A-melding is Norway's unified payroll report — a single submission covering the Tax Administration, NAV and Statistics Norway. It must be submitted monthly by the 5th for the previous month's payroll. 4b2b aggregates payroll data, calculates tax withholding and employer contribution, and submits the finished A02 file to Altinn 3 with no manual work.
You have 15 employees across different employer contribution zones (zone I, II, III).
Each employee is linked to their workplace zone. Employer contribution is calculated per zone (14.1 % standard, 10.6 % zone II, 6.4 % zone III) and reported separately in the A-melding.
An employee starts mid-month — how do you report the employment?
Start date and FTE percentage are set on creation. A-melding reports the employment with the correct from-date. End dates are supported for ending employments.
The Tax Administration rejected the A-melding — you need to find and fix the error.
Each submission returns a receipt with any discrepancies. Issues are shown in plain text (e.g., "national ID missing check digit") with a direct link to the employee/issue.
You must correct a payroll from the previous month — how?
A correction A-melding is generated with the delta. Previously reported amount + new value handled automatically. The Tax Administration updates the tax settlement on the next submission.
The entire 4b2b ecosystem is built for the Norwegian market — from EHF invoicing to SAF-T export and A-melding. You don't need to integrate against Altinn yourself.
