By greatly increasing the standard deduction, this reform will reduce the number of people who itemize, so you will want to effect how this change will affect incentives, such as incentives to buy a house and incentives to give charitable contributions.
The proposal also includes changes in the itemized deduction rules (page 14 of your document), so make sure to discuss those.
The new phaseout rules will affect effective marginal tax rates at different incomes, so that is another topic to discuss. (Recall our analysis in class.)
You should also talk about how this change affects the distribution of tax burdens – does anyone clearly gain or lose from the reform?
I will upload the tax reform act and proposal is on page 13 to 14
