The Ministry of Finance announced that the interim filing period for 2026 (Year 115 of the Republic of China) Profit-Seeking Enterprise Income Tax will commence on September 1, 2026, and run through September 30, 2026. All profit-seeking enterprises with a fiscal year ending December 31 must file interim returns based on the first half of the year’s operations. The MOF reminded taxpayers to utilize the electronic filing system and highlighted key changes including adjusted tax credit limits for R&D expenditures and updated estimated tax payment safe harbor rules.
Key Takeaways
- Mandatory Electronic Filing: All enterprises must file via the MOF’s e-filing portal; paper returns are no longer accepted except for specifically approved exceptions.
- R&D Tax Credit Adjustments: The interim filing must reflect the revised cap on R&D tax credits (now 30% of current year tax liability, up from 20%) per the 2025 Statute for Industrial Innovation amendments.
- Estimated Payment Safe Harbor: Enterprises paying 100% of prior year’s tax liability (or 90% of current year’s estimated liability) avoid underpayment penalties, providing certainty for cash flow planning.
