SBA Seller Note Rules: Standby, Equity Injection and Taxes
An SBA seller note is a loan the seller of a business makes to a buyer who is financing the rest with an SBA 7(a) loan. Under SBA's rules, a seller note counts toward the buyer's required equity injection only if it is on full standby, meaning no principal and no interest payments for the whole term of the SBA loan, and even then it can cover no more than half of the required injection. For the seller, the note is still an installment sale under §453, but standby means years with no cash, a lien behind the bank, and possibly tax on interest you have not been paid.
Which SBA rules apply: SOP 50 10 8 and 8.1
SBA's lending rules are in its Standard Operating Procedure, SOP 50 10. Two versions matter right now:
- SOP 50 10 8, effective June 1, 2025.
- SOP 50 10 8.1 with Technical Policy Updates, published September 25, 2026 and effective October 1, 2026. It rewrites the change-of-ownership rules into a new Appendix 15, "7(a) Changes of Ownership."
Both are on sba.gov. Ask the buyer's lender which one governs the loan, and confirm the terms before you sign; SBA changes them often.
The equity injection and where a seller note fits
The minimum is 10%. Under SOP 50 10 8.1, Appendix 15 (Credit Standards, Underwriting, Equity Requirements), the minimum equity injection for an Initial Acquisition, a buyer who was not already an owner, is 10%, and "the required equity injection cannot be reduced or eliminated." The base is total project cost: "all costs required to become operational, regardless of the source of funds, except for lines of credit and 504 loans." Other deal types also start at 10%, but for Business Expansions and Owner Buyouts the lender may reduce or eliminate it. SOP 50 10 8 also set 10% of total project costs for a complete change of ownership (Section B, Ch. 1, equity requirements).
Seller debt counts only on full standby. SOP 50 10 8.1 lists seller debt among the "Limited Equity Injection Sources," and says: "Seller debt that is subordinated to the Lender and on full standby (no payments of principal or interest for the term of the 7(a) loan) may be considered as equity for SBA's purposes."
Half is the cap. The limited sources, "whether individually or in the aggregate, may provide no more than half of the required Equity Injection." SOP 50 10 8 said the same thing directly: seller debt may not count "unless it is on full standby for the life of the SBA loan, and it does not exceed half of the SBA-required equity injection."
So with a 10% required injection, a standby seller note can supply at most 5% of project cost as equity; the buyer brings the rest, for example in unborrowed cash.
What full standby means for the seller
The standby rules in SOP 50 10 8.1 (Appendix 15, Standby Debt Agreements) spell it out:
| Rule | What it means for you |
|---|---|
| No payments of principal or interest for the term of the 7(a) loan | No cash from the note until the SBA loan is paid off. A change-of-ownership 7(a) loan can amortize over up to 10 years (longer only for the real estate portion), so plan on waiting that long |
| Interest may accrue and be added to the standby debt, then amortized after the 7(a) loan is paid in full | You can earn interest, but you collect it later |
| SBA Form 155 or the lender's equivalent Standby Agreement, with your note attached | You sign an agreement with the buyer's lender, not just a note with the buyer |
| You must subordinate any lien rights and take no action against the borrower or collateral without the lender's consent | You cannot enforce the note on your own |
| The provider of standby debt may not take an equity investment in the business | You cannot also hold an equity stake in the business |
"Partial standby" is a term lenders use for seller notes that pay interest only for a period. The SOP does not treat that as equity: only full standby counts. Seller debt that is not on full standby is ordinary debt the lender underwrites. Under SOP 50 10 8.1, total debt including seller debt not on full standby is limited to the business valuation, and if that debt is interest-only, the lender must assume an amortization of no more than 10 years when testing debt service.
Other SBA rules that affect sellers
- No earnouts. "Seller earnouts are prohibited" (SOP 50 10 8.1, Appendix 15, change of ownership requirements). Buyer rebates tied to performance are allowed.
- You generally cannot stay on. In an Initial Acquisition or Business Expansion, the seller may not remain as an officer, director, stockholder or employee. The business may hire you as a consultant for up to 24 months in total under SOP 50 10 8.1; SOP 50 10 8 allowed 12 months.
- Selling part of your stake. In an Owner Buyout with a partial change of ownership, the seller may stay on. A selling owner who keeps less than 20% must provide a guaranty of the full loan amount for at least two years after final disbursement (SOP 50 10 8.1, Appendix 15, Owner Buyout).
- Refinancing your note. Seller debt may be refinanced with a new SBA loan only after it has been in place and current, not on standby, for at least 36 months under SOP 50 10 8.1 (24 months under SOP 50 10 8), and the refinance must meet SBA's 10% payment improvement test.
- The price must be supported. The lender orders its own business valuation (plus a Quality of Earnings report on Initial Acquisitions and Business Expansions of $3 million or more under SOP 50 10 8.1); any price above the valuation must be made up by equity.
How the seller note is taxed
A standby note is still an installment sale. It is the buyer's note given for the business assets, so receiving it is not a payment (Temp. Reg. §15a.453-1(b)(3)(i)), and you report the gain in it as principal is paid (§453). Standby changes when you are paid, not how the note is taxed. Later is fine for tax; the cost is a decade of subordinated waiting.
Not every asset can be spread. In an asset sale, the price is allocated across asset classes using the residual method and reported on Form 8594 by both sides (IRS Pub. 537). Then:
- Inventory cannot use the installment method (§453(b)(2)(B)).
- Depreciation recapture on equipment (§1245) is taxed in full in the year of sale, even if you receive no cash for it that year (§453(i)).
- Receivables of a cash-method business have no basis and are ordinary income. Ask your CPA how they are handled in your deal.
- Goodwill and other capital assets can generally use the installment method.
See Form 8594 instructions, §1245 recapture and selling a business: taxes.
Accrued interest can be taxed before you get it. Interest counts as "qualified stated interest" only if it is unconditionally payable at least annually (Treas. Reg. §1.1273-1(c)). Interest that accrues on standby and is paid after the SBA loan is gone does not meet that test, so the note will usually carry original issue discount under §1274, which the holder includes in income as it accrues (§1272(a)(1)), cash or no cash. One way out: for smaller notes, buyer and seller can jointly elect under §1274A(c) to report interest on the cash method, when paid. The election requires a stated principal within a dollar limit in the statute that is adjusted for inflation each year, and a seller who is not on the accrual method. Have your CPA check whether your note qualifies and draft the election into the closing documents.
Big notes can bring an interest charge. If more than $5,000,000 of installment obligations from the year's sales (each over $150,000) are outstanding at year end, §453A charges interest on the deferred tax. See the §453A guide.
Simple example: a $2,000,000 business with a 10% standby note
Simple example (illustrative). An owner sells a business to an outside buyer (an Initial Acquisition) for $2,000,000 in an asset sale. To keep it simple, total project cost equals the price (real deals add closing costs and working capital). The price is allocated: inventory $150,000 (basis $150,000), equipment $250,000 (adjusted basis $50,000, original cost $400,000), goodwill $1,600,000 (basis $0).
Financing. The required injection is 10% of $2,000,000, or $200,000. The seller carries a $200,000 note (10% of the price) on full standby at 7%. Only $100,000 of it can count toward the injection (the half cap), so the buyer brings $100,000 in cash. The SBA 7(a) loan is $1,700,000, amortizing over 10 years. The other $100,000 of the seller note is additional seller debt the lender underwrites; lenders structure this in different ways, so expect the terms to be negotiated.
Seller's gain. Inventory: $0. Equipment: $200,000, all §1245 recapture. Goodwill: $1,600,000. Total gain: $1,800,000. For simplicity, assume the note is allocated to the goodwill (how payments are allocated among assets is a question for your CPA).
| Amount | When taxed | |
|---|---|---|
| §1245 recapture on equipment | $200,000 ordinary | Year of sale (§453(i)) |
| Goodwill gain paid at closing | $1,400,000 capital | Year of sale |
| Goodwill gain in the standby note | $200,000 capital | As note principal is paid, after the SBA loan is paid off |
| Gain taxed in year one | $1,600,000 |
The waiting. If the note accrues 7% compounded annually for 10 years of standby, the balance grows to about $393,430 ($200,000 × 1.07 to the 10th power). That is $193,430 of interest you have not received. Unless the note qualifies for the §1274A(c) cash-method election, you would report that interest as it accrues, starting at $14,000 in year one ($200,000 × 7%), without receiving a dollar of it. And your $393,430 claim sits behind the SBA lender for the whole decade.
A standby note may be what makes the buyer's financing work, and it is sometimes the right trade, especially when you want this buyer and the deal does not happen without it. See seller financing a business sale and how to structure seller financing.
Getting paid over time without a standby note
If the buyer can bring the full equity injection from cash or other unlimited sources, you may not need to carry a note at all to get installment treatment. The buyer's SBA loan plus equity pays the full price at closing. Before closing, the purchase agreement directs part of the price to an assignment company, which takes on the obligation to pay you on a schedule you choose. You report the gain under §453 as the payments arrive, and the payments start on your schedule, not after a 10-year standby.
Simple example, continued. Same $2,000,000 sale. The buyer brings $200,000 in cash and borrows $1,800,000. The seller takes $1,600,000 at closing and structures $400,000 of the goodwill proceeds as $40,000 of principal a year for 10 years. Year-one gain: $200,000 of recapture plus $1,200,000 of goodwill, or $1,400,000, compared with $1,600,000 under the standby note. The remaining $400,000 of goodwill gain is taxed at $40,000 a year as it is received.
Structured sales of business interests and goodwill are done, but have your CPA confirm which assets qualify: inventory does not, and recapture is taxed in year one regardless.
| SBA standby seller note | Structured installment sale | |
|---|---|---|
| Cash at closing | Price minus the note | Full price is paid; you choose how much to take now |
| When payments start | After the 7(a) loan is paid off | On the schedule you pick |
| Tax on the deferred portion | As principal is paid (§453) | As payments are received (§453) |
| What backs the payments | The buyer's promise, with any lien subordinate to the SBA lender | The assignment company's promise, funded by an annuity it owns. You hold no lien on the annuity or the building. |
| Accrued interest taxed before paid | Possible (§§1272, 1274) unless the cash-method election applies | No: payments begin on schedule |
| Rate | Negotiated, usually higher | Usually lower |
| Flexibility | Can be renegotiated with lender consent, or sold (a sale triggers the tax under §453B) | None: the schedule cannot be changed, sold or pledged |
| Helps the buyer's equity injection | Yes, up to half of the required injection | No |
The last row matters: if the buyer needs your standby note to meet SBA's equity rules, a structured sale does not replace it. It fits when the buyer has the equity.
What to know before you choose it. It has to be set up before closing; a note you already hold cannot be converted. The payments are locked in: you can't speed them up, borrow against them, pledge them or cash them out, and that is what keeps the deferral intact. There is no free look after closing: once the sale closes, the structure cannot be undone. The payments depend on the assignment company's ability to pay. The structure rests on settled installment-sale law, but this specific assignment structure has no published IRS ruling, so have your CPA or tax attorney review the documents. A commission is built into the pricing: Hans is paid about 2.4% of the amount structured, only if a structured sale is funded; seller financing pays him nothing (see the disclosures).

Bottom line
On full standby, an SBA seller note can cover up to half of the buyer's 10% equity injection. For the seller, it means no payments until the SBA loan is paid off, a lien behind the bank, and possibly tax on interest that has only accrued. If the buyer has the equity, a structured installment sale set up before closing can spread the gain with payments that start right away. SBA's rules change often, and SOP 50 10 8.1 takes effect October 1, 2026, so confirm the current terms with the buyer's lender.
Questions to ask your CPA or attorney
- Which version of SOP 50 10 governs this buyer's loan, and what exactly does the lender's standby agreement say?
- How is the purchase price allocated on Form 8594, and how much of my gain is inventory, receivables or recapture taxed in year one?
- If my note accrues interest on standby, will I owe tax on it before I am paid, and does the note qualify for the §1274A(c) cash-method election?
- Does the note's rate meet the applicable federal rate for its term?
- What happens to my note and my tax if the business fails while I am on standby?
- If the buyer can bring the full injection, which of my assets could go into a structured installment sale?
