Interest paid towards a home equity loan and HELOC can be tax-deductible, but only under specific conditions. The loan must be used to buy, build, or substantially improve your primary or secondary home (qualified residence). Deductibility also depends on whether you itemize your deductions and whether your total home acquisition debt stays within the IRS cap.
- In addition to home equity interest, premiums paid on Private Mortgage Insurance (PMI) are deductible as mortgage interest for taxpayers with an adjusted gross income below the IRS phase-out threshold.
- To benefit from these tax write-offs, you must itemize your deductions on Schedule A instead of claiming the standard deduction.
- Deductible interest is capped at $750,000 of total home acquisition debt (for loans taken out after December 15, 2017).
Are HELOCs Tax Deductible?
The full HELOC, no.
The interest paid on the HELOC, maybe.
Whether the interest you pay on your home equity loan or Home Equity Line of Credit (HELOC) is deductible depends on how you used the money, how much you borrowed, and how you file your taxes.
Let’s break it all down so you know what this type of interest deduction means for your tax filing.

What Parts of a Home Equity Loan Are Actually Deductible?
Before diving into interest, it helps to understand what the IRS does and doesn’t allow you to deduct.
Loan Proceeds
When you take out a home equity loan or HELOC, the funds disbursed to you are called loan proceeds. Like other forms of debt, loan proceeds are not taxable income—but they’re also not deductible.
Loan Fees
Closing costs, annual fees, and origination fees are not deductible on your individual federal tax return.
Loan Principal
The principal is the original amount you borrowed.
Think of it like the price tag on a car. When you make monthly payments, a portion goes toward principal and a portion goes toward interest. Only the interest portion may be deductible. The principal repayment is not.
Here’s a quick example: You make a $500 HELOC payment this month. $350 goes to principal, $150 goes to interest. Only that $150 has any chance of being deductible.

Qualified Residence
To deduct home equity loan or HELOC interest, the loan must be secured by a qualified residence.
A qualified residence is your main home (where you live most of the time) or one second home you own.
The IRS defines a qualified home as a house, condo, co-op, mobile home, or houseboat with sleeping, cooking, and toilet facilities that serves as collateral for the loan. For complete details on qualified residence interest rules, see IRS Publication 936.
When Is HELOC Interest Tax-Deductible?
Three factors determine whether you can deduct your home equity loan or HELOC interest. All three need to point in the right direction.
1. You Must Itemize Your Deductions
Home mortgage interest, including HELOC interest, is an itemized deduction. That means you can only claim it if your total itemized deductions exceed the standard deduction.
For the 2026 tax year (returns filed in 2027), the standard deduction is:
- $16,100 for single filers
- $32,200 for married filing jointly
- $24,150 for head of household
So, for your HELOC interest to provide a real tax benefit, it needs to push your total itemized deductions — which can include state and local taxes, property taxes, charitable contributions, and more — above those thresholds. If your itemized deductions fall short, you’re likely better off taking the standard deduction.
2. How You Used the Funds Matters — A Lot
For your HELOC or home equity loan interest to be deductible, the funds must have been used to buy, build, or substantially improve the home that secures the loan.
If you used those same funds to pay off credit cards, cover living expenses, or fund a vacation, the interest is not deductible.
| How You Used the Funds | Deductible? |
|---|---|
| Home renovation or addition | ✅ Yes (subject to debt limits) |
| Buying or building your home | ✅ Yes (subject to debt limits) |
| Paying off credit card debt | ❌ No |
| Personal living expenses | ❌ No |
3. Your Total Home Acquisition Debt Must Be Within the Limit
Even if you check the first two boxes, there’s a dollar cap to be aware of.
The $750,000 Debt Limit — Now Permanent
Home acquisition debt incurred after December 15, 2017 is only fully deductible on balances up to $750,000.
Here’s a real-world example:
You purchased a home in 2020 and took on $600,000 in mortgage debt. In 2024, you took out a $200,000 HELOC to add an upstairs unit. Your total home acquisition debt is now $800,000 — $50,000 over the $750,000 limit.
That means you can only deduct interest on $750,000 of that debt. The interest tied to the remaining $50,000 is not deductible.
Pre-December 15, 2017 debt: If your home acquisition debt was incurred before that date, the older $1,000,000 cap still applies to that portion of your debt.
This calculation can get complicated quickly, especially if you have a mix of old and new debt. A tax professional will have the formulas and software to calculate the exact deductible portion for your return.
New for 2026: PMI Premiums Are Now Deductible
Starting with tax year 2026, premiums paid for Private Mortgage Insurance (PMI) are deductible as mortgage interest.
PMI is typically required when your down payment is less than 20% of the home’s purchase price. If you’re paying it, that cost can now work in your favor at tax time. It’s treated the same as mortgage interest and reported on Schedule A.
Keep in mind: This deduction phases out once your Adjusted Gross Income (AGI) exceeds $100,000 (or $50,000 if married filing separately). It applies to the 2026 tax year forward, not your 2025 return.
Don’t Forget About the Alternative Minimum Tax (AMT)
If your income is on the higher end, the Alternative Minimum Tax (AMT) could affect how much you actually benefit from the mortgage interest deduction.
The AMT is a parallel tax system designed to ensure higher-income earners pay a minimum level of tax regardless of deductions. Under AMT rules, certain deductions get added back into your taxable income, though mortgage interest on qualified home acquisition debt remains deductible under both systems.
Here’s the simplified version: You calculate your tax two ways; the regular way and the AMT way. You pay whichever is higher.
AMT Exemption Amounts for 2026
The exemption amount is the portion of your income that’s shielded from AMT, but it begins to phase out (decrease) once your AMT income exceeds the phaseout threshold, eventually eliminating the exemption entirely for very high incomes.
If you paid AMT in a prior year, you may be eligible for a minimum tax credit. File Form 8801 (Credit for Prior Year Minimum Tax) to claim it.
What About State Tax Deductions?
Good news: most states with an income tax offer their own version of the mortgage interest deduction. The specifics vary by state, so check with your tax professional about what applies where you live.
Frequently Asked Questions
What if I used my HELOC to pay off credit cards?
The interest is not deductible. Under the permanent rules established by the OBBBA, interest on funds used for personal expenses, including debt consolidation, is not deductible, even if the loan is secured by your home.
Does it matter when I took out the loan?
Yes. Loans taken out after December 15, 2017 are subject to the $750,000 debt cap. Debt incurred before that date is subject to the older $1,000,000 cap. The OBBBA made the $750,000 cap permanent for new debt going forward, so the old rules will only ever apply to pre-2018 balances.
What’s the difference between home acquisition debt and home equity debt?
Home acquisition debt is debt used to buy, build, or substantially improve a home. Under current permanent law, this is the only type of home-secured debt eligible for the mortgage interest deduction. Interest on debt used for any other purpose, sometimes called home equity debt, is not deductible.
Should I itemize or take the standard deduction for 2026?
It depends on your total deductible expenses. If your mortgage interest, state and local taxes, charitable contributions, and other itemized deductions exceed $15,750 (single) or $31,500 (married filing jointly) for the 2025 tax year, itemizing will likely save you more. With the standard deduction now significantly higher than before the OBBBA, fewer taxpayers will benefit from itemizing — which makes it even more important to run the numbers with a CPA.
What changed under the One Big Beautiful Bill Act (OBBBA)?
The OBBBA, signed in 2025, made permanent several TCJA provisions that were originally set to expire after 2025. For homeowners, the biggest changes are: (1) the $750,000 home acquisition debt cap is now permanent, (2) the use-of-funds requirement for HELOC interest deductibility is now permanent, and (3) PMI premiums become deductible as mortgage interest starting tax year 2026. The standard deduction was also increased.
So, Is HELOC Interest Tax-Deductible? Here’s the Bottom Line
In true CPA fashion, it depends. But here’s a quick checklist to cut through the noise:
- You itemize your deductions
- You used the loan proceeds to buy, build, or substantially improve a qualified residence
- Your total home acquisition debt doesn’t exceed $750,000 (for post-December 15, 2017 debt)
- AMT doesn’t eliminate your benefit
Talk to a tax professional before assuming you will or will not qualify for the deduction.
