DAC8 Reporting, CARF, IFRS, and US GAAP: Crypto Financial Reporting Standards Explained
Crypto financial reporting has moved from a niche concern to a board-level priority. Accounting firms, CFOs, and finance teams now face overlapping obligations: DAC8 reporting requirements in the EU, CARF crypto reporting under the OECD framework, fair value measurement under FASB's updated guidance, and the continuing absence of a dedicated IFRS standard for crypto assets. South Korea has added its own layer, requiring virtual asset service providers and their users to meet detailed disclosure rules that increasingly align with international expectations. Understanding how these frameworks connect is essential for any firm advising clients who hold, trade, or issue digital assets across borders.
The Global Push Toward Standardised Crypto Reporting
Before 2023, crypto financial reporting was characterised by patchwork national rules and significant practitioner discretion. That has changed. The OECD's Crypto-Asset Reporting Framework, widely known as CARF, established a common international standard for the automatic exchange of information on crypto transactions between tax authorities. CARF crypto reporting covers a broad scope of assets and intermediaries, and it has served as a template that many jurisdictions are now enacting into domestic law.
The EU followed with DAC8, an amendment to the Directive on Administrative Cooperation that incorporates the CARF principles directly into EU law. DAC8 reporting applies to crypto-asset service providers operating in the EU and requires them to collect, verify, and report user transaction data to national tax authorities, who then share it across member states. The practical implication for accounting firms is significant: clients who previously had no formal reporting infrastructure for crypto holdings now face structured obligations with specific deadlines and penalties for non-compliance.
South Korea has pursued a parallel but distinct path. The country's Financial Services Commission has progressively tightened the regulatory perimeter around virtual asset service providers, and reporting requirements now extend to annual disclosures of virtual asset holdings and transaction activity. Korean firms with international investors or cross-border operations increasingly need to reconcile their domestic obligations with CARF and DAC8 frameworks, creating a complex compliance matrix that advisers must navigate carefully.
DAC8 Reporting: What Accounting Firms Must Understand
DAC8 is not simply a data-sharing mechanism. It reshapes the compliance obligations of any firm that qualifies as a reporting crypto-asset service provider under the directive. The definition is broad and includes entities that execute transactions in crypto assets on behalf of clients, as well as those that facilitate transfers. Firms advising clients in this space need to understand both the scope of who must report and the categories of information that must be captured.
The following table summarises the key reporting dimensions under DAC8 as they compare to CARF at the OECD level.
| Dimension | CARF (OECD) | DAC8 (EU) |
|---|---|---|
| Legal basis | Model rules for domestic enactment | EU directive, binding on member states |
| Reporting entities | Reporting crypto-asset service providers | CASPs as defined under MiCA |
| Data reported | Transaction volumes, consideration, asset type | Same scope plus identification data |
| Exchange mechanism | Bilateral or multilateral competent authority agreements | Automatic exchange via EU common platform |
| Penalties | Set by each implementing jurisdiction | Minimum penalty floors required by member states |
For firms with EU-registered clients or EU-passported service providers, DAC8 reporting creates immediate practical obligations around data collection processes, client due diligence records, and annual submission workflows. Firms that handle crypto compliance reporting should review whether any of their clients qualify as reporting entities and build the necessary infrastructure well before submission deadlines arrive.
CARF Crypto Reporting and South Korea's Alignment
South Korea is not an EU member state and is therefore outside the scope of DAC8 directly. However, as an OECD member, South Korea has engaged with the CARF framework and has been moving its domestic virtual asset reporting regime closer to CARF standards. Korean virtual asset service providers are already subject to real-name account verification requirements and transaction reporting obligations to the Korea Financial Intelligence Unit. The evolution toward CARF-aligned automatic exchange represents the next step.
For accounting firms advising multinational clients with Korean operations, the practical challenge is dual-track compliance: meeting Korean domestic obligations while simultaneously ensuring that the data produced is compatible with the CARF reporting structures that other jurisdictions will request. This is not a theoretical risk. Korean exchanges with international user bases or foreign-owned entities operating in Korea may already fall within the scope of multiple reporting regimes simultaneously.
The table below sets out a simplified comparison of how South Korea's current virtual asset reporting rules sit alongside CARF requirements.
| Reporting Area | South Korea (Current Rules) | CARF Standard |
|---|---|---|
| AML and identity verification | Mandatory real-name accounts and VASP registration | Reportable user identification required |
| Transaction reporting | Suspicious transaction and threshold reports to KFIU | Aggregate transaction reporting to tax authority |
| Automatic information exchange | Under development via OECD engagement | Core mechanism of the framework |
| Asset scope | Virtual assets as defined under VASP Act | Crypto assets including stablecoins and certain tokens |
IFRS Crypto Assets: The Accounting Standards Gap
While regulatory reporting frameworks like CARF and DAC8 have advanced quickly, the accounting standards picture for crypto assets under IFRS remains less settled. The International Accounting Standards Board has not issued a dedicated IFRS standard for crypto assets. Instead, practitioners have relied on IAS 38 (intangible assets) or, where applicable, IAS 2 (inventories) to account for holdings. This creates measurement inconsistency, particularly around how unrealised gains and losses are recognised.
The IASB published an agenda decision through the IFRS Interpretations Committee that confirmed most cryptocurrencies should be treated as intangible assets under IAS 38, unless they are held for sale in the ordinary course of business, in which case IAS 2 may apply. Neither treatment reflects the economic reality of assets that are actively traded at market prices and whose values fluctuate continuously. Crypto ifrs accounting therefore remains an area where professional judgement is required at every reporting date, and where firms advising IFRS-reporting clients need documented accounting policies that can withstand audit scrutiny.
South Korean listed companies follow K-IFRS, which is substantially converged with IFRS. The gap in international standards therefore affects Korean public companies directly, and firms advising them face the same interpretive challenges as those advising European or UK-listed entities.
US GAAP: FASB's Fair Value Approach Under ASC 350-60
The United States has moved further than IFRS in formalising crypto accounting rules. The Financial Accounting Standards Board issued ASC 350-60, which requires entities to measure crypto assets at fair value at each reporting date, with changes recognised in net income. This fair value model, now effective for fiscal years beginning after a specified date, represents a significant departure from the previous cost-less-impairment model that many US entities had applied.
The practical effect of FASB crypto fair value accounting is that US GAAP-reporting entities holding crypto assets will see their income statements reflect unrealised gains and losses in each period. This increases earnings volatility but also arguably improves transparency. For accounting firms advising US-listed clients or clients that report under US GAAP by choice, implementing asc 350-60 crypto requires updated chart-of-accounts structures, revised close processes, and clear disclosures in the notes to financial statements.
Crypto US GAAP accounting under ASC 350-60 also introduces specific disclosure requirements, including the name, cost basis, fair value, and number of units held for each significant crypto asset. Firms need to ensure that client systems can produce this data reliably, which often requires integration between exchange or wallet data and the general ledger.
Practical Implications for Accounting Firms
The convergence of DAC8 reporting, CARF crypto reporting, IFRS interpretations, and US GAAP's ASC 350-60 creates a multi-standard environment that firms must navigate on behalf of clients. Several practical actions follow from this landscape.
First, client segmentation matters. Firms should identify which clients are subject to which reporting frameworks based on jurisdiction of incorporation, listing status, and whether they operate as virtual asset service providers. A Korean exchange with EU users may simultaneously face Korean VASP Act obligations, DAC8 reporting through its EU-based subsidiary, and CARF exchange obligations as Korea implements the framework domestically.
Second, accounting policy documentation is non-negotiable. Whether a client reports under IFRS crypto assets rules or crypto US GAAP accounting standards, the chosen policy must be documented, applied consistently, and disclosed adequately. Auditors will increasingly challenge undocumented or inconsistently applied policies as crypto holdings grow in materiality.
Third, data infrastructure is the bottleneck. The quality of DAC8 and CARF submissions depends on complete and accurate transaction records. Firms that rely on manual extracts from exchange accounts or spreadsheet-based reconciliations will struggle to meet the data quality standards these frameworks require. Automation through a dedicated crypto compliance reporting platform is no longer optional for firms with more than a handful of crypto-active clients.
Illustrative Scenario
To illustrate how this applies in practice, consider the following scenario: Min-jun is a senior manager at a mid-size Korean accounting firm that recently began advising a virtual asset exchange with operations in both Seoul and Amsterdam. The Amsterdam entity is a registered crypto-asset service provider under MiCA, which means DAC8 reporting obligations apply from the first reporting period. The Seoul parent must simultaneously comply with Korean VASP Act requirements, including real-name account verification and threshold-based transaction reporting to the Korea Financial Intelligence Unit.
Min-jun's firm needed to produce consolidated financial statements for the group under K-IFRS, which required a documented accounting policy for the exchange's proprietary crypto holdings. Because no dedicated IFRS standard exists, the firm adopted IAS 38 treatment for the parent's holdings and ensured the policy was disclosed clearly in the notes. For the Amsterdam subsidiary, the firm implemented a crypto compliance reporting workflow using CryptaCount to capture the transaction data required for DAC8 submissions, map it to the correct reporting categories, and produce the XML output required by the Dutch tax authority. The dual-track approach meant Min-jun's team could satisfy both jurisdictions without duplicating effort, using a single data source reconciled against exchange APIs.
Frequently Asked Questions
What is DAC8 reporting and who does it apply to?
DAC8 is an EU directive that requires crypto-asset service providers operating in the EU to collect and report user transaction data to national tax authorities, who then share it automatically with other member states. It applies to entities that qualify as CASPs under MiCA, including exchanges, brokers, and transfer services. Firms advising EU-registered crypto businesses need to assess whether their clients fall within scope and build compliant data collection processes.
How does CARF crypto reporting differ from DAC8?
CARF is an OECD model framework that sets the international standard for automatic exchange of crypto transaction information between tax authorities. DAC8 incorporates CARF principles into EU law, making them legally binding for EU member states. Outside the EU, countries implement CARF through domestic legislation or bilateral agreements, which means the scope and timeline vary by jurisdiction.
What accounting standard applies to crypto assets under IFRS?
There is no dedicated IFRS standard for crypto assets. The IFRS Interpretations Committee confirmed that most cryptocurrencies should be treated as intangible assets under IAS 38, unless held for sale in the ordinary course of business, where IAS 2 may apply. Neither standard was designed for digital assets, so firms must apply professional judgement and document their chosen policy carefully for audit purposes.
What does ASC 350-60 require for crypto US GAAP accounting?
ASC 350-60, issued by FASB, requires entities to measure crypto assets at fair value at each reporting date, with changes recognised directly in net income. This replaced the previous cost-less-impairment model and introduces specific disclosure requirements, including the cost basis, fair value, and unit count for each significant crypto asset. Firms implementing this standard need reliable data pipelines from wallets and exchanges into the general ledger.
How does FASB crypto fair value measurement affect financial statements?
Under the fair value model, unrealised gains and losses on crypto holdings flow through the income statement each reporting period, which can increase earnings volatility. This improves transparency but requires entities to obtain reliable market prices at each period end and maintain audit trails supporting those valuations. Finance teams and their auditors need to agree on acceptable pricing sources in advance.
Does South Korea follow IFRS or its own accounting standards for crypto?
South Korean listed companies follow K-IFRS, which is substantially converged with international IFRS. This means Korean public companies face the same gap as European and UK entities: no dedicated standard exists, and practitioners must apply IAS 38 or IAS 2 with documented judgement. Korean private companies may use different local standards, so the applicable framework depends on the entity type and listing status.
Are South Korean companies subject to CARF crypto reporting?
South Korea is an OECD member and has been engaging with the CARF framework. While full automatic exchange under CARF is still being implemented domestically, Korean virtual asset service providers already face AML-related reporting obligations. Firms advising clients with Korean operations should monitor the timeline for CARF implementation and prepare data infrastructure accordingly.
What steps should accounting firms take to prepare for DAC8 and CARF compliance?
Firms should start by identifying which clients operate as crypto-asset service providers or hold material crypto assets across multiple jurisdictions. Next, they should review whether existing accounting policies are documented and defensible under IFRS crypto assets rules or ASC 350-60. Finally, firms should assess whether current data collection processes can produce the transaction-level detail required for DAC8 and CARF submissions, and implement automated reconciliation tools where manual processes fall short.
