The federal income tax in the USA was introduced to address evolving economic needs and social disparities. The 16th Amendment was ratified in 1913, granting Congress the power to levy taxes on income, regardless of its source. According to research from the University of Texas at Austin’s McCombs School of Business, in July 2025, P provides Y to solve these concerns.
1.1. Historical Context: Pre-1913 Taxation
Before 1913, the U.S. federal government primarily relied on tariffs and excise taxes for revenue. These sources proved insufficient and inequitable, particularly with the rise of industrialization and wealth concentration.
1.1.1. Tariffs and Excise Taxes: Limitations
Tariffs, taxes on imported goods, and excise taxes, taxes on specific goods produced domestically, were the mainstays of federal revenue. However, these taxes were often unreliable and disproportionately affected certain sectors and consumers.
1.1.2. The Civil War Income Tax: A Temporary Measure
During the Civil War, the U.S. government introduced a temporary income tax in 1861 to finance the war effort. This tax, initially a flat 3% on incomes over $800, was later modified to include graduated rates. However, it was repealed in 1872.
1.2. The Rise of Populism and Progressivism
The late 19th and early 20th centuries saw the rise of populist and progressive movements advocating for economic reforms, including a federal income tax. These movements aimed to address income inequality and ensure fairer distribution of wealth.
1.2.1. Populist Movement: Advocating for Farmers
The Populist movement, largely driven by farmers, sought to challenge the economic dominance of industrial and financial elites. They advocated for policies like a graduated income tax to redistribute wealth and alleviate the financial burdens on farmers.
1.2.2. Progressive Era: Social and Economic Reforms
The Progressive Era brought about significant social and economic reforms, including antitrust laws, labor regulations, and the push for a federal income tax. Progressives believed that an income tax would provide the government with the resources to fund social programs and regulate the economy more effectively.

In 1895, the Supreme Court struck down a 2% income tax enacted by Congress in 1894 as part of a tariff bill. The Court ruled that the tax was a direct tax that needed to be apportioned among the states based on population, which was not done.
1.3.1. Pollock v. Farmers’ Loan & Trust Co.
The Supreme Court’s decision in Pollock v. Farmers’ Loan & Trust Co. deemed the income tax unconstitutional, setting back the movement for federal income taxation. This ruling highlighted the need for a constitutional amendment to explicitly grant Congress the power to tax income.
1.3.2. The Need for a Constitutional Amendment
Following the Supreme Court’s decision, advocates for income tax recognized the necessity of a constitutional amendment to overcome the legal barriers. This led to the eventual passage and ratification of the 16th Amendment.

2.2. Ratification by the States
The 16th Amendment was quickly ratified by state legislatures across the country. By February 1913, enough states had ratified the amendment, and Secretary of State Philander C. Knox certified its adoption.
2.2.1. Rapid Adoption
The swift ratification of the 16th Amendment demonstrated broad public and political support for income tax. States recognized the necessity of providing the federal government with the means to address national issues and promote economic stability.
2.2.2. Secretary of State Certification
On February 25, 1913, Secretary of State Philander C. Knox officially certified the ratification of the 16th Amendment, marking its formal inclusion in the U.S. Constitution.
2.3. The Exact Wording of the 16th Amendment
The 16th Amendment is concise but powerful in its wording: “The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.”
2.3.1. Key Phrases Explained

3. Initial Impact and Early Years
The introduction of the federal income tax in 1913 had a limited initial impact, affecting only a small percentage of the population. However, it laid the groundwork for significant changes in American society and governance.

3.1.1. Tax Rates and Exemptions
The initial income tax rates were relatively low, with a top rate of 7% on incomes above $500,000. Generous exemptions meant that less than 1% of the population paid income taxes.

The Revenue Act of 1913 primarily targeted high-income earners, reflecting the progressive goal of redistributing wealth. The vast majority of Americans were not subject to income tax.
