Solar projects often generate federal tax attributes that developers cannot use efficiently. Tax equity connects the project with an investor able to use those benefits. In exchange for cash, the investor receives an agreed share of tax credits, depreciation, distributions and partnership economics.
For eligible property placed in service after 2024, the technology-neutral Section 48E credit generally replaces the legacy Section 48 energy credit. The IRS describes a 6 percent base credit that can increase to 30 percent
when prevailing-wage and apprenticeship requirements are satisfied, with potential bonuses. The rules must be confirmed for each project.
Important distinction:
tax equity is not simply a loan secured by future tax credits. A traditional tax-equity investor receives an ownership interest and negotiated tax allocations. A tax-credit buyer purchases the credit without taking project ownership.

How the partnership flip works
Common structure
Investor economics before and after the flip
The sponsor and investor become partners in the project company. The investor contributes capital and initially receives most tax benefits plus a negotiated share of cash. After reaching an agreed yield or date, the allocations flip, leaving the sponsor with most long-term economics.
The sponsor may later have an option to purchase the investor's remaining interest at fair market value. Other structures include sale-leasebacks and inverted leases. Project size, timing, sponsor objectives and lender requirements determine the appropriate structure.
Tax equity versus selling the credit
Section 6418 transferability gives eligible taxpayers another monetization route. A project owner can sell all or part of an eligible credit to an unrelated buyer for cash. Under the IRS transferability process, the project must satisfy credit requirements, complete pre-filing registration, obtain a registration number, execute a transfer-election statement and report the election on a timely return.
A credit buyer receives neither project ownership nor depreciation. Traditional tax equity can monetize both credits and depreciation, but requires deeper diligence and more complex documentation. Developers can compare Financely's explanations of commercial solar tax-credit transferability

How a tax-equity transaction reaches closing
1. Confirm eligibility
Tax counsel identifies the credit, eligible basis, placed-in-service timing, wage requirements, bonuses and current sourcing restrictions.
2. Model the economics
The sponsor compares tax equity, credit transfer and bridge structures against dilution, timing, cost and retained cash.
3. Prepare diligence
Investors review ownership, site control, interconnection, permits, revenue assumptions, EPC contracts, insurance and engineering.
4. Negotiate documents
The parties settle funding conditions, tax allocations, indemnities, recapture protection, governance, distributions and exit rights.
5. Fund the investment
Capital may arrive in installments linked to construction completion and placed-in-service milestones.
6. Maintain compliance
The partnership preserves tax, accounting and operational records throughout the investment period.
Recapture risk:
investment-credit recapture may arise during the statutory recapture period if ownership or qualifying use changes. Investors therefore require representations, sponsor indemnities, reporting covenants and controlled-transfer provisions.

Baker Botts
For legal and federal tax structuring, Baker Botts' Houston renewable-energy tax team
is a credible Texas option. Its publicly stated experience includes representing solar and wind developers in tax-equity financings and tax-credit transfers.
We recommend considering the firm when a transaction needs specialist tax counsel, partnership documentation and coordination with project-finance lawyers. Sponsors should still compare scope, conflicts, staffing and fees before appointment.
The sponsor also needs a defensible model, investor materials and coordinated capital strategy. Financely's utility-scale solar financing overview
explains how debt, sponsor equity and tax equity fit together.
Frequently asked questions
Does a tax-equity investor lend money?
No. In a traditional structure, the investor purchases an ownership interest and receives negotiated tax and cash allocations. A bridge lender provides debt instead.
Can a project claim both the investment and production credit?
No. The same facility cannot claim both credits. Tax counsel should confirm the choice after both alternatives have been tested in the financial model.
