Quick Answer — Cambodia Expat Tax 2026
Expats in Cambodia pay Tax on Salary (ToS) on Cambodia-sourced income at progressive rates of 0% to 20%. Cambodia uses a territorial tax system — if your income comes from outside Cambodia, it is not taxed here. You become a tax resident after spending 182 or more days in Cambodia in a calendar year. Employed expats have tax withheld monthly by their employer. Freelancers and self-employed individuals must register with the General Department of Taxation (GDT) and file and pay taxes quarterly. Cambodia’s top marginal rate of 20% applies only to monthly income above $8,500. For most expats earning a typical local salary, the effective rate is significantly lower — often 8–12%. Cambodia does not levy a separate capital gains tax on most assets, and foreign-sourced passive income (pensions, overseas dividends, rental income abroad) is not subject to Cambodian tax.

Are You a Tax Resident of Cambodia?
Before anything else, you need to establish whether Cambodia considers you a tax resident. This determines which of your income streams are subject to Cambodian tax.
The 182-day rule: Under the Law on Taxation (LoT), you are a Cambodian tax resident if you are physically present in Cambodia for 182 days or more in a calendar year (January 1 – December 31). Days do not need to be consecutive. If you are in Cambodia for 182 days spread across the year, you are a tax resident for that full year.
✓ Tax Resident (182+ days)
⚠ Non-Resident (under 182 days)
Practical note: Most expats living and working full-time in Cambodia are tax residents. If you are on an E-visa, business visa, or retirement visa and spending the majority of the year here, the 182-day threshold is almost certainly crossed. Track your travel carefully if you regularly leave Cambodia.
Cambodia’s Territorial Tax System — The Biggest Advantage for Expats
This is the single most important thing to understand about Cambodia’s tax system, and it is extremely favourable for most expats. Cambodia taxes only income sourced within Cambodia. Foreign-sourced income is outside the scope of Cambodian tax — full stop.
This means that regardless of how long you live in Cambodia, the following are not subject to Cambodian income tax:
Why this matters: A retiree receiving a $3,000/month UK pension or Australian superannuation payout owes zero Cambodian income tax on that income. A digital nomad paid by US or European clients in USD into a foreign account also owes no Cambodian tax — as long as their income is not sourced from a Cambodian entity. Cambodia is a genuinely competitive jurisdiction for expats with foreign income streams.
Important caveat: While Cambodia may not tax your foreign income, your home country may still tax you on worldwide income. This is your home country’s law, not Cambodia’s. The UK, Australia, USA, Germany, and many others tax citizens or residents on worldwide income regardless of where they live. Always consult a tax adviser in your home country before assuming you have no home-country obligations.
Tax on Salary (ToS) — Cambodia’s 2026 Income Tax Rate Table
Cambodia’s income tax for individuals is called Tax on Salary (ToS). It applies progressive rates to monthly income brackets. These rates apply to tax residents. The table below uses USD, as most expat salaries and many formal employment contracts in Cambodia are denominated in US dollars.

Employed Expats — How Payroll Tax Works in Cambodia
If you work for a registered Cambodian employer — whether a local company, an international NGO, or a foreign company with a Cambodian entity — your employer is legally required to calculate and withhold Tax on Salary from your monthly pay and remit it to the GDT by the 20th of the following month.
In practical terms, most employed expats in Cambodia never have to interact directly with the tax authority. Your payroll department handles everything. Your payslip should show your gross salary, the ToS amount withheld, and your net pay. If you are a senior employee or have additional income (rental income from a Cambodian property, directorship fees), you may also have individual filing obligations.
Taxable components of your package: The GDT takes a broad view of “salary.” In addition to your base salary, the following are generally included in taxable income:
NSSF note: Cambodia’s National Social Security Fund (NSSF) requires employee contributions of 2% of gross salary (with a cap) toward healthcare and pension schemes. Employers contribute an additional 2.6–3%. This is separate from income tax. See our dedicated guide on NSSF contributions for full details.
Freelancers, Self-Employed Expats & Business Owners
This section matters most to digital nomads, consultants, freelancers, and expats who operate their own businesses in Cambodia. The rules are more complex than for employees, and non-compliance is the most common tax problem that expats in Cambodia face.
Cambodia-Sourced vs. Foreign-Sourced Freelance Income
The territorial system applies here too. If you are a freelance designer, developer, writer, or consultant and all of your clients are foreign entities paying you into a foreign account, your income is not Cambodia-sourced. You owe no Cambodian income tax on it — regardless of whether you live in Phnom Penh. This is why Cambodia is popular with digital nomads.
If, however, you are providing services to Cambodian companies, NGOs, or individuals, that income is Cambodia-sourced and is subject to tax.
Business Registration & Tax Regimes
If you operate a business in Cambodia — even a sole proprietorship — you are required to register with the GDT and comply with the relevant tax regime. Cambodia has three business tax regimes:
🟢
Small Taxpayer
Annual turnover under ~$62,500. Simplified quarterly filing. Lower compliance burden.
🟡
Medium Taxpayer
Annual turnover $62,500–$500,000. Monthly filing obligations. Full accounting required.
🔴
Large Taxpayer
Annual turnover above $500,000. Large Taxpayer Department (LTD). Full audit-ready accounting required.
Profit Tax rate for businesses: The standard corporate profit tax rate in Cambodia is 20%. Qualified investment projects (QIPs) may receive tax holidays of 3–9 years.
Important: Many freelancers and small business owners in Cambodia operate informally without GDT registration. This is illegal and carries risk of back taxes, penalties, and fines. If you are earning Cambodia-sourced income from services rendered in Cambodia, register with the GDT. A registered local accountant can set this up for $50–200/month in fees — far less than the cost of non-compliance.
What Cambodia Doesn’t Tax — Key Reliefs for Expats
One of Cambodia’s most appealing characteristics for expats is what the tax system does not cover. Understanding these exemptions is as important as understanding what is taxed.

Double Tax Treaties — Does Cambodia Have One With Your Country?
A Double Tax Agreement (DTA) is a treaty between two countries that prevents the same income from being taxed twice — once in each country. Cambodia has a relatively small number of DTAs compared to countries like Singapore or the UK, but the list is growing.
Countries with a DTA with Cambodia (verified as of 2026):
If your country has no DTA with Cambodia: You may face double taxation — paying tax in both Cambodia and your home country on the same income. Most Western countries (UK, Australia, USA) have Foreign Tax Credit systems that allow you to offset taxes paid abroad against your home-country liability. This is complex — consult both a Cambodian tax adviser and a home-country tax professional.
How to File & Pay Your Taxes in Cambodia
Cambodia’s GDT has progressively modernised its systems. Most tax filing and payment can now be done electronically via the GDT online portal (etax.tax.gov.kh), though working with a local accountant is still the most practical approach for most expats.
Payment Methods
GDT tax payments in Cambodia can be made via:
🏦
Bank Transfer
Direct transfer to GDT’s designated bank accounts at ABA, ACLEDA, and Canadia Bank
📱
GDT eTax Portal
Online filing and payment at etax.tax.gov.kh (requires GDT registration)
🏢
GDT Tax Office
In-person payment at GDT district offices. Phnom Penh main office: Khan Daun Penh
Banking tip: Using ABA Bank or ACLEDA Bank for your business banking makes GDT tax transfers straightforward — both banks are integrated with the GDT payment system and allow same-day tax remittances through their mobile apps. See MoneyKH’s Best Banks in Cambodia 2026 comparison for full details.
7 Common Tax Mistakes Expats Make in Cambodia
These are the most frequent errors that lead to GDT penalties, back tax assessments, and in some cases, legal complications. Each is avoidable with basic awareness.
① Assuming Cambodia has “no taxes”
Cambodia is not a zero-tax jurisdiction. It taxes Cambodia-sourced income. The confusion arises because foreign income is not taxed — which is excellent — but many expats conflate this into thinking nothing is taxed.
② Not registering a business with the GDT
Operating informally is extremely common, especially among small expat business owners. The GDT has significantly increased enforcement. A business registration and monthly accounting costs a fraction of a single penalty.
③ Misclassifying employees as contractors
Paying someone a monthly fixed fee without withholding ToS because they’re called a “consultant” is a common risk. The GDT looks at the economic reality of the arrangement, not just the label.
④ Forgetting that the tax year is January–December
Expats used to UK tax years (April–April) or Australian tax years (July–June) sometimes miscalculate Cambodia’s year. It runs January 1 to December 31. Annual returns are due March 31.
⑤ Ignoring home-country obligations
Cambodia’s territorial system exempts foreign income from Cambodian tax. But your home country — especially the USA (which taxes citizens worldwide), UK, and Australia — may still require you to file and pay tax. Living in Cambodia does not eliminate home-country obligations.
⑥ Not tracking days for the 182-day rule
If you travel frequently and want to remain a non-resident for a specific tax year (to benefit from certain treaty provisions), you must track your days meticulously. Assume Cambodia counts any partial day as a day present.
⑦ Assuming the 2022 property capital gains tax doesn’t apply
Many expats who bought property before 2022 are unaware that capital gains from selling Cambodian real estate are now taxed at 20%. If you are selling a Cambodian property, factor this in and seek professional advice before signing any agreements.
Frequently Asked Questions & Getting Professional Help
Q: I work remotely for a foreign company and live in Phnom Penh. Do I owe Cambodian tax?
A: Under Cambodia’s territorial system, your foreign employer’s salary is not Cambodia-sourced income and is not subject to Cambodian Tax on Salary. You are however legally resident in Cambodia and should be aware that if you provide any services to Cambodian clients or establish a local business entity, those activities would be taxable. Consult a local tax adviser to review your specific arrangement.
Q: I receive a UK state pension. Do I pay tax on it in Cambodia?
A: No. A UK state pension paid by the UK government to a Cambodian resident is not Cambodia-sourced income and is not taxed in Cambodia. You may still have UK filing obligations. The UK does have a tax treaty arrangement with Cambodia but the specifics of pension taxation can be nuanced — confirm with a UK accountant.
Q: Are there any tax deductions or allowances I can claim as an expat?
A: The Cambodian tax system has limited personal deductions compared to Western systems. There is no mortgage interest deduction, no pension contribution relief, and no standard personal allowance beyond the 0% bracket on the first $125/month. Business expenses are deductible for registered businesses. A registered accountant can identify any available deductions within your specific circumstances.
Q: What happens if I don’t pay tax in Cambodia?
A: The GDT can impose penalties of 10–25% of the unpaid tax amount, plus interest at 2% per month on outstanding amounts. In serious cases of evasion, criminal penalties including fines and imprisonment are possible. The GDT has been progressively increasing enforcement, particularly targeting informal businesses in Phnom Penh.
Q: How much does a Cambodian tax accountant cost?
A: For a simple employed expat, an accountant may not be necessary at all — your employer handles everything. For a freelancer or small business owner, monthly accounting and compliance services range from $80–$250/month depending on complexity and the firm. Annual tax filing assistance typically costs $150–$500 separately. International-grade Phnom Penh accounting firms (KPMG, Deloitte, PricewaterhouseCoopers, and Grant Thornton all have Cambodia offices) charge significantly more but offer full international compliance coverage.

MoneyKH Verdict
Cambodia Is One of the Most Tax-Efficient Places in Southeast Asia for Expats — If You Understand the System
The territorial tax system is genuinely excellent. No tax on foreign pensions, foreign salary, or foreign investment income — regardless of how long you live here. For retirees, digital nomads, and expats with offshore income streams, Cambodia competes with Thailand and Malaysia as among the most attractive tax environments in ASEAN.
For employed expats working for Cambodian companies, the progressive rates of 0–20% are reasonable — most expats on typical Phnom Penh salaries pay an effective rate of 8–12%. Compliance is straightforward when your employer handles withholding correctly.
The risks are for the uninformed: assuming Cambodia is “tax-free”, operating businesses informally, ignoring home-country obligations, or not accounting for the 2022 property capital gains tax. These are solvable with a $100–200/month relationship with a local accountant.
