Hello @Vidya_Dhage,
To claim a deduction u/s 80EEB of the income tax act for interest on loan taken for an electric vehicle, the loan should be in the name of the assessee claiming such deduction and the loan should be sanctioned between 01/04/2019 to 31/03/2023.
Hence it is mandatory to have registration and invoice for the EV in your name if you want to claim the deduction.
Hope this helps!
