America at 250: How Taxes Have Evolved Since the Revolution

Think tax season is bad now? At one point, America's top income tax rate hit 94%. Before that, there was no permanent federal income tax at all.

Over the past 250 years, the government has repeatedly changed how it taxes income in response to wars, economic pressures and shifting priorities. As America celebrates its 250th birthday, here's how the federal income tax became the system taxpayers know today.

For the first half of the country's history, the federal government funded itself without a permanent income tax.

“The Republic operated without one for 124 years,” said Chad Cummings, certified public accountant (CPA) and founder of Cummings & Cummings Law.

Instead, the government relied on other sources of revenue, including tariffs and excise taxes. 

According to Christopher Stroup, a certified financial planner (CFP) and founder of Silicon Beach Financial, early income taxes were generally tied to specific needs, such as funding wars, rather than serving as a permanent source of revenue.

Stroup said, “Early versions were temporary and aimed primarily at funding war efforts or taxing the highest earners, not the average American household."

When the federal income tax became permanent in 1913, it wasn’t intended to affect most Americans.

“The 1913 ratification of the 16th Amendment began with a top rate of 7% on income above $500,000, roughly $15.8 million in today's dollars,” Cummings said.

“Congress sold it as a tax on the ultra wealthy. Within four years, World War I pushed the top rate to 77%, and the base expanded to cover ordinary workers -- and the rest is history.”

The federal income tax continued to expand in the decades after World War I. By 1944, the top marginal tax rate had climbed to 94%, one of the highest levels in U.S. history. But that figure doesn’t tell the whole story.

“The historical 90%-plus top marginal rate applied to taxable income above $200,000 during the Eisenhower era, but almost nobody paid it,” Cummings said.

He explained that the tax code included numerous deductions, shelters and exclusions that reduced what many high earners actually paid. As a result, effective tax rates were often far lower than the headline rates that appeared in the tax code.

Cummings added, “Marginal rates get all the press coverage, but the effective rate is what counts at the end of the day after deductions and tax planning." 

Despite its “humble beginnings,” the federal income tax gradually became a much larger part of American life.

“The income tax was introduced as a means to just tax wealthy people,” said Wayne Winegarden, economist at the Pacific Research Institute. “Now, with the expansion of the size and scope of the government, there is an expansion of who the income tax system is applied to.”

Winegarden said income taxes are still concentrated among higher earners. However, he said today's taxpayers face a much more complex system than earlier generations.

“So, in a way, the more things change, the more they stay the same.” 

Throughout America’s history, the federal income tax changed because lawmakers adapted the system to accommodate evolving political and economic realities. However, the tax code hasn’t always kept up with those changes. 

For example, Cummings said the tax code hasn’t been fully rewritten since 1986 and is struggling to keep pace with new ways of working and earning income, such as the rise of the gig economy, digital nomads and e-commerce.

“(Artificial intelligence) will probably be the catalyst that forces a rewrite of the (tax) code as we start to think about the great displacement of workers by automation and topics like UBI (universal basic income) enter the conversation,” Cummings said. 

The biggest lesson from 250 years of tax history may be that today's tax rules are not permanent.

Tax brackets, deductions, credits and filing requirements often feel fixed. But the federal income tax has been rewritten, expanded and reimagined repeatedly as the country changed.

For taxpayers, that means paying attention to more than just this year's refund or tax bill. The next major shift may not come from Washington alone. It could come from new technologies, new ways of working and new sources of income that lawmakers eventually decide need a place in the tax code.
