K. I. S. S.:

The 30-Cent Tax Premium: Tax compliance employs more workers than Wal-Mart, UPS, McDonald's, IBM and Citigroup combined. (ARTHUR B. LAFFER, 4/17/11, WSJ)

There is a lot more to taxes than simply paying the bill. Taxpayers must spend significantly more than $1 in order to provide $1 of income-tax revenue to the federal government.

To start with, individuals and businesses must pay the government the $1 in revenue plus the costs of their own time spent filing and complying with the tax code; plus the tax collection costs of the IRS; plus the tax compliance outlays that individuals and businesses pay to help them file their taxes.

In a study published last week by the Laffer Center, my colleagues Wayne Winegarden, John Childs and I estimate that these costs alone are a staggering $431 billion annually. This is a cost markup of 30 cents on every dollar paid in taxes. And this is not even a complete accounting of the costs of tax complexity.
