What’s the Cheapest Way to Register a Limited Company in Ireland?

If you are setting up a limited company in Ireland, one of the first questions is usually about cost. That is a fair question. But “cheapest” and “best value” are not always the same thing, and the gap between them is where a lot of founders get caught out.

Here is our honest answer: what the cheapest route actually costs, where the hidden costs appear, and when saving money at setup ends up costing more later.

The genuinely cheapest route: do it yourself through the CRO

The cheapest way to register a limited company in Ireland is to form it yourself through CORE, the Companies Registration Office online portal.

At the most basic level:

• The CRO online incorporation fee is currently €50.
• Reserving a company name in advance costs €25, though that fee can be offset against the incorporation fee if you incorporate within the reservation period.

So on paper, forming a company in Ireland is very low cost.

But that figure only gets you incorporated. It does not include advice on the right company structure, shareholding, company secretary, registered office, RBO filing, tax registration, VAT registration, bookkeeping setup, or ongoing compliance.

Our honest view: DIY is cheap only if the company is very simple and you understand exactly what you are doing. The low CRO fee gives the impression that setting up a company is just an admin form. It is not. The form is cheap. Mistakes are expensive.

Where the hidden costs appear

The hidden costs usually show up after the company is formed. Common follow-on costs include:

• Registered office address
• Company secretary support
• RBO filing support
• Revenue tax registration
• VAT registration
• PAYE registration
• Bookkeeping software and setup
• Annual return filing
• Year-end accounts
• Corporation tax return
• Correcting filings that were done wrong
• Late filing penalties

The biggest hidden cost is usually clean-up work. A founder saves money on the formation, then later discovers the company has the wrong share structure, no proper RBO filing, a missed Revenue registration, no bookkeeping system, or a CRO deadline they did not know about.

Two examples we see often

The first is a founder who used a cheap online formation service and got the company number quickly. On paper the company existed, but nothing else had been thought through. There was no proper guidance on RBO, no tax registration plan, no VAT review, no bookkeeping system, and no explanation of the first annual return. By the time they came to us, they did not need basic formation anymore. They needed post-formation clean-up.

The second is a non-resident founder who assumed formation would cost the same as it does for an Irish-resident founder. They had no EEA-resident director and had not budgeted for the Section 137 bond. The “cheap” formation suddenly became more expensive and slower, because the non-resident director issue had not been dealt with at the start.

The lesson is simple: cheap is only cheap if the setup is correct.

Non-resident founders: “cheap” means something different

For non-resident founders, the cheapest route can change completely.

If the company has no EEA-resident director, it may need a Section 137 non-resident director bond. The statutory bond value is €25,000, but you normally pay a bond premium to a provider, usually covering a two-year period. In practice, non-resident founders should commonly budget around €1,800 to €2,500 for the bond premium, depending on the provider.

Non-resident founders often also need support with:

• An Irish registered office address
• Company secretary
• Certified ID and proof of address
• RBO filing
• Identity verification, such as Form VIF, where there is no Irish PPS number
• Bank account onboarding
• Revenue registration
• VAT registration evidence
• Irish tax and substance advice

So for a non-resident founder, the cheapest route is rarely just the CRO fee. The real cost depends on director residency, banking, RBO, tax registration, and whether the company has a genuine Irish business purpose.

The most common expensive mistakes

When founders optimise only for the lowest setup price, we tend to see the same mistakes:

• Choosing the wrong company type
• A poor share structure
• No thought given to future investors or shareholders
• Using a home address without understanding the public register implications
• No proper registered office arrangement
• Company secretary not properly considered
• RBO filing forgotten or delayed
• VAT registration applied for too early or too late
• No PAYE registration when directors or staff are being paid
• No bookkeeping system from day one
• The non-resident director bond requirement missed
• Assuming the company is ready to trade the moment it is incorporated

Every one of these is avoidable when the setup is planned properly from the start.

Registered office address: free vs paid

Your registered office appears on the public record, and official CRO correspondence goes there. That matters for this decision.

The cheapest option is to use an address you already have, such as a home or business address in Ireland. That can be fine for some Irish-resident founders, as long as you are comfortable with it appearing on the public register.

Paid options include a registered office service, an accountant’s office address, a serviced office, or a formation provider’s address. These give a more professional setup and reduce the risk of important post being missed.

Our practical recommendation:

• If you have a suitable Irish business address and are comfortable using it publicly, that can keep costs low.
• If you are non-resident, working from home, moving address often, or worried about missing CRO or Revenue correspondence, use a paid registered office service.

The cheapest address is not always the safest address.

The ongoing costs founders forget

Founders think about the cost of incorporation but forget the cost of running the company properly. Ongoing costs can include:

• Annual return filing
• Year-end financial statements
• Corporation tax return
• Bookkeeping
• VAT returns if registered
• Payroll if directors or employees are paid
• Company secretarial updates
• Registered office renewal
• RBO updates where ownership changes
• Software subscriptions
• Professional advice for tax or structure changes

Even a dormant or non-trading company has compliance obligations. A company is not something you form once and forget.

The first annual return matters especially. Missing CRO deadlines can lead to late filing fees and the loss of audit exemption, which can be far more costly than paying for proper compliance support in the first place.

What a bare-bones formation leaves out

A bare-bones formation gives you the incorporation and the certificate. That may be enough if you know exactly what you are doing.

But it usually leaves out the practical setup around the company. When we form a company, we look beyond the CRO filing at:

• Company structure
• Director and secretary requirements
• Shareholder setup
• Registered office
• RBO requirements
• Revenue registration
• VAT and PAYE position
• Non-resident director issues
• Bank account readiness
• Bookkeeping setup
• The annual compliance timeline
• Ongoing accounts and tax filing

The difference is that we are not only trying to get the company formed. We are trying to make sure it is usable, compliant, and set up properly for your actual business.

So what is the cheapest way, honestly?

If you asked us directly, our honest answer is this: the cheapest way is to do it yourself through the CRO. But the cheapest safe way is to understand what you are forming before you press submit.

If you are an Irish-resident founder setting up a very simple company, with no unusual shareholding, no non-resident issue, no immediate VAT complexity, and you are comfortable handling CRO, RBO, Revenue and annual returns yourself, DIY may be fine.

But if you are non-resident, have more than one shareholder, expect investment, need VAT, will run payroll, need a bank account quickly, or are unsure about the structure, the cheapest route can quietly become the most expensive one later.

Our view is simple: save money where it makes sense, but do not save money on the part that decides the company’s legal, tax, and compliance foundation.

For context, DIY registration through the CRO starts with a low statutory filing fee, but that only covers incorporation. Professional formation support with OTHS is quoted from a fixed starting price depending on complexity, with additional costs where you need a registered office, company secretary, RBO support, Revenue registration, VAT registration, payroll setup, a non-resident director bond, or ongoing accounting. OTHS company formation support starts from €300 plus VAT, depending on the structure and level of support required.

On timing: a simple Irish-resident company can usually be formed within a minimum of five working days once documents are ready. A fully operational company, with tax registration, bank account, RBO and VAT where required, takes longer. Non-resident cases should be treated as a more detailed setup, not a basic formation.
