A flat tax is a tax with a single rate on the taxable amount, after accounting for any deductions or exemptions from the tax base. It is not necessarily a fully proportional tax. Implementations are often progressive due to exemptions, or regressive in case of a maximum taxable amount. There are various tax systems that are labeled "flat tax" even though they are significantly different. The defining characteristic is the existence of only one tax rate other than zero, as opposed to multiple non-zero rates that vary depending on the amount subject to taxation.
A pay-as-you-earn tax (PAYE), or pay-as-you-go (PAYG) in Australia, is a withholding of taxes on income payments to employees. Amounts withheld are treated as advance payments of income tax due. They are refundable to the extent they exceed tax as determined on tax returns. PAYE may include withholding the employee portion of insurance contributions or similar social benefit taxes. In most countries, they are determined by employers but subject to government review. PAYE is deducted from each paycheck by the employer and must be remitted promptly to the government. Most countries refer to income tax withholding by other terms, including pay-as-you-go tax.
Payroll taxes are taxes imposed on employers or employees, and are usually calculated as a percentage of the salaries that employers pay their employees. By law, some payroll taxes are the responsibility of the employee and others fall on the employer, but almost all economists agree that the true economic incidence of a payroll tax is unaffected by this distinction, and falls largely or entirely on workers in the form of lower wages. Because payroll taxes fall exclusively on wages and not on returns to financial or physical investments, payroll taxes may contribute to underinvestment in human capital, such as higher education.
Income tax in the Netherlands is regulated by the Wet inkomstenbelasting 2001.
In the United States income tax system, adjusted gross income (AGI) is an individual's total gross income minus specific deductions. It is used to calculate taxable income, which is AGI minus allowances for personal exemptions and itemized deductions. For most individual tax purposes, AGI is more relevant than gross income.
Taxation in Ireland in 2017 came from Personal Income taxes, and Consumption taxes, being VAT and Excise and Customs duties. Corporation taxes represents most of the balance, but Ireland's Corporate Tax System (CT) is a central part of Ireland's economic model. Ireland summarises its taxation policy using the OECD's Hierarchy of Taxes pyramid, which emphasises high corporate tax rates as the most harmful types of taxes where economic growth is the objective. The balance of Ireland's taxes are Property taxes and Capital taxes.
Tax withholding, also known as tax retention, pay-as-you-earn tax or tax deduction at source, is income tax paid to the government by the payer of the income rather than by the recipient of the income. The tax is thus withheld or deducted from the income due to the recipient. In most jurisdictions, tax withholding applies to employment income. Many jurisdictions also require withholding taxes on payments of interest or dividends. In most jurisdictions, there are additional tax withholding obligations if the recipient of the income is resident in a different jurisdiction, and in those circumstances withholding tax sometimes applies to royalties, rent or even the sale of real estate. Governments use tax withholding as a means to combat tax evasion, and sometimes impose additional tax withholding requirements if the recipient has been delinquent in filing tax returns, or in industries where tax evasion is perceived to be common.
In France, taxation is determined by the yearly budget vote by the French Parliament, which determines which kinds of taxes can be levied and which rates can be applied.
For households and individuals, gross income is the sum of all wages, salaries, profits, interest payments, rents, and other forms of earnings, before any deductions or taxes. It is opposed to net income, defined as the gross income minus taxes and other deductions.
The United States federal government and most state governments impose an income tax. They are determined by applying a tax rate, which may increase as income increases, to taxable income, which is the total income less allowable deductions. Income is broadly defined. Individuals and corporations are directly taxable, and estates and trusts may be taxable on undistributed income. Partnerships are not taxed, but their partners are taxed on their shares of partnership income. Residents and citizens are taxed on worldwide income, while nonresidents are taxed only on income within the jurisdiction. Several types of credits reduce tax, and some types of credits may exceed tax before credits. Most business expenses are deductible. Individuals may deduct certain personal expenses, including home mortgage interest, state taxes, contributions to charity, and some other items. Some deductions are subject to limits, and an Alternative Minimum Tax (AMT) applies at the federal and some state levels.

Superannuation in Australia is taxed by the Australian taxation system at three points: on contributions received by a superannuation fund, on investment income earned by the fund, and on benefits paid by the fund.
Due to the absence of the tax code in Argentina, the tax regulation takes place in accordance with separate laws, which, in turn, are supplemented by provisions of normative acts adopted by the executive authorities. The powers of the executive authority include levying a tax on profits, property and added value throughout the national territory. In Argentina, the tax policy is implemented by the Federal Administration of Public Revenue, which is subordinate to the Ministry of Economy. The Federal Administration of Public Revenues (AFIP) is an independent service, which includes: the General Tax Administration, the General Customs Office and the General Directorate for Social Security. AFIP establishes the relevant legal norms for the calculation, payment and administration of taxes:
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.
Taxes in Iceland are levied by the state and the municipalities. Property rights are strong and Iceland is one of the few countries where they are applied to fishery management. Taxpayers pay various subsidies to each other, similar to European countries that are welfare states, but the spending is less than in most European countries. Despite low tax rates in relation to European welfare states, overall taxation and consumption is still much higher than in countries such as Ireland. Employment regulations are relatively flexible. The tax is collected by Skatturinn, the Iceland Revenue and Customs Agency and is due in March each year.
Taxation in Norway is levied by the central government, the county municipality and the municipality. In 2012 the total tax revenue was 42.2% of the gross domestic product (GDP).

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.
Taxation may involve payments to a minimum of two different levels of government: central government through SARS or to local government. Prior to 2001 the South African tax system was "source-based", where in income is taxed in the country where it originates. Since January 2001, the tax system was changed to "residence-based" wherein taxpayers residing in South Africa are taxed on their income irrespective of its source. Non residents are only subject to domestic taxes.
