what percentage of the full amount for repacing windows do I use when filing income tax and what form do I use

Question

What form do I use for income tax for windows and installation to weather proof it?

Answer 1

If this is your personal residence there is no deduction for the windows. You add their cost to the basis for the house which will reduce the gain when you sell.

If you took out a home equity loan to pay for them, the interest on the loan may be deductible.
