There was no income tax in US before WW1

Jul 14, 2023

Before the First World War, the United States did not have an income tax. It may seem hard to believe, but it's true. The government relied on tariffs and excise taxes to generate revenue. However, the war changed everything. The government needed more money to fund the war effort, and so the income tax was born.

The Origins of the Income Tax

The idea of an income tax was not new. In fact, it had been proposed many times before. The first income tax in the United States was enacted during the Civil War, but it was repealed after the war ended. It wasn't until the early 20th century that the idea gained traction.

The 16th Amendment

In 1913, the 16th Amendment to the Constitution was ratified, giving Congress the power to impose an income tax. The amendment states:

"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."

This amendment paved the way for the modern income tax system that we have today.

Why an Income Tax?

So, why did the government need an income tax? The answer is simple: war. The First World War was an expensive endeavor, and the government needed a way to fund it. Tariffs and excise taxes were not enough to generate the necessary revenue.

The Revenue Act of 1913

The Revenue Act of 1913 was the first piece of legislation that implemented the income tax. It established a graduated tax system, with rates ranging from 1% to 7% depending on income. The act also included a standard deduction of $3,000 for individuals and $4,000 for married couples.

The Impact of the Income Tax

The income tax has had a significant impact on the United States. It has allowed the government to fund important programs and initiatives, such as Social Security and Medicare. However, it has also been a source of controversy and debate.

The Debate Over Taxation

Some people believe that the income tax is unfair and that it places too much of a burden on the middle class. Others argue that it is necessary to ensure that everyone pays their fair share. The debate over taxation is ongoing, and it is unlikely to be resolved anytime soon.


It's hard to imagine a time when the United States did not have an income tax. However, before the First World War, the government relied on other sources of revenue to fund its operations. The income tax has had a profound impact on the country, for better or for worse. Regardless of your opinion on taxation, it is clear that the income tax is here to stay.
