Representative Apportionment. Assign to each Senator and Representative a cost based upon the amount of taxes to be raised. Bill each state for their two Senators and X number of Representatives. Let each state decide how to collect the funds. States pay their funds to the treasury.
No longer a need for the IRS.
Yep, I have thought that something similar is the best plan for a while now. Figure a fair method to allocate the federal expenses to the states and then let them figure out how to pay their share of the bill.
This would have the bonus effect of making states more likely to elect fiscally conservative representatives, since sending a bunch of big spenders to Washington will crush their own state budgets.
With the wealth concentrated in certain states, that apportionment, though fine in theory, wouldn’t work out at all. And, to fairly apportion according to wealth would take something IRS-like to determine.
Worthy goal, and at least we could come a bit closer by stopping deductions for local taxes.
