Presidential nominee Mike Huckabee has proposed eliminating the IRS and enacting a fair tax.
The FairTax plan is a comprehensive proposal that replaces all federal income and payroll based taxes with an integrated approach including a progressive national retail sales tax, a prebate to ensure no American pays federal taxes on spending up to the poverty level, dollar-for-dollar federal revenue neutrality, and, through companion legislation, the repeal of the 16th Amendment. www.fairtax.org
Considering what the IRS costs to operate and the fact that this fair tax would virtually ensure that all citizens pay taxes including illegal immigrants I don't really see a downside. Unless the Government starts heavily taxing necessities like meat, milk, and medication unfairly then that would be a problem. And how would this affect the State governments ability to tax.
But just imagine not having to dread April 15 and never wondering about an audit from the feds.
