What the law does

Published in the Mémorial on 27 March 2026, the law requires crypto-asset service providers to collect and report information on their users’ crypto-asset transactions, for exchange with other EU tax authorities. A grand-ducal regulation of 18 May 2026 sets the registration and reporting forms.

Who reports

• Crypto-asset service providers authorised under MiCA.
• Other crypto-asset operators with a sufficient nexus to Luxembourg, which must register with the tax authorities.

Deadlines and penalties

• Calendar year 2026 is the first reporting year; reports are due by 30 June 2027 and every 30 June after.
• A nil return is needed if there are no reportable users.
• EUR 5,000 fixed fines for registration failures and late filing.
• Fines up to EUR 250,000 for other due diligence or reporting breaches found on audit.

Other changes in the same law

• CRS deposit accounts now include electronic money and central bank digital currencies held for clients.
• Tax rulings for individuals are exchanged where the transaction exceeds EUR 1.5 million or the ruling decides tax residence, for rulings from 1 January 2026.
• Country-by-country reports must include each entity’s tax identification number from fiscal years beginning on or after 1 January 2028.

What to do now

• Crypto businesses: confirm registration and build user self-certification into onboarding.
• Banks and e-money institutions: update CRS due diligence for e-money accounts.
• Individuals with Luxembourg rulings above EUR 1.5 million: expect exchange with home countries.

Our take

Crypto holdings are joining bank accounts in the automatic exchange net. Gulf investors using EU platforms should assume their tax residence country will receive the data.
