Tax equity is a financing structure that allows an investor with sufficient tax liability to invest in a qualified project and potentially receive federal tax credits, depreciation benefits, project cash flow, and other economic benefits.
In the solar industry, tax equity helps connect investors seeking tax-efficient opportunities with developers that need capital to build eligible solar and energy storage projects. Because these transactions involve complicated tax rules, project risks, and long-term agreements, investors should evaluate them with qualified tax, legal, and financial professionals.
What Is Tax Equity?
Tax equity refers to an investment in which a taxpayer provides capital to a qualifying project in exchange for an agreed allocation of tax benefits and other financial interests.
The project developer may be unable to use all the available tax benefits directly. A tax equity investor with an appropriate tax profile can provide part of the project’s required capital and potentially use the allocated benefits, subject to the transaction structure and applicable tax rules.
Tax equity is commonly associated with renewable energy, affordable housing, and historic rehabilitation projects. In solar project finance, the investor generally acquires an ownership interest in the entity holding the eligible solar assets.
What Is Solar Tax Equity?
Solar tax equity is a form of tax equity financing involving qualified solar or energy storage property. The investor contributes capital to a project or portfolio and receives an agreed share of potential tax credits, depreciation, cash distributions, and other economic benefits.
For qualifying clean electricity property placed in service after December 31, 2024, the federal Clean Electricity Investment Credit under Section 48E generally provides a base credit equal to 6% of qualified investment. The credit may increase to as much as 30% when applicable prevailing wage and apprenticeship requirements are met. Additional increases may be available for qualifying domestic content and energy community projects.
Credit availability and value depend on the project, placed-in-service date, labor compliance, equipment sourcing, location, ownership structure, and other requirements. Review the current IRS Clean Electricity Investment Credit guidance for additional information.
How Does Tax Equity Financing Work?
A typical solar tax equity transaction involves several participants:
- Project sponsor: Develops or manages the solar project and contributes part of the required capital.
- Tax equity investor: Contributes capital and receives an agreed allocation of tax benefits and project economics.
- Project entity: Owns the eligible solar assets and governs how benefits, responsibilities, and cash flow are allocated.
- Professional advisors: Tax professionals, attorneys, accountants, engineers, and other specialists evaluate the transaction and its compliance requirements.
Many traditional tax equity investments use a partnership structure. The sponsor and investor hold interests in a project entity, and the operating agreement determines how tax credits, depreciation, income, losses, and cash distributions are allocated.
The allocation may change after certain time, performance, or return conditions are satisfied. The sponsor may also have an option to acquire the investor’s remaining interest, subject to the governing agreements and applicable tax rules.
Tax Equity Investment Versus Transferable Tax Credits
Traditional tax equity and transferable tax credits are related, but they are not the same.
In a traditional tax equity investment, the investor generally acquires an ownership interest in the project entity. The investor may receive tax credits, depreciation, cash flow, and other economic benefits associated with that ownership.
A transferable tax credit transaction generally allows an eligible project owner to sell all or part of certain credits to an unrelated taxpayer for cash. The buyer does not necessarily acquire ownership of the underlying project and generally does not receive project depreciation or operating cash flow.
The IRS requires eligible transfers to follow specific election, registration, filing, and reporting rules. More information is available in the IRS guidance on transferable clean energy credits.
Potential Benefits of Solar Tax Equity
Depending on the transaction and investor, potential benefits may include:
- Federal clean energy investment tax credits
- Depreciation deductions allocated through the project structure
- Cash distributions generated by project operations
- Potentially attractive after-tax economics
- Exposure to operating renewable energy assets
- Support for domestic clean energy development
These benefits are not guaranteed. Their availability depends on the investor’s tax position, the project’s eligibility, proper documentation, the governing agreements, and continued compliance with federal tax requirements.
What Risks Should Investors Consider?
Solar tax equity investments are complex and may involve several important risks:
- Tax eligibility risk: The project may fail to satisfy requirements needed to support the anticipated credit.
- Recapture risk: Certain events during the applicable recapture period can reduce or reverse previously claimed tax benefits.
- Project performance risk: Energy production, operating costs, equipment performance, or customer payments may differ from projections.
- Liquidity risk: Ownership interests in project entities are generally not publicly traded and may be difficult to sell.
- Structural risk: The economic outcome depends heavily on the transaction documents and allocation provisions.
- Tax capacity risk: An investor may not be able to use the anticipated credits or deductions as expected.
- Regulatory risk: Tax rules, administrative guidance, and compliance interpretations can change.
Who May Be a Solar Tax Equity Investor?
Potential investors may include corporations, banks, insurance companies, family offices, trusts, partnerships, and certain qualified individual investors. Eligibility does not depend only on wealth or total tax liability. The nature of the investor’s income, passive activity rules, ownership structure, investment activity, and ability to accept project risk may all affect suitability.
Individuals face additional limitations that can materially affect their ability to use credits, deductions, and losses. Learn more in our guide, Who Qualifies as a Solar Tax Equity Investor?
How Investors Can Evaluate an Opportunity
A disciplined evaluation normally includes:
- Reviewing the investor’s current and projected tax position
- Confirming project eligibility and credit qualification
- Evaluating the project sponsor and operating counterparties
- Reviewing construction, equipment, insurance, and performance risks
- Analyzing projected tax benefits and cash distributions
- Reviewing the partnership and transaction documents
- Confirming reporting, compliance, and asset management responsibilities
- Stress testing the investment under less favorable assumptions
No investment should be evaluated solely on the advertised value of its tax credits. The underlying project, contractual obligations, transaction costs, and investor-specific tax treatment are equally important.
Is Solar Tax Equity Right for You?
Solar tax equity can provide qualified investors with access to clean energy projects and potentially valuable tax benefits. However, these investments are highly structured and are not appropriate for every taxpayer.
