Three Books For Small Taxpayers: What It Is and How To Use It


Over the last few years, the General Department of Taxation (GDT) has strengthened the tax collection in the Kingdom of Cambodia. The designation of the Small Taxpayer who was previously estimated regime taxpayers, were now directed to submit the Small Taxpayer monthly tax return and pay the relevant taxes such as VAT, Tax on Salary, Withholding Tax on rental, etc. by 20th of the following month.

Moreover, following Prakas 1820 a Small Taxpayer can use a simple accounting system that allows single-entry accounting, therefore a business can record income on a cash basis rather than an accrual basis.

On 25 December 2015, the Ministry of Economic Finance [MoEF] issued Prakas no. 1820 to provide further rules and procedures for the implementation of the simplified accounting for small taxpayers mentioned in the introduction above.

The objective of this Prakas is stated to provide guidance on the simplified accounting requirements in order to facilitate the Small Taxpayer’s accounting practices. In summary, Prakas 1820 stipulates that the Small Taxpayer is required to maintain 3 simplified accounting books as outlined below, and submit to the General Department of Taxation every month before the 20th calendar date:
