Guide to Starting a Representative Office in Cambodia 

Unless otherwise indicated, Cambodia representative office stated in this guide refers to a foreign company’s representative office (hereinafter referred to as “RO”) registered in Cambodia, under Cambodia Law on Commercial Enterprise 2005 and the related regulations.


Cambodia is located in the Indochinese peninsula, between Vietnam, Laos and Thailand. By far, the economy of Cambodia is one of the fastest-growing economies in the Southern Asian region. Cambodia is one of the members of the WTO and ASEAN as well as has the Most-Favored Nation status. It enjoys Everything But Arms (EBA) and the Generalized System of Preferences (GSP) program preferences while trading with other countries. Besides, Cambodia provides one of Asia’s lowest labour costs and friendly regulations for the investment. These and other attractive benefits make more and more foreign investors enter Cambodia market.

The same with the branch, a RO in Cambodia has no separate legal personality from its parent company. Liabilities incurred by a RO are liabilities of the parent company. The main difference between a limited company, a branch and a RO is that a RO is not allowed to carry out generating profit activities (regular sale, purchase of goods, services, manufacturing, construction). It is primarily concerned with sourcing local goods and services and garnering local information for the parent company. It also serves as a vehicle for promoting and marketing the parent company’s products and services in Cambodia. A RO is thus best suited in assisting foreign investors wishing to explore the marketplace and business opportunities of Cambodia.

Since a RO cannot conduct any business, it shall not receive any incentive as qualified investment project (“QIP”) to be approved by the Council for the Development of Cambodia. Meanwhile, a RO can be registered with tax department as medium taxpayer and pay patent tax of USD300 per year.

Basically, for the purpose of registering a RO in Phnom Penh, Cambodia, you will need to provide the registration certificate, Articles of Association, directors’ passport copies with the address of the parent company and the passport copies and the address of the authorized officer of a RO as well as the address of the registered office with office rental agreement, the principle business activity. The required documents and materials are detailed in Section 4 of this guide.
