This article is for Irish entrepreneurs and business owners who need to choose between an LTD and DAC company structure but aren't sure which one fits their needs.If you're wondering what the actual differences are, which structure makes sense for your business, or whether you're overthinking this decision, this guide covers the key distinctions, compliance requirements, and a simple decision framework to help you choose.
## Key Takeaways- Choose an LTD for most businesses—it's simpler, allows one director, and lets you pivot without constitutional amendments.- DACs require restricted objects clauses that limit activities and need special resolutions plus CRO filings to change business direction.- Financial services, regulated entities, and foreign subsidiaries typically need DACs; standard commercial businesses should use LTDs.- DACs must have two directors minimum and follow more prescriptive governance rules, creating ongoing administrative burden and costs.- You can convert between LTD and DAC later if needed, so start simple rather than choosing complexity unnecessarily.

The Simple Answer
For most businesses, choose a private company limited by shares (LTD).
Unless you have a specific reason to use a DAC structure - and most businesses don't - an LTD is simpler, more flexible, and has fewer compliance obligations.
The rest of this article explains why, what the actual differences are, and the rare situations where a DAC makes sense.
What is a Private Company Limited by Shares (LTD)?
An LTD is Ireland's most common company structure and the default choice for most businesses.
Key features:
- Limited liability for shareholders
- Shares owned by private individuals or other companies (not publicly traded)
- Flexible objects - can engage in any lawful activity
- Simplified compliance requirements
- Single-director capability
- No minimum share capital requirement
When the Companies Act 2014 was introduced, it made the LTD structure deliberately simple and flexible. The law assumes this is what most businesses need, so the default rules are designed to minimize administrative burden.
If you're starting a tech company, consultancy, e-commerce business, marketing agency, or any standard commercial operation, this is your structure.
What is a Designated Activity Company (DAC)?
A DAC is the successor to the old "private limited company" structure that existed before the Companies Act 2014.
The crucial difference: a DAC has restricted objects. Its constitution must specify what activities the company can engage in, and the company cannot operate outside those stated objects.
Key features:
- Limited liability for shareholders
- Objects clause restricting company activities
- More complex constitutional documents
- Additional compliance obligations
- Minimum of two directors required
- More prescriptive governance rules
DACs are designed for situations where you need or want tighter control over what the company can legally do. This matters for regulated businesses, certain types of subsidiaries, and financial institutions.
The Critical Difference: Objects Clause
This is what really separates DAC from LTD.
LTD approach: An LTD has full capacity to engage in any lawful activity. There's no objects clause restricting what it can do. If tomorrow you decide to pivot from software development to selling furniture, you don't need to change your constitution or file anything with the CRO. You just do it.
DAC approach: A DAC's constitution includes an objects clause that lists what the company can do. For example: "to carry on the business of software development and related services."
If you want to do something outside those stated objects, you need to:
- Pass a special resolution (75% shareholder approval)
- Amend your constitution
- File the changes with the CRO
- Wait for approval
This restriction exists for protection - it prevents directors from taking the company in directions shareholders didn't authorize. For most businesses, this "protection" is actually a limitation you don't want.
Compliance: Where DACs Get More Complex
DACs face additional compliance obligations that don't apply to LTDs.
Constitutional documents:
- DAC requires both a memorandum and articles of association (two documents)
- LTD uses a single constitution document
Directors:
- DAC must have at least two directors
- LTD can have just one director
Changes and amendments:
- DAC amendments often require special resolutions and CRO filing
- LTD has more flexibility for internal changes
Corporate governance:
- DACs follow more prescriptive rules around meetings, resolutions, and decision-making
- LTDs have simplified procedures
These differences might seem minor, but they add up. Every special resolution costs time and money. Every mandatory meeting creates administrative work. Every constitutional amendment requires legal review and CRO filing.
For a business focused on growth and flexibility, these extra requirements create friction without adding value.
When Should You Choose a DAC?
There are legitimate reasons to use a DAC structure, but they're specific situations.
Financial services and regulated entities: Banks, credit unions, insurance companies, and other financial institutions typically must be DACs. Regulators prefer the restricted objects approach because it provides clearer boundaries around what these entities can do.
Subsidiaries of foreign companies: Some multinational companies prefer their Irish subsidiaries to be DACs because:
- It mirrors structures in other jurisdictions
- The restricted objects provide control over subsidiary activities
- Group policies may require DAC structures
Joint ventures: When multiple parties create a company for a specific purpose, a DAC with restricted objects can provide assurance that the company won't stray from its intended purpose.
Specific contractual requirements: Occasionally, contracts or investment agreements require DAC structures. For example, some investors or partners may specify DAC as a condition.
Holding companies with specific purposes: If you're creating a holding company for a defined purpose (like owning shares in specific subsidiaries), a DAC can provide structural clarity.
When you genuinely want restricted objects: Rarely, founders prefer the discipline of stated objects to prevent scope creep or unauthorized activities.
Notice what's not on this list: "wanting to look more professional" or "thinking DAC sounds more legitimate." These are bad reasons to choose a more complex structure.
When Should You Choose an LTD?
For almost everything else.
Standard commercial businesses: Tech companies, consultancies, e-commerce stores, marketing agencies, professional services, retail, hospitality, manufacturing - virtually any normal business operation.
Startups expecting to pivot: If you're not certain exactly what your business will do long-term, you need the flexibility an LTD provides. Many startups evolve significantly from their original concept.
Businesses wanting operational flexibility: If you want to adapt quickly to opportunities without constitutional amendments and shareholder approvals, choose LTD.
Single-founder companies: If you're the only director and don't want to appoint a second one, LTD is your only option.
When simplicity matters: If you want to minimize administrative burden and focus on building your business rather than managing corporate governance, LTD is the clear choice.
Cost Differences
The structural differences create cost differences both at incorporation and ongoing.
Incorporation costs:
- Both cost the same in CRO fees (€50)
- DAC may have higher legal costs due to more complex documentation
- Through Open Forest, both start at €99
Ongoing costs:
- DAC amendments require special resolutions and CRO filings (€50+ each time)
- DAC may have higher accounting/legal fees due to compliance complexity
- LTD has lower administrative costs overall
The ongoing cost difference isn't huge, but over 5-10 years, the extra compliance work for a DAC can add up to thousands in unnecessary fees.
Can You Convert Between Structures?
Yes, through a process called re-registration.
LTD to DAC: You can convert your LTD to a DAC if circumstances change. This requires:
- Special resolution by shareholders
- New constitutional documents
- Filing with the CRO
- Court approval in some cases
This typically costs €500-1,500 in legal and filing fees.
DAC to LTD: You can also convert a DAC to an LTD, following a similar process. Many companies that started as "old style" private limited companies (before 2014) have converted to the simpler LTD structure.
The key point: you can always convert later if needed. This means there's no reason to choose the more complex structure "just in case" - start simple and convert only if circumstances require it.
Common Misconceptions
"DAC sounds more professional" It doesn't. Most investors, clients, and partners don't care about your company structure - they care about what you do and how well you do it. Choosing unnecessary complexity doesn't impress anyone.
"DAC provides more protection" Both structures provide the same limited liability protection to shareholders. The DAC's restricted objects provide control, not protection. For most businesses, that control is a limitation, not a benefit.
"I need a DAC to look legitimate to investors" Investors care about your business model, traction, and team - not whether you're a DAC or LTD. In fact, many investors prefer the flexibility of an LTD structure.
"DAC is better for larger companies" Company size doesn't determine structure choice. Plenty of large, successful Irish companies operate as LTDs. Structure should match your operational needs, not your ambitions.
The Decision Framework
Ask yourself these questions:
Am I in a regulated industry? If yes (financial services, insurance, etc.), you might need a DAC. Check with your regulator.
Do I need restricted objects for a specific reason? If yes (investor requirement, group policy, joint venture protection), consider DAC. Otherwise, no.
Will I benefit from the extra governance structure? For most businesses, the answer is no. The extra structure creates work without adding value.
Do I want maximum flexibility? If yes, choose LTD. You can always convert later if circumstances change.
If you answered no to the first three questions and yes to the fourth, choose LTD.
