As in other countries in the world, the federal and state governments of the United States of America collects taxes, such as income tax, in order to pay for publicly funded programs, such as the military, public works and welfare. In addition, taxes are also levied on some sales and services, levies that visitors are not exempt from. State sales and use taxes, in other countries known as goods and services taxes, are set individually by each state, meaning that rates vary from no tax at all (in states like Alaska, Delaware, Hawaii, Montana, New Hampshire, New Mexico and Oregon) to upwards of 7%. In many states, local county and municipal governments levy additional sales taxes that can range up to 5% of purchases.

As well as sales taxes, visitors can expect levies on vehicle and other short-term rentals (1.5 to 10%), lodging (4 to 14.5%) and prepared food and beverages (7 to 10%). While not all states levy these taxes, visitors should be prepared for the possibility of an increase at the cash register.

Taxes are not typically included in prices quoted. Therefore, when viewing a rate at a hotel, car rental agency or restaurant, expect tax to be added to the final tab. When asking for rates, ask if the price includes tax.

When flying, expect to be charged airport improvement, flight segment, domestic transportation and federal security taxes. For international travelers, expect to pay arrival and departure taxes. In some cases, these taxes are not paid when you purchase your ticket and must be paid at the airport or other point of entry.
