People who claim, like Rush Limbaugh, that no one is undertaxed in this country don't know what they are talking about. Both the rich and the poor are undertaxed. Here is why.
For tax year 2008, IRS figures show that the top half of the country, over 69 million tax returns, contributed in excess of 97 percent of the tax revenue, $1.004 trillion. The bottom half, over 69 million returns, contributed less than 3 percent of the revenue, $27.9 billion, a staggeringly small sum by comparison.
The effective tax rate on the top half was 13.66 percent, on the bottom half just 2.6 percent.
It seems self-evident that the poorer half of the country escaped a lot of taxation, but how?
For one thing, George Bush's creation of the 10% tax bracket in 2001 reduced federal tax revenues from payers in the 10 percent bracket by $42 billion per year. For another, the Earned Income Tax Credit diverts away even more money, now approaching $50 billion per year. These credits wipe out any federal income taxes qualifying filers may owe, and actually reimburse many of them for the payroll taxes they pay, so that many actually have a negative tax rate. This is using the tax code to provide what amount to direct welfare payments, stimulus spending, whatever you want to call it. But it sure isn't "taxes."
But the poorest Americans are not the only beneficiaries.
These credits also percolate far up through the income quintiles. And none penetrate as high as the child tax credit does, relieving the middle classes of taxes to the point that many people in the middle quintile earning between $38,551 and $61,801 also pay little to no federal income tax at all. Created under Newt Gingrich and Bill Clinton and expanded under George Bush, this credit now reduces federal revenues by $143.4 billion per year. People even in the top income quintile, making in excess of $100,000 a year, can qualify for this credit, which also directly reduces their tax bill, and government revenues.
Taken together, the 10% bracket, the EITC and the Child Tax Credit help taxpayers to be sure, but at a cost of nearly $2.4 trillion over ten years to the federal government.
Compare that with the big tax break the top earners in the country enjoy because the payroll tax cap is set at $106,800. Everything they earn after that escapes the 6.2 percent tax. The annual cost of that is now $130 billion, or $1.3 trillion over a decade. The denizens of the top 25 percent of taxpayers, who earn 68 percent of the total adjusted gross income in this country, will doubtless complain that they already contribute 86 percent of the tax revenue.
But the result is that a narrower and narrower band of taxpayers in the fourth quintile (those making between $61,802 and $100,000 per year) and in the top half of the middle quintile (about $52,000 to $61,800), gets squeezed with responsibility for income and payroll taxes without enjoying the relief provided to their poorer fellows who pay very little in taxes, or their richer ones who can afford them.
A ladder needs rungs on it to get from the bottom to the top and back down again, and ours in the upper half are getting worn out.
