l 2019 Individual Income Tax Return Filing Deadline (due by June 1, 2020)
Residents, regardless of their nationalities, are subject to Korean income tax based on worldwide income including global income (employment income, business profits, dividend, pension, interest, rental, and other miscellaneous income), severance pay and capital gains. However, under the revised Individual Income Tax Law (IITL), in the case where the period that a foreigner, who is a tax resident of Korea, has his address or abode in Korea does not exceed 5 years in aggregate during the past 10 years from the end of the concerned tax year, his/her foreign source income earned from January 1, 2009 shall be taxed in Korea only if such income is paid in Korea or such income is remitted into Korea.
Taxpayers making monthly tax payments and having only one source of worldwide income (i.e., either Class A or Class B) are generally not required to file a global income tax return since the employer (for Class A income earners) or the Class B taxpayers' association (for Class B income earners) finalizes the individual's tax liability at the end of the year. Taxpayers having more than one source of income, however, are required to file a global income tax return for the year and pay taxes due on such income on or before May 31 of the following year, or prior to permanently leaving Korea.
The filing of 2019 annual individual income tax return is coming due on June 1, 2020 together with necessary tax payments.
