The tax rate in HR25 is 23%, not 30%.....
The Fair Tax rate is 23% when stated as an "inclusive" rate, which is the correct way to compare it with income taxes since they are normally stated at inclusive rates.
The "exclusive" rate, which is how sales taxes are normally stated, is 29.87%.
If you purchase a $100 item under the Fair Tax, you pay $129.87, not $123.
Only by taxing the item, then taxing the tax, then taxing the tax on the tax, then taxing the tax on the tax on the tax...
That's how the Fair Tax cult pretends 30% is 23%.
