Broadening the tax base can involve subjecting more types of income to taxation and/or eliminating or reducing tax deductions. Locate at least two tax reform proposals that are currently being debated where itemized deduction provisions would be modified. In an e-mail to your professor, evaluate each of the proposals in terms of costs and benefits and compare them to current law.
