H.F. 323 available against the individual or corporate income tax, the 1 franchise tax, or the moneys and credits tax equals the sum of 2 50 percent of the federal residential energy efficient property 3 credit, not to exceed $5,000, plus 50 percent of the federal 4 energy credit related to solar energy systems, not to exceed 5 $20,000. 6 The bill maintains the existing framework of the solar 7 energy system tax credit as a percentage of the federal energy 8 credit but creates a new Iowa solar energy system tax credit 9 for installations completed on or after January 1, 2021. For 10 solar energy systems completed on or after January 1, 2021, the 11 bill allows a taxpayer to calculate the solar energy system tax 12 credit amount as a percentage of the federal energy credit or 13 calculate the solar energy system tax credit amount pursuant 14 to the new Iowa solar energy system tax credit created in the 15 bill. The bill creates a residential solar energy system tax 16 credit equal to 15 percent of the gross cost of the system, up 17 to $5,000. The bill creates a separate commercial solar energy 18 system tax credit not to exceed 15 percent of the gross cost of 19 the system, up to $20,000. The bill defines “residential solar 20 energy system” to mean a solar energy project on residential 21 property or multiresidential property. The bill defines 22 “commercial solar energy system” to mean a solar energy system 23 on a property that is not residential or multiresidential. 24 Any tax credit approved under the bill is not refundable 25 but the excess for the tax year may be credited to the tax 26 liability for the following 10 years or until depleted, 27 whichever is earlier. 28 The tax credit is available against the individual and 29 corporate income taxes, the franchise tax, and the moneys and 30 credits tax. 31 A taxpayer eligible to claim a credit under the bill is not 32 eligible to claim a renewable energy tax credit under Code 33 chapter 476C. 34 The bill provides that a taxpayer may claim more than one tax 35 -5- LSB 2067YH (2) 89 jm/jh 5/ 6

H.F. 323 credit, but may claim only one credit per separate and distinct 1 solar energy system installation. 2 The bill permanently increases the maximum cumulative value 3 of tax credits that may be claimed during the year from $4 4 million to $10 million. 5 The bill eliminates the wait list for the tax credit by 6 removing the maximum cumulative value of tax credits that may 7 be claimed in a year for calendar year 2021 until the wait list 8 is eliminated. If the wait list is eliminated during calendar 9 year 2021, the maximum cumulative value of tax credits that 10 may be claimed during calendar year 2021 shall not exceed the 11 maximum cumulative value established in the bill, $10 million. 12 The bill takes effect upon enactment and applies 13 retroactively to January 1, 2021, for tax years ending on or 14 after that date. 15 -6- LSB 2067YH (2) 89 jm/jh 6/ 6
