It is now clear that there are two different tax debates going on within the UK and a further European debate just to complicate matters.

Firstly there is the debate over the top rate of income tax.  The various press leaks and briefings show how important the UK coalition parties view this issue.  The Tories are laying the groundwork for its removal.  The Liberals are fighting a rearguard action.  Think of the Treasury Secretary’s “cloud cuckoo land comment.   The Liberals are also briefing on its own “mansion tax” policy.  If the top rate is abolished they want it replaced by a mansion tax.  The SNP and Labour are arguing for the top rate to be retained.

Then there is the devolution of tax powers to the Scottish Parliament.  My blog on this last Sunday can be found here.   The Scottish Government published its paper on corporation tax this week.   The paper can be found here.  As I said last Sunday, it is not what is being discused that I find most interesting but rather what is not being discussed.   I suspect that the real battle on this has still to start.

Then there is the European dimension and in particular the pressure being placed on Ireland by France and Germany over its low rate of corporation tax.   This issue also impacts on the UK tax debate as it poses the question: why is tax competition within the European Union a good thing but not within the UK?   As I said, an interesting week in tax land.
