HMRC has published this year's version of their <\/a>Tax Gap report. The supposed Tax Gap that they report is \u00a336 billion.<\/p>\n

This is the table of all the tax gaps reported since 2005\/06:<\/p>\n

\"screen-shot-2016-10-20-at-21-57-09\"<\/a><\/p>\n

The figure has never been higher than \u00a337 billion and never lower than \u00a332 billion. What is the chance of that? Especially when as the report notes of the methodologies used:<\/p>\n

\"screen-shot-2016-10-20-at-22-02-35\"<\/a><\/p>\n

Experimental is an interesting phrase: it in essence means 'we made it up'. If you don't believe me note this explanation:<\/p>\n

Experimental methodologies are used to produce illustrative estimates where there is no direct measurement data. Illustrative estimates are calculated using the best available data, simple models and assumptions.<\/p><\/blockquote>\n

Where assumptions means 'we guessed it'.<\/p>\n

And note even that the supposed established methodologies may not actually be used. In one of the areas you would have thought that HMRC would know most about, which is large business tax avoidance, this is the data (from their Excel tables):<\/p>\n

\"screen-shot-2016-10-20-at-22-05-57\"<\/a><\/p>\n

Let's ignore the obvious fact that the notes make clear that the second 2013-14 column is actually 2014-15 and instead note that for these key estimate they have done no work since 2012-13 and have rather optimistically assumed that the significant, and unexplained falls post 2011 continued, implying that in less than a decade tax avoidance in big business almost halved.<\/p>\n

Someone should tell Theresa May. She said at Conservative Party conference:<\/p>\n

Nobody, no individual tycoon and no single business, however rich, has succeeded on their own.<\/p>\n

So it doesn\u2019t matter to me who you are.<\/p>\n

If you\u2019re a tax-dodger, we\u2019re coming after you.<\/p>\n

If you\u2019re an accountant, a financial adviser or a middleman who helps people to avoid what they owe to society, we\u2019re coming after you too.<\/p>\n

An economy that works for everyone is one where everyone plays by the same rules.<\/p>\n

So whoever you are you \u2014 however rich or powerful \u2014 you have a duty to pay your tax.<\/p><\/blockquote>\n

But according to HMRC the problem is already almost solved.<\/p>\n

Except, that is, for one obvious little problem: which is that they have not actually bothered to go and find out.<\/p>\n

And that is typical of the their deeply misleading tax gap statistics which they trumpet as if it is an indication of their success when candidly they only looks like a crock of dubious data, at best.<\/p>\n","protected":false},"excerpt":{"rendered":"
