Definition

Noun: A tax calculated as a percentage of the assessed value of the item being taxed, such as property or imported goods. It is levied on the value of a transaction or of property.

Usage

An ad valorem tax is imposed based on the value of an asset or transaction. The most common examples are property taxes (based on real estate value) and sales taxes (based on the sale price of goods). The term is often contrasted with a "specific tax," which is a fixed amount per unit.

Examples

• The county imposes an ad valorem tax on all residential property.
• Imported luxury cars are subject to a high ad valorem tax.
• The proposed bill would replace the flat fee with an ad valorem tax based on the vehicle's market value.

Advanced Usage

• In economic policy: The principle of an ad valorem tax is central to value-added tax (VAT) systems, where tax is applied at each stage of production based on the value added.
• In legal contexts: Disputes may arise over the proper valuation method used to calculate an ad valorem tax.
