Quick Answer
Home equity loan interest is deductible only if you use the funds to buy, build, or substantially improve your home. Under current tax law, you can deduct interest on up to $750,000 of qualifying home acquisition debt, but not if you used the loan for other purposes like debt consolidation or personal expenses.

When home equity loan interest is deductible
Home equity loan interest is deductible when you use the borrowed funds to "buy, build, or substantially improve" your home, according to [IRS Publication 936](https://www.irs.gov/pub/irs-pdf/p936.pdf). This is a significant change from pre-2018 rules, where home equity interest was generally deductible regardless of how you used the money.
The key test: What did you do with the loan proceeds? If you used the money for home improvements, the interest is deductible as mortgage interest. If you used it for other purposes — even smart financial moves like paying off credit cards — the interest is not deductible.
Example: $75,000 home equity loan scenarios
Let's say you take out a $75,000 home equity loan at 7% interest, costing you $5,250 annually in interest payments.
Scenario 1: Kitchen renovation ($75,000)
Scenario 2: Mixed use ($40,000 kitchen + $35,000 debt consolidation)
Scenario 3: Debt consolidation only ($75,000)
The $750,000 debt limit
Your total qualifying home debt (original mortgage + home equity loan used for improvements) cannot exceed $750,000 for the interest to be fully deductible. For married filing separately, the limit is $375,000.
If you exceed these limits, you can only deduct interest on the portion that falls within the cap.
What qualifies as "substantial improvement"
According to IRS guidance, improvements must add value to your home, prolong its useful life, or adapt it to new uses. Examples include:
Record-keeping requirements
The IRS requires you to maintain detailed records proving how you used the home equity loan funds:
Without proper documentation, the IRS may disallow the entire deduction during an audit.
What you should do
1. Review your loan documents to confirm how much you borrowed and the interest rate
2. Gather receipts for all home improvements funded by the loan
3. Calculate your deductible interest based on the percentage used for qualifying improvements
4. Consider itemizing if your total deductions (including this interest) exceed the $15,000 standard deduction
5. Use our return scanner to identify if you missed claiming this deduction on previous returns
Key takeaway: Home equity loan interest is only deductible if you used the money for home improvements, not personal expenses. Proper documentation is essential, and the interest could save you $1,000+ annually in taxes if you're in a higher tax bracket.
Key Takeaway: Home equity loan interest is deductible only when used for home improvements, potentially saving high earners $1,000+ annually, but requires detailed documentation to prove qualifying use.
Home equity loan interest deductibility based on use of funds
| Use of Funds | Interest Deductible? | Where to Deduct | Tax Impact (24% Bracket) |
|---|---|---|---|
| Home improvements | Yes | Schedule A (mortgage interest) | $1,260 on $5,250 interest |
| Debt consolidation | No | Not deductible | $0 |
| Personal expenses | No | Not deductible | $0 |
| Business purposes | Maybe | Schedule C (business expense) | $1,260 + SE tax savings |
| Investment property | Yes (if used for property) | Schedule E | $1,260 on $5,250 interest |

Bad news for debt consolidation borrowers
If you used your home equity loan to consolidate debt, pay for college, buy a car, or fund other personal expenses, the interest is not tax deductible under current law. This represents a major change from pre-2018 tax rules.
Why this hurts: Many homeowners took out home equity loans specifically because they believed the interest would be deductible. A $50,000 home equity loan at 6.5% costs $3,250 annually in interest — money that used to generate tax savings but no longer does.
The planning mistake
Before 2018, you could deduct home equity interest on loans up to $100,000 regardless of use. Many financial advisors recommended home equity loans for debt consolidation because:
Now, only the first two benefits remain, making the strategy less attractive.
Partial deduction strategies
If you have an existing home equity loan used for non-qualifying purposes, consider these approaches:
Future improvements: If you're planning home renovations, use cash or savings for improvements and apply your home equity loan payments toward those costs (with proper documentation).
Refinancing approach: Some homeowners refinance their primary mortgage to include home equity debt, then use the extra cash for home improvements. This requires careful planning and may not make sense given current interest rates.
What you should do
1. Accept reality: If you used the loan for debt consolidation, the interest isn't deductible
2. Focus on payoff: Without the tax benefit, prioritize paying down this debt faster
3. Plan future improvements: If you need home improvements, document carefully to ensure deductibility
4. Review other deductions: Make sure you're not missing other itemized deductions that could reduce your tax bill
Key takeaway: Home equity loans used for debt consolidation generate no tax benefits, making them less attractive than pre-2018 and worth paying off aggressively.
Key Takeaway: Home equity loans used for debt consolidation offer no tax deduction, eliminating a key financial benefit that made this strategy popular before 2018.

Business use creates a different deduction path
If you used your home equity loan for legitimate business purposes, the interest may be deductible as a business expense rather than mortgage interest — but the rules are complex and the deduction location matters.
Key distinction: Business interest deductions appear on Schedule C (sole proprietorships) or your business tax return, not as itemized deductions on Schedule A. This can be more valuable because business deductions reduce both income tax and self-employment tax.
Documentation requirements are stricter
For business use, you need comprehensive records:
Example: You borrow $60,000 against your home equity. $40,000 goes toward business equipment and $20,000 toward a family vacation. Only 67% of the interest ($40,000 ÷ $60,000) qualifies as a business deduction.
Interest expense limitations
Business interest deductions face additional limits:
Home office complications
If you used home equity funds to improve your home office space, the deduction treatment depends on specifics:
Key takeaway: Home equity interest used for legitimate business purposes may be deductible as a business expense, potentially more valuable than mortgage interest deduction, but requires meticulous documentation and may face additional limitations.
Key Takeaway: Business use of home equity funds may qualify for business interest deductions, which can be more valuable than mortgage interest deductions but require strict documentation and face additional tax limitations.
