Tax
Cost of compliance

Although governments must spend money on tax collection activities, some of the costs, particularly for keeping records and filling out forms, are borne by businesses and by private individuals. These are collectively called costs of compliance. More complex tax systems tend to have higher compliance costs. This fact can be used as the basis for practical or moral arguments in favor of tax simplification (such as the FairTax or OneTax, and some flat tax proposals).
