Skatteetaten Shareholder Register

Name: Skatteetaten Shareholder Register
License: NLOD

The Shareholder Register provides the complete ownership structure of Norwegian limited companies: shareholder names, birth year/org number, share class, number of shares and ownership stake — reported as of 31 Dec each income year. Combined with brreg it yields complete group maps and investor analysis. The Maskinporten API requires a data-processing agreement with Skatteetaten; manual CSV extracts are supported as a short-term alternative. Without configuration the connector returns a structured 503 not_configured. Issue #1133.
