If it's April, it must be time for... Tax Freedom Day. According to the folks at the Tax Foundation, Tax Freedom Day is the day on which "the nation has finally earned enough to pay all the taxes that will be due for that year." The calculation is a pretty simple one: as the Foundation describes it, they're just "dividing the nation's total tax payments by the nation's income." In 2007, that figure is 32.7%. So, the report concludes, Tax Freedom Day is 32.7% of the way through the year in 2007, which would be April 30.
The Center on Budget and Policy Priorities explains why Tax Freedom Day is a meaningless concept. For one thing, the average percentage of income paid towards federal taxes, as reported by the Tax Foundation, is actually higher than the percentage that all but the highest income quintile really pay. The wealthiest have incomes so high that they pull up the average above what people in the middle pay. The statistic also fails to capture certain sorts of income. Also, if the percentage has gone up as the Tax Foundation claims, it's because of rising income at the very top (which leads to more taxes paid in higher income brackets), not because of higher taxes.
Unfortunately, every year a few media outlets gullibly (or knowingly) write this story in a way that makes readers think the statistic says something about the "typical" American's tax level. Some media outlets use the Tax Freedom Day as a rhetorical tool to assert that our taxes are too high. Others simply regurgitate the report's results without making the faintest effort to evaluate what it all means. And a few worthy reporters bring up the topic just to point out that the data doesn't mean anything.
