If you are planning to incorporate your business or want to understand the real costs involved in company formation, this guide will help you make informed decision. It includes initial setup costs, post incorporation costs and all ongoing costs.
Key Takeaways
- The basic cost to register a company in Ireland is €50 when filing through the CRO's online system (CORE), which covers company name registration, a basic constitution document, and formation of the company structure - but beware of making errors when doing it yourself that will cost you down the road.
- Additional costs beyond the basic registration fee can include company constitution preparation, a company seal (approximately €50), business name registration (€20), and director identity verification (€150 per non-resident).
- Every Irish company must maintain a registered office address in Ireland, with services available from companies like Open Forest for €199 per year for those without physical premises.
- Irish companies require a company secretary, with Open Forest offering a digital company secretary service for €99 + VAT per year to handle statutory obligations.
- Using a company formation agent like Open Forest can save time and reduce potential errors, though it adds to initial expenses.

What Are the Basic Costs to Register a Company in Ireland?
Well for starters, the basic cost to set up a company can be next to nothing.
We have already written an article setting out the exact step-by-step process to starting your business at no cost for yourself. Ok, so it's not technically free as there is a €50 fee to be paid to the Companies Registration Office (the CRO) - but that bit is unavoidable.
But, you genuinely could set up a company for as little as €50.
The rest of the costs, depend entirely on what additional services you want and need.
Standard CRO Registration Fees for a Limited Company in Ireland
As we mentioned, the standard registration fee for a private limited company in Ireland is only €50 when filing through the CRO's online system. So if you see companies charging a lot more for just a basic registration, they are ripping you off.
This basic company registration in Ireland fee covers
- your company name registration (please try to choose a unique name)
- a really basic company constitution document and
- the formation of the actual company structure itself.
What the €50 fee does not cover:
- the legally required Company Secretary;
- a registered office address (your home address may be made public if you use it as the company's address);
- the legally required corporate registers (register of directors, register of shareholders etc);
- the legally required share certificates that must be given to all shareholders;
- any kind of useful company constitution;
- any legal agreements;
- any ID numbers that are required for team members that do not have an Irish Government-issues ID number (PPSN);
- a bank account; and
- any kind of legal or corporate guidance.
Additional Costs Associated with Registering a Company

Beyond the basic CRO registration fee, several additional expenses may arise when looking to register a company in Ireland:
- Company Constitution Preparation: While the company constitution (previously called the memorandum and articles of association) can be prepared yourself, most entrepreneurs opt for a more robust document that includes different share classes so that you can avoid giving away voting power. Our Future Proof package covers this.
- Company Seal: Every Irish company is legally required to have a company seal for official documents, costing approximately €50. In reality, you wont need seal unless your company is signing certain legal documents, called deeds. So, does the law say you have to have one? Yes. Will anyone check if you don't get one immediately? No.
- Business Name Registration: If you plan to trade under a different name than your registered company name, you'll need to register a business name at an additional cost of €20.
- Company Officer Identity Verification: For anyone that will be appointed as a director of your new company (and for anyone that will have over 25% of the shares), you need to have an ID number. Irish residents get issued with what's called a PPS Number through the government. For non-residents, there is a simple way to get an alternative number called an IPN. It costs €150 per person and we will do the application for you.
- Physical Address in Ireland: Your company must maintain a registered office address within Ireland where official communications can be received. For companies without physical premises, Open Forest offers a registered office solution for €199 per year, which is 3x cheaper than the rest of the market too.
- Company Secretary: See our section below on the Company Secretary requirements.
Company Formation Agents
Most entrepreneurs opt to use company formation agents like Open Forest to streamline their registration process and keeping up with compliance obligations after incorporation.
We offer professional services to handle the entire company registration process in Ireland, ensuring compliance with Irish business regulations and minimising delays.
The CRO has a habit of sending documents back if there are any errors in them.
Cost-Benefit Analysis of Using Company Registration Services
When deciding whether to use a company formation agent, consider these factors:
For most businesses, particularly those unfamiliar with the Irish company registration process or those with limited time, it's an absolute no-brainer. Open Forest ensures smooth registration and compliance with Irish company law requirements and ensures that the company is set up as quickly as possible - without and structural errors which will inevitably come back to haunt you.
The cost can skyrocket really quickly if certain errors are made that need a lawyer to fix.
What Are the Ongoing Compliance Costs After Registration?
Understanding the costs involved in registering your business extends beyond the initial setup.
Irish companies face some fairly light recurring compliance obligations that carry their own expenses.
Annual Return Filing Costs with the CRO
Every Irish company must file an annual return (Form B1) with the CRO. "Annual Return" just means making a return (filing a form), annually.
The first annual return is due six months after incorporation and requires no financial statements to be filed with it. This filing is basically just a quick checkin with the CRO to tell them that you are still going.
However, all subsequent annual returns require financial statements to be filed with them. The CRO filing fee for the annual return is always €20 when filed online through the CORE system, but the cost of the financial statements can add up - especially if you use a high-street accountant.
If you use Open Forest to set up your company, we will track your annual return date, let you know when the filing window opens and offer to do the filing for you. We also work closely with our partner account who does a really competitive deal for Open Forest companies.
Late filing of annual returns carries really substantial penalties:
- Late filing fees that increase based on the delay period starting from €100 the day after you are late and increasing each day until it hits €1,200
- Loss of audit exemption (which is the really nasty part) for the following two years - new companies are automatically exempt from having to hire an auditor to check their financial statements. File the annual return late and you lose this exemption for 2 years - this is a really really expensive mistake
- Potential company strike-off if returns remain un-filed
Compliance with Irish Company Law Requirements
Beyond annual returns, Irish companies need to keep on top of various other legal requirements:
- Financial Statements Preparation: Companies have to prepare and file annual financial statements in accordance with appropriate accounting standards. While some small companies can prepare abridged accounts, professional accounting services for this typically cost up to €1,500 annually. We have a partner account that can offer you a lot of savings on this.
- Register of Beneficial Owners (RBO) Filing: Companies must register with the RBO within five months of incorporation. We will remind you about this when it's due and also offer to file it for you for only €50 + VAT. We are 3x cheaper than the rest of the market.
- Tax Compliance: Companies must register for and comply with various tax obligations, including corporation tax, employer taxes, and VAT where applicable. While registration itself is free, professional tax compliance services cost approximately €500-€2,000 annually depending on company size and complexity. Again, our accountant can do all of this at a really low rate - much lower than the market standard. See more below.
Role of a Company Secretary and Associated Costs
Irish company law requires all companies to have a company secretary. The company secretary maintains company records, files annual returns, and ensures compliance with legal obligations outlined in the company constitution. For companies with two or more directors, one director can also serve as company secretary at no additional cost.
Open Forest offers the first digital company secretary service in Ireland (yes there are humans behind it). Our fee is, as usual, the lowest on the market - at only €99 + VAT per year.
We will ensure proper maintenance of statutory registers, timely filing of returns, and proper documentation of company decisions in accordance with the company's constitution and Irish company law.
What's the Step-by-Step Guide to Set Up a Company in Ireland?

Establishing your business in Ireland follows a structured process. Understanding each step helps ensure smooth registration and compliance with Irish business regulations.
Choosing and Registering a Name for Your Company
The first step in the registration process is selecting a unique company name that complies with CRO guidelines. Your company name:
- Will likely end with "Limited"
- Cannot be identical or too similar to an existing company
- Must not be offensive or imply state sponsorship without authorisation
Before submitting your application, use the CRO's free search facility to check name availability. We have written a name guide here that will help you avoid having your application rejected.
Preparing the Company Constitution
The company constitution (formerly known as the memorandum and articles of association) outlines your company's rules and structure. For a private limited company in Ireland, this is a single document that includes:
- Company name
- Statement that liability of members is limited
- Share capital details
- Rights and obligations of shareholders
- Powers and duties of directors
- Procedures for meetings and decision-making
While the CRO doesn't provide constitution templates, Open Forest can provide this for you to suit your business needs.
Setting Up a Business Bank Account for Your New Company

After obtaining your Certificate of Incorporation, it's usually time to set up your business bank account.
Most Irish banks charge monthly fees ranging from €20-€50 for business accounts. While not legally mandatory, a separate business account simplifies accounting, tax compliance, and demonstrates professionalism to clients and suppliers.
We tend to recommend Revolut and we have a contact that we can put you in touch with, so that you will have a point of contact there.
Corporation Tax Registration Expenses
Following incorporation, your company must register for tax with the Revenue Commissioners to satisfy Irish tax laws. While registration itself is free through the Revenue Online Service (ROS), ensure you understand these compliance and tax-related considerations:
- Companies must register for corporation tax within 30 days of commencing business activities
- VAT registration is required if turnover exceeds specified thresholds
- Employer registration is necessary if hiring staff
