How to Register a Company in Ireland: Steps, Costs and Pitfalls

To register a company in Ireland, you file Form A1 and a constitution with the Companies Registration Office (CRO), usually through its online CORE system. The official electronic fee is €50. That gets you a company. It does not get you a tax number, a payroll set-up, a VAT registration or a compliant first year. Those come afterwards, and that is where most new owners lose time.

This guide walks through the whole sequence in order: choosing the structure, the CRO filing, the director rules, Revenue registration, beneficial ownership and the first annual return. It also covers what it costs and when it makes sense to hand the work to an accountant.

TL;DR

Registering an Irish private company (LTD) costs €50 in CRO fees when filed electronically. Professional fees, accounting and tax registrations are separate.
The CRO's electronic scheme targets 10 working days for correctly completed submissions. Errors in names, addresses or officer details cause rejections and delay.
Non-EEA founders must solve the EEA-director question (residence, a €25,000 bond or an economic-link certificate) before filing, not after.
Once you have a CRO number, you register with Revenue for corporation tax, and where relevant PAYE, VAT and RCT.
Every company must file an annual return, even if it never trades.

Decide first: company or sole trader?

A company is not automatically the better choice. Citizens Information explains that a sole trader is simpler and avoids the incorporation fee, but the owner stays personally liable for business debts. A limited company is a separate legal entity with limited liability for shareholders, but it brings CRO, Revenue, accounting and annual-return obligations that a sole trader does not have in the same form.

A few practical pointers:

Low-risk, low-turnover work, a freelancer testing the market: sole trader is often the cheaper and lighter start. If you trade under a name other than your own, you must register a business name.
Contractors, startups, anyone taking on contracts, staff or investors: a company usually makes more sense, because it separates your personal assets from the business and gives you a structure to grow into.
Anyone unsure: make the decision with the numbers in front of you. Structure affects tax, liability, payroll and VAT, so it is worth an hour with an accountant before you file anything.

The usual choice for a small trading business is the LTD, a private company limited by shares. The CRO also recognises other forms, including the DAC, CLG, PLC and unlimited company, but these suit specific purposes such as charities, guarantee structures or public listings. If you are reading this to start a normal trading business, you almost certainly want an LTD.

What you need before you file

The CRO application can only be completed when you have the following ready. Gathering it first is the single best way to avoid a rejection.

A company name. Check it against the register on CORE so it is not the same as or too close to an existing name.
A registered office address in Ireland. This is where official post goes and where the company's records are kept.
Directors and a secretary, with their details and signed consents to act.
Subscribers and share details: who holds how many shares at incorporation.
A constitution, which sets out the company's rules.
Identification, since the CRO's service targets depend on complete, correct submissions and identification checks.

The CRO's own required steps page is the authoritative list of what the application must contain.

Directors: who can act, and the EEA rule

The Companies Act 2014 generally lets one or more persons form a private company. An LTD can have a single director, whereas other company types generally need two. A director cannot be under 18, according to the CRO's directors leaflet.

The residency requirement

Most companies need at least one director resident in the European Economic Area. If none of your directors is, the CRO leaflet describes two routes:

put in place a €25,000 bond under section 137; or
obtain a section 140 certificate, showing a real and continuous link between the company and economic activity in Ireland.

Both routes are set out in the CRO's directors leaflet. They are structuring decisions, not paperwork. If you are based outside the EEA, resolving this before incorporation matters because a change of structure later can hold up banking, tax registration and contracting.

Separately, incorporating a company is not the same as having permission to live and work here. The Citizens Information guide notes that non-EU, non-EEA, non-UK and non-Swiss nationals need permission to come to Ireland to operate a business. EEA and Swiss nationals do not, as the Irish Point of Single Contact explains.

Filing with the CRO, step by step

Choose and check the name on CORE.
Prepare the A1 form and constitution with all officer, address and share details.
Submit electronically through CORE and pay the €50 A1 fee.
Wait for the CRO's checks. The electronic incorporation scheme aims to issue a certificate within 10 working days for correctly completed documents. The ordinary online route is described by the CRO as taking up to 15 working days.
Receive the certificate of incorporation and your CRO number. You need the number for everything that follows.

The timeline is conditional. A cheap self-filed application is not necessarily the fastest if the name, constitution or addresses trigger a rejection and a resubmission. That is the main practical argument for having someone experienced prepare the filing.

What does it cost?

The official figures are small. The professional layer on top depends on how much you want handled.

Item	Cost	Source
New company application (A1), electronic	€50	CRO fees
Annual return (B1), electronic	€20	CRO fees
Company name change, electronic	€50	CRO fees

These are CRO filing fees only. They exclude registered-office services, company secretary, accounting, payroll, VAT or tax-agent costs. Anyone quoting you a total should show you each of those lines separately.

If you want the formation handled alongside your accounts, our company setup service covers Irish-resident founders, EU and EEA-resident founders, and non-EEA founders. Formation is quoted according to the complexity of the structure rather than from a fixed list price.

After incorporation: registering with Revenue

This is the step that turns a registered company into one that can trade properly. Revenue states that you must have a CRO number before you can register for tax as a new company. Registration is made through ROS by a tax agent, or through the TR2 route if you are not represented. TR2 can cover corporation tax, employer PAYE, VAT and Relevant Contracts Tax (RCT), and Revenue then issues a tax reference number.

Which taxes you register for depends on what the company does and whom it pays:

Corporation tax: applies to the company's profits. It is the baseline registration.
Employer PAYE: needed if you will pay yourself a salary as a director or employ anyone. Our payroll service is priced at €25 per month per employee or director.
VAT: needed once your turnover or the nature of your sales requires it, and sometimes worth doing voluntarily. See our VAT return services.
RCT: relevant for companies working in construction, forestry or meat processing contract relationships.

Every company that is incorporated or begins trading must also give Revenue a Statement of Particulars, which is due within 30 days after trading begins. It is a separate action from the tax registration itself and is easy to forget.

Beneficial ownership and the first annual return

Ireland has two registers that new company owners confuse: the CRO register of companies and the Register of Beneficial Ownership (RBO). Incorporation does not file your RBO details for you. Plan the RBO filing as its own task. Our RBO registration is a 119 € one-off.

Then there is the annual return. Every company, including a non-trading one, must file it. The CRO says it is due within 56 days of the annual return date, with financial statements generally attached unless an exemption applies. Late filing can add €120 plus €3 per day, capped at €1,200 per return, and can affect audit exemption. The electronic B1 fee is only €20, so the penalty for missing it is out of all proportion to the cost of filing on time. Our guide to the B1 annual return covers the deadlines and accounts in more detail, and our annual compliance service handles the filing.

Changing a company name later

If you want to rename an existing company, the process is a CRO filing too, and the electronic fee is €50. The new name must be available on the register, and the company's records, bank details, invoices and Revenue details should be updated afterwards. Choosing a name you can live with at the start saves you this administrative round trip.

Our perspective: formation is the start of compliance, not the finish

We see the same pattern with new Irish companies. The founder files with the CRO, gets the certificate, and assumes the hard part is over. Then the tax registrations, the payroll set-up, the first VAT period, the RBO filing and the first annual return arrive as separate problems, usually in the wrong order and sometimes with penalties attached.

That is why we do not treat company formation as an isolated task. Our approach connects bookkeeping, payroll, VAT, management accounts and annual compliance from the first day, so that the CRO filing, the Revenue registration and the first set of books are planned as one sequence. Our team is ACCA-qualified and works on cloud platforms such as Xero, QuickBooks and Sage, so your records are in the right place from the first invoice.

Our honest advice for different founders:

Contractors: do not incorporate only because a company looks more professional. Compare your likely take-home pay as a sole trader and as a director first. Our take-home pay calculator is a quick starting point, and our page for contractors and freelancers explains how we support them.
Startups and e-commerce owners: settle shareholders, share allocation and VAT early. These are expensive to unpick later.
Non-EEA founders: decide the director, bond or economic-link route before anything is filed.

If you want the company registered and the books, payroll and tax registrations set up in the same engagement, start with our company setup service. For ongoing support, our monthly packages for limited companies start from €159 per month for LTD Essential, €239 per month for LTD Growth and €419 per month for LTD Scale. E-commerce packages carry the same starting prices, and sole trader packages start from €129 per month. VAT registration and PAYE registration are 119 € each, one-off. See the full list on our pricing page.

Pitfalls we see most often

A name rejected late. Check availability on CORE before you print business cards or build a website.
Inconsistent addresses and officer details across the form, the constitution and the supporting documents.
No plan for the EEA-director rule, discovered only when the application stalls.
Starting to trade before tax registration is done, which creates invoicing and VAT problems from the first sale.
No calendar for the first annual return, because the company has "not traded yet".
Backlogs of bookkeeping. If records pile up in the first months, catching up costs more than keeping up. We offer catch-up bookkeeping from €35 per hour.

The Local Enterprise Office also provides Start Your Own Business support, as Citizens Information notes, which is useful at the idea-testing and business-plan stage, before you decide on a structure.

FAQ

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

The CRO's electronic incorporation scheme targets 10 working days for correctly completed submissions, and describes ordinary electronic processing as up to 15 working days. The clock depends on the submission passing checks, so errors add time. Revenue registration follows once you have the CRO number.

What is the cheapest way to start a business in Ireland?

Operating as a sole trader avoids the CRO company-incorporation fee and is simpler to run. The trade-off is that you are personally exposed to business debts. If you trade under a name that is not your own, you also need to register a business name.

Can a non-resident register a company in Ireland?

Yes, but the company generally needs an EEA-resident director, unless it has a €25,000 bond in place or a section 140 economic-link certificate, according to the CRO. Non-EEA nationals also need permission to come to Ireland to run a business. Settle both questions before you file.

Do I need to file anything if my new company is not trading?

Yes. Every company, including a non-trading one, must file an annual return, and late filing carries penalties. Financial statements are generally attached unless an exemption applies.

Do I need an accountant to register a company?

Not legally for the CRO filing, but a tax agent can register you with Revenue through ROS and coordinate the sequence after incorporation. An accountant adds the most value when your structure involves directors abroad, payroll, VAT or several shareholders.
