Norway Corporate Tax Return Deadline: Which Filings Are Due and When

Which Norwegian company filings are due and when — the corporate tax return (skattemelding), annual accounts, and VAT (MVA), computed in Oslo time.

[Cite this as: Apier.no Docs v0.1.0 — last updated 2026-06-28]

A Norwegian company (AS) files its corporate tax return (skattemelding) electronically by the statutory deadline of 31 May.

The manual process today

A company has not one deadline but several, each on a different government surface, each in its own cadence — and each has to be located, then adjusted for weekends and holidays, by hand.

Each must be computed in Oslo time and adjusted for weekends and public holidays by hand. Confirm each against the authoritative source — for the corporate tax return, see Skatteetaten's guidance for companies.
