A comprehensive guide to every homeowner tax deduction available in 2026 — from mortgage interest and property taxes to energy credits and the home office deduction.
Here's something that drives me crazy: millions of homeowners leave thousands of dollars on the table every single tax season because they don't know about all the deductions they're entitled to. And honestly? The tax code doesn't make it easy. It's a maze of rules, phase-outs, income limits, and forms that would confuse even the most diligent filer.
But here's the good news — if you own a home, the IRS actually gives you a pretty generous set of tax breaks. We're talking about deductions and credits that can save you anywhere from a few hundred to tens of thousands of dollars a year. The trick is knowing what's available and making sure you're taking advantage of every single one.
In this guide, we'll walk through every major homeowner tax deduction and credit for 2026, explain exactly how each one works, and give you the numbers so you can estimate your own savings. Grab a cup of coffee — this one's worth reading all the way through.
The Big One: Mortgage Interest Deduction
If you have a mortgage, the mortgage interest deduction is probably your single biggest tax break. It allows you to deduct the interest you pay on your mortgage from your taxable income, and for most homeowners, that's a substantial amount — especially in the early years of a loan when your payments are mostly interest.
How It Works in 2026
For mortgages taken out after December 15, 2017, you can deduct interest on up to $750,000 of mortgage debt ($375,000 if married filing separately). If your mortgage is from before that date, the old limit of $1,000,000 ($500,000 if married filing separately) still applies to you — so don't let anyone tell you otherwise. Both figures come straight from the IRS (IRS Publication 936, "Home Mortgage Interest Deduction").
Let's put some real numbers on this. Say you have a $400,000 mortgage at 6.5% interest. In your first year, you'll pay roughly $25,800 in interest. If you're in the 24% tax bracket, that deduction saves you about $6,192 in federal taxes. That's real money.
Pro tip: Your mortgage servicer sends you Form 1098 every January, which shows exactly how much interest you paid during the year. Make sure the amount matches your records, and keep the form with your tax documents.

Does the Mortgage Interest Deduction Still Make Sense?
Here's the thing — since the standard deduction was nearly doubled in 2018, fewer homeowners actually benefit from itemizing. For tax year 2026 the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly (IRS, "Tax inflation adjustments for tax year 2026"). You only benefit from the mortgage interest deduction if your total itemized deductions exceed that number.
For many homeowners with smaller mortgages, the standard deduction might actually be the better deal. But if you have a larger mortgage, property taxes, state income taxes, and charitable donations, itemizing can still save you significantly more.
Property Tax Deduction (and the SALT Cap)
You can deduct the property taxes you pay on your home, but the deduction is capped. The SALT cap (State and Local Tax deduction) limits your combined deduction for state income taxes (or sales taxes) AND property taxes. That cap used to be $10,000 — it is not any more. Public Law 119-21 raised it to $40,000 ($20,000 if married filing separately), and the IRS states the limit is "reduced if your modified adjusted gross income is more than $500,000 ($250,000 if married filing separately) but will not be reduced below $10,000 ($5,000 if married filing separately)" (IRS Publication 530, "Tax Information for Homeowners").
What This Means in Practice
If you live in Texas and pay $8,000 in property taxes with no state income tax, you deduct the full $8,000 — nowhere near the cap. The change matters most in high-tax states: a New Jersey household paying $12,000 in property taxes plus $8,000 in state income tax has $20,000 of SALT, all of which is now deductible if income is under the phase-down threshold. Under the old $10,000 cap, half of it was lost.

Watch the Income Phase-Down
The higher cap is not unconditional. Above $500,000 of modified adjusted gross income ($250,000 if married filing separately) the $40,000 allowance shrinks, and the floor it shrinks toward is the old $10,000. If your income is near that threshold, the SALT figure you can actually claim is a calculation, not a flat number — the IRS points to the Instructions for Schedule A (Form 1040) for the mechanics.
Home Office Deduction
If you use part of your home exclusively and regularly for business, you may be able to claim the home office deduction. This has become a much bigger deal since remote work became the norm, but there are strict rules you need to follow.
Who Qualifies?
Here's the important caveat: W-2 employees cannot claim the home office deduction, even if they work from home full-time. This deduction is only available to self-employed individuals, freelancers, independent contractors, and business owners. If you receive a W-2, you're out of luck on this one.
Two Methods for Calculating
Simplified method: Deduct $5 per square foot of your home office, up to 300 square feet. Maximum deduction: $1,500. It's easy, but you might be leaving money on the table.
Regular method: Calculate the actual expenses of your home office based on the percentage of your home used for business. If your office is 200 sq ft in a 2,000 sq ft home, that's 10% — so you can deduct 10% of your mortgage interest, property taxes, utilities, insurance, repairs, and depreciation.
- Your office space must be used exclusively for business — a corner of the living room where the kids also do homework doesn't count
- It must be your principal place of business or a place where you regularly meet clients
- Keep records of all home expenses and measurements
- The regular method often provides a larger deduction but requires more documentation
Energy Efficiency Tax Credits (Sections 25C and 25D): Both Ended After 2025
If you have read older guides promising generous federal credits for energy upgrades, that window has closed. Public Law 119-21, enacted July 4, 2025, terminated both residential energy credits years earlier than the Inflation Reduction Act had scheduled:
- Section 25C (Energy Efficient Home Improvement) is not allowed for property placed in service after December 31, 2025.
- Section 25D (Residential Clean Energy — solar, battery storage, geothermal, small wind) is not allowed for expenditures made after December 31, 2025. An expenditure counts as made when the installation is completed, so a system finished in 2026 does not qualify no matter when you signed or paid a deposit.
See the IRS guidance on the accelerated termination of these provisions and its home energy tax credits page.
The rest of this section describes what the credits covered, because it still matters for one group of readers: if your work was completed in 2025 or earlier and you have not yet filed, you can still claim it on that year's return.
Section 25C: Energy Efficient Home Improvement Credit (through 2025 only)
For property placed in service through December 31, 2025, this credit covered upgrades to an existing home and was worth up to $3,200 per year — claimable annually as long as you kept making qualifying improvements.
| Improvement | Credit Amount | Annual Limit |
|---|
| Heat pumps (air source) | 30% of cost | $2,000 |
| Heat pump water heaters | 30% of cost | $2,000 |
| Biomass stoves/boilers | 30% of cost | $2,000 |
| Central AC, furnaces, boilers | 30% of cost | $600 each |
| Insulation and air sealing | 30% of cost | $1,200 |
| Windows and skylights | 30% of cost | $600 |
| Exterior doors | 30% of cost | $250 per door ($500 total) |
| Energy audit | 30% of cost | $150 |
| Electrical panel upgrade | 30% of cost | $600 |
The overall annual limit was $1,200 for most improvements, with a separate $2,000 limit for heat pumps and biomass stoves — up to $3,200 total in a single year. Those limits applied per tax year, so a 2025 project claimed on your 2025 return still uses them.
Section 25D: Residential Clean Energy Credit (through 2025 only)
For expenditures made through December 31, 2025, solar panels, solar water heaters, battery storage, geothermal heat pumps and small wind turbines earned a credit worth 30% of the total cost with no annual cap. A $25,000 solar installation completed in 2025 was a $7,500 credit.
If you are planning an installation now: budget the full cost. A $30,000 solar system plus a $12,000 battery finished in 2026 earns no federal credit — the $12,600 that the same project would have returned in 2025 is simply gone. State incentives, utility rebates and net metering still apply where your state offers them, and they are what determines payback now.
Capital Gains Exclusion When You Sell
This isn't technically a deduction you claim every year, but it's one of the most valuable tax benefits of homeownership. When you sell your primary residence, the IRS says you "may qualify to exclude up to $250,000 of that gain from your income, or up to $500,000 of that gain if you file a joint return with your spouse" (IRS Topic No. 701, "Sale of your home"). You have to pass the ownership and use tests — 24 months of each out of the five years before the sale — to get there.
Qualifying Rules
- You must have owned the home for at least 2 of the last 5 years
- You must have lived in the home as your primary residence for at least 2 of the last 5 years
- You can't have used this exclusion in the last 2 years
So if you bought a home for $350,000 and sell it for $550,000, your $200,000 gain is completely tax-free. For a married couple, you'd need gains above $500,000 before you owe any capital gains tax. That's an enormous benefit that renters simply don't get.
Points Deduction
When you took out your mortgage, you might have paid "points" — essentially prepaid interest to get a lower rate. Each point costs 1% of your loan amount. The good news: those points are deductible.
When You Can Deduct Points
Purchase mortgage: You can deduct the full amount of points in the year you paid them, as long as the loan is for your primary residence and paying points is customary in your area (which it is in most of the US).
Refinance: Points paid on a refinance must be deducted over the life of the loan. So if you paid $4,000 in points on a 30-year refinance, you'd deduct $133.33 per year. However, if you refinance again or sell the home, you can deduct any remaining un-deducted points in that year.

PMI Deduction
Private Mortgage Insurance — the extra cost you pay when your down payment is less than 20% — has had an on-again, off-again relationship with tax deductibility, and right now it is mid-swing. The IRS's current guidance still carries the reminder that "the itemized deduction for mortgage insurance premiums has expired. You can no longer claim the deduction" (IRS Publication 936) — that is the status for returns covering 2022 through 2025. Public Law 119-21 restores the treatment of qualified mortgage insurance premiums as residence interest for tax years beginning after 2025, so it should be claimable on the 2026 return you file in 2027.
Income Limits, and Why You Should Confirm Before Counting On It
The deduction has historically phased out starting around $100,000 of adjusted gross income ($50,000 married filing separately) and disappeared entirely a little above that. Because the IRS has not yet reissued Publication 936 for the restored version of this deduction, treat the exact phase-out band as unsettled and check the 2026 instructions — or ask your preparer — before you plan around it. This is our reading of a statute the IRS has not finished writing guidance for, not a figure we can point you at a published table for.
If you're currently paying PMI, a better long-term strategy is to build equity and get rid of it entirely. Use our mortgage calculator to see when you'll hit the 80% loan-to-value ratio where you can request PMI removal.

Deductions You Can't Claim (Even Though People Try)
Let's clear up some common misconceptions. These are NOT deductible, no matter what your neighbor told you at the barbecue:
- HOA fees — Not deductible for your primary residence (may be partially deductible for rental properties)
- Home repairs — Fixing a leaky faucet or replacing a broken window is considered maintenance, not a deduction. However, improvements that increase your home's value can be added to your cost basis when you sell.
- Homeowners insurance — Not deductible for your primary residence
- Utilities — Not deductible (unless you qualify for the home office deduction)
- Moving expenses — No longer deductible for most taxpayers (military members are the exception)
- Landscaping and lawn care — Nope, even if it increases your home's value
Strategies to Maximize Your Tax Savings
1. Bundle Your Deductions
If you're close to the standard deduction threshold, consider "bunching" deductible expenses into one year. For example, make your January mortgage payment in December (paying an extra month's interest in the current tax year), prepay property taxes, and make charitable donations all in the same year.
2. Track Home Improvements
While home improvements aren't directly deductible, they increase your home's cost basis — which reduces your capital gains when you sell. Keep receipts for every improvement project, no matter how small. Over 10-20 years of ownership, these can add up to significant tax savings at sale time.
3. Energy Credits No Longer Reward Timing
This used to be the section where we told you to spread energy improvements across several years, because the 25C credit reset annually — heat pump one year, windows the next, insulation after that. That strategy died with the credit. For work placed in service after December 31, 2025 there is nothing to spread, so sequence projects by what actually saves you money on the utility bill or prevents a failure, not by tax year. If a project was finished in 2025 and you have not filed yet, that one still belongs on your 2025 return.
4. Don't Forget State Deductions
Many states offer their own homeowner tax deductions and credits beyond what the federal government provides. Some states offer mortgage credit certificates, property tax relief programs, first-time homebuyer credits, or additional energy efficiency incentives. Check with your state's tax authority or a local CPA.
When to Hire a Tax Professional
While many homeowners can handle their own taxes with good software, there are situations where a professional is worth the investment:
- You bought or sold a home during the tax year
- You have rental property income or a home office
- You made significant energy efficiency improvements
- Your itemized deductions are close to the standard deduction threshold
- You have a complex situation (divorce, inheritance, multiple properties)
A good CPA or enrolled agent typically charges $200–$500 for a homeowner tax return and can often find enough additional deductions to more than cover their fee.
The Bottom Line
Homeownership comes with real, substantial tax benefits — but only if you know about them and take the time to claim them. The mortgage interest deduction, property tax deduction, energy credits, and capital gains exclusion alone can save a typical homeowner thousands of dollars every year.
Start by running your numbers through our mortgage calculator to see your interest breakdown, review our property tax guide to understand your SALT situation, and keep meticulous records of every improvement you make. When April rolls around, you'll be glad you did.
