The underlying reason is that we have a default that says that all documents produced by the different levels of government is public by default. This allows journalists and other investigators to expose bad stuff that is going on. Also note that just because something nominally is public, it doesn't automatically mean it is easily accessible. It can mean you have to go somewhere, submit forms and pay for the induced work load to produce the documents. Things can still be made secret if there are actual reasons to do that, like privacy reasons or security reasons etc. Taxes have traditionally not been counted into the things that require privacy here in Sweden.
