Google Korea Prevails in 154 Billion Won Tax Dispute

South Korea’s Supreme Court has brought a major tax dispute involving Google Korea to a close by dismissing an appeal filed by the country’s tax authority, judicial officials said Monday. The decision leaves intact a lower-court ruling in favor of the technology company in a case concerning approximately 154 billion won, or $115.3 million, in corporate and local income taxes.

The dispute centered on payments that Google Korea transferred to Google Asia Pacific, a Singapore-based entity. In 2020, the head of Seoul’s Yeoksam Tax Office imposed the taxes after concluding that the transferred income was taxable in South Korea. The tax office treated the payments as royalty income derived from the use of copyrights and know-how.

Google Korea challenged that assessment in court. The company maintained that the payments should instead be classified as business income belonging to Google Asia Pacific. Under that interpretation, the income was not subject to the Korean taxes imposed by the Yeoksam office.

The Seoul Administrative Court accepted Google Korea’s position and ruled against the tax authority. The court found that the payments could not readily be categorized as royalty income. The Seoul High Court later upheld that decision, preserving the cancellation of the tax assessment.

The tax authority then appealed to the Supreme Court. Rather than conducting a substantive review of the lower court’s reasoning, the top court dismissed the appeal on Thursday. That action effectively finalized the Seoul High Court ruling and ended the litigation in Google Korea’s favor.

The case turned on a distinction with significant tax consequences: whether cross-border payments were royalties tied to intellectual property and know-how or ordinary business income of an overseas company. The tax office’s classification supported taxation in Korea, while Google Korea’s classification did not. The courts ultimately found the authority’s royalty characterization insufficient.

The ruling resolves the company’s challenge to the assessment imposed six years earlier. It also underscores the importance of how multinational companies’ cross-border payments are characterized under Korean tax law, particularly when income is transferred to an affiliated company abroad.

The Supreme Court’s dismissal means Google Korea has finally prevailed in the cancellation lawsuit. The approximately 154 billion won tax bill at issue will not be restored through the tax authority’s appeal, and the lower court judgment favoring the company now stands as the final outcome of the case.
