What can change the tax you pay in Gardner, IL
- ZIP codes shared with a neighbour. 2 of Gardner's 2 ZIP codes are also reached by Braceville, Braidwood, Coal City and Essex and 1 other place, so an address in one of them can owe a neighbour's rate instead of Gardner's.
- Your exact address. Grundy County, Kankakee County and Will County cover only part of this area, so an address inside them is taxed differently from one just outside. A ZIP code is a postal delivery route and was never drawn to follow tax boundaries.
- What you are buying. Categories are not taxed alike. The calculator switches between general merchandise, prepared food and lodging, which are the categories we hold rates for here.

How sales tax is collected

In most states it is added at the till rather than included in the advertised price. Read how sales tax works, including sourcing rules, online purchases and who is required to collect.
