A Quick Summary to Income Taxes

Income taxes are an essential and complex part of financial management. They form a significant portion of the government’s revenue, which is used to fund public services.

In this article, we will delve into the basics of income taxes and their implications for taxpayers. We will define income taxes, discuss the different types, and explore how they are determined. Additionally, we will dive into tax credits and deductions and how they can lower a taxpayer’s income tax bill.

What Are Income Taxes?

Income taxes are taxes paid by individuals or businesses to the government based on the income they earn over a specified period. The government uses these funds to support social welfare programs, national defense, infrastructure, and other public services.

The Internal Revenue Service (IRS) is the government agency responsible for administering and enforcing federal income tax laws. State governments also levy income taxes, and some local governments may impose income taxes.

Different Types of Income Taxes

There are different types of income taxes, including federal, state, and local taxes.

1. Federal Income Taxes

Federal income taxes are levied by the federal government on all types of income, including wages, salaries, interest, dividends, and capital gains. The federal income tax is a gradual tax, which means that the more income one earns, the higher the percentage of their income they pay in taxes.

2. State Income Taxes

State income taxes are levied by state governments on income earned within the state. Not all states levy income taxes; currently, only 41 states and the District of Columbia impose state income taxes.

3. Local Income Taxes

Some local governments may impose income taxes, such as local wage or earnings taxes. These taxes are most common in large cities, including Philadelphia and New York City.

How Are Income Taxes Determined?

The amount of income tax an individual owes is determined by their income and tax bracket. Taxpayers may check their tax bracket on the IRS website or with a tax professional.

For example, suppose a single taxpayer earns $50,000 per year. In that case, their income would fall within the 22% tax bracket, which means they would owe $6,970 in federal income taxes.

Tax Credits and Deductions

Tax credits and deductions are two methods used to lower an individual’s income tax bill.

1. Tax Credits

Tax credits are a dollar-for-dollar reduction in the amount of taxes owed. There are two types of tax credits: refundable and non-refundable.

Refundable tax credits: These credits can reduce an individual’s tax bill below zero, and the IRS will issue a refund for the excess amount. Examples of refundable tax credits include the Earned Income Tax Credit and the Child Tax Credit.

Non-refundable tax credits: These credits can only reduce an individual’s tax bill to zero. If the credit amount exceeds the amount of income tax owed, the remaining credit is forfeited. Examples of non-refundable tax credits include the Lifetime Learning Credit and the American Opportunity Tax Credit.

2. Deductions

Tax deductions reduce an individual’s taxable income, lowering the amount of tax owed. There are two types of deductions: standard and itemized.

Standard deductions: These deductions are a fixed dollar amount that taxpayers can claim without having to itemize their deductions. The standard deduction amount varies based on the taxpayer’s filing status.

Itemized deductions: These deductions are specific expenses that taxpayers can claim. Examples of itemized deductions include mortgage interest, charitable donations, and medical expenses. Itemized deductions are subject to certain limitations based on income level.

As one of the most contentious issues in modern-day politics, income tax continues to be a hotly debated topic with far-reaching consequences. While a certain segment of the population proverbially breaks out in hives at the thought of paying taxes, there is no denying that income tax is one of the most significant sources of revenue for any government. In this article, we will provide an overview of income tax, its history, types, and how it affects individuals and businesses.

What is income tax?

At its core, income tax is a levy paid by an individual or an entity on any income they earn. The tax payable is usually a percentage of the income earned, either at a fixed rate or a progressive rate. Income tax has been around for centuries, with the earliest recorded instance of a tax on income dating back to ancient Egypt. In modern times, income tax has become an essential source of revenue for governments worldwide. As of 2021, over 150 countries implement income tax.

History of income tax

Income tax as we know it today originated in Britain in 1799, during the Napoleonic Wars. The government of England levied a tax on income to finance the war effort. This tax was later abolished in 1816, but a similar tax was subsequently reintroduced in 1842 to fund other public expenditures. Other countries soon followed Britain’s lead, and an income tax was introduced in the United States during the Civil War in 1862.

Types of income tax

There are generally two types of income tax: progressive and flat tax.

Progressive income tax is a tax levied at a higher rate on high incomes than low incomes. The rationale behind a progressive tax is that those who earn more should pay a higher percentage of their income to contribute their “fair share.” The United States has a progressive income tax system, with higher-income earners paying more taxes than lower-income earners.

On the other hand, a flat tax levies a fixed percentage on all incomes regardless of the amount earned. Many people favor a flat tax since it is considered more equitable and less complex than a progressive tax. One country with a flat tax system is Russia, where an individual pays 13% income tax, regardless of their income level.

How Income tax affects individuals and businesses


One of the most significant effects of income tax on individuals is that it reduces disposable income, which affects an individual’s purchasing power and ultimately their standard of living. Moreover, individuals who earn more are typically liable for a higher income tax rate than those who earn less; these high earners may find it challenging to justify their tax burden, especially if they do not get a commensurate increase in public services. However, income tax enables governments to provide for public goods and services like education, healthcare, infrastructure, and other essential social services.


Income tax has a significant impact on businesses, too. Large corporations usually pay a higher tax rate than small businesses, which could discourage large companies from operating in a particular country. In contrast, small businesses can be more prone to evasion since the taxation process is often complicated and challenging for small business owners. Besides this, income tax has a significant impact on a company’s bottom line since it reduces net profits. Thus, companies with revenue-generating business models tend to be taxed more.


In summary, income tax continues to be a necessary component of modern-day governments. It serves as a significant source of revenue that is essential for using public services, building infrastructure, and financing other developmental projects. While income tax may be unpopular with some citizens, its benefits are undeniable. Despite its numerous challenges, income tax has contributed immensely to the growth and development of many countries worldwide.

Income taxes have been imposed as one avenue for governmental revenue collection in the United States by Congressional legislation and since 1909. Moreover, the ability to require the payment of income taxes by U.S. citizens is provided for by the U.S. Constitution, Article I, Section 8, Clause 1, as might also be referred to as the Taxing and Spending Clause.

This language, as has been later interpreted to pertain to the ability to pass income taxes on U.S. citizens, comprises the phrase that “Duties, Imposts and Excises shall be uniform throughout the United States.” As such, the income tax was first enacted in a permanent form and of the type which still bears on U.S. citizens and residents when Congress determined, in the early 20th century, that the U.S. government was increasingly expensive to administer, and as such enacted the 16th Amendment as well as legislation for the excise tax.
