# Understanding Taxation: Definitions, Justifications, and Types

## What Is Taxation?

Taxation refers to the compulsory levies imposed by governments on their citizens. These levies have existed since ancient times, serving as a fundamental mechanism to fund public services and infrastructure. They encompass various types, such as income, capital gains, and [estate taxes](https://www.investopedia.com/terms/e/estatetax.asp).

While "taxation" can be a noun or verb, it primarily denotes the act of imposing these financial obligations, with the objective of generating revenue for governmental expenditure.

## Understanding Taxation

Taxation differs from other payments, like market exchanges, as it does not require consent and isn't directly linked to services provided. Governments enforce taxation through either implied or direct threats of force. Taxation is legally different than extortion or a protection [racket](https://www.investopedia.com/terms/r/racketeering.asp) because the imposing institution is a government, not private actors.

Tax systems have varied greatly across different places and times. In most modern tax systems, taxation applies to physical [assets](https://www.investopedia.com/terms/a/asset.asp) like property and events like sales transactions. Creating tax policies is a critical and often debated issue in modern politics.

##  A Historical Overview of Taxation in the United States

The U.S. government was originally funded on very little direct taxation. Instead, federal agencies charged [user fees](https://www.investopedia.com/terms/u/user-fee.asp) for ports and other government properties. In times of need, the government would decide to sell government assets and [bonds](https://www.investopedia.com/terms/b/bond.asp) or issue an assessment to the states for services rendered. Thomas Jefferson abolished direct taxes in 1802, and only [excise taxes](https://www.investopedia.com/terms/e/excisetax.asp) remained until Congress repealed them in 1817. Between 1817 and 1861, the federal government collected no internal revenue.

An income tax of 3% was levied on high-income earners during the Civil War. The federal government began taxing income regularly only after the Sixteenth Amendment was ratified in 1913. As of 2024, U.S. taxation applies to a wide range of items or activities, from income to cigarette and gasoline purchases to inheritances and when winning at a casino or even Nobel Prize.

## The Purposes and Justifications Behind Taxation

The most basic function of taxation is to fund government expenditures. Throughout history, various reasons and justifications for taxes have been offered. Early taxes funded ruling classes, supported armies, and built defenses. Often, the authority to tax stemmed from divine or supranational rights.

Later justifications have been offered across utilitarian, economic, or moral considerations. Proponents of [progressive levels of taxation](https://www.investopedia.com/terms/p/progressivetax.asp) on high-income earners argue that taxes encourage a more equitable society. Higher taxes on specific products and services, such as tobacco or gasoline, have been justified as a deterrent to consumption. Advocates of public goods theory argue taxes may be necessary in cases in which the private provision of public goods is considered sub-optimal, such as with lighthouses or national defense.

## Exploring Various Types of Taxation

As mentioned above, taxation applies to all different types of levies. These can include (but are not limited to):

*   **Income tax**: Governments impose income taxes on financial income generated by all entities within their jurisdiction, including individuals and businesses.
*   **Corporate tax**: This type of tax is imposed on the profit of a business.
*   **Capital gains**: A tax on capital gains is imposed on any capital gains or profits made by people or businesses from the sale of certain assets including stocks, bonds, or real estate. 
*   **Property tax**: A property tax is asses by a local government and paid for by the owner of a property. This tax is calculated based on property and land values. 
*   **Inheritance**: A type of tax levied on individuals who inherit the estate of a deceased person. 
*   **Sales tax**: A consumption tax imposed by a government on the sale of goods and services. This can take the form of a value-added tax (VAT), a goods and services tax (GST), a state or provincial sales tax, or an excise tax. 

## Why Do We Need to Pay Taxes?

There is an old saying that goes "the only sure things in life are death and taxes." Taxation has been a feature of society going back to ancient times. The role of taxes is to help governments fund various undertakings such as public works, infrastructure, and wars. Today, taxpayer dollars are still used for a variety of similar purposes.
