Salary in USD, taxes in KHR
Many expatriate contracts are denominated in USD, but the tax on salary is calculated and remitted in KHR. Use the MEF rate of the pay date to convert the gross salary into KHR before computing tax.
NSSF contributions
Contributions to the National Social Security Fund are KHR-based with a capped salary threshold. Apply the cap after conversion, not before.
Reporting
Provide each employee with a payslip showing the gross USD amount, the rate used, the KHR equivalent, and all deductions. This eliminates disputes and supports your tax filings.
How to Verify the MEF Rate for Your Filing
Whether you are posting a USD invoice, computing month-end FX revaluation, or preparing a customs declaration, the rule is the same: anchor your figure to the official MEF daily bulletin for the relevant valuation date. Use today's official MEF rate from the Cambodia Exchange dashboard for live work, or pick any past date to retrieve the exact rate that applied on that day. Archive the rate evidence (a screenshot or API response) alongside the supporting document — GDT auditors increasingly request the source for every FX translation.

Frequently Asked Questions
- Which exchange rate applies to a USD-denominated salary paid in KHR?
- Translate the gross USD salary to KHR using the MEF rate for the pay date for tax and payroll filing purposes. The actual bank conversion rate may differ slightly; that difference is an FX item in your ledger, not in payroll.
- Do statutory deductions need to be in KHR?
- Yes. Cambodian payroll taxes and social security contributions are filed and paid in KHR even when the underlying salary is contracted in USD. The KHR equivalent is calculated at the MEF rate for the pay date.
- How can I make payroll FX more predictable for staff?
- Set a clear contractual rule — for example, fix the conversion rate at the start of each month, or always use the MEF rate of the pay date — and document it in the employment contract so expectations match what lands in the bank account.
