EU MiCA Review Consultation: What Accounting Firms and CFOs Must Act On Now
The European Commission launched a formal public consultation on 19 May 2026 to assess whether the Markets in Crypto-Assets Regulation remains fit for purpose. The deadline for responses is 31 August 2026. For accounting firms, auditors, and CFOs with any EU digital asset exposure, this is not a theoretical policy exercise: every major pillar of MiCA, covering stablecoin issuers, crypto-asset service providers, DeFi, NFTs, staking, and the legal treatment of tokens, is on the table for potential amendment or supplementation. The scope of questions signals that legislative change is a real possibility, not a remote one.
The Legal Basis and What It Requires
The consultation is rooted in Articles 140 and 142 of MiCA, which place a mandatory obligation on the Commission to evaluate the regulation's application and to submit a formal report to the European Parliament and Council. That report may be accompanied by a legislative proposal. This is not discretionary outreach: it is a structured review cycle built into the regulation itself.
Why the Timing Matters for Compliance Teams
MiCA's full application only took effect at the end of 2024, yet markets have already moved well beyond the assumptions built into the original text. Traditional financial institutions are entering the crypto and tokenised asset space in volume. DeFi protocols have scaled. New asset categories have emerged that do not map cleanly onto existing definitions. The Commission's own framing of the consultation acknowledges that MiCA should not be treated as a completed project, particularly given competitive pressure from other jurisdictions and rapidly shifting technological conditions. Compliance teams that treat the current text as settled law are, at minimum, underestimating the planning horizon.
What the Consultation Actually Covers
The questions span the entire architecture of MiCA. Understanding the scope is essential for firms deciding where to focus their own consultation submissions and internal impact assessments.
Conditions for Offering Crypto-Assets and Admission to Trading
The consultation revisits the foundational conditions under which crypto-assets can be offered to the public or admitted to trading. This area directly affects how issuers prepare white papers, how disclosure obligations are structured, and how auditors assess the completeness of prospectus-equivalent documentation. Any tightening or relaxation of these conditions will flow through to audit scope and accounting for proceeds from token offerings.
Asset-Referenced Tokens and E-Money Tokens
Requirements for ART and EMT issuers, including reserve composition, redemption rights, and capital buffers, are explicitly under review. For firms advising stablecoin issuers or holding ARTs and EMTs on behalf of clients, this section carries the most immediate accounting relevance. Reserve assets held against an ART are currently accounted for under IAS 32 and IFRS 9 depending on their nature; any change to reserve eligibility criteria or redemption mechanics could require a reassessment of how those instruments are classified and measured on the issuer's balance sheet. The same applies to USDC accounting and similar USD-denominated EMTs issued under MiCA authorisation: if reserve requirements tighten or redemption terms are revised, the liability classification and disclosure obligations for issuers will need to be revisited.
Crypto-Asset Service Providers
The suitability of the current CASP framework is another open question. The consultation examines whether existing organisational, conduct, and prudential requirements remain appropriate. For accounting firms running due diligence engagements or providing agreed-upon procedures over CASP controls, any expansion of CASP obligations, whether covering new service categories or raising capital thresholds, will need to be reflected in engagement scope. You can see how enforcement gaps have already emerged in the current framework by reviewing Belgium FSMA enforcement after the MiCA deadline.
DeFi: Due Diligence and Smart Contract Certification
The DeFi questions are among the most consequential in the consultation. The Commission asks whether CASPs that connect clients to DeFi protocols should be required to conduct due diligence over those protocols. It also asks whether certification schemes for smart contracts are warranted. If either obligation is introduced, it will create a new category of attestation work: firms may be asked to opine on the adequacy of a CASP's DeFi protocol due diligence, or to provide assurance over smart contract audit results as part of a certification regime. DeFi accounting currently sits in a grey zone under IFRS because the absence of a counterparty in many protocols makes it difficult to apply standard derecognition and recognition tests. Regulatory clarity, if it arrives, will reduce that ambiguity but will also introduce new disclosure requirements that need to be mapped to chart-of-accounts structures.
Staking, Lending, and Borrowing
The consultation asks whether staking, lending, and borrowing require dedicated regulatory treatment. Under current IFRS practice, staking rewards are typically recognised as income when the right to receive them becomes unconditional, but the classification of the staked asset itself, whether it is derecognised or remains on balance sheet, depends on the specific protocol mechanics. A dedicated regulatory framework, if introduced, could force a more standardised accounting treatment by clarifying who holds legal title during a staking or lending arrangement and what redemption rights exist. CFOs running treasury operations that include staked ETH, liquid staking tokens, or on-chain lending positions should be tracking this area closely.
NFT Service Providers and Prediction Markets
The consultation asks whether NFT service providers should be brought under a regulatory framework and whether prediction markets and perpetual futures belong under MiFID II or MiCA. Both questions have accounting implications. If NFT service providers are regulated, revenue recognition, client asset safeguarding, and reporting obligations will need to follow. The MiFID versus MiCA classification question for perpetual futures determines which prudential and disclosure regime applies to firms offering or holding those instruments, including how mark-to-market gains and losses are reported.
Legal Treatment of Tokens: Ownership, Custody, and Insolvency
One of the most technically complex sections addresses the legal treatment of tokens, covering ownership rights, custody arrangements, collateral enforceability, and insolvency proceedings. The Commission is asking whether EU-level harmonisation is needed to support tokenisation markets. This directly affects how custodians account for client digital assets: whether they appear on or off the custodian's balance sheet, how they are treated in a counterparty insolvency, and what disclosures are required under IFRS 7. The absence of harmonised rules across EU member states currently creates genuine uncertainty in group financial statements where custody arrangements span multiple jurisdictions.
Accounting and Audit Implications by Area
IFRS Considerations Under a Revised MiCA
IFRS does not yet have a dedicated standard for crypto assets. The IASB's agenda decision confirmed that IAS 38 applies to most crypto assets held as intangibles, but the treatment of ARTs, EMTs, and tokenised financial instruments is more nuanced. Any revision to MiCA's definitions or reserve requirements will create pressure on preparers to reassess asset classification, impairment testing, and fair value disclosure under IFRS 13. Firms advising IFRS preparers should monitor the consultation outcome and map proposed changes to existing accounting policy decisions. For those working with US-listed entities or dual reporters, the interaction with ASC 350-60, the FASB's fair value standard for crypto assets, will also need to be assessed if MiCA changes alter the legal or contractual characteristics of tokens held.
Audit Scope and Assurance
A broader MiCA scope means broader audit exposure. If DeFi protocols, staking arrangements, or NFT service providers come within the regulatory perimeter, firms will need to assess whether existing engagement letters and risk frameworks adequately cover those areas. The smart contract certification question, in particular, could create a new category of assurance engagement that sits at the intersection of technology audit and financial audit. Preparing methodology now, before any final rules are published, is the sensible approach.

The Simplification Agenda
The consultation explicitly invites feedback on whether existing administrative and regulatory burdens under MiCA can be reduced. This is part of the Commission's broader competitiveness agenda. For firms, this opens a genuine opportunity: if your clients face disproportionate compliance costs under the current framework, particularly around white paper requirements, operational reporting, or capital thresholds for smaller CASPs, the consultation is the formal channel to raise those concerns. Submissions close on 31 August 2026 via the Commission's online questionnaire.
Practical Steps for Firms Before the Deadline
Internal Impact Assessment
Map your client book against the areas under review. Clients that are ART or EMT issuers, CASPs, DeFi-adjacent businesses, or NFT platforms face the highest potential for regulatory change. For each, document the current accounting treatment and identify which policy decisions rest on assumptions that a revised MiCA could disturb.
Engagement with the Consultation
Accounting and audit firms are legitimate stakeholders in this process. If your practice has direct experience of how current MiCA requirements interact with IFRS or audit standards, submitting a response adds sector-specific evidence to the Commission's assessment. Industry bodies including ICAEW, FEE, and the IASB's consultative processes are also likely to coordinate responses; aligning with those submissions can amplify firm-level input.
Client Communication
Clients with significant MiCA obligations need to know that the framework they are currently complying with may change materially. Proactive communication, framed around the specific areas that affect each client's business model, demonstrates the advisory value that distinguishes compliance-focused firms. Do not wait for a legislative proposal to start those conversations.
Frequently Asked Questions
What is the deadline for responding to the MiCA review consultation?
The European Commission's online questionnaire closes on 31 August 2026. Submissions from accounting firms, auditors, and other professional stakeholders are welcomed as part of the evidence-gathering process.
Does the consultation mean MiCA will definitely be amended?
Not necessarily. The consultation is mandated by Articles 140 and 142 of MiCA and feeds into a Commission report to the European Parliament and Council. That report may, but does not have to, be accompanied by a legislative proposal. The breadth of the questions does indicate that amendment is being seriously considered, but the outcome will depend on the evidence gathered and political priorities at the time.
How does a potential MiCA revision affect stablecoin accounting under IFRS?
ART and EMT reserve requirements are explicitly under review. Any change to reserve eligibility, redemption mechanics, or capital buffers would require issuers to reassess the classification and measurement of reserve assets under IAS 32 and IFRS 9, and potentially revisit the liability classification of the tokens themselves. IFRS preparers should document their current accounting policy rationale now so that any required changes can be identified quickly once a legislative proposal is published.
What does the DeFi section of the consultation mean for auditors?
The Commission is asking whether CASPs should conduct due diligence over DeFi protocols they connect clients with and whether smart contract certification schemes are warranted. If either becomes a regulatory requirement, it could create new categories of assurance engagement. Audit firms should start developing methodology for assessing DeFi protocol due diligence and reviewing smart contract audit outputs before any final rules require them to do so.
Should accounting firms submit a response to the consultation?
Yes, where they have relevant practical experience. The Commission is seeking data and views on MiCA's application. Accounting and audit firms have direct evidence of how current requirements interact with IFRS, audit standards, and client operations. Coordinating with professional bodies such as ICAEW or FEE can strengthen the sector's collective input.
