Kansas City Earnings Tax Explained: Who Pays the 1%, How Refunds Work, and Why It Shapes Where You Buy (2026)

If you're relocating to Kansas City and your new office is downtown, on the Plaza, or anywhere else inside the Kansas City, Missouri city limits, somebody has probably mentioned "the E-tax" already. It's a 1% tax on earnings, it's been around for decades, and it comes up in almost every conversation I have with buyers deciding between Johnson County, Kansas and the Missouri side.

Most of what people tell you about it is half right. This page covers what matters for a home decision: who pays it, what the April 2026 renewal decided, how the refund works if you work from home part of the week, and a worked example that puts the dollars next to the Kansas-versus-Missouri income-tax difference. If you want the bigger picture on Missouri's income-tax cuts, I wrote about that separately in Missouri's zero income tax plan and what it means for Kansas City real estate.

What the Earnings Tax Is

The Kansas City, Missouri earnings tax is a flat 1% tax on gross earnings: wages, salaries, commissions, and net profits from a business. It's a city tax, not a state tax, and it's separate from Missouri state income tax. St. Louis is the only other Missouri city that levies one, at the same 1% rate.

It's also the city's single largest revenue source. Reporting around the April 2026 vote put it at roughly 45% of Kansas City's general fund, around $373 million a year, and nearly half of that comes from people who don't live in the city. That last fact is the one that matters for you as a buyer.

Who Pays the 1% (and Who Doesn't)

Two groups pay the earnings tax:

• Residents of Kansas City, Missouri, on all of their earnings, no matter where they work. If you buy in Brookside and commute to a Corporate Woods office in Overland Park, you still owe the 1% on your full salary.
• Non-residents who work inside the KCMO city limits, on the earnings from work physically performed inside the city. If you buy in Leawood and go to a downtown office five days a week, you owe the 1% on that salary even though you never sleep in Missouri.

The people who don't pay it are non-residents who don't work inside the city. Live in Prairie Village and work in Lenexa? No earnings tax. Live in Overland Park and work fully remote for a Denver company? No earnings tax. Live in Olathe and work for a KCMO employer from your home office? You don't owe it on those days either, which is where the refund process comes in.

One thing that trips people up: "Kansas City" is a big place, but plenty of Missouri-side suburbs are separate cities. Lee's Summit, Independence, Raytown, Gladstone, Liberty, and Parkville are not Kansas City, Missouri, and their residents don't pay the earnings tax on residency alone. If you're looking at a Missouri-side home, check the actual taxing city, not the mailing address.

Employers in the city generally withhold the 1% for residents and non-residents alike. If yours doesn't, or you're self-employed, you file and pay it yourself with the city's Revenue Division.

The 2026 Renewal Vote and What Happens in 2031

Since 2010, Missouri law has required Kansas City and St. Louis to put their earnings taxes back on the ballot every five years. Kansas City voters approved it in 2011, in 2016, and again in 2021, when more than 77% voted yes.

The most recent renewal was April 7, 2026, and it passed with more than 75% of the vote. That keeps the tax in place through 2031, when it comes up again.

I bring this up because some relocation buyers assume the tax is on the verge of going away. It isn't. Plan your purchase around it being here, and treat any future repeal as a bonus, not a reason to pick a side of State Line Road.

How Refunds Work for Non-Residents

This is the part that's changed the most in the last few years, and the part most likely to be out of date on whatever forum thread you read. The basic rule: a non-resident only owes the earnings tax on days actually worked inside the city. If your employer withheld the full 1% but you worked some of those days at home in Kansas, on the road, or at a client site outside the city limits, you can request a refund for the out-of-city portion.

How you do it:

• File Form RD-109, the city's Wage Earner Return, along with Form RD-109NR, the non-resident schedule that allocates your wages by days worked inside versus outside the city.
• Attach documentation. The city expects proof of the out-of-city days. In practice that means a letter or email from your employer's HR or payroll team verifying your remote or travel days, and the form instructions also list things like calendars, travel logs, and time records as acceptable support.
• File by the federal income-tax deadline (normally April 15). A March 2022 ordinance ended the old five-year lookback for refund claims, and a follow-up ordinance in March 2023 set out the current process: return, non-resident schedule, and supporting documentation, all in by the federal deadline. If you file an extension with the city, you get an additional six months.
• Only working days count. Vacation, sick days, and holidays aren't days worked anywhere.

Two things before you count on a refund. It only helps non-residents; if you live inside KCMO, you owe the 1% on everything, remote or not. And it depends on your employer cooperating with the documentation, so ask HR how they handle KCMO earnings-tax verification before you decide a hybrid schedule makes the tax irrelevant.

A Worked Example: $250,000 Household Income

Assume a household with $250,000 in combined wages, one spouse working downtown in Kansas City, Missouri, and the family deciding between Leawood and Brookside. These are illustrations, not tax advice; your real numbers depend on deductions, filing status, and how income splits across the two states.

The earnings tax:

• 1% of $250,000 is $2,500 per year if all of that income is subject to the tax.
• Over ten years, that's $25,000, before raises.
• If the downtown spouse earns $150,000 and the other spouse works in Overland Park, only the $150,000 is taxed for a Johnson County household: $1,500 per year. For a Brookside household, the full $250,000 is taxed regardless of where either spouse works: $2,500 per year.
• If the downtown spouse works from a Leawood home office two days a week, a Johnson County household can file for a refund on roughly 40% of the withheld tax. The Brookside household can't.

The state income tax difference:

• For 2026, Kansas's top individual income-tax rate is 5.58%, which applies above $46,000 of taxable income for married couples filing jointly (the Tax Foundation's 2026 state rate tables are my source here).
• Missouri's top rate for 2026 is 4.7%, and it kicks in at a very low income threshold, so for a household at this level it's effectively a flat 4.7%.
• The gap is roughly 0.88 percentage points. On $250,000 of taxable income, that's about $2,200 per year, or $22,000 over ten years. Your real taxable income will be lower than gross after deductions, so the true gap is likely a bit smaller.

Here's the insight most people miss. If you work downtown full time, you pay the earnings tax on both sides of the state line, so it isn't a Kansas-versus-Missouri variable at all. The variable is state income tax, and Missouri wins that one by roughly $2,000 a year at this income.

It flips if you work in Johnson County or remotely. Then buying in KCMO adds a $2,500 tax you wouldn't otherwise owe, which roughly cancels Missouri's lower state rate. At a $250,000 income, the two effects land within a few hundred dollars of each other.

Johnson County vs. Kansas City, MO for a Downtown Commuter

If the earnings tax is a wash for a full-time downtown worker, what should drive the decision? The same things I tell every relocation client, in roughly this order.

Schools. Blue Valley and Shawnee Mission are the reason a lot of my buyers won't look east of State Line Road, and I understand that. If you're touring Leawood, Overland Park, or Prairie Village, you're mostly choosing among those two districts, and the school question tends to settle the state question before taxes ever come up.

Property taxes. Johnson County's effective property-tax rates typically run higher than Jackson County's on a comparable home. On a $750,000 house, that county difference can be a bigger annual number than the earnings tax. The cost-of-living breakdown for a Kansas City buyer puts the pieces side by side.

Commute. In my experience Leawood to downtown runs 20 to 25 minutes most mornings; Brookside is closer to 10 to 15, and Prairie Village sits in between. None are long, but if you're coming from Chicago or Dallas, a shorter drive has real value that never shows up on a tax form.

Resale. Johnson County's higher-end neighborhoods draw steady corporate-relocation demand, which helps when you eventually sell. That's an observation about who's buying, not a promise of appreciation.

Then taxes. By the time you've weighed the first four, the earnings tax is usually a footnote. The exception is a remote or Johnson County-based worker choosing KCMO for lifestyle reasons. For them it's a genuine, permanent 1% cost, and you should go in with your eyes open.

The Honest Case for the Missouri Side

I sell in Johnson County, but the Missouri side has real advantages and you should hear them from me.

• Brookside, Waldo, and the Plaza-adjacent neighborhoods offer walkable, older-home character that Johnson County mostly can't match. If you want a 1920s Tudor with a front porch and a coffee shop at the end of the block, that's KCMO.
• Price per square foot on the Missouri side is typically lower for comparable homes, though the gap narrows in the most desirable pockets.
• Missouri state income tax is lower, 4.7% versus Kansas's 5.58% top rate, and Missouri has been cutting.
• Missouri stopped taxing capital gains starting with the 2025 tax year. The Missouri Department of Revenue now allows a 100% subtraction of federally reported capital gains from Missouri adjusted gross income. If you expect a large gain on a business sale or investment, that's a material difference from Kansas, which taxes capital gains as ordinary income.

The caveats:

• Personal property tax. Both states tax your vehicles, but Missouri does it as a separate annual county bill, due December 31, based on what you owned on January 1. Kansas collects it at registration. The Missouri bill surprises relocation buyers every year, so budget for it.
• The earnings tax follows you. If you buy in KCMO, the 1% applies to your household's entire earnings no matter where either of you works, including a future job in Overland Park or a fully remote role.

Frequently Asked Questions

Do I pay the Kansas City earnings tax if I live in Leawood and work downtown?

Yes. Non-residents owe the 1% on wages for work performed inside the Kansas City, Missouri city limits, and your employer will usually withhold it. If you work some days outside the city, file Form RD-109 with the RD-109NR schedule and employer documentation to get a refund for those days.

Do I pay it if I live in Kansas City, Missouri but work in Kansas?

Yes. Residents owe the tax on all earnings regardless of where the work is done, with no refund based on work location.

How do I get a Kansas City earnings tax refund for remote work?

File Form RD-109 and Form RD-109NR by the federal tax deadline, typically April 15, with documentation of your days worked outside the city. An employer HR or payroll letter confirming remote days is the standard proof. The old five-year lookback is gone; claims are due by that deadline each year.

When does the Kansas City earnings tax come up for a vote again?

Voters renewed it on April 7, 2026 with more than 75% approval. Missouri law requires a vote every five years, so the next one is in 2031.
