For anyone coming from a country where tax is already built into the displayed price, American sales tax tends to be a surprise: the amount charged at checkout is always higher than the price tag, and the difference depends on where you're shopping.
A tax that changes from place to place
Sales tax is set at the state level, and in many places also at the county or city level, which creates different rates even within the same state. Some states, like Oregon and Delaware, don't charge a general sales tax on most goods.
In addition, certain categories, like basic groceries or medications, may be taxed differently or partially exempt, depending on local law.
Why it doesn't appear on the tag
Unlike in many countries, the common practice in the U.S. is to display prices without tax and calculate sales tax only at checkout. That's part of the local retail culture, but it takes some adjustment for anyone used to seeing the final price upfront.
This same habit shows up on restaurant and service receipts too, so it's worth building in extra room when planning a shopping budget.
Planning purchases with more predictability
One practical way to avoid surprises is to look up your city's approximate tax rate and mentally add it to the price before deciding on a purchase, especially for bigger-ticket items.
Since rates and exemptions change often and vary by jurisdiction, more specific questions should be confirmed with official state sources or a tax professional.
