Resident status and income tax in South Korea

Native resident taxpayers are subject to tax on worldwide income while foreign resident taxpayers are only subject to tax on worldwide income if they have stayed for longer than five years during the past ten year period. For foreign resident taxpayers who have stayed for fewer than five years, only Korea-sourced income plus any foreign sourced income that is paid by a Korean entity or transferred into Korea are subject to income tax. Non-resident taxpayers are subject to tax only on income derived from sources within South Korea.

A resident taxpayer can be defined in several ways. The first is as an individual that has had a domicile in Korea or has had a residence within Korea for 183 days or more in a tax year. The second is as an individual that has an occupation that generally requires them to reside in Korea for 183 days or more. The third is as an individual who is deemed to reside in Korea for 183 days or more in a tax year by accompanying family in Korea or by retaining substantial assets in Korea. In other words, even when a person has a job overseas and stays there for more than 183 days in a tax year, they still can be regarded as a resident of Korea if they have their general living relationship, including their family and property, in Korea. For the most part, residency is determined on an individual "facts and circumstances" basis.

A non-resident taxpayer is simply anyone who does not match the definition of a resident taxpayer.
