Buyer Guide · SBA SOP 50 10 8.1 · Effective October 1, 2026

Buying a business under $3M after Oct. 1? The mandatory QoE rule probably doesn't apply to you — here's what actually does.

SBA's new SOP 50 10 8.1 takes effect October 1, 2026 (SBA Information Notice 5000-880695, issued August 14). Most of the coverage has been about one line in it: a mandatory Quality of Earnings (QoE) report on $3M+ acquisitions. That line doesn't touch most of the deals I see. Other lines in the same SOP do. Here's the whole picture, for your deal.

One timing point first. The SOP applies to loans that receive their SBA loan number on or after October 1 — not loans applied for after October 1. A file submitted to a lender on September 25 that doesn't clear E-Tran until October 2 is underwritten under the new rules. If you're mid-process, ask your lender today which side of the line you're on.

The 2-minute version

Question If yes
Is the loan an SBA 7(a)? Keep going
Is it an Initial Acquisition or Business Expansion? Keep going
Is the business price $3M+ (excluding owner-occupied real estate, before equity and seller note)? Mandatory lender-engaged QoE

Any "no" and the mandatory rule doesn't apply to you.

1. Who's actually covered

SOP 50 10 8.1 moves change-of-ownership rules into their own appendix (Appendix 15) and sorts every deal into four buckets:

The mandatory QoE applies to the first two only, and only when the business purchase price is $3M or more. Owner buyouts, ESOPs and co-ops are exempt at any price.

How the $3M is measured matters more than the number:

Once it applies, the lender has to use the QoE-derived earnings in its debt-service coverage calculation and keep the report in the credit file. The QoE isn't a formality on those files. It's the number.

2. Who's NOT covered — and why you should do it anyway

Under $3M, nothing in the SOP forces a QoE. That covers every deal I've quoted this year. But four other things in the same SOP change how your lender reads your file, whatever the size:

  1. Coverage is on history, not projections. An Initial Acquisition needs 1.25x debt-service coverage, on last fiscal year's earnings or an average of the last two. Your model showing year-two growth doesn't count toward the floor.
  2. 10-year maturity on the business piece. Business-acquisition proceeds carry a 10-year maturity in the calculation. If real estate is included, the lender must use separate loans or a weighted-average maturity; real estate can no longer stretch the entire acquisition loan to 25 years. Higher payment, less room in the coverage math.
  3. 7(a) Small underwriting is gone for changes of ownership. Every acquisition gets full underwriting, including deals under $350K.
  4. Seller notes count as equity only on full standby. No principal or interest for the life of the 7(a) loan, 36 months seasoned before it can be refinanced, and standby debt plus minority investor equity can't be more than half of your required injection.

Put those together: the lender is underwriting your deal on the seller's actual historical earnings, with a higher payment and a stricter coverage floor. If the seller's add-backs are soft, that shows up as a coverage problem. You want to know that in September, before you've spent on legal, environmental and the deposit — not in November when the credit committee sends it back.

The other reason: the mandatory report, where it applies, is written for the lender. Its job is to protect the lender's collateral. It's not scoped to your questions and you don't direct it. On any deal, the report that tells you whether you're paying the right price is the one you commission.

3. What "independent" actually means

The SOP language is "an independent, experienced financial professional," engaged for the lender's benefit, and the report may not be prepared by or for the borrower or the seller. In practice, on a covered deal:

4. What a good QoE report should actually include

Whether your lender orders it or you do, here's what to check for before you accept any provider's report. This is vendor-agnostic. If a report is missing any of these, ask why.

Watch for the word "verified" with no procedures behind it, valuation opinions mixed into a diligence report, and any report with no cash proof on a deal where bank statements were available.

5. Three questions to ask your lender this week

  1. "Will my loan number issue before October 1, or are we underwriting under 8.1?" If you're mid-process, this decides which rulebook applies.
  2. "What earnings figure are you underwriting to — last fiscal year, a two-year average, or trailing twelve — and what do you need to see behind the add-backs?" The answer tells you what your diligence has to prove.
  3. "Do you have a QoE provider list, and on a deal under $3M do you accept a buyer-commissioned report?" On a $3M+ deal, ask who's on the list, what it costs, how long it takes, and whether they're still adding names.
