Na revista Economist, uma vantagem, entre outras, da taxa única de impostos:

Because every dollar is taxed at the same rate, it does not matter to the tax collector how many dollars are going to whom. Thus, in principle, the taxman could simply withhold 20% of a company's payroll, without needing to know who was paid what. (...) In America, for example, the tax collector needs to tax the wage packets of 130m or more employees, rather than simply taxing the payrolls of 8m or so enterprises.

Menores custos de cobrança. Menos funcionários públicos. Redução da despesa pública!
