Demystifying Progressive Taxation: A Fair Approach to Income Taxation


A progressive tax is a taxation system where tax rates increase as taxable income rises. It aims to impose a lower tax burden on low-income individuals and a higher one on those with higher incomes. This is achieved through the creation of tax brackets that categorize taxpayers by their income levels. The United States employs a progressive tax system, although it has become somewhat flatter over the years. In 2022 and 2023, it features seven tax brackets with rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37%, a significant shift from the 16 tax brackets in 1985.

Understanding progressive tax

A progressive tax system is a cornerstone of modern tax policy, designed to address income inequality and distribute the tax burden fairly. Let’s delve deeper into its key aspects:

The progression of tax rates

Progressive tax systems are characterized by their tiered structure of tax rates. The fundamental idea is that as individuals earn more income, they pay a higher percentage of that income in taxes. This structure is in stark contrast to a flat tax, where everyone pays the same percentage, regardless of income.

In the United States, for instance, taxpayers are placed into one of several tax brackets, each with its own rate. In the tax years 2022 and 2023, these rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%, based on the taxpayer’s income level.


Here is a list of the advantages and disadvantages of a progressive tax system to consider.

  • Income Equality: Progressive taxation aims to reduce income inequality by ensuring that those with lower incomes pay a smaller portion of their earnings in taxes.
  • Economic Stimulus: By putting more money into the pockets of low-income earners, progressive tax systems can boost consumer spending, fueling economic growth.
  • Increased Government Revenue: A higher percentage of taxes is collected from those with higher incomes, contributing to government revenue and funding essential public services.
  • Incentive Debate: Critics argue that high tax rates on the wealthy can discourage investment and entrepreneurial endeavors, potentially slowing economic growth.
  • Complexity: Progressive tax systems can be complex, with numerous tax brackets and calculations, which may pose challenges for taxpayers.

Progressive tax vs. regressive tax

Understanding different tax systems is essential to grasp the nuances of how governments collect revenue. Two primary tax systems are progressive and regressive taxation, each with distinct features and implications for individuals and society.
Progressive tax: As previously discussed, a progressive tax system is designed to address income inequality by imposing higher tax rates on those with higher incomes. This means that as individuals earn more money, they contribute a larger portion of their income to taxes. The underlying philosophy is one of fairness, aiming to ensure that the tax burden aligns with a taxpayer’s ability to pay. In this system, the tax rate increases as income rises, making it particularly beneficial for lower-income individuals.

Regressive tax: In contrast, a regressive tax system collects a higher percentage of income from low-wage earners compared to high-wage earners. Imagine a sales tax on goods and services where everyone pays the same fixed tax rate, regardless of their income level. This means that individuals with lower incomes spend a more substantial portion of their earnings on these taxes, which can lead to an unequal tax burden. Regressive taxes tend to affect lower-income individuals disproportionately.

Progressive tax vs. flat tax

Another critical comparison in the world of taxation is between progressive and flat tax systems. These two systems vary significantly in how they distribute the tax burden among citizens.
Progressive tax: As previously explained, a progressive tax system adjusts tax rates based on income levels. This ensures that individuals with higher incomes contribute a greater portion of their earnings to taxes. It’s often viewed as a mechanism to promote income equality and address societal disparities. In the United States, for example, the tax brackets set by the government dictate how much individuals owe in taxes based on their income.

Flat tax: In contrast, a flat tax system is characterized by a uniform tax rate that applies to all taxpayers, regardless of their income. In a flat tax system, everyone pays the same percentage of their earnings in taxes. While the United States incorporates elements of a flat tax in its Social Security payroll tax, there is an income cap that limits the amount of income subject to this tax. Flat tax systems can simplify tax calculations but may lead to debates about fairness, as everyone pays the same percentage, regardless of their financial situation.

Income tax calculation in a progressive system

Understanding how income taxes are calculated within a progressive system is essential to comprehend how individuals are taxed based on their earnings. Let’s illustrate this with an example:
Consider a single person who earns $100,000 in the tax year 2022. This income places them in the 24% tax bracket. However, it’s important to note that not all of their income is taxed at this rate. In a progressive system, specific income thresholds determine tax rates. For instance, only the portion of their income exceeding $89,075 is taxed at the 24% rate, while the rest of their income is taxed at lower rates, as dictated by their respective tax brackets. This tiered approach ensures that individuals are taxed fairly, with higher rates applying only to higher portions of their income.

Changes in tax brackets

Tax brackets are not fixed and can change over time due to legislative actions. In the United States, Congress holds the authority to set these brackets, enabling adjustments in tax rates and income thresholds as needed. For example, the Tax Cuts and Jobs Act of 2017 retained seven tax brackets but lowered rates for many taxpayers. Such changes aim to align the tax system with economic conditions, revenue requirements, and broader fiscal goals.

The purpose of a progressive tax

Progressive taxation serves a crucial purpose within government finance, and understanding its role is essential. Its primary goal is to ensure that the burden of financing government services, oversight, and infrastructure does not disproportionately fall on lower-income individuals. By taxing higher incomes at a higher rate, progressive taxation enables the collection of more tax revenue, which, in turn, supports critical public services.
This system acknowledges the principle of ability to pay, meaning that those with higher incomes can afford to contribute more to the common good. The revenue generated from progressive taxation helps fund essential services like education, healthcare, infrastructure development, and social safety nets, contributing to the overall well-being of society.


In summary, a progressive tax system is a fundamental component of modern taxation, designed to address income inequality and distribute the tax burden fairly. It employs tiered tax rates that increase with income, ensuring that lower-income individuals pay a smaller percentage of their earnings in taxes. In the United States, this system involves seven tax brackets with rates ranging from 10% to 37% for the tax years 2022 and 2023. While the rates remained stable, adjustments were made to the income ranges within each bracket to account for inflation.
