"In November 2005, the President's Advisory Panel on Tax Reform presented two potential reform proposals: a simplified income tax (SIT) and a direct consumption tax proposal (the growth and investment tax, or GIT). Both proposals would eliminate itemized deductions while allowing, for all taxpayers, a credit for mortgage interest deductions and deductions for charitable contributions and health insurance. Both proposals substitute credits for personal exemptions and standard deductions. Both would allow greatly expanded tax-preferred savings plans. SIT would eliminate taxes on dividends and most capital gains from corporate stock, simplify depreciation and allow expensing (deducting costs immediately) for small business, and alter the international tax regime. GIT, as a consumption tax, would allow expensing of all investment. GIT also includes a tax on passive capital income (dividends, interest, and capital gains). […] Transition problems present difficulties; the main issue with the SIT would probably be in the loss of deductions for homeowners with large houses and mortgages. These transition problems in the SIT are minor, however, in comparison with the significant problems in the GIT arising from the loss of depreciation deductions, interest deductions, and deductions for the recovery of inventory. This report will not be updated."
