Can South Korea successfully levy taxes on the income generated locally by global tech giants? Although tax authorities have slapped multinational companies like Big Tech corporate tax targets Google, Netflix, and Meta with substantial corporate taxes over the past few years, the courts have consistently ruled to cancel these assessments.
Legal Battles and Court Rulings on Big Tech Taxes
According to the legal community, the Supreme Court’s Special Division 2 has finalized a lower court ruling in favor of Google Korea, dismissing a roughly 154 billion won corporate tax collection notice imposed by tax authorities.
Taxation on the local income of foreign big tech subsidiaries generally falls into two categories. First, royalties—payment for the use of intangible assets such as copyrights and trademarks—are subject to domestic withholding tax. Second, business income corresponding to operating profits earned by foreign entities from advertising sales and service provisions can only be taxed if a domestic permanent establishment exists. Consequently, tax authorities have typically argued that these revenues constitute either royalty income or business income tied to a fixed establishment, assertions that tech giants have fiercely contested.
Tax authorities targeted Google Korea in 2020 for corporate and local income taxes, taking issue with the fact that the company remitted a portion of its domestic advertising revenue to Google Asia Pacific as advertising resale commissions. Google Korea utilizes ad inventory secured from this Singapore-based regional headquarters to sell to domestic advertisers. The tax authority argued this revenue constituted taxable royalty income derived from Google’s copyrights and know-how.
Google Korea countered that the income was the business income of Google Asia Pacific and filed an administrative lawsuit. In January of last year, the first-instance court ruled in favor of Google Korea, noting that the subsidiary lacked physical facilities for advertising services and that the actual provider was Google Asia Pacific. The second-instance court upheld this judgment in May, which was finalized through the Supreme Court’s dismissal of the appeal without further review.
Similarly, Netflix Services Korea won a partial victory in April in its first-instance lawsuit to cancel a corporate tax imposition. Tax authorities had slapped Netflix Korea with an 800 billion won corporate tax bill in 2021 regarding fees paid to overseas entities like its Netherlands headquarters, arguing they were royalties for domestic reproduction and transmission rights. The court ruled to cancel 762 billion won, stating that Netflix Korea merely acts as a service mediator.
In May, Meta, the parent company of Facebook, also secured a partial victory in its first-instance corporate tax lawsuit. While tax authorities claimed Facebook Korea maintained a domestic permanent establishment based on its ad sales operations, the court ruled that Meta’s Irish entity held no disposal or usage rights over a Korean business establishment, siding with Meta instead.
The Reverse Discrimination Debate and Future Outlook
The controversy surrounding taxation on overseas big tech firms continues globally. Domestically, critics point out a sense of reverse discrimination when compared to the massive corporate taxes paid by local IT firms. According to Google audit reports, its three domestic entities paid 28.3 billion won in corporate taxes last year, a stark contrast to domestic giants like Naver (528 billion won) and Kakao (170 billion won).
An anonymous former big law attorney noted that the fundamental issue lies in the traditional tax system being designed around physical fixed establishments like factories, making it difficult to apply standard criteria to online businesses that lack physical footprints. Another former large law firm attorney stated that the legal framework makes it structurally challenging for domestic authorities to exert enforcement power over foreign companies.
While European countries like France operate a digital services tax that levies fees on revenues generated domestically by multinational corporations, such measures face significant headwinds, including threats of retaliatory tariffs from the United States. Experts suggest that while fundamental changes to outdated tax treaties are necessary, the National Tax Service must also continue its efforts to pinpoint enforceable tax opportunities.
