The budget has come and gone, with Mr Hammond somewhat stymied by his predecessor's mess and the upcoming turmoil of Brexit.
The risk profile of self-employed is higher than of those in employer based work, yet Hammond is to reduce the offsets available, with the National Insurance realignment. Unless you are a backbencher ex-Chancellor now working for BlackRock, of course.
I've been playing with the entirely synthetic national household income as a way to get a sense of outgoings. We all get one of those customised HMRC profiles which shows personal contribution to the various direct taxation categories. I decided to reprofile it for the 'all UK household' case, driven from the Office of National Statistics figures.
In practice the ONS produce a quintile (fifths) breakout of UK incomes and although the middle quintile shows an income of £33,758, I decided that the 'All Households' blend, which includes the lowest and highest in the right proportions, would give a more useful figure.
On that basis I can also see that the 'all households' lifetime tax bill has risen between 1995-96 to 2015-16 from £447k to £826k. In 2000 it was £583k. I guess that is worth a separate plot at some point.

But my original objective was to get a sense of the 'All households' contribution into various tax categories, including the EU.
An interesting read. Welfare, Health, State Pensions, Education and National Debt interest make up 75% of the tax bill. And the EU contribution? Smaller than overseas aid(1.2%), at 1.1%.
Let's convert that into the 'All households' direct tax contribution. Of the £9,514 direct tax, around £105 goes to the EU. Welfare, Health, State Pensions, Education and National Debt contribution is £7,145.

So perhaps Mr Hammond was right to leave Brexit out of his budget speech, although the 19% reduction in US dollar foreign exchange rate still takes some explaining.
