The U.S. Treasury Department said it will release guidance this week on sourcing requirements for electric vehicle battery tax subsidies under President Joe Biden's climate change law, the first in a string of highly anticipated rules to determine how broadly the credits can be used.
The auto, battery and clean energy industries have been awaiting guidance on complex questions governing eligibility for hundreds of billions of dollars of incentives in the Inflation Reduction Act, signed into law last year.
After outlining battery sourcing rules, officials said, Treasury will follow in the next couple of months with guidance on selling tax credits and making them refundable, which allows entities without tax liability to use them.
Treasury did not specify when the future guidance announcements would be made.
Many of the rules are aimed at weaning the U.S. off dependence on China, which dominates the global supply chains of products like EV batteries and solar panels. Those industries are key to Biden's goal of decarbonizing the U.S. economy and fighting climate change.
The IRA specifices, for instance, that a $7,500 EV tax credit is only available to North American-assembled vehicles that meet certain local battery production and mineral extraction processing standards.
