Anonymised, illustrative composite. The seller wanted credit for cash sales the tax returns had never seen. The buyer's lender was never going to lend against them, and admitting they existed was not a favour to the seller either.
At a glance
A buyer's letter of intent for an independent grocery store opened negotiations at a multiple of seller's discretionary earnings, using deavo's retail sector snapshot — a typical SDE multiple of 1.5–3.0×, published with deavo's disclaimer that its figures “are illustrative ranges based on comparable Canadian transactions, not a valuation, deal or investment opinion” — as the sector reference band, and 2.4× as the parties' own negotiated multiple inside it. The seller represented total SDE of $620,000. The store's filed corporate tax returns and financial statements, reviewed in diligence, supported $480,000 of that figure. The seller attributed the remaining $140,000 to cash sales that, in the seller's own words, “never made it into the till count.”
A buyer's valuator and a lender's underwriter both work from the same starting point: filed, verifiable financial statements, not an owner's own account of what the business really made. Income Tax Act s.230(1) (Records and books) requires every person carrying on business to keep records and books of account “in such form and containing such information as will enable the taxes payable under this Act… to be determined,” and s.230(4)(b) (Limitation period for keeping records, etc.) requires them to be retained “together with every account and voucher necessary to verify the information contained therein” for six years. Note which way that cuts: the obligation runs to the taxes payable, not to the taxes reported, so sales kept off the books are not merely unevidenced — keeping records that omit them is itself a failure of s.230(1). Revenue with no corresponding filing, and by definition no supporting voucher trail consistent with that filing, is not something a diligence team can substantiate, no matter how credible the seller's account sounds.
There was also a second-order problem the seller had not fully considered: admitting to $140,000 of undeclared annual cash sales is, in the same breath, an admission that income tax — and very likely GST/HST on those same sales — was underreported and underremitted. Excise Tax Act s.221(1) (Collection of tax) makes every person who makes a taxable supply an agent of the Crown for collecting the tax on it, so unremitted GST/HST on off-book grocery sales is a failure of a statutory collection duty, not an accounting oversight. That exposure belongs to the seller personally; it is not an asset a buyer can price or purchase.
Filed and verifiable SDE: $480,000 × 2.4× = $1,152,000. Seller's claimed SDE including unverifiable cash: $620,000 × 2.4× = $1,488,000. The gap between them — $336,000 — is exactly the value of the $140,000 the seller could not substantiate, at the same multiple applied to the rest of the business.
The buyer priced the deal at $1,152,000, on the filed $480,000 SDE, and declined to structure any portion of the price against the unverified $140,000 — not as a negotiating position, but because there was no basis on which a valuator or a lender could support crediting it. A vendor take-back note for the $336,000 gap was raised and rejected for the same reason a cash offer was: a note is only as good as the cash flow that repays it, and debt sized against unverifiable revenue carries the same underwriting problem as equity paid for it upfront — it does not solve the verification gap, it just relocates whose balance sheet it sits on.
Had the buyer's lender financed against the seller's claimed $620,000 SDE without reconciling it to filed returns and bank deposits, the resulting loan would have been sized to cash flow the business could not actually evidence, with real default risk once debt service came due against the true $480,000. A price paid at the higher figure, financed by any mix of debt, equity or a seller note, exposes whoever bears that portion of the deal to revenue that, on the seller's own record, does not exist for tax purposes.
There was a further cost the seller had not weighed: pressing the point risked drawing attention to the gap itself. Once a diligence team has heard a seller describe $140,000 a year of cash sales outside the books, that statement does not simply disappear if the deal falls through — it is the kind of thing that changes how carefully a buyer, or the next one, checks everything else the seller says.
The tell is a straightforward reconciliation: bank deposits, net of card settlement, run consistently and materially below what the point-of-sale system's own register totals over a sustained multi-month sample. That gap is checkable in an afternoon of bank statement review, well before a valuation or a financing package is built around a number the filings will not support.
A 30-minute call is enough to tell you whether a structuring or diligence gap like this one is sitting in your pipeline.
