The Designated Activity Company (DAC) is a unique legal structure in Ireland, tailored for businesses with activities explicitly defined in their constitution. Introduced under the Companies Act 2014, the DAC offers operational flexibility while limiting shareholder liability, making it an appealing choice for entrepreneurs, startups, and organizations with specific missions. This structure is often favored by financing companies, family businesses, and specialized entities like fund management firms or joint ventures.
In this article, we’ll dive deep into the features of a Designated Activity Company in Ireland, the steps to set one up, and its advantages and drawbacks compared to other legal structures like the Private Limited Company (Ltd) or Public Limited Company (PLC).

What is a Designated Activity Company (DAC) in Ireland?
Definition and Features of a DAC
A Designated Activity Company in Ireland is a limited liability company with activities strictly outlined in its constitution. Unlike a Ltd, which can engage in any lawful activity without restriction, a DAC is confined to the objectives specified in its Objects Clause. This provides greater control over the company’s operations, making it particularly suitable for structured financing entities, joint ventures, and fund management firms.
Common examples of DAC activities include aircraft leasing companies, insurance undertakings, regulated financial services, and special-purpose vehicles (SPVs) used in structured finance or securitization transactions. The DAC structure is particularly beneficial in these sectors due to its clearly defined and limited business activities.
A DAC can be private or listed on a stock exchange, though most in Ireland are private. Shareholder liability is limited to their capital contributions, ensuring asset protection. The company name must include “Designated Activity Company” or the abbreviation “DAC” to reflect its legal status.
A DAC requires at least two directors and a company secretary, making it a more formal structure than a Ltd, which can operate with just one director. It must also hold Annual General Meetings (AGMs) and file financial statements, ensuring a higher level of transparency.
Differences Between a DAC, Ltd, and PLC
The key distinction between a Designated Activity Company in Ireland and a Ltd lies in the Objects Clause. While a Ltd enjoys broad operational freedom, a DAC’s activities are restricted to those predefined in its constitution, offering tighter control—especially valuable in regulated sectors like financial services or investment funds.
Unlike a Public Limited Company (PLC), a DAC isn’t required to raise public funds or list on a stock exchange, though it has the option to do so. This shields it from market pressures while retaining operational flexibility. Compared to a Ltd, a DAC provides a more structured legal framework, ideal for mission-specific businesses, joint ventures, or structured financing entities.
Why Choose a Designated Activity Company in Ireland?
Advantages of a DAC in Ireland
The Designated Activity Company in Ireland is perfectly suited for businesses with defined goals and a need for strict legal oversight. It’s a popular choice for joint ventures, fund management companies, structured financing entities, and mission-driven organizations. Its rigid legal framework ensures the company stays focused on its core activities, which is crucial for investors and financial partners seeking transparency and predictability.
A DAC also attracts institutional investors due to its stringent governance and financial reporting requirements. Like a Ltd, it offers limited liability to shareholders, but its defined Objects Clause adds an extra layer of legal protection. Compared to a PLC, a DAC isn’t subject to the same public financial disclosure obligations, preserving the confidentiality of strategic information. Yet, it retains the flexibility to raise funds by issuing shares or bonds.
Additionally, certain DACs, especially those operating as Special Purpose Vehicles (SPVs), may benefit from specific tax neutrality regimes in Ireland, allowing structured finance entities to minimize tax exposure legally. Such advantages make the DAC especially appealing for financial institutions and international investors structuring complex financial transactions.
Drawbacks and Challenges of Setting Up a DAC
The main downside of a Designated Activity Company in Ireland is its operational restriction tied to the Objects Clause. Any activity outside the predefined objectives is prohibited, and expanding operations requires amending the constitution—a potentially complex and costly process. Administrative obligations are also stricter than for a Ltd. A DAC must hold AGMs and submit detailed financial statements to the Companies Registration Office (CRO), incurring additional accounting and administrative costs. Unlike a Ltd, which can operate with a single director, a DAC requires at least two directors, which may complicate governance and increase management expenses. Lastly, while a DAC can raise funds through share issuance, it faces stricter disclosure rules if it opts for public offerings.
Another administrative obligation for DACs involves the mandatory appointment of an external auditor, irrespective of their size. This ensures compliance with the Companies Act 2014 and reinforces financial transparency but represents additional recurring costs compared to a standard Ltd.

How to Set Up a Designated Activity Company in Ireland?
Legal Requirements for Registration
To establish a Designated Activity Company in Ireland, the business must have at least two shareholders, two directors, and a company secretary. The minimum share capital varies depending on the company’s activities, but it’s advisable to set an appropriate capital level to cover potential liabilities.
The company’s constitution must outline its Objects Clause, shareholder rights, and governance rules, all in compliance with the Companies Act 2014. The name must include “Designated Activity Company” or “DAC” to clearly indicate its legal nature.
For DACs operating in regulated sectors such as insurance, banking, or asset management, additional regulatory authorizations must be secured from relevant Irish authorities, including the Central Bank of Ireland. Compliance requirements in these sectors are stringent, involving regular reporting, capital adequacy requirements, and periodic regulatory reviews.
Registration Process with the Companies Registration Office (CRO)
The process begins by checking name availability on the CRO website. Once the name is reserved, the constitution and Form A1 must be submitted to the Companies Registration Office (CRO). Registration fees are €50 for online applications or €100 by mail.
Upon approval, the CRO issues a Company Number, and the DAC becomes a legal entity ready to operate. The average processing time is 5 to 10 working days.

Conclusion
The Designated Activity Company in Ireland is a flexible yet robust legal structure for businesses with specific objectives. It offers limited liability to shareholders, strict governance, and enhanced transparency, while restricting activities to those outlined in its constitution.
Ideal for joint ventures, fund management firms, and mission-specific organizations, the DAC blends operational flexibility with a rigid legal framework that ensures financial transparency. However, it comes with stricter administrative requirements and higher management costs compared to a Ltd.
