Federal Taxation in America

The emergency arrived in 1861. The Civil War cost sums that tariffs could not begin to cover, and the Union government, facing a war for its survival, reached for instruments no peacetime Congress would have touched. Within two years it had enacted the first federal income tax in American history, a graduated levy that eventually rose to 10 percent on higher incomes, alongside a sprawling internal revenue system of excises on nearly everything — liquor, tobacco, manufactured goods, legal documents, professional licenses.

Brownlee treats this as a genuine rupture, not a mere spike in spending. To collect these new taxes the government created, in 1862, the office of the Commissioner of Internal Revenue — the ancestor of the modern IRS — and with it a permanent administrative apparatus reaching into the economy in ways Hamilton's excises never had. For the first time, the federal government asked citizens to disclose their incomes and taxed them progressively, on the principle that those with more should pay a larger share. That principle, once introduced, was hard to unlearn.

The Sixteenth Amendment, ratified in 1913, finally put the income tax beyond constitutional challenge, and Congress promptly enacted a modest one. At first it touched only the wealthy — a small percentage of households paid anything at all. Brownlee frames this early income tax as a deliberately class-based instrument, championed by progressives and Southern and Western Democrats who saw it as a way to shift the burden away from consumption taxes that fell hardest on the poor and toward concentrated wealth and corporate profits.

The First World War transformed it. To fund American entry, Congress raised the top rates dramatically and expanded the reach of the tax, so that by 1918 it was producing revenue on a scale that dwarfed the prewar system. Brownlee calls the settlement that emerged "soak-the-rich" taxation: highly progressive, aimed at war profits and large fortunes, and justified by the shared sacrifice of wartime. The 1920s saw Treasury Secretary Andrew Mellon roll back the top rates, but the structure survived, and the income tax was now a fixture rather than an experiment.

The most useful idea Brownlee offers is that American taxation should be read not as a rising or falling line of rates but as a sequence of distinct "tax regimes" — whole settlements about who pays, on what basis, and under what justification. Each regime, he argues, was forged in a national emergency, stabilized afterward, and then governed the country for decades until the next crisis cracked it open. The tariff regime of the nineteenth century, the progressive income-tax regime of the world wars, the mass-tax regime born of 1943: these are not just policies but political orders, each with its own coalition and its own moral story about fairness.

This reframing explains why tax reform is so hard and so rare. Regimes persist because they build constituencies — industries protected by a tariff, taxpayers accustomed to a deduction, a government dependent on a revenue stream it cannot easily replace. Changing rates is ordinary politics. Changing a regime requires a shock large enough to dislodge all of that at once, which is why the genuine turning points cluster around wars and near-catastrophes rather than election cycles.

Return to Hamilton on horseback, riding west to enforce a tax on whiskey. The scene captures the whole arc Brownlee traces: a government that wanted revenue, citizens who resisted it, and an emergency that decided the matter. Every major expansion of federal taxation followed that shape — the Civil War, the two world wars, the fiscal crises of the 1980s. None of it came from a calm decision that the country ought to tax itself more. It came from moments when the republic faced something it could not otherwise survive or win.
