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 no sales tax. The floor of 6.5 percent is state plus county in unincorporated areas with no city and no district tax. The ceiling of 8.5 percent is at Ulysses. 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.
