Income tax

Residents of South Korea are taxed on their income, whether the income was earned in the country or abroad. Non-residents, on the other hand, are taxed on the income received in South Korea only. Moreover, income tax is deducted at source, and you must file a tax return at the end of each year.

A special tax regime applies to expatriates in South Korea. Their income is taxed at an overall rate of 20.9% made up of 19% income tax and 1.9% local income tax. Certain foreign nationals in South Korea can choose between the flat rate at 20.9% without any deductions or progressive rates between 6.6% and 44% after deductions.

Regarding Korean residents and citizens, the tax rate varies as follows:

Corporate tax

Tax on foreign companies is based on the firm's annual income generated by its permanent establishment. Moreover, a company is taxable on the revenue generated by the transfer of its assets or profits.

The tax rate varies as follows:

Income Tax rate

0 to 200,000,000 KRW 10%

200 million - KRW 20 billion 20%

Certain companies, such as farming and fishing cooperatives and investment companies, may be exempt from tax. However, you may be required to pay other forms of taxes such as urban planning tax, office tax, and more.


Value-added tax (VAT) is applied at a standard rate of 10%. However, export products are exempt from tax. There is also a special excise tax on products containing alcohol and tobacco, as well as on energy, transportation and automotive.

Tax-free system

It is also possible to shop tax-free in South Korea. For example, people with a permanent residence outside South Korea, foreign visitors who do not stay in South Korea longer than six months, as well as South Korean nationals living overseas for more than two years and visit South Korea for under three months, are eligible for tax-free shopping.
