Sales tax in Kansas City, Missouri stacks the Missouri state rate, the Jackson County rate, and the city of Kansas City’s own tax for a combined 8.725% on general goods. Food is treated differently: Missouri taxes qualifying groceries at a reduced state rate, while prepared and restaurant food pays the full rate. This free calculator gets the breakdown right for each item type.
How it works
The calculator stores each component separately and swaps the state portion depending on item type:
state (general) = 4.225%
state (grocery) = 1.225% (Missouri reduced food rate)
county = 1.375% (Jackson County)
city = 3.125% (Kansas City)
For general goods and prepared food, the full state rate applies, summing to about 8.725%. For grocery food, the reduced 1.225% state rate replaces 4.225%, lowering the combined rate while local county and city taxes stay. Tax is the price times the summed rate; total is price plus tax.
Notes and example
A $100 general purchase at 8.725% adds $8.73 for a $108.73 total. The same $100 in groceries uses the reduced state rate, so the combined rate falls to about 5.725% and tax is roughly $5.73. Special districts (CIDs, TDDs) can add more at specific addresses; verify exact rates with the Missouri Department of Revenue. Everything runs locally; nothing is uploaded.
