Your add-backs will be audited. Here is which ones survive.

Buyers multiply a recast number, not your tax return. On main street that base is seller’s discretionary earnings, which adds back one owner’s full pay. Once a paid management layer does the work, the base is adjusted EBITDA, which does not. Owner pay restated to market, personal expenses, related-party rent and singular items survive. Recurring costs relabeled one-time do not.

What earnings number does a buyer actually multiply?

A buyer multiplies a normalized earnings base, not reported net income. Two bases dominate deals this size. Seller’s discretionary earnings adds back one working owner’s entire compensation package. Adjusted EBITDA adds back interest, taxes, depreciation and amortization plus non-recurring items, but leaves a market-rate cost of management in the numbers. Quoting the wrong base against the wrong multiple destroys credibility.

The distinction is not cosmetic. Seller’s discretionary earnings assumes the acquirer steps into your chair and takes your pay. Adjusted EBITDA assumes the business already pays someone to sit there. Both descriptions can be honest.

Notice the last row. Hear a multiple quoted on adjusted EBITDA, apply it to seller’s discretionary earnings, and you have double-counted the same dollars and built a price that collapses in week one.

When does the base switch from seller’s discretionary earnings to adjusted EBITDA?

The crossover is functional, not a revenue line. Seller’s discretionary earnings remains the convention while one owner-operator genuinely does the selling, the estimating, the hiring and the collections. Adjusted EBITDA becomes the base once a paid management layer carries that work and you could leave without the schedule falling apart. Buyers test substance, not the org chart.

Ask about your own week. If you disappeared for ninety days, who quotes the jobs, who prices them, who holds the top three customer relationships? If the answer is a named employee on payroll, stop adding back your whole salary. If the answer is you, the buyer is pricing a job plus a business.

Segment matters. The published broker and advisor surveys covering transactions of this size report main street and the lower middle market separately, with different median multiples and different buyer pools. Know which set you sit in before you quote a multiple.

Market data: IBBA and M&A Source, Market Pulse Survey (Main Street and Lower Middle Market reported separately).

Why does the recast start at reported net income instead of the tax return total?

A defensible recast starts at reported net income for one year, then lists every adjustment on its own line with a source document behind it. The buyer prices the recast, not the return. Starting anywhere else, or presenting one summary number described as cash flow, forces the buyer’s accountant to build a competing version. That version will be lower.

Build the schedule so a stranger can walk it. Line item, amount, reason, proving document. One tab per year, three years side by side, and a reconciliation from each year’s net income to that year’s filed return.

That last item is not optional if your buyer is borrowing. Under the SBA standard operating procedure governing the 7(a) and 504 programs, a lender financing a change of ownership must obtain the financial information relied on by the person who performed the business valuation and verify it against the seller’s IRS transcripts. Numbers that cannot be tied to what you filed do not survive that check.

Lending rule: SBA SOP 50 10 8 (effective June 1, 2025), business valuation and lender verification for change-of-ownership loans.

How much is one add-back actually worth?

One defensible add-back is the highest-leverage line in a deal. Take an owner paid 100,000 dollars a year above market for the role. That excess is a legitimate normalizing adjustment to adjusted EBITDA. At a five times multiple, accepted by the buyer, it carries 500,000 dollars of enterprise value. Left as salary, it is one year of ordinary compensation income.

Treat the multiple as arithmetic, not a promise. Enterprise value is not proceeds. What the add-back changes is the base the buyer prices, and the character of the dollars.

Compensation is ordinary income and carries employment tax on both sides of the paycheck. Consideration allocated to goodwill and going-concern value is generally long-term capital gain where the asset was held more than a year, and carries no employment tax. As of August 2026 the maximum federal rate on long-term capital gain remains below the maximum federal rate on wages, and the 3.8 percent net investment income tax can apply on top, though gain from a business in which you materially participate is frequently outside it.

Three qualifications come first. If the selling entity is a C corporation, there is no preferential rate at the entity level and the conversion argument largely disappears. Consideration allocated to equipment can return as ordinary recapture. And you do not simply assert the goodwill figure: in an asset sale, consideration is allocated by the residual method and both sides report it. Several states grant no preferential rate, so confirm your state’s position as of August 2026.

Tax, stated as of August 2026: 26 U.S.C. 1(h) (capital gain rate structure); 26 U.S.C. 1411 (net investment income tax); 26 U.S.C. 3101, 3111, 1401 (employment and self-employment tax); 26 U.S.C. 1060 and Form 8594 (residual method allocation, reported by both parties).

Five hundred thousand dollars of price, from one line on a spreadsheet, and the character of those dollars changed with it. That line deserves a folder, not a footnote.

Which add-backs survive diligence, and which get struck?

Add-backs survive when they are documented, verifiable, and truly not a cost of running the business for the next owner. Owner compensation restated to a market benchmark, personal expenses run through the company, related-party rent restated to market, and genuinely non-recurring items generally hold. Recurring costs relabeled one-time, cut discretionary spending, deferred capital expenditures and buyer-created synergies get struck.

Law: 26 U.S.C. 162(a)(1) and 26 C.F.R. 1.162-7(b)(3) (like services, like enterprises, like circumstances); 26 U.S.C. 262(a) (personal, living and family expenses); 26 U.S.C. 162(a)(3) (rentals); 26 U.S.C. 482 (commonly controlled taxpayers).

One warning on the personal-expense line. Adding back spending you deducted is also a statement about the return you filed. Take it to your tax adviser before it reaches a schedule you hand a buyer. The same page can support a price and an indemnity claim.

What if I paid myself too little — do I owe the buyer a negative add-back?

Not as a legal duty, absent a representation you sign. But the buyer’s accountant will make the adjustment anyway. An owner who took 60,000 dollars while a manager doing that job costs 150,000 dollars has understated the cost of running the business by 90,000 dollars. Adjusted EBITDA comes down by that gap.

Owners resist this line hardest, and resisting it is expensive. The benchmark that supports your positive add-backs produces the negative one. An accountant who catches you arguing market compensation in one direction only discounts every other line.

A second exposure hides in the same facts. Generally, an officer of a corporation who performs more than minor services is an employee for employment tax purposes, and where an S corporation pays a shareholder-officer distributions instead of wages, those amounts are treated as wages to the extent they are reasonable compensation for services rendered. Chronic under-salarying is a tax position, stated here as of August 2026, not merely a valuation input. Buyers ask, and the answer sometimes travels into an indemnity or a holdback.

How will the buyer’s accountant attack my numbers?

A quality-of-earnings review is an accountant’s reconstruction of your earnings from source data. On the smallest deals a formal report is uncommon; the same work gets done by the buyer’s own accountant and by the lender’s credit file. Either way, four moves account for most findings, and each is detectable from documents you already hold.

• Changed accounting policy. A reserve method, an inventory convention or a cutoff practice that changed in the year you decided to sell. The reviewer compares years on a consistent basis, so the change adds nothing. Changing a tax accounting method also requires the Secretary’s consent (26 U.S.C. 446(e)), which makes it visible on the returns.
• Aggressive revenue recognition. Invoicing ahead of delivery, recognizing deposits as revenue, pulling January work into December. Testing is simple: match invoices to shipping documents, work orders and cash receipts.
• Cost deferred onto the balance sheet. Expenses parked in inventory, prepaids, work in process or fixed assets. The reviewer traces the additions and asks what was capitalized.
• One-time items that recur. The same category adjusted in each of three years. That is a cost of doing business with a different label.

Where an accounting question ends up in dispute after closing, the answer depends on your purchase agreement, not on a market default. Lower middle market agreements often send post-closing adjustment disputes to an independent accountant applying GAAP. Smaller deals frequently carry no adjustment mechanism at all, and a fixed price leaves nothing for an accountant to decide. Read the clause, and do not assume the expert is the last word. In a 2025 Delaware Court of Chancery decision the court reviewed the scope of the expert’s authority itself, held GAAP took precedence over consistency with historical practice on the disputed items, and routed representation and warranty questions to indemnification.

Case law: Northern Data AG v. Riot Platforms, Inc. (Del. Ch. June 2, 2025). Delaware law applies only where the agreement selects it.

Financing has tightened. Under the revised SBA standard operating procedure issued August 14, 2026, 7(a) change-of-ownership lending moves into a dedicated appendix, and the new requirements apply to loans receiving an SBA loan number on or after October 1, 2026. A lender-ordered quality of earnings report is required where the business purchase price is 3 million dollars or more. The debt service coverage floor rises to 1.25 times for first-time acquisitions and owner buyouts, while same-industry expansions stay at 1.15 times. If your likely buyer borrows, assume a third-party accountant reads your schedule line by line.

Lending rule: SBA SOP 50 10 8.1, Appendix 15 (issued August 14, 2026; applies to loans numbered on or after October 1, 2026).

An add-back the buyer cannot verify is not an add-back. It is a request. Requests get declined in diligence, and they take the credible lines down with them.

What should I do in the next thirty days to make my add-backs stick?

Build the add-back schedule before any buyer asks for it. A schedule prepared under deal pressure looks like advocacy. The same schedule prepared in advance, with documentation filed behind each line, looks like bookkeeping. Buyers concede documented lines and attack undocumented ones, and the gap between those outcomes is measured in multiples.

Concrete steps, in order:

• Pick your base and write one paragraph on who does the work.
• Pull three years of ledger detail and tag every personal or non-operating item at the transaction level, not by category.
• Get a written compensation benchmark for your own role, and accept the answer in whichever direction it goes.
• Get a written market rent opinion if you or a related entity owns the real estate.
• Assemble the proof file for each non-recurring item: engagement letter, settlement agreement, insurance claim, invoice.
• Reconcile each year of the recast to the return you filed, and keep the reconciliation with the schedule.
• Strike your own weak lines first: deferred capital expenditures, cut marketing, anything you would be embarrassed to defend twice.

Then have deal counsel and your accountant test the schedule adversarially before it leaves your office. The purpose is not more add-backs. It is that every line survives.
