Taiwan Update: Treaties, Tariffs and Top-Up Tax Turbulence 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Paulson Tseng, PwC Taiwan’s International Tax Services and Transfer Pricing Leader, the firm’s Human Capital Leader, and host of the Finance and Tax Cafe podcast.

Doug and Paulson discuss Taiwan’s corporate tax framework, including the 20% corporate rate, foreign tax credit limits, withholding tax friction for services, and CFC rules; how inbound investment remains strong in semiconductors and R&D while outbound models are shifting toward more diversified, multi-nodal footprints; Taiwan’s current Pillar Two posture, top-up tax exposure, and readiness challenges around data, education, and compliance; whether Pillar Two is already changing business behavior; tax controversy themes in Taiwan, especially transfer pricing, withholding tax, and risk-based audits; and Paulson’s own podcast and its broader finance, economic, and workplace-stress topics.
