Quick Takeaways
- Japan’s FY2026 car tax reform removes acquisition-stage environmental taxes to lower upfront vehicle costs and simplify taxation.
- Extended eco-car and weight-tax incentives sharpen the focus on real-world efficiency while managing rising vehicle mass.
On December 19, Japan’s ruling coalition unveiled the Japan car tax reform FY2026, outlining significant changes to the automobile tax framework for the fiscal year beginning in April 2026. Announced jointly by the Liberal Democratic Party and the Japan Innovation Party, this is the first tax guideline issued under the current coalition government and sets a clear policy direction for cleaner mobility and fairer vehicle taxation.
Japan Car Tax Reform FY2026 and the End of Environmental Auto Tax
A central measure in the Japan car tax reform FY2026 is the complete abolition of the environmental performance-based automobile acquisition tax at the end of March 2026. While an earlier proposal considered only a temporary suspension, the final decision confirms a permanent removal, easing upfront costs for vehicle buyers across segments.
This change reflects growing political consensus to simplify vehicle taxation while supporting the transition toward low-emission mobility without relying on acquisition-stage levies.
Extension of Eco-Car Tax Reductions With Stricter Criteria
The guideline also extends the eco-car tax reduction scheme by an additional two years. However, the extension will be accompanied by tighter eligibility standards, ensuring that incentives are more closely aligned with real-world environmental performance.
Key points include:
Vehicle Weight Tax Benefits for Electrified Vehicles
Under the Japan car tax reform FY2026, vehicle weight tax reductions will remain in place for electric vehicles, fuel-cell vehicles, and plug-in hybrid vehicles. These reductions will apply through the second mandatory vehicle inspection, maintaining long-term ownership incentives for electrified models.
This approach balances higher manufacturing costs of advanced powertrains with ongoing tax relief during early years of vehicle ownership.
Special Green Tax Provisions and New Additional Tax From 2028
The special green tax provisions will also be extended by two years, in line with the existing schedule. At the same time, policymakers introduced a notable future adjustment: a special additional vehicle weight tax targeting heavier electrified vehicles.
From May 2028:
This dual approach signals a shift toward balancing electrification with broader efficiency considerations.
Overall, the Japan car tax reform FY2026 represents a comprehensive recalibration of automotive taxation. By removing acquisition taxes, extending targeted incentives, and introducing weight-based adjustments, the framework supports cleaner technologies while encouraging manufacturers and consumers to consider efficiency alongside electrification.

Key points include:
- Continued tax benefits for vehicles meeting higher efficiency and emissions benchmarks
- A stronger policy signal favoring advanced electrified powertrains
- Gradual tightening to prevent incentive dilution over time

From May 2028:
- Electric vehicles exceeding average vehicle weight levels will face higher weight-based taxation
- Plug-in hybrid vehicles will be taxed at roughly half the additional rate applied to electric vehicles
- The policy aims to address concerns over increasing vehicle mass while preserving electrification incentives
