 Proponents state the FairTax would reduce the number of tax filers by about 86 % (from 100 million to 14 million) and reduce the filing complexity to a simplified state sales tax form. The Government Accountability Office (GAO), among others, have specifically identified the negative relationship between compliance costs and the number of focal points for collection. Under the FairTax, the federal government would be able to concentrate tax enforcement efforts on a single tax. Retailers would receive an administrative fee equal to the greater of $ 200 or 0.25 % of the remitted tax as compensation for compliance costs. In addition, supporters state that the overwhelming majority of purchases occur in major retail outlets, which are very unlikely to evade the FairTax and risk losing their business licenses. Economic Census figures for 2002 show that 48.5 % of merchandise sales are made by just 688 businesses ("Big-Box" retailers). 85.7 % of all retail sales are made by 92,334 businesses, which is 3.6 % of American companies. In the service sector, approximately 80 % of sales are made by 1.2 % of U.S. businesses.
