The nation had few taxes in its early history. From 1791 to 1802, the United States government was supported by internal taxes on distilled spirits, carriages, refined sugar, tobacco and snuff, property sold at auction, corporate bonds, and slaves. The high cost of the War of 1812 brought about the nation’s first sales taxes on gold, silverware, jewelry, and watches. In 1817, however, Congress did away with all internal taxes, relying on tariffs on imported goods to provide sufficient funds for running the government.
In 1862, in order to support the Civil War effort, Congress enacted the nation’s first income tax law. It was a forerunner of our modern income tax in that it was based on the principles of graduated, or progressive, taxation and of withholding income at the source. During the Civil War, a person earning from $600 to $10,000 per year paid tax at the rate of 3%. Those with incomes of more than $10,000 paid taxes at a higher rate. Additional sales and excise taxes were added, and an “inheritance” tax also made its debut. In 1866, internal revenue collections reached their highest point in the nation’s 90-year history more than $310 million, an amount not reached again until 1911.
The Act of 1862 established the office of Commissioner of Internal Revenue. The Commissioner was given the power to assess, levy, and collect taxes, and the right to enforce the tax laws through seizure of property and income and through prosecution. The powers and authority remain very much the same today.
In 1868, Congress again focused its taxation efforts on tobacco and distilled spirits and eliminated the income tax in 1872. It had a short-lived revival in 1894 and 1895. In the latter year, the U.S. Supreme Court decided that the income tax was unconstitutional because it was not apportioned among the states in conformity with the Constitution.
In 1913, the 16th Amendment to the Constitution made the income tax a permanent fixture in the U.S. tax system. The amendment gave Congress legal authority to tax income and resulted in a revenue law that taxed incomes of both individuals and corporations. In fiscal year 1918, annual internal revenue collections for the first time passed the billion-dollar mark, rising to $5.4 billion by 1920. With the advent of World War II, employment increased, as did tax collections-to $7.3 billion. The withholding tax on wages was introduced in 1943 and was instrumental in increasing the number of taxpayers to 60 million and tax collections to $43 billion by 1945.
Enrolled agents were established after the Civil Wars to fairly present damage claims from property seized during the War. After the 16th amendment was passed, their influence was extended to include claims for US citizens against income tax issues and taxpayer representation, culminating in Circular 230 during WW II. In contrast to attorneys and CPAs that are state-licensed, enrolled agents are federally licensed and obtain their license through either testing or IRS enrollment. They remain the only tax professionals in America licensed by the Federal government and required by law to take annual, federal income-tax specific continuing education.
