The purchase price on your offer sheet looks like a number. The after-tax wire in your account is a different number, often tens or hundreds of thousands of dollars smaller. The gap between those two figures is called purchase price allocation, and how it is negotiated before you sign the purchase agreement determines which tax rate applies to every dollar of your deal proceeds.
Most business owners learn about purchase price allocation the week before closing. That is too late. By then, the buyer has the leverage and you are reading schedules that were written to benefit them.
What purchase price allocation is
When a business sells in an asset transaction, the IRS does not recognize "business value" as a single tax category. It requires both the buyer and the seller to allocate the total purchase price across seven classes of assets, each taxed differently. Both parties file Form 8594 (Asset Acquisition Statement Under Section 1060) with their tax returns for the year of sale. Both filings must match. If they do not, both returns become audit targets.
The seven classes, in order:
- Class I: Cash and bank deposits. No gain at face value.
- Class II: Actively traded securities. Generally capital gain.
- Class III: Accounts receivable. Ordinary income on amounts above basis.
- Class IV: Inventory. Ordinary income at rates up to 37%.
- Class V: Tangible property (equipment, vehicles, furniture, real estate). Depreciation recapture at ordinary income rates; gain above original cost at capital gains rates.
- Class VI: Section 197 intangibles except goodwill (non-compete agreements, customer lists, licenses). Ordinary income for non-competes; capital gain for others.
- Class VII: Goodwill and going-concern value. Long-term capital gain, the most favorable rate.
The IRS uses the residual method: it assigns value to each class in order from I through VI, and whatever purchase price remains becomes Class VII goodwill. This matters because the buyer and seller rarely want the same result.
Where the conflict lives
Purchase price allocation is zero-sum. Any tax benefit one party captures comes at the other's expense.
The buyer wants allocations in Class V (equipment) and Class VI (identified intangibles). Equipment depreciates over five to seven years. With Section 179 and bonus depreciation, a buyer can write off the entire equipment value in year one. Non-competes and customer lists amortize over 15 years under Section 197. Either way, the buyer gets a faster tax deduction stream than waiting 15 years on Class VII goodwill.
The seller wants the opposite. More in Class VII means capital gains treatment at 23.8% (20% federal rate plus 3.8% net investment income tax for high earners). More in Class V means depreciation recapture. If you bought equipment for $800,000, depreciated it to zero, and the buyer's appraisal values it at $600,000, you owe ordinary income tax on the full $600,000. At a combined federal and state rate near 42%, that is a $252,000 tax bill on equipment alone, before any capital gains taxes on the rest of the deal.
Non-competes are the specific trap that catches sellers late in the process. A buyer who allocates $500,000 to a non-compete agreement (Class VI, ordinary income) instead of goodwill (Class VII, capital gain) shifts the seller from a 23.8% rate to 37% on that $500,000. The cost of that single allocation: $66,500 in additional federal tax. Most sellers do not notice until the CPA runs the closing tax model.
What the numbers actually show
On a $5 million deal with $2 million of purchase price shifted from equipment to goodwill, the estimated tax difference exceeds $400,000, according to Acquisition Stars' 2026 analysis. On a $15 million deal, the gap between an asset sale and a stock sale, driven substantially by allocation decisions, runs $500,000 to $1.5 million.
CT Acquisitions puts the range directly: sophisticated sellers can save 5 to 25% of net tax through allocation discipline. On a $5 million transaction, 5% is $250,000 in after-tax proceeds. That is not a rounding error. It is a negotiating point worth more than most of the legal fees paid on the deal.
Stock sale vs. asset sale: how PPA fits in
In a stock sale, purchase price allocation does not apply the same way. The seller's gain calculates on their stock basis and is typically long-term capital gain at 23.8%. The buyer takes the company with the existing (low) asset basis and gets no depreciation step-up. That is why PE firms and search fund buyers default to asset deals: the step-up in basis is worth $200,000 to $800,000 in present-value tax deductions on a typical lower-middle-market acquisition.
If you own an S-corporation, the Section 338(h)(10) election is worth understanding. When a buyer acquires at least 80% of your stock, this election treats the transaction as an asset purchase for tax purposes while keeping the legal form of a stock sale. The buyer gets the step-up. You get single-level taxation instead of the double taxation that hits C-corps in asset sales. Both parties file the election jointly. This is the most common mechanism for resolving the asset-versus-stock tension in S-corp acquisitions at the lower middle market level.
For C-corp founders, personal goodwill is the other mechanism worth modeling. If the business value rests substantially on your individual customer relationships, technical expertise, or reputation rather than on systems the company controls, that goodwill may legally belong to you as an individual, not to the corporation. Proceeds from personal goodwill are taxed at individual capital gains rates with no corporate-level tax. The Tax Court established this in Martin Ice Cream Co. v. Commissioner (1998) and the doctrine has not changed. On a $30 million C-corp transaction, Miller Cooper estimates personal goodwill planning can reduce the tax burden by $1.5 million or more. Documentation must be prepared before the LOI, not at closing.
When in the deal process allocation is negotiated
Most lower-middle-market letters of intent are silent on allocation. The purchase agreement addresses it. That sequence is backward from the seller's interest.
Once you have signed the LOI, your ability to walk away from the deal has cost you months of work, legal fees, and management distraction. The buyer knows this. Pushing for allocation terms you did not establish in the LOI means pushing from weakness.
The practical sequence: engage a CPA with transaction experience before you receive the first offer. Have them model three allocation scenarios (buyer-favorable, neutral, seller-favorable) with after-tax proceeds on each. Know your number before you sign anything. If the LOI is already in front of you, at minimum require that allocation methodology be addressed in the definitive purchase agreement with a worksheet signed by both parties' CPAs at closing.
One requirement is non-negotiable: both Forms 8594 must match. Inconsistent filings between buyer and seller are a direct IRS audit trigger. The only way to guarantee consistency is to have both tax advisors sign off on a shared schedule before the closing date.
What to prepare before the LOI
Pull your depreciation schedules now. Know the adjusted tax basis of every piece of equipment. Surprise recapture bills at closing run $200,000 to $2 million for equipment-heavy businesses. That number is not a surprise if you calculate it before the process starts.
Engage a CPA who has done M&A deal tax work, not just annual returns. The difference between a CPA who knows Section 1060 and one who does not is measured in six figures on a $5 million deal.
Understand that the asset-versus-stock sale structure decision comes before allocation. Structure determines which tax rules apply. Allocation optimizes within that structure. Getting structure wrong makes allocation discipline irrelevant.
Research personal goodwill if your business value is personal to you. If customers buy because of your relationships, your technical skill, or your reputation, those may be assets the IRS treats as belonging to you individually, not your company. Asserting personal goodwill requires documentation and an independent valuation, prepared before the LOI, not at closing. Get a tax attorney familiar with Martin Ice Cream Co. and the Section 197 rules on the phone early.
The allocation table determines the final number
The purchase price you negotiate is the headline. The allocation you accept is the deal.
Buyers who have closed dozens of transactions know every lever in that table. Most sellers do it once. The preparation gap shows in the after-tax wire. A veteran-founded PE firm that acquires your business has CPAs who have run these allocation models hundreds of times. Your counter is to run them yourself, before you sign the first document, not while sitting at the closing table reading schedules you have never seen before.
You spent years building the business. The allocation discussion takes two weeks to prepare for. That preparation pays better than almost anything else you do in the exit process.
Frequently Asked Questions
What is purchase price allocation and why does it affect your after-tax proceeds?
In an asset transaction, the IRS requires both buyer and seller to allocate the total purchase price across seven classes of assets, each taxed at different rates. The allocation determines which tax rate applies to every dollar of deal proceeds, and the gap between the headline price and the after-tax wire can be tens or hundreds of thousands of dollars.
Which asset class carries the most favorable tax treatment for sellers?
Class VII, goodwill and going-concern value, is taxed as long-term capital gain, the most favorable rate. Both buyer and seller typically want opposite outcomes: buyers prefer allocations to equipment and identified intangibles for faster depreciation, while sellers benefit from more value in Class VII.
Why are non-compete allocations described as a specific trap for sellers?
A buyer who allocates value to a non-compete agreement, which is Class VI taxed as ordinary income, instead of goodwill in Class VII shifts the seller from a capital gains rate to a higher ordinary income rate on that amount. On a 500,000 dollar non-compete allocation, that single shift costs the seller an estimated 66,500 dollars in additional federal tax.
When in the deal process should a seller engage a CPA on allocation strategy?
Before receiving the first offer. A CPA with transaction experience should model three scenarios, buyer-favorable, neutral, and seller-favorable, with after-tax proceeds on each. By the time the LOI is signed, the buyer holds leverage and pushing for better allocation terms means negotiating from weakness.
