Summary

Interest paid on home equity loans and HELOCs may be tax-deductible, but only if the borrowed money is used to buy, build, or substantially improve the home that secures the loan. Understanding IRS rules and deduction limits is key to knowing what you can claim and how to do so properly. The Tax Cuts and Jobs Act of 2017 imposed stricter requirements, which are set to expire in 2025. Until then, homeowners must itemize their deductions and use the loan funds specifically for home improvements to qualify for this benefit.

🏠 Home Equity Loan and HELOC Interest Deduction Rules

Whether you're tapping into a home equity loan or a home equity line of credit (HELOC), the IRS holds both to the same standards for interest deductibility. Through 2025, the interest on these products is deductible only if the borrowed money is used to "buy, build, or substantially improve" the home securing the loan. That means you can’t claim this deduction if the funds were spent on personal expenses like education, vacations, or a new vehicle. The deduction applies solely to interest paid on qualified mortgage debt secured by your property, and homeowners must itemize their deductions to take advantage of it. This policy stems from the Tax Cuts and Jobs Act of 2017, which narrowed previous guidelines that once allowed deductions for any use of the funds. The act is set to expire in 2025, after which broader deductions could return. Until then, it’s important to plan carefully and keep thorough records if you intend to deduct home equity interest.

Takeaways:

• Home equity loan and HELOC interest is deductible only if used for home improvement.

• You must itemize deductions rather than take the standard deduction to claim this benefit.

• The Tax Cuts and Jobs Act limits are in effect through 2025.

Key Terms

• Home Equity Loan: A lump-sum loan with a fixed interest rate secured by your home.

• HELOC: A revolving line of credit with a variable interest rate secured by your home.

• Itemized Deduction: A method of filing taxes where you list individual deductible expenses, including mortgage interest.

• Tax Cuts and Jobs Act (TCJA): A 2017 law that changed deduction eligibility for home equity interest.

📉 Deduction Limits and IRS Guidelines

The amount of mortgage debt on which you can deduct interest depends on when the loan was taken out. For loans originated after December 15, 2017, interest is deductible on up to $750,000 of mortgage debt, or $375,000 for married individuals filing separately. For loans between October 14, 1987, and December 15, 2017, the cap is $1 million ($500,000 for separate filers). And if your mortgage originated before October 13, 1987, you may be able to deduct all of your interest. These rules apply to the combined amount of debt secured by your home, including your main mortgage and any home equity loans or HELOCs. It’s crucial to maintain documentation on how borrowed funds are used in order to support your tax deduction claim. If unsure, a tax advisor or IRS assistance can help determine eligibility.

Takeaways:

• Deduction limits depend on when the mortgage was originated.

• The current cap for most homeowners is $750,000 in total mortgage debt.

• Pre-1987 mortgages may be eligible for full interest deduction.

Key Terms

• Mortgage Interest Deduction Limit: The maximum amount of mortgage-related debt eligible for interest deduction.

• Combined Mortgage Debt: Total of primary mortgage and any home equity loans or HELOCs secured by the home.

🧾 Itemizing vs. Standard Deduction and Tax Forms

To deduct interest paid on a home equity loan or HELOC, you must itemize your deductions using IRS Form 1040 and skip the standard deduction. This only makes sense if the total of your itemized deductions, including mortgage interest, property taxes, and charitable donations, exceeds the standard deduction for your filing status. For the 2024 tax year (filed in 2025), the standard deductions are: $29,200 for joint filers, $14,600 for single filers or married filing separately, and $21,900 for heads of household. Before filing, you should receive IRS Form 1098 from your lender showing how much interest you paid during the year. This document is critical if you intend to claim the deduction, so be sure to follow up with your lender if you haven’t received it or need help understanding it.

Takeaways:

• You must itemize to claim a home equity interest deduction.

• Compare your itemized total to the standard deduction to decide which is better.

• IRS Form 1098 reports how much mortgage interest you paid.

Key Terms

• Standard Deduction: A fixed amount you can deduct from your income without itemizing.

• Form 1098: The IRS form that shows the interest you paid on mortgages and home equity loans.

• Form 1040: The primary form for individual income tax returns, used when itemizing deductions.

Conclusion

If you’re using your home equity to fund improvements on your property, you may qualify for a valuable tax deduction on the interest paid — but only if you follow the IRS rules carefully. You'll need to itemize your deductions and ensure the funds are used for home-related upgrades. The rules in place through 2025 limit deductibility, but those restrictions may ease in the future. Keeping detailed records, collecting your tax forms, and considering a consultation with a tax advisor can help you make the most of your potential deductions.
