The Ultimate CRO & Revenue Checklist: What Most Guides Don’t Tell You About Setting Up an Irish Company

The Ultimate CRO & Revenue Checklist: What Most Guides Don’t Tell You About Setting Up an Irish Company

If you are looking to incorporate a company in Ireland, a quick Google search will give you a dozens of generic checklists. They all say the same thing: choose a name, fill out the CRO forms, get an tax registration number, and you’re good to go.

But anyone who has actually gone through the process knows that the gap between “filling out forms” and actually being ready to trade legally and efficiently can be a minefield of delays.

At Shelbourne Accountants, we handle Irish company formations week in, week out. To help you avoid the hidden bottlenecks, we have mapped out the real-world timeline and exact compliance requirements for setting up a Limited Company (LTD) via the Companies Registration Office (CRO) and Revenue.

Phase 1: The CRO Bottleneck (Weeks 1–3)

The Companies Registration Office (CRO) is where your company is legally born. While the paperwork seems straightforward, processing times fluctuate heavily depending on how you submit.

• Step 1: Digital Submission via CORE. All company formations are now managed online through the CRO’s CORE (Companies Online Registration Environment) portal.
• Step 2: Signatures and the PPC Waiting Game. Once your Form A1 is generated, it must be signed. If you are using a digital signature certificate, processing is fast. However, if you are using manual signatures, you are reliant on the CRO’s current post-room processing queues. Expect this to take anywhere from 5 to 15 working days.
• The Hidden Gotcha: Company Name Rejections. The CRO will reject names that are too similar to existing companies, or contain words like “Global” or “International” without proper justification. A rejection puts you right back to the end of the queue.

Phase 2: The PPSN & RBO Hurdle (Parallel to Phase 1)

You cannot legally complete your company setup without addressing anti-money laundering regulations.

• The RBO Filing: Within 5 months of incorporation, you must register your beneficial owners with the Register of Beneficial Owners (RBO). However, we strongly advise doing this the moment you get your CRO certificate.
• The Director PPSN Requirement: To file with the RBO, every director must provide a Irish PPS Number. If you are an international director without a PPSN, you must apply for a VINF (Verified Identity Number Form) via a Form Form VIF. This must be notarised in your home country, which can add weeks to your timeline.

Phase 3: Revenue Registration & The Physical Substance Test (Weeks 3–5)

Once you have your CRO certificate, your company exists, but it cannot trade, hire people, or issue valid invoices until it is registered for tax with the Revenue Commissioners.

This is where many new business owners hit a wall. Revenue no longer rubber-stamps tax registrations. To get approved for Corporation Tax, VAT, or Relevant Contracts Tax (RCT), you must prove your company has physical substance in the Republic of Ireland.

• What Revenue Looks For: They want to see that management and control actually happen here. A virtual office address alone is often not enough anymore.
• Evidence Required: Be prepared to provide proof of a physical trading premises, local commercial contracts, Irish bank account statements, or details of Irish-based employees/directors.
• VAT Registration: If you need a VAT number to trade internationally or clear goods, expect a rigorous review. Revenue will closely scrutinise your supply chain and business plan before issuing an Irish VAT prefix.
