A tax is a mandatory financial charge or levy imposed on a taxpayer by a governmental organization to support government spending and public expenditures collectively or to regulate and reduce negative externalities. Tax compliance refers to policy actions and individual behavior 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 occurred in Ancient Egypt around 3000–2800 BC. Taxes consist of direct or indirect taxes and may be paid in money or as labor equivalent.
Public finance refers to the monetary resources available to governments and also to the study of finance within government and role of the government in the economy. As a subject of study, it is the branch of economics which 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 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.
In Canada, taxation is a prerogative shared between the federal government and the various provincial and territorial legislatures.
In the United Kingdom, taxation may involve payments to at least three different levels of government: central government, devolved governments and local government. Central government revenues come primarily from income tax, National Insurance contributions, value added tax, corporation tax and fuel duty. Local government revenues come primarily from grants from central government funds, business rates in England, Council Tax and increasingly from fees and charges such as those for on-street parking. In the fiscal year 2023–24, total government revenue was forecast to be £1,139.1 billion, or 40.9 per cent of GDP, with income taxes and National Insurance contributions standing at around £470 billion.
A tax refund is a payment to the taxpayer due because the taxpayer has paid more tax than owed.
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.
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.

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.
