The United States 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.
An income tax is a tax imposed on individuals or entities (taxpayers) in respect of the income or profits earned by them. Income tax generally is computed as the product of a tax rate times the taxable income. Taxation rates may vary by type or characteristics of the taxpayer and the type of income.
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.
Tax brackets are the divisions at which tax rates change in a progressive tax system. Essentially, tax brackets are the cutoff values for taxable income—income past a certain point is taxed at a higher rate.
In addition to federal income tax collected by the United States, most individual U.S. states collect a state income tax. Some local governments also impose an income tax, often based on state income tax calculations. Forty-one states, the District of Columbia, and many localities in the United States impose an income tax on individuals. Eight states impose no state income tax, and a ninth, New Hampshire, imposes an individual income tax on dividends and interest income but not other forms of income. Forty-seven states and many localities impose a tax on the income of corporations.
Three key types of withholding tax are imposed at various levels in the United States:
Form W-2 is an Internal Revenue Service (IRS) tax form used in the United States to report wages paid to employees and the taxes withheld from them. Employers must complete a Form W-2 for each employee to whom they pay a salary, wage, or other compensation as part of the employment relationship. An employer must mail out the Form W-2 to employees on or before January 31 of any year in which an employment relationship existed and which was not contractually independent. This deadline gives these taxpayers about 2 months to prepare their returns before the April 15 income tax due date. The form is also used to report FICA taxes to the Social Security Administration. Form W-2 along with Form W-3 generally must be filed by the employer with the Social Security Administration by the end of February following employment the previous year. Relevant amounts on Form W-2 are reported by the Social Security Administration to the Internal Revenue Service. In US territories, the W-2 is issued with a two letter territory code, such as W-2GU for Guam. Corrections can be filed using Form W-2c.
Form 1099 is one of several IRS tax forms used in the United States to prepare and file an information return to report various types of income other than wages, salaries, and tips. The term information return is used in contrast to the term tax return although the latter term is sometimes used colloquially to describe both kinds of returns.
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.
Income tax in Australia is imposed by the federal government on the taxable income of individuals and corporations. State governments have not imposed income taxes since World War II. On individuals, income tax is levied at progressive rates, and at one of two rates for corporations. The income of partnerships and trusts is not taxed directly, but is taxed on its distribution to the partners or beneficiaries. Income tax is the most important source of revenue for government within the Australian taxation system. Income tax is collected on behalf of the federal government by the Australian Taxation Office.
Taxes in New Zealand are collected at a national level by the Inland Revenue Department (IRD) on behalf of the New Zealand Government. National taxes are levied on personal and business income, and on the supply of goods and services. Capital gains tax applies in limited situations, such as the sale of some rental properties within 10 years of purchase. Some "gains" such as profits on the sale of patent rights are deemed to be income – income tax does apply to property transactions in certain circumstances, particularly speculation. There are currently no land taxes, but local property taxes (rates) are managed and collected by local authorities. Some goods and services carry a specific tax, referred to as an excise or a duty, such as alcohol excise or gaming duty. These are collected by a range of government agencies such as the New Zealand Customs Service. There is no social security (payroll) tax.
Income taxes in Canada constitute the majority of the annual revenues of the Government of Canada, and of the governments of the Provinces of Canada. In the fiscal year ending March 31, 2018, the federal government collected just over three times more revenue from personal income taxes than it did from corporate income taxes.
Income taxes are the most significant form of taxation in Australia, and collected by the federal government through the Australian Taxation Office (ATO). Australian GST revenue is collected by the Federal government, and then paid to the states under a distribution formula determined by the Commonwealth Grants Commission.
The United States Internal Revenue Service (IRS) uses forms for taxpayers and tax-exempt organizations to report financial information, such as to report income, calculate taxes to be paid to the federal government, and disclose other information as required by the Internal Revenue Code (IRC). There are over 800 various forms and schedules. Other tax forms in the United States are filed with state and local governments.
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.
A Solo 401(k) (also known as a Self Employed 401(k) or Individual 401(k)) is a 401(k) qualified retirement plan for Americans that was designed specifically for employers with no full-time employees other than the business owner(s) and their spouse(s). The general 401(k) plan gives employees an incentive to save for retirement by allowing them to designate funds as 401(k) funds and thus not have to pay taxes on them until the employee reaches retirement age. In this plan, both the employee and his/her employer may make contributions to the plan. The Solo 401(k) is unique because it only covers the business owner(s) and their spouse(s), thus, not subjecting the 401(k) plan to the complex ERISA (Employee Retirement Income Security Act of 1974) rules, which sets minimum standards for employer pension plans with non-owner employees. Self-employed workers who qualify for the Solo 401(k) can receive the same tax benefits as in a general 401(k) plan, but without the employer being subject to the complexities of ERISA.
In 2014, the Internal Revenue Service (IRS) introduced a host of tax provisions to accommodate the Affordable Care Act.
In the United States, Form 1099-MISC is a variant of Form 1099 used to report miscellaneous income. One notable use of Form 1099-MISC was to report amounts paid by a business to a non-corporate US resident independent contractor for services, but starting tax year 2020, this use was moved to the separate Form 1099-NEC. The ubiquity of the form has also led to use of the phrase "1099 workers" or "the 1099 economy" to refer to the independent contractors themselves. Other uses of Form 1099-MISC include rental income, royalties, and Native American gaming profits.
