You're hinting at a reform of the French administration ? Vade retro satanas ! <s>

A project to merge the tax calculation and the tax perception services faced harsh opposition a few years ago. Indeed, you send your declaration paperwork and receive a notification of how much you owe from one administration, but the check has to be sent to another administration.
If the latter mislay your post (which often happens) or worse, forget to debit your account, you receive a letter from the former notifying a penalty payment. And have to prove it's not your fault that their fellow civil servants did wrong. Delightful ...

When through hell, just keep going. W. Churchill
