Transferable Tax Credits: Turning a Credit You Cannot Use Into Closing Capital

A tax credit is only worth face value to someone with enough tax liability to use it. Plenty of real estate partnerships do not: sheltered by depreciation, holding foreign or tax-exempt investors, or simply not generating the liability the credit would offset. For those sponsors, an energy incentive used to be theoretical — visible in a model, unreachable in practice, unless the project was large enough to support a tax-equity partnership.

Section 6418 changed that. It permits an eligible taxpayer to transfer all or a portion of certain clean energy credits to an unrelated taxpayer for cash. The buyer gets the credit; the seller gets money. It survived the 2025 tax legislation with its framework intact, subject to restrictions including a bar on transfers to prohibited foreign entities.

Why it matters more than tax equity for mid-market deals

Tax equity is a partnership structure. An investor is admitted, allocations are engineered so credits and accelerated depreciation flow to them, and the arrangement carries a flip, a put or call, ongoing partnership accounting, and a legal budget to match. It works, and for very large projects it remains the efficient route. But the fixed cost is high enough that it has historically ruled out anything below a substantial project size.

A transfer is a purchase and sale. It does not require admitting a partner, restructuring the ownership entity, or running partnership allocations for a decade. That collapse in complexity is what opened credit monetisation to project sizes that could never previously carry it — which is most energy projects sitting on commercial real estate.

How a transfer actually works

1. 01The project generates an eligible credit. Eligibility is credit-specific; the clean electricity investment and production credits are among the transferable ones.
2. 02The seller and an unrelated buyer agree terms — the amount of credit, the price as a percentage of face value, timing of payment, and the allocation of risk if the credit is later reduced or disallowed.
3. 03Diligence runs. The buyer examines the project's eligibility, cost basis, begin-construction and placed-in-service positions, compliance with wage, apprenticeship, and sourcing requirements where applicable, and the seller's own standing to make the transfer.
4. 04Risk is papered. This is where most of the negotiation sits: indemnities from a creditworthy party, and increasingly tax insurance covering recapture or disallowance risk.
5. 05The transfer is elected and reported. There are procedural registration and election requirements, and getting them wrong is not a curable technicality — treat the compliance steps as part of the deal, not administration afterwards.

What determines the price you get

Credits trade at a discount to face value. Rather than quote a price that will be stale, understand the drivers, because most of them are things you can improve.

• Size. Larger credits attract more buyers and better execution. Very small credits struggle to justify the transaction cost on either side.
• Credit quality and documentation. A project with clean, organised evidence of eligibility, cost basis, and construction timing prices better than an identical project with a disorganised file. This is the single most controllable factor.
• Indemnity strength. A buyer is pricing the risk that the credit gets reduced. An indemnity from a substantial, creditworthy entity — or tax insurance — narrows the discount.
• Timing certainty. Credits that are already earned and documented price differently from credits contingent on a project reaching completion on schedule.
• Whether wage, apprenticeship, domestic-content, and foreign-entity requirements are clearly satisfied. Ambiguity on any of these is priced as risk.

How the proceeds fit your capital stack

This is where the structure needs thought rather than assumption. Transfer proceeds usually arrive around or after the credit is earned, which is generally tied to placed-in-service — not at the start of construction when you need the money. That timing mismatch is a financing problem with a standard solution: a bridge facility against the anticipated transfer proceeds, sized against a contracted purchase agreement.

Getting that bridge requires the transfer agreement to be bankable — a creditworthy buyer, clear conditions, and a payment mechanic a lender can underwrite. Sponsors who leave the transfer to the end of the process often find they have a good credit and no way to convert it into construction-period liquidity. Line the transfer up early enough that it can be financed against.

The mistakes that cost real money

• Treating the credit as a certainty in the equity model. Until it is documented, diligenced, and contracted, it is a probable source, not a committed one. Size your equity accordingly.
• Assembling the documentation retroactively. Begin-construction and cost-basis evidence built after the fact is worth less to a buyer and prices worse. Build the file as the project proceeds.
• Ignoring the procedural requirements. Registration and election mechanics are not optional and not always forgiving.
• Negotiating price without negotiating indemnity scope. The headline percentage is less important than what you are on the hook for if the credit is later challenged. A better price with an unlimited, uncapped indemnity from your own balance sheet may be worse than a lower price with a capped one.
• Leaving the timing mismatch unaddressed until construction is underway.

Transferability is genuinely useful, and it has changed which energy projects on real estate are financeable. It rewards preparation more than negotiation: the sponsors who get good execution are the ones whose evidence file was built as the project went, not the ones who bargained hardest at the end.
