What type of tax is usually based on a percentage of the total value of purchases made?

Sales tax is a consumption tax that is typically calculated as a percentage of the purchase price of goods and services. It is imposed at the point of sale and is collected by the retailer from the consumer, who then remits the tax to the government. This tax varies by jurisdiction, with different states or localities applying different rates.

Sales tax is distinct from excise tax, which is usually applied to specific goods, such as gasoline or tobacco, and is typically included in the price rather than added at the point of sale. Additionally, income tax is based on the income earned by individuals or corporations, while capital gains tax is levied on the profit made from the sale of assets or investments. These types of taxes are calculated differently and do not directly relate to the value of purchases made by consumers.
