The Biden administration has finalized rules for a 25% tax credit aimed at semiconductor manufacturing projects, broadening eligibility under the 2022 Chips and Science Act. The expansion includes companies producing wafers and chipmaking equipment, as well as solar wafers, which could enhance domestic production. However, facilities producing underlying materials like polysilicon remain excluded. The tax credits are part of a larger subsidy framework, which includes $39bn in grant funding and $75bn in loans. Mike Schmidt, director of the Commerce Department’s chips office, stated: “Our goal is to give you the minimum amount of money necessary to get you to expand on our shores.” The Congressional Budget Office initially estimated the tax credits would cost $24bn, but recent projections suggest it could exceed $85bn, indicating a significant increase in investments in American manufacturing.
