Abolish it. Completely, totally, drive a stake through its heart and kill it.
Replace the entire tax code with a new tax code that takes one page or less to explain. Make it so EVERYONE pays, period. No outs, no exceptions, no exemptions.
Whether it's the "fair tax" a flat tax, national sales tax - I don't care. As long as EVERYONE pays, the bill is one page or less, and it completely eliminates the IRS in every way.
That's the only way IMO to solve this problem.
Fair Tax yes, flat tax no. Flat tax is what our current tax started as. Fair tax puts the power of taxation back in the hands of the People, where a “volutary” tax belongs. It incentivizes the Federal Government to really truly get out of the way of the economy. The more they muck it up, the lower the tax revenue, so if they want to increase revenue, there has to be real jobs being created, not government jobs.
It’ll require a Constitutional Amendment shoved upon the FedGov against their will from the States. It will have to remove the 16th, and if we’re wise, we’ll include language limiting the percentage right in the amendment, AND language limiting the Federal spending to specific Constitutional items.
