That varies by state. In Georgia it is $20 plus a mailing fee of $1 for the tag itself. My electric car has an over $200 registration fee for the same reasons that are being proposed. I’d need to drive a hilarious distance every year to be on even terms with the gas taxes paid to the state.

On the bright side I pay 1/3 the cost for gas per mile, so there’s still a lot of financial incentive to stick with my EV.
