In 2022, the IRS took 14.6 cents of every dollar of personal income — the highest bite in over two decades. Two years later, that rate dropped to 12.0 cents. What happened? And why does a resident of D.C. hand over more than twice the share of someone in Alaska?
The American tax rate keeps a secret. For all the fury generated by every election-year tax fight — Kennedy’s cuts, Reagan’s revolution, Clinton’s increases, Bush’s relief, Trump’s TCJA — the effective rate has bounced inside a surprisingly narrow band for 76 years. In 2024, Americans paid 12.0% of personal income in taxes. In 1970, the number was 12.0%. Same rate, half a century apart.
But “narrow band” does not mean “boring.” That rate spiked to 14.3% at the peak of the dot-com boom, cratered to 9.5% during the Great Recession, then surged to a modern high of 14.6% in 2022 as investors locked in capital gains. Two years later it reverted to 12.0%, as if nothing happened. The national numbers move with the economy far more than with Congress.
But here’s where it gets interesting. The state map tells a completely different story — one where geography matters more than legislation.
The stacked view reveals something that the total-rate line disguises: the federal rate swings wildly, but state/local taxes have been a slow, steady escalator.
In 1948, state and local governments took just half a penny of every dollar — 0.5% of personal income. By 2024 that share had climbed to 2.3%, a 4.6-fold increase. This was driven by the postwar spread of state income taxes: before the war, most states relied on property and sales taxes. By the 1990s, 43 states had adopted broad-based income taxes, and the state/local share plateaued around 2.3–2.9%.
The federal side is where the drama lives. Federal taxes peaked at 11.8% in 2022 — fueled by a tidal wave of capital gains realizations as investors sold into a falling market — then snapped back to 9.6% by 2024. That 2.2-percentage-point swing in two years dwarfs anything Congress has achieved with legislation over the same period.
The Clinton-era peak (2000). The dot-com boom pushed the effective rate to 14.3% as capital gains flooded the Treasury. When the bubble popped and the Bush tax cuts took effect, the rate plunged to 11.5% by 2002 — nearly three points in two years.
The Great Recession trough (2009). The rate hit a modern low of 9.5%. Not because anyone cut taxes — incomes collapsed, capital gains vanished, and the progressive structure meant less income in the higher brackets.
The 2022 anomaly. Investors who had accumulated years of unrealized gains during the bull market sold into declining prices, crystallizing taxable gains on the way down. California, New York, and Massachusetts — where concentrated wealth drives outsized capital gains — saw their effective rates jump 2–3 percentage points in a single year. By 2024, the entire surge had unwound.
The gap between the top and bottom is staggering. A resident of Washington, D.C. surrenders 16.9% of personal income to tax collectors — federal, city, and local combined. An Alaskan? Just 7.9%. That 9-percentage-point gap means a D.C. household earning $100,000 pays nearly $9,000 more in taxes than the identical household in Anchorage.
But the reason isn’t just state tax policy. Two forces stack on top of each other. First, progressive federal taxation: high-income states like Connecticut, Massachusetts, and D.C. have residents concentrated in higher federal brackets, so they pay a higher effective federal rate per dollar of income. Second, those same wealthy states tend to layer on their own income taxes at 4–5% of personal income.
The result is a double penalty for living in a high-income, high-tax state — and a double discount for low-income states without income taxes. Mississippi’s 8.1% rate reflects both low state taxes and low incomes pushing residents into lower federal brackets.
Nine states levy no broad-based income tax: Florida, Texas, Washington, Tennessee, Wyoming, Nevada, South Dakota, Alaska, and New Hampshire. Political campaigns love to tout this as a huge advantage. But the data tells a more nuanced story.
| State | Federal | State + Local | Total Rate | Income Tax? |
|---|---|---|---|---|
| No Income Tax States | ||||
| Florida | 12.0% | 0.1% | 12.1% | No |

Florida’s total rate is 12.1% — almost exactly the national average. That’s because Florida has high incomes (lots of retirees with investment income pushing them into higher federal brackets), and the federal government doesn’t care whether you live in a no-tax state. Federal taxes alone eat 12 cents of every dollar Florida earns.
The real savings of living in a no-income-tax state? Roughly 2–4 percentage points compared to high-tax states. Texas saves you 4–6 points versus New York. That’s real money — about $4,000–$6,000 per year on a $100,000 income — but it’s not the tax-free paradise that the marketing suggests. Federal taxes create a floor that no state can escape.
The flip side is more dramatic. New York and D.C. add 4.4% and 4.6% of personal income on top of the federal bite. That’s not a rounding error — on $100,000 of income, it’s an extra $4,400 to $4,600 going to state and local coffers, on top of the roughly $11,000–$12,000 that Washington, D.C. (the federal government, this time) already takes.
The quiet revolution in American taxation isn’t about rates going up or down. It’s about who collects.
In 1948, state and local governments collected 0.5% of personal income in taxes. Federal taxes took 8.5%. The ratio was roughly 17:1 in the federal government’s favor. By 2024, state and local taxes had climbed to 2.3% while federal taxes were at 9.6% — a ratio of about 4:1. States have quadrupled their relative share of the personal tax pie.
This shift happened in two phases. From 1948 to 1980, state income taxes proliferated — the state/local share climbed from 0.5% to 2.1%. Then from 1980 to 2024, the share plateaued in a 2.0–2.9% range. The big expansion of state taxation is over. What remains is a stable layer that sits on top of whatever the federal government happens to be doing.
The practical effect: even in a world where Congress slashes federal rates, the state/local layer has become a permanent fixture. For residents of New York, California, or Maryland, that layer adds nearly half the cost of their federal tax bill.
Americans hand about 12 cents of every dollar to the taxman — and have hovered in that neighborhood for most of the past 76 years. The rate swings more with the economy than with legislation: capital gains drove it to 14.6% in 2022, recessions dragged it below 10% in 2009. By 2024 it settled at 12.0%, almost exactly where it was in 1970.
The real divide is geography. D.C. residents face a 16.9% effective rate — more than double Alaska’s 7.9%. Nine states with no income tax still see rates of 8–12% because federal taxes create a floor nobody can escape. And the slow rise of state/local taxes — from 0.5% in 1948 to 2.3% today — means the federal government’s monopoly on personal taxation has permanently eroded. The next episode asks the obvious follow-up: after taxes take their cut, what do Americans actually get to keep?
