Leaving South Korea: What to Know
Tax Departure Rules for South Korea
South Korea does not impose a formal departure or exit tax on individuals. However, unrealised gains on certain overseas financial accounts may be scrutinised under FBAR-style reporting obligations. You must file a final year tax return covering income up to your departure date.
Capital gains considerations: South Korea taxes capital gains on Korean real estate and shares in Korean companies. Non-residents are still liable for Korean-source capital gains at rates from 20-25%. Shares in listed Korean companies held by non-residents are generally exempt if the holding is below 25%.
Practical steps when leaving: Deregister from your local district office (dong/myeon), file a final income tax return with the NTS, and appoint a tax agent if you have ongoing Korean-source income. Cancel your National Health Insurance enrolment upon departure.
