Ilmoitin.fi will no longer accept eSARA files after 30 September 2025

The use of eSARA files sent through the Ilmoitin.fi service will end in the fall of 2025, and Kela will accept the last eSARA files on September 30, 2025. We recommend that large employers start preparing now to apply for benefits in the income register. Applying in the income register is easy, but it requires a change in your payroll program.

Ilmoitin.fi and Attachments

• The "Muu liite" type is accepted for the fiscal year ending in 2024, and for the fiscal year ending in 2025, the "Vapaamuotoinen liite" type must be used.
  • If the submission is made using the Ilmoitin.fi browser application, the file name can be anything, as Ilmoitin names the file based on the entered information.
  • If the submission is made via the ApitamoPKI interface, the file must be correctly named, and after the "Vapaamuotoinen liite" phrase, freely chosen text can be added in the same way as it has been for "Muu liite".
• The "Selvitys tutkimus- ja kehittamistoiminnan lisavahennyksesta" attachment can be provided for the fiscal year ending in 2024, and the report is given when using forms 67A and/or 67Y.
• The "Vahvistettu tilinpaatos" attachment type can also be used with forms other than 6B, and only in conjunction with 6B is it forwarded to the PRH. Of course, for forms other than 6B, it would be more appropriate to use the "Tilinpaatos vain Verolle" attachment type, but both attachment types are processed in the same way.
