How sales tax works

Sales tax is a consumption tax charged at the point of sale. In the US, rates combine state, county, and city taxes - the state base rate shown here is the starting point, and many areas add 1-3% on top. In Canada, the rate is a combined GST/HST (or GST + provincial sales tax) set by each province.
