1. The owner of the signboard; or

2. In the absence of a tax filing or the officer cannot find the owner of that signboard, the tenant that hosts the signboard.

2. Signboards displaying both Thai and foreign words and/or pictures are taxed at Baht 20 per 500 square centimeters;

3. Signboards that display foreign words alone with a picture or logo are taxed at Baht 40 per 500 square centimeters; and

A minimum signboard tax of Baht 200 is payable.

Tax calculation

Regardless of the signboard’s shape, the area is calculated from the widest and tallest points on the signboard.

Signage tax is calculated as:

Tax payable = (Width in sq cm x Length in sq cm) / 500 sq cm × signage rate

A signboard containing both Thai and foreign words and covering an area of 10,000 square centimetres.

10,000 sq cm / 500 sq cm = 20

20 x Baht 20 = Baht 400
