International Tax Services


As businesses and individuals become more connected across borders, international tax issues are becoming more complex and more important to manage correctly. At Lien Phat & Co Tax Advisory, our international tax services are designed to help our clients navigate cross-border tax obligations with clarity and confidence. We work with businesses expanding into overseas markets, foreign investors entering Vietnam, multinational groups managing regional operations, and individuals with international income or assets. Our role is to help our clients understand their responsibilities, reduce unnecessary tax exposure, and structure their affairs in a way that supports both compliance and long-term success.

Why International Tax Planning Matters
International taxation involves far more than simply reporting foreign income. Cross-border transactions can trigger multiple tax obligations in different jurisdictions, and without proper planning, businesses and investors may face double taxation, reporting errors, penalties, and missed opportunities for relief. We help our clients take a proactive approach to international tax so they can make informed decisions before issues become costly. Our international tax advice helps support:
  • Efficient cross-border structuring
  • Management of double taxation risk
  • Compliance with local and foreign tax obligations
  • Planning for overseas investments and transactions
  • Improved visibility over international tax exposure
  • Support for long term expansion and growth
We believe effective international tax planning should not only address current obligations but also support broader business and financial goals.


Supporting Businesses Expanding Across Borders

For businesses moving into international markets, tax should be considered early in the planning process. Expansion can create new revenue opportunities, but it can also introduce unfamiliar tax rules, reporting requirements, and risks. We help our clients evaluate how international growth may affect their tax position and what steps can be taken to operate more efficiently. This may involve choosing the right market entry structure, reviewing the tax treatment of contracts and payments, assessing indirect tax implications, or understanding whether local activities create a taxable presence. By planning early, our clients are better positioned to avoid costly restructuring and compliance issues later.


Helping Foreign Investors in Vietnam

Foreign investors entering Vietnam often face questions about entity structuring, tax registration, profit repatriation, and local compliance obligations. We provide guidance that helps investors understand the Vietnamese tax environment and make informed decisions from the outset. Our team supports clients with the tax aspects of establishing and operating investments in Vietnam, including corporate tax matters, withholding tax considerations, and the treatment of cross-border service arrangements. We also help foreign-owned businesses align their local tax obligations with their wider international operations.


Double Taxation and Treaty Relief

One of the most common concerns in international taxation is the risk of paying tax twice on the same income. This can arise when two jurisdictions both claim taxing rights over a transaction, business activity, or individual taxpayer. Tax treaties can often provide relief, but applying them correctly requires careful analysis. We help our clients interpret relevant double tax agreements and determine how treaty provisions may apply to dividends, interest, royalties, capital gains, employment income, and business profits. We also advise on the documentation and structuring needed to support treaty claims where available. Our goal is to help clients manage double taxation risk while maintaining a strong compliance position.

Our Approach to International Tax Services

At Lien Phat & Co Tax Advisory, our approach is practical, strategic, and tailored to each client’s circumstances. No two international tax matters are exactly the same. Tax outcomes depend on where our clients operate, how their entities are structured, the types of transactions involved, and the tax treaties and regulations that apply. We begin by understanding the full picture. This includes the jurisdictions involved, the structure of ownership, the nature of income or transactions, and the short-term and long-term objectives. From there, we identify risks, evaluate planning opportunities, and provide advice that is commercially sound and technically robust. Our international tax services may include:

  • Cross-border tax advisory
  • Double tax treaty analysis
  • Foreign investment structuring
  • Permanent establishment risk assessment
  • Withholding tax planning
  • Transfer pricing support
  • International corporate tax planning
  • Expatriate and individual international tax advice
  • Tax implications of cross-border transactions
  • International tax compliance support

We focus on giving our clients clear advice that can be applied in practice, not just technical interpretations.

Permanent Establishment 

Risk and Cross-Border Activity

Businesses can trigger tax obligations in another country even without setting up a formal subsidiary. In many cases, having people, contracts, or ongoing business activity in another jurisdiction may create what is known as a permanent establishment. This can lead to local corporate tax filings and additional compliance responsibilities. We help our clients assess whether their overseas activities may create a taxable presence and what that means in practice. This is especially important for businesses with regional sales teams, service delivery across borders, remote employees, or contracts negotiated in multiple jurisdictions. Understanding these rules early can help reduce uncertainty and support better operational planning.

Transfer Pricing and Related Party Transactions

For multinational groups and businesses with related party transactions, transfer pricing is a key area of international tax risk. Tax authorities increasingly expect businesses to show that intercompany transactions are priced on an arm’s length basis and supported by proper documentation. We advise clients on transfer pricing considerations for management fees, service arrangements, financing, intellectual property use, and other intercompany dealings. Our support includes reviewing transaction structures, identifying areas of risk, and helping clients prepare for compliance obligations. Strong transfer pricing planning can reduce the risk of disputes, adjustments, and penalties.

International Tax Services for Individuals

International tax issues do not only affect companies. Individuals who work, invest, or hold assets across borders may also face complex tax questions. We assist expatriates, foreign professionals, investors, and internationally mobile individuals in understanding their tax obligations and planning appropriately. This may include advice on tax residency, employment income, foreign-sourced income, capital gains, reporting requirements, and the tax treatment of overseas assets. We help our clients make sense of how different rules interact so they can manage their affairs with greater confidence.

We aim to support both immediate compliance and long-term tax efficiency. When international tax is managed proactively, our clients are in a stronger position to grow, invest, and operate with confidence.
