The federal tax code states that I get “A credit of 30 percent of the expenditures made by a taxpayer during the taxable year for qualified geothermal heat pumps”. The Iowa state tax code states “A geothermal heat pump tax credit is available for Individual income tax equal to 20% of the federal residential energy efficient property tax credit allowed for geothermal heat pumps provided in section 25D(a)(5) of the Internal Revenue Code for residential property located in Iowa”.
Question: If my total expenditures for the heat pump is $30,000. The federal tax credit is $30000 X .3=$9000. Is the Iowa state credit @20% of the $30,000 (total expenditures) or 20% of $9000 (just the fed allowed credit)?
It is 20% of the Federal Tax Credit or in your example, 20% of the $9,000 or $1,800 IA credit or the state tax credit is equal to 6% of the system cost ($30,000 * 6% = $1,800).
Per http://www.geothermalgenius.org/states/iowa/ IOWA AND GEOTHERMAL: Geothermal heating and cooling is a proven and reliable method of delivering energy efficient, environmentally friendly heating and cooling to Iowa homes by using the earth's constant ground temperature to provide heating, cooling and hot water in both new and retrofit construction. There is a 30% Federal Tax Credit AND a 20% Iowa State Tax Credit, not a bad incentive!
