A tax is a compulsory financial charge or some other type of levy imposed on a taxpayer by a governmental organization in order to collectively fund government spending, public expenditures, or as a way to regulate and reduce negative externalities. 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 relief. The first known taxation took place in Ancient Egypt around 3000–2800 BC. Taxes consist of direct or indirect taxes and may be paid in money or as its labor equivalent.
An income tax is a tax imposed on individuals or entities (taxpayers) in respect of the income or profits earned by them. Income tax generally is computed as the product of a tax rate times the taxable income. Taxation rates may vary by type or characteristics of the taxpayer and the type of income.
Public choice, or public choice theory, is "the use of economic tools to deal with traditional problems of political science." Its content includes the study of political behavior. In political science, it is the subset of positive political theory that studies self-interested agents and their interactions, which can be represented in a number of ways—using standard constrained utility maximization, game theory, or decision theory. It is the origin and intellectual foundation of contemporary work in political economy.
In economics and political science, fiscal policy is the use of government revenue collection and expenditure to influence a country's economy. The use of government revenue expenditures to influence macroeconomic variables developed in reaction to the Great Depression of the 1930s, when the previous laissez-faire approach to economic management became unworkable. Fiscal policy is based on the theories of the British economist John Maynard Keynes, whose Keynesian economics theorised that government changes in the levels of taxation and government spending influence aggregate demand and the level of economic activity. Fiscal and monetary policy are the key strategies used by a country's government and central bank to advance its economic objectives. The combination of these policies enables these authorities to target inflation and to increase employment. In modern economies, inflation is conventionally considered "healthy" in the range of 2%–3%. Additionally, it is designed to try to keep GDP growth at 2%–3% percent and the unemployment rate near the natural unemployment rate of 4%–5%. This implies that fiscal policy is used to stabilise the economy over the course of the business cycle.
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.
Tax reform is the process of changing the way taxes are collected or managed by the government and is usually undertaken to improve tax administration or to provide economic or social benefits. Tax reform can include reducing the level of taxation of all people by the government, making the tax system more progressive or less progressive, or simplifying the tax system and making the system more understandable or more accountable.
Tax noncompliance is a range of activities that are unfavorable to a government's tax system. This may include tax avoidance, which is tax reduction by legal means, and tax evasion which is the illegal non-payment of tax liabilities. The use of the term "noncompliance" is used differently by different authors. Its most general use describes non-compliant behaviors with respect to different institutional rules resulting in what Edgar L. Feige calls unobserved economies. Non-compliance with fiscal rules of taxation gives rise to unreported income and a tax gap that Feige estimates to be in the neighborhood of $500 billion annually for the United States.
Although the actual definitions vary between jurisdictions, in general, a direct tax or income tax is a tax imposed upon a person or property as distinct from a tax imposed upon a transaction, which is described as an indirect tax. There is a distinction between direct and indirect tax depending on whether the tax payer is the actual taxpayer or if the amount of tax is supported by a third party, usually a client. The term may be used in economic and political analyses, but does not itself have any legal implications. However, in the United States, the term has special constitutional significance because of a provision in the U.S. Constitution that any direct taxes imposed by the national government be apportioned among the states on the basis of population. In the European Union direct taxation remains the sole responsibility of member states.
A church tax is a tax collected by the state from members of some religious denominations to provide financial support of churches, such as the salaries of its clergy and to pay the operating cost of the church. Not all countries have such a tax. In some countries that do, people who are not members of a religious community are exempt from the tax; in others it is always levied, with the payer often entitled to choose who receives it, typically the state or an activity of social interest.
A flow-through entity (FTE) is a legal entity where income "flows through" to investors or owners; that is, the income of the entity is treated as the income of the investors or owners. Flow-through entities are also known as pass-through entities or fiscally-transparent entities.
Tax amnesty allows taxpayers to voluntarily disclose and pay tax owing in exchange for avoiding tax evasion penalties. It is a limited-time opportunity for a specified group of taxpayers to pay a defined amount, in exchange for forgiveness of a tax liability relating to previous tax periods. It typically expires when some authority begins a tax investigation of the past-due tax.
Conscientious objection to military taxation (COMT) is a legal theory that attempts to extend into the realm of taxation the concessions to conscientious objectors that many governments allow in the case of conscription, thereby allowing conscientious objectors to insist that their tax payments not be spent for military purposes.
A government budget is a projection of the government's revenues and expenditure for a particular period of time often referred to as a financial or fiscal year, which may or may not correspond with the calendar year. Government revenues mostly include taxes while expenditures consist of government spending. A government budget is prepared by the government or other political entity. In most parliamentary systems, the budget is presented to the legislature and often requires approval of the legislature. Through this budget, the government implements economic policy and realizes its program priorities. Once the budget is approved, the use of funds from individual chapters is in the hands of government ministries and other institutions. Revenues of the state budget consist mainly of taxes, customs duties, fees and other revenues. State budget expenditures cover the activities of the state, which are either given by law or the constitution. The budget in itself does not appropriate funds for government programs, hence need for additional legislative measures. The word budget comes from the Old French bougette.
Tax policy refers to the guidelines and principles established by a government for the imposition and collection of taxes. It encompasses both microeconomic and macroeconomic aspects, with the former focusing on issues of fairness and efficiency in tax collection, and the latter focusing on the overall quantity of taxes to be collected and its impact on economic activity. The tax framework of a country is considered a crucial instrument for influencing the country's economy.
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.
Voluntary taxation is a theory that states that taxation should be a voluntary act. Under the theory, people should have the option to pay taxes instead of being forced to pay taxes by their government. Under this theory, the people would control how much they pay and where they spend it. The theory is a part of Objectivist politics and many libertarian ideologies. Proponents of some studies assert that individuals will give to government, paying voluntary taxes to support specific functions.
The hypothecation of a tax is the dedication of the revenue from a specific tax for a particular expenditure purpose. This approach differs from the classical method according to which all government spending is done from a consolidated fund.
Taxes in Germany are levied at various government levels: the federal government, the 16 states (Länder), and numerous municipalities (Städte/Gemeinden). The structured tax system has evolved significantly, since the reunification of Germany in 1990 and the integration within the European Union, which has influenced tax policies. Today, income tax and Value-Added Tax (VAT) are the primary sources of tax revenue. These taxes reflect Germany's commitment to a balanced approach between direct and indirect taxation, essential for funding extensive social welfare programs and public infrastructure. The modern German tax system accentuate on fairness and efficiency, adapting to global economic trends and domestic fiscal needs.
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.
