Income tax; limiting credit allowance for zero-emission facilities to certain tax years; limiting carry forward of credit. Effective date.

SB 239 modifies Oklahoma's tax credit for electricity generated by zero-emission facilities (like wind, solar, hydro, or geothermal power plants). It limits the credit to tax years ending by 2025, ending the ability to carry forward unused credits beyond that year. For credits claimed after July 2019, taxpayers must choose between receiving an 85% direct refund or carrying the credit forward for up to 10 years (ending in 2025). This bill directly affects businesses and entities generating eligible renewable electricity in Oklahoma, altering how they can use or access these tax credits.
