WASHINGTON (Reuters) - U.S. Treasury Secretary Steven Mnuchin said on Thursday that the Trump administration’s upcoming tax plan will not be aimed at lowering income taxes for the wealthiest Americans. “”We are looking for a middle income tax cut. On the high end the plan is to eliminate state and local deductions ... and even if we do end up with a slight reduction on the high end that will be offset by a reduction of deductions so their taxes won’t go down,” Mnuchin said during an interview at a policy forum organized by news outlet Politico. He added that details of the tax reform framework, due for release the week of Sept. 25,  would include a specific rate proposal for the corporate tax rate. “You’re going to see a specific rate proposal in that,” Mnuchin said, adding it would also include details on deduction of corporate interest.
