The differences between the old and new e-filing systems are summarized below:


Old e-filing system

New e-filing system

1. VAT / SBT registration

Can register for filing by branch only.

Can register for fling by branch or combine all branches.

2. Registration for service providers

Not applicable

Can register for providing services consisting of preparing and filing tax return, so that a taxpayer using such services is not required to register for filing a tax return with the Revenue Department.

3. Tax return filing

To use the new e-filing system, taxpayers can go to the Revenue Department’s website ( 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.
