President Donald Trump on Wednesday proposed slashing the U.S. tax rate on corporate and pass-through business profits to 15 per cent from 35 per cent or more.
The administration is determined to get the tax reform done by this year, Treasury Secretary Steven Mnuchin said at press conference.
The promise of a massive tax cut has been at the core of the post-election rally, which has driven Wall Street's indexes to record highs. However, the rally has stalled of late due to a lack of clarity on Trump's policies and the failure of his healthcare reform bill.
