Income Tax Treaty between Taiwan and South Korea Affective in 2024

The Taiwan-Korea Agreement for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion, effective January 1, 2024, marks the 35th comprehensive Income Tax Agreement for Taiwan. This agreement, signed on November 17, 2021, facilitates a reduced withholding tax rate to 10% for dividends, interest, and royalties, offering tax exemption for specific business profits and independent personal services. With 29 articles, it provides a robust framework for tax reduction, administrative cooperation, and dispute resolution, enhancing bilateral economic ties.

Under the Taiwan-Korea Agreement, residents of both nations benefit from tax exemptions on business profits in each other’s territories, provided there is no permanent establishment. Additionally, dividends, interest, and royalties are subject to a maximum tax rate of 10%. Dispute resolution mechanisms, such as the Mutual Agreement Procedure, allow residents to address cross-border taxation issues promptly. This agreement strengthens economic collaboration between Taiwan and Korea, fostering industrial resilience and facilitating trade and investment between the two nations.

With Korea being Taiwan’s fifth-largest trading partner and vice versa, the Taiwan-Korea Agreement bolsters economic relations by providing tax certainty and reducing barriers to cross-border trade and investment. By promoting equality and reciprocity, Taiwan’s Ministry of Finance aims to continue signing similar agreements with key trading partners, ensuring comprehensive tax benefits and protection for Taiwanese businesses engaged in overseas investments.

Key Considerations Prior to Applying for the Income Tax Treaty between Taiwan and South Korea

Two crucial factors necessitate careful consideration in the financial planning process. Firstly, it is crucial to ensure that any income considered for applicable benefits is generated subsequent to December 31st, 2023, in order to adhere to relevant regulations and eligibility criteria.

Secondly, prior to enjoying the advantages conferred by tax treaties, it is mandatory to obtain approval from the Taiwan tax authority, thereby ensuring compliance with legal protocols and facilitating seamless utilization of treaty benefits in accordance with established procedures. These pivotal steps underscore the importance of meticulous planning and regulatory adherence in optimizing financial strategies and mitigating potential risks.

How the Income Tax Treaty between Taiwan and South Korea Applies to Businesses

In addition to the opportunity to apply for the reduced withholding tax rate for dividends, interests, and royalty income, business entities have the option to seek tax exemption on the operating profits they accrue within Taiwan. Nonetheless, this privilege comes with specific prerequisites and procedural obligations that must be fulfilled prior to reaping the benefits of the tax treaty. As an illustration, consider a scenario where a Korean business entity seeks to avail itself of the tax exemption on operating profits earned within Taiwan; in such cases, it is important that the entity does not maintain a permanent establishment within Taiwanese territory.

Moreover, it is necessary for the entity to initiate the requisite approval process with the Taiwan tax authority prior to being eligible to enjoy the tax exemption, thereby underscoring how meticulous adherence to regulatory protocols proves to be essential for optimizing tax benefits within the framework of international agreements.

How the Income Tax Treaty between Taiwan and South Korea Applies to Individuals

Individuals are also entitled to benefit from the decreased withholding tax rate applicable to dividends, interests, and royalty income, alongside other provisions within the tax treaty offering tax reductions and exemptions on personal income, including salaries. For instance, previously, a Korean employee dispatched by a Korean firm to work in Taiwan for a duration ranging from 91 to 183 days would have the salary earned during this period considered as Taiwan-sourced income, thereby subjecting it to Taiwan income tax.

However, effective January 1st, 2024, such salaries meeting the criteria outlined in the treaty rules will be exempted from income tax, highlighting the evolving landscape of tax regulations and the significance of adhering to treaty stipulations for individuals seeking to optimize their tax liabilities.

Final Points

The official announcement of the Taiwan-Korea Income Tax Treaty after 7 years of negotiation brought cheer to taxpayers from both parties, enabling them to access treaty benefits on transactions and investments. However, navigating through detailed regulations and complex application procedures is essential. Seeking guidance from a tax advisor before applying for the treaty is strongly recommended.
