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, and tax compliance refers to policy actions and individual behaviour aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs. The first known taxation took place in Ancient Egypt around 3000–2800 BC. A failure to pay in a timely manner (non-compliance), 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 labor equivalent.
Transport economics is a branch of economics founded in 1959 by American economist John R. Meyer that deals with the allocation of resources within the transport sector. It has strong links to civil engineering. Transport economics differs from some other branches of economics in that the assumption of a spaceless, instantaneous economy does not hold. People and goods flow over networks at certain speeds. Demands peak. Advance ticket purchase is often induced by lower fares. The networks themselves may or may not be competitive. A single trip may require the bundling of services provided by several firms, agencies and modes.
In economics, an externality or external cost is an indirect cost or benefit to an uninvolved third party that arises as an effect of another party's activity. Externalities can be considered as unpriced goods involved in either consumer or producer market transactions. Air pollution from motor vehicles is one example. The cost of air pollution to society is not paid by either the producers or users of motorized transport to the rest of society. Water pollution from mills and factories is another example. All consumers are all made worse off by pollution but are not compensated by the market for this damage. A positive externality is when an individual's consumption in a market increases the well-being of others, but the individual does not charge the third party for the benefit. The third party is essentially getting a free product. An example of this might be the apartment above a bakery receiving the benefit of enjoyment from smelling fresh pastries every morning. The people who live in the apartment do not compensate the bakery for this benefit.
The welfare state of the United Kingdom began to evolve in the 1900s and early 1910s, and comprises expenditures by the government of the United Kingdom of Great Britain and Northern Ireland intended to improve health, education, employment and social security. The British system has been classified as a liberal welfare state system.
Welfare, or commonly social welfare, is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance programs which provide support only to those who have previously contributed, as opposed to social assistance programs which provide support on the basis of need alone. The International Labour Organization defines social security as covering support for those in old age, support for the maintenance of children, medical treatment, parental and sick leave, unemployment and disability benefits, and support for sufferers of occupational injury.
Public finance is the study of the role of the government in the economy. It is the branch of economics that assesses the government revenue and government expenditure of the public authorities and the adjustment of one or the other to achieve desirable effects and avoid undesirable ones. The purview of public finance is considered to be threefold, consisting of governmental effects on:
- The efficient allocation of available resources;
- The distribution of income among citizens; and
- The stability of the economy.
A Pigouvian tax is a tax on any market activity that generates negative externalities. The tax is normally set by the government to correct an undesirable or inefficient market outcome, and does so by being set equal to the external marginal cost of the negative externalities. In the presence of negative externalities, social cost includes private cost and external cost caused by negative externalities. This means the social cost of a market activity is not covered by the private cost of the activity. In such a case, the market outcome is not efficient and may lead to over-consumption of the product. Often-cited examples of negative externalities are environmental pollution and increased public healthcare costs associated with tobacco and sugary drink consumption.
Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives. It is used to determine options which provide the best approach to achieving benefits while preserving savings in, for example, transactions, activities, and functional business requirements. A CBA may be used to compare completed or potential courses of action, and to estimate or evaluate the value against the cost of a decision, project, or policy. It is commonly used to evaluate business or policy decisions, commercial transactions, and project investments. For example, the U.S. Securities and Exchange Commission must conduct cost-benefit analyses before instituting regulations or deregulations.
Public expenditure is spending made by the government of a country on collective needs and wants, such as pension, provisions, security, infrastructure, etc. Until the 19th century, public expenditure was limited as laissez faire philosophies believed that money left in private hands could bring better returns. In the 20th century, John Maynard Keynes argued the role of public expenditure in determining levels of income and distribution in the economy. Since then, government expenditures has shown an increasing trend. Sources of government revenue include taxes, and non-tax revenues.
Taxation in Indonesia includes income tax, value added tax and carbon tax.
Tax policy includes the guidelines developed by a government regarding how taxes are imposed, in what amounts, and on whom. It has both microeconomic and macroeconomic aspects. The macroeconomic aspect concerns the overall quantity of taxes to collect, which can inversely affect the level of economic activity; this is one component of fiscal policy. The microeconomic aspects concern issues of fairness and allocative efficiency. A country’s tax framework is a key policy instrument that is intended to positively influence the country's economy.
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.
Proposition 218 is an adopted initiative constitutional amendment which revolutionized local and regional government finance and taxation in California. Named the "Right to Vote on Taxes Act," it was sponsored by the Howard Jarvis Taxpayers Association as a constitutional follow-up to the landmark property tax reduction initiative constitutional amendment, Proposition 13, approved in 1978. Proposition 218 was approved and adopted by California voters during the November 5, 1996, statewide general election.
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.
In the United States, a special assessment is a charge that public authorities can assess against real estate parcels for certain public projects. This charge is levied in a specific geographic area known as a special assessment district (SAD). A special assessment may only be levied against parcels of real estate which have been identified as having received a direct and unique "benefit" from the public project.
Rational economic exchange also called goods exchange economy is an economic transaction where goods or services are transferred from the provider for a return of relative value (compensation) from the receiver in a manner that advances the economic interests of both parties. Rational economic exchange is implied in voluntary economic transactions between private parties where it is assumed that an economic transaction would not occur unless both parties believed they would be better off after the trade. Rational economic exchange can be implied in governmental taxation and spending where the agents of the citizen—government legislators and administrators—implement fiscal policy where tax assessment to the citizen is related, substantially, to an implied level of government service.
Taxation in Denmark consists of a comprehensive system of direct and indirect taxes. Ever since the income tax was introduced in Denmark via a fundamental tax reform in 1903, it has been a fundamental pillar in the Danish tax system. Today various personal and corporate income taxes yield around two thirds of the total Danish tax revenues, indirect taxes being responsible for the last third. The state personal income tax is a progressive tax while the municipal income tax is a proportional tax above a certain income level.
Several theories of taxation exist in public economics. Governments at all levels need to raise revenue from a variety of sources to finance public-sector expenditures.
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.
Taxation in Brazil is complex, with over sixty forms of tax. Historically, tax rates were low and tax evasion and avoidance were widespread. The 1988 Constitution called for an enhanced role of the State in society, requiring increased tax revenue. In 1960, and again between 1998 and 2004, efforts were made to make the collection system more efficient. Tax revenue gradually increased from 13.8% of GDP in 1947 to 37.4% in 2005. Tax revenue has become quite high by international standards, but without realising commensurate social benefit. More than half the total tax is in the regressive form of taxes on consumption.
