Global income is taxed according to a progressive scale in South Korea and
the level of taxation is considered moderate to high. Income is normally classified
as global income, retirement income or capital gains, all taxed at different
rates.
Global income includes revenue from interest, dividends, property rental,
business or professional income, employment income, and more. Taxable income
is computed as gross income after allowable deductions and exemptions have been
taken into account. Personal income is taxed as per the following list:

Korea has a self-assessment tax system under
which each taxpayer is required to file a tax return
and pay the proper amount of tax by the due date. Tax returns including personal
exemptions and deductions must include supporting documents. Individuals are
required to pay a 10% surcharge on their income tax, which is called the inhabitant
tax. This tax is calculated according to the individual’s income tax liability.
Individuals, including personal companies earning capital gains when selling properties, are subject to capital gains tax at progressive rates. Annual property taxes are imposed at between 0.07% and 4%, depending on location, type of building and so on.
