A tax is a compulsory financial charge or some other type of levy imposed on a taxpayer by a governmental organization in order to fund government spending and various public expenditures. A failure to pay, along with evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labour equivalent. The first known taxation took place in Ancient Egypt around 3000–2800 BC.
In the social sciences, the free-rider problem is a type of market failure that occurs when those who benefit from resources, public goods, or services of a communal nature do not pay for them or under-pay. Free riders are a problem because while not paying for the good, they may continue to access or use it. Thus, the good may be under-produced, overused or degraded. Additionally, it has been shown that despite evidence that people tend to be cooperative by nature, the presence of free-riders cause this prosocial behaviour to deteriorate, perpetuating the free-rider problem.
In economics, an externality is a cost or benefit that is imposed on a third party who did not agree to incur that cost or benefit. For the purpose of these statements, overall cost and benefit to society is defined as the sum of the imputed monetary value of benefits and costs to all parties involved. The concept of externality was first developed by economist Arthur Pigou in the 1920s. Air pollution from motor vehicles is an example of a negative externality. The costs of the air pollution for the rest of society is not compensated for by either the producers or users of motorized transport.
In taxation and accounting, transfer pricing refers to the rules and methods for pricing transactions within and between enterprises under common ownership or control. Because of the potential for cross-border controlled transactions to distort taxable income, tax authorities in many countries can adjust intragroup transfer prices that differ from what would have been charged by unrelated enterprises dealing at arm’s length. The OECD and World Bank recommend intragroup pricing rules based on the arm’s-length principle, and 19 of the 20 members of the G20 have adopted similar measures through bilateral treaties and domestic legislation, regulations, or administrative practice. Countries with transfer pricing legislation generally follow the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations in most respects, although their rules can differ on some important details.
Many countries have entered into tax treaties with other countries to avoid or mitigate double taxation. Such treaties may cover a range of taxes including income taxes, inheritance taxes, value added taxes, or other taxes. Besides bilateral treaties, multilateral treaties are also in place. For example, European Union (EU) countries are parties to a multilateral agreement with respect to value added taxes under auspices of the EU, while a joint treaty on mutual administrative assistance of the Council of Europe and the Organisation for Economic Co-operation and Development (OECD) is open to all countries. Tax treaties tend to reduce taxes of one treaty country for residents of the other treaty country to reduce double taxation of the same income.
An ad valorem tax is a tax whose amount is based on the value of a transaction or of property. It is typically imposed at the time of a transaction, as in the case of a sales tax or value-added tax (VAT). An ad valorem tax may also be imposed annually, as in the case of a real or personal property tax, or in connection with another significant event. In some countries a stamp duty is imposed as an ad valorem tax.
Double taxation is the levying of tax by two or more jurisdictions on the same income, asset, or financial transaction.
An indirect tax is a tax that is levied upon goods and services before they reach the customer who ultimately pays the indirect tax as a part of market price of the good or service purchased. Alternatively, if the entity who pays taxes to the tax collecting authority does not suffer a corresponding reduction in income, i.e., impact and tax incidence are not on the same entity meaning that tax can be shifted or passed on, then the tax is indirect.
Tax revenue is the income that is gained by governments through taxation. Taxation is the primary source of government revenue. Revenue may be extracted from sources such as individuals, public enterprises, trade, royalties on natural resources and/or foreign aid. An inefficient collection of taxes is greater in countries characterized by poverty, a large agricultural sector and large amounts of foreign aid.
In neoclassical economics, a market distortion is any event in which a market reaches a market clearing price for an item that is substantially different from the price that a market would achieve while operating under conditions of perfect competition and state enforcement of legal contracts and the ownership of private property. A distortion is "any departure from the ideal of perfect competition that therefore interferes with economic agents maximizing social welfare when they maximize their own". A proportional wage-income tax, for instance, is distortionary, whereas a lump-sum tax is not. In a competitive equilibrium, a proportional wage income tax discourages work.
Optimal tax theory or the theory of optimal taxation is the study of designing and implementing a tax that maximises a social welfare function subject to economic constraints. The social welfare function used is typically a function of individuals' utilities, most commonly some form of utilitarian function, so the tax system is chosen to maximise the aggregate of individual utilities. Tax revenue is required to fund the provision of public goods and other government services, as well as for redistribution from rich to poor individuals. However, most taxes distort individual behavior, because the activity that is taxed becomes relatively less desirable; for instance, taxes on labour income reduce the incentive to work. The optimization problem involves minimizing the distortions caused by taxation, while achieving desired levels of redistribution and revenue. Some taxes are thought to be less distorting, such as lump-sum taxes and Pigouvian taxes, where the market consumption of a good is inefficient and a tax brings consumption closer to the efficient level.
The Automated Payment Transaction (APT) tax is a small, uniform tax on all economic transactions — involve simplification, base broadening, reductions in marginal tax rates, the elimination of tax and information returns and the automatic collection of tax revenues at the payment source. This proposal is to replace all United States taxes with a single tax on every transaction in the economy. The APT approach would extend the tax base from income, consumption and wealth to all transactions. Proponents regard it as a revenue neutral transactions tax, whose tax base is primarily made up of financial transactions. It is based on the fundamental view of taxation as a "public brokerage fee accessed by the government to pay for the provision of the monetary, legal and political institutions that protect private property rights and facilitate market trade and commerce." The APT tax extends the tax reform ideas of John Maynard Keynes, James Tobin and Lawrence Summers, to their logical conclusion, namely to tax the broadest possible tax base at the lowest possible tax rate. The goal is to significantly improve economic efficiency, enhance stability in financial markets, and reduce to a minimum the costs of tax administration.
The implied level of government service is the value of government benefits and services provided a person, partnership, corporation, or other legal entity over a given period of time, including the proportional value of general governmental expenses and social welfare costs.
Imputed income is the accession to wealth that can be attributed, or imputed, to a person when they avoid paying for services by providing the services to themselves, or when the person avoids paying rent for durable goods by owning the durable goods, as in the case of imputed rent.
Fiscal localism comprises institutions of localized monetary exchange. Sometimes considered a backlash against global capitalism or economic globalization, fiscal localism affords voluntary, market structures that help communities trade more efficiently within their communities and regions.
In public choice theory, tax choice is the belief that individual taxpayers should have direct control over how their taxes are spent. Its proponents apply the theory of consumer choice to public finance. They claim taxpayers react positively when they are allowed to allocate portions of their taxes to specific spending.
Transfer mispricing, also known as transfer pricing manipulation or fraudulent transfer pricing, refers to trade between related parties at prices meant to manipulate markets or to deceive tax authorities. The legality of the process varies between tax jurisdictions; most regard it as a type of fraud or tax evasion.
The benefit principle is a concept in the theory of taxation from public finance. It bases taxes to pay for public-goods expenditures on a politically-revealed willingness to pay for benefits received. The principle is sometimes likened to the function of prices in allocating private goods. In its use for assessing the efficiency of taxes and appraising fiscal policy, the benefit approach was initially developed by Knut Wicksell (1896) and Erik Lindahl (1919), two economists of the Stockholm School. Wicksell's near-unanimity formulation of the principle was premised on a just income distribution. The approach was extended in the work of Paul Samuelson, Richard Musgrave, and others. It has also been applied to such subjects as tax progressivity, corporation taxes, and taxes on property or wealth. The unanimity-rule aspect of Wicksell's approach in linking taxes and expenditures is cited as a point of departure for the study of constitutional economics in the work of James Buchanan.
Goods and Services Tax (GST) is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multistage, destination-based tax: comprehensive because it has subsumed almost all the indirect taxes except a few state taxes. Multi-staged as it is, the GST is imposed at every step in the production process, but is meant to be refunded to all parties in the various stages of production other than the final consumer and as a destination-based tax, it is collected from point of consumption and not point of origin like previous taxes.
A value-added tax (VAT), known in some countries as a goods and services tax (GST), is a type of tax that is assessed incrementally. It is levied on the price of a product or service at each stage of production, distribution, or sale to the end consumer. If the ultimate consumer is a business that collects and pays to the government VAT on its products or services, it can reclaim the tax paid. It is similar to, and is often compared with, a sales tax.
