Crypto exchanges now report to Revenue: what the new EU rules mean for you
Last updated 16 October 2026
Since 1 January 2026, crypto exchanges collect your tax details and transactions. The first reports go to Revenue by 31 May 2027 and abroad by 30 September.
Crypto has moved into the same automatic reporting that already covers bank accounts and shares. The Crypto-Asset Reporting Framework (CARF) was agreed through the OECD (Organisation for Economic Co-operation and Development). The EU brought it into law through a directive known as DAC8 (the eighth update to the EU's tax cooperation rules). It requires crypto exchanges and brokers to report their customers' transactions to tax authorities. In Ireland the rules apply from 1 January 2026.
Who reports
‘Reporting crypto-asset service providers’: firms that buy, sell or transfer crypto-assets for customers, or carry out retail payments in crypto. That covers the exchanges and apps most people use. Listed companies, governments, central banks and some financial institutions are not reported on as users.
What they ask you for
As an individual customer you must give the provider your:
- name and main address;
- country of tax residence;
- tax identification number;
- date and place of birth.
Businesses give their details and those of the people who control them.
What gets reported
For each type of crypto-asset, over the calendar year:
- what you paid and received for purchases and sales, the number of units and the number of transactions;
- transfers in and out, with amounts, units and number of transactions;
- payments to merchants that count as reportable retail payments, at market value.
The timetable
| Date | What happens |
|---|---|
| 1 January 2026 | Providers start collecting information on customers and transactions |
| 31 May 2027 | Providers report 2026 to Revenue, and must give you a copy of what they reported about you |
| 30 September 2027 | Revenue exchanges the information with other EU countries and CARF jurisdictions |
The same cycle repeats each year. You may use an exchange based in another EU country or CARF country. Then that country's tax authority sends your information to Revenue in the same way.
What it means for you
The tax rules haven't changed: selling, swapping or spending crypto is usually a disposal for CGT (see crypto tax). What changes is that Revenue will see your activity without relying on your return. So:
- make sure each year's disposals, including losses, are on your return;
- keep your own records of cost, dates and euro values for six years, since a provider's totals show amounts, not your gain;
- check the copy you receive by 31 May 2027 against your records, and ask the provider to correct anything wrong.
The legal basis is section 891HA of the Taxes Consolidation Act 1997, inserted by Finance Act 2025, and section 891M. Revenue's guidance is on its CARF and DAC8 pages, including the information users must give.
