Are HELOC Interest Tax Deductions Allowed for Debt Payoff?

When you open a home equity line of credit (HELOC), you typically access funds during a draw period, then repay what you borrow over time. You can use home equity in a variety of ways, such as to consolidate debt, buy a car, or make home improvements. Your home serves as collateral for the loan, which may make the interest deductible.

However, under current tax law, you can deduct interest only when you use the borrowed funds to buy, build, or substantially improve the home securing the loan. Among other requirements, to claim a deduction for HELOC interest, your total mortgage debt must stay within specific limits.

If you need guidance about deducting HELOC interest for debt payoff, contact a tax advisor or an experienced debtor and creditor attorney in your area.

HELOC Interest Deductibility After the TCJA

Under current rules established by the Tax Cuts and Jobs Act of 2017 (and extended by the One Big Beautiful Bill Act of 2025), HELOC interest may be deductible, but only when specific conditions are met.

Tax Years Beginning After 2017

For tax years beginning after 2017, the rules are as follows. If home equity loans or lines of credit are secured by your main home or second home and are used to buy, build, or substantially improve the home that secures your loan, the interest you pay on the borrowed funds is classified as home acquisition debt. In such cases, the interest 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.

This means that HELOC interest is tax-deductible if the funds were used to buy, build, or substantially improve the home that secures your loan, but not interest on debt used for purposes unrelated to the home, such as paying off credit cards or paying for a vacation.

A HELOC secured by an investment property does not qualify for the qualified-residence mortgage interest deduction, although its interest may be deductible under other rules, depending on how the proceeds are used.

Tax Years Before 2018

For tax years before 2018, HELOC interest may be deductible regardless of how the funds were used, subject to certain dollar limitations.

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.

HELOC Tax Deduction Rules

You can claim the qualified-residence mortgage interest deduction for HELOC interest only if you use the funds to buy, build, or substantially improve the qualified residence securing the loan.

You cannot, however, deduct HELOC interest for debt consolidation or personal expenses. Interest on funds used for debt consolidation or personal purchases is not tax-deductible.

Limits for the Home Mortgage Interest Deduction

Even when the funds are used for qualifying improvements, the home equity loan interest you can deduct is subject to strict limits.

Under 26 U.S.C. § 163(h)(3), the deduction generally applies to up to $750,000 of qualified home acquisition debt for most taxpayers, or $375,000 for married taxpayers filing separately.

The cap generally applies to combined qualifying debt, including a primary mortgage and a qualifying HELOC balance, but qualifying debt incurred on or before December 15, 2017 may be subject to higher grandfathered limits.

How HELOC Funds Are Used

Under the permanent OBBBA guidelines, deductibility depends on how you use the funds. You must use the funds for “capital improvements.”

Under IRS rules, the improvements must add value to your home, prolong its useful life, or adapt it to new uses. No deduction is allowed for interest on funds you used to make minor repairs to your home or to pay for medical bills or vacations.

How To Claim the HELOC Interest Deduction

To deduct HELOC interest, you must first meet the foundational requirement: the borrowed funds must have been used to buy, build, or substantially improve the home that secures the loan. This use-of-funds rule is the core requirement. Confirm that it applies to your situation.

Only taxpayers who itemize deductions can claim a HELOC interest deduction. Deductions are itemized on Schedule A (Form 1040). In general, itemizing only makes sense if your total deductions are higher than the standard deduction.

The IRS sets standard deduction amounts for various groups of taxpayers, including:

• Single
• Married filing jointly
• Married filing separately
• Head of household
• Qualifying surviving spouse

These amounts change every year, so check IRS.gov for the current figures for the tax year you would like to claim the deduction.

How To Confirm Eligibility

Add up your itemized deductions, including your qualifying HELOC interest. Compare that total to the applicable standard deduction.

If your itemized total is higher, itemizing is the better choice. Gather your documentation, review your Mortgage Interest Statement (Form 1098), and any other proof of additional interest paid.

Documenting Your Deduction

You must document how you spent the funds. This documentation can include invoices and receipts that show how much you spent on capital improvements. Then, calculate and itemize deductions, and file on Schedule A (Form 1040).

Tax rules can be complicated, and every situation is different. A qualified tax professional can help you confirm eligibility, whether claiming the deduction is right for you, and provide other guidance for accurate filing.

Mistakes That Could Affect Your Deduction

It’s essential to be mindful of common mistakes that could impact your ability to claim HELOC interest, including:

• Losing track of required documentation. Keep receipts and invoices showing how you used the HELOC funds.
• Mixing personal and home use. Only funds used to buy, build, or substantially improve your home qualify for the deduction. If you use HELOC funds for a bathroom remodel and a vacation, only the funds used for the bathroom remodel would qualify.
• Using funds to consolidate debt. Consolidating debt from high-interest credit cards into a lower-interest HELOC doesn’t qualify for a tax deduction.
• Exceeding the debt limits. You may have mortgage debt above the applicable limit, but you can deduct interest only to the extent allowed for qualified home acquisition debt. The limit generally applies to the outstanding principal of your first mortgage and qualifying home equity loan or line of credit, not to the interest itself.

Accurate, well-documented filings are critical for substantiating legitimate deductions.

Legal Risks of Improperly Claiming the Deduction

The taxpayer bears the burden of proof for a HELOC tax deduction. As with any deduction, the IRS can disallow deductions that lack proper support. Improperly claiming the deduction can lead to the following:

• Back taxes owed
• Accuracy-related penalties (commonly 20% of the underpayment)
• Interest charges on unpaid taxes
• Fraud penalties, when warranted

Claiming a deduction that cannot be substantiated carries risk. Always carefully review the supporting documents before filing your tax return. Any gains are only modest, but penalties and interest can be very costly. Understanding debtor and creditor rights in this context is essential.

Contact an Attorney To Get Help

To deduct HELOC interest, it must meet the buy, build, or substantially improve your home rule. Thus, the IRS does not allow you to claim a deduction for interest on credit card debt using a HELOC. If you have questions about your HELOC, contact an experienced debtor and creditor rights attorney in your area.
