Credit card processing and merchant services in Olathe, KS

Olathe's sales tax rate is 9.475%, according to the city's taxes and fees page, unless your business sits in a special taxing district. The city breaks it into three layers: 6.5% for the State of Kansas, 1.475% for Johnson County and 1.5% for the City of Olathe. The city's share is three taxes of its own: 1% general, 0.375% for street maintenance and 0.125% for parks.

On a receipt, a $200 taxable sale carries $18.95 in tax: $13.00 for the state, $2.95 for the county and $3.00 for the city. Inside a special taxing district the total can be different, so confirm the rate for each address with the Kansas Department of Revenue. Any change to those local rates can only take effect at the start of a quarter.

Groceries get their own tax setting. On food and food ingredients, the 6.5% state share drops to 0%, as it has since January 1, 2025; prepared food doesn't get that break. The county and city taxes are a separate question, so check how they treat groceries before you set up POS terminals.

Kansas lets you surcharge credit cards as long as you give notice first. K.S.A. 16a-2-403 has required, since January 1, 2025, a clear and conspicuous disclosure of the surcharge amount at the point of entry or the point of sale, made before the transaction. The state sets no cap, so the networks' 3% for Visa and 4% for Mastercard apply, and debit cards are off limits. Our Kansas page has the statute, and the Overland Park page covers that city's street tax and districts.

The Census Bureau estimated Olathe's population at 150,025 on July 1, 2025, up 6.2% from its April 2020 base.
