Debt-like items tax adjustments in an M&A transaction follow one governing principle: the party that actually pays the obligation, or bears its economic burden, is the party that gets the deduction. When the seller clears a liability at closing, the deduction reduces the seller’s gain on the sale. When the buyer assumes it, the deduction shifts to the buyer and is taken later, once the obligation is economically performed. Everything else, from Section 163(j) interest caps to 280G excess parachute payments to the 70/30 success-fee safe harbor, is a variation on that theme, and each variation changes how much the two sides are willing to move on price.
Which Obligations Trigger a Tax Adjustment
A debt-like item is any financial obligation that will drain future cash the way a loan would, even though no bank is involved: unfunded pension liabilities, deferred executive compensation, accrued employee bonuses, long-term litigation reserves, environmental cleanup costs, and capital lease obligations. Deferred revenue belongs on the list too. When a company has collected cash for services it hasn’t yet delivered, a cash-free, debt-free deal lets the seller walk with the cash and leaves the buyer with the delivery cost, so buyers routinely price that mismatch as a debt-like reduction or require a funded reserve.
Every dollar labeled debt-like comes straight off the purchase price. That is why classification is negotiated so hard: it moves both the headline number and, through the tax rules below, the ultimate after-tax economics for each side.
Who Deducts What, and When
The timing rule for accrual-basis taxpayers sits in IRC Section 461. A deduction cannot be taken until the underlying obligation is actually fulfilled. For a liability arising from services, the deduction waits until the services are performed. For a liability requiring payment, the deduction waits until the money goes out.1Office of the Law Revision Counsel. 26 U.S. Code 461 – General Rule for Taxable Year of Deduction The Treasury regulations put this in “all events test” language: the test isn’t met until economic performance occurs.2eCFR. 26 CFR 1.461-4 – Economic Performance
Applied to a deal, the rule sorts cleanly:
- Seller pays off the liability at closing. Seller takes the deduction, which reduces the seller’s taxable gain on the sale.
- Buyer assumes the liability. Buyer takes the deduction later, when it satisfies the obligation.
The complication for buyers is Section 163(j). If an assumed liability carries an implied interest component, the interest portion of the buyer’s future deduction is capped at the sum of business interest income, 30% of adjusted taxable income, and any floor plan financing interest.3Office of the Law Revision Counsel. 26 U.S. Code 163 – Interest A buyer expecting to write off a large assumed obligation in a single year may instead spread the deduction across several. That timing loss has value, and parties sometimes negotiate a tax benefit adjustment where the seller receives a portion of the future tax savings the buyer will realize. The exact percentage turns on discount rates, projected taxable income, and how quickly the buyer can actually use the deductions.
Pre-Closing Tax Liabilities
Unpaid taxes the seller owes for periods before closing form their own bucket of debt-like items. Common examples include income taxes accrued for the stub period before closing, sales and use taxes collected from customers but not remitted, and employment taxes (Social Security, Medicare, and income tax withholding) on wages earned through the closing date.
These amounts reduce the purchase price dollar for dollar. If the seller has collected $50,000 in sales tax and not sent it to the state, that full amount comes off the closing wire. The obligation arose from the seller’s operations, and the buyer needs the funds to actually pay the taxing authority. The adjustment also protects the buyer from liens and penalties the agency would otherwise pursue against the business, because tax authorities do not honor contractual assignments of responsibility.
Successor Liability and Personal Exposure
A purchase price adjustment is not a shield. Even in an asset purchase where the agreement excludes the seller’s liabilities, tax agencies can pursue the buyer as a successor if the buyer kept the seller’s employees, continued the same operations, or used the same location and branding. In a stock purchase, the risk is absolute. The buyer takes the entity and every obligation inside it, including payroll tax underpayments the seller never disclosed.
The personal exposure is what tends to get missed. Under IRC Section 6672, any person responsible for collecting and paying over employment taxes who willfully fails to do so faces a penalty equal to 100% of the unpaid trust fund taxes.4Office of the Law Revision Counsel. 26 U.S. Code 6672 – Failure To Collect and Pay Over Tax, or Attempt To Evade or Defeat Tax If a buyer’s officer or CFO becomes the responsible person after closing and later discovers withheld payroll taxes were never remitted, that individual can be personally on the hook for the full amount. Experienced buyers ask for state tax clearance certificates and review IRS Forms 941 and 940 during diligence rather than relying on the seller’s representations alone.
Golden Parachute Payments Under Section 280G
Change-of-control payments to executives and key employees create a distinct tax adjustment. When compensation tied to the deal exceeds three times the recipient’s base amount (their average annual pay over the five most recent tax years), the entire excess is treated as an excess parachute payment.5Office of the Law Revision Counsel. 26 U.S. Code 280G – Golden Parachute Payments The base amount is the individual’s average compensation includible in gross income over the base period, which is the five taxable years ending before the change in control.6eCFR. 26 CFR 1.280G-1 – Golden Parachute Payments
The consequences hit both sides. The company loses its tax deduction for the excess amount entirely. The individual owes a 20% excise tax on top of regular income taxes.7Office of the Law Revision Counsel. 26 U.S. Code 4999 – Golden Parachute Payments Buyers commonly treat the lost deduction, along with any gross-up obligation where the company has agreed to cover the executive’s excise tax, as a debt-like item that reduces the purchase price. A 280G analysis before the letter of intent is signed prevents a closing-table surprise. Privately held companies can sometimes exempt payments through a shareholder vote, but that vote must happen before the transaction closes.
Transaction Costs and the Success-Fee Safe Harbor
Legal fees, investment banking fees, and accounting costs incurred to close the deal generate a tax adjustment of their own. Treasury regulations require amounts paid to facilitate a covered transaction, including acquisitions of a trade or business, to be capitalized rather than deducted immediately.8eCFR. 26 CFR 1.263(a)-5 – Amounts Paid or Incurred To Facilitate an Acquisition Capitalization spreads the tax benefit over time instead of delivering an immediate write-off, and that is a worse result for whoever pays the fee.
Success-based fees, the kind investment bankers earn only when the deal closes, get preferential treatment under IRS Revenue Procedure 2011-29. If the taxpayer elects the safe harbor, 70% of the success-based fee is deductible as an expense that did not facilitate the transaction, and only the remaining 30% must be capitalized. The election requires a statement attached to the original tax return for the year the fee is paid, identifying the transaction and specifying the deducted and capitalized amounts. Once made, it is irrevocable for that transaction.9Internal Revenue Service. Revenue Procedure 2011-29
The dollar impact is real. A $2 million success fee produces a $1.4 million current deduction under the safe harbor versus none without it. The election is tied to the original return, not an amended one, so it belongs on the tax team’s checklist well ahead of the filing deadline.
Basis Step-Up Through a Section 338(h)(10) Election
A stock sale normally gives the buyer no step-up in the tax basis of the target’s assets. Asset values carry over, and future depreciation and amortization are lower than they would be after an asset purchase. A Section 338(h)(10) election changes that by treating the stock purchase as if the target had sold all its assets in a single transaction, so the assets are revalued to reflect the purchase price.10Office of the Law Revision Counsel. 26 U.S. Code 338 – Certain Stock Purchases Treated as Asset Acquisitions
The result is that asset write-ups and the intangibles identified in the purchase price allocation, including goodwill, become tax-deductible through depreciation and amortization. Goodwill and most acquired intangibles amortize over 15 years under Section 197.11Office of the Law Revision Counsel. 26 U.S. Code 197 – Amortization of Goodwill and Certain Other Intangibles The election requires both the buyer and the selling consolidated group to agree, and both must report the allocation to the IRS. The purchase price allocation follows the residual method in Section 1060, and the parties must file consistent allocations.12Office of the Law Revision Counsel. 26 U.S. Code 1060 – Special Allocation Rules for Certain Asset Acquisitions
The election only makes economic sense when the present value of the buyer’s future tax deductions exceeds the extra tax the seller pays on the deemed asset sale. Sellers usually demand compensation for that additional hit, and the number gets folded into the purchase price. This is the clearest illustration of how a tax adjustment shows up as a debt-like line: the tax cost is priced into the deal even though it is not a liability on any balance sheet.
How the Adjustments Actually Settle
Debt-like item numbers at closing are estimates. The purchase agreement sets a post-closing true-up window, commonly 60 to 120 days for the buyer to deliver a final adjustment statement based on closing-day financials, followed by a 15 to 30 day review period for the seller. Independent accountants resolve disputes under the methodology written into the agreement. The final settlement usually runs through an escrow account funded at closing.
For tax purposes, the true-up matters because it fixes the amount and, in some cases, the timing of the underlying deduction. If a debt-like reserve is reduced after closing, the party that eventually pays the smaller obligation is the one that deducts it. If it turns out larger, the deduction is bigger, but the party bearing the burden is still the party who claims it. Purchase agreements that leave the definitions of debt-like items vague tend to produce disputes not just over dollars but over which side gets to report the deduction, which is why the tax outcomes are best negotiated at the same time as the classification itself, not after.
