A few weeks ago, the Internal Revenue Service released data on tax year 2003. They show the top 1 percent of taxpayers, ranked by adjusted gross income, paid 34.3 percent of all federal income taxes that year. The top 5 percent paid 54.4 percent, the top 10 percent paid 65.8 percent, and the top quarter of taxpayers paid 83.9 percent.
Not only are these data interesting on their own, but looking at them over time shows the share of total income taxes paid by the wealthy rose even as statutory tax rates fell sharply. Growing international data show the same trend.
On the first point, we see that in 1980, when the top statutory income tax rate went up to 70 percent, the share of income taxes paid by the top 1 percent of taxpayers was just 19.3 percent. After Ronald Reagan’s tax cut of 1981, which reduced the top rate to 50 percent — a massive giveaway to the wealthy, according to the political left — the percentage of income taxes paid by the top 1 percent rose steadily.
By 1986, the top 1 percent’s share of all federal income taxes rose to 25.7 percent. That year, the top statutory tax rate was further cut to 28 percent — another huge giveaway, we were told. Yet the share of income taxes paid by the top 1 percent continued rising. By 1992, it was up to 27 percent.
Of course, it would be a mistake to conclude tax increases will not raise the wealthy’s tax share or that tax rate cuts always will. Nevertheless, it is remarkable that the percentage of federal income taxes paid by the top 1 percent of taxpayers almost doubled when the top income tax rate fell by half.
A common liberal retort to these data is that they exclude payroll taxes, which are assumed to be largely paid by the poor. However, it turns out that when one includes payroll taxes in the calculations, it has far less effect on the distribution of the tax burden than most people would assume, because the wealthy pay many of those taxes, too.
In a 2004 paper to the American Statistical Association, IRS economists Michael Strudler and Tom Petska calculated percentiles data that included both income taxes and Social Security taxes. In 1999, the top 1 percent paid 23.3 percent of combined payroll and income taxes, the top 10 percent paid 52.2 percent and the top 20 percent paid 68.2 percent.
In recent years, some foreign countries have also published tax shares data. They show the same trend of higher and higher burdens on the wealthy even when tax rates are cut sharply.
For example, according to Her Majesty’s Revenue & Customs, the share of total income taxes paid by the top 1 percent of taxpayers was 11 percent in the United Kingdom in 1979, when the top income tax rate was 83 percent. Prime Minister Margaret Thatcher cut that rate to 60 percent and by 1987 the share of income taxes paid by the top 1 percent had risen to 14 percent. The top rate was cut again to 40 percent, where it still stands, and the share of income taxes paid by the top 1 percent continued rising to the present 21 percent.
Statistics Canada recently released a study of tax shares in that country. It shows the share of federal income taxes paid by the top 10 percent of taxpayers reached 52.6 percent in 2002 — almost exactly the same as is paid by the top 10 percent in the U.K. However, the top income tax rate in Canada is just 29 percent. (Provincial tax rates in Canada are very substantially higher than those of U.S. states.)
Finally, we now have data from the Australian Taxation Office. In 2003, they show the top 5 percent of taxpayers paying 30.2 percent of all income taxes, the top 10 percent paying 41.8 percent and the top 25 percent paying 63.8 percent. But the top income tax rate in Australia is 47 percent. Thus we see the country with the highest top rate brings in the smallest overall percentage of income taxes from its richest citizens.
At some point, those on the left must decide what really matters to them — the appearance of soaking the rich through high statutory tax rates that may cause actual tax payments by the wealthy to fall, or lower rates that may bring in more revenue to pay for government programs to aid the poor?
Sad to say, the left nearly always votes for appearances over reality, favoring high rates that bring in little revenue even when lower rates would bring in more.
