2018-2020 Korean Corporate Income Tax Brackets : Korean Tax Basics

A tax is imposed on net taxable income in Korea by the district tax office, and cities (or “gu” for large cities). In Korea, a tax payable to the district tax office is called “income” tax (소득세). A tax payable to cities is called “resident” tax (지방세). For most of cases, 10% resident tax will be levied additionally to the income tax.

There are four tax brackets for corporate taxable income in Korea: 10%, 20%, 22% and 25%. The calculation itself is not complicated, as long as the net taxable income amount is accurate.
