This bill proposes a temporary tax credit for the purchase and installation of solar energy systems in Minnesota. It introduces a new section that defines key terms related to solar energy systems, including "business property," "homestead," "solar energy system," and others. The bill establishes eligibility criteria for taxpayers who receive electric service from municipal utilities or cooperative electric associations and who install solar energy systems during specified timeframes. The credit percentage varies based on when the system is placed into service, starting at 15% for systems installed between January 1, 2025, and December 31, 2025, and decreasing to 11% for systems installed between January 1, 2027, and December 31, 2028. The maximum allowable credit is set at $2,500 for homestead installations and $15,000 for business properties.

Additionally, the bill stipulates that if the credit exceeds a claimant's tax liability, the excess amount will be refunded, with funds appropriated from the general fund to cover these refunds. The new section will expire on January 1, 2029, and the provisions will be effective for taxable years beginning after December 31, 2024. This initiative aims to encourage the adoption of solar energy systems by providing financial incentives to taxpayers.
