Reminder: May 1st is the deadline to file your Iowa Tax Credit Application for 2020 geothermal installations.
There are a number of incentives available when investing in an energy efficient geothermal heating and cooling system. Federal Geothermal Tax Credits are offered for residential and commercial installations. The Iowa Geothermal Heat Pump Tax Credit and Iowa Property Tax Exemption programs are available to Iowans for Iowa residential property installations. Many Iowa utilities also have geothermal rebate programs.
Iowa Residential Geothermal Incentives
The Iowa Geothermal Heat Pump tax credit is available for Iowa residential property installations. The Iowa Geothermal Property Tax Exemption is for the assessed value added to a residential property for qualified geothermal heating or cooling system installation. Many Iowa utilities provide geothermal incentives to customers. Be sure to check with your energy provider before installing your system as some require pre-approval to be eligible for their rebate.
Iowa Geothermal Tax Credit
The current Iowa Geothermal Heat Pump tax credit was approved by the 2019 Legislature and replaces the previous program that ended December 31, 2018. The Iowa Geothermal Association, along with other industry organizations, worked diligently to inform legislators about the importance of the Iowa Geothermal Tax Credit and to get it reinstated.
The Iowa Geothermal Tax Credit is:
- Effectively a 5.2 percent credit (based on a formula of 20% of the federal residential energy efficient property tax credit which is 26% for tax years 2020 through 2022).
- For geothermal heat pump units installed on or after January 1, 2019.
- Available to the resident/owner of an Iowa residence who installs geothermal at that residence.
About the program
The current program and process is for tax year 2019 and later. Information and links are on Iowa Geothermal Heat Pump Tax Credit page of the Iowa Department of Revenue website. Check the Iowa Department of Revenue website for most current updates.
- Before claiming the tax credit for tax year 2019 or later, taxpayers must apply and receive approval for the credit with the Iowa Department of Revenue. Claims made on the Iowa 1040 without such award will be denied.
- Application deadline is May 1 following the year of installation. For example, to receive the credit for 2020 installations, the application must be received before May 1, 2021.
- The total awards are capped at $1 million annually and a waitlist will be established when the annual cap is reached.
- The credit is awarded on a first-come first-served basis.
- Application approvals are contingent upon the availability of tax credits for any particular year.

Federal Residential Geothermal Tax Credits
In late December 2020, the tax credit for geothermal heat pump installations was extended through 2023. Property is usually considered to be placed in service when installation is complete, and equipment is ready for use. However, if the system is part of the construction or renovation of a house, it is considered placed in service when the taxpayer takes residence in the house. The credit of 26% is for installations in 2020 through 2022. This credit will drop to 22% in 2023 before expiring altogether on January 1, 2024.
- 26% of total system cost in 2020 through 2022
- 22% of total system cost in 2023
- No limit to credit amount
- Can be used to offset AMT tax
- Can be used in more than one year
- Can be combined with solar and wind tax credits
- Can be combined with energy efficiency upgrade credits

Federal Commercial Geothermal Tax Credits
The Federal Commercial Geothermal Tax Credit was extended in legislation enacted in late-December 2020. The 10 percent credit is extended through 2023. The new law also makes the Section 179D Energy Efficient Commercial Buildings Deduction permanent and indexed to inflation.
Iowa Geothermal Property Tax Exemption
The Iowa Geothermal Property Tax Exemption is for the value added by any new or refitted construction or installation of a geothermal heating or cooling system on residential property. Unlike other exemptions, it does not have to be applied for in the year it was first added. The exemption runs for 10 years after it is applied for. Signup deadline is February 1.

All offer information for the states on energy tax credits, rebates and savings but information filters provided at http://energy.gov/savings make it easy to sort by type. Just select “Geothermal Heat Pumps” for any state or select “All” for a listing of every state that has some sort of financial assistance for geothermal heat pump installations.
