The IRS—a division of the US Treasury Department that enforces the Internal Revenue Code, collects taxes, and enforces tax laws—has been a frequent victim of arson over the years.

The Internal Revenue Code is also known as Title 26 of the US Code. It was enacted in 1925 and outlines income, estate, sales, payroll, and excise tax laws.

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 For instance, in 1872, the income tax from the Civil War was repealed. But it was revived in 1894, and then repealed again in 1895.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.

The Commissioner of Internal Revenue was created in 1862 to take over federal tax collection after the President enacted a temporary income tax. That agency eventually became today's Internal Revenue Service.

From Al Capone's tax evasion to corruption and bribery within the IRS, the government agency has had its fair share of scandals. This article details many of them, outlining corruption that reveals this seemingly boring agency as anything but.

The Internal Revenue Service is led by a commissioner, who leads the IRS for a five-year term after being selected by the president of the United States. Under the commissioner, the IRS has multiple subdivisions that work on different tax groups, such as the Wage and Investment Division to handle individual wage earners.

It costs the IRS a significant amount of money to do part of its job—collecting money. For instance, the Internal Revenue Service spent $16.1B to collect $4.7T in taxes in 2023.

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.

While some people cheat on their taxes, others evade paying them altogether. This article details methods the Internal Revenue Service uses to catch these people in the act, such as scanning social media, computer data analysis, and whistleblowers.

Americans spend more than 7.9 billion hours per year doing their taxes: It's notoriously time-consuming, requiring forms, deductions, and often third-party help. But here's the twist: The IRS already has much of the data it asks you to report. Americans still have to do the work themselves partly due to big tax prep companies that lobby to keep the status quo.

The IRS arrested top mob bosses during Prohibition after the Supreme Court ruled illegally-made income could be taxed. The IRS's biggest catch was Al Capone, who was charged with tax evasion and sentenced to 11 years in prison. But Capone wasn't the only bootlegger the IRS nabbed for tax evasion during this era.

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.

The Internal Revenue Service has audited less than 1% of all individual tax returns. If you're still worried about being audited, know that some people are more likely to be audited than others, such as people who make a lot of money and those who take large charitable deductions.

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.

From July 1 to July 7, 2024, Pew Research Center conducted a survey of 9,424 adults to gauge the public's attitudes about the federal government, including government agencies and departments. Of 13 agencies, 10 had net favorable ratings of 15 percentage points or more. Topping the list were the National Park Service (76% favorable), the US Postal Service (72%) and NASA (67%).

In 2025, about half of Americans were able to file taxes directly with the IRS for free. It was the second year of the agency's new program, which cuts out intermediaries. Though tax preparation has been free for many Americans, critics say tax companies upsell customers.

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.

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

Death taxes date back to 700 BCE and were used in Ancient Rome and Ancient Egypt. In the US, they've been used to finance wars since the Civil War, and have been levied on both the estate and beneficiary. The estate tax created during WWI to help finance war efforts is still in effect today.

The Roth IRA is one of the most popular retirement accounts in the US. Nearly a quarter of Americans contributed to a Roth IRA in 2023. But this type of financial account hasn’t been around for that long.

For many, filing taxes can be complicated and overwhelming. Some argue that the tax system obscures certain aspects of the US tax code, making it difficult for taxpayers to accurately assess potential reforms.

Ratified in 1913, the 16th Amendment paved the way for a far-reaching federal income tax and supercharged the country’s coffers. Before then, the US depended on import tariffs and so-called consumption taxes to raise revenue.

About 50 percent of federal revenue comes from individual income taxes, 7 percent from corporate income taxes, and another 36 percent from payroll taxes that fund social insurance programs. See breakdown in charts here.

Corporate taxes, which make up roughly a third of the federal government's revenue, have been calculated using a flat 21% rate since the Tax Cuts & Jobs Act of 2017. The current rate is considered low both by historic standards (it averaged over 50% in the 1950s and 1960s) and compared to other countries.

That adds up to close to $1T in what's known as the "tax gap." Read a breakdown on the main drivers of tax evasion (distinct from legal tax avoidance) in the US.

As Treasury secretary, Alexander Hamilton designed an excise tax on whiskey that provoked violent resistance in western Pennsylvania. The Whiskey Rebellion ended when George Washington mobilized state militias under federal authority to enforce the law.

The Roth IRA was established by Senator William Roth in 1997 as part of the Taxpayer Relief Act. Roth IRAs differ from traditional IRAs in that they allow individuals to invest after-tax income for retirement rather than pre-tax income.

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.

In the early 1900s, 30% to 40% of government tax revenue came from liquor, wine, and beer, a reliance that made Prohibition seem like a fiscal impossibility. But the passage of the federal income tax in 1913 changed the calculus, which helped allow the government to ban alcohol production and sales.

Most Americans across the country have one thing in common: They hate doing their taxes. Many use an accountant or an online service like TurboTax to avoid doing taxes themselves. In this video, two journalists decide to do their taxes on their own for the first time.

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.

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.

An IRA lets individuals at most income levels invest either pre- or post-tax money for retirement. IRAs are often good solutions for people who don’t have the option to invest in a 401(k) plan—or for those who want to put even more money aside for retirement.

While America’s federal government primarily raises revenue through personal and corporate income taxes, it's a different story for each of the 50 states. This map shows how every state raises tax revenue for government activities.
