The Complete Guide to Setting Up and Managing a Limited Company in Ireland

Ireland is seeing record levels of new incorporations. The Companies Registration Office (CRO) reported that 23,652 new companies were formed in 2024, up 5.7% on 2023. That’s an average of almost 2,000 new companies a month.

Meanwhile, Irish SMEs remain the backbone of the economy, making up 99.8% of all businesses according to the CSO’s Business Demography series. In fact, Q1 2025 saw 6,340 new startups opening their doors, a 3.9% rise on the same period in 2024.

Why So Many Irish Entrepreneurs Are Choosing A Limited Company

Limited liability and separate legal status

A Private Company Limited by Shares (LTD) is a separate legal person in the eyes of the law. That means the company, not you personally, signs contracts, owns assets and is sued if something goes wrong.

For most shareholders, their financial risk is limited to what they have invested in shares. Your personal home and savings are generally better protected than they would be as a sole trader, where you are personally on the hook for business debts.

Potential tax efficiency

Irish limited companies pay 12.5% Corporation Tax on trading profits, with higher rates only applying to certain passive or non-trading income.

This 12.5% percent headline rate still applies to trading profits, even as global minimum tax rules are being rolled out for very large multinationals.

For many growing businesses, leaving some profit in the company at 12.5 percent and paying yourself a mix of salary and dividends can be more efficient than having all profit taxed as personal income, which can reach effective rates over 50 percent.

Credibility and growth potential

A limited company structure can:

Make it easier to raise investment by issuing shares
Improve credibility with larger customers and suppliers
Help you separate your personal finances from the business more clearly

With more than 23,000 new companies set up in 2024 and over 6,300 startups in the first quarter of 2025 alone, there is clear evidence that Irish entrepreneurs see company formation as a serious route to growth.

Core Features Of An Irish Limited Company

When people talk about “going limited” in Ireland, they almost always mean forming a Private Company Limited by Shares (LTD) under Part 2 of the Companies Act 2014.

Here are the key features in 2025.

Directors and company secretary

The CRO confirms that:

Every company must have at least one director
For most company types, two directors are required, but an LTD can have one director if it appoints a separate company secretary
At least one director must be resident in the European Economic Area (EEA)

If you do not have an EEA resident director, you can instead put a Section 137 Bond in place. The bond provides a €25,000 guarantee to the State and typically costs around €1,600 to €2,000 for a two-year period, according to specialist formation providers.

Registered office address

Your company must have a registered office in the Republic of Ireland where CRO and Revenue post can be delivered and where certain records are available for inspection. Virtual office providers are acceptable as long as a physical address is available for document inspection.

Share capital

There is no statutory minimum share capital for an Irish LTD. Many small companies start with a simple structure such as 100 ordinary shares of €1 each.

You will include details of authorised and issued share capital in the company’s constitution and keep a register of shareholders.

Beneficial owners

Separate from shareholders on paper, Irish and EU anti-money laundering rules require you to identify your beneficial owners. New Irish companies must:

Keep an internal register of beneficial owners
File that information with the Register of Beneficial Ownership (RBO) within five months of incorporation

The RBO’s 2024 annual report shows that around 88% of Irish companies had filed their beneficial ownership details by the end of 2024, showing how seriously this is enforced.

Step By Step Company Formation In Ireland

Let us break the process down so you can see what is involved.

Step 1: Decide if a limited company is right for you

Choosing a business structure can feel confusing, so it helps to start with what actually matters to you. Think about how you like to work, what risks you want to protect yourself from and where you see your business going. Factor in:

Your appetite for admin and deadlines
Whether you need limited liability
Your projected profit and personal income needs
How important external investment or credibility is in your sector

We have provided comparisons between sole trader, partnership and limited company to help you decide in our blog on ‘How To Choose The Right Company Structure In Ireland’.

Step 2: Choose a company name

Your name must be unique and not too similar to an existing company. Check the CORE (Companies Online Registration Environment) in advance. Names which are misleading, offensive or suggest State backing will be rejected.

Usually, an Irish LTD name ends in “Limited” or “Ltd”.

Step 3: Decide on directors, secretary and shareholders

Now it is time to sort out who will help run your company. People who will carry the legal and practical responsibilities of the business. Who do you trust to take on the key roles, and how will you want ownership to be distributed? Determine:

Who will act as directors
Who will act as company secretary
How many shares will be issued and to whom

If no director is EEA resident, you should build in time and budget for a Section 137 bond.

Step 4: Prepare the constitution

Under the Companies Act 2014, Irish companies must adopt a constitution that sets out their rules. For LTDs, this replaces the older memorandum and articles of association.

The Irish Statute Book has examples of constitutions. However, businesses prefer to have an accountant or solicitor tailor it to their needs, especially if there will be multiple shareholders.

Step 5: File Form A1 and supporting documents

You register the company with the CRO using Form A1 and uploading your constitution through the online CORE system. The CRO’s fee schedule currently has an electronic A1 filing costing €50, with paper incorporations no longer used for standard LTDs.

Once filed correctly, many companies are incorporated in around five working days, although complex structures can take longer.

Step 6: Receive your CRO documents

When the CRO approves your application, you will receive:

Your Certificate of Incorporation
Your Company Number
The stamped Constitution

From this point on, your company is alive in law. Public filings can be inspected on the CRO register.

Essential Registrations After Incorporation

Getting your CRO number is only the beginning. You also need to set things up with Revenue and other bodies.

Register with Revenue

New companies must:

From 1 January 2025, the VAT registration thresholds have increased to €42,500 for services and €85,000 for goods, which provides more breathing space for smaller traders.

Register beneficial ownership

As noted earlier, you must file your beneficial ownership data with the RBO within five months of incorporation. Failure to do so is an offence and can lead to fines.

You can file online and will need Personal Public Service Numbers (PPSNs) or verified identity forms for the beneficial owners.

Set up banking and internal systems

The best practice is to:

Open a business bank account in the company name
Put basic bookkeeping software in place
Decide how you will store invoices and receipts, ideally in digital format

This is where working with an accountant from day one can keep things simple.

Your Ongoing Compliance Checklist

Once you are up and running, there are a few recurring obligations to keep on your radar.

Annual return to the CRO

Your first Annual Return (Form B1) is due exactly six months after incorporation. No financial statements are filed with this first return.

After that:

An Annual Return is due every 12 months
Financial statements must be filed with the second and all subsequent returns
Late filing leads to automatic late fees and loss of audit exemption for two years

Corporation Tax and other taxes

Revenue sets out that Corporation Tax applies to your company’s profits at:

12.5% for trading income
25% for certain non-trading income

You will need to:

File a CT1 Corporation Tax return usually within nine months of your year-end
Pay preliminary Corporation Tax during the year once you are established
Ensure directors file personal Form 11 returns if they are self-assessed

If you are VAT registered, you will also have regular VAT 3 filings, usually every two months, and PAYE filings if you run payroll.

Keeping proper books and records

Companies are legally required to keep proper books of account, and VAT and tax rules require you to retain records for at least six years.

Good records are not just about staying legal. They also make your year-end accounts, loan applications and funding pitches much easier.

Realistic Costs Of Running A Limited Company

It is worth being honest about the costs so you can budget properly. Basic government and professional costs typically look like this:

CRO incorporation fee
- €50 for online Form A1 filing
Legal or formation support
- Often €500 to €1,500 depending on complexity
Accounting setup and ongoing support
- For a straightforward small company, many firms quote from €1,000 to €2,000 a year for accounts and tax compliance
- More complex or high-volume businesses will naturally pay more
Section 137 bond (if needed)
- Around €1,600 to €2,000 for a two-year bond that provides €25,000 cover

These costs might feel heavy at the start, but they are part of buying peace of mind and avoiding far more expensive penalties later.

Is A Limited Company Right For You Now?

There is no one-size-fits-all answer. Let’s go over some common rules of thumb.

A limited company can be a good fit if:

You expect profits to grow beyond what you need personally
You want to ring-fence risk and protect your personal assets
You plan to bring in investors or business partners
You are tendering for contracts where a company structure is expected

Staying as a sole trader may suit you longer if:

Your profits are modest and you need to take out almost everything you earn
You prefer minimal admin and are relaxed about personal liability
You are testing a side project before committing fully

The nice thing is that you can start as a sole trader and incorporate later. That transition is common in Ireland, but it has tax and legal steps, so it is worth planning with an accountant.

Limited Company FAQs For Irish Business Owners

How long does it take to register a limited company in Ireland?

If your documents are in order, many LTDs are incorporated within five to ten working days once they are submitted through the CRO’s online system. Using an accountant or formation agent often helps avoid name rejections or missing information that can cause delays.

Do I always need an EEA resident director?

In general, yes. Section 137 of the Companies Act 2014 requires at least one EEA resident director.

If you cannot meet that requirement, you will need to arrange a Section 137 bond that provides €25,000 cover and usually lasts two years.

What is the current Corporation Tax rate for Irish companies?

For most Irish trading companies, the Corporation Tax rate on trading income is 12.5%. Non-trading or passive income is generally taxed at 25%.

Large multinationals that fall under OECD Pillar Two rules may face an effective minimum rate of 15 percent, but this does not affect typical Irish SMEs.

When is my first Annual Return due?

Your first CRO Annual Return (Form B1) is due exactly six months after incorporation, and you do not attach accounts to that first filing.

After that, an Annual Return is due every 12 months and must be accompanied by financial statements, unless your company has very specific exemptions.

If you are ready to move from “thinking about it” to actually owning your limited company, you do not have to figure everything out alone.
