Corporate Taxes

Corporate income tax is the tax imposed on the profits earned by corporations, It's a charge levied on a firm’s taxable income, which represents the profit remaining after deducting all allowable expenses from total sales.

Korea has a graduated tax, related to the income : Higher tax rate for higher income.

The marginal tax rate is the rate applied to the next dollar of income.
The average tax rate is calculated by dividing total taxes by total taxable income.

*Average Tax Rate = Taxable IncomeTotal / Corporate Tax = %

For example, a Korean corporation with a taxable income of 30 billion KRW would be taxed as this:

- For the first 200 million KRW, 9 %.

- From 200 million to 20 billion KRW, increases to 19 %.

- For income between 20 billion and 300 billion KRW, 21 % .

Calculating under this system, the total corporate tax amounts to 5.88 billion KRW, giving an average tax rate of approximately 19.6 %

The U.S. applies a flat 21% rate, as per the 2017 Tax Cuts and Jobs Act, since the Trump Administration. It means that all corporate income is taxed at the same rate regardless of its level.
