In a December 26 Wall Street Journal editorial here or here (no subscription required), Leo Linbeck, chairman of Fairtax.org, defended the virtues of the FairTax, a proposal to replace the current income tax with a national retail sales tax.
As I've said many times, the FairTax idea is an excellent one, with many favorable attributes, which Mr. Linbeck highlights in his piece. My main questions, which he does not address, are as follows:
1. It is highly unlikely that we can switch from an income to a national sales tax "cold turkey." Rather, we probably will have an extended period where there is both an income and a sales tax, a period likely to be extended by politicians for quite some time. I predict that in the long-run, we will end up with both taxes. How do we manage the transition and not end up with a worse tax situation than we have now?
2. Although the FairTax folks have estimated carefully how much revenue (net of the "prebate") their proposal will raise, I worry that they are overly optimistic. I think they underestimate how much people's behavior will change under a heavy sales tax. Keep in mind that the proposed FairTax rate of 23% does not include state or local sales taxes. If, as is likely, these states and localities convert to a FairTax for their own revenue needs, I can see the "all-in" FairTax rate approaching 40% or more in high tax states like New York and California. At rates like this, won't citizens become surprisingly creative at avoiding the tax? If so, how much higher will the rate have to go to raise the required revenue?
3. I don't see too many Democrats supporting the FairTax. If this site ("Democrats for FairTax") is indicative, broad Democratic support for the FairTax is decades if not centuries away.
As we enter a (likely) period of Democratic dominance in national politics, "Republican" tax proposals like the FairTax are simply not going to be enacted. How will the FairTax ever command the broad support required for passage?
