Cambodia’s workforce, estimated at over 9 million, is spread across urban centers such as Phnom Penh, Siem Reap, and Sihanoukville. Local and international businesses employ them and typically pay them monthly, as stipulated in their employment contracts. The Cambodian economy has witnessed an impressive increase in the first quarter of 2025, with 457 new enterprises registered.

Labor unions play a role in negotiating collective agreements, particularly for minimum wages, which vary by sector, However, the standard minimum wage is $210. Tax residents are subject to the Tax on Salary (ToS), a progressive tax ranging from 0% to 20%, based on income levels.

If you intend to set up a local presence in Cambodia, compliance with payroll and tax regulations is essential to avoid penalties and build trust with employees. For local companies, adherence to tax laws prevents fines and audits from the General Department of Taxation (GDT). For international firms, compliance enhances credibility with the Cambodian government and strengthens market presence.

What Is Payroll Tax in Cambodia?

Definition and Purpose of Payroll Tax

In Cambodia, payroll tax primarily consists of social security contributions managed by the National Social Security Fund (NSSF) under the Ministry of Labour and Vocational Training. These contributions fund benefits like healthcare, maternity leave, pensions, and occupational risk coverage for millions of workers.

Employer and Employee Responsibilities

Employers contribute 2.6% of an employee’s gross monthly salary, covering occupational risk (0.8%) and healthcare (1.3% from employers, matched by 1.3% from employees). Pension contributions, phased in since 2022, require 2% from employers and 2% from employees, increasing to 4% each in the next phase (2027–2031).

Employers also withhold ToS monthly based on a progressive rate of 0% to 20% for residents. Non-residents face a flat 20% rate on Cambodian-sourced income.

Employers are also responsible for fringe benefits tax (FBT): Fringe benefits, such as housing or transportation allowances, are taxed at a flat 20% based on their fair market value.

Employers must register with the GDT within 15 days of starting operations and file monthly ToS and FBT declarations by the 20th of the following month via the GDT’s e-filing system. Employees should verify payslips to ensure accurate deductions. Non-compliance, such as late filings or underreporting, incurs penalties of 10%, 25%, or 40% plus 1.5% monthly interest on unpaid taxes. Employers bear the penalty, not employees.

Contribution rates and regulations may change, so check the GDT website or NSSF announcements for updates. Partnering with a local PEO or payroll service provider can simplify compliance.

For companies seeking to simplify compliance, partnering with a Cambodian Employer of Record (EOR) can make the process easier. Alternatively, you can use a Cambodian PEO service for payroll management to take care of everything from employee salaries to benefits administration.

Employer Payroll Tax Rates in Cambodia

Payroll taxes are calculated as a percentage of an employee’s gross salary, balancing business obligations with social welfare funding.

Breakdown of Employer Contributions

  • Social Security Contributions (NSSF)
    • Occupational Risk: 0.8% of gross salary.
    • Healthcare: 1.3% of gross salary (employees contribute an additional 1.3%).
    • Pension: 2% of gross salary (matched by 2% from employees), increasing to 4% in 2027.
    • Total: 4.1% currently, rising to 5.3% in 2027.
  • Tax on Salary (ToS): Withheld by employers at progressive rates (0%–20%) based on monthly salary after deductions for dependents (KHR 150,000 per non-working spouse or child under 14, or 25 if a full-time student).
  • Fringe Benefits Tax (FBT): 20% on the fair market value of benefits like housing or meal allowances.

Industry-Specific Considerations

  • Garment and Footwear Sector: A minimum wage of $210 per month applies, with additional allowances (e.g., $10 attendance bonus, $7 transport/accommodation allowance). These may be exempt from ToS if specified in labor contracts.
  • Investment Incentives: Qualified Investment Projects (QIPs) in Special Economic Zones (SEZs) may receive ToS exemptions or reduced rates for up to 9 years, as per the Cambodian Investment Law. Contact the Council for the Development of Cambodia (CDC) for eligibility.

Allowances like health/life insurance premiums (if provided to all employees) and certain factory worker allowances are exempt from ToS.

Employers must budget for mandatory contributions and consult local tax experts or the GDT for clarity on exemptions. 

Overview of Income Tax in Cambodia

Cambodian residents are taxed on their worldwide income, while non-residents are taxed only on Cambodian-sourced income. The Tax on Salary (ToS), overseen by the General Department of Taxation (GDT), is the primary personal income tax for employees. 

Personal Income Tax Brackets and Rates

The ToS follows a progressive system, with rates based on monthly taxable income (in Khmer Riel, KHR):

Monthly Income (KHR) Tax Rate Deductible Tax (KHR)
Up to 1,300,000 0% 0
1,300,001 – 2,000,000 5% 80,000
2,000,001 –8,500,000 10% 191,250
8,500,001 – 12,500,000 15% 1,066,250
More than 12,500,000 20% 2,316,250

Non-residents face a flat 20% withholding tax on Cambodian-sourced income, such as salaries, with no deductions. Residents file annual ToS returns by March 31 of the following year via the GDT’s e-filing system. Capital gains are generally not taxed for individuals unless derived from business activities.

Tax-Free Allowances and Deductions

Cambodia’s tax system offers deductions to reduce taxable income:

Deduction or Exemption TypeDetails
DependentsKHR 150,000 per month per dependent (non-working spouse or child under 14, or under 25 if a full-time student)
Social Security ContributionsEmployee contributions to the National Social Security Fund (NSSF) — 1.3% for healthcare, 2% for pensions — are deductible
Fringe Benefits ExemptionsCertain benefits, like uniform allowances or health insurance provided to all employees, may be exempt from the Fringe Benefits Tax (FBT) if specified in labor contracts
Other AllowancesSpecific allowances in sectors like garments (e.g., $7 transport/accommodation allowance) may be exempt from ToS if documented

Key Components of Payroll in Cambodia

Payroll Cycle and Pay Slips

Cambodia follows a monthly payroll cycle, with salaries paid by the last working day or early the following month. Bonuses, such as seniority payments or festival bonuses, are common in industries like garments and are processed separately.

Employers must provide monthly pay slips detailing:

  • Basic salary
  • NSSF contributions (1.3% healthcare, 2% pension from employees)
  • ToS withheld
  • Fringe benefits (taxed at 20% of fair market value)
  • Other deductions or allowances

Pay slips must comply with GDT regulations and are often submitted via the e-filing system.

Employer Responsibilities for Payroll Tax Compliance

Employers are responsible for:

  • Withholding ToS based on the progressive rates and remitting by the 20th of the following month.
  • Paying Fringe Benefits Tax (FBT) at 20% on non-exempt benefits like housing or transportation allowances.
  • Contributing to NSSF
    • 0.8% for occupational risk
    • 1.3% for healthcare
    • 2% for pensions (rising to 4% by 2027).
  • Registering with the GDT within 15 days of starting operations and filing monthly declarations via the e-filing system.

Common Payroll Errors and How to Avoid Them

  • Misclassifying Employees: Employees and freelancers have different tax obligations. Verify classifications using Cambodian labor laws to avoid penalties.
  • Incorrect Tax Calculations: Errors in ToS or FBT calculations can lead to fines. Use payroll software or consult local tax experts.
  • Non-Compliance with NSSF: Failing to register or contribute to NSSF incurs penalties. Ensure timely registration and accurate contributions.
  • Poor Record-Keeping: Inadequate records can complicate GDT audits. Adopt digital solutions to maintain organized payroll records.

Tax Treaties and Withholding Taxes

Cambodia’s Double Taxation Treaties

Cambodia has double taxation agreements (DTAs) with countries like Singapore, Thailand, and China to prevent double taxation. These allow tax credits for foreign taxes paid on Cambodian-sourced income, capped at the ToS liability. Employers and employees must submit documentation to the GDT to claim credits. Verify applicable treaties via the GDT website.

Totalization Agreements

Cambodia has limited social security totalization agreements, primarily with ASEAN countries. These prevent double contributions for expatriates, ensuring contributions to only one country’s system (e.g., Cambodia’s NSSF or the home country). Confirm agreements with the NSSF to avoid overpaying.

Withholding Tax on Foreign Income

Non-residents face a 20% withholding tax on Cambodian-sourced income, including salaries and services. Dividends, royalties, and interest paid to non-residents are subject to a 14% withholding tax, unless reduced by a DTA. Employers must file withholding tax returns by the 20th of the following month via the GDT’s e-filing system.
