International Tax Cooperation
The LCITA and its enforcement decree accept the general principle that income classification under a Korean tax treaty takes priority over that of the domestic tax law.

Under the LCITA and its enforcement decree, the Korean tax authority may request the tax authority of a treaty partner to collect the Korean taxes, subject to any limitations provided for in the treaty. Similarly, if the treaty partner requests the Korean tax authority to cooperate in collecting its taxes from a Korean resident, the Korean tax authority may collect the treaty partner's tax in accordance with the procedure for the collection of national taxes provided in the National Tax Collection Law.

The Korean tax authority may exchange tax information with foreign countries with which Korea has entered into tax treaties, subject to the provisions and limitations of the tax treaties.

If necessary, the Korean tax authority is permitted to 1) simultaneously conduct a tax audit with foreign tax authorities, under the convention for cooperation in tax administration with that foreign country or 2) dispatch Korean tax officials to the foreign country to conduct a direct tax audit of the company in that country.

As of May 2006, Korea has entered into bilateral tax treaties (Conventions for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income and capital) with 65 countries. In addition to the primary objective of avoiding international juridical double taxation, tax treaties serve purposes such as promoting the introduction of advanced technology and capital from abroad, as well as encouraging business expansion of domestic companies in foreign countries.
