[null and void]

Gone are all the 1099, W2, etc. forms.
The 1040 would be 3 lines: Total income, minus $10,000, your tax.

I think you meant to add "times 0.02" (or whatever the flat rate turns out to be).

See how europe taxes everyone with a flat tax that goes up and up and up plus all other taxes / fees. It starts out small then balloons.

Correct. Just trying to keep it simple.
