Maybe. If you are still making payments on the loan you refinanced, you will need to answer "yes" to this question. You must answer yes because you are no longer allowed to deduct the interest from a loan secured by your home that was not used to buy, build, or substantially improve your home.
In addition, for mortgages originating after 12/15/2017 that are used to buy, build or substantially improve your home, you can only deduct mortgage interest on up to $750,000 of debt.
