The effective corporate tax burden on a German GmbH — combining the 15% federal corporate income tax, the 5.5% solidarity surcharge on that tax, and the municipal trade tax — runs to approximately 30 percent in Berlin, 32 percent in Frankfurt and 33 percent in Munich. The trade tax rate varies by municipality and is not deductible against corporate income tax, creating an effective combined burden on profits that has no direct equivalent in most other EU jurisdictions.
A Spanish Sociedad Limitada pays a standard corporate income tax of 25 percent — a single national rate with no municipal equivalent. For newly incorporated companies qualifying under the 2023 Startup Act, the rate is 15 percent for the first two profitable tax years. For small and medium enterprises with annual turnover below €10 million, a transitional reduced rate of 24 percent applies from 2025, declining progressively to 20 percent by 2028.
The differential between operating from Munich (33% effective rate) and operating from Barcelona (25% standard, 15% for qualifying new companies) is not marginal. For a company generating €500,000 in annual profit, the difference between the two jurisdictions represents between €40,000 and €90,000 per year in retained earnings before any distribution.
