Congress is considering a major increase in the multibillion-dollar tax break for corporate research, but a proposal to change how the credit is calculated is prompting an unusual split among its beneficiaries.

The boost would follow Congress's expansion in December of the "Research & Experimentation" tax credit, which gives companies a credit on their tax bills for part of their research-and-development spending. That version increased the annual subsidy to an estimated $9.3 billion from $7.3 billion, chiefly by adding a new formula for calculating the credit.
