Is home equity line of credit (HELOC) interest tax deductible?

Woman at a table researching whether HELOC interest is tax deductible.

Please note: Discover® Home Loans offers a home equity loan product but does not offer HELOCs.

The interest on a HELOC could be tax deductible in some circumstances.

According to the IRS, you may be able to deduct the interest on a HELOC secured by your main or second home, subject to certain dollar limitations. However, you must use the borrowed funds to "buy, build, or substantially improve" the residence. These rules are for tax years 2018 through 2025 and will change in 2026.

Before signing any paperwork, make sure you understand the tax implications of a HELOC. Consult a tax advisor for more information based on your specific circumstances.

HELOC tax deductions: What to know

The following rules are for tax years 2018 through 2025:

  • The interest on borrowed funds from a HELOC may be tax deductible, but there are restrictions on how the HELOC can be used in order to qualify for the deduction.
  • If you use funds from a HELOC to buy, build, or substantially improve the residence that secured the loan, the interest you pay may be tax deductible. However, if you use the loan for other purposes — for example, paying credit card debts — the interest is not tax deductible.
  • If you qualify for and want to claim this deduction, you can't take the standard deduction. Instead, you must itemize the HELOC interest tax deduction and other eligible deductions on Schedule A (IRS Form 1040), line 8a.

Consult a tax advisor to learn more about HELOC tax deductions.

When is HELOC interest tax deductible?

The interest you pay on borrowed funds from a HELOC may be tax deductible (up to certain dollar limitations) if you use the HELOC to buy, build, or substantially improve the residence that secured the loan. The interest may only be tax deductible if paid on the portion of the loan that's used for these purposes.

Say you take out a $10,000 HELOC and use $5,000 of it to pay off credit card debt and $5,000 to substantially improve your home. You may only be able to deduct the interest on the $5,000 used to substantially improve your home.

The IRS says that a home improvement is "substantial" if it adds to the value of your home, prolongs your home's useful life, or adapts it to new uses. For example, repairs that maintain your home, such as repainting, aren't considered substantial improvements. However, painting as part of a renovation that significantly enhances your home may be considered a substantial improvement. 

Consult a tax advisor to learn more about which home improvements are considered substantial.

How to claim a HELOC tax deduction

First, you need an IRS Form 1098 (Mortgage Interest Statement) from your lender. This form lists the amount of interest you paid on your HELOC in the previous year. It's a good idea to keep documentation showing how you used your HELOC loan funds, such as receipts and invoices, in case the IRS ever asks for it.

If eligible, you can deduct the interest you paid on your HELOC by itemizing it alongside any other deductions on Schedule A (IRS Form 1040), line 8a.

If you have any questions, speak with a tax professional.

Other advantages of HELOCs

Depending on your circumstances, HELOCs may offer several advantages over other loans.  Unlike loans disbursed in a lump sum, a HELOC allows borrowers to access funds as needed, which may make it a convenient option for unexpected expenses or emergencies.

Also, you may use HELOCs for various purposes, such as home improvements, debt consolidation, or property investment. 

Home equity loans vs HELOCs

Home equity loans and HELOCs are both ways to borrow money against the value of your home. However, there are some key differences between the two. 

A home equity loan provides a lump sum of money, typically with a fixed interest rate.

A HELOC, on the other hand, allows you to borrow money as needed up to a predetermined limit during the initial phase of the loan, which is called the “draw period.” The interest rate on a HELOC is usually variable, and you may only be required to pay interest during the draw period. After that, you normally enter a repayment period where you pay interest and the loan principal.

Both loans can be helpful in different situations. For example, a home equity loan may be the better option if you need a large sum of money all at once. A HELOC may be best if you need ongoing access to funds over a longer period.

Whether you have a home equity loan or a HELOC, interest may be tax deductible if the loan meets certain requirements.

Are HELOCs and home equity loans beneficial without a tax deduction?

There are still situations where a HELOC may be a smart financial move, even without a tax deduction. Suppose you want to refinance high-interest debts. In this case, a HELOC with a low interest rate may save you money, even if you don't get a tax benefit from deducting the interest.

Just keep in mind that if your home secures a HELOC and you fall behind on your payments, you may end up in foreclosure. Review your needs and ability to repay the loan if you’re considering taking out a HELOC.

HELOC interest tax deduction FAQs 

Here are some FAQs about the HELOC interest tax deduction:

Is a HELOC interest tax deduction a good idea?

The answer to this depends on your personal financial situation. To claim the deduction, you must itemize deductions on your tax return rather than take the standard deduction. If the standard deduction is higher than your itemized deductions, it may not make financial sense to go down this route. 

Consider seeking advice from a tax professional who can help determine what may work best for you.

How much HELOC interest is tax deductible?

The IRS considers a HELOC a type of home mortgage, and there are dollar limitations on how much home mortgage interest you can deduct on your tax return. 

For 2024 returns, you may be able to deduct interest on the first $750,000 of "indebtedness" when filing single/married filing jointly or the first $375,000 when married filing separately. Indebtedness is the total amount of debt you owe that is secured by your home, which may include a primary mortgage, second mortgage, and other secured loans. 

Higher limitations exist if you're deducting mortgage interest from indebtedness that incurred before December 16, 2017: $1 million when filing single/married filing jointly or $500,000 when married filing separately. 

Can HELOC interest rates change?

A HELOC typically has a variable interest rate, meaning the interest rate can change over time. If a variable interest rate doesn't work for your needs, you may want to consider a home equity loan, which typically has a fixed interest rate.

Can I deduct HELOC interest if I use borrowed funds for any purpose?

Current IRS rules state that you can only deduct interest on borrowed funds from a HELOC if you use those funds to buy, build, or substantially improve the home that secured the loan. That means you can't deduct interest if you use funds to pay debt, take a vacation, or do anything else.

Do I need to pay income taxes on the money I borrow from my HELOC? 

Funds received from HELOCs are not considered taxable income by the IRS. Therefore, you should not need to pay income taxes on the amount you borrow.

Closing thoughts: Is HELOC interest tax deductible?

The answer is: it depends.

According to the IRS, the interest paid on borrowed funds from a HELOC secured by your first or second home may be tax deductible if you use the funds to buy, build, or substantially improve the residence. However, the interest is not tax deductible if you use the HELOC for other purposes, such as paying debt.

Before committing to a HELOC, talk to a tax advisor or accountant to see if you qualify for this deduction. They can also help you navigate other factors when considering a HELOC, including closing costs and the difference between variable and fixed interest rates.

If you’ve already decided that a HELOC isn’t right for you, consider exploring alternative borrowing options from Discover Home Loans. You may be eligible for a home equity loan with a credit score of at least 680 and a combined loan-to-value (CLTV) ratio of up to 90%.
