Is HELOC Interest Tax Deductible? 2026 Rules
The short answer: it depends on how you use the funds. Here are the current IRS rules for deducting HELOC interest on your federal tax return.
The Quick Answer
Yes, if the HELOC funds are used to buy, build, or substantially improve the home that secures the HELOC, and you itemize deductions on your tax return.
No, if the funds are used for other purposes such as debt consolidation, car purchases, tuition, or medical bills.
Three Conditions for Deductibility
Funds Used for Home Improvement
The HELOC funds must be used to buy, build, or substantially improve the home that secures the loan. Painting a room does not qualify. Adding a room, replacing a roof, or installing a new HVAC system does. The IRS looks at whether the improvement adds value, extends the home's life, or adapts it to new uses.
Total Mortgage Debt Under $750,000
Your combined mortgage and HELOC debt cannot exceed $750,000 for married filing jointly ($375,000 for married filing separately). If your first mortgage is $600,000 and your HELOC is $200,000, only the interest on the first $150,000 of the HELOC is deductible (to stay within the $750,000 cap).
You Itemize Deductions
The HELOC interest deduction is only available if you itemize deductions on Schedule A rather than taking the standard deduction. For 2026, the standard deduction is approximately $15,000 for single filers and $30,000 for married filing jointly. If your total itemized deductions do not exceed the standard deduction, the HELOC interest deduction provides no benefit.
What Qualifies as "Substantial Improvement"?
| Improvement | Deductible? |
|---|---|
| Adding a room or wing | Yes |
| New roof replacement | Yes |
| New HVAC system | Yes |
| Kitchen or bathroom remodel | Yes |
| New windows or insulation | Yes |
| Swimming pool installation | Yes |
| Finishing a basement | Yes |
| Painting a room | No |
| Fixing a leaky faucet | No |
| Routine maintenance | No |
| Landscaping | Depends |
Landscaping may qualify if it is part of a larger improvement project (e.g., regrading for drainage as part of a foundation repair). Standalone cosmetic landscaping typically does not qualify.
What Does NOT Qualify
HELOC interest used for the following purposes is not tax deductible:
- ✗ Paying off credit card debt or personal loans
- ✗ Buying a car
- ✗ Paying college tuition
- ✗ Medical bills
- ✗ Vacation or travel expenses
- ✗ Starting or funding a business
- ✗ Investment purchases (stocks, real estate)
Standard Deduction vs Itemizing
The HELOC interest deduction only helps if your total itemized deductions exceed the standard deduction. For 2026, the standard deduction is approximately:
Single / Married Filing Separately
~$15,000
Married Filing Jointly
~$30,000
If your HELOC interest is $5,000 per year but your total itemized deductions (including state/local taxes, mortgage interest, and charitable contributions) only total $20,000, and the standard deduction is $30,000 for your filing status, you are better off taking the standard deduction. The HELOC interest deduction does not provide any additional tax benefit in this scenario.
Record Keeping Requirements
If you deduct HELOC interest, the IRS expects you to maintain documentation showing the funds were used for qualifying home improvements. Keep these records:
- ✓ HELOC draw dates and amounts matching contractor payment dates
- ✓ Contractor invoices and signed contracts
- ✓ Receipts for materials purchased
- ✓ Building permits (if applicable)
- ✓ Before and after photos (supporting documentation)
- ✓ Form 1098 from your lender showing interest paid
Keep these records for at least three years after filing the return (the standard IRS audit window). Some advisors recommend keeping them for seven years.
