WASHINGTON, Oct 1 (Reuters) - The U.S. government has issued $2 billion in advance point-of-sale consumer electric vehicle (EV) tax credit payments since Jan. 1 covering more than 300,000 vehicles, the Treasury said on Tuesday.

Since new rules took effect this year allowing for consumers to take advantage of EV tax credits worth up to $7,500 at the point of sale, more than 250,000 tax credits have been issued for new EVs and around 50,000 for used models that carry up to $4,000 rebates.

Nearly all involve transferring the credit to a car dealer at the time of purchase resulting in a significant rebate.

The 2022 Inflation Reduction Act created the point of sale rebate as well the used EV tax credit, lifted 200,000-vehicle manufacturer caps on credits, imposed income and vehicle price restrictions and extended credits to leased vehicles.

It also imposed new restrictions designed to wean the U.S. EV and battery supply chain away from China including requiring all EVs be assembled in North America to qualify for credits.
