This [tax compliance] 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.
David Keating of the National Taxpayers Union provides a useful perspective on how big the tax compliance industry is. According to his research, as of 2009 the income-tax industry employed "more workers than are employed at the five biggest employers among Fortune 500 companies—more than all the workers at Wal-Mart Stores, United Parcel Service, McDonald's, International Business Machines, and Citigroup combined." Without diminishing in any way the professionalism of tax attorneys, accountants and financial planners, all of these efforts produce nothing other than, well, tax compliance.
