Your Irish subsidiary is approaching its annual return, and the parent already prepares group accounts. Can you attach those accounts instead of publishing a separate Irish set? Section 357 can provide that route, but it involves more than uploading a parent's annual report.
The decision also concerns the parent: a qualifying guarantee accepts responsibility for commitments of the subsidiary for the relevant year. This guide is for directors and group finance teams planning an ordinary Irish private subsidiary's filing. Official sources were checked on 23 October 2026. It is general information, not a guarantee template, an eligibility opinion or advice to sign a legal undertaking. Have Irish company-law and accounting advisers review the actual structure and documents.
Understand which obligation Section 357 changes
Section 357 is an exemption from annexing the subsidiary's own statutory financial statements to its annual return when the conditions are met. It is not a general waiver of Irish company compliance. CRO describes a replacement document package filed with the subsidiary's return, including group accounts and supporting notices.
Keep three questions separate: what the subsidiary must prepare, whether its accounts require an audit, and which documents go on the CRO filing. A positive answer to one does not answer the others. This matters when comparing a quote for accounts preparation with a quote for annual-return presentation.
Nor does this route convert the subsidiary into a branch or erase its separate identity. The practical choice is whether the group is willing and able to satisfy this particular filing exemption for this particular financial year.

| Prepare accounts? | Subsidiary obligations continue |
| Need an audit? | Check a valid audit-exemption route |
| Which CRO attachments? | Assess Section 357 conditions |
| File Form B1? | The annual return remains |
Start with the holding undertaking's legal establishment
The statutory route refers to a subsidiary undertaking of a holding undertaking established under the laws of an EEA state. Do not assume that every overseas corporate shareholder qualifies. A shared trading brand, an EEA sales office or an investor's residence is not the same as the required legal relationship and establishment.
Give the advisers an up-to-date ownership chart, legal entity names, registration details and acquisition dates. Where there is an intermediate holding entity, ask which undertaking could properly support the proposed claim and whose consolidated accounts would be used. Do not choose a convenient group entity without that assessment.
Regulated businesses need specialist review: the legislation's annotations identify restrictions for credit institutions and insurance undertakings. This ordinary-private-company checklist should not be used as a clearance for a regulated entity or a complex reorganisation.
Treat the parent guarantee as a substantive legal commitment
The required guarantee is irrevocable and must be in force in respect of the whole relevant financial year. Its scope includes all commitments entered into by the subsidiary for that year, including amounts shown as liabilities in the statutory financial statements. It is not merely a statement that the parent owns the shares.
Ask the parent's legal and finance teams to review the exposure, corporate authority and execution requirements before approving the filing route. A letter of comfort or a guarantee limited to one banking facility should not be assumed to satisfy the statutory condition. Do not narrow the wording to make it more acceptable without obtaining advice on the resulting eligibility.
Whole-year coverage is not an instruction to backdate a signature. Have counsel assess the document's legal effect and dates, particularly if a company joined or left a group during the year. This article does not conclude that signing late always works, or that a particular execution date is sufficient.
The commercial comparison should include the parent's risk, not just the subsidiary's filing bill. A group may prefer an ordinary filing rather than grant a broad undertaking solely for an administrative benefit.
Shareholder consent is not a majority-vote shortcut
Section 357 requires consent from every relevant shareholder, not just the parent or a 75% majority. The statutory reference identifies shareholders by the next AGM after year-end or the next Annual Return Date after year-end, whichever is earlier. The subsidiary must also notify the relevant shareholders in writing of the guarantee.
Ask the secretary and legal adviser to identify the correct shareholder population and evidence the consent and notifications. An incorporation-date shareholder list may be stale after a transfer or investment. Do not assume that the person coordinating the group's accounts can consent for everyone.
For a fictional subsidiary with a parent and a minority investor, obtaining the parent's signature alone would not settle the consent condition. Raise the minority investor's participation early, while there is time to organise a different filing approach if the necessary agreement cannot be obtained.
Use consolidated accounts, not just the parent's own accounts
The subsidiary's financial statements for the year must be consolidated into the holding undertaking's consolidated accounts, and those group accounts must disclose the subsidiary's exemption in a note. The statutory conditions also require the specified reporting framework, an audit and the auditor's report accompanying the consolidated accounts.
Parent entity-only accounts are not automatically a substitute for a consolidated set. Section 294 describes group financial statements dealing with the undertakings included in consolidation as a whole. A group reporting spreadsheet or an internal management pack is not evidence that the required statutory package is ready.
Confirm with the group accountant which version will be final, whether the subsidiary and correct period are included, and who will check the exemption note. If the parent normally prepares unaudited accounts, do not assume that its own exemption removes the audited-consolidated-accounts condition for this route.
Build the document package before opening the filing screen
CRO lists separate documents for the subsidiary's annual return. Use the list as a coordination aid, then have the adviser confirm the precise content, signatures and certification required for your company. Uploading only the parent's annual report leaves other conditions unresolved.
- A notice that the subsidiary is availing of Section 357 for the relevant year.
- A copy of the qualifying irrevocable parent guarantee.
- The written notification to shareholders about the guarantee.
- The subsidiary's declaration that all relevant shareholders consented, signed by a director or secretary.
- The qualifying audited consolidated accounts, exemption note and auditor's report.
Subsidiary accounts and accounting records still need attention
Section 290 requires directors to prepare entity financial statements for each financial year. Section 281 separately requires adequate accounting records. Section 357 concerns annexing documents to an annual return; it should not be used to stop the subsidiary's bookkeeping or local financial-statement preparation.
Keep the Irish ledger, reconciliations and intercompany balances in a form that supports the local accounts and the group consolidation. Assign someone to explain differences between the subsidiary's records and consolidation adjustments. A parent finance team's reporting deadline is not proof that Irish requirements have been completed.
Audit is another assessment. Section 333 requires statutory audit unless the company is entitled to, and chooses, an applicable audit exemption. Do not tell the local accountant to cancel an audit merely because a Section 357 package is being considered. Ask which audit obligations remain and record the conclusion.
Plan the annual-return timetable and document language
CRO requires an annual return and its required attachments to be delivered together as a complete filing. Its guidance provides a 56-day delivery period after the return's effective date, with financial-statement timing also relevant to the applicable deadline. Have the presenter confirm the actual deadline rather than treating the Annual Return Date itself as the last filing day.
Parent accounts still being audited, a guarantee awaiting approval or a missing consent do not automatically pause that timetable. Build a backwards plan with dates for group completion, legal review, translations, subsidiary approvals and presentation. Discuss an alternative compliant filing if a necessary item will not be ready.
Section 357 also addresses documents not in Irish or English: the required certified translation must accompany the relevant document. Do not assume an informal summary, selected translated pages or an AI translation satisfies that requirement. Confirm the prescribed certification and arrange it early.
Before lodging, consider the disclosure consequence of attaching group accounts. This is a filing package for the CRO record, not a private substitute sent only to your accountant. The group should understand what it proposes to lodge and approve the final version.
A practical decision example for a group finance team
Imagine an Irish subsidiary whose group wants to use the parent-account filing route. The parent has approved its own accounts, but a consolidated audit is not yet complete and the subsidiary has recently admitted a minority shareholder. No conclusion follows simply from the parent being established under EEA law.
The team should identify the relevant shareholders, settle the consolidation and audit position, seek legal advice on the guarantee, and confirm the return's deadline. It should also agree a fallback with the Irish accountant if the Section 357 conditions cannot be completed in time.
Compare the work on both routes before deciding. A smaller local filing is not automatically more expensive overall, and a larger group attachment is not automatically more confidential. The right choice depends on eligibility, disclosure, parent's willingness to guarantee, professional costs and the timetable, not a promise that one route always saves money.
Agree service scope before ordering annual-return support
StartCompany.ie's Annual Returns service provides B1 preparation and filing support, including attachment of the required financial statements where applicable. A routine B1 order does not automatically include drafting a parent guarantee, a Section 357 eligibility opinion, consolidation, statutory audit or certified translation.
Contact the team before ordering a group-exemption filing. Explain the structure, year, deadline and which documents the group's advisers have already completed. Ask what support can be provided and agree the scope and total payable, with responsibility for specialist legal and accounting work stated separately.
Retain the approved package, advice on eligibility and evidence of completed delivery. Reassess the route for each year instead of copying a previous attachment unchanged after a change of shareholder, parent, reporting framework or group structure.
