Feldstein says its important to raise taxes, and this does not mean raising tax rates. He says a lot of revenue is lost through deductions and exclusions, or tax expenditures as they are called. Recovering a large part of this lost revenue was recommended by the President's Bowles-Simpson Deficit Commission. He has a definite proposal that he and his colleagues have studied carefully- limit the reduction in taxes from deductions and exclusions or tax expenditures to 2% of a taxpayers AGI or Adjusted Gross Income. Feldstein says the impact of this proposal would be that taxpayers with incomes between $25,000 and $50,000 would pay an additional $1000 in taxes, and the taxpayers with incomes above $500,000 would pay $40,000 more in taxes. He says the 2% cap is about the reduction in an individual's taxes, not the size of the tax deduction or exclusion.
