The United States of America has separate federal, state, and local governments with taxes imposed at each of these levels. Taxes are levied on income, payroll, property, sales, capital gains, dividends, imports, estates and gifts, as well as various fees. In 2020, taxes collected by federal, state, and local governments amounted to 25.5% of GDP, below the OECD average of 33.5% of GDP. The United States had the seventh-lowest tax revenue-to-GDP ratio among OECD countries in 2020, with a higher ratio than Mexico, Colombia, Chile, Ireland, Costa Rica, and Turkey.
Tax deduction is a simplified phrase for meaning income that is able to be taxed and is commonly a result of expenses, particularly those incurred to produce additional income. Tax deductions are a form of tax incentives, along with exemptions and tax credits. The difference between deductions, exemptions, and credits is that deductions and exemptions both reduce taxable income, while credits reduce 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.
A tax treaty, also called double tax agreement (DTA) or double tax avoidance agreement (DTAA), is an agreement between two countries to avoid or mitigate double taxation. Such treaties may cover a range of taxes including income taxes, inheritance taxes, value added taxes, or other taxes. Besides bilateral treaties, multilateral treaties are also in place. For example, European Union (EU) countries are parties to a multilateral agreement with respect to value added taxes under auspices of the EU, while a joint treaty on mutual administrative assistance of the Council of Europe and the Organisation for Economic Co-operation and Development (OECD) is open to all countries. Tax treaties tend to reduce taxes of one treaty country for residents of the other treaty country to reduce double taxation of the same income.
A corporate tax, also called corporation tax or company tax, is a type of direct tax levied on the income or capital of corporations and other similar legal entities. The tax is usually imposed at the national level, but it may also be imposed at state or local levels in some countries. Corporate taxes may be referred to as income tax or capital tax, depending on the nature of the tax.
An ad valorem tax is a tax whose amount is based on the value of a transaction or of a property. It is typically imposed at the time of a transaction, as in the case of a sales tax or value-added tax (VAT). An ad valorem tax may also be imposed annually, as in the case of a real or personal property tax, or in connection with another significant event. In some countries, a stamp duty is imposed as an ad valorem tax.
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.
A use tax is a type of tax levied in the United States by numerous state governments. It is essentially the same as a sales tax but is applied not where a product or service was sold but where a merchant bought a product or service and then converted it for its own use, without having paid tax when it was initially purchased. Use taxes are functionally equivalent to sales taxes. They are typically levied upon the use, storage, enjoyment, or other consumption in the state of tangible personal property that has not been subjected to a sales tax.
A gift tax or known originally as inheritance tax is a tax imposed on the transfer of ownership of property during the giver's life. The United States Internal Revenue Service says that a gift is "Any transfer to an individual, either directly or indirectly, where full compensation is not received in return."
Tax withholding, also known as tax retention, Pay-As-You-Go/Pay-As-You-Earn, tax deduction at source or a Prélèvement à la 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.
Sales taxes in the United States are taxes placed on the sale or lease of goods and services in the United States. Sales tax is governed at the state level and no national general sales tax exists. 45 states, the District of Columbia, the territories of Puerto Rico, and Guam impose general sales taxes that apply to the sale or lease of most goods and some services, and states also may levy selective sales taxes on the sale or lease of particular goods or services. States may grant local governments the authority to impose additional general or selective sales taxes.
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. An alternative tax applies at the federal and some state levels.
International taxation is the study or determination of tax on a person or business subject to the tax laws of different countries, or the international aspects of an individual country's tax laws as the case may be. Governments usually limit the scope of their income taxation in some manner territorially or provide for offsets to taxation relating to extraterritorial income. The manner of limitation generally takes the form of a territorial, residence-based, or exclusionary system. Some governments have attempted to mitigate the differing limitations of each of these three broad systems by enacting a hybrid system with characteristics of two or more.
Corporate tax is imposed in the United States at the federal, most state, and some local levels on the income of entities treated for tax purposes as corporations. Since January 1, 2018, the nominal federal corporate tax rate in the United States of America is a flat 21% following the passage of the Tax Cuts and Jobs Act of 2017. State and local taxes and rules vary by jurisdiction, though many are based on federal concepts and definitions. Taxable income may differ from book income both as to timing of income and tax deductions and as to what is taxable. The corporate Alternative Minimum Tax was also eliminated by the 2017 reform, but some states have alternative taxes. Like individuals, corporations must file tax returns every year. They must make quarterly estimated tax payments. Groups of corporations controlled by the same owners may file a consolidated return.
A foreign tax credit (FTC) is generally offered by income tax systems that tax residents on worldwide income, to mitigate the potential for double taxation. The credit may also be granted in those systems taxing residents on income that may have been taxed in another jurisdiction. The credit generally applies only to taxes of a nature similar to the tax being reduced by the credit and is often limited to the amount of tax attributable to foreign source income. The limitation may be computed by country, class of income, overall, and/or another manner.
The Foreign Investment in Real Property Tax Act of 1980 (FIRPTA), enacted as Subtitle C of Title XI of the Omnibus Reconciliation Act of 1980, Pub. L. No. 96-499, 94 Stat. 2599, 2682, is a United States tax law that imposes income tax on foreign persons disposing of US real property interests. Tax is imposed at regular tax rates for the taxpayer on the amount of gain considered recognized. Purchasers of real property interests are required to withhold tax on payment for the property. Withholding may be reduced from the standard 15% to an amount that will cover the tax liability, upon application in advance of sale to the Internal Revenue Service. FIRPTA overrides most nonrecognition provisions as well as those remaining tax treaties that provide exemption from tax for such gains.
In the United States, the estate tax is a federal tax on the transfer of the estate of a person who dies. The tax applies to property that is transferred by will or, if the person has no will, according to state laws of intestacy. Other transfers that are subject to the tax can include those made through a trust and the payment of certain life insurance benefits or financial accounts. The estate tax is part of the federal unified gift and estate tax in the United States. The other part of the system, the gift tax, applies to transfers of property during a person's life.
The alternative minimum tax (AMT) is a tax imposed by the United States federal government in addition to the regular income tax for certain individuals, estates, and trusts. As of tax year 2018, the AMT raises about $5.2 billion, or 0.4% of all federal income tax revenue, affecting 0.1% of taxpayers, mostly in the upper income ranges.
Most local governments in the United States impose a property tax, also known as a millage rate, as a principal source of revenue. This tax may be imposed on real estate or personal property. The tax is nearly always computed as the fair market value of the property, multiplied by an assessment ratio, multiplied by a tax rate, and is generally an obligation of the owner of the property. Values are determined by local officials, and may be disputed by property owners. For the taxing authority, one advantage of the property tax over the sales tax or income tax is that the revenue always equals the tax levy, unlike the other types of taxes. The property tax typically produces the required revenue for municipalities' tax levies. One disadvantage to the taxpayer is that the tax liability is fixed, while the taxpayer's income is not.
