On March 27, 2026, Luxembourg published the Law of 27 March 2026 relating to the automatic and mandatory exchange of information declared by crypto-asset service providers, transposing Directive (EU) 2023/2226 into domestic law. This legislation sets out detailed reporting obligations for crypto-asset service providers (CASPs) operating in Luxembourg, and establishes processes for the automatic exchange of information with other jurisdictions. It sets out the registration procedures for CASPs, as well as the information that the Commission de surveillance du secteur financier (CSSF) must communicate annually to the Direct Tax Administration. This includes the identity of all CASPs holding authorisation in Luxembourg, along with their legal entity identifiers and commercial registry numbers. CASPs are required to register with the Direct Tax Administration and provide detailed information, including their name, postal address, email addresses, tax identification numbers and the jurisdictions in which their reportable users reside. They are also required to implement due diligence procedures to identify reportable users and maintain records for ten years. They must collect and report comprehensive transaction data, including acquisition and disposal amounts, units transferred, fair market values and payment method details. The reporting deadline is set for June 30 each year, with initial reporting covering the 2026 calendar year onwards. The law also sets out the procedures for the Direct Tax Administration to communicate information, and it will exchange reported information with the competent authorities in other jurisdictions by September 30 each year. Penalties for non-compliance range from €5,000 for registration failures to €250,000 for breaches of due diligence and reporting obligations. The law also amends related legislation on administrative fiscal cooperation, common reporting standards, country-by-country reporting and cross-border arrangements. The law applies from January 1, 2026, with registration requirements taking effect from that date.
