The decision was very likely inspired by news that Denmark will engage in similar experiment. The personal income tax rates have also traditionally been public in Finland on request. Transparency in corporate taxes is thus a logical step in promoting openness in taxes paid.
The data files are for year 2011 and include information on company level profits and corporate taxes levied. They are available as CSV data sheet and as two PDFs that span to more than 17 000 pages. The data files can be found on bottom of a web page, only in Finnish, here
