Add-Back
An add-back is an adjustment made when recasting a business's financial statements that restores a reported expense to earnings because the expense is discretionary, non-recurring, or will not continue under new ownership, such as the owner's salary, a personal vehicle lease, a one-time legal settlement, or non-cash depreciation. Each add-back raises SDE or Adjusted EBITDA dollar for dollar, so at a 3.5x multiple an accepted $20,000 add-back is worth $70,000 of purchase price and a rejected one costs the seller the same amount.

What a buyer does to a schedule of add-backs
Add-backs are the most heavily negotiated numbers in a small-business sale, because every dollar of them is multiplied. A specialty contractor priced at 3.5x SDE submitted $384,400 of proposed add-backs. The buyer's response, line by line:
- Owner's W-2 salary, $180,000 — accepted in full
- Owner's health insurance, retirement match and the payroll taxes on the owner's own wages, $34,200 — accepted
- Owner's truck lease, fuel and insurance, $16,800 — accepted
- Travel and meals coded to the business, $12,400 — half accepted, because $6,200 was documented client entertainment that continues after closing
- Legal fees for a one-time partner buyout, $41,000 — accepted, with the settlement agreement attached
- Consulting fees paid to a relative of the owner with no deliverable and no successor arrangement, $30,000 — accepted
- Marketing and advertising the seller calls discretionary, $22,000 — struck, because it produced the pipeline the buyer is paying for
- A one-time equipment overhaul, $48,000 — struck, because the same line ran $39,000 and $44,000 in the two prior years, which makes it a recurring cost with a variable amount rather than a one-time event. At most the increment above that run rate is arguable, and this buyer did not concede it.
Accepted add-backs come to $308,200. The $76,200 the buyer disallowed costs $266,700 of purchase price at 3.5x — and the two struck lines cost more than their own value, because a buyer who strikes two lines starts re-reading the other six.
Note that one line was neither accepted nor struck. Partial acceptance is the normal outcome for mixed-use categories such as travel, meals, vehicles and phones. A seller who splits those lines before submitting them usually keeps more of the total than one who submits the gross figure and leaves the splitting to the buyer.
The three tests a buyer applies
Every proposed add-back gets run through the same three questions, in order, and has to clear all three.
Is it real? The expense must actually appear in the reported figures. An expense the business never recorded cannot be added back, and the same dollar cannot be added back twice under two labels — which happens more often than sellers expect when owner benefits are spread across several accounts.
Will it not continue? This is the substantive test. Depreciation is non-cash and clears easily. A one-time legal settlement clears if it is genuinely one time. A club membership clears if the buyer will drop it and the customers will stay. Rent paid to the owner's own LLC clears only up to the variance against market rent, which requires an actual market rent figure rather than an assertion.
Can you prove it? An add-back with no supporting document is worth nothing in diligence regardless of how true it is. The proof standard tightens as the deal progresses: a buyer will take a seller's schedule at face value at the letter of intent stage and will not take it during quality of earnings.
Proof each category needs
Matching evidence to category before a buyer asks is the cheapest work in a deal.
Non-recurring is the category tested hardest, because the label is the claim. An expense described as one-time that appears in two of the three recast years is not one-time; it is a recurring cost with a variable amount. See one-time expense.
- Owner compensation: W-2 or K-1, payroll register, and a market-rate reference for the role if the adjustment is stated as an excess above market
- Owner benefits: the insurance invoice, the vehicle lease agreement, the membership statement
- Personal expenses in a business account: general ledger detail with the individual transactions identified, not a percentage allocation
- One-time expenses: the invoice, settlement agreement or project contract, plus the prior two years showing the expense absent
- Related-party rent or fees: the lease or agreement plus a market comparison — see related-party transaction
- Depreciation, amortization and interest: the Form 4562 depreciation schedule and the loan documents, which is why these are the least contested add-backs in any recast
Add-back, reclassification, or pro forma
Three adjustments look similar on a schedule and are treated very differently by a buyer.
An add-back restores a recorded expense to earnings because the expense will not continue. A reclassification moves an amount between categories without changing the bottom line, for example moving equipment financing interest out of operating expenses so EBITDA is comparable to other companies. A pro forma adjustment models something that did not happen in the reported period at all, such as a full year of revenue from a customer won in month nine.
Only the first two describe what actually occurred. Pro forma adjustments have a legitimate place in a sale package but belong in their own clearly labelled schedule; a buyer who finds one hiding among the add-backs will discount the entire file. See recasting for how the schedules are kept separate.
One further boundary is worth stating plainly: an add-back is not a way to recover an expense the seller regrets. Money spent on a failed product line was really spent, and unless the line is closed and its costs are demonstrably gone, the expense stays in the base. The test is what the business will cost to run next year, not what the seller wishes it had cost last year.
Where this shows up in CastBack
CastBack adds back depreciation, amortization and interest expense automatically, never auto-applies owner compensation or income tax, surfaces discretionary-looking operating expenses as suggestions the broker has to confirm, and keeps every add-back decision with its plain-language reason in a deal-level audit trail.
