Tax Deductions for Homeowners: Kansas City 2026 Guide
Most homeowners miss two of these. One of them matters most the year you sell.
The tax rules for homeowners changed in a big way for 2026. Some breaks got bigger. One came back from the dead. Another disappeared completely. If you own a home in Kansas City, the list of tax deductions for homeowners you can actually use looks different this year than it did two years ago.
I'm Jason DeLong with Heartland Homes KC. I've built over 100 homes and flipped over 150 homes personally, so I know a thing or two about the process. That includes the paperwork side. I've seen how much money owners leave on the table simply because they didn't keep the right records.
This guide breaks down what Kansas City owners can claim for 2026, what you can't, and the one habit that can save you thousands when you sell. If you're thinking about selling in the next year or two and want to map out your net, schedule a quick call with me here.
One quick note before we start. I'm a Kansas City real estate agent and investor, not a CPA. Use this as a game plan, then confirm the details with your tax pro.
First Question: Will You Itemize or Take the Standard Deduction?

Every homeowner deduction below hinges on this one decision.
For 2026, the standard deduction is $32,200 for married couples filing jointly and $16,100 for single filers. Most of the homeowner deductions in this post only help you if your itemized total beats that number.
For years, that was hard to do. The old $10,000 cap on state and local taxes kept a lot of Kansas City families stuck on the standard deduction. That changed in 2026.
Here's a simple illustration. A married couple has a $350,000 mortgage at 6.5%. In year one, they pay roughly $22,600 in interest. They also pay $5,000 in property tax and $8,000 in Missouri income tax.
Mortgage interest: about $22,600
State and local taxes: $13,000
Total itemized: about $35,600
That beats the $32,200 standard deduction by roughly $3,400. Under the old $10,000 cap, they would have barely cleared it. Run your own numbers before you assume the standard deduction wins.
Mortgage Interest Deduction 2026: What Kansas City Owners Can Claim
The mortgage interest deduction is still the biggest line item for most owners.
For 2026, you can deduct interest on up to $750,000 of mortgage debt used to buy, build, or substantially improve your main home or a second home. That limit is now permanent. Loans taken out before December 16, 2017 keep the older $1 million limit.
A few details owners often miss:
Points you paid at closing on a purchase loan are usually deductible.
Home equity loan or HELOC interest only counts if you used the money to buy, build, or substantially improve the home. Paying off credit cards with a HELOC does not qualify.
In the year you sell, you can deduct the interest you paid up to the closing date.
The Comeback Deduction: PMI Is Deductible Again
This is the first deduction most homeowners will miss.
Private mortgage insurance premiums are deductible again starting in 2026. The break had expired after 2021. Now PMI is treated as deductible mortgage interest.
There are limits. The benefit starts phasing out once your adjusted gross income passes $100,000. FHA mortgage insurance is handled differently, so check with your CPA if you have an FHA loan.
Why does this matter in Kansas City? A lot of first-time buyers here put less than 20% down. That means a lot of local homeowners are paying PMI right now and may not know it's deductible again.
Property Tax Deduction Limit: The Big 2026 Change

The property tax deduction limit is the headline change this year.
Property taxes fall under the SALT deduction, which stands for state and local taxes. That bucket includes your property taxes plus your state income tax.
For 2026, the SALT cap is $40,400. That's up from $10,000 just two years ago. The cap rises 1% each year through 2029. Then it is scheduled to drop back to $10,000 in 2030.
High earners get less of the benefit. The cap starts shrinking once modified adjusted gross income passes $505,000.
What This Means on Both Sides of State Line
Kansas City is a two-state market, and your SALT math depends on which side you live on.
Missouri side owners combine property taxes with Missouri income tax. Kansas City, Missouri residents should also ask their CPA how the city earnings tax fits into the picture.
Kansas side owners in Johnson County and Wyandotte County combine property taxes with Kansas income tax.
Either way, a $40,400 cap covers most Kansas City households completely. If you were capped at $10,000 before, this alone may flip you from the standard deduction to itemizing.
Is Home Improvement Tax Deductible?
This is the most common question I get from homeowners. The honest answer is no, not in the year you do the work.
A new kitchen, a finished basement, or a new roof on your personal residence is not a deduction on this year's return. But that does not mean the money disappears. It goes somewhere much more valuable, which I'll explain in the next section.
There are a few exceptions where improvement costs can help sooner:
Medical modifications like ramps, wider doorways, or accessible bathrooms can count as medical expenses. Those only help once your medical costs pass 7.5% of your adjusted gross income.
Home office space can be deductible if you're self-employed and use the space regularly and exclusively for business. W-2 employees working from home do not qualify.
Rental space, like a basement apartment or a short-term rental, can make a portion of costs deductible as a business expense.
Energy Credits Are Gone for 2026
If you were planning solar panels, a heat pump, or new windows for a tax credit, I have bad news. The federal energy efficient home improvement credit and the residential clean energy credit both ended on December 31, 2025.
Projects finished and placed in service in 2025 can still be claimed on your 2025 return. If you filed an extension, your deadline is October 15, 2026. Make sure your CPA has those receipts.
The Deduction That Matters Most the Year You Sell

This is the second thing most homeowners miss. And it's the one that can cost you real money.
It's not technically a deduction. It's your cost basis. Every dollar of capital improvement you put into your home gets added to what you paid for it. When you sell, that higher basis shrinks your taxable profit.
From my builder and investor side, I treat every rehab like it will get audited. On a flip, the receipt file matters as much as the rehab budget. Homeowners should run their house the same way.
Repairs vs. Improvements: Know the Difference
Not everything you spend counts toward basis.
Improvements that add to basis include:
A new roof
Kitchen or bath remodels
Finished basements or additions
New HVAC, water heater, or electrical upgrades
Decks, fencing, and landscaping projects
Replacement windows and siding
Repairs that generally do not count include:
Patching drywall
Repainting a room
Fixing a leaky faucet
Replacing a broken window pane
Keep receipts, contracts, and photos for every improvement. Store them in one folder for as long as you own the home, plus a few years after you sell.
Capital Gains Exclusion on a Home Sale
The capital gains exclusion on a home sale is the biggest tax break most owners will ever use.
If you owned and lived in the home as your main residence for at least two of the last five years, you can exclude up to $250,000 of profit if you're single. Married couples filing jointly can exclude up to $500,000.
That number has not changed since 1997. Meanwhile, home values across Kansas City neighborhoods have climbed a lot. Long-time owners in some of the best neighborhoods in Kansas City are now closer to that ceiling than they realize.
Here's How Basis Records Change the Math
A hypothetical example. A single owner bought a home for $280,000. Over the years, they put $60,000 into a new roof, a kitchen remodel, and a finished basement. They sell for $650,000.
Without improvement records: $370,000 gain, minus $250,000 exclusion, leaves $120,000 taxable.
With improvement records: $310,000 gain, minus $250,000 exclusion, leaves $60,000 taxable.
At a 15% federal capital gains rate, that's the difference between about $18,000 in tax and about $9,000. Same house. Same sale price. The only difference is a folder of receipts.
Selling costs also reduce your gain. Agent commissions, title fees, and certain closing costs all lower the amount you realized from the sale.
Missouri Sellers Got a Big Break
Missouri eliminated its state income tax on capital gains for individuals starting with the 2025 tax year. That applies to profit from selling a home, regardless of how long you owned it.
If you sell a home on the Missouri side, federal rules still apply. But the state no longer takes a cut of your gain. Kansas side sellers should confirm their state treatment with a CPA, because the Missouri exemption does not cross State Line.
What If You Haven't Lived There Two Years?
You may still qualify for a partial exclusion if you sold because of a job change, a health issue, or certain unforeseen circumstances. Talk to your tax pro before you list if you're under the two-year mark. Timing your closing by even a few weeks can matter.
How This Fits Into a Smart Selling Strategy

At Heartland Homes KC, we start every seller conversation with one goal: maximize your net, not just your price.
Taxes are part of that net. So is the path you choose to sell. Some sellers want a fast close. Some want to put money into the house first and sell for more. Some need to buy their next home before they sell this one.
That's why we offer multiple options instead of one path:
Cash Offers+ gives you a market-value cash offer with a fast close. You can request cash offers on your home here and compare them against a traditional sale. If you've been searching for cash home buyers Kansas City owners can trust, this lets you see real numbers side by side.
Fix It & List It covers repairs and upgrades with no upfront cost from you.
Our Trade-In Program lets you buy first and sell later.
When we list a home, we use our 100+ Point Marketing Plan to build demand before the home ever hits the market.
Not sure where you stand on gain? Start by checking your home's current value. Then subtract your purchase price and improvements. That gives you a rough idea of whether the exclusion covers you.
If you're also shopping for your next home, browse our featured listings across Kansas City neighborhoods to see what's available right now.
