Luxury tax

A luxury tax is a tax on luxury goods: products not considered essential. A luxury tax may be modeled after a sales tax or VAT, charged as a percentage on all items of particular classes, except that it mainly affects the wealthy because the wealthy are the most likely to buy luxuries such as expensive cars, jewelry, etc. It may also be applied only to purchases over a certain amount; for instance, some U.S. states charge luxury tax on real estate transactions over a limit.

A luxury good may be a Veblen good, which is a type of good for which demand increases as price increases. Therefore, the effect of a luxury tax may be to increase demand for certain luxury goods. In general, however, since a luxury good has a high income elasticity of demand by definition, both the income effect and substitution effect will decrease demand sharply as the tax rises.

Luxury tax is based on the concept of positional goods, which are scarce goods whose value arises as status symbols largely from their ranking against other positional goods. This creates a zero-sum game in which the absolute amount of goods purchased is less relevant than the absolute amount of money spent on them and their relative positions. Agents competing in such a game for pure positional goods do not lose utility if some of this money is taken as tax, because their utility comes as status from the amount of money (displayed to be) spent rather than the use-value of the goods themselves. For a pure positional good, a luxury tax is the perfect form of taxation because it raises revenue without any adverse utility effects.

When a luxury tax is imposed, the majority of people are not affected by it and are not subject to the tax. However, over time, what is viewed as "luxury" might change, resulting in more and more people being affected by the tax. Despite the animosity that ensues, the government may view the income from the luxury tax as essential and will not restrict or rescind it. So it may happen over time that goods considered "ordinary" might also incur luxury tax. An example of this can be seen with various commodities in the country of Norway, where at the beginning of last century, oil-powered cars and chocolates were viewed as luxury goods. Thus, additional taxes were levied upon these goods. Today few Norwegians consider cars or chocolate a luxury, but the luxury taxes on these goods remain. In Ireland, many personal hygiene products are within the luxury tax bracket.
