IRS Form 8594 Explained: Purchase Price Allocation for Buyers

IRS Form 8594 (Asset Acquisition Statement Under Section 1060) reports how the purchase price in a business sale gets allocated across seven IRS-defined asset classes, from cash to goodwill. Both buyer and seller must file matching Form 8594s with their tax returns for the sale year, using the residual method to assign value class by class, and a mismatch between the two filings is one of the more reliable ways to draw IRS attention to both returns.

Most due diligence guides mention this form in a sentence or two and move on. That undersells what's actually at stake: the class-by-class allocation determines how fast a buyer can deduct what they paid, and how much of a seller's gain gets taxed at capital gains rates versus ordinary income. It's a real, quantifiable negotiation, not a compliance afterthought, and it belongs in the purchase agreement, not left to two CPAs guessing independently after closing.

Key Takeaways

• Both buyer and seller must file Form 8594, and it isn't a separate deadline; it rides along with your income tax return for the year the sale closed, including any extension.
• The seven asset classes matter because each one gets taxed differently. Class IV (inventory) and Class V (equipment) favor the buyer with faster deductions; Class VII (goodwill) favors the seller with capital gains treatment.
• A common misconception is that Class VI intangibles (non-competes, customer lists) amortize faster than Class VII goodwill. They don't. Both amortize identically over 15 years under IRC Section 197.
• Real 2026 penalties for a mismatched or incorrect Form 8594 run $60 to $680 per return depending on how late the correction comes, with an uncapped 10%-of-amount penalty for intentional disregard, not the vague "up to $50,000" figure some sources cite.
• Sellers with heavily depreciated equipment should watch Class V closely: depreciation recapture under Section 1245 taxes that portion of the gain as ordinary income, not capital gains, regardless of how the rest of the deal is structured.

What Form 8594 Actually Does

Form 8594 exists because the IRS needs both sides of an asset sale to agree, in writing, on how the price splits across categories of assets that get taxed completely differently.

Without it, a buyer and seller could each report whatever allocation benefits them most on their own separate returns, with no way for the IRS to catch the inconsistency. Form 8594 closes that gap: both parties file the same form, with the same class-by-class breakdown, and the IRS's own systems are built to flag it when the two don't match.

Who Has to File, and When

Both the buyer and the seller in an "applicable asset acquisition," generally a sale where the buyer's basis in the acquired assets is determined entirely by the purchase price, must file Form 8594. That covers most straightforward asset purchases of an SMB, and it also applies to certain stock purchases treated as asset sales for tax purposes. If you're weighing an asset deal against a stock deal, see our guide on asset purchase vs. stock purchase structures for how that choice affects this filing in the first place.

Form 8594 isn't a standalone filing with its own due date. It attaches to each party's income tax return for the year the sale closed, so it's due whenever that return is due, including any extension. If the return goes on extension (Form 4868 for individuals, Form 7004 for corporations and partnerships), the form's effective deadline moves with it automatically. If the purchase price is later adjusted up or down, both parties file a supplemental Form 8594 with the return for the year the adjustment happens, not an amended return for the original year.

Buyers and sellers each file their own copy; there's no joint submission. That's exactly why coordination matters so much, since two parties independently filling out the same allocation from memory or from different working drafts of the purchase agreement is a common, avoidable way the two filings end up mismatched.

The Seven Asset Classes, Explained

The IRS's own instructions for Form 8594 define seven classes, and the order matters because the residual method fills them in sequence.

How the Residual Method Actually Works

The residual method fills classes in order, from Class I through Class VI, at each asset's fair market value, and whatever's left of the total purchase price after that automatically becomes Class VII goodwill.

This is why goodwill is called the residual: it's not independently valued so much as it's whatever remains once every other class has been assigned real value. A business with modest tangible assets and a strong customer base or brand will naturally show a large Class VII allocation, and that's normal, not a red flag on its own.

Worked Example: Allocating a $2M Business Sale

Here's the arithmetic on a hypothetical $2,000,000 asset sale of a profitable home-services business, allocated across all seven classes:

In real negotiation, the buyer typically pushes Class V higher, toward the trucks and equipment that qualify for bonus depreciation or Section 179 expensing in year one, shrinking Class VII correspondingly. The seller pushes the other way, protecting Class VII because it's taxed at capital gains rates, and watching Class V carefully if they've already claimed significant depreciation on that equipment. Because the two sides' incentives run in opposite directions on a fixed total price, deals typically resolve by adjusting the headline price slightly rather than one side simply losing the allocation fight, then locking the final numbers into the purchase agreement so both CPAs file identical Forms 8594.

Why Buyers and Sellers Want Different Allocations

The short answer: every class is taxed differently on each side of the table, so the allocation is a real transfer of value even when the total price doesn't change.

Buyers want value pushed into Class IV and Class V because inventory becomes an immediate deduction as it's sold, and equipment depreciates over 5 to 7 years, often with bonus depreciation or Section 179 expensing available in year one. Buyers want to minimize Class VI and VII, since both amortize slowly over 15 years regardless of which of the two you're arguing about.

Sellers want the opposite. Goodwill in Class VII, for a business held more than a year, is generally eligible for long-term capital gains treatment at 0%, 15%, or 20% federally (plus a possible 3.8% Net Investment Income Tax for high earners) rather than ordinary income rates that can reach 37%. That gap is exactly why sellers negotiate hard to keep the goodwill number high.

Depreciation Recapture: The Trap in Class V

Sellers with heavily depreciated equipment should scrutinize Class V more than they might expect, because it isn't automatically capital gains just because the asset is tangible property.

Under IRC Section 1245, any gain on depreciable tangible property, up to the amount of depreciation the seller already claimed, gets recaptured and taxed as ordinary income. Only gain above the original cost basis gets capital gains treatment. A seller who's depreciated $300,000 of equipment down close to zero will owe ordinary income tax on the recaptured portion of any Class V allocation up to that $300,000, no matter how favorable the rest of the deal looks.

2026 Capital Gains Thresholds

For sellers weighing how much of the price to fight for in Class VII, the actual 2026 federal long-term capital gains brackets, per IRS Revenue Procedure 2025-32, are:

These are taxable income thresholds, not deal size, so a seller's total income for the year, including the gain itself, determines which bracket applies.

Penalties: What a Mismatch or Late Filing Actually Costs

The real 2026 penalty structure under IRC Sections 6721 and 6722 (per the same Revenue Procedure 2025-32) is tiered, not a flat "up to $50,000" figure some guides cite with no real source: $60 per return if corrected within 30 days, $130 per return if corrected by August 1, $340 per return for the general penalty, and $680 per return, or 10% of the amount required to be reported, whichever is greater and uncapped, for intentional disregard. Annual aggregate caps run $1,397,000 for smaller filers and $4,191,500 for larger ones.

The uncapped 10%-of-amount provision is the one that actually stings on a real acquisition. On a $2M allocation dispute treated as intentional disregard, that's a real, six-figure exposure, which is a stronger reason to get the allocation agreed and documented before closing than any flat penalty figure would suggest.

Common Form 8594 Mistakes That Trigger IRS Scrutiny

• Filing without coordinating with the other party first. Independent estimates from two different CPAs rarely land on identical numbers.
• Leaving the allocation out of the purchase agreement. If it's not in writing in the deal documents, it's not locked, and post-closing disagreement becomes likely.
• Treating Class VI as a faster deduction than Class VII. Both amortize over the same 15 years; fighting over this split specifically wastes negotiating leverage that would matter more spent on Class IV/V.
• Ignoring Section 1245 recapture on Class V. A seller who doesn't account for recapture can be surprised by an ordinary-income tax bill they didn't budget for.
• Forgetting the supplemental filing after a post-closing price adjustment. An earnout or working capital true-up that changes the final price requires a supplemental Form 8594, not silence.

How to Get Buyer and Seller Filings Aligned Before Closing

Negotiate the class-by-class allocation as part of the purchase agreement itself, not as a handshake understanding to be sorted out later. For the broader set of terms worth locking down at the same time, see our guide to common purchase agreement mistakes.

Once the numbers are agreed, confirm directly with the other side's CPA, not just your own, that both Forms 8594 will use the identical class-by-class breakdown before either return is filed. This is one of the cheapest, most concrete due diligence items available: a single phone call between accountants that prevents a real, quantifiable IRS mismatch. For the rest of what belongs on your closing checklist, see our full due diligence checklist.

Form 8594 isn't a form you fill out after the deal is done. The allocation it reports is a real negotiation with real dollars attached, and the buyer and seller who agree on it explicitly, in the purchase agreement, before either CPA touches a tax return, are the ones who avoid a mismatch neither side saw coming.
