Irish CRO documents are individual statutory filings, not interchangeable versions of one company report. A B1 gives an annual snapshot, financial statements show historical accounts, a B10 records officer changes, a B2 changes the registered office, and C1-series filings record registrable mortgages or charges. The useful document depends on the question you are trying to answer.
Start with identity, then choose evidence: confirm the legal company name and CRO number first. Review the filing timeline before buying a document so you select the correct form, filing date and financial period. A €9.99 Irish company report can provide the initial company, officer and filing overview; use CRO CORE when you require the official filed document.

What is a B1 annual return?
The CRO describes Form B1 as an electronic annual return that every Irish company must normally deliver at least once each year, whether it is trading or not. It provides a snapshot as at the return date rather than a live diary of every event during the year.
A B1 can help you confirm the registered office, directors and secretary, share-capital or member information where applicable, and the date to which the return was made up. Read the document alongside later B2 and B10 filings: an address or officer shown on an older B1 may have changed after that annual snapshot.
A company's first annual return is normally made up to a date six months after incorporation and does not have financial statements attached. The absence of accounts from that first return is therefore not evidence of non-compliance. Our guide to the Irish annual return date explains the timing in more detail.
Financial statements: the document most buyers actually mean by “accounts”
Financial statements relate to a defined accounting period. Depending on the company and exemptions claimed, the public filing may include a balance sheet, profit-and-loss information, notes, a directors' report and an auditor's report—or a reduced set of information permitted for a qualifying company.
Before relying on the figures, record the financial year end and the date you are making the decision. Filed accounts are historical. They do not show the company's bank balance, unpaid invoices or trading performance today. Smaller companies may file abridged or micro-company information, which can remove the profit-and-loss detail a credit reviewer hoped to find.
Compare at least two periods where possible. Look for movements in cash, current assets, short-term liabilities, net assets and retained earnings. Read the notes and auditor's report rather than relying only on headline numbers. See our practical guide to reading Irish company financial statements.
B2: change of registered office
Form B2 notifies the CRO of a change to the company's registered office. The registered office is the legal address for official notices and is not necessarily the trading premises, warehouse or place where staff work.
A sequence of address changes can be commercially relevant, but it is not an automatic warning sign. Companies move, use professional registered-office agents or change advisers. Compare the filed address with the contract and invoice, ask for an explanation where they differ, and independently confirm delivery or service locations when they matter.
B10: director and secretary changes
Form B10 is used for changes involving a director or secretary, including an appointment, cessation or change in particulars. It is the key form when you need to understand whether a person joined or left after the last B1 annual return.
Read appointment and resignation dates carefully. A former director should not be presented as a current officer merely because their name appears on an old filing. Conversely, a director does not automatically own shares or beneficially own the company. Officer status, legal authority and ownership are different questions. Use the company-director checker before ordering a specific form.
B5 and other share-capital filings
Form B5 is a return of allotments. It can provide evidence of newly allotted shares, but it is not a complete, continuously updated ownership register. To investigate historical ownership, reviewers may need annual returns, associated shareholder lists, share-capital forms and the company's statutory register of members.
Do not treat the latest visible shareholder list as guaranteed current beneficial ownership. Transfers, nominee arrangements and the timing of annual returns can complicate the picture, while public access to personal beneficial- ownership information is restricted. Read our guide to Irish company shareholders and beneficial owners.
C1, C1A/C1B and C3: mortgages and charges
A C1 records prescribed particulars of a mortgage or charge created by an Irish company. The two-stage C1A/C1B procedure is an alternative registration route, while C3 concerns a charge affecting property acquired by the company. These filings can identify the secured party, dates and property or undertaking described by the security.
A registered charge does not prove that the company is distressed, and it does not normally give you a live loan balance. Healthy businesses use secured bank, property and asset finance. The useful questions are what appears to be secured, who holds the security, whether later satisfaction filings exist, and how the borrowing fits with the accounts and the proposed transaction.
C6 and C7: satisfaction is not the same as deletion
A C6 records full satisfaction of a charge or judgment mortgage. A C7 concerns partial satisfaction or release of specified property. Check the exact charge referenced by the filing and whether the release is full or partial.
The absence of a satisfaction filing does not conclusively prove that a current balance remains unpaid; it means you should not assume the charge has been released. For a material loan, acquisition or property decision, obtain current evidence and professional advice.

A five-step document-buying workflow
- Confirm the company. Match the legal name, CRO number, company type and registered address.
- Write down the question. Identity, current officer, historical accounts, ownership evidence and secured lending require different documents.
- Read the filing timeline. Identify the correct filing date and accounting period before paying for a document.
- Check later filings. A later B2, B10, C6 or C7 may change how an earlier document should be interpreted.
- Record limitations. Note the document date, missing current information and any evidence requested directly from the company.
Common mistakes when reading CRO documents
- Assuming a filing date and the effective date of the reported event are identical
- Treating an annual return as a live record after later changes
- Expecting the first six-month B1 to include financial statements
- Calling every registered charge an unpaid or problematic debt
- Using a B10 directorship filing as proof of share ownership
- Comparing accounts without checking the financial period or exemption used
- Buying several documents before confirming the company's CRO number
Start with the company overview
Search the company for free to confirm its identity and see the available filing history. When you need the public company, officer, filing and available financial information consolidated for review, order an Irish company report for €9.99. Use the filing dates in that overview to decide whether you also need an official B1, B10, financial statement or charge document from CRO CORE.
