This article is for Irish company directors and secretaries who've discovered errors in their CRO filings and need to fix them quickly.
If you're wondering how to correct mistakes like wrong director addresses, financial statement errors, or share capital problems, this guide covers how to use Form H1, what can't be fixed with corrections, and why prompt action matters for your company's reputation and legal compliance.
Key Takeaways

What Are the Most Common Filing Mistakes?
Directors and company secretaries make predictable errors when filing CRO documents. Understanding common mistakes helps you identify problems in your own filings and prevent future errors.
- Director address errors: top the list. The Companies Act 2014 requires accurate director residential addresses on the register. Directors often provide old addresses after moving house or mistakenly list business addresses instead of residential ones. The CRO publishes these addresses, making accuracy important for legal notices.
- Financial statement errors: include wrong figures in accounts, missing pages from uploaded documents, or attaching financial statements for the wrong period. These mistakes create public records showing inaccurate company financial positions. Banks and credit agencies review filed accounts, making corrections important for maintaining creditworthiness.
- Share capital mistakes: happen frequently. Companies report incorrect numbers of issued shares, wrong share classes, or fail to update shareholdings after transfers. The Companies Act 2014 requires accurate member registers, and filed documents should match these records.
- Annual return date confusion: causes problems when companies file returns for wrong periods or calculate filing windows incorrectly. The 56-day filing window from your Annual Return Date confuses directors who think it runs from year-end instead.
- Missing signatures: on financial statements or Form B1 director consents render filings defective. Directors are required to sign financial statements. Without proper signatures, the filing doesn't comply with legal requirements.
What Happens If You Don't Correct Errors?
Uncorrected errors create both legal and practical problems that compound over time.
Incorrect public records mislead third parties. Anyone searching the CRO register sees your filed documents. Banks reviewing credit applications, suppliers checking creditworthiness, and potential investors conducting due diligence all rely on CRO information. Errors damage your company's reputation and can result in refused credit or lost business opportunities.
Legal notices sent to wrong addresses miss directors. If your filed director address is incorrect, court documents, tax notices, or creditor communications might go to the wrong location. You're still legally bound by these notices even if you never received them due to address errors.
The practical consequences include:
- Regulatory compliance issues arise from inaccurate filings - Revenue uses CRO information to verify company details
- Inconsistencies between CRO records and Revenue filings trigger queries and potential investigations
- The Companies Registration Office may question patterns of errors
- Audit exemption problems can result from financial statement errors showing turnover exceeding thresholds
How Do You File Form H1 Corrections?
Form H1 provides the mechanism for correcting most CRO filing errors. The Registrar has legal power to accept corrected documents when original filings contained errors or omissions.
The correction process follows specific steps:
- Access Form H1 through your CORE account by logging in and selecting "File a Document"
- Identify the document you're correcting using the CRO reference number from the original filing
- Explain the error clearly - be specific about what was wrong and what should have appeared
- Attach corrected documents where necessary, particularly for financial statements
- Pay the filing fee online or by post
Processing times vary by submission method. Online filings through CORE process in a few business days. Postal submissions take longer. The CORE system provides confirmation once the correction is accepted.
What Can't Be Fixed With Form H1?
Some errors require different correction procedures than Form H1. Understanding these exceptions prevents wasted time filing ineffective corrections.
Constitutional amendments need special resolutions and Form G1, not Form H1. If your company constitution was filed with errors, you must pass a special resolution amending the constitution and file Form G1. Simple H1 corrections don't work for constitutional documents.
Several other filings have their own correction procedures:
- Director appointments and resignations use Forms B10 for corrections
- Annual returns for wrong periods need the correct annual return filed for the right period
- Special resolutions require new resolutions rather than administrative corrections
Are There Time Limits for Making Corrections?
The Companies Act 2014 doesn't impose specific time limits for filing H1 corrections. However, practical considerations make prompt corrections important.
Third party reliance increases over time. Every day incorrect information remains on the public register, more people potentially view and rely on it. Credit agencies update their databases quarterly based on CRO information. Waiting months to correct errors means incorrect data spreading to multiple third-party systems.
The practical reasons to correct quickly include:
- Evidence becomes harder to gather - accounting records and staff who prepared documents may not be available months later
- Pattern recognition by the CRO - repeated late corrections might trigger additional scrutiny
- Current compliance deadlines - corrections affecting small company status need completion before next year's filing
What About Third Parties Who Relied on Wrong Information?
Third parties who rely on incorrect CRO information before corrections are filed create potential liability issues.
The law protects relying parties in many circumstances. Someone who deals with your company based on CRO information is entitled to assume that information is accurate. If they suffer losses because filed information was wrong, they might have claims against your company.
Director liability can arise in extreme cases. If directors knew information was wrong but delayed corrections while third parties relied on incorrect filings, those directors might face personal liability. Directors are legally required to act honestly and responsibly.
Risk management strategies include:
- Direct notification to affected parties when material errors are discovered
- Contact banks immediately if they relied on incorrect financial statements
- Professional indemnity insurance might cover losses from filing mistakes
- Prompt error disclosure to insurers if errors might result in claims
