SOP 50 10 8.1: The New SBA Rules for Buying a Business (October 1, 2026)

The short answer: on acquisitions at $3 million and above, the earnings number that determines your loan size stops originating with the seller and starts originating with an independent professional the lender relies on. Below $3 million, nothing in this rule changes — and that is most of this market.

The date that matters is the loan number, not the closing

This is the part most likely to catch a deal that is already moving.

SBA Information Notice 5000-880695, published August 14, 2026, states that SOP 50 10 8.1 "will become effective October 1, 2026, and will apply to all applications that are issued an SBA loan number on or after that date." It continues: "SBA Lenders and SBA employees must continue to use SOP 50 10 8.0 for 7(a) and 504 applications submitted through September 30, 2026."

So the governing question is not when you sign the purchase agreement, and not when you fund. It is when the SBA loan number was issued.

That asymmetry creates a real incentive in September. Expect lenders to be busy, and expect some sellers and brokers to push for speed on the argument that the old rules are easier. That argument is true as far as it goes. Whether it is in your interest is a different question, and the rest of this post is why.

What triggers the requirement

Three conditions, and the interaction is where deals get misread.

1. Transaction type

The requirement applies to Business Expansion and Initial Acquisition transactions. If you are buying a business you do not currently own, you are an Initial Acquisition.

2. Business Purchase Price at or above $3 million

Not total project cost. Not the loan amount. Not enterprise value including real estate. The specific defined term is Business Purchase Price.

3. Real estate comes out before you apply the test

Per the SOP, "the 'Business Purchase Price' excludes all owner-occupied commercial real estate assets being acquired in the transaction." And: "When real estate is part of the acquisition, the Lender must remove the appraised value of the real estate from the price set by the purchase and sale agreement to determine the Business Purchase Price for purposes of financial due diligence requirements."

That single clause moves a lot of deals across the line, in both directions.

Note the second row. A larger headline price than the first row, and no QoE requirement, because most of what is being bought is the building.

4. Structure cannot get you under the line

The SOP is explicit: "The $3 million threshold is determined before the application of buyer equity, seller debt, or other financing sources."

Putting more cash down does not help. Moving more onto a seller note does not help. Splitting the transaction is a different conversation, and one to have with counsel rather than a spreadsheet.

What the report has to contain

This is where 8.1 goes further than most summaries suggest. It is not a request for "a QoE" as a category of document. The SOP specifies the procedure.

The Cash Proof

Per SOP 50 10 8.1, a Cash Proof "is a financial analysis that independently reconstructs cash receipts and disbursements by reconciling bank statement data to the income statement and tax return for each period under review." It is "designed to identify discrepancies in income and undisclosed expenses," and it "must be performed on both a trailing 12-month basis and the last two fiscal years."

Read the direction of travel there. Most diligence starts with the accounting records and adjusts them. A Cash Proof starts with the bank statements and works back to what was reported. It asks how much of the revenue on the P&L actually arrived, and how much of what left the account appears in the expense lines.

That is three reconciliations — trailing twelve, and each of the two prior fiscal years — not one.

The reconciliation set

The SOP also requires the QoE analysis to reconcile the business's accountant-prepared financial statements, tax returns, internal statements and IRS transcript data. Four sources that, in a small business, frequently disagree.

The add-backs it must document

The report "must identify and document all add-backs and adjustments to the seller's reported earnings," and the SOP names the categories:

If you have ever been handed an add-back schedule that was a column of numbers with no support behind it, this is the requirement that ends that on deals of this size.

How the QoE sizes your loan

This is the clause with teeth, and it is worth quoting in full.

Per SOP 50 10 8.1: "When a change of ownership transaction requires a Quality of Earnings (QoE) report as part of the necessary financial due diligence, the Lender must use the report's findings to calculate the Debt Service Coverage. If that Debt Service Coverage does not support the business valuation and proposed debt structure, the loan amount must be reduced accordingly. Additional equity (unlimited or limited) may be used to make this adjustment."

So the sequence on a qualifying deal is mechanical:

1. The QoE produces an earnings figure, reconciled to bank statements across three periods.
2. The lender calculates Debt Service Coverage from that figure.
3. If the DSC does not support the valuation and the proposed debt, the loan is reduced.
4. You close the gap with equity, or you renegotiate, or the deal does not happen.

The seller's adjusted-earnings schedule is an input to the discussion. It is no longer the basis of the decision.

The DSC minimums

The ratio must be satisfied using either the last fiscal year-end or an average of the last two fiscal year-end statements, on a historical or adjusted basis depending on the transaction type:

Note that Initial Acquisition — buying a business you do not already own — carries 1.25:1 rather than the 1.15:1 floor that gets quoted most often in general SBA coverage.

Which transactions are exempt, and why

Owner Buyout and ESOP and Cooperative transactions are not subject to the QoE requirement.

The SOP gives its reasoning: these transactions are exempt "because the existing owner(s) retain operational knowledge of the business and the transaction does not result in a change to the management or operating structure."

That is a more interesting rationale than it first appears. The SBA is not saying these deals are lower-risk financially. It is saying the specific risk a QoE addresses — that the person relying on the numbers does not know the business — is absent when the buyer is already inside it.

Which tells you what the rule is really for. It exists to protect a buyer who is taking someone else's word for the earnings, and the lender standing behind that buyer.

What did not change

Worth stating plainly, because a rule change invites over-reading.

The Business Valuation requirement. Still required, still to the same standards, still by an accredited and independent appraiser. The QoE sits alongside it.

Anything below $3 million. No QoE requirement. Given that the median SBA-financed acquisition sits well under $1 million, most transactions in this market are unaffected by this specific rule.

The tax transcript requirement. The SOP treats transcripts as an extension of the financial due diligence requirements, and lenders must still validate seller-reported information against them.

Your own diligence obligation. A lender-obtained QoE is not your diligence. It is the lender's. It may not be prepared for you, and you should not plan your investigation around reading it.

If you are buying at this size, do these five things

1. Get the loan number date in writing. It decides which SOP governs your deal. Nothing else does.
2. Ask for bank statements at LOI. Twelve months minimum, and the two prior fiscal years to match what the Cash Proof will cover. Reconcile one month yourself before you spend money on anything else.
3. Split the price before you test the threshold. Appraised owner-occupied real estate comes out first. Know your Business Purchase Price, not your headline price.
4. Test the five add-back categories by name. Which "one-time" items appeared last year too? What does a market-rate replacement for the owner cost? Who owns the building?
5. Model debt service on the QoE figure, not the schedule figure. If the deal only works on the broker's number, at this size you do not have a deal — you have a bet that an independent reconciliation will agree with a sales document.
