Background and History of the IRS

The Internal Revenue Service (IRS) was established in 1862 during the Civil War to finance the war effort through income tax collection. Prior to the IRS’s creation, the U.S. government relied primarily on tariffs and excise taxes for revenue. The agency’s authority significantly expanded following the ratification of the 16th Amendment in 1913, which authorized a permanent federal income tax.

Today, the IRS manages a complex tax system affecting nearly all Americans. It oversees the collection of federal income taxes, administers various tax credits and deductions, and enforces compliance through audits and investigations.

How the IRS Works

Each year, millions of taxpayers submit their tax returns using forms like the Form 1040, reporting their income, deductions, and credits. The IRS processes these filings, verifying information accuracy through automated checks and manual reviews. Based on this processing, the IRS calculates whether taxpayers owe additional amounts or are eligible for refunds.

If taxes owed are not paid by the due date (usually April 15, with some exceptions), the IRS can assess penalties and interest. In cases of nonpayment, the agency has authority to collect owed taxes through garnishments, liens, or asset seizures.

The IRS also offers assistance programs, including:

  • Payment plans for taxpayers unable to pay in full
  • Tax credits like the Earned Income Tax Credit (EITC)
  • Taxpayer education, forms, and guidance accessible via IRS.gov

Who Does the IRS Affect?

The IRS impacts virtually all individuals and businesses earning income in the United States—from employees and freelancers to corporations and retirees. Compliance with IRS regulations is mandatory, and interactions range from annual filing to responding to audits or notification letters.

Common Misconceptions About the IRS

  • The IRS is a tax collection agency, not an enforcement agency aimed at punishment.
  • Owing taxes does not mean immediate arrest, but ignoring tax obligations can result in serious legal and financial consequences.
  • The IRS only communicates through official channels; beware of scams pretending to be IRS agents.

Practical Tips for Working with the IRS

  • File returns accurately and on time to avoid penalties.
  • Maintain organized financial records to support your filings.
  • Use official IRS resources at IRS.gov for reliable information.
  • Contact the IRS promptly if you face payment difficulties to explore options like installment agreements.
