A 30-install-a-month residential owner in Texas put it to us almost word for word: "I get the tax thing. §25D is gone, §48E is alive, prepaid leases are the new default. What I need to know is what it does to my cashflow when my distributor invoice is due and TPO funding is stuck because somebody on my crew forgot to photograph a serial number."
He's not the only one. We've talked to a lot of installers this quarter, and almost everyone gets the new tax landscape in the abstract. §25D (the residential homeowner credit) is gone, §48E (the commercial credit the lessor claims) is alive, and traditional TPO's and prepaid leases are how 60–65% of 2026 residential deals are getting done. What people are still working out is the messy part: how to explain it to customers without overpromising, what documentation it asks of the operations crew, and when the cash actually shows up.
In this post, we're walking you through both. First, the mechanics: how a $50,000 prepaid lease moves money around, who pays what when, and how the lessor actually makes a buck. Then we discuss the four risks that separate a healthy 2026 book of business from one that ends up with voided contracts and 1-star reviews.
How a prepaid solar lease actually works
The reason this product exists and is such a hot topic in 2026 is because of the OBBBA bill signed into law July 4, 2025. It killed the residential ITC §25D, the credit homeowners used to claim when they bought solar with cash or a loan effective January 1, 2026. The bill, however, left the commercial ITC, §48E alive through at least 2027. (Yes, there are safe-harbor rules that can extend that. We're not getting into those today. This is complicated enough.)
Translation: a homeowner who pays cash or finances with a loan in 2026 gets zero federal tax help. The same homeowner on a prepaid lease routes the credit through the lessor who claims §48E (30% base, plus up to 20% more if the system uses domestic content or sits in an "energy community"), plus MACRS depreciation (a tax shield the lessor sips from over five years). The lessor then prices part of that captured value back to the homeowner as a 20–30% discount on the upfront cost. To the homeowner, it feels like buying solar at a meaningful discount. However, legally and economically, they're entering a 25 year lease with an option to transfer ownership to them at year six.

Take a 12 kW PV system with battery with an all-in price of $4/W. That's a $50,000 project. A cash or loan homeowner pays $50,000 with no federal offset. The same homeowner on a prepaid lease pays roughly $35,000 upfront, about 70% of the price. The ~$15,000 gap is made up by the lessor using the value of the §48E + MACRS tax offsets.
Two pieces of mechanics actually matter to your business: when the cash moves, and how the lessor turns that captured tax value into a workable margin. To the homeowner this can feel like a cash deal. However, don't let the homeowner's experience confuse the operational reality. To you, every project is still a TPO lease: staged milestone payments, strict documentation at each step, and a final 30% that doesn't release until the funding audit clears.
Below is an example of the typical payment structure of a prepaid lease. The milestone payment parameters can vary slightly from lessor to lessor but will follow this typical pattern.
Who pays what, when
How the lessor makes money on the same system
The thing nobody pitches when they're recruiting you to push prepaid leases? That the 2026 TPO business is not a high-margin business. It's a high-volume, tax-arbitrage business. The lessor's $0–$7,500 of net profit per system is dwarfed by the $15,000 of §48E credit they're claiming on it. The credit is the engine. The lease is the legal vehicle that lets them claim it.
That structural reality is why a lessor is unlikely to release final funding when the documentation has gaps. For §48E projects, the lessor needs a defensible tax-credit file: FEOC-related attestations or supplier documentation where required, domestic-content substantiation if a domestic-content bonus is being claimed, and evidence that the installed equipment matches the procurement records, such as serial numbers, invoices, and install photos. Those records help support the project’s eligibility, credit basis, and any bonus-credit amounts if the IRS ever audits the claim. In practice, the funding packet is not just an operational checklist. It is part of the lessor’s audit defense. Your final payment depends on the lessor being confident that the project can stand up to review.
One more piece of mechanics matters. There’s the option for ownership of the PV system to transfer to the homeowner at the start of Year 6 once the five-year recapture period for the §48E Investment Tax Credit has concluded. This transition is governed by IRS "True Lease" principles, which ensure the arrangement is treated as a valid lease rather than a Disguised Sale. Two key regulatory pillars define this structure. First, to maintain the tax benefits of ownership, the lessor must retain a meaningful "at-risk" investment in the system; this is why prepaid leases often cap the upfront payment (frequently around 80%) to ensure the lessor maintains an ongoing economic interest. Second, under established tax law and Rev. Rul. 55-540, the buyout price must reflect Fair Market Value (FMV) as determined at the time of transfer. Contracts strictly avoid guaranteeing a "bargain" purchase price—such as $1 or a predetermined fixed dollar amount—as doing so would cause the IRS to reclassify the lease as an installment sale, potentially disqualifying the lessor's tax credits.
However, in practice, the sales pitch almost always implies a number. That gap between what the sales rep says at the kitchen table and what the contract actually allows is where two distinct risks live. Customer-facing: a homeowner who heard "free" gets a Year-6 letter with a fair market value (FMV) transfer amount they weren’t expecting and files a UDAAP complaint with the state attorney general. Federal-tax: if the pitch made the deal look like a sale rather than a lease, the IRS can recharacterize the whole arrangement as a disguised sale and chase the recapture back through the TPO master agreement to the installer who made the representation. More on this on Risk #2 and Risk #4.
Furthermore, prepaid leases do not reduce questions homeowners ask. They change the questions from “When will my system be installed?” to “Who owns the system?” “What happens in Year 6?” and “What if I sell my home?”
Now knowing the mechanics of prepaid leases, as an installer, what do you need to know in terms of its impact on your business?
Risk #1: Funding and operations are now the same workflow
A 60-install-a-month installer we talked to in Q1 was averaging Day 95 to final TPO funding. The fix wasn't bigger AR staff. It was the realization that their site capture, their procurement records, their install photos, and their funding packet were living in four different tools, and the documentation was being assembled manually at PTO from whatever the four tools had managed to capture along the way. Every gap between systems was where money got stuck.
That's milestone leakage. And in 2026 it's the single biggest determinant of whether you get paid on Day 75 or Day 120.
The fix is concrete. Drone-based site capture isn't optional anymore. Installers using it report first-submission approval north of 90%, and without it, you're running 2-to-4-week redesign cycles every time the site data is wrong. Domestic-content and FEOC capture has to happen at procurement, not retrofitted at PTO; the §48E adders depend on documentation the installer files away when materials arrive, and trying to reconstruct it at the funding-packet stage is where projects sit for an extra 30 days. Serial-number photography at install is now a funding requirement in most 2026 TPO contracts. Not a warranty nice-to-have. A funding requirement.
A unified CX platform where milestone communication and documentation capture sit in the same workflow amplifies the effect. When homeowners know what's happening at each milestone, they never become the bottleneck. Projects move quickly. Bodhi's published metrics show a 20% reduction in escalations against that posture.
Risk #2: The Year-6 conversation that prevents a 2032 lawsuit
Picture this. It's six years from now. A homeowner you sold a prepaid lease to in 2026 walks to her mailbox on a Tuesday and finds an envelope from her TPO. The letter says her system can transfer to her ownership for $4,200, not the "$0" or "basically free" her rep mentioned at the kitchen table back in '26. She calls you, not the TPO.
That envelope is the single biggest cancellation-and-lawsuit trigger in prepaid-lease programs. And it sits in sales' hands, not ops.
The issue isn't the dollar amount. It's a certainty gap. Reps describe an outcome, but the contract specifies a process. The homeowner discovers the difference six years later, when the letter arrives.
Here's why the contract has to read the way it does. The IRS structure forbids a preset transfer price. Rev. Proc. 2007-65 (the rule we mentioned earlier) requires the buyout to be FMV determined in good faith by the lessor. A contract guaranteeing $1 voids the §48E treatment the entire prepaid-lease product depends on. So no contract you'll ever see will guarantee a number, even though the marketing pitch implies one.
In well-structured contracts, the math at Year 6 could net to near-zero if the homeowner's residual prepaid-energy credit cancels out the appraised hardware residual. That's an empirical outcome and an outcome of a good-faith FMV appraisal six years from now, but cannot be a contract guarantee.
What lives underneath the certainty gap, and what most reps don't know, is the IRS Disguised Sale doctrine. This is the federal-tax doctrine under §7701, "substance over form" that lets the IRS look past the contract label "lease" and treat the whole arrangement as an installment sale, if the substance of the deal looks like a sale.
If they recharacterize a prepaid lease as a Disguised Sale, the §48E credit is voided and §50 recapture lands at 100% in Year 1, declining 20% per year through Year 5. That's about $15,000 per 12 kW system. And the lessor's master agreement with you, the one you signed when you became a TPO partner, almost certainly indemnifies the lessor against losses caused by your reps' representations. So that $15,000 chargeback per system flows down to you.
Three structural red flags determine which side a deal falls on:
- Red flag #1 — bargain purchase option. Transfer at less than FMV is the cleanest Disguised Sale signal there is. A rep saying "$1 at Year 6," even informally or verbally, is a recharacterization trigger. The IRS doesn't care whether it's in the contract. They can find the claim in the homeowner's reasonable expectation.
- Red flag #2 — lessor's skin in the game. The homeowner pays ~80% upfront, the lessor and tax-equity investor put in ~20%, and the lessor captures 30–40% of the system's value as stacked §48E + MACRS. The IRS can argue that what the homeowner actually rented was the lessor's ability to claim tax credits, not a solar system.
- Red flag #3 — the 6-year timing. Year 6 lines up exactly with the close of the §50 recapture window. The IRS can scrutinize a transfer pegged to that boundary as engineered convenience and as evidence the parties always intended a sale and just dressed it as a lease for the credit.
Disguised Sale is the federal-tax counterpart to state UDAAP enforcement. UDAAP turns rep statements into voidable contracts. Disguised Sale turns the same statements into chargebacks the IRS can pursue against the lessor and, through indemnification, against you.

Risk #3: One financing partner is two too few
Sunnova filed Chapter 11 on a Wednesday morning in June 2025. 500,000 customers. $8.9 billion in debt. Years of accumulated brand, a working monitoring portal, a warranty book — all suddenly orphaned. The installers who'd built their books on Sunnova found out on the same conference call the homeowners did.
It wasn't an isolated event. SunPower in 2024. Posigen in 2025. Mosaic in 2025. The pattern isn't coincidental.
Most residential TPOs in 2026 are securitization-dependent monolines. Translation: they fund themselves by pooling their lease portfolio and selling asset-backed bonds to institutional investors. When ABS markets tighten — which is what happened in 2024 and 2025 — the monoline model breaks. It doesn't fail company-by-company. It fails structurally.
What works in 2026 is diversification. Two or three financing partners, not one. At least one of them should be a bank-backed originator whose capital is backed by bank deposits, not ABS-dependent. Climate First Bank with over $1 billion in assets, 9,000+ loans, $222.7 million originated is what that kind of capital stack looks like.

Risk #4: The compliance checklist most installers still aren't running
Three states wrote your 2026 sales script for you. Most installers are still using their 2025 pitch deck.
In Texas, SB 398/1697 makes contracts missing equipment and fee disclosures voidable, and requires salespeople to be registered with TDLR. In California, SB 784 requires a Pre-Loan Consumer Call and a signed Solar Consumer Protection Guide before contract execution. In Arizona, SB 1419 requires a licensed-contractor roof-serviceability report. If your reps are still working from 2025 materials and your contracts don't include state-specific disclosures, your 2026 deals are voidable. State enforcement is going to surface this year.
UCC-1 fixture filings are the home-sale landmine nobody mentions at the kitchen table. Every prepaid lease is secured by a UCC-1 against the equipment, which is a public filing on the property. Title companies find them at closing. Clearing or transferring one adds 2 to 4 weeks to the close and $200–$500 in legal and title fees. The homeowner finds out on a Friday. The 1-star review lands the next Wednesday.
Underneath all of it is the IRS Disguised Sale doctrine we walked through in Risk #2. Any prepaid-lease program where reps promise outcomes the contract doesn't match — "basically $1 at the end," "you'll own it outright," "nothing to clear when you sell" — runs a recharacterization risk that doesn't land on the financier. It lands on you, through indemnification in the master agreement.
The federal-tax mirror image of state UDAAP enforcement reads the same factual record state regulators do — rep statements, marketing, kitchen-table claims — and asks the same question: did the homeowner lease a system, or rent the lessor's ability to claim tax credits? Sloppy sale rep conduct lets the IRS argue the second answer. The chargeback flows to whoever made the representation.
What installers are doing differently
The installers winning this year are doing four things at once, all of which are no longer optional.
- A unified CX platform that makes milestone communication and documentation capture the same workflow.
- Three financing partners, at least one of them bank-backed.
- Procurement that captures domestic-content and FEOC substantiation at receipt — not at funding-packet assembly.
- Written disclosure playbooks on FMV, dealer fees, home sale, and Year-6 ownership, so the Year-6 conversation isn't rep-by-rep improvisation.
If these four risks are what your team is dealing with, schedule a Bodhi+OneEthos partner call — Bodhi's CX platform plus no-dealer-fee loans through OneEthos is the operational and financial stack built for exactly this environment.
