Do You Need to Pay Taxes After Registering Your Business in Cambodia?

Registering your business in Cambodia is just the beginning. Once you’re officially recognized by the Ministry of Commerce and the General Department of Taxation (GDT), the next big question is:
 Do you need to pay taxes right away?

Short answer—Yes. Every registered business in Cambodia is required to fulfill monthly and annual tax obligations. In this blog, GIANTBROTHER breaks down the types of taxes you need to pay, when to file, and how to stay compliant.

Why Paying Taxes Is Mandatory in Cambodia

Once your business is registered, the GDT assigns you a Tax Identification Number (TIN), and from that point forward, you’re legally obligated to declare your business income—even if you haven’t started generating profits yet.

Paying taxes ensures:

  • Legal operation and protection
  • Eligibility for VAT invoices
  • Avoidance of penalties or shutdowns
  • Business credibility with partners and banks

Types of Taxes Cambodian Businesses Must Pay

1. Monthly Tax Declaration

Businesses are required to declare the following every month:

  • Value-Added Tax (VAT) – 10% on goods and services (if VAT-registered)
  • Withholding Tax (WHT) – Usually 10–15% on payments to suppliers or service providers
  • Prepayment of Profit Tax (PPT) – 1% of monthly turnover

These reports must be filed with the GDT by the 20th of every month.

2. Annual Tax on Profit (ToP)

This is the final tax based on your yearly net profit, filed within 3 months after the end of the fiscal year. The rate is typically:

  • 20% for standard companies
  • 0% for qualified SMEs under the incentive law (subject to conditions)

3. Patent Tax (Annual Business License Fee)

Paid once a year, this fee depends on your business size and sector. It ranges from 400,000 to 1,200,000 KHR.

What Happens If You Don’t Declare?

Failure to declare taxes on time can result in:

  • Heavy penalties and interest
  • Business license suspension
  • Loss of reputation with banks and partners

Even if your business made zero income, you’re still required to file a zero declaration.
