Most business buyers finance their transactions with a Small Business Administration (SBA) 7(a) loan. The underwriting documentation package for an SBA loan looks very similar to what buyers would anticipate: three years of business and personal tax returns, a completed Personal Financial Statement (SBA Form 413), a current debt schedule, year-to-date profit & loss statements and balance sheets, forward looking cashflow projections, and resumes for all buyers. SBA lenders also review personal credit, with a minimum score around 650 and most preferring 680 or higher. These underwriting requirements are standard across SBA lending, regardless of industry.
New SBA Standard Operating Procedure (SOP) 50 10 8.1
The SBA released SOP 50 10 8.1 on August 14, 2026, and reissued it with technical updates on September 25, 2026. It takes effect on October 1, 2026. This update is one of the most consequential changes in recent years.
Below is an overview of the SBA underwriting requirements comparing SOP 50 10 8 vs. the new SOP 50 10 8.1. It is not intended to be comprehensive and is based on our interpretation of the latest SOP as of September 25, 2026; therefore, it is crucial to consult with an SBA lender to verify the underwriting requirements.
Transaction Categories
- SOP 8 had three: complete change of ownership, complete partner buyout, and partial change of ownership.
- SOP 8.1 has four: Initial Acquisition (the default), Business Expansion, Owner Buyout, and ESOP/Cooperative.
- The lender must document why a transaction qualifies for any category other than Initial Acquisition.
- SOP 8 allowed Lawful Permanent Residents to be owners and guarantors.
- SOP 8.1 makes them ineligible. 100% of buyers and guarantors must be U.S. citizens or nationals whose principal residence is in the U.S., its territories, or possessions.
- SOP 8 allowed complete change of ownership, complete partner buyouts, and partial change of ownership transactions up to $350,000 under less stringent 7(a) Small underwriting requirements and each had their own equity injection rules.
- SOP 8.1 requires the loans to meet the same change of ownership rules as Standard 7(a) loans, including the transaction categories, equity injection, and debt service coverage requirements. The lender does not have to take a lien on other commercial real estate owned by the buyer or guarantors to meet the fully secured requirement.
- SOP 8 allowed loans of up to $500,000. Lenders used the underwriting procedures their own policies required, and the decision whether to require an equity injection was left to the lender's judgment.
- SOP 8.1 requires the loans to meet the same change of ownership rules as Standard 7(a) loans, including the transaction categories, equity injection, and debt service coverage requirements. The lender does not have to take a lien on other commercial real estate owned by the buyer or guarantors to meet the fully secured requirement.
- SOP 8 required the same 6-digit NAICS code and geographic area, identical ownership, and no equity injection.
- SOP 8.1 requires the business to have operated for at least two full fiscal years under its current ownership, the acquisition target to be in the same 4-digit NAICS group, at least as many full personal guarantors as the acquiring business's ownership structure would have required before the transaction, and a 10% equity injection that the lender may reduce or waive.
- SOP 8.1 adds that in an Owner Buyout, individuals employed less than 24 months may acquire less than 50% and cannot become the largest owner. If they acquire 50% or more or become the largest owner, the transaction must meet the Initial Acquisition credit standards (1.25x DSC, 10% equity injection that cannot be reduced, and a QoE if applicable), but the seller may remain an owner and employee.
- SOP 8.1 adds individuals employed at least 24 consecutive months can buy out an owner's entire interest as an Existing Owner Buyout transaction, including buying 100% from a sole owner.
- Seller Consulting Period
- SOP 8 allowed 12 months for a complete change of ownership.
- SOP 8.1 increases it to 24 months for an Initial Acquisition and Business Expansion.
- SOP 8 and SOP 8.1 both state a business is an ineligible passive business if an agreement, such as a management or consulting agreement, gives a third-party sole discretion to manage its operations, including decisions over employees, finances, and bank accounts, with no involvement by the owners. If the owners keep meaningful oversight, it remains eligible. A seller consulting agreement should be structured as advisory only.
- Seller Note Refinancing
- SOP 8.0 the waiting period was 24 months.
- SOP 8.1 the waiting period increases to 36 months.
- SOP 8.1 also adds that the refinance must not reduce the lender's exposure (the 10% payment-improvement requirement applied under both SOPs).
- Buyer Rebates
- SOP 8 required rebates to pay down the loan only to the point that avoided the subsidy recoupment fee with any excess usable for business purposes.
- SOP 8.1 requires all rebates to be applied to principal reduction with no subsidy recoupment fee.
- Full-Amount Guaranty from a Partial Seller Retaining Less Than 20%
- SOP 8 required the guaranty for the later of two years after final disbursement or until the loan had been current for twelve consecutive months.
- SOP 8.1 requires at least two years after final disbursement. The guarantor may be released only if the loan has been current for the 12 consecutive months before release.
- Paying Off the Seller's Existing SBA Loan
- SOP 8 stated the buyer should be offered the option to assume the seller’s existing loan for a complete change of ownership.
-
SOP 8.1 no longer includes the assumption-offer language. It continues to provide that when an Initial Acquisition pays off the seller's existing business debt (including an SBA loan) with the buyer's loan proceeds, the payoff is not treated as a refinance under SBA's debt refinancing rules. It is part of the purchase and must meet SBA's change of ownership requirements.
Valuation and Due Diligence
- Business Valuation
- SOP 8 allowed the lender to perform its own valuation when total financing (7(a), 504, seller, or other) minus the appraised value of real estate and equipment was $250,000 or less, unless there was a close relationship between the buyer and seller (for example, existing owners or family members).
- SOP 8.1 requires a valuation to be prepared for the lender (not the buyer or seller) by an independent Qualified Source (ASA, CBA, ABV, CVA, or BCA credential) when the business purchase price is more than $350,000 or the buyer and seller have a close relationship.
- SOP 8.1 allows the lender to perform its own valuation when the business purchase price is $350,000 or less.
- SOP 8.1 allows ESOPs to rely on their ERISA valuation.
- SOP 8.1 allows the cost of the valuation to be passed on to the buyer, and the funds the buyer spends count toward the equity injection.
- Quality of Earnings (QoE) Report - NEW
- SOP 8.1 in addition to a valuation, a QoE is required for Initial Acquisitions and Business Expansions with a business purchase price of $3M or more. It requires the QoE to be prepared for the lender (it cannot be prepared by or for the seller). A QoE the buyer commissioned may be used if one of the lender's approved vendors reviews it. The report must be prepared by an independent, experienced financial professional. Owner Buyouts, ESOP/Cooperatives, and acquisitions of owner-occupied Special Purpose Properties do not require a QoE.
- SOP 8.1 requires the report to include cash proof covering both the trailing 12 months and the last two fiscal years, document all add-backs, and assess customer concentration, contract continuity, and whether revenue and margins are likely to hold after the transaction. The scope may be reduced if the business has been operated for less than two years.
- SOP 8.1 requires the lender to use QoE adjusted earnings to calculate debt service coverage. If coverage falls short, the loan is reduced.
- SOP 8.1 the cost of the QoE may be passed on to the buyer, and the funds the buyer spends count toward the equity injection.
- Delegated Lenders
- SOP 8 allowed the valuation to be ordered after the SBA PLP number was issued.
- SOP 8.1 requires the valuation and any QoE to be formally engaged before the PLP number is issued.
- Business Purchase Price
- SOP 8 included all assets, including real estate, machinery and equipment, and intangible assets.
- SOP 8.1 excludes the appraised value of owner-occupied commercial real estate from the business purchase price. That adjusted price determines the financial due diligence requirements, including the $3M QoE threshold for Initial Acquisitions and Business Expansions, regardless of how the purchase is financed (equity injection, seller note, or other financing).
- Valuation Cap
- SOP 8 capped the loan proceeds used for the change of ownership at the valuation and required any extra financing to be subordinate to the loan.
- SOP 8.1 caps total transaction debt, including seller notes not on full standby, at the valuation. Any price above the valuation must be funded with equity injection or a seller note on full standby.
- Site Visit
- SOP 8 required a visit to the acquisition target for a complete change of ownership and complete partner buyout.
- SOP 8.1 requires the lender to conduct a site visit for both the buyer and the acquisition target. For e-commerce, virtual, or other non-customer-facing businesses, the lender may skip the physical visit if it documents why a visit would not improve verification and may instead use virtual meetings or a review of business records.
Underwriting
- Global Cash Flow
- SOP 8 required a global cash flow analysis, as applicable, on Standard 7(a) loans over $350,000 with at least 1:1 debt service coverage on a global basis. 7(a) Small loans and SBA Express loans were exempt.
- SOP 8.1 requires the lender to perform, as applicable, a global cash flow analysis on every change of ownership transaction, regardless of size, including 7(a) Small and SBA Express. It is also required when the lender adjusts owner’s compensation, which occurs in most transactions. The analysis must assess the impact of cash flow to and from any affiliate business and show at least 1.0x global debt service coverage.
- Debt Service Coverage (DSC)
- SOP 8 required 1.15x and it could be met with projections.
- SOP 8.1 requires 1.25x for Initial Acquisitions, Owner Buyouts, and ESOP/Cooperatives, and 1.15x for Business Expansions. Coverage is calculated as EBITDA divided by combined post-transaction debt service, and a global cash flow analysis of the buyer's personal and business obligations must show at least 1.0x.
- SOP 8.1 also requires coverage to be met on historical results (last fiscal year-end or 2-year average, historical or adjusted). Projections cannot be relied on, except for owner-occupied Special Purpose Properties (for example, hotels or self-storage) where the real estate fully secures the loan. In that case, the lender may rely on projections that meet the required DSC within two years of funding.
- Financial Statement Quality - NEW
- SOP 8 accepted three years of tax returns or financial statements plus an interim statement, without a required hierarchy.
- SOP 8.1 requires the lender to use the highest level available, in this order: audited, reviewed, compiled, then tax returns. It also requires comparable interim statements from the prior year.
- Interest-Only Transaction Debt - NEW
- SOP 8.1 debt that is interest-only and not on full standby must be underwritten at a 10-year amortization. This rule does not apply to lines of credit.
- Personal Financial Statements - NEW
- SOP 8 required buyer and guarantor personal financial statements to be dated within 120 days of submission to SBA.
- SOP 8.1 shortens this to 90 days (the SOP measures this from loan approval in the guaranty section and from submission to SBA in the application checklist). Buyers may need to update their Personal Financial Statement (SBA Form 413) if the process runs long.
Equity Injection
| Transaction Type | SOP 8 | SOP 8.1 |
| Complete change of ownership/ Initial Acquisition |
10% minimum | 10% minimum; cannot be reduced or eliminated |
| Business Expansion | No equity injection required in same 6-digit NAICS code, identical ownership, same geography, and businesses are co-borrowers | 10% in same 4-digit NAICS group; lender may reduce or waive if the buyer has sufficient liquidity and working capital and net worth is not negative |
| Complete partner buyout/ Owner Buyout | Equity injection only if the loan financed more than 90% of the price and either the 24-month participation test or the 9:1 debt-to-worth test was not met | 10% of the purchase price; lender may reduce or waive on the same conditions as Business Expansion |
| Partial change of ownership | Equity injection only if debt-to-worth exceeded 9:1 | Treated as an Owner Buyout (see above) |
| ESOP/Cooperative | ESOP: no equity injection required Cooperative: 10% minimum (treated as a complete change of ownership) | ESOP: no equity injection required Cooperative: 10%; cannot be reduced or waived |
- Waived Equity Injection - NEW
- SOP 8.1 if equity injection is waived for a Business Expansion or Owner Buyout, no dedicated permanent working capital can be added to this or any other 7(a) term loan within 90 days. Any working capital needed to support the transaction must come from existing cash or a line of credit. The lender may still disburse a small amount of excess proceeds as working capital for incidental adjustments, up to the greater of $10,000 or 0.5% of the loan.
- Equity Injection Sources
- SOP 8 equity injection could come from unborrowed cash, personal loans repaid from outside the business income, full-standby debt, grants with no clawback, independently appraised non-cash assets, verified prepaid expenses, or equity investments not subject to any agreement to repay or make distributions to the investor before the SBA guaranty is released. Seller notes counted only if on full standby for the life of the loan, and only up to half of the required injection.
- SOP 8.1 requires at least half of the required equity injection (5% at the 10% minimum) in every transaction type that requires an equity injection to come from unlimited sources: unborrowed cash, personal loans repaid from outside the business income and grants with no repayment, clawback, or similar provision for the entire term of the loan. Unborrowed cash can include a gift. Verified prepaid expenses are also an unlimited source. Unlike SOP 8, non-cash assets are no longer listed as an equity source, and fees for education, advisory services, or agents do not count as prepaid expenses.
- SOP 8.1 allows no more than half of the required equity injection to come from limited sources: full-standby seller notes, other standby debt, and non-controlling minority investors (under 20% and exerting no control).
- SOP 8.1 applies the same equity injection requirement to real estate bought with the business. When the real estate is financed with a separate loan, the equity injection is allocated pro rata between the two loans. If the real estate is financed with a 504 loan, the equity rules of the 504 program apply to that loan.
- SOP 8.1 allows the cost of the valuation and QoE to be passed on to the buyer, and the funds the buyer spends count toward the equity injection.
- Investor Rules - NEW
- SOP 8.0 addressed investor capital through a general rule: any investment, whether called search funding or anything else, that is subject to an agreement to repay the investor or make distributions to recover the investment before the guaranty is released is treated as debt, not equity.
- SOP 8.1 limits investors whose money counts toward required equity injections to distributions only to cover their taxes on the business income until the loan is repaid. Investments beyond the minimum equity injection may receive standard distributions subject to any lender covenants.
- SOP 8.1 prohibits anyone who provides standby debt counted toward the equity injection from taking an ownership stake in the business.
- Maturity
- SOP 8 allowed a blended term, or up to 25 years if 51% or more of proceeds went to real estate. For stock purchases, maturity could be based on the underlying assets financed.
- SOP 8.1 caps the business transaction portion at a 10-year amortization. All loans must state the amortization and maturity with no balloon payment. Exception: when an owner-occupied Special Purpose Property is integral to the business and 85% or more of total project costs are for real estate, the loan may have a maturity of up to 25 years.
- SOP 8.1 requires real estate to be financed as a separate loan or blended on a weighted average, with only the real estate portion allowed for up to 25 years.
- SOP 8.1 prohibits a 504 loan from being used on a blended basis.
- Accounts Receivable and Inventory
- SOP 8 left taking a lien on accounts receivable and inventory to the lender's discretion and counted no more than 10% of current book value toward the fully secured calculation.
- SOP 8.1 requires the lender to take a lien. The current book value security requirement remains the same.
- Companion Line of Credit - NEW
- SOP 8.1 allows a working capital line of credit to be opened alongside a 7(a) loan. The line can hold first lien on accounts receivable and inventory only if 20% to 50% of the line of credit day-one availability funds part of the purchase. These conditions do not apply to lines of credit in second lien position, such as SBA Express lines.
- SOP 8.1 businesses that need professional licenses to operate, such as med spas, electrical, HVAC, and plumbing are eligible for a loan only if the ownership structure meets state licensing requirements.
- SOP 8.1 in an Initial Acquisition and Business Expansion, the seller cannot remain an officer, director, stockholder, or employee. Because state licensing rules generally require the qualifier to be an officer or employee, in practice a seller who is the licensed qualifier cannot continue as the qualifier after closing, even during a 24-month consulting period. The buyer or another qualified individual will need to hold the license
- SOP 8.1 requires the lender to document that the business and its ownership structure meet state licensing requirements. If the buyer does not personally hold the license, expect the lender to ask how the business will stay legally operable, such as the buyer obtaining the license or a licensed employee serving as qualifier under a binding agreement.
- Key Employee Definition
- SOP 8 defined it as anyone hired to manage day-to-day operations.
- SOP 8.1 expands it to include an individual holding the experience, qualifications, or required license to run the business.
- SOP 8 and SOP 8.1 a lender may require any individual critical to the business, such as a Key Employee who holds the required license, to provide a full or limited personal guaranty. NOTE: SOP 8.1 does not specifically address requiring the buyer to hold the license, though a lender may make it a credit condition.
- Timing of Licensing Evidence (Unchanged, but Often Misunderstood)
- SOP 8 and SOP 8.1 requires the lender to obtain evidence of all licenses required to operate the business no later than 90 days after final disbursement and cannot sell the loan on the secondary market until all required licenses are obtained.
- SOP 8 and SOP 8.1 the 90-day window is an SBA documentation deadline, not permission to operate unlicensed. If state law requires the license on day one, it must be in place at closing, and many lenders make evidence of the license a condition of closing in their commitment letter or credit memorandum. Buyers should plan to have required licenses in hand at closing.

Buyers whose application SBA receives on or after October 1, 2026, must build their lending plan around SOP 8.1 requirements from the start rather than being surprised in underwriting.
