Taiwan: Taxpayers Must Act Within the 30-Day Rights Protection Window

As of 2026/08/18, tax authorities reminded taxpayers of the critical 30-day window following issuance of tax assessments, notices of deficiency, or decisions on appeals, during which individuals and businesses may file objections, request reviews, or initiate payment arrangements to protect their legal rights. Failure to act within this statutorily defined period may result in the waiver of the right to contest the tax determination, the accrual of additional penalty interest, and the initiation of enforcement proceedings, including asset seizure or bank account levy. The Ministry of Finance emphasized that the 30-day period applies uniformly across various tax categories, including corporate income tax, value-added tax, and special consumption tax, and that taxpayers are strongly encouraged to seek professional tax advisory assistance to navigate the review process effectively. Additionally, the guidance outlines the procedural steps for filing, the evidence required to support objections, and the expected timelines for tax authority responses, aiming to reduce misunderstandings and ensure that taxpayers fully exercise their procedural rights within the prescribed timeframe.

Key Takeaways

  • Mandatory 30-Day Period for Taxpayer Objections: Taxpayers must file objections or request reviews within 30 days of receiving tax assessments or deficiency notices to preserve their right to contest the decision.
  • Consequences of Missed Deadlines: Failure to act within the 30-day window may lead to the forfeiture of appeal rights, accrual of penalty interest, and initiation of enforcement actions such as asset seizure or bank levy.
