Trump is scheduled to meet this week with top business leaders to discuss his plan to overhaul the U.S. tax code, a White House official said on Monday.

Trump will meet with executives from companies like Amazon, Boeing and General Electric, the official said, speaking on condition of anonymity because the meeting was private.

The official declined to provide any details on what the meeting would discuss.

The president-elect has long been pushing for a tax overhaul that would eliminate the top rate on corporate income taxes from 35% to 20%, a proposal that critics and corporate supporters have said could harm the economy and create an incentive for companies to keep more of their profits overseas.

A new Tax Policy Center report released earlier this month showed that a 20% rate would cost the economy $1.5 trillion over a decade and hurt job creation.

That’s a stark contrast to President Barack Obama’s plan to lower the corporate tax rate to 20%.
