Ad valorem tax

An ad valorem tax imposes a tax on a good or asset, depending on its value. The tax is usually expressed as a percentage. For example, in the UK, VAT is charged at 20% on most goods offered for sale.

Ad valorem means – according to value. Thus it is a tax which is flexible and depends on the value of the asset or the price of the good. In this regard, it is likely to be more progressive than a specific tax. If your house is worth more, you will pay a higher amount of stamp duty. Therefore, the wealthy tend to pay more stamp duty than those on a low income.

3. Consumption tax – VAT (20%)

Most modern economies charge VAT –  a form of a consumption tax on the purchase price of the final good. It is an indirect tax because the retailer is responsible for paying the tax, though the consumer will pay higher prices.

VAT is different from a sales tax in that VAT is only due on the value added by the retailer. e.g. if the cost is £10, and the selling price is £25, the retailer is only responsible for paying VAT on the extra £15. The manufacturer is also due to pay VAT on the value added by their stage of production.
