Idaho Insulation Tax Deduction
If your home was built before 1976, you can deduct the cost of adding insulation to your home in the year the insulation was installed. Replacement of the insulation is not eligible for the deduction.
Insulation materials include fiberglass, cellulose, polystyrene, and polyisocyanurate. Other materials include mastic, caulk, double pane windows, storm doors and storm windows. Labor costs are also deductible.
If for example, you have single pane windows, double pane windows are eligible for the deduction. Also, if you have double pane windows with a steel or aluminum frame you can deduct the cost to install Energy Star rated, vinyl windows.
The deductions are claimed on the Idaho Supplemental Schedule, Form 39R. Contact the Idaho State Tax Commission for additional details.
