After my recent post on “bashing the IRS,” I got several emails and comments asking whether a national sales tax might be a better idea than the flat tax. I’m a big fan of proposals such as the Fair Tax. I’ve debated in favor of the national sales tax, done media interviews in favor of the national sales tax, written in favor of the national sales tax, and even defended the national sales tax in congressional testimony. As far as I’m concerned, we should junk the IRS for some type of single-rate, consumption-base (meaning no double taxation), loophole-free system. The flat tax is the most well-know approach for achieving these goals, but the national sales tax also would work. Indeed, the two plans are different sides of the same coin. A sales tax takes a piece of your income (but only one time and at one low rate) when it is spent, and a flat tax grabs a slice of your income (but only one time and at one low rate) when it is earned.
So why, then, do I devote most of my energies to a sales flat tax? The answer is that I don’t trust politicians. I fear that they will pull a bait-and-switch, and implement something like a Fair Tax but never complete the deal by getting rid of the income tax. The European experience certainly serves as a warning. Nations across Europe began implementing their version of a national sales tax (the value-added tax) in the late 1960s. Voters often were told that other taxes would be eliminated or reduced. But all the evidence shows that VATs simply led to a much higher tax burden and a much bigger burden of government.
By the way, some fans of the Fair Tax say the solution to this problem is an amendment to the Constitution. I fully agree, but then I point out that there are not even enough votes to approve a watered-down balanced budget amendment, so that seems an unlikely path to success. That being said, if we ever reach this point, and are able to repeal the 16th Amendment and replace it with something that unambiguously would stop the politicians from ever burdening America with an income tax, I will gladly offer my support and push a national sales tax
