Business groups urge senators to oppose 'insourcing' bill

“There's not one Republican that should be voting against this,” Sen.

But the PACE Coalition — which includes the Business Roundtable, the Information Technology Industry Council, the National Association of Manufacturers, the National Foreign Trade Council and the U.S. Chamber of Commerce — says there are legitimate business reasons for companies to shift operations, something it says the Senate bill doesn’t take into account.

“Relocation of certain business operations can result in greater production in the United States when it results in cost savings that can increase the international competitiveness of U.S.-made goods and services,” the groups wrote.

“In contrast, disallowing a deduction for a legitimate cost of doing business would inject even more uncertainty into business planning, add additional complexity to the tax code and further increase costs for U.S. companies, making them less competitive in the global marketplace.”

Senate Democrats and Republicans have been going back and forth in recent weeks over various tax proposals, as both sides seek to gain an advantage in an election year.
