It's semi-public.

Previously, up until 2010-ish?, newspapers etc. could ask for the public tax records from the government and make them searchable.

Now that's not possible, but they are free to list the 10-50-100 richest people in each municipality, the sports people earning the most, the business mean with the highest wealth or lowest tax etc.

Everyone can still look up individuals, though, but they have to log in to a government portal to do it, _and_ the individual being looked up will be notified about it, and who did it.
