When a small business is listed for sale, the advertised "cash flow" is rarely the net income on the tax return. It's net income plus add-backs — expenses the broker argues a new owner won't have. Some add-backs are legitimate and every lender credits them. Others are wishful thinking, and they matter enormously: since price is a multiple of earnings, every inflated add-back dollar gets multiplied into the price. Inflated add-backs are the #1 source of overpriced deals.
Here's each add-back category, from safest to most dangerous.
The always-credited add-backs
Owner salary. Whatever the current owner paid themselves through payroll gets added back, because it's part of the total economic benefit the business delivers to whoever owns it. This is usually the largest single add-back, and it's fully verifiable from the returns.
Depreciation and amortization (D&A). These are non-cash accounting entries — no dollar actually leaves the business — so they're always added back. (Just remember real equipment eventually needs real replacement; lenders may subtract a reserve for that later in the analysis.)
Interest. The seller's loan payments reflect their financing, not yours. You'll re-finance the business with your own capital stack, so their interest expense is added back and your own debt service is measured separately.
Taxes. Business income taxes are added back to reach pre-tax earnings — the standard basis on which multiples are quoted and coverage is tested.
The add-backs that need proof
Owner perks. The vehicle, travel, phone plan, and insurance the business paid but that really benefited the owner personally. Legitimate — but only what's documented counts. A line item on the return backs an add-back; a seller's verbal "oh, and about $30K of stuff runs through the business" does not.
One-time expenses. The lawsuit that settled, the cost of a move, the flood repair. Genuinely non-recurring costs deserve an add-back — but sellers have a way of discovering that many ordinary expenses were "one-time." Be conservative: if a category of "one-time" expense shows up more than once across the tax years, it's recurring.
Add-back confidence: the haircut
Lenders resolve this with a simple posture: they only credit what the tax returns and documents verify, and they haircut the rest. You should do the same. If the returns show $180K of net income and the listing claims $280K of owner benefit, the $100K gap is only as real as its paper trail — and the portion that isn't provable should be discounted before it ever touches the multiple.
This is also where your negotiating leverage lives. The spread between claimed earnings and verified earnings, times the industry multiple, is the amount the asking price may be inflated — a concrete, document-backed argument for a lower number.
Build the add-back schedule yourself
The free Deal Analyzer includes an add-back builder with a confidence slider: enter net income per the returns, add each category above, and dial back the credit on perks and one-time claims to match what the documents support. It shows claimed versus verified earnings side by side — the same discount your lender's underwriter will apply, visible before you write the offer. The outputs are estimates from your inputs, meant to inform a negotiation rather than replace due diligence.
