How do I file the annual return B1 with the CRO in Ireland?

## How Do I File the Annual Return B1 with the CRO in Ireland?

Every company incorporated in Ireland under the Companies Act 2014 must file an annual return (Form B1) with the Companies Registration Office (CRO). This is a statutory requirement separate from your tax returns to Revenue and is not optional regardless of whether the company traded or not.

## What Is the Annual Return Date (ARD)?

Your Annual Return Date (ARD) is the deadline by which you must file your B1. For newly incorporated companies:

• First ARD: six months after incorporation
• Subsequent ARDs: the same date each year

For example, if your company was incorporated on 1 March 2024, your first ARD is 1 September 2024. Your next ARD will be 1 September 2025, and so on.

You have 28 days from your ARD to file the completed B1. Filing must be completed, not just started, within this window.

## What the B1 Contains

The B1 annual return includes:

• Registered office address
• Details of directors and secretary (name, address, date of birth, consent to act)
• Details of company secretary
• Shareholding structure and share capital
• A statement confirming the company has made disclosure as required

For most years, the B1 must be accompanied by financial statements (abridged accounts for small companies eligible for the audit exemption, full statutory financial statements for larger companies). The first B1 after incorporation does not require financial statements if filed within six months.

## Fees

• **Online filing via CORE:** €20
• **Paper filing:** €40

Always file online through the CRO's CORE portal to pay the lower fee and benefit from faster processing.

## Consequences of Late Filing

Late filing of the B1 is one of the most common and costly compliance failures for Irish companies.

Late filing fee: €100 for the first day late, plus €3 per day thereafter, up to a maximum of €1,200 per return.

Loss of audit exemption: If a company files its annual return late, it loses its right to the audit exemption for the following two years. For small companies, an audit typically costs €3,000 to €8,000, making a late filing far more expensive than the direct fine.

Potential strike-off: Persistent failure to file annual returns can result in the CRO striking the company off the register, which means the company ceases to legally exist. Restoring a struck-off company costs several thousand euro in legal fees.

## Who Must Sign the B1?

The B1 must be signed by a director and the company secretary. Both must provide consent to their appointment if they are new to the company. Directors cannot sign on behalf of the company secretary unless separately authorised.

## How to File

• **Log in to CORE** (core.cro.ie) using your company's CRO number
• **Select Form B1** from your company's filing dashboard
• **Complete all sections**, updating any changed information on directors, secretary, or registered office
• **Attach financial statements** (required for most filings after the first year)
• **Pay the €20 fee** by debit or credit card
• **Download and retain** the filing confirmation

## Audit Exemption Criteria

To qualify for the audit exemption (and avoid a mandatory audit), your company must satisfy at least two of the following three criteria:

• Turnover not exceeding €12 million
• Balance sheet total not exceeding €6 million
• Average number of employees not exceeding 50

The company must also have filed its annual returns on time for the current and preceding year. A single late filing removes the exemption for two years.

## Practical Tips

Set a calendar reminder three months before your ARD to begin preparing financial statements. The financial statements must be approved by the board and signed before the B1 can be filed, so leaving preparation until the last week often leads to missed deadlines.
