Minimum corporate tax
From the 2025 period, corporate tax cannot be less than 10% of corporate income before deductions and exemptions. Some exemptions (e.g. participation income, R&D, investment incentives) can be deducted in this calculation. Even loss-making companies may face the minimum tax if they have accounting profit.
