The FairTax is a national Retail sales tax. It is paid whenever the end-user buys anything new at retail. Services are included in being taxed. However used items are not.
The tax is about 23% on everything. The Tax rate is inlcuded in the price so the shelf price of a high-end blender is $100 the actual cost of the blender is $77 and the FairTax is $23. The sales receipt will note this divide on the costs.
