“Resident: Any individuals having a domicile in Korea, having a residence within Korea for 183 days or more in a tax year, or (with effect from tax years beginning on or after 1 January 2026) having a residence within Korea for consecutive 183 days over two tax year periods. Individuals having an occupation that would generally require them to reside in Korea for 183 days or more, or individuals who are deemed to reside in Korea for 183 days or more in a tax year by accompanying families in Korea or by retaining substantial assets in Korea. On the other hand, even when a person has a job overseas and stayed there for more than 183 days in a tax year, but they have their general living relationship, including their family and property, in Korea, they still can be regarded as a resident of Korea.” — National Tax Service (via OECD and PwC summaries of the Individual Income Tax Law)
