Mark Cuban said on Wednesday that a cut in the U.S. corporate tax rate would have little to no effect on his investment decisions. Bills before both the U.S. Senate and the House of Representatives would cut the corporate rate from the current 35 percent to 20 percent. President Donald Trump and other supporters of the tax cut bills say reducing corporate and other taxes would boost the U.S. economy by freeing up capital that would be invested in job-creating industries.
