The Tax Benefits of Owning a Home

Owning a home doesn’t just build long-term wealth — it can also unlock meaningful tax savings each year. Some benefits reduce the income you’re taxed on (deductions), while others cut your tax bill dollar-for-dollar (credits). Knowing which rules apply to your situation can be worth hundreds or even thousands of dollars at filing time.

Below is a clear, up-to-date breakdown of the most valuable federal homeowner tax perks for the 2025 tax year, plus what to document so you don’t miss a thing.

Key Takeaways

• Homeowners may qualify for major tax deductions (mortgage interest, property taxes, points, some home-equity interest) and tax credits (energy-efficiency upgrades, renewable energy systems, Mortgage Credit Certificates). IRS+1
• The mortgage interest deduction generally lets itemizers deduct interest on up to $750,000 of qualifying mortgage debt ($375,000 if married filing separately).
• The property tax deduction is part of the SALT limit: $10,000 cap through 2024 and $40,000 cap for 2025 (with a phase-out for higher incomes).
• Energy credits are a “use-them-now” deal in 2025: §25C and §25D credits remain at 30% but expire after December 31, 2025 under current law.
• Qualifying lower- and moderate-income buyers with a Mortgage Credit Certificate (MCC) can claim a mortgage interest credit up to $2,000/year.
• When selling a primary residence, eligible homeowners can exclude up to $250,000 of capital gains ($500,000 for joint filers). IRS

Deductions vs. Credits: What’s the Difference?

Before diving into specifics, it helps to know how these two tax breaks work:

• Tax deductions reduce your taxable income.
  Example: If you earn $80,000 and claim $6,000 in deductions, you’re taxed on $74,000 instead.
• Tax credits reduce your tax bill directly.
  Example: If you owe $3,000 and claim a $1,000 credit, your final bill drops to $2,000.

Most homeowner benefits are deductions — but a few credits can be even more powerful because they lower taxes dollar-for-dollar.

1. Mortgage Interest Deduction

For many homeowners who itemize, mortgage interest is the biggest tax break available. You can generally deduct interest paid on loans used to buy, build, or substantially improve your main home or one second home. IRS+1

Key Rules

• Interest is deductible on up to $750,000 of qualifying mortgage debt for loans originated after December 15, 2017. Nolo+1
• If your mortgage is older than that, the limit may be $1 million. IRS
• Married filing separately: $375,000 cap for newer loans. Tax Shark
• You must itemize deductions on Schedule A to claim it. IRS+1

Example

If you bought a home for $600,000 in 2022 and paid about $35,000 in mortgage interest this year, you could deduct that full amount if you itemize.

Documentation: Your lender sends Form 1098 every January showing your deductible interest.

2. Property Tax Deduction (SALT)

Property taxes can also be deductible if you itemize — but they fall under the State and Local Tax (SALT) cap. IRS+1

What Counts

You can deduct real estate taxes assessed uniformly on your property value and charged yearly by your local tax authority.

Not deductible: utility charges, HOA fees, trash/water fees, or special assessments for improvements like sidewalks unless separately stated as maintenance. IRS

SALT Limits (Big Change in 2025)

• 2018–2024: SALT deduction capped at $10,000 per return ($5,000 MFS).
• 2025: cap increases to $40,000 ($20,000 MFS).
• Phase-out: the $40,000 cap begins shrinking for taxpayers with MAGI over $500,000 and drops back to $10,000 at about $600,000. Kiplinger+1

Escrow Tip

If you pay taxes via escrow, deduct only what your lender actually paid out during the year — not what you deposited.

3. Mortgage Points Deduction

Mortgage points are upfront fees you may pay to lower your interest rate. In many cases, points count as prepaid interest and are deductible. IRS

When You Can Deduct Points Fully in the Purchase Year

You may deduct all points in the year you buy if:

• The loan is for your primary residence,
• Paying points is a normal practice in your area, and
• You paid them directly at closing (not rolled into the loan). IRS

Otherwise, you usually spread the deduction over the loan life.

Example

You paid $6,000 in points on a $600,000 mortgage. If it meets IRS rules, you may deduct the full $6,000 this year.

4. Home Equity Loan or HELOC Interest

Home-equity interest is deductible only when the funds are used to buy, build, or substantially improve the home that secures the loan. IRS+1

Example

• HELOC for a kitchen remodel → interest may be deductible.
• HELOC to pay off credit cards or take a vacation → not deductible.

Keep receipts showing how the funds were used.

5. Energy Efficient Home Improvement Credit (IRC §25C)

This credit covers 30% of qualifying energy-efficient upgrades to an existing home — but 2025 is the last year to claim it under current law. IRS+2IRS+2

• Eligible Improvements
• Exterior windows/skylights
• Exterior doors
• Insulation and air sealing
• Heat pumps and heat-pump water heaters
• Certain high-efficiency HVAC and water heaters
• Home energy audits IRS

Annual Caps (2025)

• $1,200/year for most improvements
• Windows/skylights: $600 cap
• Doors: $250 per door, $500 total
• Energy audits: $150 cap
• $2,000/year for heat pumps, heat-pump water heaters, biomass stoves/boilers

Example

You install $5,000 in qualifying windows.
30% credit = $1,500, but window cap = $600 → your credit is $600.

6. Residential Clean Energy Credit

If you install renewable systems like solar, geothermal, wind, or battery storage, you can claim 30% of eligible costs, including labor. Like §25C, it currently expires after Dec 31, 2025. Clean Energy Resource Teams+2IRS+2

What Qualifies

• Solar panels and solar water heating
• Wind turbines
• Geothermal heat pumps
• Fuel cells (with special limits)
• Battery storage paired with renewables Clean Energy Resource Teams

Example

A $20,000 solar install in 2025 → 30% credit = $6,000.

If the credit is larger than your tax bill, you can carry the extra forward to future years.

Note: IRS guidance in 2025 adds extra reporting for some equipment placed in service in 2025, so keep manufacturer paperwork. IRS

7. Mortgage Interest Credit (Mortgage Credit Certificate / MCC)

This is a lesser-known but valuable benefit for qualifying buyers. If your state or local housing agency issued you an MCC, you may claim a federal credit equal to a percentage of your mortgage interest.

Highlights

• Credit rate is set by the certificate (often 10%–50%).
• Max credit: $2,000/year.
• Claimed on Form 8396 every year you hold the mortgage.

Who Usually Qualifies

Programs vary, but MCCs typically target:

• First-time buyers
• Buyers in “target areas”
• Households under income and purchase-price limits
• Owner-occupants with a new mortgage (not most refinances) LegalClarity

Important: If you sell within nine years, you might owe some recapture tax, depending on your gain and income. Accountably

8. Selling Your Home: Capital Gains Exclusion

When you sell a primary residence, you may exclude:

• Up to $250,000 of gain (single)
• Up to $500,000 of gain (married filing jointly) IRS

Basic Requirements

• Owned the home 2 of the last 5 years
• Lived in it as your main home 2 of the last 5 years
• Generally can use the exclusion once every two years IRS

Example

Buy at $300,000, sell at $550,000 → gain $250,000.
If you meet the rules, you can potentially exclude the entire gain.

Pro move: Keep receipts for major improvements. They raise your “cost basis,” reducing taxable gain if you exceed the exclusion.

State and Local Incentives

Many states stack extra perks on top of federal rules — especially for renewable energy or efficiency upgrades. These can include rebates, property-tax exclusions, or local credits. Check your state energy office or city/county programs for current offerings. IRS

Timing & Compliance Tips

Watch the Calendar

Because §25C and §25D credits expire after December 31, 2025, upgrades need to be placed in service by that date to qualify. If you’re on the fence about energy improvements, 2025 is the “now or never” window.

Keep These Documents

• Form 1098 (mortgage interest + escrowed taxes)
• Property tax bills + payment proof
• Closing disclosures showing deductible points
• Receipts/invoices for all improvements
• Manufacturer certifications for §25C items
• Form 5695 for energy credits
• MCC + Form 8396 if applicable

Good records = easier filing and safer audits.

Quick FAQ

What can a homeowner write off on taxes?
Mortgage interest, property taxes (subject to SALT limits), mortgage points, and some home-equity interest if used for home improvements. Credits may apply for energy upgrades or renewables.

Can I deduct home improvements?
Most improvements aren’t deductible right away, but they can increase your basis and lower capital gains later. Certain energy upgrades qualify for credits through 2025.

Are closing costs deductible?
Usually no — except certain items like mortgage points and property taxes paid at closing (if itemizing).

Do I automatically get a refund when I buy a home?
Not automatically. Buying a home can lower taxes, but whether you get a refund depends on your income, withholding, and total deductions/credits.

Bottom Line

Homeownership comes with real tax advantages — especially if you itemize or make qualifying energy upgrades. The biggest wins for most homeowners are mortgage interest and property taxes, while 2025 offers a last-chance opportunity for federal clean-energy credits. Pair that with smart documentation and timing, and your home can pay you back at tax time.
