Corporate Tax:

A corporate tax is a tax on the profits of a corporation. The taxes are paid on a company's taxable income, which includes revenue minus cost of goods sold (COGS), general and administrative (G&A) expenses, selling and marketing, research and development, depreciation, and other operating costs.
Corporate tax rates vary widely by country, with some countries considered to be tax havens due to their low rates. Corporate taxes can be lowered by various deductions, government subsidies, and tax loopholes, and so the effective corporate tax rate, the rate a corporation actually pays, is usually lower than the statutory rate; the stated rate before any deductions.
