23 countries have made the Flat Tax work.
And here is how it would work for corporations and for individuals … and with a 17% rate.
So, I guess more reading is needed.
Flat tax with deductions [from Wiki]
US Congressman Dick Armey has advocated a flat tax on all income in excess of an amount shielded by household type and size. For example, draft legislation proposed by Armey would allow married couples filing jointly to deduct $26,200, unmarried heads of household to deduct $17,200, and single adults, $13,100. $5,300 would be deducted for each dependent. A household would pay tax at a flat rate of 17% on the excess.
Businesses would pay a flat 17% rate on all profits. Others have put forth similar proposals with various rates and deductions. Armey defined income to include only salary, wages, and pensions; capital gains and all other sources of wealth appreciation were excluded from taxation under his proposal.[4]
While campaigning for the American presidency in 1996 and 2000, Steve Forbes called for replacing the income tax - which would have included a repeal of the 16th Amendment - by a tax at the flat rate of 17% of consumption, defined as income minus savings, in excess of an amount determined by the type and size of the household.[citation needed] For example, the exempt amount for a family of four would be $42,000 per year.
Modified flat taxes have been proposed which would allow deductions for a very few items, while still eliminating the vast majority of existing deductions. Charitable deductions and home mortgage interest are the most discussed exceptions, as these are popular with voters and often used.
