The Financial Supervisory Authority of Norway has announced a change to the submission format for Annex IV reporting under the Alternative Investment Fund Managers Directive, requiring reports to be filed using XML file attachments from the reporting reference date 30 June 2026. The requirement will apply to registered and authorised alternative investment fund managers, and to non-EEA managers permitted to market alternative investment funds in Norway. Annex IV reporting has to date been possible via tailored Altinn forms that can be completed manually, alongside a parallel XML attachment solution offered since 2020. As part of the phase-out of the Altinn II platform and the transition to Altinn 3, the supervisor will not develop new Altinn forms for this reporting and will instead mandate XML reporting for both manager-level reporting (KRT-1161) and fund reporting (KRT-1160). From 1 June 2026, the existing reporting solution will cease, and new outstanding submissions and corrections to historical reports must be delivered as XML attachments via new simplified Altinn forms, with a separate XML file uploaded per fund and for the manager. Submissions must follow ESMA’s technical specifications, with reference to the AIFMD Reporting IT Technical Guidance (Revision 6) covering mandatory fields and structural requirements for the XML format. The authority will update its website with further information and guidance and recommends that managers not yet using XML begin preparations well in advance.
