Thailand Tax Authority i.e. Revenue Department (RD) launched a new electronic tax filing and payment system (The new e-filing system) starting from 6 October 2021.

To use the new e-filing system, taxpayers can go to the Revenue Department’s website (E-Filing) and do the following:

  1. Create a new username, which is the 13-digit corporate registration number, and a new password, for using the new e-filing system. This can be done from 6 October 2021 to 31 December 2021.
  2. Download and install the RD Prep program which is used to save/transfer attachments to withholding tax returns or VAT / specific business tax returns (if filing combined tax returns has been approved). The old program will work with the new e-filing system.

SAP Document and Reporting Compliance generated both PDF form and text file for Thailand VAT Return (P.P.30) and Withholding Tax Return (P.N.D.2, P.N.D.3, P.N.D.53) hence customers can upload and transfer data from text file into RD Prep Program and generate .rdx file which is used to upload into E-Filing website.

For reference – see video “Tax Return Filing by uploading rdx file“.

The following video shows step-by-step of transferring text file generated from SAP Document & Reporting Compliance to RD Prep Program with the sample of Withholding Tax Return (P.N.D.53)

Important: The text file in the video was the file generated from the current software version when the video was made. Text file generated from your system might have different format from text file shown in the video due to different software version either SAP or RD Prep.

Note: this video was made in July 2022 with RD Prep Program version 1.2.3 and SAP S/4HANA Cloud 2208.
