The current Federal income tax system is broken. Patching up the existing code is pointless. It's time for a fresh approach, a fair approach.
It's time for the FairTax.

Simply put, the FairTax replaces the way we're currently taxed - based on our annual income - with a tax on goods and services. The FairTax is a voluntary “consumption" tax: the more you buy, the more you pay in taxes, the less you buy, the less you pay in taxes.
It's simple.

Everyone pays their fair share of taxes, and with the FairTax rebate, spending up to the poverty level is tax free. The Federal government is fully funded, including Social Security and Medicare, and you don't need an expert to determine your Federal taxes.
It's simple.
