Are HELOC Interest Payments Tax Deductible?

HELOC interest may be tax deductible — but only under specific conditions established by the Tax Cuts and Jobs Act of 2017. The rules are more nuanced than many homeowners realize, and consulting a tax advisor for your specific situation is strongly recommended.

When HELOC Interest IS Deductible

Under current tax law, interest on a HELOC is deductible when the loan proceeds are used to buy, build, or substantially improve the home that secures the HELOC. For example:

• Using a HELOC to add a room to your primary residence — deductible
• Using a HELOC to remodel your kitchen — deductible
• Using a HELOC to build an ADU on your property — potentially deductible

When HELOC Interest is NOT Deductible

Interest on HELOC funds used for non-home purposes is generally not deductible:

• Debt consolidation (paying off credit cards)
• Tuition or personal expenses
• Business investment unrelated to the property
• Purchasing another property

Loan Limit

The deductibility applies to mortgage debt (combined first mortgage + HELOC) up to $750,000 for loans originated after December 15, 2017 ($1,000,000 for prior loans). Interest on amounts above the limit is not deductible.

Important Disclaimer

Tax laws are complex and individual circumstances vary significantly. This is general information only — not tax advice. Always consult a qualified CPA or tax advisor before making decisions based on potential tax deductibility.

Questions to bring to your tax professional

This page explains the general rule; the answer for your return depends on facts only a tax professional can review. Walking in with specifics makes that conversation shorter and more useful.

• What did I spend the HELOC draws on, and when?
• Is the home that secures the line a qualifying residence for my situation?
• How do my total mortgage balances compare with the limits mentioned above?
• Does itemizing make sense for me this year, or does the standard deduction come out ahead?

Splitting one draw across several uses (illustrative example)

Imagine a $100,000 draw: $60,000 goes to a kitchen and bath remodel and $40,000 pays off credit cards. Many borrowers assume the whole $100,000 is treated the same way. A tax professional would typically look at the portion tied to improving the home separately from the portion used for other purposes, so 60% of the balance might be analyzed one way and 40% another. The split is also why keeping clean records matters.

Records worth keeping

• Contractor contracts, invoices and proof of payment for improvements.
• HELOC statements showing each draw date and amount.
• Your annual interest statement from the lender, which reports interest paid but does not tell you how the money was used.
• If practical, deposit improvement funds into a dedicated account so the trail is easy to follow.

Common mistakes

Borrowers often assume the lender’s year-end form settles the question, mix improvement spending with personal spending in one account, or forget that tax rules can change. Lendia is a mortgage brokerage and cannot give tax advice.

Frequently asked questions

Does Lendia tell me whether my interest is deductible?

No. We can show you how the loan works and what you will pay, but deductibility is a tax question for a CPA or tax professional.

Does it matter when I took the draw?

It can. Rules have referenced when the debt was originated and how the money was used, so note your draw dates and ask your tax professional how they apply.

What if I use the line for a mix of repairs and personal bills?

Keep the spending documented by category. A tax professional can then decide how to treat each part instead of guessing from a single balance.
