Sales tax can be tricky, especially when you are analyzing combined sales tax rates (state rate plus city or local rate).
In some states (Delaware, New Hampshire, and Oregon) you will find no sales tax. In others (Alaska, and Montana) you will find no State sales tax but you may be charged local sales tax.
In many states you can cross the street, and be subjected to a completely different set of sales tax rules.
The highest average combined rates (highest to lowest) are in Tennessee, Arkansas, Louisiana, Washington, and Oklahoma. The lowest are (lowest to highest) Alaska, Hawaii, Maine, and Wisconsin.
The highest combined rate is in Tuba City, Arizona (%12.725), though Homer and Seldovia, AK, and Snowmass, CO have a higher local rate (7.5%)
The list goes on, and the people at the Tax Foundation have done a very good job analyzing this data. To see the article and read more visit:
