Norway: Altinn Access Roles to Expire by December 31, 2026

Norway will discontinue its old Altinn access roles by December 31, 2026, requiring businesses to renew most authorizations through access packages or individual services. Some services will lose role-based access earlier, potentially affecting tax filings, accounting tasks and other administrative procedures.

Norway’s digital government platform Altinn has announced that all remaining legacy Altinn roles will cease to function by December 31, 2026, as part of the transition to a new authorization management system.

Altinn reminded businesses and individuals that previously granted access rights will not necessarily transfer automatically. Anyone who continues performing tasks on behalf of a business may need new authorization through an access package or an individual service.

Although December 31 is the final deadline, several public authorities are already withdrawing access through old roles. Some businesses may therefore lose access to particular services before the end of the year.

Altinn is Norway’s digital platform for accessing public services, submitting official forms, and exchanging information with government authorities.

Under the previous system, businesses could assign predefined roles, allowing employees, accountants, auditors, and external representatives to perform specific activities.

These legacy roles are being replaced by more targeted authorizations.

An access package provides permission to use a group of related services, while an individual service authorization grants access to a particular form, message, or administrative task.

The transition means businesses must generally issue new authorizations to users who still require access.

The authority to grant them normally belongs to the chief executive officer, chairperson of the board, or main administrator. Users holding appropriate access-management permissions may also delegate services or access packages they are authorized to manage.

Businesses can review existing permissions by logging into Altinn and opening the Access Management section.

The new system is intended to allow businesses to assign access according to the tasks users actually perform rather than relying on broader predefined roles.

Altinn has published a timetable identifying services for which access through legacy roles will disappear before the final deadline.

The phase-out is already underway, with several services affected from October 20, 2026.

Further changes are scheduled for November 3, November 17, December 1 and December 15, before the remaining legacy role-based permissions expire on December 31.

The timetable includes services provided by the Norwegian Tax Administration, the Norwegian Labour Inspection Authority, the Norwegian Labour and Welfare Administration (NAV) and other public authorities.

For businesses, the November changes are particularly relevant.

From November 17, 2026, legacy role-based access is scheduled to end for several Norwegian Tax Administration services, including employment-related reporting through a-melding, tax returns, tax deduction cards and tax assessment information.

Other tax administration services not included in earlier transition dates are scheduled to lose legacy role-based access on December 31.

The published timetable is not exhaustive and may be updated as service owners complete their transitions.

Altinn confirms that certain existing permissions will transfer automatically to the new authorization system.

These include the administrative roles of Main Administrator, Client Administrator, and Access Manager.

Specific accountant and auditor permissions will also continue automatically where the relevant professionals are registered in Norway’s Central Coordinating Register for Legal Entities (Enhetsregisteret).

The same principle applies to registered business managers of housing cooperatives and owner-section condominiums.

For private individuals, the authorization category covering personal tax matters will transfer automatically only where the authorization was granted from March 2021 onward.

However, automatic transfer does not guarantee access to exactly the same services as before.

Businesses must verify that transferred permissions cover the activities their employees or external representatives still need to perform.

Where an external accountant received access through an old Accounting Employee role but is not registered as the business’s accountant in the Register of Entities, a new authorization will generally be required.

Impact on retailers and POS providers

The Altinn transition affects businesses that rely on external accountants, tax consultants, payroll providers, or other representatives to complete administrative obligations.

For retailers, retail chains, e-commerce businesses, and hospitality operators, the immediate concern is maintaining access to government services used for tax and business reporting.

A business may have assigned Altinn roles to employees at its headquarters or to external accounting providers responsible for regulatory submissions.

If those permissions expire without replacement, the authorized representative may no longer be able to access the relevant service or submit information on the business’s behalf.

The transition may also affect access to historical messages and submitted forms where permissions depend on discontinued roles.

What should businesses do?

Businesses should log into Altinn, open Access Management, and review which employees, accountants, auditors, and external representatives currently hold authorizations.

Where legacy permissions will not transfer automatically, the chief executive officer, board chairperson, or authorized administrator should grant replacement access packages or individual service permissions.

Businesses should also verify accountant and auditor registrations in the Register of Entities, check access to previously delegated services, and review the phase-out dates for government services they use.

These checks should be completed before the relevant services discontinue legacy role-based access, which may occur earlier than December 31, 2026.

From a retail compliance perspective, the main risk is administrative continuity rather than changes to transaction processing. Businesses should ensure that the people responsible for regulatory submissions retain access when the old authorization system is withdrawn.
