Search “what documents do I need to form an Irish limited company” and you will find checklists. Most of them stop at the Companies Registration Office (CRO) form. That is the easy part. The real question founders are asking, especially when they are not living in Ireland, is broader: what do I need to prepare so the company is not just incorporated, but actually able to trade?
We form companies for clients every month, Irish-resident and non-resident. Here is what the document list actually looks like, where it trips people up, and what a real case taught us about the gap between “incorporated” and “ready to trade”.
The core documents for a standard Irish limited company
For a straightforward Irish LTD, we normally work through:
- Company name options
- Business activity description
- Registered office address in Ireland
- Director details
- Company secretary details
- Shareholder details
- Share allocation and share structure
- Form A1 information for the CRO
- Company constitution
- ID for directors and shareholders
- Proof of address for directors and shareholders
- PPS number, where the person has one
- Beneficial ownership details for the RBO
- The Verification Instrument Form (VIF) route, where a beneficial owner has no Irish PPS number
- Tax registration details, where Revenue registration is required
- VAT registration details, where VAT applies
- PAYE registration details, where directors or employees will be paid
- Bank account documentation, where banking support is needed
The CRO filing creates the company. RBO, tax registration, bank account opening and getting the accounting set up are separate steps that come after. A lot of the confusion around this question comes from treating those as one event instead of a sequence.
The document that causes the most delays
In our experience, proof of identity and proof of address cause more delays than anything else, particularly for non-resident clients. Names need to match properly across the passport, proof of address, shareholder details, RBO filing and bank documents. A small spelling difference, a middle name used on one document and dropped on another, an old address, or a translated document, and the process stalls.
The second recurring issue is the RBO filing itself. Clients often assume that once the company is formed, the setup is complete. It is not: beneficial ownership is a separate filing that comes after incorporation, and it is easy to miss if nobody flags it.
Registered office and RBO: the part people skip past
The registered office has to be an address in Ireland. It is the official address for CRO and legal correspondence, and documents sent there can be treated as delivered even if the client never sees them, so it is not something to treat casually. Irish-resident founders can sometimes use a home or business address, but it is worth remembering that address becomes part of the public record. Non-resident founders usually need a registered office service instead.
RBO is not the same filing as CRO incorporation. If the beneficial owner has an Irish PPS number, that helps with identity verification. If they do not, the VIF route usually applies. Company formation is not finished until these post-incorporation filings are handled, not just the CRO certificate.
What changes if you are forming the company from outside Ireland
For non-resident founders, the document list is usually longer:
- Certified passport or national ID
- Proof of overseas residential address
- Details of tax residency
- Source of funds information for banking
- A Section 137 bond, where there is no EEA-resident director
- Details of any EEA-resident director being appointed instead
- The VIF route, where a beneficial owner has no Irish PPS number
- A more detailed explanation of the business activity
- Evidence of Irish or EU commercial purpose
- Contracts, a website or customer details, where these are needed for VAT registration
- Additional bank due diligence documents
The biggest difference is not the paperwork volume. It is that a non-resident founder has to deal with director residency, identity verification and banking checks in more detail, and sometimes Revenue questions as well. A non-resident can set up an Irish company. The documentation just needs to be prepared properly from the start, not assembled after something gets rejected. We go into this in more depth in our guide for non-resident founders.
A real example: fast to incorporate, slow to trade
A typical case: a non-resident founder wanted to form an Irish company quickly for an international consulting business. Incorporation itself was never the problem. The delay came from what had not been prepared: no Irish PPS number, no EEA-resident director, and no certified ID or proof of address in the format that the RBO and banking process actually needed.
The client expected the company to be ready to trade once the CRO certificate issued. In reality, RBO, tax registration, the Section 137 bond and the bank account all still had to be dealt with. Once we reviewed the structure, arranged the correct non-resident director route, gathered the right identity documents and guided the RBO and Revenue steps, the process moved forward without further hold-ups. The lesson holds for most cases like this: incorporation can be quick, but being operational takes the documentation being right from day one.

The separate document set your bank will ask for
Bank account opening usually needs its own document set, separate from company formation. Banks and fintech providers commonly ask for:
- Certificate of incorporation
- Company constitution
- Director ID
- Shareholder or beneficial owner ID
- Proof of address
- RBO details
- Business activity description
- Website or trading evidence
- Contracts or invoices
- Source of funds
- Tax residency information
- Expected turnover and transaction details
- Details of customers and suppliers
Requirements vary by provider. Traditional banks tend to ask for more, especially from non-resident founders. Fintech providers can move faster in some cases, but they still carry out due diligence. The CRO accepting your incorporation does not mean the bank will automatically open your account. It is a separate process, with its own document list.
Decisions inside the constitution that are easy to get wrong
The constitution is not just paperwork to sign off without reading. It sits behind how the company is structured and governed, and a few things are worth thinking through before you file it:
- Who owns the shares, and in what proportion
- How many shares are issued
- Whether the company will need investors later
- Whether different share classes are needed
- Who will be director and who will be company secretary
- Whether a second director or a company secretary provider is needed
- What happens if ownership changes down the line
The most common mistake is splitting shares casually at the start, without thinking about what comes next. It is much easier to get the share structure right from the beginning than to unwind it later once investment or a co-founder agreement is on the table.
Do you need to gather all of this yourself, or bring in an accountant?
Our honest view: doing it yourself can work for a simple case. One Irish-resident founder, a straightforward LTD, one or two shareholders, no VAT complexity, no unusual share structure. Plenty of people manage that on their own.
It gets riskier once the founder is non-resident, there are multiple shareholders, VAT or payroll are involved, investment is on the table, or the share structure is not simple. In those cases, the value of using an accountant is not really the paperwork. It is knowing what needs to happen before and after the CRO filing, and having someone look at the company type, share structure, directors, registered office, RBO, tax registration, VAT, payroll, banking and ongoing compliance together, rather than one document at a time.
We go into the DIY question in more detail in our guide on hiring a formation agent versus doing it yourself.
The real question behind “what documents do I need?”
Most of the harder questions we get come from non-resident founders. They are rarely just asking what documents they need. What they are really asking is whether they can set up an Irish company properly without being in Ireland, and what they need to prepare so it does not get delayed.
