|An aspect of fiscal policy|
In a tax system, the tax rate is the ratio (usually expressed as a percentage) at which a business or person is taxed. There are several methods used to present a tax rate: statutory, average, marginal, and effective. These rates can also be presented using different definitions applied to a tax base: inclusive and exclusive.
A statutory tax rate is the legally imposed rate. An income tax could have multiple statutory rates for different income levels, where a sales tax may have a flat statutory rate.
The statutory tax rate is expressed as a percentage and will always be higher than the effective tax rate.
An average tax rate is the ratio of the total amount of taxes paid to the total tax base (taxable income or spending), expressed as a percentage.
In a proportional tax, the tax rate is fixed and the average tax rate equals this tax rate. In case of tax brackets, commonly used for progressive taxes, the average tax rate increases as taxable income increases through tax brackets, asymptoting to the top tax rate. For example, consider a system with three tax brackets, 10%, 20%, and 30%, where the 10% rate applies to income from $1 to $10,000, the 20% rate applies to income from $10,001 to $20,000, and the 30% rate applies to all income above $20,000. Under this system, someone earning $25,000 would pay $1,000 for the first $10,000 of income (10%); $2,000 for the second $10,000 of income (20%); and $1,500 for the last $5,000 of income (30%). In total, they would pay $4,500, or an 18% average tax rate.
A marginal tax rate is the tax rate on income set at a higher rate for incomes above a designated higher bracket, which in 2016 in the United States was $415,050. For annual income that was above cut off point in that higher bracket, the marginal tax rate in 2016 was 39.6%. For income below the $415,050 cut off, the lower tax rate was 35% or less.
The marginal tax rate on income can be expressed mathematically as follows:
where t is the total tax liability and i is total income, and ∆ refers to a numerical change. In accounting practice, the tax numerator in the above equation usually includes taxes at federal, state, provincial, and municipal levels. Marginal tax rates are applied to income in countries with progressive taxation schemes, with incremental increases in income taxed in progressively higher tax brackets, resulting in the tax burden being distributed amongst those who can most easily afford it.
Marginal taxes are valuable as they allow governments to generate revenue to fund social services in a way that only affects those who will be the least negatively affected.
In economics, one heavily disputed theory is that marginal tax rates will impact the incentive of increased income, meaning that higher marginal tax rates cause individuals to have less incentive to earn more. This is the basis of the Laffer curve theory, which theorizes that population-wide taxable income decreases as a function of the marginal tax rate, making net governmental tax revenues decrease beyond a certain taxation point.[ citation needed ]
With a flat tax, by comparison, all income is taxed at the same percentage, regardless of amount. An example is a sales tax where all purchases are taxed equally. A poll tax is a flat tax of a set dollar amount per person. The marginal tax in these scenarios would be zero, however, these are both forms of regressive taxation and place a higher tax burden on those who are least able to cope with it, and often results in an underfunded government leading to increased deficits.
For individuals who receive means tested benefits, benefits are decreased as more income is earned. This is sometimes described as an implicit tax. [ who? ] argue that these issues create a disincentive for work or promotion and may result in a structural income inequality.[ citation needed ]These implicit marginal tax rates can exceed 90% or even greater than 100%. Some economists
The term effective tax rate has different meanings in different contexts. Generally its calculation attempts to adjust a nominal tax rate to make it more meaningful. It may incorporate econometric, estimated, or assumed adjustments to actual data, or may be based entirely on assumptions or simulations.
The term is used in financial reporting to measure the total tax paid as a percentage of the company's accounting income, instead of as a percentage of the taxable income. International Accounting Standard 12,define it as income tax expense or benefit for accounting purposes divided by accounting profit. In Generally Accepted Accounting Principles (United States), the term is used in official guidance only with respect to determining income tax expense for interim (e.g. quarterly) periods by multiplying accounting income by an "estimated annual effective tax rate", the definition of which rate varies depending on the reporting entity's circumstances.
In U.S. income tax law, the term is used in relation to determining whether a foreign income tax on specific types of income exceeds a certain percentage of U.S. tax that would apply on such income if U.S. tax had been applicable to the income.
The popular press, Congressional Budget Office, and various think tanks have used the term to mean varying measures of tax divided by varying measures of income, with little consistency in definition.
Investors usually modify a statutory marginal tax rate to create the effective tax rate appropriate for their decision.
For example: If capital gains are only taxed when realized by a sale, the effective tax rate is the yearly rate that would have applied to the average yearly gain so that the resulting after-tax profit is the same as when all taxed at statutory rates on sale. It will be lower than the statutory rate because unrealized profits are reinvested without tax.
For example: When dividends are both taxed as income, and also generate a tax credit in the UK and Canadian system, the effective tax rate is the net effect of both - the net tax divided by the actual dividend's value.
For example: When contributions are made to Tax Deferred Accounts the reduced tax base will result in reduced taxes calculated at the statutory marginal rate. But the reduction in the tax base may also affect qualification for other government benefits. The difference in those benefits is added to the numerator to increase the effective marginal rate due to the contribution.
Tax rates can be presented differently due to differing definitions of tax base, which can make comparisons between tax systems confusing.
Some tax systems include the taxes owed in the tax base (tax-inclusive, Before Tax), while other tax systems do not include taxes owed as part of the base (tax-exclusive, After Tax).In the United States, sales taxes are usually quoted exclusively and income taxes are quoted inclusively. The majority of Europe, value added tax (VAT) countries, include the tax amount when quoting merchandise prices, including Goods and Services Tax (GST) countries, such as Australia and New Zealand. However, those countries still define their tax rates on a tax exclusive basis.
For direct rate comparisons between exclusive and inclusive taxes, one rate must be manipulated to look like the other. When a tax system imposes taxes primarily on income, the tax base is a household's pre-tax income. The appropriate income tax rate is applied to the tax base to calculate taxes owed. Under this formula, taxes to be paid are included in the base on which the tax rate is imposed. If an individual's gross income is $100 and income tax rate is 20%, taxes owed equals $20.
The income tax is taken "off the top", so the individual is left with $80 in after-tax money. Some tax laws impose taxes on a tax base equal to the pre-tax portion of a good's price. Unlike the income tax example above, these taxes do not include actual taxes owed as part of the base. A good priced at $80 with a 25% exclusive sales tax rate yields $20 in taxes owed. Since the sales tax is added "on the top", the individual pays $20 of tax on $80 of pre-tax goods for a total cost of $100. In either case, the tax base of $100 can be treated as two parts—$80 of after-tax spending money and $20 of taxes owed. A 25% exclusive tax rate approximates a 20% inclusive tax rate after adjustment.By including taxes owed in the tax base, an exclusive tax rate can be directly compared to an inclusive tax rate.
A tax is a compulsory financial charge or some other type of levy imposed upon a taxpayer by a governmental organization in order to fund various public expenditures. A failure to pay, along with evasion of or resistance to taxation, is punishable by law. Taxes consist of direct or indirect taxes and may be paid in money or as its labour equivalent. The first known taxation took place in Ancient Egypt around 3000–2800 BC.
A flat tax is a tax system with a constant marginal rate, usually applied to individual or corporate income. A true flat tax would be a proportional tax, but implementations are often progressive and sometimes regressive depending on deductions and exemptions in the tax base. There are various tax systems that are labeled "flat tax" even though they are significantly different.
In finance, the net present value (NPV) or net present worth (NPW) applies to a series of cash flows occurring at different times. The present value of a cash flow depends on the interval of time between now and the cash flow. It also depends on the discount rate. NPV accounts for the time value of money. It provides a method for evaluating and comparing capital projects or financial products with cash flows spread over time, as in loans, investments, payouts from insurance contracts plus many other applications.
A progressive tax is a tax in which the tax rate increases as the taxable amount increases. The term "progressive" refers to the way the tax rate progresses from low to high, with the result that a taxpayer's average tax rate is less than the person's marginal tax rate. The term can be applied to individual taxes or to a tax system as a whole; a year, multi-year, or lifetime. Progressive taxes are imposed in an attempt to reduce the tax incidence of people with a lower ability to pay, as such taxes shift the incidence increasingly to those with a higher ability-to-pay. The opposite of a progressive tax is a regressive tax, where the average tax rate or burden decreases as an individual's ability to pay increases.
Payroll taxes are taxes imposed on employers or employees, and are usually calculated as a percentage of the salaries that employers pay their staff. Payroll taxes generally fall into two categories: deductions from an employee’s wages, and taxes paid by the employer based on the employee's wages. The first kind are taxes that employers are required to withhold from employees' wages, also known as withholding tax, pay-as-you-earn tax (PAYE), or pay-as-you-go tax (PAYG) and often covering advance payment of income tax, social security contributions, and various insurances. The second kind is a tax that is paid from the employer's own funds and that is directly related to employing a worker. These can consist of fixed charges or be proportionally linked to an employee's pay. The charges paid by the employer usually cover the employer's funding of the social security system, medicare, and other insurance programs. It is sometimes claimed that the economic burden of the payroll tax falls almost entirely on the worker, regardless of whether the tax is remitted by the employer or the employee, as the employers’ share of payroll taxes is passed on to employees in the form of lower wages than would otherwise be paid. 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.
FairTax is a proposal to reform the federal tax code of the United States. It would replace all federal income taxes, payroll taxes, gift taxes, and estate taxes with a single broad national consumption tax on retail sales. The Fair Tax Act would apply a tax, once, at the point of purchase on all new goods and services for personal consumption. The proposal also calls for a monthly payment to all family households of lawful U.S. residents as an advance rebate, or "prebate", of tax on purchases up to the poverty level. First introduced into the United States Congress in 1999, a number of congressional committees have heard testimony on the bill; however, it has not moved from committee and has yet to have any effect on the tax system. In 2005, a tax reform movement began to form behind the FairTax proposal. Attention increased after talk radio personality Neal Boortz and Georgia Congressman John Linder published The FairTax Book in 2005 and additional visibility was gained in the 2008 presidential campaign.
Tax brackets are the divisions at which tax rates change in a progressive tax system. Essentially, they are the cutoff values for taxable income—income past a certain point will be taxed at a higher rate.
In business, operating margin—also known as operating income margin, operating profit margin, EBIT margin and return on sales (ROS)—is the ratio of operating income to net sales, usually presented in percent.
Operating leverage is a measure of how revenue growth translates into growth in operating income. It is a measure of leverage, and of how risky, or volatile, a company's operating income is.
In corporate finance, the return on equity (ROE) is a measure of the profitability of a business in relation to the equity, also known as net assets or assets minus liabilities. ROE is a measure of how well a company uses investments to generate earnings growth.
In investing, the cash-on-cash return is the ratio of annual before-tax cash flow to the total amount of cash invested, expressed as a percentage.
In finance, return is a profit on an investment. It comprises any change in value of the investment, and/or cash flows which the investor receives from the investment, such as interest payments or dividends. It may be measured either in absolute terms or as a percentage of the amount invested. The latter is also called the holding period return.
For the Old Age, Survivors and Disability Insurance (OASDI) tax or Social Security tax in the United States, the Social Security Wage Base (SSWB) is the maximum earned gross income or upper threshold on which a wage earner's Social Security tax may be imposed. The Social Security tax is one component of the Federal Insurance Contributions Act tax (FICA) and Self-employment tax, the other component being the Medicare tax. It is also the maximum amount of covered wages that are taken into account when average earnings are calculated in order to determine a worker's Social Security benefit.
The Fair Tax Act is a bill in the United States Congress for changing tax laws to replace the Internal Revenue Service (IRS) and all federal income taxes, payroll taxes, corporate taxes, capital gains taxes, gift taxes, and estate taxes with a national retail sales tax, to be levied once at the point of purchase on all new goods and services. The proposal also calls for a monthly payment to households of citizens and legal resident aliens as an advance rebate of tax on purchases up to the poverty level. The impact of the FairTax on the distribution of the tax burden is a point of dispute. The plan's supporters argue that it would decrease tax burdens, broaden the tax base, be progressive, increase purchasing power, and tax wealth, while opponents argue that a national sales tax would be inherently regressive and would decrease tax burdens paid by high-income individuals.
Tax deferral refers to instances where a taxpayer can delay paying taxes to some future period. In theory, the net taxes paid should be the same. Taxes can sometimes be deferred indefinitely, or may be taxed at a lower rate in the future, particularly for deferral of income taxes.
The marriage penalty in the United States refers to the higher taxes required from some married couples with both partners earning income that would not be required by two otherwise identical single people with exactly the same incomes. There is also a marriage bonus that applies in other cases. Multiple factors are involved, but in general, in the current U.S. system, single-income married couples usually benefit from filing as a married couple, while dual-income married couples are often penalized. The percentage of couples affected has varied over the years, depending on shifts in tax rates.
A financial ratio or accounting ratio is a relative magnitude of two selected numerical values taken from an enterprise's financial statements. Often used in accounting, there are many standard ratios used to try to evaluate the overall financial condition of a corporation or other organization. Financial ratios may be used by managers within a firm, by current and potential shareholders (owners) of a firm, and by a firm's creditors. Financial analysts use financial ratios to compare the strengths and weaknesses in various companies. If shares in a company are traded in a financial market, the market price of the shares is used in certain financial ratios.
In general, the United States federal income tax is progressive, as rates of tax generally increase as taxable income increases, at least with respect to individuals that earn wage income. As a group, the lowest earning workers, especially those with dependents, pay no income taxes and may actually receive a small subsidy from the federal government.
Tax policy and economic inequality in the United States discusses how tax policy affects the distribution of income and wealth in the United States. Income inequality can be measured before- and after-tax; this article focuses on the after-tax aspects. Income tax rates applied to various income levels and tax expenditures primarily drive how market results are redistributed to impact the after-tax inequality. After-tax inequality has risen in the United States markedly since 1980, following a more egalitarian period following World War II.
The Common Consolidated Corporate Tax Base (CCCTB) is a proposal for a common tax scheme for the European Union developed by the European Commission and first proposed in March 2011 that provides a single set of rules for how EU corporations calculate EU taxes, and provide the ability to consolidate EU taxes. Corporate tax rates in the EU would not be changed by the CCCTB, as EU countries would continue to have their own corporate tax rates.
