Altinn is a web portal for reporting to public agencies. The portal is a collaboration between the Brønnøysund Registers and the Directorate of Taxes, among others.
At Altinn.no, forms can be submitted to the tax authorities, including the reporting of foreign labour, VAT statements, tax returns, statements relating to the tax assessment, employers’ payment record form for National Insurance contributions and payroll withholding tax. Forms can also be submitted to other public agencies. A list of all the forms in Altinn is available at www.altinn.no/no/Skjema-og-tjenester/. More information about the tax authority’s forms is available at skatteetaten.no.
