As April 15th looms, many of us start to scramble. You know the day: Tax Day—the deadline to prove to the IRS that you paid the right amount of income tax, claim a refund if you overpaid, or begrudgingly send what you still owe. 

Before America went digital, it was common for American taxpayers to rush to a post office just before the 11:59 p.m. deadline on April 15th to get their tax returns postmarked and on their way to the IRS. Now, digital returns are more popular than ever. While this process is arguably more convenient, getting income tax forms filled out and filed correctly remains a stressor for many American taxpayers. 

Why do Americans go through this ordeal every year, and how did it begin in the first place? Let’s take a brief look at the history of income tax in the U.S. now. 

Timeline of Federal Income Tax History in the United States 

Our country’s approach to income tax and the tax code has changed many times over the years. This timeline highlights some of the major milestones: 

visual summary of how the U.S. Federal Income Tax System Evolved over time.
  • 1861: Congress passes a revenue act placing a tax on personal income to help cover the costs of the Civil War. 
  • 1871: Congress repeals the Revenue Act of 1861. 
  • 1894: Congress passes a flat-rate federal income tax that just one year later is ruled unconstitutional by the U.S. Supreme Court. 
  • 1909: With the passage of the Sixteenth Amendment to the U.S. Constitution, Congress grants itself the authority to impose an income tax on citizens without regard to their state’s population, overcoming the crux of the Supreme Court’s previous 1895 ruling.  
  • 1913: The Sixteenth Amendment is ratified. Congress sets an income tax filing deadline of March 1st. 
  • 1914: Form 1040 is introduced by the Treasury Department. 
  • 1918: Congress changes the income tax deadline to March 15th. 
  • 1953: The Internal Revenue Service, a reorganization of the long-standing Bureau of Internal Revenue, is established. 
  • 1998: The IRS significantly updates and restructures itself following the passage of the IRS Restructuring and Reform Act of 1998, a law that for the first time creates an independent taxpayer advocacy organization within the agency. 
  • 2017: President Donald Trump signs a $1.5 trillion tax reform bill, the largest adjustment to the tax system in decades. Among the changes were a 14% reduction in the corporate tax rate and the elimination of the personal exemption and expansion of the child tax credit from Form 1040 (for individuals and married couples). 

Why Was the U.S. Income Tax Created? 

The U.S. income tax system was born out of necessity. In 1861, during the Civil War, Congress passed the Revenue Act to generate funds for the Union war effort, marking the first time Americans were taxed directly on their income. Though this early tax was temporary, it laid the groundwork for future legislation. 

How Has Tax Filing Has Changed Over the Years? 

Tax filing has shifted from a manual, paper-based process to a fast, mostly digital experience. In the early days of income tax, taxpayers filled out paper forms like the now-famous Form 1040 by hand and mailed them to the IRS. Over time, filing requirements and deadlines evolved, with Tax Day eventually landing on April 15. 

The rise of digital technology marked a major turning point. Today, , making the process faster and more accessible. E-filing software, digital W-2s, and online tax tools have simplified what was once a paper-heavy and time-consuming task. 

Who Needs to Pay Federal Income Taxes Today? 

Today, most working Americans are required to file a federal income tax return if they earn above a certain threshold, which varies depending on factors like: 

  • Age 
  • Filing status 
  • Income type 

Currently single filers under age 65 must file if they earn more than $13,850. Self-employed individuals need to file if they earn over $400. Taxable income can include: 

  • Wages 
  • Freelance earnings 
  • Investment returns 

Because tax law is complex and ever-changing, many individuals and businesses turn to accountants to ensure compliance, maximize deductions, and reduce the risk of costly errors, making the role of accounting professionals more important than ever.
