CARF and DAC8 reporting in Ireland
Ireland applies CARF through the EU's DAC8 directive, and Reporting Crypto-Asset Service Providers report to Revenue. The obligations apply from 1 January 2026, you register before 31 December in the year you become an RCASP, and your first report is due by 31 May 2027. Revenue has set specific penalties and a dedicated registration portal, so the detail matters. Kryptos does the due diligence, builds the file, and files it.
Who is an RCASP in Ireland
Two routes bring you in. Any crypto-asset service provider authorised under MiCAR in Ireland is an RCASP, and so is any other crypto-asset operator with an Irish or EU nexus, even without MiCAR authorisation. You register with Revenue before 31 December in the year you become an RCASP, through a dedicated portal Revenue is launching before the end of 2026, not through ROS. Being unregulated as a CASP does not put you outside the rules.
The dates that matter
The obligations apply from 1 January 2026, and the first reportable period is the 2026 calendar year. You collect self-certifications from pre-existing users by 31 December 2026 and from new users as they onboard. The first return is due to Revenue by 31 May 2027, Revenue exchanges the data with other jurisdictions by 30 September, and you keep the due-diligence records for six years.
What you report
You report users who are resident in Ireland, in another EU member state, or in a listed reportable jurisdiction. The reportable transactions are crypto-to-fiat, crypto-to-crypto, transfers, and retail payments for goods or services above USD 50,000, aggregated per user and per crypto-asset. It is information reporting, not withholding: you report the data, and working out the tax stays with the user.
The penalties Revenue has set
Unlike some member states, Ireland has published the figures. Failing to file, or filing an incorrect or incomplete return, carries a €19,045 penalty, with €2,535 for each day a return stays outstanding. Failing to register or to apply the due-diligence procedures is €4,000, and not complying with an authorised officer is €1,265. Registration IDs can also be revoked. Clean self-certification from the start is what keeps you clear.
How Kryptos handles it
It runs on one system. You send your own transaction and account data, Kryptos collects self-certifications and checks tax IDs at onboarding, works out gains on the right basis, and builds the exact file the authority accepts, checked against the schema before you submit.
