The Luxembourg law of 27 March 2026 on the automatic and mandatory exchange of information reported by Crypto‑Asset Service Providers implements Directive (EU) 2023/2226 (“DAC 8”). DAC 8 extends the European framework for administrative cooperation in tax matters to the universe of crypto‑assets, notably through the automatic exchange of information between tax authorities. This development forms part of a broader European effort to structure and regulate the crypto ecosystem. It strengthens the existing legal framework and complements Regulation (EU) 2023/1114 on markets in crypto‑assets (“MiCAR”), by adding a crucial dimension of tax transparency and traceability.Beyond these two European instruments, Luxembourg also relies on a national tax framework applicable to virtual currencies, primarily based on an administrative circular issued in 2018, which continues to play a central role in practice for determining the income tax treatment of crypto‑asset transactions.

What are the implications of MiCAR in the Luxembourg context?

With the MiCAR Regulation (Regulation (EU) 2023/1114), which became fully applicable at the end of 2024, the European Union has introduced a common regulatory framework covering both the issuance of crypto‑assets and the provision of crypto‑asset services. MiCAR notably establishes an authorisation and supervisory regime for crypto‑asset service providers (“ CASPs ”), transparency obligations for issuers (including the publication of white papers), as well as governance and conduct rules broadly comparable, in their underlying rationale, to those applicable to traditional financial market participants.

In Luxembourg, the CSSF is the competent authority. Presently, MiCAR constitutes the core regulatory framework applicable to crypto‑assets in Luxembourg, supplemented by national regulatory guidance and a significant body of European‑level guidelines, but without directly addressing tax matters, which fall under separate instruments such as DAC 8.

Does DAC 8 mean the end of tax opacity for crypto-assets?

With the adoption and implementation of DAC 8, the European Union has taken a decisive step by bringing crypto‑assets within the scope of automatic exchange of tax information, following the model long applied to financial accounts under the Common Reporting Standard (“ CRS ”). DAC 8 constitutes the EU implementation of the OECD Crypto‑Asset Reporting Framework (“ CARF ”) and aims to reduce the information asymmetry that historically characterised crypto‑asset transactions, whereby transactional information was available to taxpayers and crypto‑asset platforms but not to tax authorities, particularly in cases involving foreign platforms or cross‑border activities. By introducing systematic reporting obligations, DAC 8 seeks to ensure that tax authorities receive relevant transactional data, in a manner comparable to the automatic exchange of information applicable to financial accounts under the CRS.

In Luxembourg, DAC 8 and the introduction of a crypto‑asset reporting framework was implemented through the law of 27 March 2026, applicable as from 1 January 2026, which imposes structured obligations on CASPs and equivalent operators in terms of due diligence, data collection and reporting. In practice, CASPs are required to identify their users through self‑certifications, collect detailed transactional data (crypto‑to‑fiat, crypto‑to‑crypto, transfers and payments), and report this information annually to the Luxembourg tax authorities, which subsequently exchange it automatically with the tax authorities of the relevant jurisdictions of residence. The first reports will be submitted in 2027 for the 2026 reporting period, within a framework that includes a graduated sanctions regime and mechanisms designed to avoid double reporting within the European Union.

DAC 8 does not introduce a new tax on crypto-assets, as taxation remains a national competence, but it significantly reshapes the level of tax control. Crypto-assets thereby leave the grey area of limited transparency and become subject to a degree of traceability comparable to that applicable to traditional financial assets. In this respect, DAC 8 complements MiCAR: while MiCAR governs market access and regulatory supervision of crypto actors, DAC 8 represents its tax counterpart, providing tax authorities with the tools necessary to verify the correct application of existing tax rules.

What is the tax treatment of virtual currencies in Luxembourg?

From the perspective of the tax treatment of virtual currencies as such, Luxembourg has not enacted specific tax legislation dedicated to crypto‑assets. The applicable framework still primarily relies on two circulars, i.e., the Circular L.I.R. No. 14/5 – 99bis/3 of 26 July 2018 regarding the direct tax aspects (“ Circular 14/5 ”) and the Circular No. 787 of 11 June 2018 in relation to the VAT aspects (“ Circular 787 ”).

The Circular 14/5 characterises virtual currencies as intangible assets, rather than official currency (e.g., EUR), meaning that currency exchange gain or loss treatment does not apply. As such, the taxation of this asset follows the general income tax rules applicable to assets, which depends on the nature of the activity and the taxpayer's profile. For individuals, the key distinction remains that between private wealth management and professional activity. Gains arising from the disposal or exchange of crypto‑assets held for private purposes may qualify as speculative income where the transaction occurs within six months of acquisition, and are then taxable according to the progressive income tax scale, although gains not exceeding the aggregate annual exemption threshold of EUR 500 are exempt. Conversely, gains realised after a holding period exceeding six months are, in principle, tax‑exempt. Where the activity presents the characteristics of a commercial activity — notably the frequency of transactions, the use of borrowed capital, a structured organisation or transactions carried out on behalf of third parties — income derived from crypto‑assets falls under business profits and is taxed in accordance with ordinary tax rules, including income derived from activities such as mining or certain forms of staking (i.e. the locking or delegation of crypto‑assets to a blockchain network in exchange for rewards).

For Luxembourg partnerships (e.g., SCS, SCSp), which are in principle tax-transparent and therefore not subject to taxation, particular attention must be paid to the nature of the activity carried out. Where the activity of the partnership goes beyond the mere holding of virtual currencies (e.g., active trading, mining, etc.), its activity may be qualified as commercial, triggering taxation from a municipal business tax perspective, unless the partnership is organised as an investment fund.

Luxembourg commercial companies (e.g., S.A. or S.à r.l.), by contrast, are deemed to carry on a commercial activity by nature. As a result, income and capital gains derived from transactions involving virtual currencies are in principle fully taxable under ordinary corporate income tax rules, unless such companies benefit from a specific status (e.g., investment funds or private wealth management companies).

From a VAT perspective, Circular 787 clarifies that VAT exemption applies to exchange transactions involving virtual currencies used as a means of payment. This VAT exemption does not, however, extend to other crypto‑related services, including advisory or custody services, which remain taxable.

The adoption of MiCAR and the implementation of DAC 8 have not altered these substantive tax rules applicable to virtual currencies. They have, however, significantly strengthened their practical enforcement. MiCAR structures and supervises the crypto market ecosystem, while DAC 8 introduces a comprehensive framework for tax transparency and automatic exchange of information, granting tax authorities access to data that was previously difficult to verify. As a result, while the Luxembourg tax treatment of virtual currencies has remained formally unchanged since 2018, it now operates within a far more robust regulatory and reporting environment, making the tax qualification and proper documentation of crypto-asset transactions more critical than ever.
