Tax Benefits of
Homeownership
Owning a home comes with significant tax advantages that can save you thousands of dollars each year. Here is every deduction and credit you need to know.
Last updated: March 2026
Mortgage Interest Deduction
How It Works
You can deduct the interest paid on mortgage debt up to $750,000 for homes purchased after December 15, 2017 (or $1,000,000 for mortgages originating before that date). This applies to your primary residence and one additional home.
The deduction is available if you itemize deductions on your federal tax return (Schedule A). For most homeowners in California, the combination of mortgage interest and state/local taxes makes itemizing worthwhile.
Real Example
$570,000 loan at 6.75% (30-year fixed)
That is $1,060/month in tax savings, effectively reducing your mortgage cost.
Property Tax Deduction
What You Can Deduct
Property taxes paid on your home are deductible as part of the State and Local Tax (SALT) deduction. The SALT deduction is capped at $10,000 total ($5,000 if married filing separately), which includes state income taxes, property taxes, and local taxes combined.
- Up to $10,000 SALT deduction cap
- Includes property tax + state income tax
- Applies to primary and second homes
- Must itemize to claim
California Impact
California homeowners often hit the $10,000 SALT cap quickly due to the combination of property taxes (typically 1.1%–1.3% in LA County) and California's high state income tax rates (up to 13.3%).
- $600K home = ~$7,500/yr in property tax
- State income tax takes the rest of the $10K cap
- Still a significant deduction at any income level
- Potential SALT cap increase being discussed in Congress
Capital Gains Exclusion
One of the most powerful tax benefits in the entire tax code is available exclusively to homeowners.
The Section 121 Exclusion
When you sell your primary residence, you can exclude up to $250,000 (single) or $500,000 (married filing jointly) in capital gains from your taxable income. This is entirely tax-free profit.
To qualify, you must have owned and used the home as your primary residence for at least 2 of the 5 years before the sale. You can use this exclusion repeatedly, but generally only once every 2 years.
Real-World Impact
Bought at $600K, sold at $900K after 7 years (married)
Without the exclusion, this gain would be taxed at 15%–20% federal plus 9.3% California.
Home Office Deduction
Who Qualifies
If you are self-employed or an independent contractor who uses part of your home regularly and exclusively for business, you may qualify for the home office deduction. This deduction is not available to traditional W-2 employees.
- ✓ Self-employed individuals
- ✓ Independent contractors (1099)
- ✓ Small business owners
- ✓ Freelancers and gig workers
Two Calculation Methods
Simplified Method
$5 per square foot, up to 300 sq ft = maximum $1,500 deduction. Easy to calculate, no detailed records needed.
Regular Method
Deduct a percentage of your actual home expenses (mortgage interest, property tax, insurance, utilities, repairs, depreciation) based on the square footage of your office relative to your home. Often yields a larger deduction.
Energy Efficiency Tax Credits
Homeowners can claim tax credits for making energy-efficient improvements to their homes.
Residential Clean Energy Credit
A 30% tax credit for solar panels, solar water heaters, geothermal heat pumps, small wind turbines, and fuel cell property through 2032.

- Pairs well with solar panels
Additional Tax Advantages
Points Deduction
Discount points paid at closing to lower your interest rate are deductible in the year paid (for purchase loans) or amortized over the life of the loan (for refinances). Each point equals 1% of the loan amount.
PMI Deduction
Private mortgage insurance premiums may be tax-deductible depending on your adjusted gross income and current tax law. This deduction has been extended and expired multiple times — check with your tax advisor for current status.
Rental Income
If you rent out part of your home or a secondary property, you can deduct expenses related to the rental portion including depreciation, repairs, insurance, and management costs. This can create tax-advantaged income streams.
1031 Exchange (Investment)
Investment property owners can defer capital gains taxes indefinitely by exchanging one property for another of equal or greater value using a 1031 exchange. This allows continuous reinvestment without tax drag.
