Tax Deductions Every Homeowner Should Know in 2026
Owning a home comes with valuable tax benefits that many homeowners overlook. Knowing which deductions and credits you qualify for can save you thousands of dollars each year — but the rules changed in recent years, and not everyone benefits equally. Here are the key items to keep on your radar in 2026, plus the one decision that determines whether any of them matter for you.
First: Itemize or Take the Standard Deduction?
This is the make-or-break question. Homeowner deductions like mortgage interest only help if your total itemized deductions exceed the standard deduction for your filing status. Since the standard deduction was nearly doubled in 2018, the majority of homeowners now take it and skip itemizing entirely.
Before counting on any deduction below, add up your mortgage interest, property taxes, and other itemizable expenses, then compare that total to your standard deduction. If itemizing wins, the following deductions come into play.
1. Mortgage Interest Deduction
One of the largest tax breaks for homeowners. You can generally deduct interest paid on mortgage debt used to buy, build, or substantially improve your primary or secondary home. For loans taken after December 15, 2017, the deduction applies to interest on up to $750,000 of mortgage debt ($375,000 if married filing separately). Older loans may be grandfathered under the previous $1 million limit.
2. Property Tax Deduction
State and local property taxes are deductible, but they fall under the SALT (State and Local Tax) cap — currently limited to $10,000 per year combined for most filers ($5,000 if married filing separately). In high-tax states, homeowners often hit this cap quickly.
3. Home Office Deduction
If you use part of your home exclusively and regularly for business, you may deduct related expenses — a valuable benefit for the self-employed and independent contractors. Note that under current federal rules, W-2 employees working remotely generally cannot claim this deduction. There are two methods:
| Method | How it works | Best for |
|---|---|---|
| Simplified | $5 per sq ft, up to 300 sq ft ($1,500 max) | Easy record-keeping |
| Regular | Actual % of home expenses (utilities, insurance, etc.) | Larger offices / higher costs |
4. Energy-Efficient Home Improvements
These often qualify for federal tax credits — which reduce your tax bill dollar-for-dollar, making them even more valuable than deductions. Common qualifying upgrades include:
- Solar panels and solar water heaters
- Energy-efficient windows and doors
- Qualifying heating and cooling (HVAC) systems
- Insulation and energy-efficient roofing
Tip: Keep detailed records and receipts for all home-related expenses. Proper documentation is essential if the IRS ever requests proof of your deductions or credits.
5. Points Paid on Your Mortgage
If you paid discount points to lower your interest rate when buying or refinancing, those points may be deductible — sometimes fully in the year paid (typical for a home purchase), and sometimes spread over the life of the loan (common for refinances). The rules depend on how and why you paid them.

Frequently Asked Questions
