Biden's EV tax credit just got a major change to help you buy a car — but way fewer options are available

• The rules around the EV tax credits changed for 2024. 
• The $7,500 (or $3,750) rebate can now be taken at the time you buy a car. 
• But there are a lot fewer options as supply-chain rules get stricter. 

The rules for lucrative tax credits that can effectively lower the price of an electric vehicle by up to $7,500 became more strict on January 1, meaning fewer vehicles are likely to be eligible.
