Every Entity subject to Tax (Top-Up Tax) in the State must register, and such Entities must also be registered as a group. The Tax Administration issues a tax card and a TRN for each Entity and/or Group registered with it. The registrant must include their TRN on all correspondence with the Tax Administration.
The provisions of the law apply to all Taxpayers starting from the date they become subject to Tax (Top-Up Tax), even if they are registered after this date.
