As of January 2026, Luxembourg's landmark carried interest tax regime (Bill 8590) is officially live. For independent fund managers, boutique AIFMs, and consultants relocating from the UK, USA, or Switzerland, this represents a transformational opportunity. Qualifying professionals can now benefit from carried interest taxed at just one-quarter of the standard rate — a decisive competitive advantage for Luxembourg as a fund domicile. In this article, we explain who qualifies, what the structuring requirements look like, and how Neomondo Capital can act as your local director to navigate the certification process with the Luxembourg tax authorities.

Why This Regime Changes Everything

For decades, Luxembourg has been the undisputed capital of European fund structuring. Over 4,500 funds are domiciled here, managing in excess of €5 trillion in assets. Yet despite this dominance in fund administration, Luxembourg had historically struggled to attract the fund managers themselves — the GPs, CIOs, and portfolio managers who make the actual investment decisions.

The reason was simple: the tax treatment of carried interest — the performance-linked compensation that is the lifeblood of private equity, venture capital, and hedge fund economics — was not competitive. Managers paid standard income tax rates on their carry, making Luxembourg significantly less attractive than London, Zurich, or even Dublin for the actual human talent running the funds.

Bill 8590 changes this entirely. By taxing qualifying carried interest at one-quarter of the standard Luxembourg income tax rate — effectively capping the tax burden at approximately 10–11% for most qualifying individuals — Luxembourg has repositioned itself not just as a fund domicile, but as a genuine home for the fund managers themselves.

The timing is deliberate. With UK non-dom tax advantages being dismantled and Swiss competition intensifying, Luxembourg has moved decisively to capture a generation of relocating investment professionals.

Who Qualifies for the Reduced Rate?

The regime is not universally available. The Luxembourg legislature has defined qualifying criteria carefully to ensure the benefit is targeted at genuine investment professionals adding real economic value — not at passive recipients of performance fees.

To qualify for the reduced carried interest tax rate, an individual must generally meet the following conditions:

Professional Activity in Luxembourg
The individual must be actively employed or engaged as a self-employed professional in Luxembourg and must perform their investment management activities — deal sourcing, portfolio monitoring, investment committee participation — predominantly from Luxembourg. Remote management from another jurisdiction does not qualify.

Qualifying Fund Structures
The carried interest must derive from a qualifying alternative investment fund structure, such as a Reserved Alternative Investment Fund (RAIF), a Specialised Investment Fund (SIF), or an authorised Alternative Investment Fund managed by a regulated AIFM. Standard corporate holding structures or unregulated vehicles do not qualify.

Genuine Performance-Linked Compensation
The carried interest must represent genuine performance compensation — a share of profits above a defined hurdle rate, distributed after the return of investor capital. Management fees, advisory retainers, or fixed compensation re-labelled as carry do not qualify and will be challenged by the tax authorities.

Minimum Holding or Vesting Period
The regime requires that the carried interest is subject to a minimum holding or vesting period, confirming that it reflects long-term value creation rather than short-term fee income. The specific period must be documented in the fund's legal agreements.

Tax Residency in Luxembourg
The individual must be a Luxembourg tax resident for the year in which the carried interest is received. Individuals who receive carry while resident in another country cannot retrospectively claim the reduced rate for that distribution.

What Does the Structuring Look Like?

Qualifying for the regime is not simply a matter of relocating to Luxembourg and declaring your carried interest. The structuring must be correct from the outset, and the certification process with the Luxembourg tax authorities — the Administration des Contributions Directes (ACD) — requires careful preparation.

Step 1 — Fund Structure Review
The first step is confirming that your existing or planned fund vehicle qualifies under the regime. If your fund is currently domiciled outside Luxembourg — in the Cayman Islands, Delaware, or the Channel Islands — a restructuring or parallel Luxembourg vehicle may be required. This is a legal and tax advisory exercise that our partner network of Luxembourg law firms and tax advisors can execute efficiently.

Step 2 — Employment or Service Agreement Structuring
Your contractual relationship with the Luxembourg management entity must accurately reflect your role and responsibilities. The agreement must clearly define your investment management duties, your entitlement to carried interest, the vesting schedule, and the hurdle rate. Poorly drafted agreements are the most common reason carry claims are challenged during tax audits.

Step 3 — Luxembourg Entity Setup
Most qualifying managers will require a Luxembourg management company or General Partner entity through which their investment activities are conducted. This entity must have genuine substance — a registered address, operational bank account, and demonstrable management activity taking place on the ground. This is precisely where Neomondo Capital's Setup & Governance services become critical.

Step 4 — ACD Certification Application
The Luxembourg tax authorities issue a formal certification confirming that a specific carried interest arrangement qualifies for the reduced rate. This application requires a comprehensive submission including the fund's constitutional documents, the manager's service or employment agreement, evidence of Luxembourg tax residency, and a detailed description of the investment activities performed locally. Errors or omissions in this submission can result in delays or rejection — and a rejected application creates complications for future distributions.

Step 5 — Ongoing Compliance
The reduced rate is not a one-time approval. Each year, the manager must demonstrate continued compliance with the qualifying criteria — active local management, maintained tax residency, and distributions that remain genuinely performance-linked. Annual board minutes, investment committee records, and travel logs are all relevant evidence in the event of a compliance review.

The Luxembourg Advantage: A Comparative View

To understand why Bill 8590 is so significant, it helps to compare Luxembourg's new position against its principal competitors for relocating fund talent.

United Kingdom
The UK's non-dom regime — long a primary attraction for international fund managers — has been progressively dismantled since 2024. Carried interest in the UK is now taxed at 32%, following the removal of the favourable capital gains treatment that previously applied. For UK-based managers, Luxembourg now offers a dramatically lower effective tax rate on carry, combined with EU market access that post-Brexit London can no longer provide.

Switzerland
Switzerland remains attractive for its overall tax environment and quality of life, but Swiss cantonal tax rates on carried interest vary significantly and can reach 30–35% in financial centres like Zurich and Geneva. Luxembourg's flat, predictable reduced rate offers greater certainty for structuring purposes.

Ireland
Ireland has a carried interest regime but caps the benefit at a relatively narrow set of structures and applies it at an effective rate that is broadly comparable to Luxembourg's new offering. Luxembourg's advantage lies in the depth of its fund ecosystem — administrators, custodians, law firms, and regulators — which Ireland cannot yet match at scale.

United States
For US managers with non-US funds, the Luxembourg regime offers a compelling European base for managing global capital. Combined with Luxembourg's extensive double tax treaty network — one of the broadest in the world — and EU fund passport access, Luxembourg is increasingly the preferred domicile for US managers expanding into European investor markets.

The Role of a Local Director in the Certification Process

One of the most practical challenges that relocating fund managers face is the ACD certification process itself. The Luxembourg tax authorities are experienced and thorough. They expect submissions to be professionally prepared, structurally coherent, and supported by evidence of genuine local activity.

A credible local director — one with an established track record in Luxembourg fund structures and existing relationships with the relevant tax and regulatory authorities — plays a pivotal role in this process.

At Neomondo Capital, when we act as your local director or General Partner board member, we provide more than a signature on your constitutional documents. We actively support the preparation of your ACD certification submission, coordinate with your legal and tax advisors to ensure the documentation package is complete and coherent, and represent your structure's operational credibility to the authorities.

Equally important, we ensure your entity maintains the ongoing substance standards that underpin the certification year after year — board meetings properly documented, investment decisions formally recorded, and local management activity demonstrably taking place in Luxembourg.

Is This Regime Right for You?

Bill 8590 is most immediately relevant to four categories of investment professional:

Independent Fund Managers launching new vehicles who have flexibility in choosing their domicile and management location. For this group, Luxembourg is now the optimal choice across tax, regulatory access, and fund ecosystem depth.

Existing managers at larger institutions who are considering a spin-out or establishing an independent GP. The carried interest regime makes Luxembourg a compelling home base for the new entity, particularly when combined with an existing investor base in Europe.

UK-based managers facing the full impact of the removal of non-dom benefits and the increased carried interest tax rate, for whom a strategic relocation to Luxembourg represents a straightforward and significant financial improvement.

US and Swiss managers expanding their European investor coverage and seeking a credible, tax-efficient base from which to manage EU-focused or global strategies.

If you fall into any of these categories, the practical next step is a structuring consultation to assess whether your current or planned fund vehicle qualifies, what entity setup is required, and what timeline is realistic for ACD certification.

The Bottom Line

Luxembourg's carried interest tax regime is the most significant development in European fund management since the introduction of the AIFMD. For qualifying professionals, it fundamentally changes the financial calculus of where to base your management activities — and Luxembourg's answer is now definitively competitive with any jurisdiction in the world.

The window to act is open, but the advantage belongs to those who structure correctly from the outset. An incorrectly established entity, a poorly drafted service agreement, or a rushed ACD application can forfeit the benefit entirely.

Neomondo Capital provides end-to-end support for fund managers establishing their Luxembourg presence: from entity setup and banking access to resident directorship, ACD certification support, and ongoing governance. We act as your local operator on the ground — so you can focus on managing your fund.
