Supreme Court rules foreign brokerage fees exempt from education tax

The Supreme Court ruled on February 12 that a domestic securities firm does not owe education tax on commission fees distributed to an overseas affiliate when jointly mediating financial investment transactions. The decision establishes that such amounts fall outside the taxable revenue base defined under former regulations.

The dispute centered on whether a local member of an international investment group could exclude half of its brokerage fees from its education tax calculation after passing them to a foreign related company. The firm had executed orders from overseas clients for products listed on the Korea Exchange and remitted half of the collected commissions to its partner abroad, treating the payment as a non-taxable distribution for joint mediation services.

Tax authorities rejected this treatment, arguing the transferred funds were payments for support services rather than shared mediation fees, and issued a corrected tax assessment. The Supreme Court dismissed the claim, finding that the foreign affiliate performed substantive mediation activities by soliciting orders and facilitating trades.

Under the Education Tax Act prior to its revision on December 31, 2019, financial and insurance operators pay taxes based on revenue including interest, dividends and commissions. However, enforcement decrees stipulate that if a firm jointly mediates financial investment products with another company and distributes a portion of the fee, that share is excluded from the taxable amount.

The justices clarified that the term "other company" in the relevant decree is not limited to domestic entities licensed by the Financial Services Commission. The scope extends to foreign investment traders or brokers legally authorized to conduct equivalent business in their home jurisdictions.
