Income tax credit; reauthorizing credit for construction of energy efficient property for certain tax years. Effective date.

SB 99 reauthorizes an income tax credit for builders constructing energy-efficient residential properties under 2,000 square feet in Oklahoma. It provides a $4,000 credit for homes certified 40%+ above energy codes or $2,000 for those 20-39% above, requiring properties to be substantially complete in the same tax year the credit is claimed. The credit applies to new construction only (not retrofits) and requires certification by an accredited provider using the Home Energy Rating System. This bill directly affects Oklahoma builders who construct qualifying energy-efficient homes, offering tax relief tied to specific efficiency standards and completion timing.
