How much tax on a 1,500 cc car?

1,650 baht a year: 600 cc × 0.50 = 300 plus 900 cc × 1.50 = 1,350. In year 6 it is 10% less, 1,485 baht.

How much off for an older car?

Section 29 of the Motor Vehicle Act gives cars up to 7 seats registered for 5 years 10% off in year 6, rising 10% a year to 50% from year 10.

Private trucks are taxed by the weight on the registration book, e.g. 1,050 baht for 1,501–1,750 kg, with no older-car discount.

1% of the tax per month, a part month counting as a month. After more than a year unpaid, the vehicle needs a private inspection first.
