Cambodia Expat Tax Guide 2026: Do You Pay Income Tax?

Your employer withholds Salary Tax (Tax on Salary / ToS) at source each month and remits it to the GDT by the 20th of the following month. You receive your net salary. You are still responsible for ensuring your employer is filing correctly — if they fail to remit, the GDT can pursue you personally.

If you operate as a self-employed individual rather than through a company, you are required to register with the GDT, self-assess your income, and pay salary tax on your drawings. You must file a monthly salary tax return by the 20th. Practically, many freelancers in Cambodia do not register — but the legal risk increases as income grows and if you have a fixed place of business.

Your company pays 20% Corporate Income Tax (CIT) on net profits. When you distribute profits to yourself as dividends, a further 14% withholding tax applies on dividends paid to non-residents. On Cambodia-source salary drawn from your own company, standard progressive salary tax applies. Structuring your salary vs dividend mix affects your effective tax rate.

Cambodia's General Department of Taxation focuses enforcement on Cambodia-source income. Foreign pensions, foreign dividends, and foreign investment returns paid directly to a foreign account and not remitted to a Cambodian entity are generally not assessed or audited. There is no capital gains tax on foreign assets. Retirees on CM2H visas living on overseas pension income are effectively not taxed in Cambodia in practice.

If you are physically present in Cambodia for 182+ days/year but earn exclusively from clients outside Cambodia and are not employed by a Cambodian entity, you technically fall into a grey area. Cambodia's GDT enforcement focuses on registered entities. However, operating without any local registration while building a business presence here carries long-term risk. Many digital nomads stay under the enforcement threshold — but this is not guaranteed to remain the case as Cambodia tightens compliance.

Do I pay tax on money I earn from clients abroad while living in Cambodia?

This is the most common question from digital nomads. If you are not employed by a Cambodian-registered entity and your clients pay directly to a foreign account, Cambodia's GDT does not currently have the enforcement infrastructure to assess or collect tax on that income. In theory, as a tax resident (182+ days), Cambodia could assert a right to tax worldwide income — but in practice, the GDT focuses on Cambodia-registered businesses and their employees. The risk grows if you set up a physical office, hire local staff, or register any Cambodian business presence. Consult a tax advisor if your income is substantial.

What if my home country also taxes me — do I pay double?

It depends on whether your home country has a Double Taxation Agreement (DTA) with Cambodia and your personal tax residency situation. Cambodia has 14 DTAs (China, Singapore, Thailand, Vietnam, Brunei, Indonesia, Malaysia, South Korea, Hong Kong, UAE, Macau, Czech Republic, Laos, Qatar). If your country is on this list, the DTA will typically provide a tax credit or exemption mechanism. If your country is NOT on the list (e.g., UK, USA, Australia, Germany), you may face double taxation in theory — though for most expats living and working exclusively in Cambodia, their home country would consider them non-resident for tax purposes. US citizens are a notable exception: the US taxes citizens on worldwide income regardless of residency, though the Foreign Earned Income Exclusion (up to USD 126,500 for 2024) reduces this significantly.

Is there a tax on my foreign pension income?

Foreign pension income paid to a foreign account and not channeled through a Cambodian employer or entity is not assessed by the GDT in practice. Cambodia has no specific pension taxation regime. Retirees on CM2H visas or retirement visas who live on overseas pensions are effectively not taxed in Cambodia on that pension. However, if you receive pension payments into a Cambodian bank account and then declare it as income through a Cambodian business structure, different rules could apply. The safest arrangement is to keep your foreign pension separate from any Cambodian business income.

Do I need to file a tax return as an individual expat in Cambodia?

If you are employed by a registered Cambodian company, your employer files the monthly Salary Tax return on your behalf and withholds the correct amount — you do not need to file a personal return separately. If you are self-employed, running your own business, or have Cambodia-source income outside of employment, you must register with the GDT and file returns accordingly. Most expats employed by Cambodian companies do not need to personally file anything — their employer handles it. However, you should verify your employer is actually filing correctly; non-compliance by the employer does not eliminate your liability.

What is the penalty for not declaring income in Cambodia?

For late filing, the penalty is 10% of any tax due plus 1.5% per month in interest. For intentional tax evasion or fraudulent returns, the surcharge rises to 25–40% of unpaid tax plus potential criminal prosecution. The GDT can assess back taxes for the previous 10 years in cases of fraud. For undeclared income that is discovered on audit (which is increasingly common), the GDT typically assesses all back taxes, applies the 10% penalty, and adds monthly interest. For foreign-owned companies and their expatriate employees, the GDT has been conducting targeted audits since 2022. The practical message: if you have significant Cambodia-source income, register and comply — the cost of a good accountant (USD 200–500/month) is far less than a back-tax assessment.
