This 25 bill relates to the solar energy system tax credit. Under 26 existing law, the Iowa solar energy system tax credit available 27 against the individual or corporate income tax, the franchise 28 tax, or the moneys and credits tax equals the sum of 50 percent 29 of the federal residential energy efficient property credit, 30 not to exceed $5,000, plus 50 percent of the federal energy 31 credit related to solar energy systems, not to exceed $20,000. 32 The bill strikes provisions basing the Iowa solar energy 33 system tax credit as a percentage of federal energy tax credits 34 and creates a new Iowa solar energy system tax credit for 35 -5- LSB 1704YH (3) 89 jm/jh 5/ 7

H.F. 221 installations completed on or after January 1, 2021, but before 1 December 31, 2030. The bill creates a residential solar energy 2 system tax credit equal to 15 percent of the gross cost of the 3 system, up to $5,000. The bill creates a separate commercial 4 solar energy system tax credit not to exceed 15 percent of the 5 gross cost of the system, up to $20,000. The tax credit is 6 available against the individual and corporate income taxes, 7 the franchise tax, and the moneys and credits tax. 8 The bill defines “residential solar energy system” to 9 mean a solar energy project on residential property or 10 multiresidential property. The bill defines “commercial 11 solar energy system” to mean a solar energy system on a 12 nonresidential property. 13 Any tax credit approved under the bill is not refundable 14 but the excess for the tax year may be credited to the tax 15 liability for the following 10 years or until depleted, 16 whichever is earlier. 17 A taxpayer eligible to claim a credit under the bill is not 18 eligible to claim a renewable energy tax credit under Code 19 chapter 476C. 20 The bill provides that a taxpayer may claim more than one tax 21 credit, but may claim only one credit per separate and distinct 22 solar energy system installation. 23 For the 2021 calendar year, the bill increases the maximum 24 cumulative value of tax credits that may be claimed during 25 the calendar year from $4 million to $17 million. Of this 26 increased maximum tax credit amount for the 2021 calendar year, 27 $7 million is reserved for claims placed on the wait list prior 28 to January 1, 2021. The reserved claims shall be approved 29 using the same priority of approval established for the wait 30 list. An applicant placed on the wait list prior to January 31 2021 shall be given priority to make a claim for amounts not 32 reserved for the year 2021, to the extent such claims have not 33 been claimed. In the event the maximum cumulative amount of 34 tax credits have been claimed for the year 2021 under the bill, 35 -6- LSB 1704YH (3) 89 jm/jh 6/ 7
