Most people hear “tax credit transfer” and think it’s a clean swap. Developer earns the credit, buyer pays cash for it, everyone walks away happy. That’s the brochure version. The real version involves recapture clauses, indemnification fights, and a pricing negotiation that can drag on for months.
Here’s what’s actually happening in the 45Q tax credit market right now. Carbon capture developers are sitting on credits worth up to $85 per metric ton for point-source capture and $180 per ton for direct air capture with dedicated geologic storage. Those numbers, locked in through the One Big Beautiful Bill Act signed in July 2025, make the economics work on paper. But transferring those credits to a corporate buyer? That’s where the paper meets reality.
Two Paths, Very Different Risk Profiles
The tax code gives developers two distinct mechanisms to move a 45Q tax credit off their books. The first is the Section 45Q(f)(3)(B) election, which lets the equipment owner pass the credit to the party that actually disposes of, injects, or utilizes the captured carbon oxide. This is an operational handoff. The credit follows the carbon, and the party doing the sequestration work claims it directly.
The second path came through Section 6418 of the Inflation Reduction Act. This is the transferability regime, a straight cash-for-credit sale to an unrelated buyer. One transfer per credit, no intermediary buyers allowed. The developer gets cash. The buyer applies the credit against their federal tax liability. Simple enough in concept, but the risk allocation underneath it is anything but.
Where Recapture Changes Everything
And this is the part that makes deal lawyers earn their fees. The 45Q tax credit carries a recapture provision. If captured carbon oxide leaks or ceases to be properly stored within the recapture period, previously claimed credits get clawed back. Under the final IRS regulations for Section 6418 transfers, that recapture liability largely falls on the buyer, not the seller.
Read that again. You’re the corporate buyer. You paid cash for a credit generated by someone else’s equipment, stored in someone else’s geologic formation, and if something goes wrong underground three years from now, you’re on the hook.
This is why most sophisticated transfer agreements include contractual indemnification. The IRS explicitly permits sellers and buyers to negotiate indemnity arrangements between themselves. In practice, the developer agrees to make the buyer whole if a recapture event occurs. But an indemnity is only as good as the counterparty standing behind it. A developer that runs into financial trouble can’t honor an indemnification clause it signed two years earlier.
Insurance, Pricing, and the Risk Premium
Tax credit insurance has stepped in to fill that gap. Property and casualty carriers now offer policies that cover recapture risk, ITC valuation disputes, and excessive credit transfer penalties. That 20% penalty for excessive transfers, by the way, can be waived if the buyer demonstrates reasonable cause, but proving reasonable cause after the fact isn’t a position anyone wants to be in.
All of this risk gets priced into the transaction. A 45Q tax credit with strong indemnification, solid insurance coverage, and transparent documentation from a well-capitalized developer will trade at a tighter discount to par. Credits from early-stage developers with thinner balance sheets and less operating history? Those trade at steeper discounts, sometimes significantly so. The buyer’s risk appetite directly shapes the economics of every deal.
Why Structure Matters More Than Credit Value
The dollar-per-ton headline number grabs attention, but the transfer structure determines whether a project actually gets financed. Developers who understand this build their deals around it. They commission capture equipment with an eye toward the 12-year credit window. They negotiate storage contracts that minimize recapture exposure. They secure registration numbers from the IRS before approaching buyers, because no buyer wants to start the clock on due diligence without that baseline documentation in place.
For corporate buyers evaluating 45Q tax credit opportunities, the diligence process matters as much as the price. Understanding the structural advantages and emerging risk factors in this market is becoming a baseline requirement, not a nice-to-have (for a deeper look at the diligence landscape, Reunion Infra’s analysis of the structural advantages shaping this emerging credit class is worth reading).
Structuring 45Q Tax Credit Transfers for Long-Term Risk Management
The 45Q tax credit market is maturing fast. But maturity doesn’t mean simplicity. Every transfer carries embedded risk, and the developers and buyers who structure around that risk, rather than ignoring it, are the ones closing deals.
