Tax Health Check for Taiwan Companies
📑 Table of Contents
Corporate Tax Risk & Compliance Assessment
As companies scale, expand cross-border operations, or engage in related-party transactions, tax risks often accumulate quietly within day-to-day operations. Due to the fact that in Taiwan, the National Taxation Bureau can audit tax filings going back 5 to 7 years, and many businesses are exposed to latent tax liabilities without realizing it. Issues are usually discovered only when audits arise, incentives are denied, or transactions are challenged.
LY CPA Firm provides a corporate-focused Tax Health Check for Taiwan companies, helping Taiwan-invested and foreign-invested enterprises systematically identify tax risk exposures, compliance gaps, and practical remediation options—before audits, restructurings, or strategic transactions occur.
Our approach delivers institutional-grade tax analysis with a focused, engagement-specific model, suitable for companies seeking rigorous diagnostics without unnecessary overhead.
❓ Why Corporate Tax Health Check Matters in Taiwan
Taiwan’s tax enforcement increasingly focuses on substance over form, cross-border transactions, and intercompany arrangements. Practices that once appeared acceptable may become audit triggers as operations mature.

🧠 Common Issues We've Helped Identify
Real examples from companies like yours.
Over the years, our Corporate Tax Health Checks have uncovered a wide range of issues that could have resulted in audits, penalties, or unnecessary tax payments. Here are a few examples of what we’ve helped our clients catch — before the tax authorities did:
Misclassified service payments to overseas vendors
One client had been paying foreign consultants without applying the correct withholding tax rules. We corrected the treatment and filed for retroactive relief under a tax treaty to avoid future penalties.
Unreported related-party transactions
A multinational had multiple intercompany transactions not properly disclosed or documented. We flagged the issue, helped prepare proper transfer pricing documentation, and reduced the risk of penalties or adjustments.
Overstated input VAT claims
We discovered that several input VAT claims were unsupported due to missing invoices or incorrect use classification. The client voluntarily corrected past filings and avoided fines during a follow-up audit.
Missed investment tax incentives
A fast-growing tech company had qualified for R&D deductions under Taiwan’s tax rules but had never claimed them. We helped file retroactively, resulting in significant tax savings.
Unpaid stamp duty on major contracts
A client signed multiple high-value service and lease agreements but overlooked Taiwan’s stamp tax requirements. We helped assess applicable documents and calculate unpaid tax to avoid late penalties.
Foreign company inadvertently creating a Permanent Establishment (PE)
A foreign enterprise operating through local agents was deemed to have a permanent establishment (PE) in Taiwan, triggering unexpected income tax obligations. We analyzed the potential risk, quantified exposures, and inform the client to manage the risk.
