No total is shown because more than one county and city is listed. An address falls inside only one of each, so these shares are alternatives rather than a stack, and adding them all up would give a figure nobody pays.

What can change the tax you pay in Deer Park, IL

  • ZIP codes shared with a neighbour. 2 of Deer Park's 2 ZIP codes are also reached by Deer Park, Palatine, Arlington Heights and Barrington and 13 other places, so an address in one of them can owe a neighbour's rate instead of Deer Park's.
  • Your exact address. Cook County, Lake County, Kane County and Mchenry 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

The seller generally collects the tax from the buyer at the point of sale and passes it to the authorities that levied it. 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.
