Disaster Zone Energy Affordability and Investment Act

This bill modifies tax credit rules to help businesses recover after disasters. It allows businesses operating in designated disaster areas to treat certain unused tax credits (carryforwards) as transferrable credits against current tax liability, rather than letting them expire. Specifically, it applies to taxpayers making eligible expenditures for business operations in areas with a major disaster declaration after December 31, 2023, or a state-declared disaster meeting specific criteria. The change affects businesses in affected zones by providing immediate tax relief for qualifying expenses incurred within two years of the disaster declaration. It does not involve energy policy or new funding, but adjusts existing tax credit rules for disaster recovery.
