Ideally, a sales tax is fair, has a high compliance rate, is difficult to avoid, is charged exactly once on any one item, and is simple to calculate and simple to collect. A conventional or retail sales tax attempts to achieve this by charging the tax only on the final end user, unlike a gross receipts tax levied on the intermediate business who purchases materials for production or ordinary operating expenses prior to delivering a service or product to the marketplace.
Most countries in the world have sales taxes or value-added taxes at all or several of the national, state, county or city government levels. Countries in western Europe, especially in Scandinavia have some of the world's highest valued-added taxes. Norway, Denmark and Sweden have the highest VATs at 25%, although reduced rates are used in some cases, as for groceries and newspaper.
