Please speak with your accountant if you have questions about what types of home improvements qualify.IRS publication 936 explains how the home mortgage interest deduction works.

Those expenses are non-deductible from the get-go.To mitigate the loss of deduction, you can ask your employer to start picking up the cost or have them reimburse you under an accountable plan.
