In my view, we simply cannot risk having both a national income tax and a national sales tax in place at the same time." Individuals under the current system who accumulated savings from ordinary income (by choosing not to spend their money when the income was earned) paid taxes on that income before it was placed in savings (such as a Roth IRA or CD). When individuals spend above the poverty level with money saved under the current system, that spending would be subject to the FairTax. People living through the transition may find both their earnings and their spending taxed. Critics have claimed that the FairTax would result in unfair double taxation for savers and suggest it does not address the transition effect on some taxpayers who have accumulated significant savings from after-tax dollars, especially retirees who have finished their careers and switched to spending down their life savings. Supporters of the plan argue that the current system is no different, since compliance costs and "hidden taxes" embedded in the prices of goods and services cause savings to be "taxed" a second time already when spent. The FairTax would also eliminate what some claim to be the double taxation on savings that is part of estate taxes. In addition, the FairTax legislation adjusts Social Security benefits for changes in the price level, so a percentage increase in prices would result in an equal percentage increase to Social Security income. Supporters suggest these changes would offset paying the FairTax under transition conditions. In contrast to ordinary savings, money in tax-deferred savings plans such as IRA, 401k, etc. would be withdrawn tax-free. There is currently $11 trillion in such accounts. This represents future tax revenue owed to the federal government under the income tax system, which has been estimated at $3 trillion. This revenue would then fall under the FairTax system for collection. During the transition, many or most of the employees of the IRS (105,978 in 2005) would face loss of employment. The Beacon Hill Institute estimate is that the federal government would be able to cut $8 billion from the IRS budget of $11.01 billion (in 2007), reducing the size of federal tax administration by 73%. In addition, income tax preparers (many seasonal), tax lawyers, tax compliance staff in medium-to-large businesses, and software companies which sell tax preparation software (such as Drake Software, TaxCut, and TurboTax), could face significant drops, changes, or loss of employment. Proponents state the income tax industry often provides year-round services for financial planning and investment, which is expected to increase under the FairTax proposal and could offset some of these changes.
