No idea whether this is a continuation of somthing Labour did - doesn't make it OK if it is per se, as Labour did a hell of a lot of crap too.
So far, no-one has actually refuted on the crux of the matter as stated here:
"At the moment tax law ensures that companies based here, with branches in other countries, don't get taxed twice on the same money. They have to pay only the difference between our rate and that of the other country. If, for example, Dirty Oil plc pays 10% corporation tax on its profits in Oblivia, then shifts the money over here, it should pay a further 18% in the UK, to match our rate of 28%. But under the new proposals, companies will pay nothing at all in this country on money made by their foreign branches.
Foreign means anywhere. If these proposals go ahead, the UK will be only the second country in the world to allow money that has passed through tax havens to remain untaxed when it gets here. The other is Switzerland. The exemption applies solely to "large and medium companies": it is not available for smaller firms. The government says it expects "large financial services companies to make the greatest use of the exemption regime". The main beneficiaries, in other words, will be the banks.
But that's not the end of it. While big business will be exempt from tax on its foreign branch earnings, it will, amazingly, still be able to claim the expense of funding its foreign branches against tax it pays in the UK. No other country does this. The new measures will, as we already know, accompany a rapid reduction in the official rate of corporation tax: from 28% to 24% by 2014. This, a Treasury minister has boasted, will be the lowest rate "of any major western economy". By the time this government is done, we'll be lucky if the banks and corporations pay anything at all. In the Sunday Telegraph, David Cameron said: "What I want is tax revenue from the banks into the exchequer, so we can help rebuild this economy." He's doing just the opposite.
These measures will drain not only wealth but also jobs from the UK. The new legislation will create a powerful incentive to shift business out of this country and into nations with lower corporate tax rates. Any UK business that doesn't outsource its staff or funnel its earnings through a tax haven will find itself with an extra competitive disadvantage. "
Sorry to repeat it, but it seems people have been basing recent posts on an anymous contribution from a mumsnetter a page or two back, which provides no proof at all and just makes vague assertions that everything's going to be just fine.
I have yet to see proof of this.
