The Complete Guide to 45Q Tax Credits for Industrial Carbon Capture
The 45Q carbon capture tax credit has become the single most impactful federal incentive for industrial emissions reduction. Under the OBBBA 2025, mineralization pathways now qualify for the same $85/ton rate as geological storage, creating a dual-revenue baseline that transforms capture from a cost center into a profit center.

What Is the 45Q Tax Credit?
The 45Q tax credit, codified under IRC Section 45Q and IRS Subpart RR, provides a federal income tax credit for each metric ton of qualified CO₂ captured and either permanently sequestered or utilized. It is the only federal incentive program that makes industrial carbon capture financially viable.
For most industrial operators, the 45Q credit is claimed via Form 8933 (Fuel Mix Credit and the Section 45A, 48C, 45Q, 45X Credits). The credit is calculated per ton of CO₂ captured and varies based on the sequestration or utilization pathway.
Key rate: $85/ton for mineralization or geological storage (post-OBBBA 2025); $85/ton for industrial utilization (post-OBBBA 2025).
