Portfolio §48E credit deals: buying credits from more than one project

Some §48E sellers and brokers offer credits from several solar, storage or other qualified facilities in one deal, sometimes from more than one sponsor. A portfolio can spread facility-level risk and fill a larger tax appetite. But the tax rules still work one property at a time, so the paperwork, diligence and risk allocation have to as well.

The rules work property by property

Rule	What it means in a portfolio	Source
Eligible credit property	For §48E, each qualified facility (or each energy storage technology) is its own eligible credit property.	Treas. Reg. §1.6418-1(d)(11)
Registration	The seller must obtain a registration number for each property before the election, and the number goes on the return.	Treas. Reg. §1.6418-4; IRS transferability FAQs
One election per property	A transfer election is made for a specified credit portion of a single eligible credit property. Two facilities need two elections.	Treas. Reg. §1.6418-2(b)(1)
Pro rata bonus amounts	A specified credit portion must carry a proportionate share of each bonus credit amount. A buyer cannot take only the base credit or only the bonus portion of one facility.	Treas. Reg. §1.6418-1(h)
Excessive transfer and recapture	Measured per property. All buyers of one property are treated as one transferee for the excessive credit test.	Treas. Reg. §1.6418-5(b)(2), (d)
No resale	A purchased portion cannot be transferred again, so the portfolio cannot be repackaged by the buyer.	Treas. Reg. §1.6418-2(c)(2)

Timing: different facilities, different years

A §48E credit is generally determined for the year the facility is placed in service. Under §6418(d), you take a credit into account in your first taxable year ending with or after the seller's taxable year in which the credit was determined. A portfolio whose facilities come online on different dates can therefore deliver credits in different tax years. Payment must also meet the paid-in-cash window for each credit (Treas. Reg. §1.6418-1(f)). Match each tranche to the right tax year and your estimated payments. See estimated tax with transferable credits.

Questions to ask the seller or broker

• Schedule of facilities: location, technology, size, expected placed-in-service date, registration status and expected credit, including each bonus amount, for every facility.
• Substitution and shortfall: if one facility slips a year or comes in smaller, can the seller substitute another facility, and on what price and diligence terms? Or does the purchase amount simply shrink?
• Separate or blended pricing: is each facility priced on its own, or at one blended price? Bonus-heavy or later-dated tranches may deserve different terms. See §48E pricing.
• Indemnity and insurance by facility: do the indemnity cap and insurance limit apply per facility or across the pool, and does one facility's loss use up protection for the others? See indemnity and insurance terms.
• Multiple sponsors: if facilities come from different sellers, are there separate agreements, indemnitors and guarantors?
• Wind and solar start dates: for each wind or solar facility, how did construction begin, and by when must it be placed in service? See solar and wind deadlines.
• Foreign-entity rules: prohibited foreign entity and material assistance diligence for each facility. See foreign-entity rules.

Benefits and trade-offs

Potential benefit	Trade-off
A problem at one facility affects only part of the credit.	More diligence: each facility needs its own cost basis, bonus and placed-in-service evidence.
Can fill a larger tax appetite in one negotiation.	More elections, statements and return lines to track. Your CPA reports each registration number on Form 3800.
Tranches can be scheduled across tax years.	A facility delay can move credit into a year you did not plan for.

What to be careful of

• "Portfolio" is a commercial label, not a tax concept. The IRS sees separate elections for separate properties.
• Keep a facility-level file with the registration number, election statement, cost and bonus support, and the recapture notice contacts. You will need it for five years.
• Run your §38(c) capacity for each tax year a tranche lands in, not just the total. For very large buyers, also see CAMT and purchased credits.
