WASHINGTON—Congress is poised to create a new corporate minimum tax, and pension advocates, renewable-energy backers and manufacturers are pushing for changes before the plan is finalized.
The tax is aimed at companies, such as Amazon.com Inc., that report large profits to shareholders but—legally—pay relatively little in taxes. It would impose a minimum 15% federal tax rate on many companies with at least $1 billion in profits, based on the income reported to investors.
