The Signboard / Advertisements Tax: Update and Deep Dive on the New Prakas


The new Prakas dated 20 March 2024 on the Signboard or Advertisements Tax comes as many enterprises struggle with tax reassessments and penalties related to all types of advertising. The General Department of Taxation (GDT) has issued new rules to determine which advertising or signs trigger this tax, and which ones do not. Besides what is subject to tax, major other aspects are also often disputed. Such as, who owes this tax if the advertisement concerns several parties such as a principal and its agents? A lot of practical questions and issues, worthy of a deep dive.

In this highly practical physical breakfast seminar, VDB Loi experts will take you through a systematic, thorough analysis of the Advertisement Tax with a special focus on the changes since the new Prakas of 20 March 2024.
