Home equity loan interest is deductible only if you use the money to build, improve, or substantially repair your home

The IRS allows you to deduct interest on a home equity loan, but only under one condition: the borrowed money must go toward your home itself. If you take out a home equity loan and use it to pay credit card debt, buy a car, or cover medical bills, that interest is not deductible. The distinction matters because it determines whether you can claim the deduction on Schedule A when you itemize.

Home equity loans are secured by your house as collateral, which is why the IRS treats them differently from unsecured debt. But the tax code does not care that your loan is secured—it cares what you did with the money. A $50,000 home equity loan used to renovate your kitchen qualifies. The same $50,000 used to pay off student loans does not, even though both are legitimate reasons to borrow.

You must also meet a second requirement: your total mortgage debt (including the home equity loan) cannot exceed the fair market value of your home. Most homeowners with standard mortgages and reasonable home equity loans clear this threshold automatically, but it becomes relevant if you have multiple loans or if your home's value has dropped.

Key Takeaways

  • Home equity loan interest is deductible only when the borrowed funds are used to build, improve, or substantially repair your primary residence or a second home you own.
  • If you use a home equity loan for any other purpose—debt consolidation, education, medical expenses, or a vehicle—the interest is not deductible regardless of the loan terms.
  • Your total mortgage debt (first mortgage plus home equity loans) cannot exceed the fair market value of your home for the interest to may have access to for deduction.
  • You must itemize deductions on Schedule A to claim home equity loan interest; the standard deduction is often larger and eliminates the need to track mortgage interest.

What counts as a may have access to home improvement

The IRS defines a may have access to use narrowly. The money must go toward building, improving, or substantially repairing your home. This includes additions (a new bedroom or bathroom), renovations (a kitchen remodel), structural repairs (foundation work, roof replacement), and permanent fixtures (new HVAC system, solar panels, new windows). The improvement must add value to the home or prolong its useful life.

Routine maintenance does not count. Painting, landscaping, replacing worn-out appliances with the same model, or fixing a broken window does not may have access to as an improvement. The line is not always obvious—replacing a roof with a better one might may have access to, but replacing it with an identical one might not. When in doubt, keep receipts and documentation showing what work was done and why it was necessary.

Refinancing an existing home equity loan does not change the deductibility of the interest. If the original loan was used for home improvements, the interest on the refinanced loan remains deductible. But if you refinance and pull out additional cash for non-home purposes, only the interest on the portion used for home improvements is deductible.

The difference between a home equity loan and a HELOC

A home equity loan is a lump sum you borrow all at once, with a fixed interest rate and a set repayment schedule. A home equity line of credit (HELOC) is a revolving credit line—you draw what you need, when you need it, and pay interest only on what you use. Both are secured by your home, and both follow the same tax rules: interest is deductible only if the money goes toward home improvements.

The practical difference for taxes is tracking. With a home equity loan, you know exactly how much you borrowed and what it was used for. With a HELOC, you may draw money over time for different purposes. If you use part of your HELOC for a kitchen remodel and part for a vacation, only the interest on the kitchen portion is deductible. You will need to track which draws went to which purpose and calculate the interest accordingly.

Income limits and the $750,000 debt cap

There is no income limit for deducting home equity loan interest. High earners and low earners are treated the same. However, there is a debt limit: your total mortgage debt cannot exceed $750,000 (or $375,000 if you are married filing separately). This limit applies to the combined balance of your first mortgage, second mortgage, home equity loans, and HELOCs.

If your total debt exceeds $750,000, only the interest on the first $750,000 is deductible. For example, if you have a $600,000 first mortgage and a $200,000 home equity loan, your total is $800,000. Only $750,000 of that debt qualifies, so you can deduct interest only on $750,000 of the balance. Your lender will not calculate this for you—you will need to do it yourself or work with a tax preparer.

This limit has been in place since 2018 and is set to expire after 2025 unless Congress extends it. Check current tax law or speak with a tax professional to confirm the limit in the year you are filing.

Itemizing versus the standard deduction

To claim home equity loan interest, you must itemize deductions on Schedule A of your tax return. You cannot claim it if you take the standard deduction. For 2024, the standard deduction is $14,600 for single filers and $29,200 for married couples filing jointly. If your total itemized deductions (mortgage interest, property taxes, charitable donations, and other may be able to access expenses) do not exceed the standard deduction, you will not benefit from deducting home equity loan interest.

Many homeowners find that the standard deduction is larger than their itemized deductions, especially after the 2018 tax law changes. This means that even though your home equity loan interest is technically deductible, you may not actually claim it because itemizing does not save you money. A tax preparer can calculate both scenarios and tell you which approach reduces your tax bill.

If you are on the borderline—your itemized deductions are close to the standard deduction—the home equity loan interest might be the difference that makes itemizing worthwhile. But if you are well below the standard deduction, the interest deduction will not help you.

Documentation you need to keep

The IRS does not require you to attach receipts to your tax return, but you must be able to produce them if audited. Keep the loan documents showing the loan amount and terms, bank statements showing the funds were disbursed, and invoices or receipts from the contractor or vendor showing what work was done. If you did the work yourself, keep records of materials purchased and dates of work.

For a HELOC, keep statements showing which draws were made and when, along with documentation of what each draw was used for. If you used the line of credit for multiple purposes, you will need to show the breakdown. A simple spreadsheet tracking each draw and its purpose is sufficient.

Keep these records for at least three years after you file your return, and longer if the IRS contacts you. If you claim a large deduction or have a complex situation, consider keeping records for seven years.

What happens if you use the money for something else later

The deductibility of home equity loan interest is determined by what you do with the money when you borrow it, not what you do with it later. If you borrow $50,000 for a home renovation and then later use some of that money for a different purpose, the interest remains deductible. The IRS looks at the original intent, not the subsequent use.

However, if you refinance the loan and pull out additional cash for non-home purposes, only the interest on the original amount is deductible. The interest on the new cash-out portion is not deductible. This is why it matters to keep the loan documents and track what each loan was for.

Frequently Asked Questions

Can I deduct home equity loan interest if I used the money to pay off credit card debt?

No. The IRS does not allow a deduction for interest on a home equity loan used for debt consolidation, regardless of what the original credit card debt was for. The deduction depends on how you use the borrowed money, not on the purpose of the debt you are paying off.

What if I used my home equity loan for both a kitchen remodel and a car purchase?

Only the interest on the portion used for the kitchen remodel is deductible. You will need to track how much of the loan went to each purpose and calculate the interest proportionally. If $30,000 of a $50,000 loan went to the kitchen, 60 percent of the interest is deductible.

Do I have to deduct home equity loan interest, or can I choose not to?

You do not have to claim the deduction. If itemizing does not save you money compared to the standard deduction, you would not claim it. But there is no penalty for not claiming a deduction you are may have access to to—you simply would not benefit from it.

Is home equity loan interest deductible on a second home or vacation home?

Yes, if the money is used to build, improve, or substantially repair a second home you own. The rules are the same as for your primary residence. The home must be one you own; it cannot be a rental property or a home you are buying.

What if my home's value dropped below my mortgage debt?

If your total mortgage debt exceeds the fair market value of your home, the excess interest is not deductible. For example, if your home is worth $300,000 but you owe $350,000 in mortgages, only the interest on $300,000 is deductible. You will need to calculate the proportion and claim only that portion.
