Cambodia Tax System Overview
Cambodia's tax system is administered by the General Department of Taxation (GDT) under the Ministry of Economy and Finance. The system is designed around territorial principles, meaning only income sourced within Cambodia is subject to taxation.
Territorial Taxation
Cambodia taxes only income earned within its borders. Income from foreign sources — such as overseas investments, foreign rental properties, or work performed abroad — remains outside the scope of Cambodian taxation.
Currency & Payments
Tax returns and payments are filed in Khmer Riel (KHR). The official exchange rate published by the National Bank of Cambodia is used to convert USD-denominated income. Most businesses operate in USD day-to-day but must report in KHR.
Tax Authority
The General Department of Taxation (GDT) manages all tax collection, audits, and compliance. Taxpayers register for a Tax Identification Number (TIN) and file through the GDT's online portal or in person at provincial offices.
Self-Assessment System
Cambodia operates a self-assessment regime: taxpayers calculate their own liability and file returns. The GDT conducts audits and may reassess returns within 3 years of filing (6 years in cases of fraud).
Personal Income Tax (PIT)
Personal Income Tax (PIT) applies to all residents earning Cambodia-sourced income. Residents are taxed on a progressive scale from 0% to 20%. Non-residents pay a flat 20% withholding on all Cambodia-sourced income.
2026 PIT Brackets (Monthly Income)
| Monthly Income (KHR) | Tax Rate |
|---|---|
| 0 – 1,500,000 KHR | 0% |
| 1,500,001 – 2,000,000 KHR | 5% |
| 2,000,001 – 8,500,000 KHR | 10% |
| 8,500,001 – 12,500,000 KHR | 15% |
| Over 12,500,000 KHR | 20% |
Fringe Benefits Tax
Benefits in kind (housing, vehicles, education allowances) provided by employers are taxed at 20% of their market value. This is paid by the employer on top of the employee's salary tax.
Deductions & Allowances
Residents can deduct donations to approved charitable organizations (up to 5% of taxable income). Dependents (spouse and children) each provide a fixed monthly deduction of 150,000 KHR from taxable salary.
Filing & Payment
Employers withhold PIT monthly from salaries and remit it to the GDT by the 20th of the following month. Self-employed individuals and freelancers must register and file monthly returns on the same schedule.
Corporate Tax (CIT)
All companies operating in Cambodia pay Corporate Income Tax (CIT) on their Cambodia-sourced profits. The standard rate is 20%, with variations for specific sectors. Companies are classified into three taxpayer categories based on annual turnover.
Small Taxpayer
< 250M KHR
Simplified regime with estimated tax. Ideal for freelancers and micro-businesses with annual revenue under ~$62,000.
Medium Taxpayer
250M–700M KHR
Standard accounting required. Covers most SMEs with annual revenue between ~$62,000 and ~$175,000.
Large Taxpayer
> 700M KHR
Full audit-ready accounting required. Applies to businesses with annual revenue exceeding ~$175,000.
Standard CIT Rate
The standard corporate tax rate is 20% on taxable profit. Oil, gas, and mineral exploitation companies pay 30%. QIP (Qualified Investment Project) companies may benefit from tax holidays of 3 to 9 years.
Patent Tax (Patente)
An annual business license tax ranging from 300,000 KHR to 3,000,000 KHR depending on taxpayer category. Due each year by March 31.
Prepayment of Tax (PoT)
Companies pay 1% of quarterly turnover (including VAT-exclusive revenue) as a prepayment toward their annual CIT liability. This is credited against the final CIT bill.
Withholding Tax
Payments to non-residents are subject to 14% withholding tax on services, royalties, and interest. Payments to residents for services are withheld at 15%. Rental payments are withheld at 10%.
Capital Gains Tax (CGT)
Cambodia introduced its Capital Gains Tax (CGT) framework in stages. The tax applies at a flat rate of 20% on gains from the sale of capital assets, including real estate, shares, and intellectual property.
Phase 1: Immovable Property
Effective since 2024
CGT on sales of land and buildings. Applies to properties held for investment or business purposes. Primary residences may qualify for exemption under specific conditions.
Phase 2: Financial Assets
Effective since 2025
CGT extended to cover gains from shares, bonds, and other financial instruments. This phase aligns with Cambodia's growing securities market.
Calculation Methods
Method A: Actual Gain
Sale price minus documented acquisition cost and improvement expenses. Requires receipts and proof of original purchase price. Recommended when records are complete.
Method B: Deemed Gain
Sale price minus a deemed cost based on official land valuation tables. Used when acquisition documents are unavailable or incomplete. Often results in a higher taxable gain.
Key Exemptions
Value Added Tax (VAT)
Cambodia's Value Added Tax (VAT) applies to the supply of goods and services within the country, as well as to imports. Understanding VAT obligations is essential for any business operating in Cambodia.
Standard Rate
The standard VAT rate is 10%, applied to most goods and services. Exports are zero-rated (0%), allowing exporters to reclaim input VAT credits.
Registration Threshold
Businesses with annual turnover exceeding 125 million KHR (~$31,000) must register for VAT. Voluntary registration is available for smaller businesses wanting to reclaim input VAT.
Invoice Requirements
VAT-registered businesses must issue tax invoices showing the VAT amount separately. Invoices must include the seller's TIN, buyer details, and a sequential invoice number.
Record Keeping
Businesses must maintain purchase and sales records for a minimum of 10 years. Monthly VAT returns are due by the 20th of the following month.
Exempt Supplies
Certain supplies are VAT-exempt: public postal services, medical and dental services, public transportation, insurance services, primary financial services, and imports of certain agricultural inputs.
French Tax Obligations
French nationals living in Cambodia must carefully manage their tax obligations in both countries. France and Cambodia have yet to sign a bilateral tax treaty, making proactive tax planning essential to maintain full compliance.
Important: France-Cambodia Tax Treaty Status
France and Cambodia currently have separate tax systems with independent obligations. French expats in Cambodia should work with a cross-border tax advisor to ensure proper compliance in both jurisdictions and optimize their overall tax position.
French Income Tax Brackets (2026)
| Annual Taxable Income | Tax Rate |
|---|---|
| 0 – 11,294 EUR | 0% |
| 11,295 – 28,797 EUR | 11% |
| 28,798 – 82,341 EUR | 30% |
| 82,342 – 177,106 EUR | 41% |
| Over 177,106 EUR | 45% |
CSG/CRDS Contributions
French tax residents pay CSG (9.2%) and CRDS (0.5%) on most income. Non-residents are generally exempt from these social contributions on foreign-source income, but French-source investment income may still be subject to the 7.5% solidarity levy.
French Pension Income
French state pensions (retraite) paid to non-residents are taxed in France at a minimum rate of 20% (or 14.4% for income under 27,478 EUR). Private pension schemes may have different rules depending on the plan type.
Foreign Account Declarations
French nationals must declare all foreign bank accounts, investment accounts, and cryptocurrency accounts on Form 3916/3916-bis annually. Penalties for undeclared accounts start at 1,500 EUR per account per year.
Non-Resident Status
To qualify as a French non-resident for tax purposes, you must transfer your principal home, professional activity, and center of economic interests outside France. Simply living abroad is sometimes deemed insufficient if your family or assets remain in France.
Fiscal Residency Rules
Determining your fiscal residency is the foundation of your tax planning. Cambodia uses several criteria, and meeting any one of them can establish you as a tax resident.
182-Day Rule
Spending 182 days or more in Cambodia during a calendar year establishes tax residency. Days of arrival and departure both count. Short trips outside Cambodia still count toward the total if you maintain a habitual abode in the country.
Principal Activity
If your primary professional or business activity is conducted in Cambodia, you are considered a tax resident regardless of the number of days spent in the country.
Center of Economic Interests
If your primary source of income or the majority of your assets are located in Cambodia, this establishes fiscal residency even if you spend fewer than 182 days in the country.
Family & Habitual Abode
Maintaining a permanent home or having your immediate family (spouse, dependent children) residing in Cambodia is an additional factor that can establish tax residency.
Practical Tax Examples
These three profiles illustrate how Cambodia's tax system applies in practice. All figures are approximate and based on 2026 rates. Consult a qualified tax advisor for your specific situation.
French Retiree in Siem Reap
Age 65 · French state pension of 24,000 EUR/year · Renting an apartment in Siem Reap · Full-year resident
Cambodia: The pension is sourced from France, meaning it falls outside the scope of Cambodian taxation under the territorial system. Cambodian tax liability: $0.
France: As a non-resident, the pension is taxed in France at the minimum non-resident rate of 14.4% (income under 27,478 EUR). Annual French tax: approximately 3,456 EUR.
Total estimated annual tax: ~3,456 EUR (France only)
Expat Entrepreneur with a Cambodian Company
Age 42 · Sole owner of a Cambodian LLC · Annual profit of $60,000 · Pays himself a salary of $2,500/month
Cambodia: Salary taxed under PIT brackets (approximately $220/month after deductions). Company pays 20% CIT on remaining profit (~$6,000). Total Cambodian taxes: approximately $8,640/year.
France: As a confirmed non-resident with center of economic interests in Cambodia, French-source income obligations are limited to any remaining French investments or property. Estimated French tax: variable.
Total estimated annual tax: ~$8,640 (Cambodia) + French obligations on French-source income
Digital Nomad (Non-Resident)
Age 31 · Freelance developer · Clients in Europe · Spends 4 months/year in Cambodia · Income: $5,000/month
Cambodia: Spending fewer than 182 days in Cambodia and earning income from foreign clients means the income is outside the scope of Cambodian taxation. Cambodian tax liability: $0.
France: If still considered a French tax resident (family or assets in France), worldwide income is taxable in France. If confirmed non-resident, only French-source income is taxed.
Total estimated annual tax: depends entirely on French residency status — proper planning is essential
Tax Calendar & Deadlines
Missing a tax deadline in Cambodia can trigger penalties of 10% to 40% of the tax due, plus 2% monthly interest. Here are the key dates every expat and business owner should track.
| When | Obligation |
|---|---|
| 20th of each month | PIT withholding on salaries — file and pay to GDT |
| 20th of each month | Monthly VAT return and payment |
| 20th of each month | Withholding tax on payments to non-residents and service providers |

Conclusion & Key Takeaways
Cambodia's territorial tax system, combined with progressive PIT rates capped at 20% and a flat 20% CIT rate, creates a genuinely favorable environment for expats and entrepreneurs. The key to maximizing these advantages is understanding your fiscal residency status in both Cambodia and your home country.
For French nationals, the absence of a bilateral tax treaty makes professional tax advice especially valuable. With proper planning, it is entirely possible to remain fully compliant in both jurisdictions while benefiting from Cambodia's competitive rates. Start by establishing your residency status clearly, then build your tax strategy from there.
