A Georgia lawmaker wants the state to reinstate tax credits for the purchase of electric vehicles, less than a year after a previous program ended.

Rep. Margaret Kaiser, D-Atlanta, this week filed House Bill 877, which would impose smaller credits for the purchase of plug-in vehicles. The tax credits would expire for good on Dec. 31, 2019.

Georgia had been a national leader in the sales of electric vehicles, thanks in large part to a $5,000 tax credit. But lawmakers last year eliminated the program and imposed an annual $200 registration fee on cars like the Nissan Leaf. Since then, sales here have plummeted.

Kaiser would offer up to a $3,000 tax credit for plug-in cars through 2017, and $2000 through 2019.

The bill comes as advocates urge lawmakers to study ways to encourage the purchase of electric and other alternatively fueled vehicles.
