1. Check the safety of installing advertising signs
Checking the safety of installing advertising signs is very important to prevent accidents that may arise from improperly or unsafely installed signs. Therefore, before we install a new advertising sign, we should check as follows:

Check that the size of the advertising sign meets our requirements, especially when installing in public spaces such as roads, bridges, sports fields, etc. The size also needs to be appropriate for the area.
Check the photographs or sketches of the advertising sign
We should send photographs or sketches of the advertising sign we want to install to the local office, municipality, or sub-district administrative organization to ensure they understand and verify that the design and features of the sign comply with the law. This is to ensure that our advertising sign does not pose a risk to the life and property of passersby in the area.
Check the layout plan of the area where the advertising sign will be installed
Check that the area we want to install the sign is public and whether it is suitable for installing the advertising sign.
Check the installation of the advertising sign
Once permission has been granted, we start the installation process. At this stage, we should conduct a detailed check of the sign installation to ensure that there are no errors, and that it follows the layout submitted to the public organization correctly. This is for the safety of road users and the lives of people living in the area. If issues or errors are found during the installation, we should notify the sign company or the public organization that issued the permit for us to correct them beforehand. During this stage, we may have to pay additional fees if changes or corrections are required.
Maintaining the advertising sign
After completing the installation of the advertising sign, maintaining it to keep it looking good and in good condition is also very important. The maintenance of the advertising sign can be done by regularly cleaning it to prevent dirt or grime accumulation and inspecting the condition of the advertising sign regularly for the safety of road users and residents in the area.
In addition to checking the safety of the sign installation, do not forget to consider the materials used for manufacturing the sign, ensuring they are durable against various weather conditions and environments. It is also crucial to check that the sign is bright enough to be read and understood easily by passersby, especially during nighttime, such as when installing electric or LED signs that require checks for safety and proper electrical usage to prevent future accidents.

2. Submit documents for paying advertising sign tax
After receiving permission to install the sign, prepare the following complete documents for filing the advertising sign tax:
- National ID card
- Copy of house registration
- Value-added tax registration
- Certificate of partnership
- Sign installation permit or receipt from the sign shop
If we have previously submitted a file for advertising sign tax, we should also bring the previous year's sign tax receipt to show.
If we have previously submitted a file for advertising sign tax, there is no need to bring the previous year's tax receipt to show again, but do keep it as evidence for confirming the previous year's tax payment. Also, other relevant documents such as the receipt or evidence of payment for the current year's advertising sign tax should be presented when filing the tax declaration. If any changes occurred to the sign during that year, we must submit a new advertising tax declaration to assess the new tax amount and pay the tax as re-evaluated, whether it is an increase or decrease in the number of signs or changes in the location or appearance of the sign.
For paying the advertising sign tax, if it is the first year the sign has been filed and is assessed to have a tax exceeding 3,000 Baht, it can be paid in 3 installments, each installment spaced 3 months apart without interest. However, if it exceeds 3 installments, interest will be charged.

3. Payment of advertising sign tax must be done annually, by March of every year
The payment of advertising sign tax must be done annually, and it should be paid by March of each year. The person liable for paying the advertising tax is the owner of the sign. However, if there is no one to file the advertising sign tax declaration (Form P.P.1) or if the sign owner cannot be located, the person occupying the sign, whether the building, location, or land on which the sign is installed or displayed, will be deemed to be liable for the advertising tax. The tax assessment notice must be sent in writing to such persons. Therefore, those liable for the advertising sign tax should be responsible for paying the tax according to the law to promote local development and sustainable environmental practices.
All of this constitutes the basic procedures for requesting permission and installing signs in public places.
