The administration rolled out a 'tax receipt' web page on Monday so people can see where their taxes are going in state spending, coinciding with the deadline day for Americans to file their annual returns. But while the White House made it easy to see how much -- or how little -- lower-income and middle-class earners pay to Uncle Sam, it made it difficult for ordinary taxpayers to learn how much the wealthy pay toward federal spending. The online receipt was set up to itemized what Americans' income, Social Security and Medicare taxes actually pay for, broken down along a long list of categories. It also provides a handful of example calculations. The White House's typical $80,000 earner who is married and filing jointly, for instance, pays $4,590 in federal income tax. Of that, more than $1,130 is devoted to national defense, another $1,030 for health care-related costs, and $792 to a category that includes food stamps, housing assistance and unemployment insurance.
