FairTax - Tax Rate - Revenue Neutrality

Revenue Neutrality

A key question surrounding the FairTax is whether the tax has the ability to be revenue-neutral; that is, whether the tax would result in an increase or reduction in overall federal tax revenues. Economists, advisory groups, and political advocacy groups disagree about the tax rate required for the FairTax to be truly revenue-neutral. Various analysts use different assumptions, time-frames, and methods resulting in dramatically different tax rates making direct comparison among the studies difficult. The choice between static or dynamic scoring further complicates any estimate of revenue-neutral rates.

A 2006 study published in Tax Notes by the Beacon Hill Institute at Suffolk University and Dr. Laurence Kotlikoff estimated the FairTax would be revenue-neutral for the tax year 2007 at a rate of 23.82% (31.27% tax-exclusive). The study states that purchasing power is transferred to state and local taxpayers from state and local governments. To recapture the lost revenue, state and local governments would have to raise tax rates or otherwise change tax laws in order to continue collecting the same real revenues from their taxpayers. The Argus Group and Arduin, Laffer & Moore Econometrics each published an analysis that defended the 23% rate. While proponents of the FairTax concede that the above studies did not explicitly account for tax evasion, they also claim that the studies did not altogether ignore tax evasion under the FairTax. These studies presumably incorporated some degree of tax evasion in their calculations by using National Income and Product Account based figures, which is argued to understate total household consumption. The studies also did not account for capital gains that may be realized by the U.S. government if consumer prices were allowed to rise, which would reduce the real value of nominal U.S. government debt. Nor did these studies account for any increased economic growth that many economists researching the plan believe would occur.

In contrast to the above studies, William G. Gale of the Brookings Institution published a study in Tax Notes that estimated a rate of 28.2% (39.3% tax-exclusive) for 2007 assuming full taxpayer compliance and an average rate of 31% (44% tax-exclusive) from 2006–2015 (assumes that the Bush tax cuts expire on schedule and accounts for the replacement of an additional $3 trillion collected through the Alternative Minimum Tax). The study also concluded that if the tax base were eroded by 10% due to tax evasion, tax avoidance, and/or legislative adjustments, the average rate would be 34% (53% tax-exclusive) for the 10 year period. A dynamic analysis in 2008 by the Baker Institute For Public Policy concluded that a 28% (38.9% tax-exclusive) rate would be revenue neutral for 2006. The President's Advisory Panel for Federal Tax Reform performed a 2006 analysis to replace the individual and corporate income tax with a retail sales tax and estimated the rate to be 25% (34% tax-exclusive) assuming 15% tax evasion, and 33% (49% tax-exclusive) with 30% tax evasion. The rate would need to be substantially higher to replace the additional taxes replaced by the FairTax (payroll, estate, and gift taxes). Several economists criticized the President's Advisory Panel's study as having allegedly altered the terms of the FairTax, using unsound methodology, and/or failing to fully explain their calculations.
