New Taiwan-Singapore Tax Treaty to Take Effect in 2027; Tax Authority Highlights 3 Key Points

(Central News Agency, Reporter Lu Yan-ci, Taipei, June 5) The National Taxation Bureau of the Central Area, Ministry of Finance, stated today that the new income tax agreement between Taiwan and Singapore will take effect on January 1, 2027. It reminded profit-seeking enterprises to pay attention to three key revisions in the new agreement: reducing the maximum tax rates on passive income, revising the threshold for determining a permanent establishment, and providing a 3-year transition period for tax credit benefits, in order to adapt and adjust in a timely manner.

The new income tax agreement between Taiwan and Singapore was signed on December 31, 2025, entered into effect on February 13, 2026, and will apply from January 1, 2027.

The Bureau stated in a press release today that the revision primarily references the bilateral economic and trade development, amending the original agreement based on the OECD and UN model tax conventions. It aims to provide more appropriate tax relief and create a more favorable tax environment for bilateral economic, trade, and investment relations.

Regarding the main revision points, the Bureau explained: First, reducing the maximum tax rates on passive income. The new agreement uniformly revises the maximum tax rates for dividends and royalties to 10%, replacing the original agreement's rates of 40% for dividends and 15% for royalties. It also adds a maximum interest tax rate of 10% or provides for tax exemption on interest received by specific entities, helping to reduce the tax cost burden of cross-border trade.

Second, revising the threshold for determining a permanent establishment. The new agreement revises the threshold for a construction permanent establishment from the original "accumulated over 6 months within one year or a total of 6 consecutive months within two years" to "continuously exceeding 9 months." It also adds a threshold for constituting a service permanent establishment as exceeding 183 days continuously or in aggregate within any 12-month period. If an enterprise conducts business through a permanent establishment, the profits attributable to that permanent establishment will be subject to taxation.

Third, providing a 3-year transition period for tax credit benefits. The Bureau explained that the original agreement provided for indirect tax credits and deemed tax credits for the elimination of double taxation. This was to promote bilateral economic development by offering a more favorable tax credit mechanism. Since both Taiwan and Singapore are not developing countries, the credit mechanism should be consistent with other effective tax agreements of Taiwan, and enterprises need reasonable time to adjust to the new system.

Therefore, the new agreement stipulates that these credit mechanisms in Taiwan will lapse three years after the new agreement takes effect, meaning they will only apply to profit-seeking enterprise income tax filings for the years 2027 to 2029. (Editor: Su Zhi-zong) 1150605
