Last week, the UK Government announced that public sector buyers should start taking into account the track record of potential suppliers in terms of tax avoidance when they make supplier selection decisions. That is perhaps not quite as dramatic as it first sounds. There has been the ability under EU procurement regulations for many years to exclude firms who have evaded tax, just as you can rule out firms who are bankrupt or whose directors have criminal records (in some cases at least). But this new announcement has pushed the issue up the agenda considerably.
