The introduction of transferable clean energy tax credits under Section 6418 has created a new marketplace for monetizing the Investment Tax Credit (ITC). While this structure simplifies the sale and transfer of tax benefits, it has also introduced new risks for both buyers and sellers. To manage these risks, the market has developed a new tool: tax credit insurance, commonly referred to as ITC insurance when applied to Investment Tax Credit transactions.
ITC insurance protects the buyer from financial loss if the Internal Revenue Service (IRS) challenges the validity of a transferred tax credit and reduces or disallows its value. As the clean energy finance market matures, this form of insurance is becoming a key component of deal structuring, particularly for institutional investors and lenders who require independent, third-party risk mitigation.
Why Tax Credit Insurance Exists
In a typical tax credit transfer agreement (TCTA), the seller provides representations, warranties and indemnities confirming that the credits were properly generated, documented and remain eligible. However, when a project sponsor lacks strong credit or balance sheet capacity, the buyer may not be fully protected if the IRS later disputes the credit.
Tax credit insurance steps in to bridge that gap. It transfers specific IRS-related risks from the transaction counterparties to a highly rated insurance carrier. These policies are bespoke and can be structured to fit the project’s risk profile and financial exposure. In recent years, insurance coverage has become increasingly common in clean energy tax credit transactions, providing greater comfort to buyers and their financing partners.
What Risks These Policies Cover
Typical ITC insurance policies cover financial losses arising from:
- Eligibility and qualification risks such as failure to meet statutory or regulatory requirements.
- Basis risk if project costs used to calculate the credit were overstated or not properly supported.
- Recapture risk if the project is sold, destroyed or taken out of service within five years of being placed in service.
- Placed-in-service risk if the project fails to meet IRS timing rules for the applicable tax year.
- Adder and multiplier risk if the project does not qualify for bonus credits such as domestic content or prevailing wage.
Policies can be structured to cover all risks (“full-wrap” coverage) or targeted exposures such as recapture or basis risk. Many buyers prefer insurance even when sellers provide indemnities, particularly when dealing with smaller or non-investment-grade counterparties.
How ITC Insurance Works
An ITC insurance policy typically has a seven-year term, long enough to cover the five-year recapture period and the statute of limitations. Premiums usually range from 2% to 5% of the insured limit and are often paid by the seller as part of the transaction’s closing costs.
Coverage limits generally equal 100% to 140% of the face value of the transferred credits, providing room for potential interest, penalties and contest expenses. In the event the IRS disallows any portion of the credit, the insurer reimburses the buyer for the resulting financial loss, subject to policy terms and exclusions.
Policies are “claims-made,” meaning that reimbursement occurs only after a final IRS determination or court decision. Legal and accounting costs, known as contest costs, may be reimbursed earlier once the insured has spent through a defined retention amount.
Key Terms and Negotiation Points
Because each policy is customized, the specific wording matters. Buyers and their advisors should pay close attention to:
- Gross-up provisions that ensure insurance proceeds are not themselves taxable.
- Change-in-law clauses that exclude losses from future statutory or regulatory changes unless negotiated otherwise.
- Audit-control rights that determine who manages IRS disputes and how far appeals must go.
- Recapture exclusions that clarify which actions (such as voluntary sale) could void coverage.
Proper alignment between the insurance policy and the tax credit transfer agreement is essential. Early coordination between the buyer, seller, counsel and broker can help ensure both documents allocate risks consistently and avoid coverage gaps.
Who Benefits from ITC Insurance
ITC insurance provides value across several transaction types:
- Buyers gain protection from IRS challenges and enhanced confidence in credit quality.
- Sellers reduce contingent liabilities and make their credits more marketable.
- Lenders and tax equity investors gain comfort from an independent, investment-grade guarantor.
- Developers can execute transactions more efficiently by broadening the pool of eligible buyers.
In short, insurance enhances liquidity, improves pricing certainty, and builds trust in a rapidly evolving market for clean energy tax credits.
The Market Landscape
The ITC insurance market continues to evolve. Terms and coverage levels vary by technology, project size and counterparty strength. Larger utility-scale solar and storage projects often use full-wrap coverage, while smaller transactions may opt for partial coverage focused on specific risks.
Several independent analyses have tracked this evolution, including the Guide to the Tax Credit Insurance Market published by Crux Climate, which provides valuable insight into how insurers are structuring these products and where the market is heading.
While insurance cannot eliminate every risk, it converts potential tax exposure into a manageable, insurable event, helping accelerate capital deployment into the clean energy transition.
