Tax - Purposes and Effects

Purposes and Effects

Money provided by taxation has been used by states and their functional equivalents throughout history to carry out many functions. Some of these include expenditures on war, the enforcement of law and public order, protection of property, economic infrastructure (roads, legal tender, enforcement of contracts, etc.), public works, social engineering, and the operation of government itself. Governments also use taxes to fund welfare and public services. A portion of taxes also go to pay off the state's debt and the interest this debt accumulates. These services can include education systems, health care systems, pensions for the elderly, unemployment benefits, and public transportation. Energy, water and waste management systems are also common public utilities. Colonial and modernizing states have also used cash taxes to draw or force reluctant subsistence producers into cash economies.

Governments use different kinds of taxes and vary the tax rates. This is done to distribute the tax burden among individuals or classes of the population involved in taxable activities, such as business, or to redistribute resources between individuals or classes in the population. Historically, the nobility were supported by taxes on the poor; modern social security systems are intended to support the poor, the disabled, or the retired by taxes on those who are still working. In addition, taxes are applied to fund foreign aid and military ventures, to influence the macroeconomic performance of the economy (the government's strategy for doing this is called its fiscal policy; see also tax exemption), or to modify patterns of consumption or employment within an economy, by making some classes of transaction more or less attractive.

A nation's tax system is often a reflection of its communal values or/and the values of those in power. To create a system of taxation, a nation must make choices regarding the distribution of the tax burden—who will pay taxes and how much they will pay—and how the taxes collected will be spent. In democratic nations where the public elects those in charge of establishing the tax system, these choices reflect the type of community that the public wishes to create. In countries where the public does not have a significant amount of influence over the system of taxation, that system may be more of a reflection on the values of those in power.

All large businesses incur administrative costs in the process of delivering revenue collected from customers to the suppliers of the goods or services being purchased. Taxation is no different, the resource collected from the public through taxation is always greater than the amount which can be used by the government. The difference is called compliance cost, and includes for example the labour cost and other expenses incurred in complying with tax laws and rules. The collection of a tax in order to spend it on a specified purpose, for example collecting a tax on alcohol to pay directly for alcoholism rehabilitation centres, is called hypothecation. This practice is often disliked by finance ministers, since it reduces their freedom of action. Some economic theorists consider the concept to be intellectually dishonest since, in reality, money is fungible. Furthermore, it often happens that taxes or excises initially levied to fund some specific government programs are then later diverted to the government general fund. In some cases, such taxes are collected in fundamentally inefficient ways, for example highway tolls.

Some economists, especially neo-classical economists, argue that all taxation creates market distortion and results in economic inefficiency. They have therefore sought to identify the kind of tax system that would minimize this distortion.

Since governments also resolve commercial disputes, especially in countries with common law, similar arguments are sometimes used to justify a sales tax or value added tax. Others (e.g. libertarians) argue that most or all forms of taxes are immoral due to their involuntary (and therefore eventually coercive/violent) nature. The most extreme anti-tax view is anarcho-capitalism, in which the provision of all social services should be voluntarily bought by the person(s) using them.
