What is Cambodia’s Capital Gains Tax?

Cambodia’s capital gains tax, established under Prakas No. 496 MEF.PRK (effective July 18, 2025), represents a significant shift in the country’s tax framework. The CGT applies a flat 20% rate to profits from the sale or transfer of capital assets, aligning Cambodia with regional ASEAN peers while creating new considerations for foreign investors.

CGT Implementation Timeline 2025-2026

Phase 1: September 1, 2025

The following assets are now subject to CGT:

• Securities and shares in Cambodian companies
• Lease agreements and lease rights
• Intellectual property (patents, trademarks, copyrights)
• Goodwill and business assets
• Foreign currency transactions

Phase 2: January 1, 2026

• Real estate (land and buildings)
• Immovable property transactions

How Cambodia’s Capital Gains Tax Works

Tax Calculation Method

The CGT applies to the net capital gain, calculated as:

Selling Price - Allowable Expenses = Taxable Capital Gain
Taxable Capital Gain × 20% = CGT Liability

Real Estate Special Provisions (2026)

For immovable property, taxpayers can choose between:

1. Standard Deduction: 80% of taxable income
2. Actual Cost Method: Documented expenses with supporting evidence

Realization Events

A capital gain is realized when:

• Legal ownership changes hands through sale
• Court judgment transfers ownership
• Official registration occurs
• For shares: seller loses control or receives full payment

CGT Compliance Requirements 2025

Declaration and Payment Deadlines

• Timeframe: 3 months from realization event
• Payment Requirement: Tax must be paid before transfer completion
• Documentation: Robust record-keeping essential for expense deductions

Withholding Responsibilities

• Cambodian Enterprises: Must withhold CGT on share transfers
• Licensed Settlement Agents: Responsible for securities and financial transactions
• Non-Compliance Risk: Transfer legally incomplete until tax paid

Exemptions and Relief Measures

Individual Residence Exemption

Resident individuals selling their principal residence are exempt if:

• Property held for more than 5 years
• Supported with proper documentation
• One-time exemption per individual

Double Taxation Agreement Relief

Foreign investors may benefit from reduced CGT rates through:

• Formal DTA application with supporting evidence
• Potential rate reduction (example: 10% vs. 20%)
• Material tax savings on large transactions

New Share Issues

Capital increases through new share issuances are exempt from CGT.

Regional Comparison: Cambodia vs. ASEAN Peers

Cambodia’s 20% flat rate is relatively high for securities compared to regional peers, making tax planning crucial for competitive returns.

Impact on Foreign Investment Strategies

Investment Returns Calculation

Foreign investors must now factor CGT into:

• Expected returns: Reduce projected gains by 20%
• Exit planning: Time transactions strategically
• Structure optimization: Consider DTA benefits
• Documentation: Maintain detailed expense records

Real Estate Investment Window

The period between September 2025 and December 2025 offers a final opportunity for real estate transactions without CGT. Foreign investors considering property investments should evaluate timing carefully.

Practical Examples: CGT in Action

Corporate Share Sale Example

A foreign corporation sells shares in a Cambodian company on September 15, 2025:

• Capital Gain: USD 5 million
• CGT at 20%: USD 1 million
• Net Proceeds: USD 4 million
• With DTA (10%): USD 500,000 tax, USD 4.5 million net

Real Estate Transaction Example

Foreign investor selling property in 2026:

• Capital Gain: USD 1.2 million
• Option 1 (80% deduction): Tax on USD 240,000 = USD 48,000
• Option 2 (actual costs): Varies based on documentation
• Decision impact: Potentially hundreds of thousands in tax savings

Strategic Recommendations for Foreign Investors
