Sales taxes in the United States - Wikipedia, the free encyclopedia Sales taxes in the United States are taxes added onto the price of goods or services that are purchased in the United States. A sales tax is a tax on consumption, which is displayed as a percentage of the sale price. Sales taxes are assessed by every state except Alaska, Delaware, Montana, New Hampshire and Oregon.[citation needed] Hawaii has a similar tax although it is charged to businesses instead of consumers.[citation needed] In some cases, sales taxes are also assessed at the county or municipal level. in Traveling > Valutor och tidszonerwith momssalesskattstatestaxunitedusavat
