Idaho Alternative Energy Device Deduction

Article ID: 60050 Email Print
How much can I claim for my Idaho alternative energy device deduction?



 If you install an alternative energy device in your Idaho residence, you can deduct a portion of the amount actually paid or accrued (billed but not paid).

In the year the device is placed in service, you can deduct 40% of the cost to construct, reconstruct, remodel, install, or acquire the device, but not more than $5,000.

In the next three years after installation, you can deduct 20% of these costs per year, but not more than $5,000 in any year.

Qualifying devices include:


􀁸 A system using solar radiation, wind, or geothermal resource primarily to provide heating or cooling, or produce electrical power, or any combination thereof


􀁸 A fluid-to-air heat pump operating on a fluid reservoir heated by solar radiation or geothermal resource, but not an air-to-air heat pump unless it uses geothermal resources as part of the system


􀁸 A natural gas or propane heating unit that replaces a noncertified wood stove


􀁸 An Environmental Protection Agency (EPA) certified wood stove or pellet stove meeting the most current industry and state standards that replaces a noncertified wood stove


A noncertified wood stove is a wood stove that doesn't meet the most current EPA standards. The noncertified wood stove must be taken to a site authorized by the Division of Environmental Quality (DEQ) within 30 days from the date of purchase of the qualifying device. 

The natural gas or propane heating unit, the EPA-certified wood stove, or pellet stove must be installed the same tax year that the nonqualifying wood stove is turned in to the DEQ.

This particular deduction is claimed on the Idaho Supplemental Schedule, Form 39R, and you can contact the Idaho State Tax Commission at for more details.
