The like-kind exchange GAAP treatment is governed by ASC 845, which requires you to measure the transaction at fair value and recognize any gain or loss immediately when the exchange has commercial substance. When commercial substance is absent, you record the asset received at the carrying amount of the asset given up, recognize losses right away, and defer gains unless cash (boot) changes hands. These accounting rules are separate from the tax deferral available under Internal Revenue Code Section 1031, which applies only to exchanges of real property held for business or investment purposes.1Office of the Law Revision Counsel. 26 U.S. Code 1031 – Exchange of Real Property Held for Productive Use or Investment A transaction can qualify for Section 1031 deferral and still produce a book gain on the income statement, or the reverse.
The Commercial Substance Test
Commercial substance is the single question that drives everything else: how you measure the new asset, whether a gain hits the income statement, and how any boot flows through the entries.
An exchange has commercial substance when your future cash flows are expected to change significantly as a result. Under ASC 845-10-30-4, a significant change exists if either of two conditions is met:
- The risk, timing, or amount of cash flows from the asset received differs significantly from those of the asset given up. A change in any one of the three elements is enough.
- The entity-specific value of the asset received differs from the entity-specific value of the asset surrendered, and that difference is significant relative to the fair values exchanged.
Entity-specific value matters because two assets can carry identical market prices yet produce very different cash flows for a particular company.2Deloitte Accounting Research Tool. Roadmap: Impairments and Disposals of Long-Lived Assets and Discontinued Operations – Section: 4.3 Nonmonetary Exchange An exchange lacks commercial substance when your economic position stays essentially the same afterward. Swapping an older forklift for a newer model of the same forklift, used the same way in the same facility, is the classic example.
Measuring the Asset Received
Once commercial substance is settled, measurement follows directly. Either you record the new asset at fair value, or you record it at the carrying amount of the old one.
Fair Value Measurement
If the exchange has commercial substance and fair value is reliably determinable, record the asset received at fair value. The standard directs you to use the fair value of whichever side is more clearly evident: the asset given up or the asset received. In practice, this often means using the fair value of the asset surrendered when market data is readily available for it. The measurement must comply with ASC 820, which requires observable market data or defensible valuation techniques within a three-level hierarchy.3Deloitte. Fair Value Measurements and Disclosures
Carrying Amount Measurement
ASC 845-10-30-3 identifies three situations where you use carrying amount instead:
- The exchange lacks commercial substance.
- Fair value is not reliably determinable for either side of the exchange.
- The transaction is an exchange of products held for sale in the ordinary course of business for similar products to be sold in the same line of business. Here the new inventory takes the carrying amount of the inventory surrendered.
Recording at carrying amount means the new asset simply inherits the book value of the old one. No gain hits the income statement, and the new asset’s depreciable basis equals the old asset’s carrying amount. That preserved basis carries forward for depreciation and future impairment testing under ASC 360.2Deloitte Accounting Research Tool.

Recognizing Gains and Losses
When the Exchange Has Commercial Substance
Treat it like a sale followed by a purchase. Gains and losses are both recognized immediately. The gain or loss equals the fair value of what you received minus the carrying amount of what you gave up.
Suppose you exchange equipment with a carrying amount of $50,000 for new equipment with a fair value of $65,000. You record the new equipment at $65,000 and recognize a $15,000 gain. If the new equipment were worth only $40,000, you would record a $10,000 loss. The full amount hits the income statement in the period of the exchange either way.
When the Exchange Lacks Commercial Substance
The treatment turns asymmetric. Losses are still recognized immediately. GAAP’s conservatism principle does not let you carry an asset at more than its recoverable amount, so any decline in value must appear in the financial statements regardless of commercial substance.
Gains are deferred. Record the new asset at the carrying amount of the old one, which pushes the unrealized gain into the new asset’s lower basis. That deferred gain works its way into income over time through lower depreciation expense, or when you eventually sell the new asset in a transaction that culminates the earnings process.2Deloitte Accounting Research Tool.

How Boot Changes the Accounting
Boot is cash or other monetary consideration included in an exchange to equalize values. Its presence can change the entire model, not just the numbers.
The 25% Threshold
This is where preparers often trip. Under ASC 845-10-25-6, when boot equals or exceeds 25% of the total fair value of the exchange, the whole transaction is treated as a monetary exchange rather than a nonmonetary one. That means full fair value measurement and immediate recognition of all gains and losses, even if the exchange would otherwise lack commercial substance.4Deloitte Accounting Research Tool. Roadmap: Revenue Recognition – Section: 3.2 Scope
The denominator is the fair value of the exchange. If the total fair value of the deal is $200,000 and cash of $50,000 changes hands, boot is exactly 25% and the entire exchange is monetary. Drop the cash to $49,000 and you are below the threshold, which triggers the partial gain recognition rules instead.
Boot Received Below the Threshold
When you receive boot in an exchange that lacks commercial substance and the boot is under 25% of fair value, you recognize a portion of the gain proportional to the cash received. ASC 845-10-30-6 defines the recognized gain as the monetary consideration received minus a proportionate share of the carrying amount of the asset surrendered. The proportionate share is based on the ratio of cash received to total consideration received.4Deloitte Accounting Research Tool. Roadmap: Revenue Recognition – Section: 3.2 Scope
A shortcut reaches the same number: multiply the total gain by the ratio of cash received to total consideration. Say you give up an asset with a $70,000 carrying amount and receive $10,000 in cash plus an asset worth $90,000. Total consideration is $100,000. The total gain is $30,000. The boot ratio is 10%. You recognize $3,000 of the gain immediately, and the remaining $27,000 is deferred by reducing the recorded basis of the nonmonetary asset received.
Boot Paid
Paying boot in an exchange that lacks commercial substance does not trigger any gain recognition. The cash you pay simply increases the basis of the new asset. If you exchange equipment with a $40,000 carrying amount and pay $5,000 in cash, the new asset goes on your books at $45,000. That figure becomes the basis for depreciation going forward.
Test for Impairment Before Recording the Exchange
An asset you plan to dispose of through a nonmonetary exchange measured at carrying amount stays classified as held and used until the exchange actually occurs. While it remains in that classification, you test it for impairment under the normal ASC 360 rules, and the cash flow estimates in that test should assume the exchange will not happen.5PwC. Property, Plant and Equipment – Section: 6.3 Disposals Other Than by Sale
At the point of disposal, recognize any additional impairment if the carrying amount exceeds fair value. Sequence matters: an impairment recognized just before the exchange reduces the carrying amount, which changes any gain or loss flowing through the exchange calculation. Skipping this step is a common audit finding.
What Falls Outside ASC 845
ASC 845 covers reciprocal exchanges of nonmonetary assets between entities. Several transactions that look similar are governed by other standards:
- Nonmonetary consideration in a contract with a customer is measured under ASC 606, not ASC 845. Noncash consideration is measured at fair value at contract inception and may involve variable consideration estimates.
- Nonmonetary assets acquired in a business combination are measured under ASC 805 at fair value, regardless of commercial substance.
- Contributions or distributions to owners are nonreciprocal transfers, addressed separately under ASC 845-10-30 and measured at fair value of the asset transferred.
The inventory rule inside ASC 845 deserves its own note. When two companies in the same line of business swap inventory to facilitate sales to their respective customers, ASC 845 still applies, but it forces carrying amount measurement. The logic is that these swaps are logistical convenience, not genuine earnings events.2Deloitte Accounting Research Tool.

Working the Analysis in Order
When a nonmonetary exchange lands on your desk, work through the questions in this sequence. Confirm the transaction is inside ASC 845’s scope and not governed by ASC 606, ASC 805, or other guidance. Test the asset given up for impairment under ASC 360, since the resulting carrying amount feeds every calculation that follows. Determine whether the exchange has commercial substance using the cash flow configuration and entity-specific value tests. If boot is present, check whether it equals or exceeds 25% of total fair value.
If commercial substance exists or boot crosses 25%, measure at fair value and recognize all gains and losses immediately. If commercial substance is absent and boot is below 25%, measure the nonmonetary asset at carrying amount, recognize losses immediately, defer gains, and apply the partial gain formula to any boot received.
