In Thailand, the tax term of a motor vehicle starts on the first registration day and lasts for one year. Thus, each motor vehicle has its unique tax due date every year.
The annual tax for a motorcycle is 100B, regardless of its engine displacement. You must pay the tax before the due date; Otherwise, you will be charged extra 1% tax in arrears per delayed month. You can pay the tax from three months before the tax due date.
To pay the vehicle tax, you need to bring the registration book to a local Land Transport Office. You also need to bring either the current insurance policy or insurance sticker for presentation. There are five Land Transport Offices in Bangkok (ref. Land Transport Office Map), and each province has at least one such Office. Or you may choose to pay at a post office. Upon payment of tax, you will receive a tax sticker.
From the fifth renewal of the tax sticker for motorcycles (seventh renewal for cars), you must have your motorcycle inspected at an authorized inspection site, and turn in the Certificate of Inspection upon paying the tax (Private Motor Vehicle Inspection).
Example of Inspection Schedule --- May 1996 ... registered May 1997 ... 1st renewal May 1998 ... 2nd renewal May 1999 ... 3rd renewal May 2000 ... 4th renewal May 2001 ... 5th renewal (requires inspection) May 2002 ... 6th renewal (requires inspection) ....
There are usually several such inspection sites near a Land Transport Office - look for a yellow cogwheel logo (shown on the right).The inspection itself is simple and costs 60B for a motorcycle and 150B for a car. But the whole process of locating a Land Traffic Office and an inspection site in an unfamiliar area can be tedious and time-consuming, especially in Bangkok. An alternative is to ask a motorcycle shop to handle it for you. Some motorcycle shops can take care of renewing your tax sticker, as well as taking care of the mandatory inspection, if you know what I mean, for a fee of 400B - 500B. Or else, the tax sticker renewal can be processed at any Land Traffic Office in any province, regardless of your registered address written in the registration book, so you can take care of it outside Bangkok if it's convenient for you.
