For nearly a century and a half, the government of the United States was funded by a single source of revenue. Not income tax, not payroll tax, not corporate tax, none of which existed in any meaningful form. Instead, the Treasury in Washington depended on customs duties: taxes paid at American ports on crates, barrels, and bolts of cloth arriving on foreign ships. From 1789, the year the Constitution took effect, through the eve of the First World War, tariffs provided roughly 80 to 95 percent of all federal revenue.

They paid for the navy, the army, the postal service, the courts, the diplomats, the lighthouses, westward expansion, even the pensions of Civil War widows. On the surface, the arrangement looked remarkable. The money for American government seemed to arrive from elsewhere, carried in by foreigners and extracted from them. It was the political fantasy of a tax that never touches the taxpayer.

In practice, it worked very differently. The tariff was collected at the border, but it was paid by the people living inside it. Americans financed their federal government through every imported yard of wool on their backs, every pound of sugar in their cupboards, every nail driven into a barn. The tax was invisible because it was baked into the price of goods, and figuring out who actually carried that burden, which region, which class, which industry, became the central political fight of the nineteenth century.

The issue triggered a near civil war in 1832, contributed to the actual Civil War in 1861, built the Gilded Age fortunes that still bear famous names, and collapsed in 1913, replacing the entire architecture of federal finance. When the new republic began, it was catastrophically broke. The Revolutionary War had been financed on borrowed money, worthless paper currency, and the patience of creditors. The government under the Articles of Confederation could not force the states to pay their share of the national debt.

By the time George Washington took office, the debt stood at over $75 million. The country owed France, Dutch bankers, Spanish lenders, its own unpaid soldiers, and American merchants who had supplied the army on credit. The very first substantive law passed by the first Congress, the Tariff Act, was signed by President Washington on July 4, 1789. Sponsored by James Madison, the act placed a flat 5 percent duty on most imported goods, with higher rates on items domestic producers wanted protected.

Its stated purposes were the support of government, the discharge of the national debt, and the encouragement and protection of American manufacturers. Those three bundled goals would quietly tear the country apart over the next seventy years. Alexander Hamilton, the first Treasury Secretary, saw the tariff as more than a revenue tool. In his 1791 Report on Manufactures, he argued that the young nation needed its own factories, mills, and foundries, a manufacturing base independent of Britain and Europe.

The way to build it was to shield American infant industries from cheaper foreign products by taxing imports heavily enough to level the playing field. Thomas Jefferson initially disagreed, believing the country’s future lay in independent farming, but even he eventually came around. The War of 1812, which cut off British trade and forced Americans to produce their own goods, proved domestic manufacturing was both possible and strategically necessary. After the war, British manufacturers tried to crush the new American factories by dumping cheap goods on the market.

In response, Congress passed the Tariff of 1816, raising average duties to around 20 percent with the explicit aim of protecting American producers. At that moment, the tariff changed character. It was no longer simply a revenue measure. It was industrial policy, with the federal government picking winners and losers inside the economy.

New England textile mills and Pennsylvania iron forges were winners. Southern planters were not. The South depended on exporting cotton, tobacco, rice, and other raw materials, mostly to Britain, and importing finished manufactured goods. When Congress raised tariffs, the South was hit twice.

Nearly everything Southerners bought became more expensive because imported goods carried the new tax, and because foreign countries sold less to America, they had less American money to buy Southern cotton. Southern exports suffered, Southern purchasing power shrank, and Northern manufacturers grew rich under the shelter of the tariff wall. The arrangement had the symmetry of a trap: the South paid and the North collected. Nothing illustrated this more sharply than the Tariff of 1828, which raised average duties on dutiable imports to around 62 percent, applied to roughly 92 percent of all goods entering the country.

Southerners named it the Tariff of Abominations. In the House, only four Southern votes were cast in favor; sixty-four were cast against. John C. Calhoun of South Carolina, vice president under both John Quincy Adams and Andrew Jackson, anonymously wrote the South Carolina Exposition and Protest, arguing that the tariff was unconstitutional and that individual states possessed the sovereign right to nullify federal laws they judged beyond constitutional limits.

The doctrine of nullification was explosive, implying the United States was not a single nation but a loose confederation of independent sovereigns. For four years, the question simmered. In 1832, Congress passed a mildly revised tariff that failed to satisfy Southerners, and South Carolina formally adopted its ordinance of nullification, declaring both the 1828 and 1832 tariffs unenforceable within its borders and threatening secession if the federal government attempted to collect them by force. President Andrew Jackson, himself a Southerner and a slave owner, did not blink.

He issued a proclamation declaring nullification treason, and Congress passed the Force Bill in early 1833, authorizing him to use the army. For weeks, it looked like civil war might arrive thirty years early, triggered not by slavery but by taxes on imported wool. Henry Clay negotiated a compromise tariff that gradually lowered rates, and South Carolina backed down. But the fuse had been lit.

Jackson privately admitted the real issue was never the tariff itself but a widening gap between the industrial economy of the North and the agricultural, slave-based economy of the South. The next time that gap exploded, it would not be contained. By the late 1850s, tariff rates had actually calmed. The Walker Tariff of 1846 and the Tariff of 1857 had lowered average duties to around 20 percent, the lowest in decades.

But in the North, a coalition was building that wanted them raised again. Pennsylvania iron manufacturers, New England textile mills, Midwestern railroad companies, and the emerging Republican Party all shared one conviction: the American industrial future required protective duties. In 1860, Justin Morrill, a Republican congressman from Vermont, drafted a dramatically higher tariff. The bill passed the House in May 1860, before Abraham Lincoln was even elected.

Southern senators had enough votes to block it through most of that year. Then came November. Lincoln won the presidency. South Carolina seceded in December, and by February six more Southern states had followed.

When their senators left Washington for the Confederacy, they took their blocking votes with them. The Morrill Tariff sailed through the Senate on February 20, 1861, and was signed by outgoing President James Buchanan on March 2, two days before Lincoln’s inauguration. It roughly doubled the average tariff rate. Congress passed two more Morrill-sponsored hikes during the war, pushing rates to levels not seen since the Tariff of Abominations.

Whether the tariff caused the Civil War has been debated for over a century and a half. It did not by itself. The Confederacy left the Union over slavery, and its secession documents say so explicitly. But the tariff was never far from the fight.

It was one of the economic grievances layered on top of the slavery dispute. When Lincoln was asked why he would not simply let the South go in peace, he reportedly replied, if I do that, what would become of my revenue? What then would become of my tariff? The federal government depended on customs duties for nearly all its income, and most of those duties were collected at Southern ports.

Letting the Confederacy walk away meant letting the money walk away. The war also forced a temporary experiment. In 1861, Congress passed the Revenue Act, including the first federal income tax, a 3 percent levy on incomes above $800. It was a desperate wartime stopgap.

In 1872, with the war over and tariff revenue flowing, Congress repealed it entirely. For the next forty years, the United States returned to funding its central government almost exclusively through import duties. But the memory of that wartime tax never fully faded. The Gilded Age that followed produced enormous wealth at the top and crushing hardship below.

By 1890, roughly 11 million of the country’s 12 million families earned less than $1,200 a year, with the average income among that group near $380. Meanwhile, industrialists like Andrew Carnegie, John D. Rockefeller, J. P.

Morgan, and Jay Gould accumulated fortunes beyond anything the country had ever seen. They were known as the robber barons, and many were enormous beneficiaries of the tariff system. In 1890, Representative William McKinley of Ohio, later president and later assassinated, pushed through the McKinley Tariff, raising average rates to about 48 percent. After McKinley became president in 1897, Congress passed the Dingley Tariff, still higher.

Between 1897 and 1907, the cost of living in the United States rose by nearly 25 percent. Groceries, clothing, furniture, tools, everything a working family needed got more expensive, while the protected steel mills and textile factories posted record profits. Their owners built mansions along Fifth Avenue and Newport, donated libraries, collected European art, and sent their daughters to be presented at the British Court. The central economic question was who actually paid.

Legally, the tariff was paid by the importer of record, the American merchant who brought foreign goods through customs. Economically, that was only the beginning. The burden was distributed among foreign exporters, who might lower prices to keep selling into the American market, American importers, who might absorb some cost in reduced margins, and American consumers, who ultimately paid higher prices when importers passed the tax along. In almost every case studied, consumers paid the largest share.

A tariff was, in practical operation, a sales tax on imported goods, and sales taxes are paid by the people who buy things. In the Gilded Age, that meant a Kansas farmer paid it on his plow, a Chicago seamstress on her thread, a West Virginia miner on his boots, a Nebraska railroad worker on his winter coat. The system functioned as a regressive wealth transfer from working families and farmers to wealthy manufacturers. One critic described tariffs as a tax on the shoes of the laborer to protect the profits of the shoemaker who hired him.

Farmers understood this. The Grange, the Farmers’ Alliance, the Populist Party, and the Progressives all raged against the tariff system. Farmers sold their wheat, corn, and cotton into unprotected world markets at whatever global prices offered, while buying their tools and clothing inside a protected American market where prices were artificially inflated. The farmer was squeezed on both ends, and the squeeze financed mansions in Manhattan.

By the early 1900s, the pressure for change had become overwhelming. Progressive reformers argued there had to be a fairer way to fund the government, one that taxed people according to their ability to pay. In 1909, Congress proposed a constitutional amendment permitting a federal income tax. An earlier income tax passed in 1894 had been struck down by the Supreme Court the following year.

A constitutional amendment was the only way around that decision. What happened next was one of the strangest ironies in American politics. Conservative Republicans led by Senator Nelson Aldrich of Rhode Island supported sending the amendment to the states because they expected it to fail. They thought the gesture would relieve political pressure on the tariff without changing anything.

They were catastrophically wrong. State legislatures ratified one after another, and on February 25, 1913, the Sixteenth Amendment was certified. The federal government now had explicit power to tax incomes. The same year, the Underwood-Simmons Tariff Act slashed average rates for the first time in half a century and enacted the first permanent income tax under the new amendment.

At first, it applied only to the very wealthy. In 1913, only about one in 271 Americans paid any income tax at all, with a top rate of 7 percent. Then World War I required revenue on an unprecedented scale. Rates were raised, the threshold lowered, and by the end of the war the income tax had become a major source of federal income.

By World War II, extended to nearly every working American, it had become the dominant pillar of federal finance that it remains today. Tariffs, which had provided roughly 90 percent of federal revenue in the 1800s, would provide less than 5 percent for most of the twentieth century. The tariff system did not go quietly. It made one final, catastrophic appearance.

In the late 1920s, agricultural prices were collapsing and President Herbert Hoover had campaigned on a promise to raise tariffs to help farmers. After the stock market crashed in October 1929 and the economy slid into the Great Depression, Congress doubled down. Senators Reed Smoot of Utah and Representative Willis Hawley of Oregon shepherded through the Tariff Act of 1930, raising average duties on dutiable imports by roughly 20 percent, to levels second only to the Tariff of Abominations. Over a thousand American economists petitioned Hoover to veto the bill.

J. P. Morgan’s Thomas Lamont later said he almost went down on his knees to beg Hoover to veto it. Hoover signed it on June 17, 1930.

The response from the rest of the world was swift. Canada retaliated immediately. European nations followed. A global trade war erupted precisely when the global economy could least afford one.

Between 1929 and 1934, world trade collapsed by roughly two-thirds. American exports and imports fell by about 67 percent. Unemployment climbed from around 8 percent to 25 percent. Smoot-Hawley did not cause the Depression, but virtually every mainstream economist and historian agrees it made it deeper, longer, and more global.

In 1932, voters threw Hoover out of office. Smoot and Hawley lost their seats as well. Franklin Roosevelt took office in 1933, and Secretary of State Cordell Hull pushed through the Reciprocal Trade Agreements Act of 1934, fundamentally shifting American trade policy toward negotiated tariff reductions. After World War II, the General Agreement on Tariffs and Trade, later the World Trade Organization, institutionalized the global movement toward lower tariffs.

American average tariff rates settled at around 5 percent and stayed there for roughly seventy years. Then the tariff debate returned. Modern tariffs began during the first Trump administration in 2017 and 2018, and research from the University of Chicago’s Becker Friedman Institute found American consumer prices on affected goods rose almost immediately. Washing machines went up by nearly 12 percent.

But the real revival came in 2025, when a second Trump administration launched the most sweeping protectionist program in nearly a century. By September of that year, the trade-weighted statutory tariff rate had climbed to roughly 27 percent, the highest in nearly a century, exceeded only by the Smoot-Hawley years. The Yale Budget Lab calculated the new tariffs would raise consumer prices by between 1. 7 and 2.

9 percent in the short run, costing the average household between $2,800 and $3,800 per year. The Peterson Institute for International Economics concluded that American importers and consumers were bearing roughly 96 percent of the cost, with foreign exporters absorbing only about 4 percent. The New York Federal Reserve reached a similar conclusion. Federal Reserve Chair Jerome Powell attributed essentially all of 2025’s overshoot above the 2 percent inflation target to tariffs.

In February 2026, the Supreme Court ruled 6 to 3 that the administration’s use of emergency powers to impose the broadest set of these tariffs had never been authorized by Congress. By then, the inflationary damage had largely been done. The deepest irony threads together everything from Hamilton to McKinley to Smoot-Hawley to the present. The romantic nostalgia for an America funded by tariffs rests on a historical misunderstanding.

Tariffs funded the nineteenth-century federal government only because that government was tiny. Federal spending in the 1800s amounted to only 2 to 4 percent of GDP. In 2024, it was around 25 percent. The federal government today is roughly ten times larger as a share of the economy than it was in the heyday of the tariff state.

No realistic tariff rate could finance a modern American government. To try would require rates so high that trade would collapse, revenue would disappear, and the economy would crater, which is precisely what Smoot-Hawley demonstrated. So who actually paid for America’s tariff-funded government all those years? The same answer that applies today.

Americans paid, specifically the Americans who consumed the most relative to their income: farmers, workers, immigrants, families scraping by on narrow margins. The tariff was a tax that hid inside the price of goods, letting politicians pretend the government was being financed by foreigners while the actual money came out of American wallets. It built the early republic, paid for the Louisiana Purchase and the Mexican War, and funded the Union armies that saved the United States as a political entity. It also enriched a small industrial elite at the expense of a vast consuming public and played a role in nearly every major sectional crisis of the century.

The nineteenth-century tariff system did not fall because Americans suddenly loved the income tax. It fell because enough Americans, over enough decades, slowly came to understand what was being taken from them, how, and by whom. The Sixteenth Amendment did not eliminate the burden of government. It simply moved the burden out of the shadows into daylight, where it could be argued about openly.

The choice between a visible tax and a hidden one is not a choice between paying and not paying. It is a choice between knowing what you are paying for and being falsely told that someone else is paying for it.
