What the Taxpayer-Level Restriction Actually Means for 45Q
The FEOC framework operates through more than one type of restriction, and it's worth being precise about which one applies where. The taxpayer status restriction disallows the credit entirely if the entity claiming it is itself a Specified Foreign Entity or a Foreign-Influenced Entity, and this restriction applies broadly across credit types, including 45Q, for credits claimed in taxable years beginning after July 4, 2025. This is a different and generally simpler test than the material assistance cost ratio that applies to 48E, 45Y, and 45X, since it turns on who owns and controls the taxpayer, not on the sourcing of every manufactured component in a project's supply chain.
That distinction matters practically. A CCS developer doesn't need to run a component-by-component material assistance calculation the way a solar developer does. But it does need to confirm, and be able to document, that no Specified Foreign Entity holds the ownership, board appointment rights, or debt position that would trigger Foreign-Influenced Entity status, using the same 25% equity, 15% debt, and board control thresholds that apply elsewhere in the FEOC framework.
Why This Matters More for Ethanol and Biofuel-Adjacent CCS Projects
This is particularly relevant for CCS projects tied to ethanol and biofuel production, where ownership structures often involve joint ventures, cooperative arrangements, and multiple layers of investment that can make a clean FEOC determination less straightforward than it looks at first glance. As we discussed in Beyond the Hype: Why Ethanol Plants are the Next Frontier for High-Quality CDR Removals, the credibility of carbon capture claims already depends on rigorous documentation to satisfy buyers and regulators. FEOC compliance adds another layer to that same documentation discipline: a project can have an airtight carbon accounting methodology and still lose the credit entirely if the ownership structure funding it includes a prohibited foreign entity.
Where the Effective Control Test Applies as Well
Beyond taxpayer status, the effective control provisions that we've covered in the context of 48E projects apply conceptually to 45Q arrangements as well, wherever a contract or licensing arrangement gives a Specified Foreign Entity meaningful influence over a facility's operations. For CCS specifically, this is worth watching in technology licensing agreements, since capture technology providers with foreign ownership structures could create effective control exposure through long-term licensing or service arrangements, similar to the equipment servicing exposure we described in The 2026 Supply Chain Trap: Surviving FEOC Limits and the Direct Pay "Haircut" Under Section 48E.
What CCS Developers Should Do Now
The practical starting point is a straightforward ownership review: mapping every equity holder above meaningful thresholds, every debt holder, and every party with board appointment rights, and confirming none of them trip the Specified Foreign Entity or Foreign-Influenced Entity definitions. For projects with technology licensing agreements tied to capture equipment, that review should extend to the licensor's ownership structure as well, not just the project entity's own cap table. This is a lighter lift than the material assistance calculations solar and storage developers are running, but it's not optional, and it's the kind of gap that public company ownership questions we described in Why Public Companies Can't Actually Certify Their Own FEOC Status can make harder to close cleanly than developers expect. Getting ahead of this now, before a transfer transaction or Direct Pay election forces the question, is considerably easier than discovering a gap in the middle of closing diligence.
