It depends.

For tax years 2018 through 2025, if home equity loans or lines of credit secured by your main home or second home are used to buy, build, or substantially improve the residence, interest you pay on the borrowed funds is classified as home acquisition debt and may be deductible, subject to certain dollar limitations. However, interest on the same debt used to pay personal living expenses, such as credit card debts, is not deductible.

For tax years before 2018 and after 2025, for home equity loans or lines of credit secured by your main home or second home, interest you pay on the borrowed funds may be deductible, subject to certain dollar limitations, regardless of how you use the loan proceeds. For example, if you use a home equity loan or a line of credit to pay personal living expenses, such as credit card debts, you may be able to deduct the interest paid.
