If you are buying a small business with an SBA 7(a) loan and your lender has not yet issued your SBA loan number, the rules of your deal changed on Thursday, October 1.

On August 14, 2026, the Small Business Administration issued Information Notice 5000-880695 announcing SOP 50 10 8.1, the new version of the rulebook lenders follow for 7(a) and 504 loans. It applies to every application that receives an SBA loan number on or after October 1, 2026. Not every application submitted after that date: every application numbered after it. A deal that was in underwriting in September but did not get its number before October 1 is under the new rules.

The headline for buyers is that SBA acquisition financing got more structured and somewhat stricter. The headline for sellers is that the seller note, the piece of the deal that so often closes the gap between what the buyer has and what the bank will lend, is more constrained than it was.

Three versions in five years

It helps to see where this came from.

SOP 50 10 7 and 7.1 (2023). The SBA loosened acquisition lending considerably. Equity injection for a complete change of ownership stayed at 10%, but lenders got broad discretion to follow their own policies for similar non-SBA loans (the so-called “do what you do” approach). Seller notes could count toward the buyer's equity if they were on full standby for just the first 24 months of the loan, and even partial-standby notes (interest-only) could count in some cases. SOP 50 10 7.1 took effect November 15, 2023, according to SBA Procedural Notice 5000-848663.

SOP 50 10 8 (June 1, 2025). The SBA reversed course. The 10% minimum injection was firmly reinstated for changes of ownership and startups, “do what you do” was eliminated, and a seller note could count toward equity only if it was on full standby for the entire life of the SBA loan, no principal, no interest, and then only for up to half of the required injection.

SOP 50 10 8.1 (October 1, 2026). The new version keeps 8.0's tighter posture and reorganizes change-of-ownership lending into a dedicated appendix (Appendix 15) with separate rules for different kinds of deals.

What did not change

The 10% minimum equity injection for a complete change of ownership. If you are buying 100% of a business you do not already own, you still need to put in at least 10% of the total project cost, meaning the purchase price plus closing costs, working capital, and other uses of the loan. Under 8.1, that minimum cannot be reduced for a first-time buyer.

Full standby means full standby. A seller note still counts toward your equity only if the seller agrees to take no payments of principal or interest for the full term of the 7(a) loan. A note with payments, or with interest-only payments, does not count as equity.

What changed

The details below come from the SBA notice and from lender-side and law-firm summaries of Appendix 15. We were not able to review the full SOP text directly, and the summaries agree on most points but not all. Ask your lender to confirm any item that matters to your deal.

Four transaction categories. Appendix 15 sorts changes of ownership into initial acquisitions (a new owner buying in), business expansions (an existing business buying another in its industry), owner buyouts (existing owners buying out a partner), and ESOP/cooperative transactions. The equity, coverage, and diligence rules differ by category. Most individual buyers are doing an initial acquisition.

“Limited” versus “unlimited” equity sources, with a 50% cap. This is the most important structural change. Equity sources are now sorted into two buckets:

Under 8.0, the 50% cap applied to the seller note. Under 8.1, multiple summaries report that it applies to all limited sources combined. If you were planning to cover half your injection with a seller note and a chunk of the rest with money from a few passive investors, that structure no longer works.

Higher cash-flow coverage, based on history, not projections. Summaries consistently report that initial acquisitions, owner buyouts, and ESOP deals now require a debt service coverage ratio of at least 1.25 to 1, up from 1.15 to 1, while business expansions stay at 1.15. Coverage must be shown on historical or adjusted historical earnings. A buyer's projections of what the business will do after closing generally cannot make up a shortfall.

Quality of earnings for larger deals. Initial acquisitions and business expansions with a business purchase price of $3 million or more (excluding owner-occupied real estate) now require a quality of earnings report, including a “cash proof” that reconciles bank deposits to the financial statements and tax returns. Several summaries report that the lender commissions the report.

Longer seller transitions. A selling owner can stay on as a consultant for up to 24 months, up from 12.

Longer seasoning before refinancing seller debt. Several summaries report that seller debt created in a 7(a) change of ownership must be in place and current for 36 months (up from 24) before it can be refinanced. We could not confirm this in the SOP text itself. Treat it as likely, and verify with your lender.

Citizenship and residency. Separately from 8.1, the SBA issued Policy Notice 5000-876441 in February 2026, which 8.1 now incorporates. It requires 100% of the direct and indirect owners of an SBA borrower to be U.S. citizens or U.S. nationals, and makes lawful permanent residents ineligible to hold any ownership interest. Earlier exceptions for small foreign ownership stakes were rescinded. If anyone in your buying group holds a green card rather than citizenship, raise this with your lender on day one.

No light-touch underwriting for small acquisitions. Reports agree that the streamlined “7(a) small loan” process is no longer available for any change of ownership, regardless of size. Every acquisition gets a full credit memorandum and a business valuation.

A worked example

Say you are buying a commercial cleaning company for $2,000,000. Closing costs, a small working-capital cushion, and the SBA guaranty fee bring total project costs to $2,100,000.

Equity injection. Ten percent of $2,100,000 is $210,000. Under 8.1:

So if the seller agrees to carry a $105,000 note on full standby for the life of the loan, you need $105,000 of your own cash. If you also hoped a friend would invest $50,000 for a 10% stake, that $50,000 counts toward the same $105,000 limited-source cap. It cannot replace your cash.

The loan. The 7(a) loan covers the remaining $1,890,000. At an illustrative 9.75% interest rate on a 10-year term, annual debt service is roughly $296,600.

Coverage. At the old 1.15 ratio, the business would need about $341,100 of available cash flow, based on its historical results, to support that payment. At the new 1.25 ratio, it needs about $370,700: roughly $29,700 more every year, measured on what the business has actually earned, not on your plan for it. On a business producing $350,000 a year, that is the difference between an approved deal and a declined one, or a renegotiated price.

Diligence. At a $2 million price, no quality of earnings report is required by the SOP. At $3 million, it would be. Many lenders will ask for one anyway on deals close to the line.

A typical scenario

Consider a buyer who was under contract this summer to buy a regional HVAC service company. The structure, negotiated in the spring, used a seller note for half the equity and a small investment from two family members for most of the rest. The lender's commitment letter arrived in late August with a note that the loan would be numbered after October 1.

Under 8.1, the family money and the seller note were now in the same capped bucket, and the buyer's own cash fell short of the required half. The deal survived because the seller agreed to a price reduction and the family members converted their investment into a personal loan to the buyer, repaid from the buyer's own income, which reportedly can count as an unlimited source. That took three weeks of renegotiation and an amended purchase agreement. If the parties had built the structure with the new rules in mind, it would have taken none.

What buyers should do differently

For the broader acquisition process, see how to buy a small business and financing a business acquisition. And remember that under SBA regulations, every owner of 20% or more of the borrower must personally guarantee the loan, a topic covered in personal guarantees on business loans.

Frequently Asked Questions

Does the 10% equity injection apply to partial buyouts?

Owner buyouts and business expansions are treated as separate categories. Summaries indicate that, unlike initial acquisitions, the 10% injection in those categories can be reduced or eliminated when the borrower shows sufficient liquidity, working capital, and positive net worth. Confirm with your lender.

Can a seller note with payments still be part of the deal?

Yes, as financing, but not as equity. A note with scheduled payments does not count toward the injection, and its payments are included when the lender tests debt service coverage, which makes the 1.25 ratio harder to meet.

We submitted our application in September. Are we grandfathered?

Only if your loan received its SBA loan number before October 1, 2026. Submission alone does not lock in the old rules.

Is there still a maximum 7(a) loan amount?

Yes. The 7(a) program maximum remains $5 million, and 8.1 coordinates the 7(a) and 504 limits for borrowers using both. Ask your lender how the cap applies if your deal combines programs.
