ITC vs. PTC Pricing in 2026: Why the Discount Gap Is Widening

Investment tax credits (ITCs) and production tax credits (PTCs) have always priced differently in the transferable credit market. PTCs clear at a higher percentage of face value. That’s been true for years, and most experienced buyers understand the basic reason: PTCs carry no recapture risk, and the underlying production data is straightforward to verify. ITCs require more work: five-year recapture exposure, cost basis substantiation, and placed-in-service documentation. Buyers get paid for that work through a larger discount.

What’s changed in 2026 is the size of the gap. Three things have pushed it wider: the One Big Beautiful Bill Act (OBBBA), the new Foreign Entity of Concern (FEOC) framework, and the accelerated phase-out of solar and wind credits. None of these hit PTCs and ITCs equally. So while the diligence burden on ITCs has grown, the burden on PTCs, comparatively, has not.

The Structural Difference, For Anyone Who Needs the Refresher

ITC recapture rules require the underlying project to remain in service for five years. If the project is sold, foreclosed, or taken out of service during that window, a portion of the credit is clawed back. PTCs don’t work that way; they reflect energy that has already been produced and delivered, which is metered and verifiable. There’s nothing to recapture because the credit was earned in real time.

Cost basis is the other issue. ITCs are calculated as a percentage of eligible project costs, and the IRS can dispute what qualifies. We’ve seen transactions where basis disputes surfaced years after closing, long after the buyer thought the deal was done. PTCs don’t have that exposure. The production records are what they are.

Neither of these is new. What OBBBA has done is add a third layer on top.

The FEOC Tail Is the New Diligence Problem

The FEOC framework requires both ITC and PTC projects to document that material assistance from prohibited foreign entities falls below the Material Assistance Cost Ratio threshold. The supplier documentation process is essentially the same for both credit types, so that piece is symmetric.

The asymmetry is what happens after placed-in-service. ITC projects carry a 10-year forward-looking FEOC recapture period. If the project enters into a contract during that decade that gives a prohibited foreign entity effective control, the full credit can be recaptured. PTC projects don’t carry that tail — each year’s credits are evaluated independently on that year’s production and FEOC compliance. The next year starts clean.

For buyers, a 10-year recapture tail on FEOC is a real indemnity item. It must be priced in. PTCs don’t require it.

Supply Dynamics Are Adding Pressure Too

Solar and wind ITC supply is now concentrated in projects that either established beginning of construction by July 4, 2026 or reach placed-in-service by December 31, 2027. That’s a defined and finite pool. Buyers know the bulk of it will come to market over the next two to three years, and some of them are factoring that supply concentration into their bids. Storage ITCs phase down more slowly through 2033, but storage projects carry their own complexity, including a higher 55% MACR threshold that creates its own diligence burden.

On the demand side, industry conversations in early 2026 have reflected genuine softening in ITC appetite among some large corporate buyers. A few have shifted preference toward PTCs or alternative credits like 45Z and 45X, which carry no recapture risk and no cost basis issues. That preference shift is showing up in pricing.

What This Means If You’re Selling ITCs

The widening gap doesn’t change the strategy, but it does sharpen what matters. Buyers are asking harder diligence questions in 2026 transfer agreements, and the sellers getting the best pricing are the ones who show up with complete documentation packages rather than assembling them reactively during diligence. Cost basis support, placed-in-service evidence, FEOC compliance documentation, and a clear answer on the 10-year recapture tail: all of it, before the buyer asks.

Tax credit insurance helps, but the math varies. The premium and deal fees need to be weighed against the actual pricing improvement the coverage delivers. That calculation isn’t the same on every deal.

What This Means If You’re Buying

A deeper ITC discount is also a better deal for buyers who can absorb the documentation and recapture exposure. The buyers getting the most out of the current market are evaluating ITC opportunities on a project-by-project basis rather than making categorical decisions about the credit type. A well-documented ITC with insurance in place and a developer who knows what they’re doing can outperform a PTC on a pure savings-per-dollar basis.

PTCs are the simpler purchase: faster closes, fewer moving parts. But solar and wind PTCs are now competing against 45Z and 45X for the same corporate tax capacity, and relative value depends on what else is in the market in a given quarter. Simpler isn’t always better.

A Note on How We Work

Fallbrook has been in the tax credit market for nearly four decades. I’ve been doing this for many years. The honest observation at this point in 2026 is that the market is more complicated than it was two years ago, and the transactions that close well are the ones where both sides understood what they were buying and selling before the transfer agreement was drafted.

If you’re buying or placing ITCs or PTCs this year and want a read on where pricing is and what buyers are actually asking for in diligence, I’m happy to have that conversation.
