State tax filing

No, Iowa doesn’t have a deduction for installing energy efficient cooling and heating systems.  The state does have some energy efficiency credits available, including

  • Solar Energy System Tax Credit,
  • Geothermal Heat Pump Tax Credit, and 
  • Renewable energy tax credit,

but these wouldn’t appear to apply for the system you’ve installed.

However, please see the 2021 Expanded Instructions and IA 148 Iowa Tax Credits Schedule Instructions, found at State of Iowa Tax Forms, to view the requirements.
