Vehicle Tax Assessment Criteria

Non-Commercial Passenger Vehicles (Most Common)

Tax is assessed based on engine displacement.

Displacement	Tax per cc
Up to 1,000 cc	$0.07
1,001–1,600 cc	$0.12
1,601–2,000 cc	$0.17
2,001–2,500 cc	$0.19
2,501 cc and above	$0.19

Example: A 2,000 cc vehicle → 2,000 × $0.17 = **$340/year** ($170 each in June and December)

Electric and Hydrogen Vehicles

Because they have no engine displacement, a flat annual rate of $100 applies (as of 2025).

Vehicle Age Reduction

Starting from the third year after manufacture, the tax is reduced by 5% per year, up to a maximum of 50%.

Years Since Manufacture	Tax Reduction
1–2 years	0%
Year 3	5% reduction
Year 5	15% reduction
10+ years	50% reduction (maximum)

Save on Vehicle Tax with Annual Prepayment

Annual prepayment applications are accepted in January, March, June, or September.

Application Month	Discount Rate
January	7%
March	5%
June	2.5%
September	1.25%

Best choice: Apply for annual prepayment every January → save 7%

For a vehicle with $340 in annual tax, January prepayment saves **$24**.
