Today's federal income tax system is highly pro­gressive, with taxpayers at the top of the income spectrum paying higher rates than those in the middle and bottom. The current tax code has six tax brackets with rates ranging from 10 percent (for taxable income up to $16,700) to 35 percent (for taxable income above $372,950 for married couples).

President Barack Obama's budget and the budget resolution adopted by Congress[1] would further in­crease progressivity by raising the tax rates of married couples who earn more than $250,000 a year and singles who earn more than $200,000.

Progressivity discourages hard work, savings, investing, and entrepreneurship. Discouraging these catalysts of economic growth is always counterproductive, but doing so during a severe economic recession is particularly irresponsible.

To make the tax code less progressive and encourage economic growth, Congress should scrap plans to increase tax rates on top earners and instead reduce the number of brackets and lower the rates on those that remain.

Income Tax Highly Disproportionate

A decreasing number of high-income taxpayers are increasingly paying the entire income tax bill.[2] According to the Congressional Budget Office (CBO), the top 20 percent of all income earners paid 86.3 per­cent of all income taxes in 2006.[3] This was an all-time high and significantly higher than in 2000, before the 2001 and 2003 tax cuts went into effect.[4]

The drastically progressive income tax code means that high-income taxpayers pay dispropor­tionately higher taxes compared to lower-income taxpayers. Take the average family of four, which qualified for the top quintile of income earners if it earned at least $142,000 in 2006 (the most recent year for which data are available). For 2006, the family paid income taxes of $20,078, and its effec­tive income tax rate-total income taxes paid after deductions and credits divided by income-was 14.1 percent. (See Chart 1.)

A family of four that earned the minimum amount to be included in the second-highest income quintile made $94,800. Its effective income tax rate was 6.0 percent-less than half the top quintile's rate-and its tax bill was $5,688.

Even though the family in the top quintile earned 50 percent more than the family in the sec­ond quintile, it paid 253 percent more in income taxes. (See Chart 2.)

The statistics are even more astounding when one compares a family in the top quintile to fami­lies in the middle and lower quintiles. A family of four that earned $64,200, the minimum amount to be classified as middle income, had an effective income tax rate of 3 percent-almost five times lower than the top quintile's rate-and paid $1,926 in income taxes.

The family in the top quintile's income was 122 percent higher than the middle-income family's, but they paid a staggering 943 percent more in income taxes.

Compared to the bottom 40 percent of income earners, taxpayers in the top quintile pay much higher taxes because taxpayers in the bottom two quintiles generally pay no income taxes at all. In fact, they receive payments through the tax code in the form of "refundable credits."[5]

The effective income tax rate for a family of four in the bottom quintile that earned up to $37,800 was -6.6 percent. This means that the average fam­ily in this quintile received almost $1,300 in income through the tax code.

An average family of four in the second-lowest quintile had an effective income tax rate of -0.8 percent. This family earned up to $64,200 and received an average of $408 of income through the tax code.

Progressivity Knows No End

It is obvious that high-income fam­ilies pay substantially higher taxes than low and middle-income families pay, but the tax code is also highly progressive among high earners because rates continue to rise. In 2006, the top 35 percent rate kicked in at $336,550, which is above the threshold for a family of four to qual­ify for the top 5 percent of earners. As taxpayers move into higher income brackets, they lose the ability to take certain deductions, and the alterna­tive minimum tax (AMT) reduces the value of other deductions.

A family of four that earned enough to be in the top 1 percent of all income earners made $664,600 in 2006 and paid an effective income tax rate of 19 percent. Its tax bill for the year was $126,274.

A family that made enough to qualify for the top 5 percent of income earners made $268,800 and paid an effective income tax rate of 17.5 per­cent. Its tax bill was $47,040.

The family in the top 1 percent earned 147 percent more than the fam­ily in the top 5 percent but paid 168 percent more in taxes. (See Chart 3.)

The difference is even larger when comparing a family in the top 10 per­cent to the family in the top 1 percent. A family in the top 10 percent earned $196,200 in 2006 and paid $31,392 in taxes for an effective income tax rate of 16 percent. The family in the top 1 percent earned 239 percent more than this family-and paid more than 300 percent more in taxes.

Stifling Growth

Progressive taxation dampens economic growth because it lessens the incentives of investors, savers, and entrepreneurs to take on new risk and reduces incentives for workers to put in longer hours. Peo­ple work longer hours and extra days to earn addi­tional income, and progressive taxation means they keep less of what they earn as their income rises. Not surprisingly, many workers decide that the extra effort is not worth it.

Savers and investors forgo spending their income today for the chance to earn high returns in the future, but progressive taxation means that as their returns increase, they pay higher tax rates and their after-tax returns decline. This makes spending their income now more attractive, and both investment and savings decline.

The risks of starting a new business are high, but the rewards often outweigh those risks-and not just for entrepreneurs. Workers and the economy as a whole benefit when entrepreneurs take on new risk, because the small businesses they create pro­vide jobs for millions of Americans and often grow into larger businesses that create even more jobs.

Small businesses rely heavily on the profits they earn in the early stages of their development to fund growth and expansion. Progressivity takes more and more of these much-needed profits as businesses grow. This creates an entry barrier for many would-be entrepreneurs, discouraging many of them from taking risks to bring their ideas to market.[6]

Stop Progressivity Now by Making Taxes Flat

Even though the tax code is already steeply progressive, President Obama proposed in his budget, and Congress adopted in its budget resolution, a measure to make it even more punitive by raising the income tax rates for couples earning over $250,000 a year ($200,000 for singles) back to levels that applied before the 2001 and 2003 tax cuts. Under this plan, the top two rates will be 36 percent and 39.6 percent, compared to today's 33 percent and 35 percent.

To avoid increasing the damage that tax pro­gressivity has already done to the economy, Con­gress should:

  • Abandon the plan to raise tax rates on top earners and extend the 2001 and 2003 tax cuts for all taxpayers, and
  • Reduce the progressivity of the tax code by eliminating severalbrackets and lowering the rates on those that remain.

Congress should aim for a tax code that treats taxpayers more equally: one that more closely resembles a flat tax. A tax code that has fewer tax brackets and lower rates would not punish success as a progressive taxation scheme does. It would tax all income similarly, so there would be no impediment to earning more.

Under a flatter tax system, those who earn more income still pay more taxes than those who earn less, but that difference will be more proportional to income. Under a flat tax that taxes all income at one rate, a family that earned 100 percent more than another family would pay 100 percent more in taxes[7]-not nearly 1,000 percent more, as is the case under the current tax code.


Increasing the progressivity of the tax code threatens to further stifle economic growth. A code more in line with the flat tax is necessary to remove the barriers that block entrepreneurship and inno­vation. Regrettably, President Obama and Congress have chosen to follow liberal orthodoxy and put up more road blocks to economic growth by increasing the progressivity of the tax code through higher rates on top earners. They should look to the flat tax for inspiration instead.
