Comparing Bitcoin under IFRS vs US GAAP comes down to one point. US GAAP now requires in-scope Bitcoin to be measured at fair value through net income, while IFRS has no equivalent rule and usually treats Bitcoin as an intangible asset under IAS 38. The same holding can therefore produce a different profit, a different equity split and a different deferred tax balance depending on the framework.
We explain each framework on its own in ASU 2023-08: fair value accounting for Bitcoin explained and how Bitcoin is accounted for under IFRS. This article puts them side by side, shows how the numbers diverge, and sets out how groups reporting under both can manage the gap.
Where the two frameworks start
The frameworks reached their positions by different routes.
US GAAP has a dedicated standard. The FASB standard on digital assets (ASU 2023-08), codified in ASC 350-60, applies to fiscal years beginning after 15 December 2024, with early adoption permitted. In-scope assets, including Bitcoin, are measured at fair value at each reporting date, with changes recognised in net income.
IFRS has no dedicated standard. The position rests on the IFRS Interpretations Committee agenda decision of June 2019. It concluded that holdings such as Bitcoin are neither cash nor financial assets. They are generally intangible assets under IAS 38, or inventory under IAS 2 if held for sale in the ordinary course of business.
One framework has a rule written for the asset. The other applies a standard designed for patents, licences and brands.
Bitcoin under IFRS vs US GAAP at a glance
| Topic | US GAAP (ASC 350-60) | IFRS (IAS 38, typical treasury holder) |
|---|---|---|
| Measurement after purchase | Fair value at every reporting date | Cost less impairment, or revaluation to fair value if an active market exists |
| Price rises | Gain in net income | Cost model: not recognised above cost. Revaluation model: other comprehensive income (OCI) |
| Price falls | Loss in net income | Profit or loss (revaluation model: first against any surplus in OCI) |
| Recovery after a fall | Gain in net income | Cost model: impairment reversal, capped at original cost |
| Gain on sale | Net income | Cost model: profit or loss. Revaluation model: surplus transferred to retained earnings, not recycled |
| Fair value guidance | ASC 820 | IFRS 13 |
| Bitcoin-specific disclosures | Prescribed | None; general IAS 1, IAS 38 and IFRS 13 requirements apply |
IAS 2 inventory treatment, including fair value less costs to sell for commodity broker-traders, applies only to entities that buy and sell Bitcoin as part of their business. A corporate treasury holding Bitcoin as a reserve will not normally qualify.
How the same holding reports differently
Consider an illustrative example. A company buys 100 BTC at 40,000 each, a cost of 4,000,000. At the end of year one the price is 50,000. At the end of year two it is 35,000. Ignore transaction costs and tax.
- US GAAP. Year one: carrying amount 5,000,000, gain of 1,000,000 in net income. Year two: carrying amount 3,500,000, loss of 1,500,000 in net income.
- IFRS cost model. Year one: carrying amount stays at 4,000,000, nothing recognised. Year two: impairment of 500,000 in profit or loss, carrying amount 3,500,000.
- IFRS revaluation model. Year one: carrying amount 5,000,000, with 1,000,000 in OCI and a revaluation surplus. Year two: the 1,500,000 fall first reverses the 1,000,000 surplus through OCI, and the remaining 500,000 goes to profit or loss.
By the end of year two, all three end with the same balance sheet value and the same cumulative 500,000 loss in profit. What differs is when profit moves, and whether some of the movement passes through OCI instead.
The asymmetry shows most in a rising market. Had the price ended year two at 60,000, the US GAAP reporter would show a further gain in net income. The IFRS cost-model reporter would still show the asset at 4,000,000 and no gain at all.
Differences below the headline
Several smaller points cause friction in practice.
Transaction costs
Both frameworks exclude transaction costs from fair value. Under IAS 38, directly attributable acquisition costs form part of cost. Under US GAAP, ASU 2023-08 did not change initial measurement, so any commission capitalised on purchase is absorbed into the first remeasurement. See accounting for Bitcoin trading and network costs.
Impairment testing
An IFRS cost-model reporter tests for impairment under IAS 36, at least annually for an indefinite-lived asset and whenever there is an indication of impairment. A US GAAP reporter applying ASU 2023-08 does not run impairment tests on in-scope holdings, because fair value is already recognised.
Deferred tax
Under both ASC 740 and IAS 12, deferred tax follows the gap between carrying amount and tax base. Different carrying amounts mean different deferred tax balances. Under the IFRS revaluation model, deferred tax on a revaluation gain is recognised in OCI, alongside the gain itself. See deferred tax on corporate Bitcoin holdings.
Scope at the edges
ASU 2023-08 has specific scope criteria. Assets that give the holder enforceable rights to underlying goods, services or other assets, such as many stablecoins and some wrapped tokens, are generally outside it. IFRS analysis starts from the general definitions of financial assets and intangible assets. The same instrument can land in different places under each framework.
Disclosure
US GAAP prescribes holdings, cost basis, restrictions and an annual roll-forward. IFRS relies on general requirements, though many IFRS reporters voluntarily provide similar detail so that investors can compare. See Bitcoin disclosure requirements in financial statements.
Bridging the gap in a dual-reporting group
A common case is a subsidiary reporting locally under IFRS while the parent files under US GAAP, or the reverse. Practical steps:
- One lot register. Keep a single lot-level record of acquisition date, units, price and costs. Both frameworks draw from it.
- One pricing policy. Use the same principal market analysis, pricing source and cut-off time for ASC 820 and IFRS 13 measurements.
- Parallel carrying amounts. Track the IFRS carrying amount (cost less impairment, or revalued amount and surplus) alongside fair value, so the conversion adjustment can be calculated every period.
- A documented bridge. Reconcile profit and equity between frameworks in a schedule the auditor can follow.
- Framework-specific deferred tax. Calculate deferred tax under each framework from its own carrying amount.
CFO tip: if your group reports under both frameworks, choose the IFRS model with the conversion in mind. The revaluation model keeps the IFRS balance sheet at fair value, so the bridge only has to explain where gains are reported, not the value of the asset.
Choosing and explaining your position
An IFRS reporter holding Bitcoin as a treasury reserve cannot elect fair value through profit or loss. Its real choice is between the IAS 38 cost model and the revaluation model, where an active market exists. The choice applies to the whole class of asset and belongs in the accounting policy.
Whatever the framework, the board and investors need a plain explanation of what the reported numbers show. Peers under the other framework will report the same price move differently, and comparisons should allow for that. Companies should take their own accounting, tax and legal advice.
