Asset Sales: Residual Method, Allocations, and Form 8594

In an asset sale, the purchase price allocation is not a free negotiation over where to put dollars. Federal tax law requires the buyer and seller to use the residual method under IRC Section 1060: you assign the total consideration across seven asset classes in a fixed priority order, filling each class to fair market value before moving to the next, with whatever remains falling into goodwill.¹ Both sides then report identical numbers on IRS Form 8594, and those numbers control how much tax each party owes for years after closing.

The Residual Method and the Seven Classes

The mechanics work like pouring water into stacked containers. You fill Class I to its fair market value, then Class II, and so on down the list. By the time you reach Class VII, every identifiable asset has been accounted for, and any purchase price remaining above the total fair market value of Classes I through VI becomes goodwill by default.²

The classes, in allocation order:

Class I: cash and general deposit accounts (checking and savings, but not certificates of deposit).
Class II: actively traded personal property including U.S. government securities, publicly traded stock, and certificates of deposit.
Class III: debt instruments and accounts receivable, including notes receivable, typically valued at face amount minus a discount for collection risk.
Class IV: inventory and other property held primarily for sale to customers.
Class V: all other tangible and intangible assets not covered by the other classes. This catch-all usually includes machinery, equipment, furniture, vehicles, buildings, and land.
Class VI: all Section 197 intangibles except goodwill and going concern value, including workforce in place, customer lists, patents, copyrights, non-compete agreements, trade names, franchises, and government-issued licenses or permits.
Class VII: goodwill and going concern value only.

In most small and mid-market acquisitions, a significant portion of the price ends up in Class VII, because the buyer is paying a premium for the business as a going concern.

What Counts as Total Consideration

The pool you allocate is not just the cash or stock the buyer hands over. When the buyer assumes any of the seller’s liabilities as part of the deal, those assumed liabilities are added to total consideration before allocation begins.³ If the buyer pays $3 million in cash and takes on $1 million of the seller’s debt, the total consideration to allocate is $4 million.

This matters more than people expect. Sellers sometimes prefer that buyers assume equipment leases or vendor obligations instead of paying a higher cash price, but the total pool of dollars to be spread across the seven classes grows by the amount of assumed liabilities either way.

Why Buyer and Seller Pull in Opposite Directions

The allocation creates natural tension because the tax code rewards each side for pushing dollars in opposite directions. The seller generally wants more of the price allocated to assets that produce long-term capital gains, which are taxed at lower rates. The buyer wants more allocated to assets that can be written off quickly through depreciation or amortization, reducing taxable income in the early years of ownership.

Section 1060 says that if buyer and seller agree in writing on the allocation, that agreement binds both of them for tax purposes. The IRS can override the agreement only if it determines the allocation doesn’t reflect actual fair market values.¹ That binding effect is why the allocation schedule in the purchase agreement is one of the most heavily negotiated provisions in the entire deal. Once it’s signed, neither side can walk away from the numbers.

How the Allocation Taxes the Seller

For the seller, the allocation determines whether the gain on each asset is taxed as ordinary income or at the more favorable long-term capital gains rate. Assets held for more than one year in the business generally qualify for long-term capital gains treatment.⁴ Land and goodwill are the seller’s best friends here, producing pure capital gain with no recapture complications. Inventory always generates ordinary income.

Section 1245 Recapture on Equipment

The biggest tax hit for sellers usually comes from depreciation recapture on machinery, equipment, furniture, and similar personal property classified as Section 1245 property. The rule is blunt: all prior depreciation deductions on Section 1245 property must be recaptured as ordinary income when the asset is sold at a gain.⁵ If you bought equipment for $100,000, depreciated it down to $20,000, and the allocation assigns it $90,000, the $70,000 gain representing prior depreciation is taxed at ordinary income rates. Only gain above original cost qualifies for capital gains treatment.

Unrecaptured Section 1250 Gain on Real Property

Real property like commercial buildings gets different treatment. For buildings placed in service after 1986, the depreciation method is straight-line, so there’s typically no “additional depreciation” to recapture as ordinary income under Section 1250 in the traditional sense.⁶ Instead, the gain attributable to all straight-line depreciation you claimed is taxed at a maximum rate of 25%. This is called unrecaptured Section 1250 gain, and it sits between ordinary income rates and the standard long-term capital gains rate. Any gain above original cost is taxed at the regular long-term capital gains rate.⁴

The practical takeaway for sellers: dollars allocated to real property are taxed more favorably than dollars allocated to equipment, but less favorably than dollars allocated to goodwill or land. Sellers consistently push for higher allocations to Class VII goodwill and to land over equipment and buildings.

How the Allocation Deducts for the Buyer

The buyer receives a stepped-up basis in every acquired asset equal to the amount allocated to it. That basis is the starting point for future depreciation and amortization deductions, so the allocation essentially determines how fast the buyer can recover the purchase price through tax deductions.

Depreciation of Tangible Assets

Tangible personal property like machinery, office furniture, and vehicles is depreciated under the Modified Accelerated Cost Recovery System (MACRS). Most equipment falls into either the 5-year or 7-year recovery class. Nonresidential commercial buildings are depreciated over 39 years, and residential rental property over 27.5 years.⁷ The gap between a 5-year equipment deduction and a 39-year building deduction is enormous, which is why buyers push to allocate more to equipment and less to real property.

For 2026, 100% bonus depreciation is available for qualifying property, meaning a buyer can deduct the entire allocated cost of eligible equipment in the first year rather than spreading it over the standard recovery period. The Section 179 deduction also allows immediate expensing of up to $2,560,000 in qualifying asset costs, with a phase-out beginning at $4,090,000 in total qualifying purchases. These accelerated deductions make an allocation to Class V tangible assets even more valuable than the standard MACRS schedule alone would suggest.

Amortization of Intangibles

Goodwill, non-compete agreements, customer lists, patents, trade names, and most other intangibles acquired in a business purchase are classified as Section 197 intangibles. The cost allocated to these assets must be amortized on a straight-line basis over 15 years, regardless of the asset’s actual useful life.⁸ A non-compete that lasts three years still gets amortized over 15. A customer list that might lose half its value in five years still gets amortized over 15.

The 15-year rule creates a predictable tax shield, but it’s slower than what tangible equipment offers. Buyers generally prefer dollars in Class V over Class VI or VII. The exception is when the tangible asset values are already well-supported by appraisals and there’s no credible way to push more dollars there without inviting IRS scrutiny.

Supporting the Numbers Against IRS Challenge

The allocation must reflect actual fair market value. That sounds straightforward, but it’s the most subjective part of the process. Fair market value for used equipment is relatively easy to establish through comparable sales or dealer quotes. Fair market value for a customer list or a non-compete requires judgment, and the IRS knows both parties have incentives to shade those judgments.

The standard way to support your allocation is with an independent appraisal. A third-party valuation firm can assess the tangible assets, identify and value intangibles separately from goodwill, and document the methodology. The cost is small relative to the tax dollars at stake in most acquisitions.

The IRS can challenge any allocation it considers inconsistent with fair market value, even when buyer and seller have agreed in writing.¹ On audit, the agency looks for an implausibly high allocation to goodwill when the business has weak brand recognition, or an allocation to equipment that exceeds replacement cost. Both sides have an interest in getting the numbers right, because a reallocation by the IRS hurts one party while benefiting the other, and neither side controls which direction the adjustment goes.

Earnouts and Post-Closing Adjustments

Not every deal closes at a fixed price. Many asset purchases include earnouts, where part of the price depends on the business hitting revenue or profit targets after closing. Working capital adjustments are also common, with the final price shifting up or down based on the balance sheet at closing.

When total consideration changes after the year of sale, the allocation must be updated. Both buyer and seller file an amended Form 8594 with their tax return for the year the increase or decrease is recognized, showing the revised allocation across the seven classes.² The residual method applies to the adjusted total the same way it applied to the original price. If an earnout payment bumps consideration by $500,000 and all identifiable asset values remain the same, that entire increase flows to Class VII goodwill.

Earnouts also raise character questions for the seller. Whether an earnout payment is taxed as capital gain or ordinary income depends on the underlying asset class it gets allocated to. If the payment increases the goodwill allocation, it’s typically capital gain. If it increases compensation-related amounts like a non-compete, it may be ordinary income. Getting the earnout mechanics right in the purchase agreement prevents surprises at tax time.

Filing Form 8594

Both buyer and seller must attach IRS Form 8594 to their income tax return for the year the sale closes. The form is not filed separately; it goes with whatever return is due, whether that’s a Form 1040, 1065, 1120, 1120-S, or 1041.² If total consideration changes in a later year due to an earnout or working capital adjustment, both sides file an updated Form 8594 with that year’s return.

The IRS matches the two filings. If the buyer’s and seller’s returns show different allocations for the same transaction, both get flagged. This is why Section 1060 pushes the parties to agree in writing before filing: an agreed allocation binds both sides and eliminates the risk of a mismatch. Inconsistent filings create the worst kind of audit risk, where the IRS has a clear paper trail showing the parties couldn’t agree on the facts.

Penalties for Filing Errors

Form 8594 is an information return, so it’s subject to the standard information return penalties. For returns due in 2026:

Filed up to 30 days late: $60 per return.
Filed 31 days late through August 1: $130 per return.
Filed after August 1 or not filed at all: $340 per return.
Intentional disregard: $680 per return, or a percentage of the amounts that should have been reported, whichever is greater. The normal annual cap on penalties does not apply when the failure is intentional.

These per-return penalties apply to each Form 8594 that is late, missing, or contains incorrect information.⁹ The dollar amounts look modest for a single transaction, but the real cost of getting Form 8594 wrong isn’t the penalty. A missing or inconsistent form gives the IRS a reason to examine the entire transaction, including the allocation itself, the reported gain or loss, and the buyer’s depreciation and amortization deductions in every year that follows.
