As part of the sweeping tax changes introduced in the One Big Beautiful Bill (OBBB), metallurgical coal has now been added to the list of critical minerals eligible for the Section 45X advanced manufacturing production tax credit.
This development represents a significant new opportunity for U.S.-based coal producers, particularly those supplying domestic and international steel and metals markets.
Key details of the new credit:
- What’s eligible: The credit applies to metallurgical coal mined within the United States.
- Credit amount: The credit is calculated as 2.5% of eligible production costs.
- Availability: Taxpayers may claim the credit for tax years 2026 through 2029.
- Sales requirement: The mined metallurgical coal can be sold either domestically or internationally — offering flexibility for producers serving global steel and metals customers. Additionally, the coal must be sold to an unrelated party.
This addition highlights the strategic importance of metallurgical coal in U.S. industrial supply chains and reflects a broader federal policy shift to strengthen domestic production of critical minerals and materials essential to manufacturing and infrastructure.
For U.S. coal producers, the Section 45X credit could improve after-tax project economics, support reinvestment in mining operations, and help offset rising regulatory and operational costs.
What this means for your business:
Producers should begin reviewing their cost accounting systems to accurately identify and track eligible production costs starting in 2026.
Companies considering new mining projects or expansions should factor this credit into financial modeling and capital planning.
Taxpayers should evaluate how the credit interacts with other deductions or credits they may claim to optimize their overall tax position.
