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 reduction of 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 credits. The difference between deductions, exemptions and credits is that deductions and exemptions both reduce taxable income, while credits reduce tax.
A corporate tax, also called corporation tax or company tax, is a direct tax imposed on the income or capital of corporations or analogous legal entities. Many countries impose such taxes at the national level, and a similar tax may be imposed at state or local levels. The taxes may also be referred to as income tax or capital tax. A country's corporate tax may apply to:
Tax exemption is the reduction or removal of a liability to make a compulsory payment that would otherwise be imposed by a ruling power upon persons, property, income, or transactions. Tax-exempt status may provide complete relief from taxes, reduced rates, or tax on only a portion of items. Examples include exemption of charitable organizations from property taxes and income taxes, veterans, and certain cross-border or multi-jurisdictional scenarios.
Three key types of withholding tax are imposed at various levels in the United States:
The rules governing partnership taxation, for purposes of the U.S. Federal income tax, are codified according to Subchapter K of Chapter 1 of the U.S. Internal Revenue Code. Partnerships are "flow-through" entities. Flow-through taxation means that the entity does not pay taxes on its income. Instead, the owners of the entity pay tax on their "distributive share" of the entity's taxable income, even if no funds are distributed by the partnership to the owners. Federal tax law permits the owners of the entity to agree how the income of the entity will be allocated among them, but requires that this allocation reflect the economic reality of their business arrangement, as tested under complicated rules.
The Modified Accelerated Cost Recovery System (MACRS) is the current tax depreciation system in the United States. Under this system, the capitalized cost (basis) of tangible property is recovered over a specified life by annual deductions for depreciation. The lives are specified broadly in the Internal Revenue Code. The Internal Revenue Service (IRS) publishes detailed tables of lives by classes of assets. The deduction for depreciation is computed under one of two methods at the election of the taxpayer, with limitations. See IRS Publication 946 for a 120-page guide to MACRS.
Tax withholding, also known as tax retention, Pay-as-You-Go, Pay-as-You-Earn, 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.
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.
Income taxes in the United States are imposed by the federal government, and most states. The income taxes 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.
Under U.S. federal tax law, the tax basis of an asset is generally its cost basis. Determining such cost may require allocations where multiple assets are acquired together. Tax basis may be reduced by allowances for depreciation. Such reduced basis is referred to as the adjusted tax basis. Adjusted tax basis is used in determining gain or loss from disposition of the asset. Tax basis may be relevant in other tax computations.
For purposes of income tax in the United States, U.S. persons owning shares of a passive foreign investment company (PFIC) may choose between (i) current taxation on the income of the PFIC or (ii) deferral of such income subject to a deemed tax and interest regime. The provision was enacted as part of the Tax Reform Act of 1986 as a way of placing owners of offshore investment funds on a similar footing to owners of U.S. investment funds. The original provisions applied for all foreign corporations meeting either an income or an asset test. However, 1997 amendments limited the application in the case of U.S. Shareholders of controlled foreign corporations.
Taxpayers in the United States may face various penalties for failures related to Federal, state, and local tax matters. The Internal Revenue Service (IRS) is primarily responsible for charging these penalties at the Federal level. The IRS can assert only those penalties specified imposed under Federal tax law. State and local rules vary widely, are administered by state and local authorities, and are not discussed herein.
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% due to 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.
In United States income tax law, an installment sale is generally a "disposition of property where at least 1 loan payment is to be received after the close of the taxable year in which the disposition occurs." The term "installment sale" does not include, however, a "dealer disposition" or, generally, a sale of inventory. The installment method of accounting provides an exception to the general principles of income recognition by allowing a taxpayer to defer the inclusion of income of amounts that are to be received from the disposition of certain types of property until payment in cash or cash equivalents is received. The installment method defers the recognition of income when compared with both the cash and accrual methods of accounting. Under the cash method, the taxpayer would recognize the income when it is received, including the entire sum paid in the form of a negotiable note. The deferral advantages of the installment method are the most pronounced when comparing to the accrual method, under which a taxpayer must recognize income as soon as he or she has a right to the income.
A Qualified Intermediary refers to a person that acts as an intermediary qualified under certain sections of the U.S. Internal Revenue Code (IRC) to undertake specified activities.
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.
Forms 1042, 1042-S and 1042-T are United States Internal Revenue Service tax forms dealing with payments to foreign persons, including non-resident aliens, foreign partnerships, foreign corporations, foreign estates, and foreign trusts.
