Sorry, but you are badly misinformed.
The flat tax is still an income tax, and there is NO WAY the IRS will go away so long as we have any form of income tax. Most of the tax code verbiage is about defining and debating the meaning of “income.” Ergo, income tax REQUIRES an IRS.
FairTax legislatively ABOLISHES the IRS.
In its place, a Federal agency will be created to monitor the 50 states for compliance with the FairTax.
Here is the FReedom news about FairTAx:
NO INDIVIDUAL AMERICAN WILL EVER BE QUESTIONED OR AUDITED BY AN IRS AGENT!
Individual Americans are no longer in the tax loop, since all tax collections will be made at the retail store level.
Under FairTax, Feds will monitor states’ collection of the tax. Businesses and states will be compensated for collecting the tax.
A whole lot of bureaucrats are going to have to find legitimate work when FairTax is put in place!
And will necessarily result in the creation of another bureaucracy to track every American, bank acccounts, addresses, game the numbers on average expenditures on the things that never should have been taxed in the first place, and to issue all those payments--and monitor the inevitable fraud. How many of the IRS people who already do this sort of thing will make the shift? Most, if not all, and then some.
Just do away with it.
Income equals X, multiply by a fraction, Y, and send a check. It doesn't get any simpler than that.
It doesn't require an army to implement.
And one more thing, YOU WON"T GET RID OF THE IRS ANYWAY: there are tariffs and excise taxes to collect, not just the income tax.
