1. Who is a Korean resident?
Americans living and working in South Korea will qualify as residents when they have lived in the country for 183 days or more.

Korean taxpayers report income on a calendar year. Tax returns are due May 31 each year. Residents have to pay half of their global tax by November 30 each year.
5. US-Korea Social Security taxes
In 2011, the US and Korea entered into a Totalization Agreement, which allows expats who work in Korea to be covered under either US Social Security or under the Korean national pension system. Expats pay 4.5% into the national pension if they so choose. There is also a mandatory .55% tax for employment insurance and a tax that ranges from .75% to 22.65% for Industrial Accident Insurance.
