Build SDE from the records, not from a list

SDE is a subtotal with a boundary

Seller's discretionary earnings (SDE) is a business-brokerage earnings measure before income taxes, interest, depreciation and amortization, nonoperating and nonrecurring items, and one owner's entire compensation, benefits, and business-paid personal expenses. It is not cash available for any purpose, a valuation, or proof that a buyer will accept an adjustment. ¹

The words “before” and “one owner” do most of the work. They define which categories the schedule is trying to expose. IBBA separately defines owner total compensation as salary and perquisites after the compensation of other owners has been adjusted to market value. Adding every owner's pay without a role analysis would change the definition. ¹

SDE also does not equal cash flow. The subtotal does not automatically account for capital spending, working-capital changes, principal payments, distributions, or transaction expenses. Those belong in their own records and bridges. Calling the result “cash to the owner” would hide obligations that sit outside this calculation.

Use the number only with its workpaper. A naked subtotal cannot reveal the source period, sign convention, mixed accounts, omitted offsets, or disputed rows. The goal is not to make earnings look larger. It is to make the path from recorded profit to the stated measure inspectable.

Entity form changes where the bridge begins

Start by writing four facts above the schedule: legal entity, source document, accounting basis, and period. Then name the exact starting line. Do not switch from a tax return to an internal trailing-period statement halfway through the bridge without a separate reconciliation.

A 2025 Schedule C reports sole-proprietorship net profit on line 31 and contains no dedicated officer-compensation line. The 2025 Form 1120-S instructions, by contrast, place officer compensation on line 7 and other salaries and wages on line 8. Those forms do not calculate SDE, but they show why the source map cannot be copied blindly. ²³

If the owner begins with Schedule C net profit, there may be no recorded owner wage to add back. If an S corporation owner begins with page-one ordinary business income, officer compensation may already reduce that amount. The workpaper should show the actual return line, payroll report, and ledger account rather than assuming the entity label answers the question.

Internal statements create another control. Tie the starting subtotal to the general ledger and explain any tax-to-book, cash-to-accrual, or period conversion on separate rows. A single “per tax return” note is not enough when the working schedule uses later months or different classifications.

This mapping is not tax advice. Tax treatment follows the applicable law, form, entity, and facts. The narrower seller lesson is that the recorded location of owner economics changes, so the same amount can be missing, duplicated, or assigned the wrong sign when a template ignores the source architecture.

Give every adjustment eight fields

Calculate SDE as a controlled reconciliation, not a memorized formula. Preserve one untouched source statement, identify its entity and period, and list each proposed adjustment on a separate row with its sign, ledger account, supporting document, business purpose, recurrence, related offset, and status.

Recalculate from the source and back from the subtotal; unresolved rows remain visible rather than being treated as accepted. ¹²³⁴

The ledger account proves where the amount was recorded. The invoice, payroll report, agreement, asset schedule, or receipt helps explain what produced it. IRS Publication 583 identifies invoices, receipts, account statements, payroll records, journals, and ledgers as supporting business records and calls for bank-account reconciliation. Its tax context does not decide transaction treatment. ⁴

Split mixed accounts before evaluating them. If a vehicle account contains business use and an owner-specific portion, place only the documented owner-specific portion on the proposed row. Preserve the untouched account total and the allocation support. The same rule applies to travel, insurance, family payroll, memberships, and shared facilities.

Give each line one status: proposed, supported, unresolved, removed, or accepted for the stated use. “Supported” means the amount and rationale have records. It does not mean a buyer, lender, accountant, tax adviser, or valuation professional agrees with the treatment. Keep status changes dated and never overwrite the original proposal.

• Source statement line and ledger account
• Signed amount and exact measurement period
• Invoice payroll report schedule agreement or receipt
• Business purpose and owner-specific portion
• Recurrence explanation and next known occurrence
• Related income cost reimbursement or insurance offset
• Prepared-by owner and date
• Proposed supported unresolved removed or accepted status

A fictional reconciliation shows where schedules break

Hypothetical example — not market evidence, buyer treatment, a forecast, or a valuation. Cedar Line Repair is fictional. Every amount, account, support note, status, and result below was created only to demonstrate the control sheet.

The fictional internal income statement shows net income of $312,000 for the twelve months ended June 30. The schedule adds $24,000 of interest, $8,000 of income taxes, and $38,000 of depreciation and amortization. These three rows tie to a debt schedule, tax account detail, and fixed-asset schedules in the fictional file.

The workpaper then adds $160,000 of one working owner's payroll and payroll taxes plus $18,000 of separately recorded owner benefits. It does not add the benefits twice. The payroll register and benefit invoices are separate supports, and the line descriptions state exactly which owner is covered. ¹

A $14,000 vehicle account contains a fictional $6,000 owner-specific portion. Only that portion is proposed. A $12,000 relocation expense is paired with a $5,000 insurance recovery from the same fictional event, so the schedule adds the cost and subtracts the recovery on separate rows. Hiding the offset would overstate the subtotal.

The arithmetic reaches $573,000: $312,000 + $24,000 + $8,000 + $38,000 + $160,000 + $18,000 + $6,000 + $12,000 − $5,000. That total proves only that the rows sum. It does not establish that a transaction counterparty will accept the proposed owner-specific or nonrecurring treatment.

Cross-foot the schedule in reverse. Begin at $573,000 and undo each signed line until the workpaper returns to $312,000. Then compare the listed records with the general ledger and untouched statement. A failed reverse bridge usually points to a duplicate, sign error, mixed-period line, or hidden offset.

Test the record before debating the label

A proposed line needs two different proofs: amount and treatment. A ledger export may prove that $14,000 was recorded to vehicles, but it does not prove the owner-specific portion. An invoice may prove a relocation cost, but it does not prove that the event is nonrecurring or that related recovery income was captured.

Current IVS includes explicit standards for Data and Inputs and Documentation. The public summary does not define SDE, yet the control applies cleanly: retain the source, show the transformation, state the assumption, and preserve the limitation. A subtotal without lineage is difficult to review or reproduce. ⁵

For recurrence, write the event and the counterfactual. What happened, what caused the line, what related entries exist, and what cost would remain under continuing operations? “One-time” is not an explanation. Neither is “personal” when the account also supported business use.

Apply the same discipline to downward adjustments. Nonoperating income, insurance proceeds, refunded expenses, an omitted operating cost, or a below-market expense can reduce the selected subtotal. A schedule that searches only for positive lines is not a reconciliation; it is an advocacy document.

Preserve uncertainty in the status column. If the amount ties but recurrence is unresolved, mark it unresolved. If only part of the account has support, split the supported and unsupported portions. This makes the next review faster because disagreement is attached to one row rather than buried in a new total.

Do not hide the owner's job inside the add-back

The stated SDE definition includes one owner's entire compensation and benefits. That does not make the owner's labor free. Record the SDE subtotal first, then build a separate owner-role map showing duties, time, seasonality, required credentials, relationship coverage, and existing backup. ¹

Form 1120-S tax instructions say officer payments must be treated as wages to the extent they are reasonable compensation for services. AICPA's current valuation resource separately emphasizes role definition, assumptions, data selection, consistency, and defensibility when compensation is material. Neither source supplies a fixed transaction replacement cost. ³⁶

This separation matters for more than one owner. Under the cited IBBA owner-compensation definition, other owners' compensation is adjusted to market value before one owner's total compensation is considered. Identify each person's recorded pay and work rather than adding all owner-related payroll because the names appear on an ownership list. ¹

Keep tax reasonable compensation, SDE reconciliation, and future operating cost as three labeled workstreams. They may use overlapping payroll and duty records, but they answer different questions. Combining them can create an internally consistent spreadsheet that is wrong for the intended decision.

When the role map is complete, move to the SDE-versus-EBITDA guide. That page owns whether an owner-operator subtotal or a managed-company subtotal fits the discussion. This page stops at a traceable SDE schedule and does not prescribe a denominator.

Continue to the earnings-basis comparison to compare SDE with EBITDA after the owner role is mappedrather than choosing a denominator from company size.

Hand off a schedule that can survive a question

Save three versions: the untouched source records, the proposed workpaper, and the current disposition copy. Lock formulas and use a change log for amount, sign, evidence, or status revisions. A reviewer should be able to reproduce the subtotal without asking which tab or email contains the missing fact.

Roll the schedule across at least the periods actually used in the valuation discussion. Do not splice a trailing revenue period to prior-year expenses without a visible bridge. A period change may alter owner compensation, insurance recoveries, depreciation, or nonrecurring-event treatment even when the account names stay the same.

Use the earnings-quality guide to test adjustment evidence under diligence and the valuation-method guide to keep an earnings input separate from a value conclusion. Return to the valuation department when the source period, definition, and outstanding rows are clear.

With the source period and open rows visible return to the private-company valuation departmentto place SDE inside the broader decision.

The private valuation path can use organized inputs without treating them as verified merely because they were entered. Keep invoices, payroll, tax returns, and account-level detail in a controlled deal file. The public intake does not need sensitive source documents to frame the first conversation.

Use the organized schedule to continue to the confidential valuation pathwithout treating entered data as automatically verified.

Or use the confidential intake to frame a private owner conversationwithout sending source documents through the public page.

A useful SDE schedule makes objections cheap to locate. It shows the untouched starting point, every signed change, the record behind it, the question that remains, and the current status. Confidence should come from that audit trail—not from a larger subtotal or a longer list of add-backs.
