Purchase Price Allocation: The Tax Form That Decides Your Gain

When you sell a business as an asset sale, every dollar of purchase price gets assigned to one of seven IRS asset classes. That assignment is not arbitrary. It decides whether your gain gets taxed at long-term capital-gains rates or as ordinary income, and it can swing your after-tax proceeds by tens of thousands of dollars. I've seen sellers overlook allocation entirely, then discover at close they're paying 50% more in tax than they expected. Don't let that be you.

The Seven Classes and the Residual Method

The IRS defines seven asset classes, allocated by the residual method. Class I is cash and cash equivalents. Class II includes securities and accounts receivable. Class III covers inventory. Class IV is property, plant, and equipment—fixtures, machinery, vehicles. Class V is intangible assets with a determinable useful life: customer lists, software licenses, covenants not to compete. Class VI covers intangible assets with indefinite useful life: trademarks, permits. Class VII is goodwill and going-concern value, the catch-all.

The residual method means you allocate dollars bottom-up. You start with Class I (what's there in cash), then Class II (what the books show), then inventory at fair market value, then tangible assets. Whatever is left after all that—your goodwill. You don't allocate to goodwill; it's whatever the sale price minus every other class equals.

Why This Matters to Your Tax Bill

The tax outcome depends on how much of your gain sits in each class. A long-term capital gain—the kind you qualify for if you've held the business over one year—gets taxed at long-term capital-gains rates of 0%, 15%, and 20%, with the 15% rate running to $533,400 single or $600,050 married filing jointly for 2025. Those are the rates most small-business sellers live in.

But here's the catch: goodwill (Class VII) and going-concern value get taxed as ordinary income to the seller. Ordinary income rates top out at 37%. A gain sitting in Class VII gets hammered compared to the same dollar in Class IV (equipment and fixtures).

This is why the allocation fight happens. Buyers want equipment valued high—depreciation recapture on what they depreciate gets capped at 25%. Sellers want the sale price pushed into goodwill—it still gets long-term capital-gains rates on the gain portion. The buyer is also buying the right to depreciate those assets for tax purposes going forward, so there's a real economic interest at play, not just gamesmanship.

How Buyers and Sellers Push and Pull

I've negotiated hundreds of allocations. The buyer's tax advisor will fight for higher Class IV, V, and VI values because those depreciate or amortize over time, creating future tax deductions. The seller's tax advisor wants more Class VII because it locks in capital-gains treatment. Neither side is wrong; they're paying different taxes on the same transaction.

The residual method actually constrains this somewhat. You can't just split the price however you want. You have to assign fair-market value to each class in order, and Class VII gets what's left. But there's room to argue about what "fair market value" means for inventory, for equipment, for a non-compete. A three-year-old drill press isn't brand new, but it's not scrap either. A customer list is only worth what a buyer will actually pay for it.

I've seen allocations where the seller and buyer fight over a $50,000 difference in equipment value. That $50,000 swing might represent a $7,500 difference in the seller's tax bill if it moves between Class IV and Class VII.

Why You File Matching Forms 8594

Both the buyer and seller file Form 8594 with the IRS—and they must match. If the buyer reports $200,000 in Class IV assets and the seller reports $150,000, the IRS notices. The buyer will depreciate those assets over time, creating deductions; if the seller's allocation doesn't align, it creates an audit flag. Most of the time, the buyer's and seller's CPAs work it out in the week before close. That's fine, but it's also dangerous.

When the allocation gets hammered out days before close, you're negotiating with the buyer's accountant under time pressure. You might accept an allocation you wouldn't have, simply because the alternative is pushing close to next week. I raise allocation in the letter of intent instead. It takes 30 seconds in the LOI to propose a reasonable split based on what I see on the books and what the buyer's reps know. Then both sides' tax advisors have weeks to comment, ask for appraisals, push back. By the time you're in purchase-agreement negotiations, this is settled.

An appraisal for equipment, inventory, or intangible assets costs $1,500 to $3,000. If you're buying a $500,000 business and the allocation might swing your tax bill by $10,000, that appraisal is worth every penny. I tell sellers to budget for it as part of the sale cost, not as an expense they negotiate away.

The Matching Form and Audit Risk

The buyer will report Class IV depreciation deductions every year going forward. If the IRS later audits you as the seller, one of the first things they'll do is check whether the Form 8594 the buyer filed matches the one you filed. Mismatches create hassle—and sometimes trigger real examinations.

I've also seen situations where the buyer's allocation was too aggressive (way too much in Class IV, too little in Class VII), and the IRS challenged it years later. If your Form 8594 doesn't match the final IRS determination, you might owe back taxes. That's why I want allocation locked in during the LOI process, with both sides' tax advisors buying in.

Getting It Right Early

Raise allocation in the LOI. Propose a reasonable split based on a walk-through of the business—what equipment is there, what inventory, what intangible value. If there are significant assets that need appraisal (machinery, customer lists, trade names), note that in the LOI too. Get the buyer and their accountant on record early. By the time you're 60 days from close, allocation should be a done deal, not a source of last-minute friction.

The residual method is mechanical once you know what each asset is worth. The fight is about valuation, not about cheating the system. But that fight is real, and it's worth winning early. I've worked with plenty of sellers in the Phoenix metro who thought allocation was a technicality their CPAs would handle. They were right that the CPAs handle it—but they were wrong to assume it was settled in their favor. Raise it yourself, get both sides aligned, and move forward with certainty about your tax outcome.
