This article is for Irish entrepreneurs and business owners who are choosing between a private limited company (LTD) and a Designated Activity Company (DAC) for their new venture or considering converting their existing structure.
If you're confused about which company type gives you more flexibility, what the practical differences are in day-to-day operations, or when a DAC might actually be better than an LTD, this guide covers the key operational differences, regulatory requirements, and specific scenarios where each structure makes sense.
Key Takeaways

What's the Main Difference Between DAC and LTD?
The key difference is activity limitation. A private limited company (LTD) can engage in any lawful business activity without restriction.
A Designated Activity Company (DAC) must specify its permitted activities in the company constitution. This distinction affects everything from operational flexibility to regulatory requirements.
What is a Private Limited Company (LTD)?
A private limited company represents Ireland's most common business structure. LTDs enjoy full capacity to carry on any business or activity under Section 38 of the Companies Act 2014.
This means your company can pivot, expand, or diversify without constitutional amendments.
Key Features of LTDs
Operational Flexibility: You can pursue any lawful business opportunity without restriction.
Single Director Option: Only one director is required, simplifying governance.
No Activity Restrictions: Your constitution doesn't limit what business you can conduct.
Simpler Compliance: Fewer statutory requirements than DACs in most situations.
Maximum 149 Shareholders: Cannot offer shares to the public.
What is a Designated Activity Company (DAC)?
A DAC operates with defined activity limitations specified in its constitution. Section 964 of the Companies Act 2014 established DACs as a distinct company type.
Your DAC's activities are restricted to those stated in its objects clause.
Key Features of DACs
Limited Activities: Only permitted activities specified in the constitution are allowed.
Two Directors Required: DACs must have at least two directors under Section 129.
Objects Clause: Constitution must clearly define permitted business activities.
Can Issue Debentures: DACs can create and issue debentures, which LTDs cannot.
Regulated Sector Preference: Often required or preferred for certain regulated activities.
Why Would You Choose an LTD Over a DAC?
Most Irish businesses choose the LTD structure for good reason, the flexibility to pursue any business opportunity without constitutional changes is invaluable. The benefits include:
- Business Pivot Freedom: Change direction without amending your constitution.
- Simpler Governance: One director can make quick decisions without additional oversight.
- Lower Setup Complexity: Fewer restrictions mean simpler constitutional documents.
- Investor Preference: Most venture capital and angel investors prefer LTD structures.
- Future-Proof: You won't outgrow the structure as your business evolves.
When Should You Choose a DAC Instead?
Specific business situations make DACs more appropriate than LTDs. We have found that activity limitations that seem restrictive can actually provide strategic benefits. The best uses for DACs include:
- Joint Ventures: Clear activity definition prevents scope creep in partnerships.
- Special Purpose Vehicles: Lenders prefer defined activities for borrower entities.
- Regulated Activities: Some financial services require DAC structures.
- Holding Companies: Asset protection through activity limitation.
- Professional Service Firms: Clear scope definition for client relationships.
How Do DACs and LTDs Compare on Key Requirements?
It is imperative to understand the practical differences between the two in order to make make an informed choice.
Director Requirements
LTDs: Minimum one director who must be EEA resident (or purchase Section 137 bond).
DACs: Minimum two directors, same residency requirements apply.
This difference affects governance costs and decision-making speed.
Company Secretary
LTDs: Must have company secretary who cannot be the sole director.
DACs: Must have company secretary, no additional restrictions.
Both structures require proper company secretarial services for compliance.
Share Capital
LTDs: No minimum share capital required under Irish law.
DACs: No minimum share capital required for private DACs.
Both can establish flexible share structures for growth.
Constitutional Flexibility
LTDs: General capacity allows any lawful business activity.
DACs: Limited to activities specified in objects clause.
This represents the most significant operational difference.
What Are the Tax Implications?
Both structures pay identical tax rates in Ireland, the 12.5% corporate tax rate applies to trading income regardless of structure. Both DACs and LTDs pay corporation tax of 12.5% on trading income and 25% on non-trading income. The structure choice doesn't affect your tax obligations.
Both structures have identical VAT and PAYE obligations that apply, both must register when turnover thresholds are exceeded.
How Do Formation Costs Compare?
The setup costs are virtually identical for both structures, the main difference lies in constitutional complexity, not registration fees. Registration fees for LTDs and DACs are €50 for online CRO registration or €100 for postal registration. However, the constitutional drafting may cost more for DACs due to the objects clause complexity. Both structures have ongoing compliance costs, for LTDs they have costs for annual return filing, financial statements and registers maintenance. DACs have the same requirements plus costs for potential additional governance meetings. Professional fees typically run slightly higher for DACs.
Can You Convert Between DAC and LTD?
Yes, conversion is possible through re-registration procedures, Section 1296 allows companies to change structure with proper documentation. For a LTD to DAC conversion you must pass a special resolution approving the change and file Form B44 with the CRO along with an amended constitution. The process typically takes 2-4 weeks once the documentation is complete. For a DAC to LTD conversion a special resolution is required and re-registration with the CRO. You must remove the objects clause and activity limitations from the constitution. In addition, creditor protection provisions may apply depending on the circumstances.
What Do Lenders and Investors Prefer?
Investor and lender preferences vary based on the situation, understanding these preferences helps you to choose the right structure.
Most VCs strongly prefer LTD structures for portfolio companies. The flexibility to pivot business models aligns with startup realities and simpler governance structures allow faster decision-making. Banks often prefer DACs for borrower entities in structured finance. The clear activity definition provides comfort around use of funds and the ability to issue debentures adds security options. Corporate investors may prefer either structure depending on their investment thesis. Joint ventures typically favor DACs for activity clarity.
What About Regulated Industries?
Regulatory requirements sometimes dictate the structure choice, for example, certain financial services and licensed activities require a DAC structure. Payment institutions and e-money institutions often use a DAC structure and investment firms may be required to adopt a DAC structure. We recommend checking the the Central Bank requirements for your specific activity. Solicitor firms, accountancy practices, and similar professions can use either structure, the choice depends on their liability protection and governance preferences.
How Does This Affect Daily Operations?
Structure choice impacts how you run your business day-to-day. The activity restrictions in DACs require attention to be brought to operational scope. This can impact business expansion, decision-making speed and clients perception.
Business Expansion
LTDs: Launch new products or services without constitutional changes.
DACs: Expanding beyond defined activities requires constitutional amendment.
This difference matters most for businesses with uncertain evolution paths.
Decision-Making Speed
LTDs: A single director can make quick operational decisions.
DACs: The two-director requirement may slow certain decisions.
Client Perception
LTDs: The standard LTD structure raises no questions from a client
DACs: The DAC structure may signal specific purpose or regulated status to informed observers.
What's the Verdict for Most Businesses?
For 95% of Irish businesses, LTD is the right choice. From our experience, the operational flexibility outweighs any theoretical benefits of activity limitation.
It is recommended to choose DAC only when specific circumstances require it:
- Joint ventures needing activity clarity
- Special purpose vehicles for structured finance
- Regulated activities requiring DAC structure
- Professional advice recommending this structure
For everything else, LTD provides maximum flexibility with minimum complexity.
