Why is tax avoidance a reason for letting people off tax?

Tax dodging, the Laffer curve, and the 50p rate

The reason given for cutting the 50p rate of tax to 45p was avoidance. It wasn't clearly phrased as such – most of the talk was about how it had raised less money than expected, or had changed behaviour in ways that harmed growth – but that is what it was nonetheless. To many, this will seem strange. "You avoided tax, so we will make you pay less". But it is an integral part of the line of thought that lies behind the cut.

Art Laffer first made the argument that cutting tax rates could boost revenue. The reasoning is broadly that, when the marginal tax rate (the amount you pay on each extra pound earned) gets too high, people start doing things to reduce their taxable income.

The palatable version is that they work less, because an extra hour of work no longer pays as well as it did, and this is probably true; there are certainly anecdotal tales of highly paid consultants turning down work later on in the year to spend more time at home.

The less palatable version is that they avoid more tax, because spending the money and effort required to set up a limited company, be paid "overseas", or funnel your income through a Swiss bank account in the name of your dog becomes more worthwhile the more it saves you.

Both of these "behavioural changes" are factored in to the Laffer curve, the rough prediction of how much revenue will be gained at various marginal tax rates. HMRC produced three such curves, each based around a different "taxable income elasticity" (TIE), a measure of how much an individual's behaviour changes given the tax rate:

They based their analysis around a TIE of 0.45 (a figure basically plucked from thin air – HMRC admit the evidence to choose is "extremely limited", and the studies they cite range from -0.6 to 2.75), which showed a peak of revenue at around 48 per cent. Quite why this then led the Chancellor to cut the rate to three per cent below that is unclear. If he wanted to raise revenue, his own analysis is showing that he's done it wrong.

The problem is, one thing which affects the TIE is the ease with which one can avoid tax. Make tax avoidance harder, TIE goes up, and the peak revenue rate increases. In fact, given the anti-avoidance measures announced at the budget yesterday, TIE will already be higher than it was at the time of the analysis, boosting the argument for keeping the 50p rate.

There is one massive category of avoidance which can't be cited as a reason for cutting the rate, however. The HMRC's stats show that £6.6bn less income was declared in 2010-11 due to it being "forestalled" – paid the year before, so as to take advantage of the lower rate. This is avoidance on a massive scale (Richard Murphy points out that it is £1.6bn more than the estimation for all tax avoidance in 2011), yet, contra Tim Worstall, it has no bearing on the decision on whether or not to cut the rate, because it can only ever be done once. 

By cutting the tax so early in its life, Osborne has ensured that we make the decision unable to know the full effect of cutting it. We can guess at how much will have been raised for the 2011-12 tax year, when forestalling was harder (although not impossible, and HMRC warn that it "continues to reduce revenues in 2011-12 and beyond"), but by the time we know for sure, it will be too late. The 45p tax will be in, and there won't be a "normal" year of the 50p rate to compare it to.

A new German law wants to force mothers to reveal their child’s biological father

The so-called “milkmen’s kids law” would seek protection for men who feel they have been duped into raising children they believe are not biologically theirs – at the expense of women’s rights.

The German press call them “Kuckuckskinder”, which translates literally as “cuckoo children” – parasite offspring being raised by an unsuspecting innocent, alien creatures growing fat at the expense of the host species’ own kind. The British press have opted for the more Benny Hill-esque “milkmen’s kids”, prompting images of bored Seventies housewives answering the door in negligées before inviting Robin Asquith lookalikes up to their suburban boudoirs. Nine months later their henpecked husbands are presented with bawling brats and the poor sods remain none the wiser.

Neither image is particularly flattering to the children involved, but then who cares about them? This is a story about men, women and the redressing of a legal – or is it biological? – injustice. The children are incidental.

This week German Justice Minister Heiko Maas introduced a proposal aimed at to providing greater legal protection for “Scheinväter” – men who are duped into raising children whom they falsely believe to be biologically theirs. This is in response to a 2015 case in which Germany’s highest court ruled that a woman who had told her ex-husband that her child may have been conceived with another man could not be compelled to name the latter. This would, the court decided, be an infringement of the woman’s right to privacy. Nonetheless, the decision was seen to highlight the need for further legislation to clarify and strengthen the position of the Scheinvater.

Maas’ proposal, announced on Monday, examines the problem carefully and sensitively before merrily throwing a woman’s right to privacy out of the window. It would compel a woman to name every man she had sexual intercourse with during the time when her child may have been conceived. She would only have the right to remain silent in cases should there be serious reasons for her not to name the biological father (it would be for the court to decide whether a woman’s reasons were serious enough). It is not yet clear what form of punishment a woman would face were she not to name names (I’m thinking a scarlet letter would be in keeping with the classy, retro “man who was present at the moment of conception” wording). In cases where it did transpire that another man was a child’s biological father, he would be obliged to pay compensation to the man “duped” into supporting the child for up to two years.

It is not clear what happens thereafter. Perhaps the two men shake hands, pat each other on the back, maybe even share a beer or two. It is, after all, a kind of gentlemen’s agreement, a transaction which takes place over the heads of both mother and child once the latter’s paternity has been established. The “true” father compensates the “false” one for having maintained his property in his absence. In some cases there may be bitterness and resentment but perhaps in others one will witness a kind of honourable partnership. You can’t trust women, but DNA tests, money and your fellow man won’t let you down.

Even if it achieves nothing else, this proposal brings us right back to the heart of what patriarchy is all about: paternity and ownership. In April this year a German court ruled that men cannot be forced to take paternity tests by children who suspect them of being their fathers. It has to be their decision. Women, meanwhile, can only access abortion on demand in the first trimester of pregnancy, and even then counselling is mandatory (thereafter the approval of two doctors is required, similar to in the UK). One class of people can be forced to gestate and give birth; another can’t even be forced to take a DNA test. One class of people can be compelled to name any man whose sperm may have ventured beyond their cervix; another is allowed to have a body whose business is entirely its own. And yes, one can argue that forcing men to pay money for the raising of children evens up the score. Men have always argued that, but they’re wrong.

Individual men (sometimes) pay for the raising of individual children because the system we call patriarchy has chosen to make fatherhood about individual ownership. Women have little choice but to go along with this as long as men exploit our labour, restrict our access to material resources and threaten us with violence. We live in a world in which it is almost universally assumed that women “owe” individual men the reassurance that it was their precious sperm that impregnated us, lest we put ourselves and our offspring at risk of poverty and isolation. Rarely do any of us dare to protest. We pretend it is a fair deal, even that reproductive differences barely affect our lives at all. But the sex binary – the fact that sperm is not egg and egg is not sperm – affects all of us.

The original 2015 ruling got it right. The male demand for reassurance regarding paternity is an infringement of a woman’s right to privacy. Moreover, it is important to see this in the context of all the other ways in which men have sought to limit women’s sexual activity, freedom of movement and financial independence in order to ensure that children are truly “theirs”.  Anxiety over paternity is fundamentally linked to anxiety over female sexuality and women’s access to public space. Yet unless all women are kept under lock and key at all times, men will never, ever have the reassurance they crave. Even then, the abstract knowledge that you are the only person to have had the opportunity to impregnate a particular woman cannot rival the physical knowledge of gestation.

We have had millennia of pandering to men’s existential anxieties and treating all matters related to human reproduction, from sex to childbirth, as exceptional cases meaning women cannot have full human rights. Isn’t it about time we tried something new? How about understanding fatherhood not as winning gold in an Olympic sperm race, but as a contract endlessly renewed?

What each of us receives when a child is born is not a biological entity to do with as we choose. It is a relationship, with all of its complexities and risks. It is something worth contributing to and fighting for. Truly, if a man cannot understand that, then any money wasted on a Kuckuckskind – a living, breathing child he could get to know – has got to be the least of his worries.
