SDE & Earnings

Which Add-Backs Are Legitimate in a Business Sale?

By Steve MorelloPublished August 18, 2026Reviewed August 18, 202610 min read

An add-back is legitimate when it removes a cost that will genuinely not exist for the buyer, is documented, and does not depend on an assumption about how the buyer will run the business. In practice that means four categories hold up reliably (interest, non-cash charges, one owner’s compensation in an SDE calculation, and normalization of related-party items to market), one holds up only with documentation (true one-time, non-recurring items), and one is challenged more often than not (discretionary and personal expenses).

Anything that adds back a cost the buyer will still incur, or that rests on a forecast, is not an add-back at all. This article gives the framework, a table of add-back types with their defensibility to a buyer and to an SBA lender, and an illustrative example of a broker’s SDE build surviving review.

What is an add-back, and why does it matter?

An add-back is an expense on the seller’s profit and loss statement that is added back to reported earnings on the theory that a buyer will not incur it. Add-backs are how a business reporting $180,000 of net income gets listed at $400,000 of seller’s discretionary earnings, and they are where most of the disagreement in a small-business sale lives, because every dollar added back raises the earnings base the price is quoted against and the cash flow a lender is asked to believe.

The stakes are simple. If a broker lists a business at $400,000 of SDE and a buyer or lender accepts only $340,000 of it, the price the buyer can justify and the loan the lender can approve both fall in proportion. The definitions of SDE and EBITDA, and how each treats add-backs, are covered in what is SDE and how is it different from EBITDA; this article is about which individual add-backs hold.

What makes an add-back legitimate?

Three tests, framed as practitioner judgment. An add-back is legitimate to the extent it passes all three:

  1. The cost will not exist for the buyer. Not “might not,” not “should not if the buyer is disciplined”: will not, because it was tied to the seller personally, was a one-time event, or was above or below market for a related-party reason that closing removes.
  2. It can be documented. Invoices, payroll records, contracts, bank statements, or the tax return itself. An add-back that lives only in the seller’s or broker’s explanation is an assertion.
  3. It does not depend on an assumption about the buyer. “You won’t need a second salesperson” or “you can cut marketing in half” are forecasts about the buyer’s operating decisions, not adjustments to the seller’s historical earnings. They belong in the buyer’s own model as risks, not in the earnings base as add-backs.

An SBA lender applies the same discipline in more formal terms. Under SBA SOP 50 10 8 (effective June 1, 2025, in force as of this article’s review date), the lender’s coverage analysis starts from EBITDA and must justify additions and subtractions to cash flow such as unfunded capital expenditures, non-recurring income, expenses and distributions, distributions for S-corporation taxes, rent payments, and owner’s draw. (Source: SBA SOP 50 10 8, Section B, Chapter 1, Underwriting Standard 7(a) Loans, Lender’s Credit Analysis, financial analysis of repayment ability.) Under SBA SOP 50 10 8.1 (effective October 1, 2026), the change-of-ownership rules list unfunded capital expenditures, non-recurring income, distributions, S-corp tax distributions, seller discretionary expenses, and ownership compensation as adjustments the lender may make, require the lender to state in the credit memo why each is prudent and supportable by ongoing operations, and provide that adjustments made without the lender’s supporting analysis are ineligible for the coverage determination. (Source: SBA SOP 50 10 8.1, Appendix 15, 7(a) Changes of Ownership, Adjusted Debt Service Coverage.) The lender must also verify the financials against IRS tax transcripts, so an add-back that only appears on an internal P&L and not on the filed return will not survive. (Source: SBA SOP 50 10 8.1, Appendix 15, financial reporting hierarchy and tax transcript verification; SBA SOP 50 10 8, Section B, Chapter 1, financial information requirements referencing Section A, Chapter 5.)

This is general information about SBA program rules, not advice for your specific transaction. Confirm the SOP version and your lender’s own credit policy with your lender.

Which categories of add-back hold up, and which get challenged?

Add-backs sort into six categories, and their defensibility follows the category. The table gives the type, typical examples, the documentation that supports each, and how a buyer and an SBA lender will generally treat it. The buyer and lender columns are practitioner judgment about what tends to survive review, not rules.

Add-back categories and their defensibility (practitioner judgment, not rules)
CategoryTypical examplesDocumentation that supports itBuyer's usual treatmentSBA lender's usual treatment
Interest and non-cash chargesInterest expense; depreciation; amortizationThe P&L and tax return themselvesAccepted; definitionalAccepted; EBITDA is the SOP starting point
One owner's compensation and benefitsSalary, payroll taxes, health insurance, retirement contribution, vehicle for one working ownerPayroll records, W-2 or K-1, benefit invoicesAccepted into SDE by definition; but the buyer then deducts replacement cost for any part of the role they will not performNot added back as such; ownership compensation is normalized with written justification, and the owner's compensation must cover their living expenses
Related-party normalization to marketRent paid to the owner's real-estate entity above or below market; a family member paid above market for the work done; a spouse on payroll who works and is paid below market (an adjustment down)Lease, market rent comparison, payroll records, job descriptionAccepted in either direction when the market figure is supportedAccepted with justification; rent adjustments are specifically contemplated
Genuinely non-recurring itemsLitigation settlement; storm or flood loss; a one-time consulting or systems project; a write-off tied to a discontinued lineInvoice or settlement agreement, dated, showing the item is not repeating across the years reviewedAccepted if documented and absent from other years; rejected if the "one-time" item recursAccepted with justification and documentation; recurrence across the historical period defeats it
Discretionary and personal expensesPersonal vehicle beyond one owner's; family members on payroll who do not work; personal travel, meals, and entertainment; personal insurance; charitable givingItem-by-item support: proof the person does not work, that the travel was personal, that the cost will ceasePartially accepted; each item is tested and many are discountedHeavily discounted; "seller discretionary expenses" is a permitted adjustment under 8.1 but only with the lender's supporting analysis, and lenders are conservative here
Assumption-based and aggressive items"Excess" staff the buyer will cut; marketing the buyer will reduce; growth or deferred-maintenance capex expensed as one-time; a second working owner's full compensation; projected synergies or price increasesNone that supports the historical figure; these are forecastsRejected as add-backs; considered, if at all, as upside in the buyer's own modelRejected; the SOP 8.1 test is historical or lender-adjusted, and projections may not be relied on to meet coverage

Two features of the table deserve emphasis. First, the owner-compensation row is legitimate in SDE and simultaneously the biggest reason SDE overstates lendable cash flow; the add-back is real, and so is the replacement cost that comes out afterward, which is worked through in does owner salary reduce SBA debt-service coverage. Second, the “assumption-based” row is where brokers and buyers most often disagree, and the disagreement is really about categories: those items are not adjustments to what the seller earned, they are bets on what the buyer will do, and a lender underwriting historical cash flow cannot count them.

What are the most common add-backs that fail review?

In practice, five patterns account for most of the add-backs that get struck:

  1. The recurring “one-time” expense. Repairs, legal fees, or bad-debt write-offs labeled non-recurring in the listing year that also appear in the two prior years. The three-year review a lender performs is designed to catch exactly this.
  2. The undocumented personal expense. “About $30,000 of personal spending runs through the business” with no schedule of what, when, or where. Without item-level support it is an assertion, and lenders discount assertions to zero.
  3. The family member who “doesn’t really work here.” A spouse or child on payroll whose compensation is added back on the seller’s say-so. If the person performs a function, someone will have to perform it after closing, and the compensation is not an add-back but at most a normalization to market.
  4. The second owner. SDE adds back one owner’s compensation. When two owners work full time and both salaries are added back, the buyer inherits a business that needs two people to run it and an earnings figure that assumes it needs none.
  5. The buyer’s future savings dressed as the seller’s past costs. “The new owner won’t need the outside bookkeeper” or “the marketing spend can be cut in half.” These may be true. They are also the buyer’s risk to take, not an adjustment to historical earnings, and they will not survive a lender’s historical or adjusted coverage test.

Illustrative example: a broker’s SDE build under review

All figures are illustrative and round. They are not typical results and not a projection for any deal. A broker lists a business at $500,000 of SDE, built from $260,000 of EBITDA plus the add-backs below. The buyer reviews each with documentation in hand and applies the framework above; the lender then applies its own, more conservative view for coverage purposes.

Illustrative add-back review: broker's claim, buyer's accepted amount, lender's accepted amount ($260,000 EBITDA base)
Add-back claimedBroker's amountBuyer's accepted amountLender's accepted amountReason
Owner salary and benefits (one owner)$125,000$125,000Normalized: owner compensation reset to a market $120,000 for the role, net effect $5,000Definitional in SDE; the lender normalizes rather than adds back
Spouse on payroll, "does not work in the business"$35,000$0$0Spouse handles bookkeeping and payroll two days a week; someone will have to
Rent paid to owner's LLC above market$18,000$18,000$18,000Lease and market comparison support the normalization
"One-time" equipment repairs$22,000$0$0Similar repairs appear in each of the prior two years
Litigation settlement$30,000$30,000$30,000Dated settlement agreement; no comparable item in other years
Personal vehicle, travel, and meals$10,000$6,000$3,000Vehicle documented; travel and meals only partly supported
Total SDE / adjusted cash flow$500,000$439,000Adjusted EBITDA about $316,000

The broker’s $500,000 becomes the buyer’s $439,000 of SDE after two add-backs are struck and one is trimmed. The lender’s figure is lower again, about $316,000, because the lender starts from EBITDA and normalizes the owner’s compensation to a market salary rather than adding it back, which is the SDE-versus-EBITDA distinction rather than a further add-back dispute. Same business, same P&L, three earnings figures, and the difference between the first and the last is the difference between the asking price and the loan.

How should a buyer handle add-backs before the LOI?

Framed as practitioner judgment: ask for the schedule of add-backs with documentation for each line before agreeing on price, not after. Sort each line into the categories above. Accept the definitional and documented ones, strike the assumption-based ones, and put the discretionary and personal ones through item-level review. Then build two figures: the SDE you accept, for comparing the listing to others and negotiating price, and the adjusted EBITDA the lender will compute, with a market salary for whoever will run the business, for deciding what the deal can support. The gap between the two figures is normal; the gap between the broker’s number and your accepted number is negotiation. What a lender does with that adjusted figure is worked in how is DSCR calculated when buying a business, and how to read the rest of the broker’s financials is in how to read a broker-prepared profit and loss.

For sellers, the same framework read in reverse is the preparation checklist: an add-back you can document and defend survives; one you cannot will be struck by every serious buyer and every lender, and it is better to remove it from the listing than to have it removed in diligence. The seller’s-side treatment is covered in what do buyers look for in quality of earnings.
