Credit card processing and merchant services in Kansas City, KS
Kansas City, Kansas sits on the Wyandotte County side of the state line, so businesses here follow Kansas surcharge and sales tax law, not Missouri's.
This page covers Kansas City, Kansas, in Wyandotte County. If your business is across the state line in Kansas City, Missouri, our Kansas City, Missouri page is the one you want, because the two cities follow different state laws. They differ in size, too: the Census Bureau's July 1, 2025 estimates put Kansas City, Kansas at 157,805 people and Kansas City, Missouri at 521,220.
The state line changes how you surcharge. In Kansas, K.S.A. 16a-2-403 has allowed credit card surcharges since January 1, 2025, on one condition: you disclose the amount in a clear and conspicuous notice at the point of entry or point of sale before the customer pays. Missouri has no surcharge statute at all. Kansas sets no cap of its own, so Visa's 3% and Mastercard's 4% are the ceilings, and debit cards can't be surcharged on either side.
Groceries follow a Kansas rule too. The state tax on food and food ingredients dropped to 0% on January 1, 2025, and prepared food still carries the full 6.5% state rate. Local sales taxes are a separate matter, so find out how they treat food at your address before you set up POS terminals.
Your combined rate is the state's 6.5% plus the local taxes at your address, so look it up with the Kansas Department of Revenue instead of borrowing a number from another store. Kansas moves local rates only four times a year, on January 1, April 1, July 1 and October 1, with at least 60 days' notice from the department.
If you run stores on both sides, give each its own tax settings and use the Kansas notice wherever you surcharge in Kansas. We work with businesses in both Kansas Cities remotely, on interchange-plus pricing with a dedicated rep, and our surcharging program includes the Kansas disclosure. The statute and its history are on our Kansas page. A free statement review shows what you pay now.

Common questions
Is this the Kansas City, Missouri page?
No. This page covers Kansas City, Kansas, in Wyandotte County, where Kansas law applies. Kansas City, Missouri is a separate and larger city across the state line, with Missouri's sales tax and no state surcharge statute. Our Kansas City, Missouri page covers that side.
What notice does Kansas require before I surcharge in Kansas City, Kansas?
A clear and conspicuous notice of the surcharge amount at the point of entry or the point of sale, given before the transaction, under K.S.A. 16a-2-403. Visa also requires 30 days' written notice to your acquirer and caps the surcharge at 3% or your cost, and Mastercard caps it at 4% or your cost. Debit and prepaid cards can't be surcharged. Our guide to surcharge signs covers the wording.
How do I find the sales tax rate for a Kansas City, Kansas address?
Look up the exact address with the Kansas Department of Revenue, since your total is the 6.5% state rate plus whatever local taxes apply there. Local rates in Kansas change only on January 1, April 1, July 1 or October 1, and the department announces each change at least 60 days ahead, so recheck before each of those dates.
Do grocery stores in Kansas City, Kansas charge state sales tax on food?
No. Kansas cut the state rate on food and food ingredients to 0% on January 1, 2025, down from 2% in 2024. Prepared food is still taxed at the full 6.5% state rate, and local taxes are figured separately. Give groceries and prepared food separate tax categories in your POS.
We have locations in both Kansas Cities. Can they share one setup?
Not for taxes or surcharge notices. The Kansas store charges Kansas sales tax and needs the Kansas notice before it surcharges, while the Missouri store charges Missouri tax and has no state surcharge statute to follow. Card network caps apply to both. We can set up both locations with one dedicated rep, but give each its own tax rates and signs.
