  • Changes to background checking:
    • If a user submits multiple files and even one of them is larger than 5 MB (or 1 MB for XML files), they will now be given the option to submit them to background processing.
    • Due to data security concerns, error codes have been removed from the e-mail sent to the user after the checking has been completed. Users can view the errors on Ilmoitin.fi as follows:
      • If the filing was submitted while logged in: go to "Archive", select "Large filings for background checking", and click "Errors".
      • If the filing was submitted via the background checking functionality without logging in, the file containing errors must be checked again without submitting it to background processing: go to "Submit for background checking" and select "I want to launch the check process immediately".
  • The data format specifications for annual information returns for the 2024 reporting year are published on 5 February, but their formats will not be available until the March version of Ilmoitin.fi is launched on 26 March 2024. The specifications are available on vero.fi.
