Automated Summary
Key Facts
This case involves Microsoft Corporation and Microsoft Licensing GP seeking a tax refund for corporate income tax withheld by the Daejeon Tax Office. The dispute centers on whether licensing fees paid by Samsung Electronics for Android-based devices between 2012-2015 included payments for non-domestically registered U.S. patents. The lower court dismissed the claim, but the Supreme Court ruled that the lower court failed to properly address whether Microsoft was the rightful claimant under the U.S.-South Korea tax treaty, ordering a retrial.
Tax Type
Corporate Income Tax Withholding on Patent Royalties
Issues
- The court addressed whether it could review new arguments (e.g., inclusion of non-patent rights in the fees) presented by the tax authority during the lawsuit, despite the taxpayer's original claims. It ruled that the court must consider such arguments if they fall within the scope of the original dispute and maintain the identity of the administrative decision.
- The court examined whether the usage fees for patents registered abroad but used in domestic manufacturing (specifically, Android-based smartphones and tablets) constituted domestic-sourced income under the Corporate Income Tax Act and the Korean-US Tax Treaty. The analysis focused on the application of Article 14(4) and Article 6(3) of the tax treaty, which determine the source of income based on the location of patent use. The court concluded that such fees are not domestic-sourced if the patents are not registered in Korea, even if used domestically.
- The court evaluated whether the fees in question could be classified as 'other income' under Article 93(10)(Cha) of the Corporate Income Tax Act, which includes income from copyrights, trade secrets, etc. It found no evidence supporting this classification, affirming that the fees primarily relate to patents and not other income categories.

Holdings
- The court determined that the lower court erred in interpreting the right to request a tax adjustment under the old National Tax Act. It clarified that the parent company (Microsoft Corporation) has the right to claim adjustments for unregistered domestic patent royalties, as the lower court failed to consider the principle of substantial taxation, which requires the tax authority to assess the real owner of the income.
- The court found that the unregistered domestic patent royalties do not qualify as 'other income' under the old Corporate Income Tax Act. It concluded that the contract lacked evidence to support the claim that the fees included non-patent rights (e.g., copyrights, trade secrets) subject to domestic withholding tax.
- The court ruled that the use fees for unregistered domestic patents paid by Samsung Electronics to Microsoft Licensing GP are not classified as domestic-sourced income under the KOR-US Tax Treaty. It emphasized that the treaty's provisions limit domestic-sourced income to rights registered in or used within the contracting states, and no evidence showed such use for the unregistered patents.
Remedies

Legal Principles
The court applied the principle of 'Substance over Form' to determine the tax residency of income derived from patent royalties, emphasizing that the substantial connection to domestic use (rather than formal ownership structures) dictates the source of income for tax purposes. This included analyzing the Han-Me Tax Treaty provisions to assess whether royalties from unregistered foreign patents in Korea constituted domestic source income.

- 미국법인이 특허권을 국외에서 등록하였을 뿐 국내에는 등록되지 않은 경우에는 미국법인이 그와 관련하여 지급받는 소득은 그 사용의 대가가 될 수 없으므로 이를 국내원천소득으로 볼 수 없다.
