The Ministry of Finance (MOF) reminded all profit-seeking enterprises that the interim tax filing and payment period for the 2026 tax year runs from 1 to 30 September 2026. Under Article 38 of the Income Tax Act, companies with a fiscal year ending 31 December must calculate interim tax based on either half of the previous year’s final tax liability or the actual operating results for the first six months of the current year, whichever is lower. The payment must be made via designated financial institutions or electronic tax payment platforms. Late filing incurs a penalty of 1% of the tax due per two days of delay, up to a maximum of 15%.
Key Takeaways
- Dual Calculation Option: Taxpayers may choose the more favorable method: 50% of 2025 assessed tax or actual January-June 2026 profits annualized. The actual profit method requires certified financial statements if the interim tax exceeds NT$500,000.
- Electronic Filing Mandatory: All enterprises with annual revenue exceeding NT$30 million must file electronically through the MOF’s eTax portal. Paper returns are accepted only for smaller entities with prior approval.
- Credit Carryforward: Interim tax paid is credited against the final 2026 corporate income tax liability due in May 2027. Overpayments are refundable upon final assessment.
