1. COURSE DESCRIPTION
This course aims to develop advanced level knowledge and skills relating to the Cambodian tax system as
applicable to individuals and companies. The course on basic Cambodian Tax (ACCT 551) is a prerequisite
for this subject as this course aims to leverage the basic tax knowledge gained under ACCT 551 and apply
these into practice and case studies.
This course is also suitable for tax professionals, providing tax services in Cambodia as a tax agent, advisor,
or as an employee handling the tax compliance requirements of the business. There are four main goals:
First, students will use the advanced knowledge gained from the class to make detailed analysis as to what
Cambodian tax(es) applies to non-routine and complex transactions carried out in Cambodia. Second,
students will be able to determine the tax liabilities and how to remit the taxes to the Cambodian tax
authority. Third, students will be able to apply the knowledge gained on making tax planning techniques for
individuals and companies. Fourth, students will be able to analyze and prepare strategies for managing tax
issues, including managing the tax risk during tax audit events.
2. REASON FOR THE COURSE
This course introduces candidates to the subject of taxation and provides broadened and deepened
knowledge and skills relating to Cambodia taxation, as they affect the activities of individuals and businesses.
In this course, candidates are introduced to the rationale behind and the functions of the tax system. The
course then considers the separate taxes that an accountant and consultants would need to have a deeper
knowledge of corporation tax liability withholding tax, and the value added tax liability as well as capital
gain tax, double taxation agreements (DTA), transfer pricing rules, tax audit and protest procedures.
The Cambodian tax system is still developing and personal income tax has been introduced in Cambodia
under 2019 Financial Law but it has not yet been implemented. However, the Capital Gains Tax, which is a
part of personal income tax, will be discussed in detail in this course on how it impacts individuals. In addition,
withholding tax is one of the mechanisms used by the governments of the developing countries to collect
tax revenue from non-tax registered persons, and Cambodia is no exception. However, the withholding
tax rate will be adjusted for residents of countries that have a DTA with Cambodia. In such circumstances,
candidates develop knowledge and skills in regards to “withholding tax as well as tax reductions under
the DTAs”. Furthermore, the course will introduce a transfer pricing method used by the multi-national
companies for related party transactions.
Having covered the core areas and in-depth analysis of the Cambodia taxes, the candidate should be able
to identify tax issues impacting individuals and companies, compute tax liabilities, and manage tax planning
techniques for that individual and companies.
