Germany’s corporate tax system will undergo a major overhaul in 2028, though businesses will still face a dense web of surcharges, international minimum tax requirements, and strict anti-avoidance measures—all under heightened scrutiny from tax authorities. As of August 7, 2026, the standard Körperschaftsteuer holds at 15% until December 31, 2027, before dropping to 10%. However, the solidarity surcharge (Solidaritätszuschlag), currently set at 5.5% of corporate tax, inflates the effective rate to 15.825% until the reform takes full effect. Trade tax (Gewerbesteuer) further complicates matters, with municipal rates ranging from 7% to 22% depending on location and profitability.
The basic corporate tax rate will be reduced to 10% in 2028, although the overall tax burden may persist due to additional levies. Germany’s global minimum tax, enforced through the Mindeststeuergesetz, applies to multinational enterprises with worldwide revenues exceeding €750 million in at least two of the four preceding fiscal years. According to the German Minimum Tax Act, this rule applies irrespective of the provisions set out in any double taxation treaty.
Shareholder tax relief depends heavily on ownership structure. For shareholders holding at least 1% of a corporation’s capital within the last five fiscal years, 40% of the profit resulting from the sale of shares or dividends is tax exempt, with the remaining 60% subject to income taxation. If the shareholder is also a corporation, dividends or profits resulting from the sale of shares in a corporation are generally tax exempt for 95% of the respective dividend or profit, with detailed rules and exceptions applying.
A frequently overlooked provision targets German-resident individuals relocating abroad while retaining shares. Under the Foreign Tax Act (Außensteuergesetz), such taxpayers may face a deemed sale of their assets at market value, triggering immediate tax obligations before departure. The rule applies even if the shares are sold later in another jurisdiction, ensuring Germany retains its share of the tax base.
Germany’s Anti-Avoidance Rules and Court Battles
The system’s complexity is matched by its enforcement rigor. Germany’s general anti-abuse rule (Section 42 of the Fiscal Code) nullifies tax arrangements lacking substantial non-tax business purposes. Courts evaluate each case individually, but corporations bear the burden of proving their structures serve legitimate commercial objectives beyond tax reduction.

Tax disputes in Germany follow a punitive process. Corporations have just one month to challenge an unfavorable assessment, and administrative reviews rarely favor taxpayers. If the tax office upholds its position, litigation begins—a process that can drag on for years. The Federal Fiscal Court grants appeals in fewer than 5% of cases, and constitutional complaints succeed in under 1%. Even refund claims face obstacles, as tax authorities offset them against outstanding liabilities, forcing corporations to pursue additional legal proceedings to recover funds.
Global Minimum Tax: Domestic Rules Override Treaties
What distinguishes Germany’s approach is the intersection of domestic rules with global tax standards. Unlike jurisdictions relying solely on treaty networks, Germany enforces its minimum tax provisions domestically—meaning compliance is mandatory, even for foreign multinational groups. While the drop to 10% in 2028 may simplify headline rates, the underlying framework remains a challenge for corporations with cross-border operations or complex shareholder structures.
The first practical tests of the new rates will not occur until 2028, but the dispute-resolution framework is already operational. Current focus remains on audits, objection procedures, and the €750 million revenue threshold, which determines eligibility for the global minimum tax. Whether the reduced rate will offset compliance costs remains uncertain.
Indirect Taxes and Sector-Specific Levies Persist
Beyond corporate and trade taxes, Germany imposes additional levies that vary by sector and asset type. The energy tax (Energiesteuer) applies to fuels like gasoline, diesel, and heating oil, while tobacco, alcohol, and coffee taxes target specific consumables. These are not directly tied to corporate profits but may indirectly raise costs for energy-intensive businesses or producers of taxed goods. These indirect taxes remain unaffected by the 2028 rate reduction but constitute fixed obligations for qualifying corporations.
Germany’s withholding tax regime further complicates cross-border compliance. Dividends paid to non-resident shareholders face a 25% withholding tax, rising to 26.375% when combined with the solidarity surcharge. Interest payments to foreign recipients are taxed at 15%, though reduced rates may apply under tax treaties. Royalties for intellectual property use are subject to a 10% withholding tax, though bilateral agreements can alter this rate. These obligations must be remitted within one month of payment, with late filings triggering penalties. The rules apply universally, ensuring Germany retains tax revenue on cross-border transactions regardless of where the income is ultimately taxed.
