Section 6418 of the Internal Revenue Code, introduced by the Inflation Reduction Act of 2022, establishes a framework for the transferability of certain federal tax credits—primarily focused on clean energy. This mechanism enables eligible taxpayers to transfer all or a portion of specified clean energy tax credits to unrelated taxpayers for cash, rather than using the credits to offset their own federal income tax liability.

Eligible Taxpayers and Credits

Eligible Taxpayers:

Any taxpayer subject to federal income tax, excluding tax-exempt organizations, state and local governments, Indian Tribal governments, Alaska Native Corporations, rural electric cooperatives, and the Tennessee Valley Authority. These excluded entities may instead benefit from the direct pay mechanism under Section 6417.

Eligible Credits (as of 2024):

30C

Alternative fuel vehicle refueling property credit

45

Renewable electricity production credit

45Q

Carbon oxide sequestration credit

45U

Zero-emission nuclear power production credit

45V

Clean hydrogen production credit

45X

Advanced manufacturing production credit

45Y

Clean electricity production credit

45Z

Clean fuel production credit

48

Energy investment tax credit

48C

Qualifying advanced energy project credit

48E

Clean electricity investment credit

Transfer Mechanics and Regulatory Requirements

Election Process

Made on original tax return for the year the credit is determined, by the due date (including extensions). The election is irrevocable and can only be made once per credit.

Payment Requirements

The transferee (buyer) must pay cash for the transferred credits. The payment is not includable in the transferor's gross income and is not deductible by the transferee.

IRS Pre-Filing Registration

A pre-filing registration process with the IRS is required before making the transfer election, ensuring compliance and tracking of credit transfers.

Recapture and Compliance

The transferee (buyer) is generally responsible for recapture. Final regulations clarify allocation of recapture when only part of a credit is transferred.

Treatment of Partnerships and S Corporations:

Partnerships and S corporations may make the transfer election for credit property they hold directly. The proceeds are treated as tax-exempt income and allocated to partners or shareholders according to their distributive share.

Key Regulatory Updates

The IRS and Treasury finalized rules on April 25, 2024, clarifying definitions, transfer mechanics, documentation, anti-abuse provisions, and compliance requirements.

Key Updates Include:

Clarification of "credit property" definition and how credits can be transferred
Establishment of a pre-filing registration process through the IRS
Detailed requirements for the transfer election statement
Anti-abuse rules to prevent transfers made primarily for tax avoidance
Limited correction relief for certain errors in transfer elections

OB3 Legislative Changes OB3 Update

Overview: One Big Beautiful Bill (OB3) Impact on Section 6418

The One Big Beautiful Bill Act (OB3) introduces significant modifications to the IRA's clean energy tax credit framework. While Section 6418 transferability remains intact, several credits eligible for transfer face accelerated sunsets, tightened eligibility requirements, and new restrictions. Market participants should carefully evaluate how these changes affect both new origination and existing transfer agreements.

Credits Affected by OB3 Changes

30D

Clean Vehicle Credit

Immediate Changes

OB3 imposes immediate Foreign Entity of Concern (FEOC) restrictions on battery components and critical minerals sourcing. Vehicles containing any battery components manufactured or assembled by an FEOC, or critical minerals extracted, processed, or recycled by an FEOC, become ineligible for the credit. This significantly narrows the pool of qualifying vehicles and impacts the transferability pipeline for dealer-based credit transfers.

45Y

Clean Electricity Production Credit

Accelerated Sunset

OB3 accelerates the sunset for the technology-neutral clean electricity production credit (45Y). Rather than phasing down based on emissions targets, the credit faces a fixed termination date. Projects that have not begun construction by the applicable deadline will not qualify. This change compresses the origination window for new renewable generation projects seeking to transfer PTCs.

48E

Clean Electricity Investment Credit

Accelerated Sunset

Mirroring the 45Y changes, the technology-neutral clean electricity ITC (48E) faces an accelerated sunset. The credit will no longer be available for projects that fail to meet the begun-construction safe harbor before the new cutoff. Developers relying on 48E for solar, storage, and other clean electricity facilities should evaluate whether their projects can meet the revised timeline.

45X

Advanced Manufacturing Production Credit

Rate Reductions

OB3 introduces potential rate reductions for certain 45X-eligible components. Manufacturers of solar cells, wafers, polysilicon, battery cells, and other qualifying components may see reduced per-unit credit amounts in future years. Transfer pricing for 45X credits will need to account for these declining rates when structuring multi-year agreements.

45V

Clean Hydrogen Production Credit

Modified Eligibility

OB3 modifies the eligibility requirements for the clean hydrogen production credit. Changes to lifecycle emissions accounting methodology and the "three pillars" framework (incrementality, temporal matching, deliverability) may alter which production pathways qualify and at what tier. Hydrogen producers and their transfer counterparties should reassess credit amount projections under the revised rules.

Transition Rules and Begun-Construction Safe Harbors

OB3 preserves begun-construction safe harbors for projects that demonstrate meaningful progress before the applicable cutoff dates. Two established methods remain available:

Physical Work Test

Significant physical work of a proper nature must begin on the project before the cutoff date. Work must be performed at the project site or on custom-manufactured components.

Five Percent Safe Harbor

The taxpayer must incur at least five percent of the total cost of the project before the cutoff date. Continuous efforts (continuity safe harbor) must be maintained thereafter.

Projects meeting the begun-construction threshold before the OB3 effective dates generally remain eligible under prior-law credit terms. The continuity requirement (typically a four-year window to place in service) still applies. Developers should carefully document their construction-start activities to preserve safe harbor protection.

Foreign Entity of Concern (FEOC) Restrictions

OB3 Update

OB3 expands and accelerates FEOC restrictions across multiple credit types. These rules disqualify credits where key components, materials, or inputs are sourced from designated foreign entities of concern (primarily entities connected to China, Russia, North Korea, and Iran).

Clean vehicle credits (30D) face immediate FEOC battery component and critical mineral restrictions
FEOC sourcing limitations may extend to solar cells, inverters, and battery storage components under 48E and 45X
Transfer buyers should require FEOC compliance representations and warranties in all transfer agreements
Supply chain documentation and attestation requirements are expected to increase significantly

Impact on Existing Transfer Agreements and Pipeline Deals

Executed Agreements

Existing transfer agreements for credits already placed in service generally remain valid. However, parties should review change-of-law provisions and indemnification clauses.

Pipeline Deals

Deals in negotiation should be reassessed for credit availability under OB3 timelines. Pricing, representations, and closing conditions may need updating.

Multi-Year Commitments

Forward commitments for production credits (45, 45Y, 45X) should include OB3-specific contingencies and repricing mechanisms tied to legislative changes.

Due Diligence Updates

Buyer diligence checklists should be updated to include FEOC compliance verification, begun-construction documentation, and OB3 sunset date analysis.

Key IRS Notices and Guidance to Monitor

As OB3 provisions take effect, the IRS and Treasury are expected to issue implementing guidance. Market participants should monitor the following:

Updated IRS pre-filing registration guidance reflecting OB3 credit modifications
Treasury regulations or notices clarifying FEOC definitions and compliance procedures
Begun-construction safe harbor notices with OB3-specific cutoff dates
Revised Form 3800 instructions and transfer election statement requirements
Guidance on transition rules for credits with modified rates (45X) or eligibility criteria (45V)
IRS FAQ updates addressing OB3 impacts on pending and future transfer elections

Step-by-Step Transfer Process

1

Identify Eligible Project

Find and pursue a project eligible for transferable tax credits.
2

Satisfy Credit Requirements

Complete all requirements to earn the eligible credit (e.g., place the project in service).
3

Complete IRS Registration

Complete the electronic pre-filing registration and obtain a registration number for each credit property.
4

Arrange Transfer

Arrange the transfer to an unrelated party for cash.
5

Provide Documentation

Provide the transferee with the registration number and required documentation.
6

Complete Election Statement

Complete and sign a transfer election statement with the transferee.
7

File Tax Return

File a timely tax return with the transfer election statement and all required attachments.
8

Transferee Filing

The transferee must also file a timely return with the statement to claim the credit.

Documentation and Compliance

Proper documentation is critical for successful tax credit transfers. Both the transferor and transferee must maintain comprehensive records to substantiate the credit's validity and the transfer's compliance with regulations.

The transferor must provide the transferee with "required minimum documentation" validating the credit's existence and eligibility.

Required Documentation Should Include:

Credit Eligibility and Validation

Documents proving the credit's qualifications and statutory compliance

Bonus Credits Substantiation

Evidence supporting claims for increased credit rates

Qualifying Costs or Activities

Documentation of eligible costs or production activities

Special Requirements Compliance

Evidence of compliance with requirements like prevailing wage and apprenticeship

This documentation serves as protection for the transferee in case of IRS audit or examination, providing evidence of the credit's validity and proper transfer procedures.

Timing Considerations

Timing is critical for tax credit transfers. Careful planning is essential to meet all deadlines and properly execute the transfer.

Key Timing Requirements

Original Tax Return Only

The transfer election must be made on the original tax return for the year the credit is determined
No Amended Returns

Elections cannot be made on amended returns
Pre-Filing Registration First

Pre-filing registration with the IRS must be completed before making the transfer election
Both Parties Must File

Both parties must include the transfer election statement on their respective timely filed returns

Planning ahead is essential to ensure all deadlines are met and the transfer is properly executed. Missing any timing requirement could invalidate the transfer.
