"If he mentions tax cuts 2.0, and I'd love to do it, he will be talking about something that's under process and wouldn't be published until we're well into the campaign later next year," Kudlow said Wednesday on "Bulls & Bears."
As of right now, Kudlow said America is experiencing a "middle-class boom."
"Wage earners, people on the production line, are making faster wage increases than their managers," Kudlow said. "Average income, nationwide, is up $5,000 after tax. The prior two administrations, it was flat."
Among corporations, many have taken advantage of the lower corporate tax rate which Trump cut to 21 percent from 35 percent.
He said America is experiencing a "terrific economy" and "it's not over yet."
Kudlow believes Trump supporters will be out in force Wednesday night at his rally in Battle Creek, Michigan.
"Next year is going to be a terrific year, absolutely terrific year," Kudlow said. "The people in Michigan know a winner when they see one."
