A Seoul court ruled Friday that the state tax office refund Lone Star Funds 119 billion won ($117 million) in taxes collected from the U.S. buyout fund in its sale of a stake in Korea Exchange Bank.

In June 2007, Lone Star, which bought KEB in 2003, sold part of its stake in the lender for 1.19 trillion won via a block sale.

Local tax authorities withheld 10 percent of the sale proceeds in capital gains taxes. Challenging the taxation, LSF-KEB Holdings, Lone Star's subsidiary, filed a lawsuit.

The Seoul Administrative Court said a capital gains tax should be levied on an actual beneficiary of the proceeds of the sale, saying that the gains eventually belong to U.S.-based Lone Star, not its affiliate in Belgium.

Lone Star claimed that the tax should be exempted since the actual seller of KEB was based in Belgium, with which South Korea has a double-taxation avoidance deal. Belgium exempts taxes on income from overseas equity investments.

In this case, the U.S.-based Lone Star Funds did not have a duty to pay taxes in Seoul, according to the court.

A tax treaty signed between Seoul and Washington stipulates that a resident living in one country is exempted from taxation by the other nation in cases including stock sales.

Korea's tax authorities claimed that Lone Star had a duty to pay taxes to Seoul as it had been running its business for a long period of time and made a significant amount of capital gains here.

Lone Star exited from the Korean market when it sold its entire 51.02 percent stake in KEB to Hana Financial Group in 2012. But the tax row involving Lone Star still lingers as the company has been frequently criticized here for pocketing a huge amount of profits and exiting the country without paying taxes. (Yonhap)
