The federal income tax began in 1861, then stopped, then started again permanently in 1913

The United States did not always have an income tax. The first federal income tax appeared in 1861 as a temporary measure to fund the Civil War. It taxed income above $800 per year — a threshold that meant only the wealthiest Americans paid. That tax expired in 1872 after the war ended.

For the next 40 years, the federal government had no income tax. It funded itself through tariffs on imported goods and excise taxes on specific items like alcohol and tobacco. In 1894, Congress tried to bring back an income tax, but the Supreme Court ruled in Pollock v. Farmers' Loan & Trust Co. that a direct income tax on property was unconstitutional without apportionment among the states.

That changed in 1913 when the 16th Amendment was ratified, giving Congress the power to tax income directly without apportionment. That same year, the first permanent federal income tax took effect. The tax rate started at 1 percent on income above $3,000 — again, only the wealthy paid. By 1918, the top rate had climbed to 77 percent to fund World War I. Income tax has remained a permanent part of the federal system ever since.

Key Takeaways

  • The first U.S. income tax ran from 1861 to 1872 as a Civil War emergency measure and affected only the highest earners.
  • The Supreme Court struck down an 1894 income tax attempt, ruling it unconstitutional without a constitutional amendment.
  • The 16th Amendment, ratified in 1913, gave Congress permanent authority to tax income directly.
  • The modern federal income tax system began in 1913 and has continued without interruption since then.

Why the 1861 income tax was temporary

The Civil War created an when ready need for federal revenue. The government had to pay soldiers, buy weapons, and transport supplies. Tariffs alone could not raise enough money fast enough. Congress passed the first income tax in August 1861 as an emergency revenue measure.

This tax was progressive — it taxed higher incomes at higher rates — but only the top 3 percent of Americans earned enough to owe anything. Most people paid nothing. The tax included deductions for business expenses and losses, much like the system today. When the war ended in 1865, the tax remained in place for another seven years to help pay war debts, but Congress let it expire in 1872.

The failed 1894 tax and the Supreme Court's decision

After the Civil War income tax ended, the federal government relied on tariffs for most of its revenue. But tariffs raised prices for consumers and created political conflict. In 1894, during an economic depression, Congress tried again with a new income tax — this time a 2 percent tax on income above $4,000.

Wealthy taxpayers sued, arguing the tax was unconstitutional. The Supreme Court agreed in Pollock v. Farmers' Loan & Trust Co. (1895). The Court ruled that a tax on income from property — including stocks, bonds, and real estate — was a "direct tax" that had to be apportioned among states based on population. This made an income tax practically impossible to administer. The 1894 tax was struck down, and no federal income tax existed for the next 19 years.

How the 16th Amendment changed everything

The Pollock decision blocked income taxation, but it did not stop people from wanting one. Progressives and reformers argued that income tax was fairer than tariffs because it taxed wealth directly. Business leaders and wealthy individuals opposed it. The debate became a major political issue in the early 1900s.

In 1909, Congress proposed the 16th Amendment to override the Supreme Court's decision. The amendment stated: "The Congress shall have power to collect taxes on incomes, from whatever source derived, without apportionment among the several States." It took four years for enough states to ratify it, but on February 3, 1913, the 16th Amendment became part of the Constitution. That same year, Congress passed the first permanent income tax under this new authority.

The 1913 income tax and how it grew

The income tax that began in 1913 started small. The tax rate was 1 percent on income above $3,000 — roughly $95,000 in 2024 dollars. Only about 3 percent of the population owed any tax. The tax included standard deductions and allowed deductions for business expenses, charitable giving, and state and local taxes.

The tax grew quickly. When the United States entered World War I in 1917, Congress raised rates sharply to fund the war effort. By 1918, the top marginal rate reached 77 percent on the highest incomes. After the war, rates came down but remained much higher than in 1913. The income tax had become the federal government's primary source of revenue, replacing tariffs.

Why this history matters for understanding taxes today

The income tax system you file into each year is built on decisions made over 160 years ago. The 1861 tax established the idea that income could be taxed progressively — higher earners pay higher rates. The 1894 attempt and Pollock decision showed that the Constitution had to be changed to make income tax work. The 16th Amendment and 1913 tax created the permanent system that still exists.

Understanding this history explains why income tax works the way it does. The deductions for business expenses, charitable giving, and state and local taxes trace back to the 1913 design. The progressive rate structure — where higher income is taxed at higher rates — comes from 1861. The fact that Congress can change tax rates and brackets without amending the Constitution again is because the 16th Amendment gave it that power permanently.

Frequently Asked Questions

Did everyone have to pay income tax in 1861?

No. The 1861 income tax only applied to income above $800 per year, which meant only the wealthiest Americans paid. Most people earned far less and owed nothing. The tax was designed to raise money from the wealthy without burdening ordinary workers.

Why did the Supreme Court strike down the 1894 income tax?

The Court ruled that a tax on income from property — stocks, bonds, real estate — was a "direct tax" that had to be apportioned among states based on population. This made the tax unworkable. The 16th Amendment later overruled this decision by giving Congress power to tax income without apportionment.

Could Congress get rid of income tax today?

Congress could repeal the income tax through legislation, but it would need to replace that revenue with other taxes or cut spending. The 16th Amendment gives Congress the power to tax income, but it does not require Congress to use that power. Repealing income tax would require a major change in how the federal government funds itself.

Has the income tax rate always been this high?

No. The 1913 rate was only 1 percent on the highest incomes. Rates climbed during World War I and World War II, reaching 94 percent in the 1940s. Rates have changed many times since then based on economic conditions and political decisions. Today's rates are lower than they were in the mid-20th century.
