SBA SOP 50 10 8.1: 7 Things Brokers Need to Know Before October 1

Quick Take: SBA SOP 50 10 8.1 takes effect October 1, 2026, rewriting how every 7(a) change of ownership gets underwritten. The debt service coverage floor rises to 1.25x, projections no longer count, and deals at $3 million or more now require a lender-ordered Quality of Earnings report.

The SBA issued SOP 50 10 8.1 on August 14, 2026. It takes effect October 1, and it is the most consequential rewrite of business acquisition lending since SOP 50 10 8 landed in June 2025. LinkedIn has been loud about it for three weeks, and we want to provide you with some key points. Here is what the document actually says, what it changes about your pipeline, and the one myth that keeps getting repeated by people.

1. The deadline is a loan number, not an application date

This is the single most actionable item in the entire SOP.

The new rules apply to loans that receive an SBA loan number on or after October 1, 2026. Applications that receive a loan number through September 30 stay under SOP 50 10 8. Submitting an application in September does not protect the deal. The number has to be assigned.

If you have acquisition files in process right now that would struggle under the new coverage math, that distinction is your whole September. Call your lenders this week and get honest answers about their processing queue, because a file that slips past September 30 gets underwritten against a different rulebook than the one you quoted your client on.

2. Change of ownership now lives in its own appendix, and it wins conflicts

SOP 50 10 8.1 pulls requirements that were scattered across the old document into seven new appendices, numbered 14 through 20, covering debt refinancing, changes of ownership, maximum guaranty amounts, loan maturity, interest rates, collateral, and application submission.

The one that matters most to brokers is Appendix 15, Changes of Ownership. It is now the controlling authority for acquisition deals. Where another section of the SOP conflicts with Appendix 15, Appendix 15 governs.

Appendix 15 sorts every change of ownership into one of four categories:

• Initial Acquisition: the default. A new majority or largest owner who was not previously an owner or employee of the target.

• Business Expansion: an existing operating business buying another business in the same industry.

• Owner Buyout: existing owners buying out other existing owners.

• ESOP and Cooperative: employee ownership structures.

The category is not cosmetic. The lender enters the transaction type into SBA's system, which means it is visible for SBA oversight, and the category determines the coverage test, whether the equity injection can be reduced, and whether a Quality of Earnings report is required. Knowing which box your deal falls in before you place it is now part of the job.

3. Coverage went to 1.25x, and projections are dead

Under the old SOP, a first-time buyer could clear a 1.15x debt service coverage test using projections. That is over.

For Initial Acquisition transactions, the coverage floor rises to 1.25x, measured on historical or adjusted trailing earnings rather than forecasts.

Think about what that does to a deal you would have placed in August. The buyer who was going to show the lender why next year looks better than last year no longer has that argument available. If the trailing numbers do not carry 1.25x after the new debt service, the loan amount comes down or the deal does not happen. Two things follow for brokers: qualify harder up front on historical cash flow, and stop building client expectations on a growth story the underwriter is no longer allowed to credit.

4. Quality of Earnings is now mandatory at $3 million and up

For Initial Acquisition and Business Expansion transactions where the business purchase price is $3 million or greater, excluding applicable owner-occupied real estate, the lender must obtain an independent Quality of Earnings report in addition to the business valuation. Owner Buyout and ESOP transactions are treated differently.

Two practical points your clients will not see coming.

First, the report is commissioned by and prepared for the lender. Your buyer may not get to choose the provider or the scope, even if they already paid for their own diligence.

Second, it has teeth. If the QoE findings do not support the valuation and the proposed debt structure, the loan amount comes down. This is not a formality that gets filed and forgotten.

Add cost and calendar to every deal above that threshold. Independent valuations alone commonly run in the low thousands with turnaround measured in weeks, and the QoE sits on top of that. If you are quoting timelines to a seller who is already impatient, build it in now.

5. The equity injection math changed, even though 10% did not

The headline number is unchanged. Initial acquisitions still require a minimum equity injection of 10% of total project costs. What changed is where that 10% is allowed to come from.

SOP 50 10 8.1 defines a category of Limited sources, which includes standby debt, seller debt on full standby, and, in the significant addition, equity from non-controlling minority investors, defined as investors holding under 20% with no control over the business. Individually or combined, Limited sources may supply no more than half of the required injection.

Run the arithmetic on a standard file. A $2.5 million project requires a $250,000 injection. Limited sources cap at $125,000, so at least $125,000 has to come from unlimited sources, which for most first-time buyers means the buyer's own unborrowed cash.

There is a second lock. Where minority investor equity is used to meet the injection, distributions to those investors beyond what covers their tax obligation on business income are prohibited until the 7(a) loan is repaid.

If you place deals for self-funded searchers or anyone raising a passive investor round, this reshapes the structure. The model where outside investors supply most of the injection does not survive this rule, and the distribution lockup needs to be in the operating agreement before the round is raised, not negotiated after the lender flags it.

6. The myth going around: seller notes still count

Here is the claim that has traveled furthest and is not supported by the text.

Multiple posts have asserted that seller notes no longer count toward the equity injection under 8.1. Lenders who have read the published document say the opposite. Seller debt that is subordinated to the lender and on full standby, meaning no payments of principal or interest for the term of the 7(a) loan, may still be considered as equity for SBA's purposes. What seller notes cannot do is exceed the Limited-source cap, and that 50% ceiling on standby seller debt already existed under SOP 50 10 8. Folding passive investor equity into that same capped bucket is the actual new part.

There is a related change worth knowing: reporting on the published text indicates seller note seasoning moved from 24 months to 36 months before the note can be refinanced. That is a seasoning change, not an eligibility change, and the distinction matters when you are advising a seller on structure.

If you have repeated the "seller notes are dead" version to a client, correct it this week. Being the broker who read the document instead of the LinkedIn post is worth more than any pitch deck.

7. Trusts, and the rest of the changes worth flagging

Trust ownership tightened meaningfully. Under 8.1, a Trust must guarantee the loan at any ownership percentage, and a Trustor must personally guarantee the loan regardless of whether the Trust is revocable or irrevocable. If you work with clients who hold ownership through estate planning structures, that conversation needs to happen before application, not at closing.

A few others that will touch your files:

• 7(a) Small Loan underwriting is out for changes of ownership, at any size. Acquisition deals under $350,000 no longer get the lighter treatment.

• The business portion of acquisition loans is capped at a 10-year amortization, and total debt is capped at the appraised business value.

• Sellers can now stay on as consultants for 24 months, up from 12, which is a genuine loosening and a useful transition tool.

• Lenders may refinance their own debt using delegated authority, which should speed up some refinance files.

• SBA Express loans with amortization schedules that prove too restrictive can be reissued before amortization begins to allow a longer revolving period.

• Business Expansion is the most favorable category in the new structure. An existing business with two full fiscal years under current ownership, buying a business in the same industry with no reduction in full personal guarantors, may have the 10% equity injection reduced or eliminated by the lender, and reporting on the text indicates a 1.15x coverage test rather than 1.25x. If you have clients who already own an operating business and are looking at a second, that is the strongest structure on the board right now.

The Bottom Line

SOP 50 10 8.1 does not shut the door on SBA acquisitions.

But it does raise the importance of getting the deal structure right before the file reaches underwriting.

The effective date is October 1, 2026, and the relevant trigger is when the SBA loan number is issued.

So for deals already moving through the pipeline, September may be an important month to revisit structure, underwriting assumptions and lender expectations before the new SOP takes effect.
