Sales tax in Franklin County, Kansas

By Brent Chudoba, editor Updated

There is no single sales tax rate in Franklin County. It runs from 8% to 11.5% depending on the exact address, because cities and special districts inside the county levy their own on top of the 6.5% state rate. The 6.5% state rate applies everywhere in the county; everything above that depends on where you are standing. These rates were read from Kansas's own published schedule and checked on October 1, 2026.

Why the rate here is not the whole story

Kansas charges 6.5 percent statewide on general merchandise and then stacks a county rate, city rates and community improvement or transportation development district rates whose boundaries do not follow county lines, so a single rate for the whole county does not exist. The county itself levies 1.5 percent countywide. The floor of 8 percent is state plus county in unincorporated areas with no city and no district tax. The ceiling of 11.5 percent is at Ottawa Holiday Inn Express 2 CID, a community improvement or transportation development district that covers a single development rather than a town, so it applies only to the street addresses the state lists for it and not to the surrounding city. Kansas finished phasing its state rate on qualifying food down to 0 percent on January 1 2025, so groceries pay only the local part of these rates, but the figures here are the general merchandise rates.

How do I find the exact rate for an address in Franklin County?

Use Kansas's own address lookup. In Franklin County the rate depends on the address, anywhere from 8% to 11.5%.
