The state line runs through the middle of the Kansas City metro, and a short drive can take you from Kansas to Missouri. Both sides have established neighborhoods and new construction, and a common question is which side to buy on. Neither is better in general. What differs is specific and published: tax rates, how homes and cars are taxed, what new residents must do and what agents must disclose. This guide lays those out with each source and date. Rates and rules change, so check the date on each one. Tom Staats is licensed in both Kansas and Missouri, and the Moving to Kansas City guide is a good companion to this one.
One metro, two states
On the Kansas side are cities such as Overland Park, Leawood and Olathe. On the Missouri side are Kansas City, Missouri, Lee’s Summit and Blue Springs. The metro works as one connected region for work and daily life, and you can browse every city in the areas section.

What differs between the states
Income tax and the earnings tax
For 2026, Kansas taxes income at 5.2% on the first $23,000 of taxable income ($46,000 for married couples filing jointly) and 5.58% on the rest. Kansas law reviews state revenue each August 15 and lowers rates in years when the revenue tests are met.
Missouri’s graduated rates top out at 4.7%, which applies to taxable income above $9,436 in 2026. From the 2025 tax year, Missouri lets individuals subtract 100% of the capital gains they report on their federal return. Missouri voters decide Amendment 5 in November 2026; it would require the legislature to phase out the state income tax as revenue grows.
Kansas City, Missouri adds a 1% earnings tax. Everyone who lives in the city pays it on all earned income, and people who live elsewhere, including in Kansas, pay it on pay for work done inside the city. Voters renewed it on April 7, 2026. If you live in one state and work in the other, talk to a tax preparer about filing in both.
Property taxes
The two states start from different assessment rates. Kansas assesses homes at 11.5% of appraised value, and Johnson County revalues every property each year as of January 1. Missouri assesses homes at 19% of market value and reassesses real estate in odd-numbered years. On a $400,000 home, that is an assessed value of $46,000 in Kansas and $76,000 in Missouri.
The assessed value is only half of the bill. Each city, county, school district and other taxing unit sets its own levy, so a lower assessment does not by itself mean a lower tax. Kansas also exempts the first $75,000 of a home’s value from its 20-mill statewide school levy, worth about $172 a year. Compare the actual tax bills for the homes you are considering.
In Kansas, you generally have 30 days after the notice of value arrives to request an informal appeal. In Missouri, the county board of equalization hears appeals after an informal meeting with the assessor.
Sales tax
Kansas’s state sales tax is 6.5%, with a 0% state rate on qualifying food. From October 1, 2026, the combined rate in Overland Park is 9.35%, or 2.85% on qualifying food. Missouri’s state rate is 4.225%, and the combined rate in the Jackson County part of Kansas City is 8.975%, or 5.975% on food, for October to December 2026. Community improvement and transportation development districts add more in some shopping areas on both sides.
Cars and driver’s licenses
Kansas collects vehicle property tax with each registration and renewal, and the Kansas Department of Revenue’s lookup estimates it. New residents register within 90 days, after a Kansas Highway Patrol VIN inspection, and trade their driver’s license within 90 days.
Missouri counties tax vehicles owned on January 1 as personal property, assessed at 33 1/3% of value; in Jackson County the bill is due by December 31. New residents title their vehicles within 30 days and show a paid personal property tax receipt or a statement of non-assessment. The Missouri Driver Guide says a new resident needs a Missouri license to drive.
The buying process and paperwork
Both states license agents through their own commissions: the Kansas Real Estate Commission and the Missouri Real Estate Commission. In Kansas, K.S.A. 58-30,106 requires a seller’s agent to disclose to buyers all adverse material facts the agent actually knows, including the property’s physical condition and material defects. In Missouri, RSMo 339.730 covers facts the agent actually knows or should have known.
Missouri law also requires a seller to disclose in writing any methamphetamine production on the property they knew of (RSMo 442.606). Kansas law requires every contract for the sale of residential property to carry a notice about radon (K.S.A. 58-3078a, in effect since July 1, 2009). The notice says Kansas law requires sellers to disclose any information they know of that shows high radon concentrations in the home. In both states, federal law requires sellers of homes built before 1978 to disclose known lead-based paint and give buyers 10 days to inspect for it.
The seller’s disclosure form. The statutes above require specific disclosures, not a general form. The Kansas Real Estate Commission says it does not regulate what a seller must disclose and refers that question to an attorney. In the Kansas City area, the written disclosure comes from the contract. The Kansas City Regional Association of REALTORS standard sale contract (last revised October 2021) includes a Seller’s Disclosure and Condition of Property Addendum. In it, the seller confirms the disclosure is current and acknowledges that the law requires disclosure of known material defects. Ask for the seller’s written disclosure statement and read it alongside your inspection report.
Title insurance and closing. First American Title’s 2025 guide to state customs lists neither Kansas nor Missouri as an attorney state. It lists the owner’s title policy as negotiable in both and the lender’s policy as the buyer’s cost. Chicago Title’s Kansas City office says it is customary in the metro for the seller to buy the owner’s policy and for the buyer to pay for the lender’s policy, and the KCRAR standard contract has the seller provide and pay for the owner’s policy. Under that contract, closing is complete when the documents and funds have been delivered into escrow with the title company or other closing agent. Kansas licensees must give the buyer the approximate closing costs when an offer is written, and the seller when it is presented.
Transfer taxes. Neither state taxes the transfer of a home. First American lists no deed transfer tax and no mortgage tax in either state. Kansas repealed its mortgage registration tax from 2019, and a sales validation questionnaire goes with a deed when it is recorded. Missouri’s constitution has barred any new tax on the sale or transfer of real estate since November 2, 2010 (Article X, Section 25). Recording fees still apply.
These terms can be changed by agreement, so read the contract you sign and ask the title company for an estimate early.
Property tax relief
Kansas offers a homestead refund (Form K-40H) of up to $700 for owners who meet income and home value limits and another condition, such as being 55 or older or having a disability, and a separate SAFESR refund of 75% of property taxes for qualifying owners 65 and older. Missouri’s Property Tax Credit gives owners who are 65 or older or 100% disabled up to $1,100, based on income.
How to compare the right way
Rather than starting with which state is better, start with your own priorities and then look at the homes that fit them, wherever they are.
- Think about your commute and the places you go most often, and check whether a job is inside Kansas City, Missouri.
- Consider the type of home, lot and setting you want.
- Look at the full monthly cost of a specific home: the mortgage, that home’s tax bill, insurance and any homes association dues.
- If schools matter to you, look up the district by the exact address, since boundaries follow neither city nor state lines.
The home that best fits your needs and budget might be in Kansas or in Missouri. The buyer guide lays out the steps once you have found it.
Why a two-state agent helps
Real estate licenses are issued by each state’s commission, and not every agent holds both. Tom Staats holds licenses in both Kansas and Missouri, so one agent can show you homes across the metro and handle the contract in either state.
Getting the exact numbers
The rates above are the published ones. For a specific home, get a loan estimate from a lender, a settlement estimate from the title company and the property’s current tax bill from the county. A tax professional can show how income tax and the earnings tax apply to your household.
