'The file type financial entities must be using is a XBRL OIM-CSV file in accordance with EBA DPM 4.0' saved as a .zip; ESAs confirmed in Dec 2024 that no template or conversion tool would be provided. The Portal offers 'Download Excel' to view a submitted register but does not accept Excel.

CCCCCCC_YYYYMMDD_CBIREGISTERNAME.zip (CBI-specific; NOT the ESA pattern)

Example C999001_20251231_DORAREG_MiFID.zip (test MiFID firm C999001; 2026 cycle reference date 20251231). 2025 example in portal emails: C999001_20250331_DORAREG_MiFID.zip

Notes CCCCCCC = the entity's C code: 'the numerical section of the financial entity's number preceded by C and NOT the institution number. Where the institution number is CBI0012345, the C Code will be C12345' (leading zeros dropped). YYYYMMDD = reference date (20251231 for the Q1 2026 submission). CBIREGISTERNAME = 'the name of the register as outlined in this guide and as displayed on screen when you are loading a return'; the guide documents 'DORA Register MiFID' -> DORAREG_MiFID; other sector register names are shown on the upload screen and are not listed in the published guide text. No spaces in the filename. The inner root folder must carry the same name as the zip (minus .zip).

Notes Industry briefing 4 Feb 2026 (800+ attendees; recording https://youtu.be/KbyLfbulaQU; slides pptx 18.44 MB). Insurance newsletter Dec 2025 had said 'between February and March 2026'. 2026 Portal shows multiple errors at once and distinguishes blocking vs non-blocking (commentable) errors.

reference date 2025-12-31

opens 2026-03-02 (RoI page 'Upcoming Submission Date' section says 2-31 March 2026; another section of the same page and the guide say 'between 1 and 31 March')

deadline 2026-03-31

corrections until EBA technical-validation feedback had to be addressed and registers resubmitted before 31 March 2026; EBA Data Quality checks ran in April 2026 with CBI-requested resubmissions afterwards (Forvis Mazars reports resubmissions through April-May 2026)

reference date 2026-12-31

esa transmission deadline 2027-03-31

announced no

changes Nothing published by the CBI as of 31 Oct 2026 (RoI page, Communications page and FAQ carry no 2027 statement). Forvis Mazars Ireland 'expects' the portal to open 1 March 2027 with submissions due 31 March 2027 (expectation, low confidence). Standing ESA rule: CAs transmit by 31 March with 31 December reference date (ESA Decision 2024/22 Arts 4-5).

No test environment or dry-run window is mentioned in the 2026 guide or on the RoI page; the guide's screenshots use a 'CRDIV Test Firm 1 (C999001)' internal test entity. CBI encourages firms to 'frontload their initial submission early in the collection window'.

Three-step process: (1) Load File -> status Processing/Validating -> Accepted or Rejected (confirmation email to uploader only; 'accepted with warnings' possible); (2) Finalise by the editor; (3) Sign-Off by the verifier with a declaration checkbox. After sign-off the return is locked; a Verifier can request an auto-unlock ('Create Request' > 'Unlock Return') to resubmit.

two user yes

roles Editor uploads and finalises; a different user with Verifier access signs off ('the same user cannot finalise and sign off the upload'). Editor & Verifier can do both but not for a return they finalised.

format Portal: file status Accepted/Rejected; 'Warnings' html inside a zip (download via View Uploaded Files); 'Xbrl Non Blocking Rules Report' table (EBA rule code, description, template, offending value, column, technical description, 'Explanation' column to be filled before finalising). EBA feedback (NOK/RES zips with instance-status.csv and detailed-feedback.csv) relayed by the supervisor via Portal Secure Messaging.

timing 'the majority of files should be processed within five minutes'; EBA feedback after CBI forwards the file (no SLA given).

resubmission Correct, unlock if already signed off, re-upload (filename pattern unchanged, same reference date). 'The Central Bank of Ireland will not troubleshoot issues within reporting packages.'

'Financial entities submitting a RoI must have a valid LEI code'; the Portal matches the C-code against the LEI in parameters.csv and GLEIF. For ICT providers the LEI requirement is non-blocking ('we believe this still applies for 2026'); alternative identifiers per EBA FAQ 39/47 are flagged as DQ issues only.
