Costs 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 costs of compliance. This fact can be used as the basis for practical or moral arguments in favor of tax simplification (see, for example, FairTax), or tax elimination (in addition to moral arguments described above).
