Tax residency of a company

What is a resident taxpayer in Cambodia?

A resident taxpayer is a company that is organised or managed in Cambodia or has its principal place of business in Cambodia.

What is a non-resident taxpayer?

A non-resident taxpayer is deemed to have a permanent establishment in Cambodia if there is a fixed place of business, a branch of a foreign company which the non-resident person carries on their business, also includes online such as e-commerce activities, if the goods or services are supplied or used in Cambodia and the business activities (including heavy equipment operations) for one or more exploration or business of natural resources for the total more than 90 days at a time or more in any 12 months period will be considered as having a PE in Cambodia.

Worldwide income and Cambodia-sourced income

Resident taxpayers are subject to tax on worldwide income, while non-resident taxpayers and branches are taxed on income sourced in Cambodia.

Year of assessment and corporate tax return filing

What is the year of assessment in Cambodia?

The year of assessment (YA) for companies in Cambodia is the calendar year, from 1 January to 31 December.

When to submit corporate income tax return in Cambodia?

The annual tax return must be filed within three months after the tax year-end. The corporate income tax or minimum tax liability can be reduced by prepayment of corporate income tax payments.

Monthly returns must be paid by the 20th of the following month. However, if the 20th falls on a weekend or a public holiday, the deadline will be extended to the next working day.

Prepayment of corporate income tax

The prepayment of corporate income tax (CIT) is calculated as 1% of the company’s turnover in the previous months. It is required to be paid monthly.

If the taxpayer is in the tax holiday period, the taxpayer is also exempted from the prepayment obligation, but a nil monthly return must be lodged.

What is minimum tax?

Minimum tax is separate from the CIT and imposed at a rate of 1% on annual turnovers. If the CIT is less than the minimum tax, then the company must pay the minimum tax. The prepayment paid for the year will be equal to the minimum tax of the company.

If the CIT is lower than the prepayment of CIT payments, then no refund is due to the taxpayer as the prepayment of CIT will be used to offset the minimum tax obligations. Companies that maintain proper accounting records are exempted from minimum tax. The criteria for maintaining proper accounting records and procedures of the minimum tax will be determined by the Prakas of the Ministry of Economic and Finance.
