SBA Change-of-Ownership Rules Under SOP 50 10 8

Short answer: The rulebook for buying a business with SBA money tightened, and deals structured off last year's template now fail underwriting. Under SOP 50 10 8 as amended, every direct and indirect owner must be a U.S. citizen or national. Seller earnouts are prohibited outright. On a complete purchase the seller must fully exit, with at most a 12-month consulting transition. And a seller who keeps any equity co-signs your risk: a full guaranty of the entire loan for at least two years. None of this makes deals impossible. It changes how they have to be built, and the buyers who know the rules before the LOI write offers that close.

The citizenship gate comes first

Effective March 1, 2026, under SBA's updated citizenship and residency requirements, every direct and indirect owner of the borrower must be a U.S. citizen or U.S. national. Green-card holders are no longer eligible. The rule reaches everyone in the ownership chain, including a seller who keeps a minority stake, and it is binary: one non-qualifying owner makes the entire deal ineligible for SBA.

Check this before anything else, because no amount of structuring fixes it. A deal that fails the citizenship gate is not an SBA deal, and the financing plan moves to conventional debt, private credit, or heavier seller paper, the territory covered in financing a small acquisition.

Complete or partial, with no middle ground

SBA recognizes two shapes of purchase, and the seller's role after closing decides which rulebook you are in. On a complete change of ownership the seller divests entirely: no officer role, no board seat, no shares, no employment. The acquired business itself becomes a co-borrower, jointly liable on the note, and everyone owning 20 percent or more gives an unlimited personal guaranty.

A partial change, where the seller keeps equity, runs under stricter mechanics. It must be a stock or membership-unit purchase, never an asset deal. Every new owner taking any equity at all becomes a co-borrower. And the selling owner who retains a stake, even below 20 percent, must give a full guaranty of the entire loan for the later of two years or twelve consecutive months of current payments. The multi-step workaround, forming a new company with the seller to buy the operating company, is now expressly ineligible. If the plan is seller rollover, price those obligations into the negotiation, because there is no SBA structure where the seller keeps equity and walks away from the guaranty.

Earnouts are barred, and the workaround runs the other way

The correction that bites most buyers: seller earnouts are prohibited on an SBA complete change of ownership. An earnout pays the seller more if the business performs, which retains a seller interest, so it must come out of the purchase agreement entirely for the deal to be eligible.

The SOP allows the mirror image. A buyer rebate keyed to performance is permitted: the seller refunds part of the price if the business misses defined targets, a downward adjustment rather than seller upside, with the refund applied first to pay down the loan. So when a value gap needs bridging on an SBA deal, the instruments are price itself, a standby seller note, a holdback or escrow against the reps, or a forgivable seller note where a slice of the paper is forgiven if performance falls short. How the layers combine is the capital stack question. If the seller genuinely will not sign without a true earnout, the deal is telling you it is not an SBA deal, and it moves to conventional or private credit where earnouts are fair game.

The 12-month transition cap

The familiar plan where the seller stays eighteen months to hand off customer relationships does not survive SBA underwriting. On a complete change the seller may assist only as an independent consultant, paid a set hourly or monthly rate, for a maximum of 12 months from closing including every extension. No salary, no profit share, no retained control, and no disguised compensation like healthcare or a vehicle. If the business's value truly depends on the seller staying longer, that is a key-person risk to solve in diligence and structure: retain the seller's team, tie a holdback to client retention, negotiate a longer non-compete. Keeping the seller employed is not an available answer.

What this means for how you write the offer

Every rule above is knowable before the LOI, which means every one of them is a structuring input rather than a closing surprise. The buyers who lose deals to these rules are the ones who copied a purchase agreement from a non-SBA template and found out in underwriting. Screening the ownership chain, choosing complete versus partial, replacing the earnout with a compliant instrument, and sizing the transition is Deal Structure work, run before the offer goes out. The SOP moves, amendments landed twice in the last year, so your lender and counsel give the final word on the current text.
