No, you can't normally claim the EV tax credit without the Clean Vehicle Sales Report from the dealer. You can contact the dealer and request the form. Per the IRS "When you take possession of the vehicle, the seller must give you a time-of-sale report and a copy of the confirmation the IRS provides when it accepts the time-of-sale report submitted through IRS ECO". More details on the requirements can be found at IRS EV Credit Guidelines.
