An income tax is a tax levied on the income of individuals or businesses (corporations or other legal entities). Various income tax systems exist, with varying degrees of tax incidence. Income taxation can be progressive, proportional, or regressive. When the tax is levied on the income of companies, it is often called a corporate tax, corporate income tax, or profit tax. Individual income taxes often tax the total income of the individual (with some deductions permitted), while corporate income taxes often tax net income (the difference between gross receipts, expenses, and additional write-offs). Various systems define income differently, and often allow notional reductions of income (such as a reduction based on number of children supported).

Principles

The "tax net" refers to the types of payment that are taxed, which included personal earnings (wages), capital gains, and business income. The rates for different types of income may vary and some may not be taxed at all. Capital gains may be taxed when realized (e.g. when shares are sold) or when incurred (e.g. when shares appreciate in value). Business income may only be taxed if it is significant or based on the manner in which it is paid. Some types of income, such as interest on bank savings, may be considered as personal earnings (similar to wages) or as a realized property gain (similar to selling shares). In some tax systems, personal earnings may be strictly defined where labor, skill, or investment is required (e.g. wages); in others, they may be defined broadly to include windfalls (e.g. gambling wins).

Tax rates may be progressive, regressive, or proportional. A progressive tax applies progressively higher tax rates as earnings reach higher levels. For example, the first $10,000 in earnings may be taxed at 5%, the next $10,000 at 10%, and any more income at 20%. Alternatively, a flat tax taxes all earnings at the same rate. A regressive income tax may apply to income up to a certain amount, such as taxing only the first $90,000 earned. A tax system may use different taxation methods for different types of income. However, the idea of a progressive income tax has garnered support from economists and political scientists of many different ideologies, from Adam Smith in The Wealth of Nations^[1] to Karl Marx in The Communist Manifesto.^[2]

Personal income tax is often collected on a pay-as-you-earn basis, with small corrections made soon after the end of the tax year. These corrections take one of two forms: payments to the government by taxpayers who did not pay enough during the tax year; and tax refunds from the government to those who overpaid. Income tax systems often have deductions available that lessen the total tax liability by reducing total taxable income. They may allow losses from one type of income to be counted against another. For example, a loss on the stock market may be deducted against taxes paid on wages. Other tax systems may isolate the loss, such that business losses can only be deducted against business tax by carrying forward the loss to later tax years.

History

The concept of taxing income is a modern innovation and presupposes several things: a money economy, reasonably accurate accounts, a common understanding of receipts, expenses and profits, and an orderly society with reliable records. For most of the history of civilization, these preconditions did not exist, and taxes were based on other factors. Taxes on wealth, social position, and ownership of the means of production (typically land and slaves) were all common. Practices such as tithing, or an offering of firstfruits, existed from ancient times, and can be regarded as a precursor of the income tax, but they lacked precision and certainly were not based on a concept of net increase.

Han Dynasty (ancient China)

In the year 10, Emperor Wang Mang of the Xin Dynasty instituted an unprecedented tax -- the income tax -- at the rate of 10 percent of profits, for professionals and skilled labor. (Previously, all taxes were either head tax or property tax.) He was overthrown 13 years later in 23 CE and earlier laissez-faire policies were restored during the Later Han.

Kingdom of Great Britain

Another income tax was implemented in Britain by William Pitt the Younger in his budget of December 1798 to pay for weapons and equipment in preparation for the Napoleonic wars. Pitt's new graduated income tax began at a levy of 2d in the pound (0.8333%) on incomes over £60 and increased up to a maximum of 2s in the pound (10%) on incomes of over £200 (£170,542 in 2007). Pitt hoped that the new income tax would raise £10 million (£8,527,100,000 in 2007) but actual receipts for 1799 totalled just over £6 million (see UK income tax history for more information).^[3]

United States

The first United States income tax was imposed in July 1861, at 3% of all incomes over 800 dollars in order to help pay for the war effort in the American Civil War.

In 1868, Congress again focused its taxation efforts on tobacco and distilled spirits and eliminated the income tax in 1872. It had a short-lived revival in 1894 and 1895. In the latter year, the U.S. Supreme Court decided that the income tax was unconstitutional because it was not apportioned among the states in conformity with the Constitution.

In 1913, the 16th Amendment to the Constitution made the income tax a permanent fixture in the U.S. tax system. The amendment gave Congress legal authority to tax income and resulted in a revenue law that taxed incomes of both individuals and corporations. In fiscal year 1918, annual internal revenue collections for the first time passed the billion-dollar mark, rising to $5.4 billion by 1920. With the advent of World War II, employment increased, as did tax collections—to $7.3 billion. The withholding tax on wages was introduced in 1943 and was instrumental in increasing the number of taxpayers to 60 million and tax collections to $43 billion by 1945. ^[4][5] This tax was repealed and replaced by another income tax in 1962. ^[6]

Types

Personal

A personal or individual income tax is levied on the total income of the individual (with some deductions permitted). It is often collected on a pay-as-you-earn basis, with small corrections made soon after the end of the tax year. These corrections take one of two forms: payments to the government, for taxpayers who have not paid enough during the tax year; and tax refunds from the government for those who have overpaid. Income tax systems will often have deductions available that lessen the total tax liability by reducing total taxable income. They may allow losses from one type of income to be counted against another. For example, a loss on the stock market may be deducted against taxes paid on wages.

Corporate

Corporate tax refers to a direct tax levied on the profits made by companies or associations and often includes capital gains of a company. Earnings are generally considered gross revenue minus expenses. Corporate expenses related to capital expenditures are usually deducted in full (for example, trucks are fully deductible in the Canadian tax system, while a corporate sports car is only partly deductible) over their useful lives by using percentage rates based on the class of asset they belong to.

Accounting principles and tax rules about recognition of expenses and revenue will vary at times, giving rise to book-tax differences. If the book-tax difference is carried over more than a year, it is referred to as a deferred tax. Future assets and liabilities created by a deferred tax are reported on the balance sheet.

Payroll

A payroll tax generally refers to two kinds of taxes: employee and employer payroll taxes. Employee payroll taxes are taxes which employers are required to withhold from employees' pay, also known as withholding, pay-as-you-earn (PAYE) or pay-as-you-go (PAYG) tax. These withholdings contribute to the payment of an employee's personal income tax obligation; if the payments exceed this obligation, the employee may be eligible for a tax refund or carryforward to future periods.

Employer payroll taxes are paid from the employer's own funds, either as a fixed charge per employee or as a percentage of each employee's pay. Payroll taxes often cover government social insurance programs, such as social security, health care, unemployment, and disability. These payments do not count toward the income taxes of employees and employers, but are normally deductible by the employer as a business expense.

Inheritance

The inheritance tax, estate tax and death duty are the names given to various taxes which arise on the death of an individual. In international tax law, there is a distinction between an estate tax and an inheritance tax: the former taxes the personal representatives of the deceased, while the latter taxes the beneficiaries of the estate. However, this distinction is not universally recognized. For example, the "inheritance tax" in the UK is a tax on personal representatives, and is therefore, strictly speaking, an estate tax.

Capital gains tax

A capital gains tax is the tax levied on profits from the sale of capital assets. In many cases, the amount of a capital gain is treated as income and subject to the marginal rate of income tax.

In an inflationary environment, capital gains may be, to some extent, illusory. If prices in general have doubled over five years, then selling an asset for twice the price it was purchased at five years earlier represents no gain at all. Partly to compensate for such changes in the value of money over time, some jurisdictions, such as the United States, give a favorable capital gains tax rate based on the length of holding. European jurisdictions have a similar rate reduction to nil on certain property transactions that qualify for the participation exemption. In Canada, 20–50% of the gain is taxable income. In India, Short Term Capital Gains Tax (arising before one year) is 10% [15 % from F.Y 2008-09 as per Finance Act 2008] flat rate of the gains and Long Term Capital Gains Tax is nil for stocks and mutual fund units held one year or more, provided the sale of shares involved payment of the Securities Transaction Tax, and 20% for any other assets held three years or more.

Around the world

Income taxes are used in most countries around the world. The tax systems vary greatly and can be progressive, proportional, or regressive, depending on the type of tax. Comparison of tax rates around the world is a difficult and somewhat subjective enterprise. Tax laws in most countries are extremely complex, and tax burden falls differently on different groups in each country and sub-national unit. Of course, services provided by governments in return for taxation also vary, making comparisons all the more difficult.

Criticism

Critics have stated that income tax systems can penalize work, discourage saving and investment, hinder the competitiveness of business and economic growth.^[7][8] Income taxes are not border-adjustable; meaning the tax component embedded into products via taxes imposed on companies cannot be removed when exported to a foreign country (see Effect of taxes and subsidies on price). Taxation systems such as a national sales tax or value added tax remove the tax component when goods are exported and apply the tax component on imports.^[9] The principles of an income tax are also argued by critics. Frank Chodorov wrote "... you come up with the fact that it gives the government a prior lien on all the property produced by its subjects." The government "unashamedly proclaims the doctrine of collectivized wealth. ... That which it does not take is a concession."^[5]

Transparency / Public Disclosure

Public disclosure of personal income tax filings occurs in Finland and Norway — and it was once practiced in the United States as well.^[10]
