The President's Advisory Panel for Federal Tax Reform cited the rebate as one of their chief concerns when analyzing their national sales tax, stating that it would be the largest entitlement program in American history, and contending that it would "make most American families dependent on monthly checks from the federal government". Estimated by the advisory panel at approximately $600 billion, "the Prebate program would cost more than all budgeted spending in 2006 on the Departments of Agriculture, Commerce, Defense, Education, Energy, Homeland Security, Housing and Urban Development, and Interior combined." Proponents point out that income tax deductions, tax preferences, loopholes, credits, etc. under the current system was estimated at $945 billion by the Joint Committee on Taxation. They argue this is $456 billion more than the FairTax "entitlement" (tax refund) would spend to cover each person's tax expenses up to the poverty level. In addition, it was estimated for 2005 that the Internal Revenue Service was already sending out $270 billion in refund checks.
