Legislation Enacts Energy Efficiency Upgrade Deduction for Existing Residences

Idaho enacted legislation (H.B. 485) replacing the insulation deduction for existing residences with a deduction for energy efficiency upgrades.

Energy efficiency upgrades are improvements to the building envelope or duct system of an existing residence, which meet or exceed certain international energy conservation code standards in place in Idaho during the taxable year the improvements are made.

Upgrades include additional insulation, replacement windows, storm windows, weather stripping and caulking, and duct sealing.

The legislation, enacted April 3, amends existing law and is retroactively effective to Jan. 1.
