Taxes on Americans started in 1733, when the British Parliament imposed the Molasses Act on the colonies. Domestically, the federal government has had the power to tax since the Constitution took effect in 1789, it collected its first internal excise tax in 1791, imposed its first income tax during the Civil War in 1861, and launched the modern income tax in 1913 after the 16th Amendment was ratified. So when taxes started in America depends on which tax you mean.
The First Taxes on Americans Came From Britain
The earliest taxes affecting people living in what would become the United States were imposed by Parliament, not by any American government. The Molasses Act of 1733 put a duty of six pence per gallon on molasses imported into British colonies from foreign sugar plantations in the Caribbean.1The Statutes Project. 1733: 6 George 2 c.13: The Molasses Act Enforcement was loose, and colonial merchants largely evaded it for decades.
After the French and Indian War, Britain got serious. The Sugar Act of 1764 cut the molasses duty to three pence per gallon but backed it with real enforcement.2National Park Service. Britain Begins Taxing the Colonies: The Sugar and Stamp Acts The Stamp Act of 1765 went further, requiring colonists to buy revenue stamps for legal documents, newspapers, and playing cards.3Avalon Project. Great Britain: Parliament – The Stamp Act, 1765 The rallying cry “taxation without representation” grew from these levies and helped push the colonies toward independence.
The Federal Government’s Power to Tax Began in 1789
The Articles of Confederation gave Congress no power to tax, and the new government quickly went broke. The Constitution of 1789 fixed that. Article I, Section 8 gave Congress the power to lay and collect taxes, duties, and excises to pay debts and provide for the common defense.4Constitution Annotated. Article I – Legislative Branch
For the first few years, federal revenue came almost entirely from tariffs on imported goods. Then in 1791, Treasury Secretary Alexander Hamilton pushed Congress to pass the country’s first internal excise tax, a levy on distilled spirits. It was the first federal tax on something produced domestically rather than imported.5United States House of Representatives: History, Art, and Archives. The 1791 Excise Whiskey Tax It hit frontier farmers hardest, and by 1794 the Whiskey Rebellion in western Pennsylvania forced Washington to send in militia to enforce collection.6Alcohol and Tobacco Tax and Trade Bureau.

The First Federal Income Tax Was a Civil War Measure
For the first seven decades of the republic, the federal government did not tax people’s earnings directly. The Constitution required any “direct tax” to be apportioned among the states by population, which made a nationwide income tax impractical.7Constitution Annotated. ArtI.S9.C4.1 Overview of Direct Taxes Tariffs and excise taxes covered federal needs until the Civil War blew that budget apart.
The Revenue Act of 1861 imposed the country’s first income tax: a flat 3% on annual incomes above $800.8United States Senate. The Civil War: The Senate’s Story The Revenue Act of 1862 replaced it with a graduated structure of 3% on incomes between $600 and $10,000 and 5% above $10,000, and it created the Office of the Commissioner of Internal Revenue, the ancestor of today’s IRS. That same 1862 law also introduced the country’s first inheritance tax.9Internal Revenue Service. Historical Highlights of the IRS
The wartime income tax was always meant to be temporary. Congress repealed it in 1872. For the next four decades, roughly 90% of federal revenue came from excise taxes on alcohol and tobacco.9Internal Revenue Service. Historical Highlights of the IRS
The Modern Income Tax Dates to 1913
Congress tried to bring the income tax back in 1894, but the Supreme Court struck it down. In Pollock v. Farmers’ Loan & Trust Co. (1895), the Court held that a tax on income from property was a direct tax that had to be apportioned among the states by population, which effectively killed any workable federal income tax.10Justia. Pollock v. Farmers’ Loan and Trust Co.
Fixing that required amending the Constitution. Congress proposed the 16th Amendment in 1909, and it was ratified on February 3, 1913. Its language is short: Congress has the power to tax incomes “from whatever source derived, without apportionment among the several States.”11Constitution Annotated. U.S. Constitution – Sixteenth Amendment
The Revenue Act of 1913 followed within months. It set up a graduated income tax starting at 1%, with exemptions generous enough that less than 1% of Americans owed anything.12National Archives. 16th Amendment to the U.S. Constitution: Federal Income Tax The income tax began as a tax on the wealthy. World War I pushed the top marginal rate to 77% by 1918, and rates fell again in the 1920s, but the tool had proven itself.
Payroll Taxes Began in 1937
The Social Security Act of 1935 created a new kind of federal tax that took effect in 1937. Both employers and employees began paying 1% of wages into Social Security, with the rate scheduled to climb to 3% each by 1949.13Social Security Administration. Social Security Act Today the combined Social Security and Medicare payroll tax is 15.3% of wages, split evenly between employer and employee at 7.65% each. For many working Americans, payroll taxes now take a bigger bite than income taxes.
Income Tax Reached Most Workers During World War II
For its first three decades, the modern income tax touched only a small slice of the population. In 1939, about 5% of American workers paid income tax. By 1945, roughly 60% did, as Congress cut exemptions and raised rates to fund the war.14Internal Revenue Service. The Wealth Tax of 1935 and the Victory Tax of 1942
Collecting from that many new taxpayers required a new mechanism. The Current Tax Payment Act of 1943 required employers to withhold income taxes from every paycheck and remit the money directly to the government.15United States Senate Committee on Finance. Legislative History of the Current Tax Payment Act of 1943 That pay-as-you-go structure is still how most Americans pay federal income tax.
How the Rates Got to Today
The Tax Reform Act of 1986 collapsed the rate structure to essentially two brackets, 15% and 28%, and dropped the top individual rate from 50% to 28%, the lowest since before the Great Depression.16Congress.gov. H.R.3838 – 99th Congress: Tax Reform Act of 1986 The simplicity did not last, and brackets came back.
The Tax Cuts and Jobs Act of 2017 restructured brackets again. Its individual provisions were set to expire after 2025, with rates for 2026 reverting to 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%.17Congress.gov. Expiring Provisions in the Tax Cuts and Jobs Act
Every major American tax started as a response to a specific pressure: colonial debt, civil war, world wars, an aging workforce. Each supposedly temporary measure left permanent machinery behind. The six-pence molasses duty of 1733 and the 3% Civil War income tax bear little resemblance to what a modern filer pays, but they are the same story continued.
