The main purpose of this legislation, known as the Critical Businesses Preparedness Act, is to provide financial support to essential businesses in areas prone to natural disasters. Specifically, it offers a tax credit for the costs associated with installing electric generators in these high-risk disaster zones. The goal is to ensure that critical services remain operational during emergencies, such as floods or hurricanes. Key provisions of the Act include a tax credit equal to 30 percent of the expenses incurred by qualifying businesses for electric generators.
