Summary: Homeownership offers significant tax advantages, but many homeowners miss deductions by assuming they don’t itemize or forgetting less obvious benefits. From energy efficiency credits and home office expenses to property tax deductions and senior-specific breaks, this guide covers the most frequently overlooked opportunities that can reduce your tax burden and improve your household finances.
The tax advantages of homeownership are among the most significant benefits of owning a home. Yet every year, countless Americans leave money on the table—not because they don’t qualify for deductions, but because they don’t know the rules or assume they won’t benefit from itemizing. With the 2026 tax landscape shaped by the One Big Beautiful Bill Act and permanent changes to many provisions, it’s worth taking a fresh look at what you might be missing.
The Itemization Decision: Why It’s Worth the Math
One of the biggest mistakes homeowners make is automatically taking the standard deduction without calculating whether itemizing would save more. In 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly . If your itemized deductions—including mortgage interest, property taxes, charitable giving, and other eligible expenses—add up to more than these amounts, itemizing makes financial sense .
This is particularly relevant for homeowners early in their mortgage term. Mortgages are structured so that most of your monthly payment goes toward interest during the early years, making the mortgage interest deduction especially valuable . For example, if you have $50,000 in income and paid $8,000 in mortgage interest, you could be taxed on just $42,000—potentially saving $1,760 in the 22% bracket .
Mortgage Interest Deduction: Know the Limits
The mortgage interest deduction remains one of the most valuable tax benefits for homeowners. For 2026, you can deduct interest on up to $750,000 in mortgage debt for a primary residence and one second home . If you’re married filing separately, the limit is $375,000. For mortgages taken out before December 15, 2017, the limit is $1 million ($500,000 for married filing separately) .
Eligible properties include houses, condos, cooperatives, boats, and mobile homes that have sleeping, cooking, and toilet facilities . Most homeowners receive Form 1098 from their lender showing how much interest they paid during the year .
What About Mortgage Points and HELOCs?
Mortgage discount points may be deductible, though the rules are complex and worth discussing with a tax professional . Home equity loan and HELOC interest is deductible only if the funds were used to buy, build, or substantially improve the home securing the loan, and the combined limit of $750,000 applies .
Key 2026 Change: Mortgage Insurance Premiums
Mortgage insurance premiums became deductible again in 2026 after a period when they were not, with the deduction now made permanent . This applies to homeowners who put down less than 20% and pay private mortgage insurance. Income limits apply, so review your eligibility carefully.
Property Tax Deductions: State and Local Taxes
The IRS allows homeowners to deduct state and local real estate taxes, though it’s subject to a $40,000 limit ($20,000 if married filing separately) . This is part of the overall SALT deduction cap, which also includes state income taxes.
The SALT deduction cap was temporarily raised to $40,400 for 2026 ($20,400 for married filing separately) under the OBBBA, with phase-out beginning for those with modified adjusted gross income exceeding $505,000 . Starting in 2030, the cap reverts to $10,000 .
Personal Property Tax Deductions
Some states allow deductions for personal property taxes paid on vehicles, boats, and other tangible personal property. For example, a 2026 Missouri proposal would allow taxpayers to deduct 100% of tangible personal property taxes paid from their state adjusted gross income . Several states also offer deductions or credits for seniors based on property tax paid. These are often claimed on state returns and are frequently overlooked .
Energy Efficiency Credits: Home Improvements That Pay Back
Homeowners who made qualifying energy-efficient improvements may be eligible for significant tax credits. The Energy Efficient Home Improvement Credit allows 30% of costs for qualified energy efficiency improvements, with a $1,200 annual limit and specific per-item caps: $600 for windows, $250 per door (maximum $500 total), and $2,000 for heat pumps, heat pump water heaters, and biomass stoves .
Eligible improvements include insulation materials and systems, exterior windows, doors, and heating and cooling equipment that meet Energy Star or other efficiency standards . The original use of the component must begin with the taxpayer, and the improvement must reasonably be expected to remain in use for at least five years .
Qualified product identification numbers are required for specified property placed in service after December 31, 2024 . Keep manufacturer documentation to substantiate your credit claim.
Additional Energy Credits
Builders of energy-efficient homes may be eligible for the §45L credit of up to $5,000 per home for eligible dwelling units acquired before July 1, 2026 . Commercial property owners may benefit from Section 179D deductions worth up to $5.94 per square foot for energy-efficient improvements placed in service in 2026 .
Home Office Deductions: Not Just for Self-Employed
While the home office deduction is often associated with self-employed individuals and small business owners, it’s worth understanding the rules. For those who are self-employed or work from home as an employee, deductions may be available for the business use of a home.
For self-employed individuals, the home office deduction is claimed on Schedule C. Employees who work from home and incur additional expenses may have options through employer reimbursement arrangements.
Ministers and Military Housing Allowances
An often-overlooked provision applies to ministers and members of the uniformed services who receive a nontaxable housing allowance. The IRS explicitly allows these individuals to still deduct their real estate taxes and home mortgage interest—they don’t have to reduce their deductions based on the allowance .
What Homeowners Cannot Deduct
Understanding what is not deductible is equally important. The IRS is clear that homeowners cannot deduct the following :
- Homeowners insurance premiums
- Mortgage principal payments
- Wages paid to domestic help
- Depreciation (for personal residences)
- Utilities such as gas, electricity, or water
- Most settlement or closing costs
- Internet or Wi-Fi systems or service
- Homeowners’ association fees, condominium association fees, or common charges
- Forfeited deposits, down payments, or earnest money
- Home repairs (as opposed to improvements)
Senior-Specific Deductions
Homeowners aged 65 and older may qualify for additional deductions. A new “bonus” deduction of up to $6,000 per taxpayer over age 65 is available through 2028, subject to phase-out for those with modified adjusted gross income exceeding $75,000 ($150,000 for joint filers) . This is separate from the additional standard deduction seniors already receive.
Several states offer property tax deductions or freezes for seniors based on age, income, and residency requirements. These are typically claimed on state returns and are frequently overlooked .
Frequently Asked Questions
Can I deduct my property taxes if I take the standard deduction?

Can I deduct home office expenses as an employee?
For 2026, employees can generally no longer claim a deduction for unreimbursed home office expenses . However, some employers provide tax-free homeworking payments or reimbursements that may be available .

What happens if I sell my home after claiming energy efficiency credits?
If you claim an energy efficiency credit, your basis in the property is reduced by the amount of the credit . This can affect capital gains calculations when you eventually sell the home.
Making the Most of What’s Available
The single most valuable step homeowners can take is to gather all documentation before deciding whether to itemize or take the standard deduction. The decision isn’t permanent—you can choose each year based on what saves you more. Homeowners with significant mortgage interest, high property taxes, or major charitable contributions are often good candidates for itemizing, but the math changes each year based on your financial situation.
Understanding what is not deductible is equally important. This helps you avoid costly mistakes and focus on areas where the tax code offers real benefits. As you review your tax situation, consider whether you’ve overlooked energy credits, senior deductions, or the new mortgage insurance deduction. A few minutes of research could save you thousands.
Key Reflections
- The itemization decision isn’t automatic. With a $32,200 standard deduction for married couples, run the numbers each year to see which approach saves more.
- The mortgage interest deduction remains valuable. Early in the loan term, interest payments are largest, making this deduction particularly meaningful.
- Mortgage insurance premiums are deductible again. This applies to homeowners with PMI and is now permanently available.
- Energy efficiency credits are significant. The 30% credit covers insulation, windows, doors, heat pumps, and electrical panel upgrades.
- Senior deductions are often overlooked. Qualifying seniors can claim up to $6,000 ($12,000 joint) in additional deductions through 2028.
- Ministers and military housing allowance recipients can still claim full mortgage interest and property tax deductions.
- Property tax deductions vary by state. Check your state’s specific provisions for seniors, veterans, and homestead exemptions.
- Plan ahead for 2026 deadlines. The Section 45L credit for energy-efficient new homes expires for homes acquired after June 30, 2026.
