What This Calculator Does
The Electric Vehicle Tax Calculator computes the One-Time Lifetime Tax (15 Years) for newly registered battery electric vehicles (BEVs) in Kerala under the Annexure of the Kerala Motor Vehicles Taxation Act, 1976 (as amended by Kerala Finance Acts 2021, 2023, 2025, and 2026 revisions).
To accelerate the transition to sustainable e-mobility and reduce urban emissions, the Government of Kerala provides substantial statutory concessions for electric vehicles compared to conventional internal combustion engine (ICE) petrol/diesel vehicles. Furthermore, electric vehicles are permanently exempt from periodic Green Tax surcharges.

2. Slab Matching: The vehicle category and declared purchase value are matched against the statutory percentage rate active on the registration date:
3. Full 15-Year Coverage: Payment of the one-time tax satisfies all motor vehicle tax requirements for 15 years from the initial registration date.
