Individual income taxes are the federal government's primary revenue source, see a tracker that breaks down where the rest of the budget comes from

The US government historically makes nearly half of its total revenue last year from individual income taxes. But the US makes also makes money from a variety of other sources, including Medicare taxes and corporate income taxes. However, the federal government has run a deficit since 2001—reaching a peak of $3.13T in 2020.

Learn how the US tax code works and why it's important

First published in 1926, the US Code is the official codification of federal statutes in the US. Title 26 of the US Code, for instance, lists all of the federal tax laws of the United States. A new edition is published every six years.

80% of Americans are bothered that some wealthy people don't pay their fair share of taxes

That's according to data from Pew Research Center. While most people are primarily taxed on their wages, many people in America's 1% derive much of their income from investments instead, which are often taxed at preferential capital gains rates. This structure was shaped by a series of legislative cuts that began in earnest with the 1978 Revenue Act and the 1981 Economic Recovery Tax Act.

Capital gains taxes were first levied in the US in 1913

However, up until 1921, they were treated the same as ordinary income. Ever since then, rates have swung up and down.

Why the rich don't pay taxes like you do

The system behind the US income tax isn't as straightforward as it looks. You earn money. Taxes get taken out. Case closed … right? Not exactly. In this episode of "1440 Explores," we break down how the US tax system actually works, from confusing deductions and misunderstood tax brackets to why the wealthiest Americans often end up paying a very different tax than everyone else.

What America's 1% pays in taxes, by state

In the US, the top 1% of earners contribute 45% of all personal income taxes collected nationwide. But not all states are created equal when it comes to income tax. Some states are more dependent on the 1% than others for tax revenue. SmartAsset recently examined IRS tax return data to determine exactly how much the top 1% of earners in each state paid in taxes.

See comparisons of different countries' taxation strategies

Taxes are a major revenue source for most countries, and how each government taxes citizens often reflects the country's economy. Developed countries tax at much higher rates than developing ones, and as a country grows its GDP, it also typically grows the proportional percentage of taxes it gains from its citizens.

The US officially adopted an income tax in 1913

The US first levied income taxes during the Civil War, but modern income taxes became an American fixture in 1913. Two years earlier, Congress passed the 16th Amendment to give the government the right to tax individuals' and businesses' income. The US still technically levies the same federal income tax now as it did then—though it's evolved.

The .1% of Americans once controlled 7% of all US wealth. Today, they control closer to 18%.

Warren Buffett paid a lower effective tax rate than his secretary

While wages and salaries are taxed progressively at rates up to 37%, long-term investments are taxed at lower rates: 0%, 15%, or 20%. For wealthy individuals like Buffett, whose income mainly comes from investments, this means paying a lower effective tax rate than someone earning a salary.

Historically, only about 1% to 2% of Americans had to pay the federal estate tax

Recent IRS data shows that between 2011-16, that number dropped even lower: The federal estate tax only impacts about 0.2% of Americans. Death taxes typically only impact the rich, and the federal estate tax is no exception.

Some policymakers take issue with long-term capital gains being taxed at a preferential rate compared to income from paid work

The concept of taxing unrealized capital gains—when an asset’s value increases but has yet to be sold—has been increasingly debated. Other policymakers in recent years have supported lowering the highest long-term capital gains tax rate and are generally opposed to levying taxes on unrealized capital gains.

Most Americans take the standard tax deduction

A tax deductible is an expense that a taxpayer or business can subtract from adjusted gross income, reducing their taxable income and therefore reducing the amount of taxes owed. Governments often use tax deductibles as a way to reward people who do things that are considered beneficial to society, like charitable donations.

On July 1, 1862, the agency now known as the Internal Revenue Service was established and named the Bureau of Internal Revenue

It was created to collect the first-ever US income tax, which was created to help pay for the Civil War. After gaining their independence from Britain, Americans were skeptical about giving the federal government absolute power to collect federal income taxes. As a result, early US tax laws dictated that direct taxes, like income taxes, had to be directly apportioned to a state's population. The nation went back and forth on its federal tax laws multiple times. For instance, in 1872, the income tax from the Civil War was repealed. But it was revived in 1894, and then repealed again in 1895. In 1913, Congress passed the 16th Amendment, giving Congress the power to levy income taxes on individuals and corporations without apportioning the burden among the states in line with population, once and for all.

Before the 16th Amendment, US tax law required direct taxes to be directly apportioned to a state's population

Due to these requirements, the federal government could not impose many direct taxes. Direct taxes include property and income taxes, whereas indirect taxes include duties and excises.

Why do long-term capital gains get taxed at preferential rates?

The 1920s defined capital gains as “unearned” taxable income—as opposed to “earned” income from jobs—and set into practice preferential tax rates for long-term capital gains that are hotly debated to this day. This historical review explores how voices in favor of preferential rates were arguing on behalf of greater market liquidity and incentive for investment activity. Learn more about the real history of capital gains tax rates here.

Short-term capital gains are gains on sales made in less than a year

In 2024, a single filer making anywhere between $200,001 and $243,725 per year would pay a 15% tax on long-term capital gains. But when it comes to short-term capital gains, they’d be taxed at the same rate as their regular income, which, in their case, is 32%.
