Environmental Performance Tax Calculator (Japan)
Enter the vehicle price and fuel efficiency achievement tier to estimate Japan's Environmental Performance Tax, a one-time tax charged when you acquire a car. Supports the lower rate cap for kei (light) cars.
What the environmental performance levy was
The environmental performance levy was a Japanese tax charged once, on acquiring a vehicle, introduced in October 2019 in place of the earlier vehicle acquisition tax. The rate fell into four bands — 0%, 1%, 2% and 3% — according to how far the vehicle met the fuel economy standards, so that the cleaner the vehicle, the lighter the charge. Electric and fuel-cell vehicles were exempt. The taxable base was roughly 90% of the list price of the vehicle itself.
The levy was abolished on 31 March 2026 under the fiscal 2026 tax reform. Vehicles acquired on or after 1 April 2026 are not charged. This tool exists to check the tax on a vehicle acquired before that date. Use it when you want to verify the breakdown of costs on a past purchase, or to sort out how a used-car transaction is treated depending on when acquisition occurred. It also reflects the separate rate ceiling that applied to light vehicles.
Sources used in this calculation
Statutory figures such as tax and insurance rates come from the public bodies listed below. They change when the law is revised, so please also check the primary source before relying on the result for an important decision.
- Environmental performance levy rates and taxable base (abolished 31 March 2026) — Ministry of Internal Affairs and Communications (総務省) Effective 2019-10 to 2026-03 ／ Last checked 2026-09-21
How to check the amount
- Choose the vehicle category The rate ceiling differs between ordinary or small passenger cars and light vehicles.
- Enter the list price of the vehicle The taxable base is converted automatically at roughly 90% of that price.
- Choose the fuel economy band Select exempt, 1%, 2% or 3%, judging from the fuel economy figure in the catalogue or on the inspection certificate.
- Read the amount The tool shows the amount derived from the taxable base and the rate.
Tips for getting more out of it
- Enter the vehicle price using the tax-excluded manufacturer's suggested retail price or catalog price. The officially certified taxable base can vary depending on whether optional equipment is included.
- Check the fuel efficiency achievement tier for your specific grade against the tier table published by Japan's Ministry of Land, Infrastructure, Transport and Tourism.
- Most EVs, fuel-cell vehicles (FCVs), plug-in hybrids (PHVs), and qualifying natural gas vehicles fall into the tax-exempt tier.
- Kei cars are capped at a 2% rate, so a kei car can sometimes have a lower tax burden than a standard car with the same fuel efficiency tier that would otherwise fall into the 3% bracket.
- The existing vehicle tax calculators estimate the tax charged every year you own the car, while this tool estimates the one-time tax charged only when you acquire it.
Where this helps
Verifying the costs on a past purchase
Lets you check after the fact whether the amount shown on an estimate or invoice was reasonable.
Sorting out used cars by date of acquisition
Treatment changes across the abolition date, so you can establish the assumptions for each period.

Vehicle tax terms explained
- Environmental performance levy
- A tax charged once on acquiring a vehicle. It was abolished on 31 March 2026.
- Vehicle acquisition tax
- The predecessor of the performance levy, charged until the end of September 2019.
- Taxable base
- The amount on which the tax is computed. In practice it was set per model by the acquisition value tables published by the state.
- Fuel economy attainment
- How far a vehicle met the fuel economy standards set by the state. It determined which rate band applied.
- Annual vehicle tax
- The yearly tax on holding a vehicle — a separate tax from the performance levy and not affected by the abolition.
- Vehicle weight tax
- A tax charged at inspection according to the weight of the vehicle. It too continues separately.
Frequently asked questions
Side Note — From Automobile Acquisition Tax to Environmental Performance Tax
The Environmental Performance Tax is a relatively new tax, introduced in October 2019 alongside the consumption tax rate increase to 10%, replacing the long-standing Automobile Acquisition Tax. Rather than a simple rename, the rate structure builds in a clear policy intent: vehicles with better fuel efficiency are taxed at a lower rate, or not at all, to encourage buyers to switch to more environmentally friendly cars.
The tax tiers are based on how well a vehicle achieves the "FY2030 fuel efficiency standard," a forward-looking target, so the tiers have been revisited over time as more models meet the bar. When the system launched, many mainstream gasoline cars fell into the 1% tier, but the bar for each tier has generally risen year by year as technology has improved.
Unlike the annual vehicle tax, which is charged every year you own the car, the Environmental Performance Tax is a one-time charge at acquisition, so its share of your total tax burden shrinks the longer you keep the car. Conversely, drivers who trade in their cars frequently feel a proportionally larger impact from the rate tier each time they acquire a new one.
