Critical Minerals Investment Tax Modernization Act of 2025

The Critical Minerals Investment Tax Modernization Act of 2025 modifies the federal tax code to allow mining companies extracting specific critical minerals - including the 15 lanthanide elements and scandium - to claim a 22% tax deduction (known as percentage depletion) on their mining operations. This deduction reduces taxable income for qualifying companies, directly affecting firms focused on these minerals used in technologies like electronics and clean energy infrastructure. The change applies to tax years beginning after the bill's enactment date. The legislation targets a narrow tax provision without altering broader tax policy or funding mechanisms.
