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.

Everything Cambodian tax throws at you, handled

You enter the real-world facts of your business. The engine applies the rules and shows you the result.

Every tax, calculated for you

Patent tax, PTOI, VAT, withholding tax, salary tax, NSSF, year-end tax on income and the minimum tax — all worked out from what you enter.

Your taxpayer class, automatically

Small, medium or large is decided for you from your turnover — so the right rules, thresholds and rates are always applied.

Monthly and year-end, side by side

See exactly what's due this month and a clear estimate of your annual liability, so nothing sneaks up on you at year-end.

Payroll done right

Tax on salary, NSSF and fringe benefits per employee — with dependent relief — so your staff costs and withholdings are correct.

Withholding tax & treaties

Foreign-digital, rent and local-service withholding handled — including reduced DTA rates when a tax treaty applies.
