax-relevant place of management are related but distinct concepts. The outcome depends on the legal form and facts, which is why company-specific advice is essential.
How to reduce avoidable risk
Use genuinely available facilities, document management activity, keep agreements and booking records, and make accurate statements to registers and authorities. Avoid providers that promise recognition regardless of actual use.
