Missouri Just Eliminated Capital Gains Tax: What KC Home Sellers Need to Know
By Emanuel Blando
Missouri now exempts individuals from state capital gains tax on home sale profits. Here's what KC-metro sellers need to know.
Does Missouri still tax capital gains when you sell your house?
No — as of 2025, Missouri became the first state in the country to fully exempt individual filers from state capital gains tax, including gains from a home sale. This only applies to Missouri-side sellers (Jackson, Cass, and Clay counties); Kansas has no equivalent law. Federal capital gains rules — including the $250,000/$500,000 primary-residence exclusion — are unchanged and still apply. Even the state's own guidance is inconsistent about which tax year the exemption starts with, so confirm the details with a CPA before you count on it.

Missouri sellers got a genuinely good piece of tax news this year, and most people I talk to in Lee's Summit, Waldo, and Brookside haven't heard about it yet.
In 2025, Missouri became the first state in the country to completely eliminate state-level capital gains tax for individual filers. If you sell your home — or any other asset — for a profit, Missouri no longer takes a cut of that gain on your state tax return. That's a real, meaningful change, and it's worth understanding before you list.
But there's a catch, and it's not a small one: even Missouri's own Department of Revenue publishes conflicting information about exactly when this kicks in. I'll walk you through what's solid, what's still murky, and who this actually changes things for.
What Actually Changed
House Bill 594, signed by Governor Mike Kehoe on July 10, 2025, lets individual Missouri taxpayers subtract 100% of their federally reported capital gains — short-term and long-term — from their Missouri taxable income. You claim it on Form MO-A alongside your regular MO-1040 return.
In plain terms: if you sell your Lee's Summit home for a $60,000 profit, Missouri no longer taxes that $60,000 at the state level. Before this law, Missouri taxed capital gains as ordinary income, same as your paycheck.
This applies to individuals only — not trusts, and not pass-through entities like most LLCs. And it only offsets gains; capital losses aren't eligible for this subtraction at all, so it doesn't help you claim a loss from elsewhere.
Missouri also still has no state, county, or city real estate transfer tax — a constitutional protection voters added back in 2010. Between that and this new capital gains exemption, Missouri has become one of the more seller-friendly states in the country from a tax standpoint.
The Catch: Even the State Isn't Fully Clear on the Timing
Here's what I tell every Missouri-side seller who asks me about this: read the fine print carefully, and don't assume you know your exact tax year without checking with a CPA.
Missouri's own Department of Revenue FAQ page on this subtraction contains two different answers to essentially the same question. One section says the subtraction is "effective for the 2025 tax year." Another section, a few questions down on that same page, says the subtraction "applies to tax years beginning on or after January 1, 2026" and that you can "first claim this on your 2026 individual income tax return, filed in 2027."
Those two statements don't agree with each other. I'm not going to guess which one is correct, and I'd encourage you not to either — this is exactly the kind of detail where you want a CPA or tax preparer looking at your specific closing date, not a blog post making a confident call on a question the state itself hasn't fully resolved. If you're selling this year and expecting a large capital gain, it's worth a phone call before you count on the exemption applying to your 2026 sale.
Who This Actually Matters For
Here's the part that surprises people: for most typical Kansas City-area home sales, this new law changes very little, because most sellers weren't going to owe capital gains tax anyway.
Federal law already lets you exclude up to $250,000 in gain if you're a single filer, or $500,000 if you're married filing jointly, on the sale of your primary residence — as long as you owned and lived in the home for at least two of the last five years. Those two years don't need to be back-to-back.
With the Kansas City metro's median sale price sitting around $345,000 to $401,000 in 2026, most sellers simply aren't generating enough profit to exceed that federal exclusion in the first place. If your gain falls under it, you weren't paying federal capital gains tax, and Missouri's new state exemption doesn't add anything on top of a bill that didn't exist.
Where this law actually moves the needle:
Longtime owners with significant appreciation. If you've owned your Brookside or South KC home for 20-plus years, your equity may have grown well past the federal exclusion threshold. That's where Missouri's exemption starts to matter in real dollars.
Inherited property that's appreciated since you inherited it. You get a stepped-up basis at inheritance, but if the home has continued gaining value since then, especially over several years, this can add up.
Luxury sales. If you're listing a $700,000-plus home in a premium Lee's Summit neighborhood, you're more likely to be working with gain above the federal exclusion.
Second homes and investment property. The federal $250K/$500K exclusion only applies to a primary residence. If you're selling a rental or a second home in Waldo or Verona Hills, you don't get that federal break at all — which means Missouri's state-level exemption is the only tax relief available to you on that sale.
If you fall into any of those categories, this is genuinely worth a real conversation with a tax professional before you set your listing price and your net-proceeds expectations.
If You're Selling in Overland Park, Prairie Village, or Leawood, This Doesn't Apply to You
I want to be direct about this because I've already had a couple of Kansas-side clients ask me about it after seeing headlines: this is a Missouri law. Kansas has not passed anything equivalent. If you're selling in Johnson County or Wyandotte County, your state capital gains treatment hasn't changed.
Kansas sellers are still working with the same rules as before — federal capital gains rules apply the same way on both sides of the state line, but there's no parallel state-level exemption on the Kansas side. If you're weighing whether to sell now, it's worth understanding what's actually driving your property tax numbers this year too — Johnson County held its mill levy flat for 2026, but rising appraised values are still pushing many bills higher, which is a separate cost question from anything discussed here.
What To Do With This Information
If you're on the Missouri side and sitting on a home with significant built-up equity, this is worth a real conversation — not because I can tell you your exact tax outcome (I can't, and neither can most blog posts), but because understanding your actual number changes how you think about timing, pricing, and whether now is the right moment to sell.
Every seller's tax situation is different, and the details here — your specific closing date, your basis, your filing status — are exactly the kind of thing a CPA needs to look at directly. What I can help with is the real estate side: what your home is actually worth today, how the current 2.4-month inventory environment affects your timeline, and what selling now versus waiting might mean for your bottom line.
Frequently Asked Questions
Does Missouri still tax capital gains on a home sale?
No — under Missouri's new law (HB 594), individual filers can subtract 100% of their federally reported capital gains, including gains from a home sale, from their Missouri taxable income. The state's own guidance is inconsistent about whether this starts with tax year 2025 or 2026, so confirm your specific tax year with a CPA.
Does this apply to sellers in Kansas too?
No. This is a Missouri state law only. It applies to sellers in Jackson, Cass, and Clay counties on the Missouri side of the metro. Kansas has not passed an equivalent law, so Johnson County and Wyandotte County sellers still follow the same rules as before.
Do I still owe federal capital gains tax when I sell my house?
Possibly, but most primary-residence sellers don't. You can exclude up to $250,000 in gain (single filer) or $500,000 (married filing jointly) if you owned and lived in the home for at least two of the last five years. Most Kansas City-metro home sales fall under this threshold entirely.
Who actually benefits from Missouri's new capital gains exemption?
It matters most for longtime owners with large equity gains, inherited property that has appreciated since inheritance, luxury home sales above $700,000, and second homes or investment property, which don't qualify for the federal primary-residence exclusion at all.
Should I wait to sell until I know exactly which tax year this applies to?
Not necessarily — that's a decision to make with a CPA based on your specific numbers, not a reason to delay a sale on its own. Market timing and tax timing are two different questions, and it's worth discussing both before you decide.
