As I have noted earlier today, the Mail put out an estimate of £159 million of tax avoided by Microsoft in the UK today. In my blog I noted this was not my calculation (the main story and number were published before I spoke to any journalist or knew the Sunday Times had also looked at this issue) and that I thought it looked high.
I now confirm I do think it looks high.
I have looked at Microsoft’s 10-K accounts for 2012 (available on link from here). The turnover to Jun 2012 was $73.7 bn and the profit pre tax was $22.26. That’s a margin of 30.2%.
Tax was declared of $5.289bn, of which £2.388bn was in the US, $1.947bn was international but not specified and $0.954bn was deferred.
Now it’s been reported that Microsoft has a UK estimated trade turnover of £1.7 billion but according to reports only £663 of this goes through Microsoft UK, the rest being billed from elsewhere. The suggestion is that Luxembourg is used.
If the UK sales are really £1.7 billion then the UK profit margin should be, assuming homogenous margins (and there is no reason not to, in my opinion) about £513 million.
Tax due on that would be about £122 million.
It has been reported that £19 million was paid.
That would seem to suggest tax saved of £103 million, and not £159 million, which looks like a journalists error.
If true, that scale of avoidance remains considerable and helps explain why Microsoft has an overall tax rate of less than 20% compared to the 35% (0r more) US tax rate. The 10-K implies the overseas rate was under 14% and admits it was low due to makinng sales throgh Ireland, Puerto Rico and Singapore, all clearly chosen for their low tax rates. But I think the record needs to be put straighter than what appears to be an over-estimate at £159 million.
