Owning a home has always come with financial responsibilities, but it also comes with tax advantages that can meaningfully impact your long term wealth. While nobody should buy a house purely for tax breaks, understanding how to legally reduce your tax burden is part of smart financial strategy.

The One Big Beautiful Bill introduced several changes affecting homeowner tax deductions for the 2026 tax year, which taxpayers will file in 2027. Some deductions were expanded, some were tightened, and others disappeared entirely. With higher standard deductions expected to keep many taxpayers from itemizing, knowing which deductions still matter has never been more important.

Below are eight key homeowner tax deductions and rules to understand for 2026.

1. Mortgage Interest and PMI Deduction Returns

Mortgage interest remains one of the most valuable tax deductions available to homeowners. For 2026, private mortgage insurance premiums will once again qualify as deductible mortgage interest, reversing their exclusion from 2025 returns.

However, this benefit only applies if you itemize deductions instead of taking the standard deduction. With standard deduction levels still elevated, fewer homeowners may benefit unless their combined deductions exceed that threshold.

Taxpayers over age 65 also gain an additional deduction through 2028:

$6,000 for single filers
$12,000 for married couples filing jointly
Phases out above $75,000 single income or $150,000 joint

CPA John G. Adams explained the importance of itemizing in certain situations:

“If homeowners have a medical event and were in the hospital for three or four months, or they’ve given a significant amount of donations, all of those things fall into itemized categories. Mortgage interest is a component of it.”

For investors and higher income households, mortgage interest deductions can still provide meaningful tax relief when combined with other deductible expenses.

2. Home Equity Loan and HELOC Interest

Home equity loans and home equity lines of credit remain deductible in 2026, but only under strict conditions.

To qualify:

The borrowed funds must be used to buy, build, or improve your home
Total eligible mortgage debt is capped at $750,000 ($375,000 if married filing separately)
You must itemize deductions

Despite early expectations of looser rules, the OBBB kept restrictions largely intact. This means homeowners using equity for renovations or major upgrades may still benefit, but those using funds for unrelated expenses cannot deduct the interest.

For investors, home equity borrowing remains a common strategy to access capital, but tax benefits now require tighter compliance.

3. Mortgage Discount Points

Mortgage discount points remain deductible when purchasing or refinancing a home, assuming the homeowner itemizes.

Paying discount points reduces your mortgage rate. Roughly speaking, one point equals one percent of the loan value and can reduce your rate by about a quarter percentage point.

For example:

On a $400,000 mortgage, paying $4,000 in points could lower your rate from 7 percent to 6.75 percent

Tax educator Crystal Stranger warned homeowners to think long term:

“Just keep in mind that points are not financially smart unless you plan to live in your house at least five years before selling it.”

For long term homeowners, points can reduce both interest costs and tax liability.

4. Property Tax and the Expanded SALT Deduction

One of the biggest changes under the OBBB is the expansion of the SALT deduction cap.

The state and local tax deduction has been raised from $10,000 to $40,000 for 2026.

This is especially significant for homeowners in high tax states such as:

New York
California
New Jersey
Texas

However, the benefit begins phasing down for taxpayers earning more than $500,000 annually.

Crystal Stranger explained:

“This is great news for homeowners who pay high property taxes. However, earning more than that amount can actually have a more than dollar loss in credits and deductions for each increased dollar in income.”

For affluent households and real estate investors, the expanded SALT deduction could materially change after tax cash flow calculations.

5. HOA Fees Mostly Still Not Deductible

Homeowners association fees generally remain non deductible for primary residences.

There are limited exceptions, including:

Rental properties
Investment properties
Partial deduction for home offices

Most homeowners should not expect meaningful tax savings from HOA payments unless the property generates income.

6. Capital Improvements Increase Tax Basis

Home improvements do not usually create an immediate deduction, but they can reduce future capital gains taxes by increasing your home’s cost basis.

Eligible capital improvements include:

Major renovations
Structural upgrades
Additions that increase property value

Non qualifying expenses include:

Cosmetic changes
Routine maintenance
Minor repairs

Because capital gains taxes are triggered upon sale, homeowners planning long term ownership should keep detailed records of all improvements.

7. Home Office Deduction Still Available

Homeowners who use part of their home exclusively for business may still qualify for a home office deduction.

To qualify, the workspace must:

Be used regularly and exclusively for business
Be the primary place of business

The simplified deduction allows:

$5 per square foot
Maximum 300 square feet
Maximum deduction $1,500

Crystal Stranger noted:

“If you use your house for business, it opens the door to significantly more deductions, including a portion of repairs, utilities, and related expenses.”

This deduction primarily benefits self employed individuals, freelancers, and business owners.

8. Capital Gains Exclusion on Home Sales

Homeowners may avoid capital gains taxes when selling a primary residence if they meet two conditions:

The home was their primary residence
They lived in it for at least two of the past five years

The exclusion allows:

$250,000 tax free profit for single filers
$500,000 for married couples filing jointly

Example:

A married couple sells their home for $750,000 after purchasing it for $500,000.

Profit = $250,000
Exclusion = $500,000
Taxable gain = $0

Crystal Stranger noted:

“Capital gains taxes rarely are an issue for homeowners selling their primary residence.”

For investors and long term homeowners, this remains one of the most powerful tax benefits in real estate.

Expired Energy Tax Credits in 2026

Some previously popular energy related tax incentives are no longer available for property placed into service after December 31, 2025.

Expired credits include:

Energy Efficient Home Improvement Credit (25C)
Residential Clean Energy Credit for solar panels (25D)

This change could influence future home upgrade decisions and reduce incentives for solar installations unless new legislation restores these benefits.

Strategic Takeaway for Homeowners and Investors

Tax benefits should never be the sole reason to buy a home. As CPA John G. Adams put it:

“You should always be thinking strategically first about your family or business life. Taxes should be part of it, but it really should not be the deciding factor.”

Still, understanding homeowner deductions can:
