Why Salary Tax Matters in Cambodia
Whether you are starting a new job, comparing offers, or checking a monthly payslip, your gross salary is only the beginning. Cambodia's Tax on Salary (TOS) is usually withheld by the employer each month, so employees often see the result as one line on their payslip rather than as a full calculation.
The Cambodia Salary Tax Calculator helps you estimate that calculation before payday. Enter your gross monthly salary, choose KHR or USD, select your residency status, add eligible dependents, and the tool estimates your tax deducted and net take-home pay.
Cambodia Tax on Salary in 2026
For resident employees, Cambodia uses progressive monthly tax brackets — each portion of your taxable salary is taxed at its own rate (0%, 5%, 10%, 15%, or 20%), depending on which band it falls into. Non-resident employees are taxed at a flat 20% rate on Cambodia-sourced salary.
For the full bracket table with worked examples and effective-rate calculations, see our companion guide: Cambodia Salary Tax Brackets 2026.
Resident vs Non-Resident
Your residency status determines how salary tax is calculated:
- Resident employee: progressive brackets apply, and eligible dependent deductions can reduce taxable salary.
- Non-resident employee: a flat 20% rate applies to Cambodia-sourced salary, without the resident progressive bands.
If you are an expat, contractor, or employee moving in and out of Cambodia during the year, ask your employer or tax adviser which status applies to your payroll.
Dependent Deductions
Resident employees may deduct 150,000 KHR per month for each eligible dependent child or a non-working spouse. The calculator subtracts this amount before applying the progressive resident tax brackets.
For a full explanation of how dependent deductions interact with each bracket, see Cambodia Salary Tax Brackets 2026.
How to Use the Salary Tax Calculator
- Open the Cambodia Salary Tax Calculator.
- Choose whether your salary is entered in KHR or USD.
- Enter your gross monthly salary before tax.
- Select resident or non-resident.
- Add eligible dependents and a non-working spouse if applicable.
- Review the estimated tax deducted, effective rate, and net salary.
The result is useful for planning, but it is still an estimate. Exchange rates, benefits, payroll policies, and official updates can affect final payroll.
Example: Reading Your Result
If your gross salary is 4,000,000 KHR and you are a resident employee with no dependents, the calculator applies the 0%, 5%, and 10% bands only to the portions of income that fall in those ranges. It does not apply 10% to the whole salary.
That progressive method is why two salaries in the same highest bracket can have different effective tax rates. The result panel shows both the total tax deducted and the effective rate so you can understand the real impact on take-home pay.
When This Tool Is Useful
- Checking whether a payslip deduction looks reasonable
- Comparing a gross salary offer with expected net pay
- Planning monthly household income
- Helping HR or payroll teams explain TOS to staff
- Understanding how dependent deductions change taxable income
- Estimating tax for Cambodian employees and expats
Important Notes
The calculator is based on the published Cambodia Tax on Salary brackets and dependent deduction rules used for 2026. It does not replace official tax advice, and it does not calculate every payroll item, such as NSSF contributions, fringe benefits, bonuses with special treatment, or employer-specific deductions.
For compliance, always confirm current rules with the General Department of Taxation, your employer, or a qualified tax adviser.
