For foreign investors in Korea, we are your ideal local partner-combining international
quality standards with in-depth local market expertise.

Every day, somewhere in the world, tax and financial regulations and treaties change. Strategies that reduced taxes yesterday may not work today. New opportunities to save money could be missed – especially as you enter new markets. The talented staff in your organization might not have time to keep up with each nuance. Your current advisor may think your company is too small for personal attention, or they may simply be too small to serve you.

Successful companies consider tax and financial implications before they make business decisions, so they do not have to pay more than their legal obligation. This makes international corporate compliance, consulting, and structuring a crucial element in your global strategy.

As a leading tax advisory and BPO service firm in Korea, our professionals, with in-depth knowledge of tax, accounting, commercial law, and related regulations, provide high-quality tax and BPO services. In particular, we specialize in BPO services and tax-related matters, including tax audits, tax appeal, M&A tax consulting, international tax advice on cross border transactions, and transfer pricing for multi-national companies.  In addition, based on our extensive experience with various tax projects, we maintain close collaboration with governmental bodies in Korea (e.g., the National Tax Service, the National Pension Service, the National Health Insurance Service, the Ministry of Strategy and Finance, the Tax Tribunal, etc.).  

As tax and financial matters grow increasingly important, we listen to our clients’ needs and actively pursue tailored solutions. Our client-focused service will enhance the value of your business.

In today's interconnected world, companies are increasingly deploying employees across international borders. This can be for short-term projects, long-term assignments, or permanent relocations. While this global expansion offers significant opportunities, it also creates complex tax challenges. This is where Global Mobility Tax Services play a vital role, providing essential support to both businesses and their mobile employees.

Global Mobility Tax Services are specialized consulting and compliance solutions designed to manage the tax complexities that arise from international employee assignments. The primary goal is to ensure tax compliance for both the company and its employees across all relevant jurisdictions. These services go far beyond simple tax filing; they encompass a holistic approach to managing the financial and administrative aspects of a global workforce.

Global Mobility Tax Services provide a range of critical functions:

  • Tax Planning & Strategy: Before an employee moves, these services help companies and individuals develop a tax-efficient plan. This includes advising on assignment structures, compensation and benefits, and understanding the tax implications in both the home and host countries.
  • Tax Compliance & Filing: This is the core function. Tax professionals prepare and file personal income tax returns for employees in multiple countries, ensuring all reporting requirements are met. This often involves navigating complex tax treaties and understanding foreign tax credit mechanisms to prevent double taxation.
  • Compensation & Payroll: They work closely with payroll teams to ensure that a mobile employee's salary and benefits are taxed correctly. This can involve split payrolls, where an employee is paid in two currencies and managing tax withholdings in multiple locations.
  • Tax Equalization & Protection: A key service is managing tax equalization, a common policy where a company ensures an employee's tax burden on assignment is neither more nor less than what it would have been had they remained in their home country. This protects employees from unexpected tax liabilities and provides cost predictability for the company.
  • Advisory & Consulting: Beyond compliance, these services offer ongoing advice on immigration, social security agreements, and the tax implications of different types of assignments (e.g., business travel vs. long-term assignments). They also provide advisory support for remote work arrangements.
