Cambodia Tax Residency 2026: Rules for Expats, Remote Workers & Digital Nomads
Whether you spend six months a year in Phnom Penh, work remotely for a foreign employer, or have recently set up a Cambodian company — understanding Cambodia's tax residency rules is essential to staying compliant and avoiding costly surprises. The 182-day threshold, salary tax brackets, DTA treaties, and digital nomad grey areas all covered here.
What Is Tax Residency in Cambodia?
Under Cambodia's Law on Taxation (LoT) and subsequent prakas (ministerial regulations), a person becomes a Cambodian tax resident by being physically present in Cambodia for 182 or more days in a calendar year (January 1 to December 31). There is no other basis for individual tax residency — nationality, domicile, and permanent home are irrelevant. The test is purely physical presence.
Days are counted in aggregate — they do not need to be consecutive. A trip to Bangkok for a week, returning to Phnom Penh, then a month in Singapore, then back in Cambodia all counts cumulatively. Immigration entry and exit records at Cambodian borders are the official source of the count, though the GDT does not routinely audit individual travellers' passport stamps.
The significance of crossing the 182-day threshold is that you move from a non-resident tax status (flat 20% withholding tax on Cambodian-source income only) to a resident tax status (graduated salary tax schedule, in theory on worldwide income). In practice, as explained below, enforcement focuses on Cambodian-source income regardless of residency status.
Resident vs. Non-Resident: Tax Treatment Comparison
| Factor | Non-Resident (<182 days) | Resident (≥182 days) |
|---|---|---|
| Income scope | Cambodian-source income only | Worldwide income (in theory) |
| Salary tax rate | Flat 20% withholding | Graduated 0%–20% schedule |
| Tax filing obligation | Withheld by payer | Employer files monthly returns |
| DTA treaty access | May apply to source-based income | Broader DTA access as resident |
| NSSF obligation | Only if locally employed | Only if locally employed |
| Foreign income taxed? | No (source-based only) | Technically yes; rarely enforced |
Cambodia Salary Tax Brackets 2026
For tax residents, salary tax (equivalent to income tax on employment income) applies on a graduated scale. The brackets are set in Cambodian Riel (KHR), with approximate USD equivalents at the 2026 exchange rate of approximately KHR 4,080 per USD. These brackets apply to monthly income.
| Monthly Income Range | Tax Rate | Notes |
|---|---|---|
| Under KHR 1,300,000/month (≈ USD 318) | 0% | Tax-free threshold |
| KHR 1,300,001 – 2,000,000/month (≈ USD 319–490) | 5% | Low-income bracket |
| KHR 2,000,001 – 8,500,000/month (≈ USD 491–2,082) | 10% | Middle bracket |
| KHR 8,500,001 – 12,500,000/month (≈ USD 2,083–3,062) | 15% | Upper-middle bracket |
| Above KHR 12,500,000/month (above ≈ USD 3,062) | 20% | Top marginal rate |
Practical note on enforcement: Cambodia's GDT primarily enforces salary tax through employers — if you receive a Cambodian salary from a registered Cambodian company, your employer withholds and remits your salary tax monthly. Individual self-assessment by expats on non-Cambodian income is rare and enforcement is limited. However, the legal obligation exists for residents. Expats on higher international salaries working for registered companies should ensure their employer correctly applies the brackets.
The In-Practice Reality: What Cambodia Actually Taxes
Despite the theoretical worldwide income basis for residents, Cambodia's General Department of Taxation focuses enforcement on Cambodian-source income. This means:
Cambodia's Double Tax Agreements (DTAs)
Cambodia has negotiated Double Tax Agreements with approximately 20 countries, primarily its Asian trading partners. These agreements prevent the same income from being taxed twice — once in Cambodia and once in your home country. DTAs typically cover dividend income, interest income, royalty payments, and business profits, specifying which country has primary taxing rights and at what rates.
| Treaty Partner Country | Provisions Covered | Status |
|---|---|---|
| China | Dividend, interest, royalty, business profit | In force |
| Singapore | Dividend, interest, royalty, business profit | In force |
| Thailand | Dividend, interest, royalty, business profit | In force |
| Vietnam | Dividend, interest, royalty, business profit | In force |
| Indonesia | Dividend, interest, royalty, business profit | In force |
| South Korea | Dividend, interest, royalty, business profit | In force |
| Hong Kong | Dividend, interest, royalty, business profit | In force |
| Malaysia | Dividend, interest, royalty, business profit | In force |
| Brunei | Dividend, interest, royalty, business profit | In force |
| Other (~10 more) | Various — check GDT treaty list | In force |
Note: Notable countries without DTAs with Cambodia as of 2026 include the USA, UK, Australia, Canada, France, and Germany. Expats from these countries cannot rely on DTA relief and must manage double taxation through home-country mechanisms such as Foreign Tax Credits or Foreign Earned Income Exclusions.
Digital Nomads & Remote Workers: The Grey Area Explained
Cambodia is one of Southeast Asia's most popular destinations for digital nomads — low cost of living, fast internet in cities, and a relaxed visa regime. But the tax position for remote workers is genuinely unresolved.
The legal theory: If you are present in Cambodia for 182+ days and performing work here (even for a foreign employer with no Cambodian presence), the income from that work is technically Cambodian-source income under the LoT. A strict reading of the law means it is subject to Cambodian salary tax.
The practical reality: The GDT does not have a system or mechanism to track remote workers employed by foreign entities with no Cambodian registration. Most digital nomads working on E-class visas for foreign companies pay no Cambodian tax and face no enforcement. This has been the status quo for years.
Risk increases materially if you: (1) operate a registered Cambodian company or sole proprietorship; (2) invoice Cambodian clients or receive income into a Cambodian bank account from Cambodian sources; (3) have employees or staff in Cambodia; or (4) hold visible business premises (office, co-working space under your entity name). In any of these circumstances, engage a Cambodian tax advisor to structure your affairs properly.
NSSF: National Social Security Fund Obligations
The National Social Security Fund (NSSF) is Cambodia's social security system, covering health care and pensions for employees of registered Cambodian companies. Contributions are mandatory for all employees — including foreign nationals — working for registered Cambodian employers.
| Contribution Type | Employee Rate | Employer Rate | Notes |
|---|---|---|---|
| Occupational Risk (ORC) | 0% | 0.8% | Employer only; workplace injury scheme |
| Health Care (HCF) | 0% | 1.3% | Employer only; medical benefits |
| Pension Scheme (PF) | 4% | 4% | Phased rollout; applies to most employers now |
Home Country Tax Obligations: Don't Forget Them
Becoming a Cambodian tax resident does not automatically eliminate your tax obligations in your home country. This is one of the most common misconceptions among expats relocating to Cambodia.
United States
US citizens and permanent residents are taxed on worldwide income regardless of where they live. Moving to Cambodia does not remove this obligation. US expats must file annual US tax returns and may use the Foreign Earned Income Exclusion (FEIE, up to ~USD 126,500 in 2026) or Foreign Tax Credit to reduce double taxation. FBAR and FATCA reporting requirements also apply if foreign account balances exceed thresholds.
United Kingdom
UK tax residency is determined by the Statutory Residence Test (SRT), which is complex and goes beyond days. UK residents remain liable for UK income tax on worldwide income. If you genuinely become non-UK resident by spending sufficient days abroad and severing UK ties, your UK liability may reduce — but this requires careful planning under the SRT rules.
Australia
Australian tax residency is also a complex test involving domicile, permanent place of abode, and the 183-day rule. Australian residents are taxed on worldwide income. Australians working abroad often remain Australian tax residents unless they have genuinely established a permanent home abroad and intend to remain outside Australia indefinitely.
Canada
Canadian tax residency is based on residential ties (home, spouse, dependants, social connections). Simply being in Cambodia for 182+ days does not sever Canadian residency. Canadians should seek specific advice on breaking Canadian tax residency before assuming they have done so.
Cambodia Tax Compliance Steps for Expats
Frequently Asked Questions
Does the 182-day rule mean I owe Cambodian tax on my worldwide income?
In theory, a Cambodian tax resident (182+ days in the calendar year) is subject to salary tax on worldwide income. However, in practice the General Department of Taxation (GDT) primarily enforces tax on Cambodian-source income — meaning your Cambodian salary, business income from Cambodia, and rental income from Cambodian properties. Foreign-source income (such as dividends from overseas investments) is rarely pursued unless you bring it onshore or declare it. That said, the legal obligation exists, and Cambodia's tax enforcement is gradually strengthening. If you have significant foreign income, consult a tax lawyer rather than assuming non-enforcement.
I work remotely for a foreign company from Cambodia. Do I owe tax here?
This is the most common grey area. If you are physically present in Cambodia for 182+ days working remotely for a foreign employer that has no Cambodian presence, the income is technically Cambodian-source (work performed in Cambodia). The GDT does not currently aggressively pursue remote workers employed by purely foreign companies with no Cambodia nexus. Risk increases significantly if you: (1) invoice Cambodian clients, (2) operate through a Cambodian company structure, or (3) have visible indicators of permanent establishment. The safest position is to seek a written tax opinion from a Cambodian tax lawyer and maintain documentation that your income comes from a non-Cambodian source.
Is there an official digital nomad visa in Cambodia?
No — as of 2026 Cambodia does not have a formally designated digital nomad visa. Most remote workers and digital nomads enter on a standard E-class business visa (EB), which is renewable indefinitely via visa extension services. The business visa is technically intended for those conducting business in Cambodia, but in practice it is widely used by long-stay expats and remote workers. There is no official enforcement mechanism distinguishing remote workers from other EB visa holders. Cambodia has informally discussed a digital nomad program but has not legislated one.
How do I claim relief under a Double Tax Agreement (DTA) with Cambodia?
To claim DTA relief in Cambodia, you must: (1) obtain a Certificate of Tax Residence from your home country's tax authority (proving you are a resident of the treaty partner country); (2) submit a formal claim to the General Department of Taxation with the certificate and the relevant DTA provisions cited; (3) the GDT will review and issue a ruling on applicable treaty rates or exemptions. This process can take several weeks. It is strongly recommended to engage a Cambodian tax lawyer to navigate the GDT submission, as procedures are not always clearly published and require in-person coordination at the tax office.
Do I have to pay NSSF if I am self-employed or a freelancer in Cambodia?
The NSSF (National Social Security Fund) system in Cambodia is designed around employer-employee relationships. Self-employed individuals and freelancers without a registered Cambodian employer are not mandatorily enrolled in the NSSF system. However, if you establish a Cambodian company and pay yourself a salary through that company, NSSF contributions become mandatory for both the company (as employer) and yourself (as employee). Voluntary enrollment in the NSSF for self-employed individuals is possible but not widely practiced by expats.
I pay tax in my home country. Can Cambodia also tax me on the same income?
This depends on whether your home country has a Double Tax Agreement (DTA) with Cambodia. If a DTA exists (e.g., Singapore, Thailand, Vietnam, Korea, Hong Kong), it will determine which country has primary taxing rights on each type of income and may provide relief to avoid double taxation. If no DTA exists (e.g., USA, UK, Australia, Canada, Germany), you may technically be taxable in both countries, but you can often claim a foreign tax credit in your home country for Cambodian taxes paid. US citizens in particular face complexity — US taxes global income regardless of residency, but can use the Foreign Earned Income Exclusion (FEIE) or Foreign Tax Credit to reduce US liability on Cambodian-taxed income.
