I'm assuming you're referring to sales tax, right?
broken down by state, county, and city, and then you add all of these together
depending on where you're at. Most people don't remember the individual
rates, they're just aware of the combined sales tax. For instance, I think
Phoenix's sales tax rate right now is 7.8%.
It's anywhere from
7% to 10%, but most are right around 7.8% or 8.1%.
