Corporate tax (also called corporation tax or company tax) is a direct tax levied on the net profits of a company or corporation. It is calculated on taxable profit — which is revenue minus allowable business expenses and deductions — rather than on total turnover.
Most countries apply a single flat corporate tax rate, though some differentiate between large companies and SMEs. A growing number of countries have also adopted a minimum effective corporate tax rate under the OECD Pillar Two global minimum tax agreement (15% for multinationals with revenue over €750M).
