A-melding tax report Norway

All you need to know about the Norwegian tax report system – a-melding

Foreign enterprises with business activities in Norway must declare employment- and income information for their personnel by using the a-melding.

Do you have employees working in Norway? Foreign enterprises with business activities in Norway are obligated to declare employment and income information for personnel working in Norway. This also applies to personnel who are non-taxable to Norway.

The system for reporting tax in Norway is called a-melding and must be submitted electronically every month.

What must be reported on the a-melding

The a-melding should contain information about:

  • salaries
  • pension
  • remunerations
  • tax deducted
  • employments in the given period

Status of employment must be declared, even if the employees have not received a salary/remuneration.

An income recipients’ leave of absence must also be declared if it continues for 14 days or more. Both paid and unpaid leave of absence must be declared.

How to submit the a-melding

The a-melding is submitted through Altinn – the official Norwegian online portal.

This can be done in one of the following ways:

  1. An accountant, advisor, solicitor or another representative with access to Altinn can submit the a-melding for you
  2. You can register the a-melding directly in Altinn
  3. You can submit the a-melding from an Altinn-integrated payroll system

Please note that you are no longer allowed to submit the a-melding on paper.

The a-melding is sent from the legal unit (organization) registered in the Register of Legal Entities. Consequently, the system cannot be used unless the enterprise has applied for and received a Norwegian organization number.

Due dates

The a-melding must be submitted by the 5th of the month after the payouts were made. If the 5th is a Saturday, Sunday or a public holiday, the deadline is the next working day.

Example: Information about salaries paid out on the 21st of March must be submitted on or before the deadline, 05th of April. It does not matter if these salaries are March salaries or payments in arrears for February. The a-melding submission deadline is determined by the payout date.

The employer can submit the a-melding as often as they want. This is usually done if they have several payout dates in a month.

Note that tax amounts must be transferred to the tax office bi-monthly within the 15th of the following tax period.

The tax office carries out automatic checks for every a-melding that is submitted.

The feedback states what was reported and highlights errors which must be corrected. The feedback also contains information on payments of the employer`s National Insurance contributions and payroll withholding tax, accountant number, and KID number. It is therefore important to check the feedback.
