Cambodia Annual and Monthly Tax Filing 2020


The Cambodian General Department of Taxation (GDT) has issued Instruction 7705 on March 19th 2020, which allows for Cambodian taxpayers to use the e-tax service to pay their monthly tax returns from February 2020 through to June 2020.

What is GDT’s e-Tax service?

GDT’s e-Tax service allows taxpayers to scan and deliver their monthly and annual tax returns through the GDT’s e-tax service online.

The GDT Instruction was sent as a means to deal with the current COVID-19 outbreak and minimise human contact and promote responsible social distancing thus rather than having to physically go to a General Department of Taxation office to submit the returns.

DFDL said that the process involves “simply scanning the tax returns and other related documents and upload the scanned documents to the GDT.”

In addition, the GDT can be contacted via their Call Center 1277. Their website also has a live chat feature and the app can be downloaded for iOS and Android.

After receiving the above email from the GDT, the taxpayer shall be considered to have completed the filing of the tax returns.
