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.

Is there such a thing as responsible betting?

Punters are encouraged to bet responsibly. What a laugh that is. It’s like encouraging drunks to get drunk responsibly, to crash our cars responsibly, murder each other responsibly.

I try not to watch the commercials between matches, or the studio discussions, or anything really, before or after, except for the match itself. And yet there is one person I never manage to escape properly – Ray Winstone. His cracked face, his mesmerising voice, his endlessly repeated spiel follow me across the room as I escape for the lav, the kitchen, the drinks cupboard.

I’m not sure which betting company he is shouting about, there are just so many of them, offering incredible odds and supposedly free bets. In the past six years, since the laws changed, TV betting adverts have increased by 600 per cent, all offering amazingly simple ways to lose money with just one tap on a smartphone.

The one I hate is the ad for BetVictor. The man who has been fronting it, appearing at windows or on roofs, who I assume is Victor, is just so slimy and horrible.

Betting firms are the ultimate football parasites, second in wealth only to kit manufacturers. They have perfected the capitalist’s art of using OPM (Other People’s Money). They’re not directly involved in football – say, in training or managing – yet they make millions off the back of its popularity. Many of the firms are based offshore in Gibraltar.

Football betting is not new. In the Fifties, my job every week at five o’clock was to sit beside my father’s bed, where he lay paralysed with MS, and write down the football results as they were read out on Sports Report. I had not to breathe, make silly remarks or guess the score. By the inflection in the announcer’s voice you could tell if it was an away win.

Earlier in the week I had filled in his Treble Chance on the Littlewoods pools. The “treble” part was because you had three chances: three points if the game you picked was a score draw, two for a goalless draw and one point for a home or away win. You chose eight games and had to reach 24 points, or as near as possible, then you were in the money.

“Not a damn sausage,” my father would say every week, once I’d marked and handed him back his predictions. He never did win a sausage.

Football pools began in the 1920s, the main ones being Littlewoods and Vernons, both based in Liverpool. They gave employment to thousands of bright young women who checked the results and sang in company choirs in their spare time. Each firm spent millions on advertising. In 1935, Littlewoods flew an aeroplane over London with a banner saying: Littlewoods Above All!

Postwar, they blossomed again, taking in £50m a year. The nation stopped at five on a Saturday to hear the scores, whether they were interested in football or not, hoping to get rich. BBC Sports Report began in 1948 with John Webster reading the results. James Alexander Gordon took over in 1974 – a voice soon familiar throughout the land.

These past few decades, football pools have been left behind, old-fashioned, low-tech, replaced by online betting using smartphones. The betting industry has totally rebooted itself. You can bet while the match is still on, trying to predict who will get the next goal, the next corner, the next throw-in. I made the last one up, but in theory you can bet instantly, on anything, at any time.

The soft sell is interesting. With the old football pools, we knew it was a remote flutter, hoping to make some money. Today the ads imply that betting on football somehow enhances the experience, adds to the enjoyment, involves you in the game itself, hence they show lads all together, drinking and laughing and putting on bets.

At the same time, punters are encouraged to do it responsibly. What a laugh that is. It’s like encouraging drunks to get drunk responsibly, to crash our cars responsibly, murder each other responsibly. Responsibly and respect are now two of the most meaningless words in the football language. People have been gambling, in some form, since the beginning, watching two raindrops drip down inside the cave, lying around in Roman bathhouses playing games. All they’ve done is to change the technology. You have to respect that.
