Taiwan: Guidance on foreign currency gains and losses, earnings declarations

Guidance issued by the National Taxation Bureau

December 2, 2025

The National Taxation Bureau recently issued the following tax-related guidance:

  • Unrealized exchange gains or losses from year-end foreign currency valuations must be excluded from profit-seeking enterprise income tax returns. Only realized amounts are deductible under Articles 29 and 98 of the relevant regulations.
  • Companies may use current-year surplus earnings to offset past losses when declaring undistributed earnings, including losses incurred before 1997. This addresses misconceptions about the scope of offsets under the 1998 declaration requirements.
