Every Homeowner Tax Deduction You Can Claim in 2026

Tax season is here, and if you own a home, you are sitting on deductions that could save you hundreds — or even thousands — of dollars. The 2025 tax year (filing in 2026) brought several meaningful changes that directly benefit homeowners. The SALT deduction cap increased to $40,000, private mortgage insurance premiums became deductible again, and a brand-new deduction was introduced for homeowners 65 and older. This guide walks you through every deduction available, who qualifies, and how to make sure you are not leaving money on the table.

Standard Deduction vs. Itemizing: When Does It Pay Off?

Before diving into specific homeowner deductions, you need to answer one fundamental question: does itemizing actually save you more than the standard deduction? For 2025 (filing in 2026), the standard deduction amounts are:

You should itemize only if your total itemized deductions exceed the standard deduction for your filing status. If you bought your home recently and carry a large mortgage balance, or if you live in a high-tax state like California, New York, New Jersey, or Illinois, itemizing is more likely to benefit you.

1. Mortgage Interest Deduction

This is the heavyweight of homeowner tax breaks. You can deduct the interest you pay on mortgage debt up to $750,000 (or $375,000 if married filing separately). This limit applies to loans taken out after December 15, 2017. If your mortgage predates that cutoff, the old $1 million limit may still apply.

In practical terms, if you have a $400,000 mortgage at 6.5%, you are paying roughly $25,800 in interest during the first full year. That entire amount is deductible, which could reduce your taxable income significantly. Your lender sends you Form 1098 each January showing exactly how much mortgage interest you paid during the prior year.

2. State and Local Tax (SALT) Deduction — Now $40,000

The SALT deduction covers your state income tax (or state sales tax, if you prefer) plus local property taxes. For years, this deduction was capped at $10,000, which was a painful limit for homeowners in high-tax states who routinely paid $15,000 or more in property taxes alone.

Starting with the 2025 tax year, Congress raised the SALT cap to $40,000 for tax years 2025 through 2029. That is a massive relief for homeowners in states like New York, New Jersey, California, Connecticut, and Illinois where combined state income and property taxes frequently exceeded the old cap.

3. PMI Is Tax-Deductible Again

This one is a big deal for homeowners who put down less than 20%. Starting in 2026, private mortgage insurance (PMI) premiums — along with FHA mortgage insurance premiums (MIP), VA funding fees, and USDA guarantee fees — are once again treated as deductible mortgage interest.

If you are paying $150 per month in PMI on a conventional loan, that is $1,800 per year you can now add to your mortgage interest deduction when you itemize. The deduction was available on and off for years but had expired. Its return in 2026 is welcome news for millions of homeowners still carrying mortgage insurance.

4. New Senior Homeowner Deduction (Age 65+)

Beginning with the 2025 tax year, homeowners aged 65 and older may qualify for an additional federal deduction. This is designed to help seniors who own their homes outright (or have low mortgage balances) and might not otherwise have enough deductions to justify itemizing.

The specifics of the deduction amount and income thresholds vary, so check with your tax preparer or use the IRS Free File tools to determine your eligibility. If you are a senior homeowner, this is worth investigating — it could put real money back in your pocket even if your mortgage is paid off.

5. Property Tax Deduction

Your property taxes are deductible as part of the SALT deduction (section 2 above). Keep in mind that the deductible amount is what you actually paid during the tax year, not what was assessed. If your property tax bill was $8,000 but your escrow account disbursed $7,500 because of timing, you deduct $7,500.

6. Home Office Deduction (Self-Employed Only)

If you are self-employed and use a dedicated space in your home exclusively for business, you can deduct a portion of your housing costs. The simplified method allows $5 per square foot up to 300 square feet ($1,500 maximum). The regular method lets you deduct the actual percentage of your home used for business, including mortgage interest, utilities, insurance, and depreciation — but requires more detailed record-keeping.

Note: W-2 employees working from home cannot claim this deduction under current federal tax law, even if your employer requires remote work.

7. Energy-Efficient Home Improvement Credits

If you installed energy-efficient upgrades in 2025, you may qualify for the Residential Clean Energy Credit (up to 30% of costs for solar panels, solar water heaters, and geothermal heat pumps) or the Energy Efficient Home Improvement Credit (up to $3,200 per year for qualifying improvements like insulation, windows, doors, and heat pumps).

These are tax credits — not deductions — which means they reduce your tax bill dollar for dollar. A $2,000 credit saves you $2,000 in taxes, regardless of your tax bracket. That makes them far more valuable per dollar than deductions.
