Norway's largest salmon farmers have expressed strong opposition to the government's new 'salmon tax' plans, despite the reduced basic rate and initial allowance. They argue that the tax, imposed on salmon sales in addition to corporation tax, will deter investment and harm the industry, potentially negatively impacting the nation as a whole. Critics believe the proposals fail to understand the unique aspects of salmon farming, such as its integrated nature and environmental restoration after operations. Major companies like Mowi, SalMar, Grieg Seafood, and Cermaq are hopeful that the proposals may not pass the Norwegian parliament due to inter-party disagreements.
