Horizontal and Vertical Equity Definition

An explanation of the difference between horizontal and vertical equity.

horizontal-vertical-equity

Horizontal equity implies that we give the same treatment to people in an identical situation. E.g. if two people earn £15,000 they should both pay the same amount of income tax (e.g. £2,500). Horizontal equity makes sure we don’t have discrimination on the grounds such as race/gender/different types of work. Horizontal equity also requires a tax system which doesn’t give preferential treatment to certain individuals/companies.

Vertical equity Vertical equity is concerned with redistributing income within society. It implies that people with higher incomes should pay more tax. Vertical equity requires proportional or progressive taxes. For example, income tax helps improve vertical equity by taxing according to how much people earn. High-income earners may a higher proportion of their income in tax. (See: progressive tax)

Horizontal equity is an important starting point for any tax system. Horizontal equity can be consistent with also achieving vertical equity. Horizontal equity is the equal treatment of equals, and this is a means of achieving a distribution of tax burdens that is vertically equitable.

Example of tax

The Poll Tax is an example of a tax that has horizontal equity (everyone pays a lump sum of £500 a year). Mrs Thatcher’s theory was that since everyone had the same access to council services everyone should pay the same tax.

However, the poll tax does not meet the criteria for vertical equity. For those on low incomes, the poll tax was a high % of their disposable income. For those on high incomes and more ability to pay it was a low %.

Horizontal inequality

Complicated tax systems with loopholes can give certain types of individuals/companies preferential tax rates. For example, if you are self-employed, you will pay national insurance contributions. However, if you set up a company and pay yourself dividends – profit. Then in the UK this gets taxed at a lower rate. Company tax is lower than personal tax rates. By switching from self-employment to a limited company, the tax bill is lower.

US corporation tax loopholes

In the US, certain companies can get tax loopholes related to the industry. For example, if a US company sells goods in a foreign country, these sales are not taxes. But, this means some companies can artificially inflate their foreign sales by running inventories through foreign accounts, reducing tax bill compared to companies who don’t side-track profit through foreign companies.
