The Irish Collective Asset-management Vehicle (ICAV) is an Irish corporate fund structure designed specifically for investment funds, introduced in 2015 to offer a more flexible and tax-efficient alternative to the traditional Irish public limited company (plc) as a fund vehicle. Unlike a standard corporate entity, the ICAV is governed by dedicated investment fund legislation rather than general company law, making it easier to administer and more suitable for modern fund structures.
The ICAV is the most commonly chosen legal form for new Irish-domiciled alternative investment funds, including QIAIFs, and is widely used for UCITS structures as well.
How it works
The ICAV is established under the Irish Collective Asset-management Vehicles Act 2015, which created a bespoke corporate framework for investment funds. Its key features distinguish it from the Irish plc that was previously the primary corporate fund vehicle:
Check-the-box election: The ICAV can elect to be treated as a partnership or disregarded entity for US tax purposes (the "check-the-box" election). This is significant for US taxable investors, who can elect to treat the ICAV as a tax-transparent vehicle, allowing income and gains to flow through directly for US tax purposes rather than being subject to a second layer of corporate tax. This makes the ICAV attractive for mixed investor bases that include US taxable investors alongside European institutional investors.
Simplified corporate governance: Unlike a plc, the ICAV is not required to hold annual general meetings in the way prescribed by general company law, and its constitutive document (the instrument of incorporation) does not need to include provisions mandated by the Companies Act 2014 that are inappropriate for an investment fund. This reduces the administrative burden of annual compliance for fund administrators.
Umbrella capability: An ICAV can be structured as an umbrella fund with multiple sub-funds, each ringfenced from the others with separate assets and liabilities. Investors in one sub-fund have no claim on the assets of another sub-fund. The ICAV umbrella can hold multiple investment strategies (for example, a private equity sub-fund, a private credit sub-fund, and a real estate sub-fund) under a single CBI-authorised entity.
Migration: The ICAV Act allows existing Irish plc funds to migrate into the ICAV structure without requiring a full restructuring. Similarly, non-Irish fund vehicles can re-domicile into Ireland as an ICAV under certain conditions, which has attracted fund managers seeking to move vehicles into the EU following regulatory changes.
For fund administrators, the ICAV is governed by its instrument of incorporation and prospectus (for authorised funds) or private placement memorandum (for privately placed funds). The administrator maintains the ICAV's register of shareholders or limited partners, processes subscriptions, redemptions, capital calls, and distributions, calculates NAV, and prepares CBI regulatory filings. The ICAV's annual accounts are prepared under IFRS or Irish GAAP and filed with the CBI.
The ICAV is typically used as the legal wrapper for a QIAIF when a corporate (rather than partnership or contractual) structure is required or preferred by the investor base. For fund managers whose LP base prefers a limited partnership structure, the Investment Limited Partnership (ILP) is the alternative Irish form.
Worked example
Aldgate Capital Growth ICAV is an Irish ICAV authorised as a QIAIF, with two sub-funds: the European Growth Equity Sub-Fund (EUR 180 million commitments) and the European Direct Lending Sub-Fund (EUR 240 million commitments).
The ICAV was established under the ICAV Act 2015, with the instrument of incorporation filed with the CBI as part of the QIAIF authorisation process. Each sub-fund has a ringfenced pool of assets and its own class of shares.
US taxable investors in the European Direct Lending Sub-Fund made check-the-box elections to treat the ICAV as a disregarded entity for US tax purposes, allowing them to report interest income from private credit investments directly on their US tax returns without a corporate-level Irish tax charge.
The fund administrator maintains two separate ABORs within the same ICAV structure, issues capital calls from each sub-fund independently, and prepares sub-fund level NAV statements for LPs. Annual audited financial statements are prepared at both the umbrella level and the sub-fund level.
Frequently asked questions
Why do US investors prefer the ICAV over other Irish fund structures? The check-the-box election is the primary reason. It allows a US taxable investor to elect to treat the ICAV as a tax-transparent entity for US tax purposes, so that income and gains flow directly to the investor without a second layer of Irish corporate tax. Not all Irish fund structures support the check-the-box election; the ICAV was specifically designed to be eligible. US investors without this election would otherwise face double taxation on fund income.
What is the difference between an ICAV and an ILP in Ireland? The ICAV is a corporate entity (like a company, but governed by fund-specific legislation). It issues shares or units; investors are shareholders or unitholders. The ILP (Investment Limited Partnership) is a partnership structure: investors are limited partners, and the general partner manages the fund. The ILP closely mirrors the UK LP and Delaware LP structures familiar to international private equity investors. The choice between ICAV and ILP depends on investor preferences, LP familiarity with the structure, and whether the check-the-box election (available for ICAVs) or a pure partnership (available through the ILP) better suits the investor base.
Can an ICAV have a single sub-fund? Yes. An ICAV does not need to be an umbrella structure; it can have a single pool of assets. In practice, managers often choose the umbrella structure even for initial single-strategy launches to preserve flexibility for future sub-fund additions without requiring a new fund vehicle.
How are capital calls processed in an ICAV structured as a QIAIF? Capital calls in an ICAV QIAIF follow the mechanics defined in the instrument of incorporation and any shareholder agreement or subscription agreement. The fund administrator prepares capital call notices based on investment decisions made by the AIFM, distributes notices to shareholders (LPs), processes receipt of capital, and updates share registers and capital accounts. For corporate structures, the capital call mechanism may differ slightly from a limited partnership: shareholders may be issued shares on subscription and called for additional capital through a partly paid share mechanism or through a commitment-and-call structure documented in the subscription agreement.
Is the ICAV required to have a prospectus? For QIAIF structures, the ICAV must have either a prospectus (if marketed using the AIFMD passport or national private placement regimes) or a private placement memorandum. The CBI has published a code of practice for QIAIFs that sets out the minimum content requirements for the ICAV's offering document. Unauthorised or sub-threshold AIFs may use a simpler private placement memorandum without full prospectus requirements.
