Seller Financing & Seller Notes Under the New SBA Rules (2026 Guide)
Reviewed by the Regalis Capital acquisitions team. Last updated June 2026.
Seller financing is the seller agreeing to get paid over time instead of all at closing. In a small business acquisition, that promise is written up as a seller note, and the vast majority of Main Street deals include one. What changed in 2025 is not whether sellers carry paper, but how the SBA treats that paper when it counts toward your down payment. Get the structure wrong and a note you were counting on as equity becomes worth zero in the lender's eyes. This guide walks through exactly how seller notes work under the current rules.
How Does Seller Financing Work When Buying a Business in 2026?
Most small business sales still include some form of seller financing, where the seller carries a portion of the price as a note instead of taking all cash at closing. In a typical SBA 7(a) acquisition, the SBA 7(a) loan funds the bulk of the purchase, the buyer puts in cash, and a seller note can fill part of the gap.
Seller financing is the seller accepting deferred payment for part of the purchase price, documented as a promissory note (the seller note). In an SBA deal, the SBA 7(a) loan covers most of the price, the buyer contributes the required cash injection, and a seller note can cover up to half of that injection, but only if the note is structured on full standby. The note ranks behind the SBA loan, so the seller gets paid only after the lender does.
The seller note does two jobs. It bridges the gap between what the lender will finance and the agreed price, and it keeps the seller financially tied to the deal, which signals confidence that the business will perform after the handoff. A seller willing to carry paper is, in effect, betting on the business they just sold. That alignment is part of why lenders and buyers value a seller note, beyond the cash it saves at closing.
What Changed Under the June 2025 SBA Rules?
The biggest change is the standby term. Under SBA SOP 50 10 8 (effective June 1, 2025), a seller note only counts toward the buyer's equity injection if it is on full standby for the life of the SBA loan, not for a fixed 24 months. The old rule, where a seller note on standby for 24 months could count as equity, is obsolete. Do not rely on it, and be wary of any source still quoting it.
The obsolete pre-SOP rule said a seller note on standby for 24 months could count toward the buyer's equity injection. That is wrong under the current SOP. The rule now is full standby for the entire life of the SBA loan, which typically means 10 years of no principal and no interest paid to the seller. A note that goes off standby before the SBA loan is paid off does not count as equity.
This matters because buyers and even some brokers still plan deals around the old 24-month assumption. A buyer who structures a note to start paying the seller in year three thinks they have covered part of their injection. Under the current SOP, that note is not on full standby for the life of the loan, so the lender gives it zero equity credit, and the buyer is suddenly short on the down payment weeks before closing. The table below contrasts the obsolete rule with the current one.
| Treatment | Obsolete pre-SOP rule (do not use) | Current rule under SOP 50 10 8 |
|---|---|---|
| Standby term required | 24 months | Full life of the SBA loan (typically 10 years) |
| Payments allowed during standby | None for 24 months, then payments resume | No principal and no interest for the entire term |
| Counts toward equity injection | Yes, on a 24-month standby | Only on full standby for the life of the loan |
| Maximum equity credit | Varied | 50% of the required injection (5% of a 10% requirement) |
| If the note comes off standby early | Could still count | Counts as zero equity |
Comparison of the obsolete 24-month seller-note standby rule against the current full-standby-for-life rule (SBA SOP 50 10 8, effective June 1, 2025).
What Is Full Standby Versus Partial Standby?
Full standby means the seller receives no principal and no interest for the entire term of the SBA loan, typically 10 years. Partial standby, where the seller still collects interest or some payments during the standby period, does not qualify the note as equity under SBA SOP 50 10 8 (effective June 1, 2025). The distinction is the whole game.
Full standby is what the SBA requires for a seller note to count toward the buyer's equity injection. The seller agrees to sit completely silent on the note: no checks, not even interest-only payments, until the SBA loan is fully paid. Interest can accrue on paper, but nothing is paid out during the standby period. Only a note structured this way earns equity credit.
Partial standby is anything less. If the seller collects interest each month, or principal kicks in after a few years while the SBA loan is still outstanding, the note is on partial standby. Partial standby notes are common and perfectly legal, but they do not count as equity. They are simply additional subordinate debt behind the SBA loan, not part of the buyer's injection. The difference between full and partial standby is the difference between a note that solves your down payment and a note that does not.
| Feature | Full standby (counts as equity) | Partial standby (does not count) |
|---|---|---|
| Principal payments during the SBA loan term | None | Allowed after a set period |
| Interest payments during standby | None paid (may accrue on paper) | Interest paid to the seller |
| Counts toward the buyer's equity injection | Yes, up to 50% of the requirement | No, treated as subordinate debt only |
| Required standby length | Full life of the SBA loan | Less than the full life |
How full standby and partial standby differ for SBA equity-injection purposes (SBA SOP 50 10 8, effective June 1, 2025).
How Much of the Injection Can a Seller Note Cover?
A full-standby seller note can cover at most 50% of the required equity injection, which works out to 5% of total project cost when the injection requirement is 10% (SBA SOP 50 10 8, effective June 1, 2025). The other half of the injection has to be genuine, non-borrowed cash, at least 5% of total project cost.
Here is the math on a typical deal. The SBA requires a minimum equity injection of 10% of total project cost, which includes the purchase price plus closing costs, working capital, and any other completion costs. At least 5% of that total must be real cash the buyer is not borrowing. A full-standby seller note can supply the remaining 5%. So on a $500,000 total project cost, the buyer needs $50,000 of injection: $25,000 in genuine cash and up to $25,000 from a full-standby seller note.
A full-standby seller note can cover up to half of the required equity injection, capped at 5% of total project cost (half of the standard 10% requirement). The buyer must still bring at least 5% of total project cost in genuine, non-borrowed cash. A seller note cannot be your entire down payment under SBA rules, no matter how much the seller is willing to carry.
This is the single most common misunderstanding about seller financing in SBA deals. Buyers assume that if a seller will carry 10% of the price, that covers the whole injection and the buyer needs no cash. It does not. The cash floor is firm: at least 5% of total project cost in real money. The seller note fills the other half at most, and only on full standby. For the full breakdown of how the injection is built, see SBA equity injection explained.
Why Would a Seller Agree to a 0% Standby Note?
Full-standby seller notes are commonly structured at 0% interest paid during the standby period, because the SBA requires no payments at all while the note is on standby. The seller agrees to this because it is often the move that makes the deal close at the price they want. A seller who insists on cash up front may not find a buyer who can pay it.
The seller has real reasons to carry a standby note. First, it bridges a valuation gap: if the appraisal or the buyer's cash comes in short of the asking price, a seller note covers the difference and keeps the agreed price intact rather than forcing a price cut. Second, carrying paper signals the seller believes the business will keep performing, which makes the buyer and the lender more comfortable. Third, in many cases there is no all-cash buyer waiting, so a standby note is the path to actually selling.
A standby note is not a gift the seller makes for free. Interest typically accrues on the note even while no payments are made, so the seller is compensated over time once the standby period ends and the SBA loan is paid off. The seller trades immediate cash for a higher likelihood of closing and a continued, paper return. For a deeper look at the trade-offs, compare seller financing versus an SBA loan.
What Happens to the Note After the SBA Loan Is Paid Off?
Once the SBA loan is fully repaid, the seller note comes off standby and the buyer begins paying the seller the principal and any accrued interest under the note's terms. The full-standby requirement applies only while the SBA loan is outstanding, so the seller's wait ends when the lender is made whole.
During the standby period, the seller receives nothing in cash, but interest can accrue on the balance depending on how the note is written. When the SBA loan is paid off, whether on schedule after roughly 10 years or early through a refinance or resale, the standby restriction lifts. At that point the note converts to a normal repayment schedule, and the buyer pays down the principal plus whatever interest has built up.
In practice, many deals never reach the natural end of the standby period because the business is refinanced or sold before the 10-year SBA loan runs its full course. When that happens, the SBA loan is paid off at the refinance or sale, which clears the standby and the seller note is settled at the same time, often out of the proceeds. The key point is that full standby is tied to the SBA loan being outstanding, not to a fixed calendar.
When Is a Seller Note NOT Counted as Equity?
A seller note counts as zero equity any time it is not on full standby for the life of the SBA loan (SBA SOP 50 10 8, effective June 1, 2025). If the seller collects interest or principal while the SBA loan is still outstanding, the note is on partial standby, and the lender gives it no equity credit at all.
A seller note is not counted toward the equity injection when it is on partial standby (any payments to the seller during the SBA loan term), when it exceeds 50% of the required injection, or when it replaces the mandatory 5% genuine cash. In all of these cases the note still exists as subordinate debt behind the SBA loan, but it does zero work toward satisfying the buyer's down payment requirement.
There are three ways a seller note fails to count. The first is partial standby: any payment to the seller while the SBA loan is outstanding disqualifies the note as equity. The second is exceeding the cap: a note can cover at most 50% of the required injection, so the portion above that cap is just subordinate debt. The third is trying to use the note in place of the required cash: the buyer must bring at least 5% of total project cost in genuine, non-borrowed money, and no seller note substitutes for that floor. A note that fails on any of these counts is not equity, it is debt, and the buyer still has to fund the injection some other way. The mechanics of a properly structured full-standby note are covered in how full-standby seller notes work.
How Do You Structure a Seller Note That Actually Counts?
The note has to clear three tests at once: full standby for the life of the SBA loan, no more than 50% of the required injection, and a buyer cash contribution of at least 5% of total project cost in genuine, non-borrowed funds (SBA SOP 50 10 8, effective June 1, 2025). Miss any one of them and the note stops counting as equity.
This is where deals get built or broken. Structuring a seller note that survives the lender's review means writing the standby into the note correctly, sizing it against the injection requirement, and pairing it with the right amount of real cash. It also means confirming the rest of the structure works: who guarantees the loan, how the price compares to the independent valuation the SBA will require, and whether the seller is making a clean exit. A note that looks fine in isolation can still sink a deal if the surrounding structure is off.

Frequently Asked Questions
How does seller financing work in an SBA deal?
In an SBA 7(a) acquisition, the SBA loan funds most of the price, the buyer contributes cash, and a seller note can cover up to 50% of the required equity injection, but only on full standby (SBA SOP 50 10 8, effective June 1, 2025). The seller is paid only after the SBA loan, since the note sits behind it. Most small business sales include a seller note in some form.
What is a full-standby seller note?
A full-standby seller note is one where the seller receives no principal and no interest for the entire life of the SBA loan, typically 10 years (SBA SOP 50 10 8, effective June 1, 2025). Full standby is the only structure that lets a seller note count toward the buyer's equity injection. Interest may accrue on paper, but nothing is paid to the seller until the SBA loan is fully repaid.
How much will a seller carry?
Most small business sales include a seller note, and a full-standby note can count toward up to 50% of the required equity injection, which is 5% of total project cost on a standard 10% requirement (SBA SOP 50 10 8, effective June 1, 2025). Sellers often carry more than that as extra subordinate debt, but only the full-standby portion up to the cap counts as the buyer's equity.
Did the SBA seller-note rules change in 2025?
Yes. Under SBA SOP 50 10 8 (effective June 1, 2025), a seller note counts as equity only on full standby for the life of the SBA loan. The obsolete pre-SOP rule, where a 24-month standby could qualify the note as equity, is no longer valid. Any source still citing the 24-month rule is out of date, and relying on it can leave a buyer short on the injection at closing.
Can a seller note be my whole down payment?
No. A full-standby seller note can cover at most 50% of the required equity injection, and the buyer must still bring at least 5% of total project cost in genuine, non-borrowed cash (SBA SOP 50 10 8, effective June 1, 2025). A seller note cannot replace that mandatory cash floor, no matter how much the seller is willing to carry. The down payment is always part cash, part note at most.
What interest rate is on a seller note?
Full-standby seller notes are commonly written at 0% paid during the standby period, because the SBA allows no payments to the seller while the note is on standby (SBA SOP 50 10 8, effective June 1, 2025). Interest can still accrue on the balance and be paid once the SBA loan is repaid and the standby lifts. The headline standby rate is 0%, but the seller is typically compensated later through accrued interest.
Ready to Structure Seller Financing That Actually Counts?
A seller note is only as good as the structure behind it. Under the current SOP, a note that is not on full standby for the life of the loan does zero work toward your down payment, no matter how generous the seller is.
