A Practical Guide to Withholding Tax, VAT, Profit Tax, Tax Registration, and QIP Exemptions

As Cambodia continues its transformation into one of Southeast Asia’s most attractive emerging markets, foreign investors are pouring capital into real estate, manufacturing, agriculture, and renewable energy. But before reaping the rewards of the Kingdom’s rapid economic growth, understanding the Cambodian tax system is essential.

In this 2025 guide, we break down everything foreign investors need to know—from withholding tax and VAT to profit tax, tax registration, and QIP (Qualified Investment Project) exemptions. Plus, we’ll show you how Adaeng Development can help you structure, register, and optimize your business from day one.

📌 Why Foreign Investors Must Understand Cambodia’s Tax Code

Cambodia’s tax environment is dynamic, rules-based, and increasingly digitized under reforms led by the General Department of Taxation (GDT). Proper compliance ensures:

• Long-term stability
• Access to incentives
• Avoidance of penalties or audits
• Eligibility for foreign remittance and profit repatriation

🧾 Overview of Cambodia’s Tax System

Cambodia operates a self-assessment tax regime under the Law on Taxation (updated in 2023), governed by the GDT under the Ministry of Economy and Finance. Taxes are categorized as:

💸 1. Withholding Tax (WHT)

Withholding tax is applied when Cambodian-registered entities pay for services from either resident or non-resident taxpayers.

Resident Withholding Rates:

Non-Resident Withholding Rates:

Flat 14% on payments to foreign companies or individuals with no tax registration in Cambodia.

Note: Failure to withhold or submit tax on time results in penalties and interest charges.

🏷️ 2. Value Added Tax (VAT)

Cambodia’s standard VAT rate is 10%, applied to:

• Domestic sales of goods and services
• Importation of goods

Who Must Register?

• Entities with annual turnover > KHR 250 million (~$60,000 USD).
• Voluntary registration is possible for smaller firms engaged in exports or B2B services.

VAT Input vs. Output

• Input VAT: Tax paid on business purchases—claimable as credits
• Output VAT: Tax charged to customers—must be remitted to GDT

➡️ Tip: If you’re an exporter or developer dealing with international supply chains, VAT compliance is vital to avoid cash flow bottlenecks. Adaeng Development helps set up monthly reporting systems and reverse VAT claims (www.adaeng.co/services).

📈 3. Profit Tax (Corporate Income Tax)

Corporate profit tax applies to all resident and non-resident businesses earning income in Cambodia. Rates depend on company size:

Deductions & Allowances

• Depreciation on fixed assets
• Business-related expenses
• Interest expenses (if compliant with thin capitalization rules)

Minimum Tax

Applies at 1% of turnover, even if the company is loss-making—unless exempted via QIP registration.
