Refinance Business Debt With an SBA Loan: 6 Eligibility Rules

An SBA loan refinances only debt that did not need rescuing. That is the paradox built into the program: the government guaranty exists to help businesses that cannot find reasonable credit elsewhere, yet the rules for refinancing business debt are written to keep a lender from handing the SBA a loss it already knows about.

The rules sit in the SBA's Standard Operating Procedure for lenders, and they are in motion this autumn. SOP 50 10 8 governs through September 30, 2026. SOP 50 10 8.1, published September 25, 2026, takes effect on October 1, 2026 and changes the treatment of merchant cash advances, same institution debt, and seller notes. Both versions are on the SBA's SOP 50 10 page, and a lender underwriting an application this month should say which one it is applying.

1. The Old Debt Must Have Been Current for a Year

Under both versions, the debt to be refinanced must be, and must have been, current for at least the last 12 months, or for its entire term if that is shorter. "Current" has a precise meaning in the SOP: no required payment remained unpaid for more than 29 days. A single payment that ran 35 days late in March can disqualify a loan in September.

The same paragraph forbids using SBA proceeds to pay a creditor "in a position to sustain a loss," which includes any refinancing that would shift all or part of a potential loss from the original lender to the SBA. The two rules work together. A loan that is current but plainly impaired is still outside the program, because the question is whose loss the new loan would absorb.

2. The New Payment Must Fall by at Least Ten Percent

Borrowers often hear this described as a "substantial benefit" test. The phrase, if we are reading the SOP carefully, belongs to the 504 refinancing section; the 7(a) rule is stated as arithmetic. The new installment must be at least 10 percent less than the existing installment amount, and SOP 50 10 8.1 adds the words "in aggregate," which makes plain that a refinance of several debts is measured against their combined payments. For debts with escalating payments, the comparison uses the installment expected within the next 12 months.

Take a hypothetical business paying $9,000 a month across three term loans. To refinance them into one 7(a) loan, the new payment must come in at $8,100 or less. A structure that produces $8,300 fails the test regardless of how much the owner prefers a single lender.

Some debts are outside the ten percent comparison altogether. The SOP exempts debt with a demand note or balloon payment, business-purpose credit card and home equity line debt, and revolving lines the lender will not renew or that are being restructured for a lower rate or longer term. A balloon coming due next spring does not have to be beaten on payment size; it has to be replaced.

The ten percent rule is not a promise of savings. It is a floor for eligibility, and a lender can still decline on credit, cash flow, or appetite. Standard 7(a) underwriting also requires a debt service coverage ratio of at least 1.15 on a historical or projected basis, with the new SBA payment counted in the debt service, so a business that clears the payment test can still fail the coverage test (the two measure different things, one comparing the old payment to the new and the other comparing the business's operating cash flow, defined as EBITDA, to everything the business will owe once the new loan closes, and an owner who has only run the first calculation has run the easier one).

3. Same Institution Debt Carries Its Own Suspicion

When a bank proposes to refinance its own loan into an SBA-guaranteed loan, the SBA assumes the worst until the file proves otherwise. Under SOP 50 10 8, refinancing same institution debt may not be processed under a lender's delegated PLP authority, so it goes through non-delegated review. Under SOP 50 10 8.1, as of October 1, 2026, non-SBA same institution debt may be processed under PLP authority, but the lender may not use delegated authority to reduce its own credit exposure, may not refinance where there is an appearance that it will shift a potential loss to the SBA, and must document a 36 month payment transcript with a written explanation of any late payments.

Whether a bank ever offers this refinance to a borrower it is comfortable with, or only to one it is quietly worried about, is a question the SOP does not ask.

4. Merchant Cash Advances Change Status on October 1, 2026

Under SOP 50 10 8, the rule is flat: "Merchant cash advances and factoring agreements are not eligible for refinancing."

SOP 50 10 8.1 introduces a defined term, the Sales-Based Repayment Agreement, described as a business funding agreement in which the business receives a cash advance in exchange for a percentage of its future sales, with the merchant cash advance as the named example. Beginning October 1, 2026, such an agreement is eligible for refinancing only if three conditions are all met. The original agreement must have been converted to a term loan. It must have amortized for at least 24 months. And no additional agreements may have been implemented since the conversion. If the sales-based agreement is still active, it is not eligible. Factoring agreements remain ineligible.

Read closely, the new rule helps a narrow group of owners: those whose funder, at some point, rewrote the advance as a fixed-payment loan and who have since paid on it for two years without taking another advance. The typical stacked position, with daily debits still running and a second funder behind the first, is outside the rule both before and after October 1. The door opened by a few inches. There are owners for whom a few inches are enough, though in most stacked files the first funder never agreed to anything resembling a conversion.

An owner hoping to reach the 24 month line should also know that the payment history rule in the first section still applies to the converted loan, and that a new advance taken during those months resets the whole analysis.

5. The Lender Must Explain Why the Debt Exists

SBA assistance goes only to applicants for whom the desired credit is not otherwise available on reasonable terms from non-government sources, and the lender must certify or show that fact under 13 CFR 120.101. For a refinance, the SOP asks for more: a written analysis of why the debt was incurred, why the creditor is not in a position to sustain a loss, why restructuring is needed, and how the new loan improves the applicant's condition. Creditors being paid $10,000 or more must be itemized.

Two smaller rules catch owners who try to route around the analysis. Paying trade payables is not considered debt refinancing, and working capital proceeds may not be used to refinance existing debt. A refinance is to be declared as one.

6. Equity Injection Rarely Applies to a Straight Refinance

The SOP's minimum injections attach to start-ups in operation one year or less and to complete changes of ownership, each at no less than 10 percent of total project costs. An existing business refinancing its own debt faces no general injection figure in those passages; the lender instead judges whether the business has sufficient invested equity.

Seller notes are the exception worth noting. Under SOP 50 10 8 a seller note becomes refinanceable after 24 months in place and current, not on standby. Under SOP 50 10 8.1 the period is 36 months.

When the Rules Close the Door

An owner who reads this with a missed payment or an active advance already knows how the rules above treat those facts. That is not a verdict on the business. It means the path runs through settlement or restructuring first, and perhaps a conventional refinance later, once a clean payment history exists to show a lender.

Delancey Street works on that earlier stage. The company negotiates business debt, merchant cash advances above all; not a law firm, it brings in independently licensed attorneys where a matter needs legal work, and its first look at a file costs the owner nothing and stays confidential. The review can tell an owner which of the six rules the current file fails, and whether the obstacle is a matter of months, of arithmetic, or of structure.
