[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.
| Obligation | Where you look | Manual pain |
|---|---|---|
| Corporate tax return (skattemelding) | skatteetaten.no | find the date, adjust for weekends |
| Annual accounts (årsregnskap) | brreg.no / Altinn | separate deadline, daily late fees |
| VAT (MVA) terms | skatteetaten.no / Altinn | multiple periods through the year |
| Other filings (a-melding, etc.) | Altinn | vary by entity type |
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.
