B1 Annual Returns & CRO Filing

Company Secretarial, CRO, Corporation Tax, Corporate Clients, Company Accounts

Every company must file a B1 Annual Return and financial statements with the Companies Registration Office (CRO) every calendar year, except for their first B1 or when extending an Annual Return Date (ARD).

Annual Filing Requirements

Every company must file a B1 Annual Return and financial statements with the CRO Annual Return Portal each calendar year.

• Exceptions: A first-time B1 filing skips financial statements, and companies can extend their Annual Return Date (ARD) using a Form B73.

Determining Company Details

The Annual Return Date (ARD) dictates the exact company information required for the B1 filing.

• The Snapshot: Form B1 captures statutory details—such as directors, secretaries, and share capital—precisely as they exist on that specific ARD.

Reporting Post-ARD Changes

You must exclude any changes occurring after the ARD from your current filing.

• Next Steps: You report these changes on the following year’s B1 return. However, you must still submit standalone event forms (like a Form B10 for a director change) independently within 14 days of the actual event.

Submission Platform

Most presenters use CORE to submit their B1 forms.

• Live Data: The portal pulls official data directly from the central CRO database to complete form fields automatically.

Process Simplification

CORE speeds up filing by providing pre-filled B1 forms.

• Automation: The system automatically includes any company updates officially registered with the CRO over the previous 12 months.

Risks of Pre-Filled Forms

Relying blindly on pre-filled data submits outdated or incorrect information.

• Compounding Errors: Companies repeat compliance mistakes year after year if they fail to manually verify and update unverified form fields.
