SAF-T submissions move to an online form and end-user systems

SAF-T Financial files can now be submitted to Skatteetaten through an online form or directly from end-user systemsSkatteetaten. Version 1.8 of the general documentation, dated 31 August 2026, identifies these as the new submission methodsSkatteetaten and says Altinn is no longer available as a submission channelSkatteetaten. Accounting teams and software providers should distinguish the place where an audit notice arrives from the channel that receives the files.

The online form is linked from the audit case's message thread. The documentation describes access through My Page or the Altinn inbox and states that an audit notification is required before files can be submittedSkatteetaten. An Altinn message can therefore still provide access to the case even though the files are submitted through the new form.

Each submission can contain up to 20 files, with a maximum size of 2 GB per file. Several submissions can be made for the same audit. Each XML file must validate against the relevant XSD schema. The documentation also explains that there is no automatic validation of key references, so successful schema validation should not be read as confirmation that all references within the accounting data are consistent.

If file-size limits or other technical constraints prevent the ordinary submission methods from being used, the documentation provides for an alternative such as ShareFile arranged through the tax auditor. Teams should resolve that route with the auditor handling the case.

The submission change sits alongside the existing schema-version timetable. Version 1.20 can be used for financial year 2024 and earlier; version 1.30 is required from the accounting period beginning on 1 January 2025Skatteetaten; and version 1.40 is required from the accounting period beginning on 1 January 2027Skatteetaten. Those dates relate to the accounting period covered by the data, rather than simply the date on which a historical file is uploaded.

The applicable submission instructions are set out in Skatteetaten's Norwegian SAF-T Financial data general documentation, version 1.8, read with its technical description and documentation index.
