Home equity line of credit interest is deductible only if you use the borrowed money to buy, build, or improve your home

The IRS allows you to deduct interest on a home equity line of credit (HELOC) only under one condition: the money must go toward your home itself. If you borrowed $50,000 against your home's equity but used it to pay off credit cards, buy a car, or cover medical bills, that interest is not deductible. The use of the money matters more than the type of loan.

This rule comes from Section 163(h) of the tax code, which limits what "home acquisition debt" means. A HELOC is treated as home acquisition debt when the proceeds go directly into the property. Once the money leaves that purpose, the interest loses its deductibility, even though the loan is still secured by your home.

You report deductible HELOC interest on Schedule A (Form 1040) as part of your itemized deductions, but only if you itemize rather than take the standard deduction. Many homeowners find that their total itemized deductions—including mortgage interest, property taxes, and charitable gifts—do not exceed the standard deduction, which means they get no tax benefit from the HELOC interest anyway.

Key Takeaways

  • HELOC interest is deductible only when you use the borrowed funds to buy, build, or substantially improve your primary home or a second home.
  • If you use HELOC money for any other purpose—debt consolidation, education, medical bills, or living expenses—that interest cannot be deducted.
  • You must itemize deductions on Schedule A to claim HELOC interest; the standard deduction often makes itemizing unnecessary.
  • The total of all your itemized deductions (mortgage interest, property taxes, charitable gifts, and HELOC interest) must exceed your standard deduction for you to benefit from deducting the HELOC interest.

How the IRS determines whether your HELOC interest qualifies

The IRS tracks the purpose of the borrowed money, not the form of the loan. You can document this by keeping records of how the funds were disbursed and what they paid for. If your HELOC check went directly to a contractor for a kitchen renovation, that interest is deductible. If the same check went into your checking account and you later used it for multiple purposes, the IRS may disallow the deduction unless you can show the funds were used for home improvement.

The home must be your primary residence or a second home (such as a vacation property). A HELOC on a rental property or investment property does not may have access to under this rule; rental property interest follows different deduction rules tied to business use.

There is also a dollar limit. As of 2024, you can deduct interest only on up to $750,000 of home acquisition debt if you are married filing jointly, or $375,000 if you are married filing separately. If your HELOC balance exceeds these thresholds, only the interest on the first $750,000 (or $375,000) is deductible. Single filers and heads of household use the $750,000 limit.

The difference between home acquisition debt and home equity debt

The tax code distinguishes between two types of home-related borrowing. Home acquisition debt is money borrowed to buy, build, or improve a home. Home equity debt is any other borrowing secured by your home—such as a HELOC used to consolidate credit cards or pay for a child's education.

Before 2018, you could deduct interest on up to $100,000 of home equity debt regardless of its purpose. The Tax Cuts and Jobs Act eliminated that deduction for tax years 2018 through 2025. This means that as the law currently stands, a HELOC used for non-home purposes generates no deductible interest.

This distinction matters when you have multiple loans on your home. If you have a mortgage of $300,000 and a HELOC of $100,000, and you used the HELOC to pay for college tuition, only the mortgage interest is deductible (up to the $750,000 limit on home acquisition debt). The HELOC interest is not.

What counts as a home improvement for HELOC deduction purposes

The IRS considers a home improvement to be work that adds value to your home, prolongs its useful life, or adapts it to a new use. Replacing a roof, adding a room, installing new plumbing or electrical systems, and upgrading a kitchen or bathroom all may have access to. Painting the interior, replacing worn carpeting, and fixing a broken window also count, as long as the work is not routine maintenance.

The line between improvement and maintenance can be unclear. Replacing one broken window is maintenance; replacing all the windows in your home is an improvement. Fixing a leaky roof is maintenance; replacing the entire roof is an improvement. When in doubt, keep receipts and invoices that describe the work performed, because the IRS may ask you to justify the deduction.

Improvements to a second home (such as a vacation house or cabin) also may have access to, but improvements to a rental property do not fall under this rule. Rental property interest is deductible under different rules related to business expenses.

How to report HELOC interest on your tax return

If you have deductible HELOC interest, you report it on Schedule A (Form 1040), which is the form for itemized deductions. The line for mortgage interest and points paid includes HELOC interest that qualifies as home acquisition debt. You enter the total of all deductible home loan interest in one box.

Your lender will send you a Form 1098 (Mortgage Interest Statement) each January showing the interest you paid during the prior year. This form lists the address of the home securing the debt. If you have multiple HELOCs or mortgages, you may receive multiple 1098 forms. Add up all the deductible interest from all forms and enter the total on Schedule A.

You can only claim this deduction if your total itemized deductions exceed your standard deduction. For 2024, the standard deduction is $14,600 for single filers, $29,200 for married couples filing jointly, and $21,900 for heads of household. If your mortgage interest, property taxes, charitable gifts, and other itemized deductions add up to less than these amounts, you will take the standard deduction instead, and the HELOC interest provides no tax benefit.

When HELOC interest is definitely not deductible

HELOC interest used to pay off credit card debt, medical bills, student loans, or car loans is never deductible. The IRS does not care that the loan is secured by your home; what matters is where the money went. If you borrowed $30,000 against your home equity to consolidate credit card balances, you cannot deduct any of that interest, even though you are paying interest on a home-secured loan.

Similarly, HELOC interest used for living expenses, vacations, education, or any other non-home purpose is not deductible. Some homeowners use a HELOC as a flexible line of credit for various purposes throughout the year. If the money goes to purposes other than home acquisition, none of the interest is deductible.

If you used a HELOC for both home improvement and other purposes, you must track which portion of the borrowed funds went to each use. Only the interest on the portion used for home improvement is deductible. This requires careful record-keeping from the time you draw the funds.

Comparing HELOC interest deductions to other home-related tax benefits

A HELOC is one way to borrow against your home, but it is not the only way. A cash-out refinance (refinancing your mortgage for more than you owe and taking the difference in cash) can also generate deductible interest if you use the extra cash for home improvement. A home equity loan (a fixed-rate second mortgage) works the same way as a HELOC: interest is deductible only if the proceeds go to home acquisition.

The mortgage interest deduction itself is often more valuable than a HELOC interest deduction because mortgage debt has a higher limit ($750,000 for home acquisition debt) and is more commonly used for the home itself. If you are considering borrowing against your home, understanding which type of loan and which use will generate a deductible interest expense can affect your decision.

Keep in mind that the deduction is only valuable if you itemize. Many homeowners, especially those in lower tax brackets or those who have already paid off their mortgages, find that itemizing does not save them money compared to the standard deduction. A tax professional can help you determine whether the HELOC interest deduction is worth pursuing in your situation.

Frequently Asked Questions

Can I deduct HELOC interest if I used the money for home repairs?

Yes, if the repairs are improvements that add value to your home or extend its life. Replacing a roof, fixing structural damage, or upgrading systems qualifies. Routine maintenance like painting or fixing a single broken window may not. Keep invoices showing what work was done to support your deduction.

What if I used my HELOC for both home improvement and paying off credit cards?

You can deduct interest only on the portion of the HELOC used for home improvement. You must track which draws went to which purpose. If you cannot separate the uses, the IRS may disallow the entire deduction, so document your spending carefully from the start.

Do I have to file Schedule A to deduct HELOC interest?

Yes. HELOC interest is an itemized deduction, so you must file Schedule A instead of taking the standard deduction. If your total itemized deductions are less than the standard deduction for your filing status, you will not benefit from deducting the HELOC interest.

Is HELOC interest deductible on a vacation home or rental property?

A vacation home (second home you own) qualifies if you used the HELOC proceeds for home improvement. A rental property does not may have access to under this rule; rental property interest follows business deduction rules instead.

What if my HELOC balance is over $750,000?

You can deduct interest only on the first $750,000 of home acquisition debt (or $375,000 if married filing separately). Interest on the amount above that limit is not deductible, even if the entire HELOC was used for home improvement.
