Luxembourg has introduced targeted reforms to its carried interest tax regime, with the updated rules applying to income realised from 1 January 2026. The changes form part of a broader effort to reinforce Luxembourg’s position as a leading European jurisdiction for alternative investment structures, while addressing practical limitations that had emerged under the previous framework.
At a high level, the revised regime seeks to achieve two objectives. First, it provides greater legal certainty around the tax treatment of carried interest. Second, it aligns more closely with the commercial realities of how carried interest is structured and allocated in the market today.
A clearer distinction between forms of carried interest
A notable feature of the reform is the express distinction between contractual carried interest and participation-linked carried interest.
Contractual carried interest refers to arrangements where remuneration is granted purely on a contractual basis, without a requirement for the recipient to hold an equity interest in the underlying fund. Such income is treated as extraordinary income and benefits from a reduced effective tax rate, achieved by applying taxation at one quarter of the applicable progressive rate.
By contrast, participation-linked carried interest is tied to a direct or indirect investment in the fund. Under the revised rules, the portion of returns attributable to outperformance may be exempt from Luxembourg personal income tax, subject to certain conditions, notably a minimum holding period of six months and a threshold limiting participation to less than 10% of the fund’s equity.
This distinction brings welcome clarity and reflects structures commonly seen across private equity and alternative asset strategies, where both contractual and equity-based incentive mechanisms are used.
Broader eligibility, but with a clear boundary
The reforms also expand the category of individuals who may benefit from the regime. Previously focused on employees of fund managers, the scope now extends to Luxembourg tax-resident individuals actively involved in the management of alternative investment funds, including those operating through advisory or service arrangements.
This is a meaningful development. It recognises that fund management functions are often carried out across a broader ecosystem, including independent advisers and professionals operating through corporate structures. Bringing these individuals within scope aligns the tax treatment more closely with how investment teams are structured in practice.
That said, the legislation draws a clear line between those engaged in active management and those performing purely administrative functions. Only the former are intended to benefit, preserving the policy intent of the regime as an incentive for investment decision-makers rather than operational support roles.
Removal of structural constraints
Another practical change is the removal of the requirement for investors to have fully recovered their capital before carried interest can be paid. This effectively formalises the acceptability of “deal-by-deal” carry models.
This adjustment is significant. While deal-by-deal waterfalls have become more common in fund structures, the previous Luxembourg framework was more closely aligned with whole-fund distribution models. The reform brings the tax treatment into line with current market practice and allows for greater flexibility in structuring incentive arrangements.
Territorial scope
The regime continues to apply only to Luxembourg tax-resident individuals. It does not extend tax benefits to non-resident carried interest recipients, even where the underlying fund is established in Luxembourg.
From a structuring perspective, this reinforces the importance of carefully considering the location of investment professionals and the interaction with other jurisdictions’ tax rules.
A more competitive offering
Taken together, the changes represent a pragmatic evolution rather than a wholesale redesign. The regime is broader in scope, more flexible in application and more closely aligned with prevailing market standards.
In particular, the combination of reduced taxation for contractual carry and potential exemption for qualifying participation-linked returns places Luxembourg in a competitive position relative to other European jurisdictions. At the same time, the framework retains sufficient guardrails to ensure that the regime is targeted towards individuals with a genuine role in investment decision-making.
From a structuring standpoint, the revised regime should allow for greater consistency between legal design, commercial intent and tax outcome. For fund managers and sponsors operating across multiple jurisdictions, that alignment is often as important as the headline tax rate.
Conclusion
The revised carried interest regime is best understood as part of Luxembourg’s broader proposition as a European hub for alternative investment activity. It complements an already well-established legal and regulatory framework, while addressing specific friction points that had emerged in practice.
For managers considering the location of future structures, or revisiting existing arrangements, the updated rules merit close attention. The regime does not fundamentally change the principles of carried interest taxation, but it does provide a more workable and predictable framework within which those principles can be applied.
