Selling tax credits: Best tips to make them transactable

May 1, 2025

‍The market for transferable tax credits has taken off, catalyzing billions of dollars of investment into domestic energy and manufacturing projects. Prior to transferability, the only way for developers to monetize their tax credits was through complex tax equity partnerships with large financial institutions. Transferability has made the market more accessible to a wider range of developers and manufacturers, especially for smaller developers and newly eligible technology types.

Transferability has also widened the pool of taxpayers that can purchase tax credits. While tax equity partnerships are typically offered by a small group of large banks, transferability expands the market of potential tax credit buyers to any corporate taxpayers. 

A wider market — on both the sell side and the buy side — means increased competition. Sellers must find ways to make their tax credits stand out. 

This guide explores best practices that project developers and manufacturers can utilize to make their credits more appealing, ultimately generating more bids and maximizing the value of the credits.

Selling tax credits: FAQs

What are transferable tax credits?

The Inflation Reduction Act, passed in 2022, permits certain federal clean energy and manufacturing tax credits to be sold for cash, creating a more efficient way to deploy and recycle capital. Buyers earn a discount on the credits, reducing their tax liability and making participation in clean energy finance more appealing.

For projects that start construction after 2024, these tax credits come in the form of the §48E clean electricity investment tax credit (ITC) and the §45Y clean electricity production tax credit (PTC), which have replaced the traditional ITC and PTC framework. The §48E and §45Y credits are also referred to as the tech-neutral tax credits.

ITCs are one-time credits based on a percentage of capital investment in a project, while PTCs are per-unit credits based on the amount of energy produced by a renewable energy project or the number of components manufactured over a specific period. 

Projects that qualify for the tech-neutral tax credits include:

§48E-eligible projects

  • Solar energy systems
  • Wind energy systems (onshore and offshore)
  • Energy storage systems
  • Geothermal energy systems
  • Combined heat and power facilities
  • Landfill gas or renewable natural gas (new fuel source, for electric generation)
  • Municipal waste (new fuel source, for electric generation)
  • Nuclear facilities (new or repowered)
  • Hydroelectric
  • Zero-emission combustion and gasification facilities

§45Y-eligible projects

  • Wind energy facilities (onshore and offshore)
  • Hydroelectric
  • Landfill gas (for electricity generation)
  • Solar
  • Geothermal (for electricity generation)
  • Energy storage
  • Combined heat and power/waste energy recovery
  • Nuclear facilities (new or repowered)
  • Zero-emission combustion and gasification facilities

What are the benefits of selling tax credits?

Selling tax credits offers numerous advantages to tax credit sellers. From the seller’s perspective, participating in this market can:

  • Provide liquidity by converting non-liquid tax incentives to cash.
  • Reduce debt with mutually beneficial partnerships.
  • Support additional investments in clean energy and domestic manufacturing. 
  • Help form strategic partnerships with buyers and intermediaries. 

What factors affect tax credit value?

A range of factors can affect deal pricing for transferable tax credits, including:

  • Deal size: Larger deals usually have a higher market value because they often indicate a larger sponsor and so correlate with higher credit quality, experience, and strength of indemnities.
  • Tax credit type: The type of tax credit (ITC or PTC) and technology can influence the credit’s value based on current demand. 
  • Available supply: Pricing for individual tax credits is also shaped by the total supply of the credits available for purchase.
  • Buyer preference: Buyers may prioritize certain types of credits based on their own personal goals, niches, and preferences, which affects the credit’s liquidity. 
  • External conditions: Economic factors, policy changes, and regulatory updates can all impact the overall demand for tax credits and their value.

Because due diligence and risk mitigation are the most common causes of transaction delays, Crux recommends that tax credit sellers prepare the due diligence items that our data indicate are most likely to streamline a deal. Compile documentation across the following categories:

Eligibility and qualification

  • Which tax credit section are you eligible for? 
  • Do you qualify for a bonus adder(s)? Does the project qualify for a safe harbor?
    • Does your project qualify for the prevailing wage and apprenticeship (PWA) bonus adder?
    • What is your project’s placed-in-service date?
    • What is the seller counsel’s legal opinion?

Basis/excessive transfer risk

  • Did the seller calculate the project’s cost basis correctly? 
  • Is it well-defended by an appraisal?

Recapture

  • How will the seller mitigate the risk of recapture? Although Crux’s data indicates that recapture is exceedingly rare (occurring in 0.5% of historical tax credits and tax equity transactions), buyers prioritize mitigating this risk. ‘

Crux surveyed 35 of the leading law firms, insurers, tax advisors, and financial institutions in the market to identify the essential due diligence items for a transferable tax credit transaction. Learn more in our risk mitigation and due diligence whitepaper

3. Price appropriately

Competitive pricing benefits both buyers and sellers. Buyers seek competitively priced credits to manage their tax liability and maximize return on investment. Seventy percent of buyers and advisors say they optimize for price when selecting which credits to bid on. Sellers have a higher chance of transacting when the deal is competitive.

As discussed above, deal size is an important driver of pricing for both ITCs and PTCs. Pricing tends to vary most across small deals, as recapture and basis risk, relevant mainly to ITCs, has an outsized role in small credit pricing in a market segment where insurance is difficult or not economically viable to procure.

Crux uses various pricing factors to support a transparent market price estimate, including taking in feedback from sellers. Crux equips all sides of the market with regularly updated price estimates, called the Cruxtimate, for each credit based on data from more than $30 billion in tax credit transactions. 

These estimates allow buyers and sellers to align on realistic pricing expectations and drive both parties toward a deal efficiently. Running a wide, transparent process allows sellers to optimize their tax credit transfers across price, timing, and other negotiated terms.
