Ireland QIAIF: The Alternative Investment Fund for EU Institutional Investors

Ireland's Qualifying Investor AIF: An Institutional-Grade Platform

The Qualifying Investor Alternative Investment Fund (QIAIF) is Ireland's flagship vehicle for alternative investment strategies. Authorised by the Central Bank of Ireland (CBI) under the Irish AIFMD framework (European Union (Alternative Investment Fund Managers) Regulations 2013, S.I. No. 257 of 2013), the QIAIF is designed for professional and qualifying investors who meet minimum subscription thresholds.

Ireland has established itself as Europe's largest domicile for alternative investment funds, with over EUR 900 billion in net assets under management in Irish-authorised AIFs. The QIAIF sits at the centre of this ecosystem, supported by a deep bench of administrators, depositaries, legal counsel, and audit firms.

Investor Eligibility and Minimum Subscription

The QIAIF is restricted to qualifying investors, defined as:

• Professional investors within the meaning of MiFID II Annex II
• Investors who can make a minimum initial subscription of EUR 100,000 (or its equivalent in another currency)
• Investors who certify that they are aware of the risks involved and are capable of bearing those risks

Unlike the Luxembourg RAIF's EUR 125,000 threshold, the QIAIF's EUR 100,000 minimum subscription is imposed by the CBI's AIF Rulebook and cannot be waived by the fund's documentation. The minimum applies per investor, per fund.

Legal Structures Available

A QIAIF can be established as:

• ICAV (Irish Collective Asset-management Vehicle): The most popular structure, introduced by the Irish Collective Asset-management Vehicles Act 2015. The ICAV is purpose-built for investment funds, avoids company law requirements that are irrelevant to funds, and can elect to be treated as a partnership or transparent entity for US tax purposes (by "checking the box")
• Unit Trust: A contractual arrangement governed by a trust deed between the management company and the trustee/depositary
• Investment Limited Partnership (ILP): Used for closed-ended private equity and venture capital strategies, following amendments to the Investment Limited Partnerships Act 1994 (as amended in 2020)
• PLC or DAC: A public limited company or designated activity company — less common due to heavier company law requirements

The ICAV has become the dominant structure, accounting for the majority of new QIAIF launches since 2015. Its ability to check the box for US tax purposes makes it particularly attractive for funds seeking US taxable investor capital without the need for a Delaware feeder.

CBI Authorisation Process

Unlike the Luxembourg RAIF, the QIAIF requires prior authorisation from the Central Bank of Ireland. However, the CBI operates a fast-track authorisation process for QIAIFs:

• 24-hour approval: Available for QIAIFs that use a pre-approved AIFM, depositary, and legal documentation that conforms to CBI templates. The fund can be authorised within one business day of filing
• Standard approval: 2–4 weeks for QIAIFs that require CBI review of non-standard provisions

The 24-hour approval is a significant competitive advantage. It requires:

• Appointment of a CBI-authorised AIFM (either a self-managed QIAIF with its own AIFM authorisation, or a third-party AIFM)
• Appointment of a CBI-authorised depositary
• Filing of a complete application pack including constitutional documents, prospectus/supplement, and key service provider agreements
• Confirmation from Irish legal counsel that the documents comply with the AIF Rulebook

AIFMD Compliance and the EU Passport

As an EU-authorised AIF managed by an authorised AIFM, the QIAIF benefits from the full AIFMD marketing passport. This enables distribution to professional investors in all EU/EEA member states via the regulator notification procedure.

The AIFM must comply with the full suite of AIFMD requirements:

• Remuneration policy: Compliance with AIFMD Annex II remuneration principles
• Risk management: Separation of portfolio management and risk management functions
• Leverage reporting: Disclosure of leverage levels using both the gross method and the commitment method
• Liquidity management: Documented liquidity management policies and stress testing
• Annex IV reporting: Periodic regulatory reporting to the CBI, including portfolio composition, leverage, liquidity, and counterparty exposure

Investment and Borrowing Flexibility

The QIAIF has significantly fewer investment restrictions than retail fund vehicles:

• No diversification requirements: Unlike UCITS, a QIAIF may concentrate its portfolio in a single asset or a small number of positions
• Unlimited leverage: There is no regulatory cap on borrowing, though the AIFM must disclose leverage levels and manage liquidity risk appropriately
• All asset classes: The QIAIF may invest in listed and unlisted securities, derivatives, real estate, private credit, digital assets, commodities, and any other asset class
• Side pockets: Permitted with appropriate disclosure in the prospectus

This flexibility makes the QIAIF suitable for hedge fund strategies, private credit, real estate, infrastructure, and multi-asset mandates that cannot fit within the UCITS framework.

Cost Profile

The cost of establishing and maintaining a QIAIF is competitive with other EU jurisdictions:

• Legal structuring: EUR 60,000–EUR 120,000 for a standard QIAIF (ICAV structure) including prospectus, supplement, constitutional documents, and service agreements
• CBI authorisation fee: EUR 3,000 (one-off) plus annual levy
• AIFM fees: EUR 25,000–EUR 65,000 per annum base fee (for third-party AIFM), plus AUM-based charges
• Depositary fees: EUR 15,000–EUR 40,000 per annum base fee, plus transaction and custody charges
• Fund administration: EUR 50,000–EUR 120,000 per annum depending on portfolio complexity
• Audit: EUR 15,000–EUR 35,000 per annum

Total first-year costs for a standard QIAIF are typically EUR 200,000–EUR 400,000, with ongoing annual costs of EUR 150,000–EUR 300,000.

When to Choose an Ireland QIAIF

The QIAIF is the optimal vehicle when:

• The manager targets UK and US institutional investors who prefer an Irish-domiciled fund
• US tax-efficient structuring is required (ICAV check-the-box election)
• The 24-hour fast-track authorisation pathway is available
• The fund strategy requires the AIFMD marketing passport for EU distribution
• The investor base values CBI regulatory oversight as a governance safeguard

Key Takeaways

• The Ireland QIAIF is authorised by the Central Bank of Ireland under the AIFMD framework, with a 24-hour fast-track approval available for funds using pre-approved service providers and standard documentation
• The minimum subscription of EUR 100,000 per investor is a CBI requirement and cannot be waived
• The ICAV structure dominates new QIAIF launches due to its ability to check the box for US tax purposes, making it attractive for US taxable investors without requiring a separate Delaware feeder
• Total first-year costs are typically EUR 200,000–EUR 400,000, competitive with Luxembourg but requiring CBI approval rather than AIFM-only supervision
• The AIFMD marketing passport provides access to professional investors across the entire EU/EEA through a standardised notification procedure
• Ireland is the preferred domicile for managers targeting UK and US institutional capital, while Luxembourg tends to attract Continental European allocators
