Selling on a Non-EU Exchange: Irish CGT and DAC8

Updated 17 October 2026 · Information only · Not tax or financial advice

Short answer: Revenue's crypto manual says section 29 TCA 1997 is the CGT charging section and that a person resident or ordinarily resident in the State is chargeable on gains accruing in a year of assessment (subsection (2)). The pages we read tie the charge to residence and domicile, not to the location of the exchange. Separately, Revenue says the Crypto-Asset Reporting Framework (CARF), implemented in the EU by DAC8, applies from 1 January 2026: reporting crypto-asset service providers collect user and transaction data from that date, file the first returns by 31 May 2027, and Revenue exchanges the data with other jurisdictions by 30 September 2027 (Revenue DAC8 page and eBrief 121/26). The 2026 data will therefore start reaching tax authorities in 2027.

What this means

• Using an exchange outside the EU does not, on these pages, change whether an Irish-resident taxpayer must declare a gain (dates).
• Revenue's DAC8 pages say providers with a nexus to Ireland register with Revenue, and that CARF has a hierarchy to avoid duplicate reporting; Revenue's registration page says providers with multiple nexuses at the same level are not required to report in Ireland if they report in another Member State or a Qualified Non-Union Jurisdiction.
• Revenue's DAC8 page says reporting crypto-asset service providers (RCASPs) with an Irish nexus (for example Irish residence, incorporation, management, a regular place of business or a branch, or Irish MiCA authorisation) must register with Revenue for CARF, and that a nexus hierarchy avoids duplicate reporting. It does not say whether a particular non-EU exchange reports. The EU directive itself (Directive (EU) 2023/2226, article 8ad(7) and Annex VI) requires a crypto-asset operator to register in one Member State and defines a "Reportable User" as a customer resident in a Member State; an operator may be exempt for a user if it reports that user in a non-EU jurisdiction that has a qualifying agreement with the user's Member State (Annex VI, section II.E). Whether a specific non-EU exchange has registered or is in a qualifying jurisdiction is not something we could check.
• Non-domiciled individuals: the remittance basis applies only to assets "situated outside the State", and Revenue says a crypto-asset that exists "on the cloud" is not situated anywhere, so it cannot be viewed as outside the State (non-dom page).

Practical points (our suggestion)

Keep your own records whichever exchange you use (records); if you have not declared past gains, see qualifying disclosure.

Made-up example

An Irish resident sells coins on an exchange based outside the EU in 2026 and makes a gain. The gain is declared on the CGT return in the usual way; an exchange within CARF scope would report the 2026 transaction by 31 May 2027.

FAQ

Does DAC8 create a new tax?

No; it is a reporting framework.

Does using a non-EU exchange avoid DAC8?

Not necessarily. The directive covers operators that serve customers resident in a Member State, wherever the operator is based; check whether your exchange has said it reports under CARF/DAC8.

Do I have to wait for an exchange report before declaring?

No. Revenue's crypto manual says Ireland operates self-assessment and the responsibility for filing a return rests with the taxpayer (TDM 02-01-03, section 1.4).
