Frequently Asked Questions
Clear answers to common queries regarding electric vehicle taxation.
The one-time tax for electric vehicles is calculated as a percentage of the purchase value (ex-showroom price) based on the rules applicable to the vehicle category and battery type (e.g. Battery Included vs. Battery Renting/Leasing). The rate ranges from 3% to 15% depending on the vehicle category, purchase value slab, and the effective date of the Finance Act version.
Yes. For example, between 01/04/2021 and 31/03/2023, a 50% tax reduction was granted for the first 5 years of the 15-year lifetime tax period, resulting in a net tax rate of 4.2%. Under the revised rules effective from 08/07/2026, entry-level EVs costing up to ₹10 Lakh enjoy a highly concessional rate of 3%.
If you purchase an EV with the battery included, tax rates are determined by purchase value slabs (e.g., 5% to 10% under FA 2025). If the battery is rented or leased separately, FA 2025 introduced a flat 10% tax rate on the purchase value of the vehicle shell/chassis. Under the revised 08/07/2026 rules, they are unified under the same value-based slabs.
The purchase value refers to the ex-showroom price (declared invoice value before GST and registration charges) of the electric vehicle.
