The United States has 66 bilateral income tax treaties in place. Under these treaties, residents (not necessarily citizens) of foreign countries are generally taxed at a reduced rate or are exempt from U.S. tax on some items of income they receive from sources within the United States.

The United States has 66 bilateral income tax treaties in place. Under these treaties, residents (not necessarily citizens) of foreign countries are generally taxed at a reduced rate or are exempt from U.S. tax on some items of income they receive from sources within the United States. Similarly, residents (or, sometimes, nonresident citizens) of the United States are generally taxed by the treaty partner country at a reduced rate or are exempt on some items of income they receive from sources within the foreign countries.

The current income tax treaty between the United States and the Republic of Korea was signed on June 4, 1976, and entered into force on October 20, 1979. This treaty reflects the economic climates of the two countries at the time of treaty negotiations in the 1970s. Korea was at an early stage of economic development and relied heavily on foreign technology and investment to propel its growth. Like other treaties negotiated by Korea around that time, the U.S. treaty was designed to encourage an infusion of foreign capital into Korea amid its process of economic growth.

Much has changed since the 1970s. Korea has dramatically transformed its economic condition from a nation reliant on foreign resources to a recognized force in the advancement of modern technology and international commerce. 1 The focus of Korean businesses is no longer saturation of local markets, but global expansion. Several Korean companies, including Hanwha, Samsung, Doosan, and LG International, have been ranked by Forbes as among the ''world's biggest public companies.'' On the other side of the Pacific, the United States, while remaining a powerful force in the world economy, is keen on attracting foreign investment and proliferating international commerce through mutual exchange of resources. Just as importantly, as a result of changing economies and the global marketplace, the governments of both Korea and the United States have significantly altered their internal and external policies regarding international taxation and international tax agreements.

Despite these changes, the current treaty has yet to be modified, and as a result, it fails to address the current economic requirements of the two countries. This is generally recognized by both Korea and the United States, and there have been continuing discussions regarding possible negotiations for a new treaty. For example, in March 1998 the U.S. Treasury Department announced that negotiations toward a new treaty would begin at the end of 1998. Negotiations were intended to be based on then-U.S. and Korean model treaties, both of which drew heavily from the OECD model treaty. Negotiations never took place in 1998, however, and 11 years later Treasury has once again announced that the United States will be negotiating with Korea for a new tax treaty, in 2009. 2

In anticipation of those negotiations, this article examines certain provisions of the current treaty and suggests possible amendments based on the 2006 U.S. model treaty and the 2008 OECD model treaty. It also examines additional provisions that might be added to the new treaty to prevent abusive transactions and to encourage mutual exchange of information. The article is not intended to provide a comprehensive analysis of all possible amendments to the current treaty, but rather to encourage Korea and the United States to negotiate, and perhaps to serve as a platform for the initial consideration of amendments.

I. Ability to Tax

The relationship between Korea and the United States is intricate but exceptionally important for both countries. Over time, the countries have developed into major social and economic partners. Since the early 1980s, the number of Koreans living in the United States has grown immensely. Before 1980, there were approximately 248,920 Koreans living in the United States as citizens or residents. 3 By the end of 2007, there were approximately 1.4 million Korean- Americans living in the United States, 4 with an additional 1,028,253 Koreans temporarily residing in the United States as students, employees, tourists, or for other purposes. 5

International commerce between the countries has also grown substantially. Over the past 10 years, the trading relationship between the United States and Korea has nearly doubled. 6 Exports and imports between the countries amounted to around $48 billion in 1998 with a fairly even trade balance. 7 By 2008, trade conducted between the countries amounted to over $82.8 billion, with the trade balance in favor of Korea. 8 Many large companies in Korea (including various divisions of LG International, Samsung Group, and Hyundai Group) also maintain substantial connections to the United States, generally operating their U.S. businesses through local branches, subsidiaries, or affiliates.

Similarly, many U.S. multinational companies (including General Electric Co., Microsoft, Citigroup, and J.P. Morgan Chase & Co.) maintain extensive operations in Korea through local branches, subsidiaries, or affiliates. In light of the substantial interaction between the United States and Korea, it will be important for the revised treaty to clearly define and limit the taxing rights of the two countries. In particular, the revised treaty might provide more refined definitions of treaty terms, including ''corporation'' (particularly what constitutes a ''head or main office'' to qualify as a Korean corporation), ''resident,'' ''industrial or commercial activity,'' ''international traffic,'' and ''pension.'' Also, the revised treaty might consider the following amendments to taxing rights.

A. Capital Gains

Under the current treaty, the source country's ability to tax capital gains is generally limited to gains derived from the sale of real property located in that country. Capital gains from the sale of capital assets other than real property, including stock, can only be taxed by the taxpayer's country of residence, unless the gain can be attributed to a permanent establishment in the source country or the taxpayer maintains a fixed base in the source country or otherwise remains in the source country for a specific period during the tax year. Thus, article 16 of the current treaty provides that a resident of one country will be exempt from tax by the other country on gains from the sale, exchange, or other disposition of capital assets, unless:
