This is the current search tool, but it requires a Norwegian national ID (SSN) to log in: http://www.skatteetaten.no/en/person/Tax-settlement/Search-i...

If you google "skattelister" (tax lists) you will find various other tools:

- This one is based on the 2008 taxes and is therefore completely searchable on name and gives you income/assets/taxes + municipality/age: http://www.biip.no/default.aspx?section=skatt

- This one is based on the latest 2015 taxes: https://www.dn.no/skattelister/. This means that they've used the official tool to search for specific celebrities and published it (together with some general distributions/stats).
