Built for Cambodian businesses
Know exactly what tax you owe — every month, automatically.
Enter your income, costs and staff. VPK Tax Calculation works out every Cambodian tax for you — patent tax, PTOI, VAT, withholding, payroll and NSSF — plus your year-end liability, in USD and KHR. No accountant, no spreadsheets.
One VPK account works across every VPK app. From $9/week.
Illustrative — your figures depend on your actual income, costs and staff.
Cambodian tax is a maze. Miss one piece and it costs you.
Patent tax, PTOI, VAT, three kinds of withholding, salary tax, NSSF, year-end tax on income, the minimum tax — each with its own rate, threshold and deadline. Get one wrong and you either overpay or face a penalty.
VPK Tax Calculation turns all of it into one number you can trust.
