The DAC8 cross-border reporting obligation is retained at Probable confidence (downgraded from Confirmed, single T4 source); core Irish CGT/income-tax treatment of crypto-assets could not be substantiated against a primary Revenue source this cycle and has been routed to the gaps register (crypto-int-3, crypto-int-4).
Two related findings were removed from structured claims entirely this cycle rather than asserted on thin evidence. No primary Revenue Commissioners source was located confirming Capital Gains Tax treatment, cost-basis rules, or the characterisation of crypto-asset disposals for Irish tax residents; this has been routed to the gaps register pending a Revenue Tax and Duty Manual or eBrief. Similarly, no primary Revenue guidance was located confirming income-tax characterisation, valuation, or timing treatment of crypto-asset income such as mining or staking rewards; this finding was removed from structured claims this cycle specifically because it lacked any primary source and functioned as a sourcing gap rather than a genuine in-force assertion, and has likewise been routed to the gaps register.
The practical effect is that Ireland's cross-border crypto tax reporting obligation is documented, if only at Probable confidence, while the more fundamental question of how Irish tax law actually treats crypto-asset gains and income for ordinary taxpayers remains an open sourcing gap rather than a settled finding. The supervisory authority of record for this module is the Office of the Revenue Commissioners, distinct from the Central Bank of Ireland that anchors the other modules.
Outlook
Closing the Revenue Commissioners sourcing gap is the clearest priority for this module going forward: locating a Tax and Duty Manual or eBrief addressing capital gains and income tax treatment of crypto-assets would allow both gaps-register items to convert into sourced findings and would materially improve this module's confidence profile. Corroborating the DAC8 reporting obligation against the Council Directive text itself, rather than trade-press coverage alone, would similarly allow that finding's confidence to be restored toward Confirmed.
Tax Treatment
Ireland's crypto-asset tax reporting framework now operates under a confirmed statutory basis. TCA 1997 s.891M, inserted by S.I. No. 584 of 2025, gives domestic effect to DAC8/CARF and requires a Reportable Crypto-Asset Service Provider to report details of relevant transactions to Revenue by 31 May of the year following the reportable calendar year. The same provision requires the RCASP to provide the crypto-asset user with a copy of that reported information by the same 31 May deadline. Revenue then exchanges the reported data with partner tax administrations in other jurisdictions by 30 September of that year. This is confirmed directly from Revenue's own published DAC8 guidance, and the regime has applied from 1 January 2026.
The structure mirrors the broader OECD Crypto-Asset Reporting Framework rollout: a reporting entity (the RCASP) owes two obligations on the same date, one to the tax authority and one to its own user, before a cross-border exchange step follows roughly four months later. For an RCASP established or operating in Ireland, this converts crypto-asset transaction data into an annual compliance deliverable with a fixed calendar, rather than a matter handled on an ad hoc or enforcement-driven basis.
Outlook
The first full reporting cycle under this regime, with the 31 May deadline for the 2026 reportable year, will be the first practical test of how RCASPs operating in Ireland handle the dual reporting-to-Revenue and reporting-to-user obligation, and of how Revenue manages the subsequent cross-border exchange by 30 September. Until that cycle completes, the framework stands as a confirmed but not yet operationally tested obligation.

Tax Treatment
The EU's DAC8 directive entered into force on 1 January 2026, establishing an EU-wide reporting architecture for Reporting Crypto-Asset Service Providers. Reporting is due within nine months after the end of the first fiscal year covered by the directive, which places the filing window for the 2026 reporting year between 1 January and 30 September 2027. This corrects an earlier intake claim that had placed the relevant deadline at 31 May 2027; the corrected window is drawn directly from the European Commission's own published DAC8 materials.
For crypto-asset service providers operating in Ireland, this EU-wide reporting obligation applies as directly-applicable law flowing from the directive's transposition requirements. The Revenue Commissioners' own administrative filing deadline, which may sit anywhere within the EU's nine-month outer limit rather than necessarily coinciding with its final day, was not independently confirmed this cycle. This is a research gap rather than a finding that no Irish-specific administrative deadline exists; firms should not assume the EU outer limit and any eventual Irish administrative deadline are the same date.
No Irish-specific penalty regime or enforcement posture for DAC8 non-compliance was located this cycle. The directive's entry into force on 1 January 2026 is itself the material event for this reporting cycle; the substantive compliance burden, in the form of the first reporting obligations, falls due in the 2027 window described above.
Outlook
The period between 1 January 2027 and 30 September 2027 is the dated marker for the first DAC8 reporting cycle covering the 2026 fiscal year. Reporting Crypto-Asset Service Providers in Ireland should treat the Revenue Commissioners' eventual publication of its own administrative deadline, whenever that occurs, as the operative date for their own internal planning, rather than defaulting to the EU's nine-month outer limit as if it were the Irish deadline itself.
