Home Equity Loan and HELOC Interest Deduction Rules: When Is It Tax Deductible in 2026

# Home Equity Loan and HELOC Interest Deduction Rules: When Is It Tax Deductible in 2026

Introduction

Imagine this: You've just finished renovating your kitchen using a $50,000 home equity line of credit (HELOC), and now tax season is approaching. Your neighbor casually mentions over the fence that they deducted all their HELOC interest from their taxes. You're thinking, "Wait, I can do that too?" Well, maybe—but the answer isn't as simple as it used to be.

The short answer: In 2026, home equity loan and HELOC interest is tax deductible only if you use the borrowed money to buy, build, or substantially improve the home that secures the loan. If you used that money to pay off credit cards, buy a car, or fund your vacation, the interest isn't deductible, no matter how convincing your neighbor sounds.

This matters because the average HELOC interest rate hovers around 8-9% as of 2026, meaning that $50,000 loan could cost you $4,000-$4,500 in interest annually. If you're in the 24% tax bracket and that interest qualifies as deductible, you could save roughly $1,000 on your tax bill. But get it wrong, and you're leaving money on the table—or worse, triggering an IRS audit.

In this guide, we'll break down exactly when HELOC and home equity loan interest is tax deductible in 2026, what counts as qualified improvements, the dollar limits you need to know, and real examples that show you how these rules work in practice. Whether you're planning a home renovation or already paying interest on an existing loan, you'll walk away knowing exactly where you stand come tax time.

What Changed: The Tax Cuts and Jobs Act Impact on Home Equity Interest

The Tax Cuts and Jobs Act (TCJA) of 2017 fundamentally changed home equity loan deductibility, and these rules remain in effect through 2025 and into 2026. Before 2018, homeowners could deduct interest on up to $100,000 of home equity debt regardless of how they used the money. That's gone.

According to the IRS, starting in 2018 and continuing through at least 2026, you can only deduct interest on home equity loans and HELOCs if the funds are used to "buy, build, or substantially improve" the taxpayer's home that secures the loan. This is now classified as "qualified residence interest" under the same rules that govern mortgage interest deductions.

What This Means in Plain English

Here's the difference in practice:

Before 2018:

• Borrow $75,000 on a HELOC
• Use it for anything (college tuition, wedding, debt consolidation)
• Deduct the interest, up to the $100,000 limit

2018-2026 and Beyond:

• Borrow $75,000 on a HELOC
• Interest is ONLY deductible if used for home improvements on that property
• Use it for anything else = no deduction, period

This change caught many taxpayers off guard. According to the National Association of Realtors, approximately 40% of homeowners were still unaware of this rule change as of 2023, leading to common filing errors.

The Debt Limit: How Much Interest Can You Actually Deduct?

Under current law continuing through 2026, the total mortgage debt limit for deducting interest is $750,000 for married couples filing jointly ($375,000 if married filing separately). This limit applies to the combined total of:

• Your original mortgage
• Any refinanced mortgage balance
• Home equity loans
• HELOCs

Important exception: If you took out your mortgage before December 16, 2017, you're grandfathered into the old $1 million limit ($500,000 married filing separately).

What Qualifies as "Buy, Build, or Substantially Improve"?

To qualify for the deduction, your home equity borrowing must be used for capital improvements that add value to your home, prolong its useful life, or adapt it to new uses. Routine maintenance and repairs generally don't count.

Qualified Uses That Make Interest Deductible

According to IRS Publication 936, these improvements typically qualify:

Major Renovations:

• Kitchen remodels
• Bathroom additions or complete renovations
• Room additions
• Basement finishing
• Deck or patio construction
• New roof installation
• Window and door replacements (full home upgrades)
• HVAC system replacement
• Swimming pool installation
• Landscaping projects (extensive hardscaping)

Energy Improvements:

• Solar panel installation
• Geothermal heating systems
• Energy-efficient window upgrades
• Insulation improvements

Structural Work:

• Foundation repairs
• New siding
• Septic system installation
• Well drilling

What Doesn't Qualify

These expenses won't make your HELOC interest deductible:

• Credit card debt payoff
• Auto loans or vehicle purchases
• College tuition or student loans
• Wedding expenses
• Vacation costs
• Business investments
• Investment property purchases (unless the HELOC is secured by that property)
• Routine maintenance (painting, minor repairs, lawn mowing)
• Furniture and appliances (unless built-in during renovation)

The Gray Area: Repairs vs. Improvements

Here's where it gets tricky. The IRS distinguishes between repairs (not deductible) and improvements (deductible).

Repairs keep your home in good operating condition but don't add substantial value:

• Fixing a broken window
• Patching a roof leak
• Painting a room
• Fixing a broken furnace

Improvements add value, prolong life, or adapt to new uses:

• Replacing all windows in the home
• Installing a completely new roof
• Full interior repaint as part of renovation
• Replacing the entire HVAC system

The key test: Does it make your home more valuable than before, or just maintain its current condition?

Real-World Examples: Is Your HELOC Interest Deductible?

Let's walk through specific scenarios to see how these rules work in practice.

Example 1: The Kitchen Renovation (Deductible)

Scenario: Sarah and Tom take out a $60,000 HELOC in January 2026 to renovate their kitchen. They pay 8% interest, resulting in $4,800 in interest for the year.

Use of funds:

• New cabinets: $25,000
• Granite countertops: $12,000
• Appliances (built-in): $15,000
• Plumbing and electrical work: $8,000

Tax situation:

• Their original mortgage balance: $350,000
• Total home debt: $410,000 (under the $750,000 limit)
• They itemize deductions
• Tax bracket: 24%

Result: All $4,800 in HELOC interest is deductible as qualified residence interest. This saves them approximately $1,152 in federal taxes ($4,800 × 24%).

Example 2: The Debt Consolidation (Not Deductible)

Scenario: Mike borrows $40,000 via HELOC in March 2026 to consolidate credit card debt. He pays 9% interest, totaling $3,600 for the year.

Use of funds:

• Credit card payoff: $30,000
• Auto loan payoff: $10,000

Tax situation:

• Original mortgage: $280,000
• Total home debt: $320,000 (under the limit)
• He itemizes deductions
• Tax bracket: 22%

Result: None of the $3,600 in interest is deductible, even though his total debt is well under the $750,000 limit. The money wasn't used for home improvements, so it doesn't qualify. Mike gets no tax benefit from this interest.

Example 3: The Mixed-Use HELOC (Partially Deductible)

Scenario: Jennifer takes out a $100,000 HELOC in April 2026. She pays 8.5% interest, totaling $8,500 for the year.

Use of funds:

• Master bathroom renovation: $50,000
• Daughter's college tuition: $30,000
• Wedding expenses: $20,000

Tax situation:

• Original mortgage: $450,000
• Total home debt: $550,000 (under the limit)
• She itemizes deductions
• Tax bracket: 32%

Result: Only 50% of her interest is deductible—the portion used for the bathroom renovation. She can deduct $4,250 ($8,500 × 50%), saving approximately $1,360 in taxes ($4,250 × 32%).

Key lesson: The IRS requires you to trace how borrowed funds were used. Jennifer needs to keep clear documentation showing which funds went to the bathroom renovation versus other expenses.

Example 4: Exceeding the Debt Limit (Limited Deduction)

Scenario: Robert and Linda took out their original mortgage in 2019 for $700,000. In 2026, they still owe $650,000 on that mortgage and take out a $150,000 HELOC for a home addition. They pay 8% interest on the HELOC, totaling $12,000 for the year.

Total home debt: $800,000 ($650,000 mortgage + $150,000 HELOC)

Tax situation:

• Total debt exceeds the $750,000 limit by $50,000
• They itemize deductions
• Tax bracket: 35%

Result: Even though the entire HELOC was used for qualifying home improvements, they can only deduct interest on $750,000 of total debt. The deductible portion is calculated as:

$750,000 ÷ $800,000 = 93.75% of their total interest

From the HELOC interest alone: $12,000 × 93.75% = $11,250 is deductible (with similar proportional reduction on mortgage interest).

This saves them approximately $3,938 in taxes, but they lose the deduction on the remaining $750 in interest.

How to Actually Claim the Deduction: Forms and Documentation

To claim home equity loan or HELOC interest as a deduction, you must itemize deductions using Schedule A (Form 1040) and report the interest on the "Home mortgage interest and points" line. You cannot claim this deduction if you take the standard deduction.

The Standard Deduction Hurdle for 2026

According to the IRS, the standard deduction amounts for 2026 are projected to be approximately:

• Single filers: $15,000
• Married filing jointly: $30,000
• Head of household: $22,500

(Note: These are estimates based on inflation adjustments; official 2026 figures will be published by the IRS in late 2025)

Your total itemized deductions (including mortgage interest, HELOC interest, state and local taxes, charitable donations, and medical expenses) must exceed these amounts for itemizing to make financial sense.

Example: Should You Itemize?

Scenario: Mark and Jennifer are married and paid the following in 2026:

• Mortgage interest: $14,000
• HELOC interest (qualified): $4,500
• State and local taxes (SALT): $10,000 (the maximum allowed)
• Charitable donations: $3,000

Total itemized deductions: $31,500

Standard deduction: $30,000

Result: They should itemize, saving an extra $1,500 in deductions. If they're in the 24% bracket, this nets them an additional $360 in tax savings.

Required Forms and Documentation

Form 1098: Your lender should send you Form 1098 (Mortgage Interest Statement) by January 31, 2027, showing the interest you paid in 2026. This applies to mortgages and most home equity loans.

Schedule A: Report the interest on Schedule A, Line 8a or 8b, depending on whether you received Form 1098.

Documentation to Keep:

• HELOC or home equity loan statements
• Receipts and invoices for home improvements
• Contractor agreements and contracts
• Photos of before/after improvements
• Cancelled checks or bank statements showing payments to contractors
• Clear records showing the flow of money from loan to improvement expenses

According to tax professionals, the IRS may request proof that borrowed funds were actually used for qualifying improvements, especially if audited. Keeping a clear paper trail is essential.

How to Handle It with Tax Software

Both TurboTax and H&R Block offer step-by-step guidance for claiming home equity interest deductions. The software will:

• Ask you specific questions about how you used the borrowed funds
• Calculate the deductible portion if you had mixed use
• Help you determine if itemizing beats the standard deduction
• Automatically complete Schedule A with your information

For straightforward situations (HELOC used 100% for qualifying improvements, total debt under $750,000), the software handles this easily. For complex scenarios involving mixed use or debt limit calculations, consulting a CPA is advisable.

State Tax Considerations

Federal tax rules don't always match state tax rules for HELOC deductibility. Some states conform to federal law, while others have different requirements.

States That Generally Follow Federal Rules

Most states that have income tax conform to the federal treatment of home equity interest, including:

• California
• New York
• Illinois
• Pennsylvania
• North Carolina

States with Different Rules

Some states diverged from federal law after the TCJA:

New Jersey: According to the New Jersey Division of Taxation, the state allows a broader deduction than federal law for tax years 2018-2025. Homeowners may still deduct interest on up to $500,000 of home equity debt even if not used for home improvements (for state purposes only).

California: While generally following federal rules, California has different debt limits and may treat certain refinanced mortgages differently.

Always check your specific state's Department of Revenue guidelines, as these rules can change annually.

Special Situations and Edge Cases

Rental Properties and Second Homes

The deduction rules apply differently depending on which property secures the loan:

Second home: If your HELOC is secured by a qualified second home (where you live part-time), interest may be deductible if used to improve that second home. The $750,000 debt limit applies to both homes combined.

Rental property: If you take a HELOC on your primary residence to improve a rental property you own, that interest is NOT deductible as qualified residence interest. However, it may be deductible as a rental property expense on Schedule E.

HELOC on rental property: If the HELOC is secured by the rental property itself and used to improve it, the interest is deductible as a business expense, not subject to the same limitations.

Home Equity Loans vs. Cash-Out Refinancing

What's the difference for tax purposes?

Home equity loan/HELOC: A separate loan with its own interest rate, taken against your home equity.

Cash-out refinance: Replacing your existing mortgage with a larger one and taking the difference in cash.

For deduction purposes, the same rules apply: interest is only deductible on the amount used to buy, build, or substantially improve your home.

Example: You refinance your $300,000 mortgage into a new $400,000 mortgage, taking $100,000 cash. If you use that $100,000 for a home addition, the interest on the full $400,000 is deductible (assuming you're under the $750,000 limit). If you use it to buy a boat, only the interest on $300,000 is deductible.

Divorced Homeowners

If you're divorced and one spouse remains in the home while the other pays the mortgage or HELOC:

According to IRS Publication 504, the spouse who pays the interest can only deduct it if they legally own the home. If the home is solely in the ex-spouse's name, the paying spouse generally cannot claim the deduction.

Special rules apply if the payment is part of a divorce agreement and qualifies as alimony—consult a tax professional for these situations.

Points and Origination Fees

When you take out a HELOC or home equity loan, you may pay:

• Origination fees
• Points (prepaid interest)
• Closing costs

Points paid on a home equity loan may be deductible, but unlike points on a primary mortgage, they generally must be deducted over the life of the loan rather than all at once. If you paid $2,000 in points on a 10-year HELOC, you'd deduct $200 per year.

This only applies if the HELOC was used for qualifying home improvements.

Record-Keeping Best Practices

The burden of proof is on you to demonstrate that your HELOC funds were used for qualifying improvements. Here's how to protect yourself:

Create a Paper Trail

1. Separate account: Consider having your lender deposit HELOC funds into a separate bank account used only for home improvement expenses.

2. Detailed invoices: Get itemized invoices from contractors showing: - Specific work performed - Materials used - Labor costs - Dates of service

3. Payment records: Pay contractors directly from the HELOC-funded account via check or traceable bank transfer (avoid cash).

4. Before/after photos: Document the improvements visually with dated photographs.

5. Permits and approvals: Keep copies of building permits, which prove the work was substantial.

How Long to Keep Records

According to the IRS, you should keep tax records for at least three years from the date you filed the return. However, for property-related documentation (including home improvements), many tax professionals recommend keeping records for as long as you own the home, plus seven years after you sell it.

Why? Home improvements increase your cost basis in the home, potentially reducing capital gains tax when you sell. You'll need this documentation years or decades later.

Organize with These Categories

Create a file (physical or digital) with these sections:

• Loan documents: HELOC agreement, promissory note, closing disclosure
• Interest statements: All Form 1098s and monthly statements
• Improvement contracts: Signed agreements with contractors
• Invoices and receipts: All payments for materials and labor
• Bank statements: Showing fund transfers from HELOC to contractors
• Photos: Before, during, and after improvement work
• Permits: Building permits and final inspections

Planning Strategies for Maximum Deduction

Timing Your HELOC for Tax Efficiency

Strategy 1: Bunch improvements in years when you'll itemize

If you're close to the standard deduction threshold, consider concentrating improvements (and HELOC borrowing) in alternate years.

Example: Instead of spreading a $100,000 renovation over 2026 and 2027, complete it all in 2026. This generates more deductible interest in one year, potentially pushing you over the itemization threshold.

Strategy 2: Coordinate with other deductible expenses

If you know you'll have high medical expenses or plan major charitable donations in a particular year, that might be the ideal time to take out a HELOC and claim the interest deduction while itemizing.

Should You Use a HELOC or Save for Renovations?

Tax considerations alone shouldn't drive this decision, but here's the math:

Scenario: You need $50,000 for a kitchen renovation. You can either:

A) Save for 2 years and pay cash B) Take a HELOC at 8.5% interest

HELOC approach (assuming 24% tax bracket):

• Year 1 interest: ~$4,250
• Tax savings from deduction: ~$1,020
• Net interest cost after tax benefit: ~$3,230

Savings approach:

• No interest costs
• But renovation delayed 2 years
• Home value appreciation during delay (potentially lost equity)

The right choice depends on:

• Your emergency fund status
• Whether you'll itemize deductions
• Current home equity levels
• Interest rate environment
• Urgency of the improvement

The Refinancing Decision

With mortgage rates fluctuating, you might wonder: Should I refinance my mortgage with cash-out, or take a separate HELOC?

Cash-out refinance might be better if:

• Current mortgage rates are lower than your existing rate
• You want one monthly payment
• You plan to keep the loan long-term

HELOC might be better if:

• Current rates are higher than your existing mortgage
• You want flexibility to borrow and repay over time
• You might pay it off quickly
• You want to keep your low existing mortgage rate intact

From a tax perspective, both can offer the same deduction as long as funds are used for qualifying improvements and you stay under the $750,000 combined debt limit.

Common Mistakes to Avoid

Mistake 1: Assuming All HELOC Interest Is Deductible

The problem: Many homeowners remember the old rules (pre-2018) and assume HELOC interest is automatically deductible.

The fix: Always verify that borrowed funds were used to buy, build, or substantially improve your home. If not, don't claim the deduction.

Mistake 2: Poor Documentation

The problem: You did use the HELOC for qualifying improvements, but you can't prove it in an audit because you paid cash to contractors or threw away receipts.

The fix: Implement the record-keeping system outlined earlier. Treat this as seriously as you would any other $1,000+ tax deduction.

Mistake 3: Taking the Standard Deduction and Claiming Interest

The problem: You can't do both. Some taxpayers mistakenly claim home equity interest while also taking the standard deduction.

The fix: Use tax software like TurboTax or H&R Block that automatically prevents this error, or work with a CPA who will calculate whether itemizing or taking the standard deduction is better for your situation.

Mistake 4: Deducting Interest on Excess Debt

The problem: Your total mortgage debt exceeds $750,000, but you deduct 100% of your HELOC interest anyway.

The fix: Calculate the proportional deduction based on the $750,000 limit, as shown in Example 4 earlier.

Mistake 5: Mixing Personal and Improvement Expenses

The problem: You took out $80,000—used $60,000 for a bathroom renovation and $20,000 for a family vacation—but you deduct interest on the full amount.

The fix: Trace the use of funds precisely and only deduct the proportional interest related to home improvements (75% in this case).

What Happens in 2026 and Beyond?

Current law (the Tax Cuts and Jobs Act provisions) is scheduled to expire after 2025, which means significant changes could occur in 2026 unless Congress acts.

Potential Scenarios for 2026

Scenario 1: Extension of current rules Congress could extend the TCJA provisions, keeping the $750,000 debt limit and use restrictions in place.

Scenario 2: Reversion to pre-2018 rules Without action, some provisions could revert to pre-TCJA law, potentially bringing back the $100,000 home equity debt allowance for any purpose. However, this is considered unlikely.

Scenario 3: New legislation Congress could pass entirely new rules with different limits and qualifications.

What to Watch For

As of late 2025, watch for IRS guidance and Congressional action on:

• Extension or modification of the $750,000 debt limit
• Changes to the "substantial improvement" use requirement
• Adjustments to state and local tax deduction caps (which affect the itemization calculation)

For 2026 planning purposes, assume current rules remain in effect unless you hear otherwise. The IRS will publish official guidance for the 2026 tax year by late 2025 or early 2026.

FAQ

Q: Can I deduct HELOC interest if I use the money to pay off credit card debt?

A: No. Under current law through 2026, HELOC interest is only deductible if you use the borrowed funds to buy, build, or substantially improve the home that secures the loan. Using HELOC proceeds to pay off credit cards, car loans, or other personal debt does not qualify for the tax deduction, even though the loan is secured by your home. The IRS requires tracing of how the funds were actually used, and only the portion used for qualifying home improvements generates deductible interest.

Q: Do I need to itemize deductions to claim HELOC interest?

A: Yes. Home equity loan and HELOC interest must be claimed as an itemized deduction on Schedule A of Form 1040. If you take the standard deduction (approximately $30,000 for married couples filing jointly in 2026), you cannot also claim HELOC interest. For the deduction to benefit you, your total itemized deductions—including mortgage interest, HELOC interest, state and local taxes (up to $10,000), charitable donations, and qualifying medical expenses—must exceed the standard deduction amount for your filing status.

Q: What's the maximum amount of HELOC interest I can deduct in 2026?

A: The deduction limit is based on total home debt, not specifically on HELOC amount. For mortgages and home equity loans taken out after December 15, 2017, you can deduct interest on up to $750,000 of combined debt ($375,000 if married filing separately) when the funds are used to buy, build, or substantially improve your qualified residence. If you took out your original mortgage before December 16, 2017, you're grandfathered into the higher $1 million limit. There's no specific separate limit for HELOC interest—it all counts toward your total qualified residence debt.

Q: Does replacing my roof or HVAC system count as a "substantial improvement"?

A: Yes. According to IRS guidelines, replacing a roof or HVAC system qualifies as a substantial improvement because these projects extend the useful life of your home and add value. These are capital improvements, not routine repairs. Interest on HELOC funds used for these projects is deductible. However, simply repairing a few damaged shingles or fixing a broken furnace component would be considered maintenance (not deductible). The distinction is whether you're restoring existing functionality (repair) or substantially upgrading/replacing a major system (improvement).

Q: Can I deduct interest on a HELOC secured by a rental property?

A: The deductibility depends on which property secures the loan and how you use the funds. If the HELOC is secured by your primary residence but used to improve a rental property, the interest is NOT deductible as qualified residence interest. However, if the HELOC is secured by the rental property itself and used to improve that property, the interest is deductible as a rental business expense on Schedule E (subject to different rules and limits than qualified residence interest). Always trace both the security property and the use of funds to determine the correct tax treatment.

People Also Ask

How much mortgage interest can you write off on your taxes in 2026?

For mortgages taken after December 15, 2017, you can deduct interest on up to $750,000 of qualified residence debt ($375,000 if married filing separately) when you itemize deductions. This limit applies to your combined total of mortgage debt and qualifying home equity debt on your primary residence and one second home. If your mortgage predates December 16, 2017, you're grandfathered into the previous $1 million limit.

What is the difference between a home equity loan and a HELOC?

A home equity loan provides a lump sum with a fixed interest rate and fixed monthly payments over a set term, similar to your original mortgage. A HELOC (Home Equity Line of Credit) works more like a credit card secured by your home—you have a credit limit and can borrow, repay, and re-borrow during a "draw period" (typically 10 years), usually with a variable interest rate. For tax purposes, both are treated identically: interest is only deductible when funds are used to buy, build, or substantially improve your home.

Are closing costs on a HELOC tax deductible?

Closing costs on a HELOC are generally not deductible in the year paid. However, points (prepaid interest) may be deductible over the life of the loan if the HELOC was used for qualifying home improvements. For example, if you paid $2,000 in points on a 10-year HELOC used for home improvements, you could deduct $200 per year for 10 years. Other closing costs like appraisal fees, title insurance, and attorney fees are not deductible for personal residence HELOCs. These rules apply only when you itemize deductions.

Should I take a HELOC or a home equity loan for home improvements?

The choice depends on your needs rather than tax implications (both offer identical deduction treatment). Choose a HELOC if you want flexibility—you can borrow amounts as needed during renovations, only paying interest on what you actually draw. This works well for phased projects or uncertain total costs. Choose a home equity loan if you know exactly how much you need and prefer the stability of fixed payments and a fixed interest rate. From a tax perspective, as long as you use the borrowed funds for qualifying improvements and stay under the $750,000 combined debt limit, the deduction is the same.

How does the home equity interest deduction affect your tax refund?

The HELOC interest deduction reduces your taxable income, not your tax refund directly. If you paid $5,000 in deductible HELOC interest and you're in the 24% tax bracket, your tax liability decreases by about $1,200 ($5,000 × 24%). Whether this increases your refund or decreases what you owe depends on your overall tax situation and withholding throughout the year. If you had too much tax withheld from your paycheck, this additional $1,200 deduction would increase your refund by approximately that amount; if you underwitheld, it would reduce the amount you owe by about $1,200.

Conclusion

Understanding HELOC and home equity loan interest deduction rules for 2026 boils down to one critical requirement: you must use the borrowed money to buy, build, or substantially improve the home securing the loan. Use it for anything else—debt consolidation, vehicles, vacations, or education—and the interest won't reduce your tax bill, no matter how much you paid.

The key takeaways to remember:

• The $750,000 combined debt limit applies to all your mortgage and home equity debt taken after December 15, 2017
• You must itemize to claim the deduction, which only makes sense if your total itemized deductions exceed the standard deduction (approximately $30,000 for married couples in 2026)
• Documentation is crucial—keep detailed records showing how HELOC funds were used, with receipts, contracts, and photos
• Substantial improvements qualify, including kitchen/bathroom remodels, additions, new roofs, HVAC replacement, and major systems upgrades
• Routine maintenance doesn't qualify, even if you used HELOC funds to pay for it

If you're planning to take out a HELOC or home equity loan in 2026, start with clear documentation from day one. Open a separate account for the funds, pay contractors with traceable payments, and keep every receipt. The interest deduction can save you thousands—in our examples, homeowners in the 24% bracket saved $1,000-$1,500 annually—but only if you can prove the funds were used correctly.

For your next steps:

1. Review your current situation: If you have an existing HELOC, confirm how you used the funds and whether you've been correctly claiming (or not claiming) the deduction.

2. Calculate whether to itemize: Add up your potential itemized deductions including mortgage interest, HELOC interest, state and local taxes (capped at $10,000), and charitable donations to see if you'll exceed the standard deduction.

3. Plan your 2026 improvements: If you're considering major home improvements, understand how HELOC interest deductibility factors into the total cost.

4. Use professional help when needed: For complex situations involving mixed-use funds, debt over the $750,000 limit, or multiple properties, consider using tax software like TurboTax or H&R Block, or consult with a qualified CPA who can optimize your specific situation.

The tax laws around home equity borrowing have fundamentally changed since 2018, but with proper planning and documentation, you can still capture valuable tax savings when improving your home. Just make sure every dollar you borrow goes toward making your home better, and keep the receipts to prove it.
