Income Tax

Harriett Baldwin Excerpts

Wednesday 28th November 2012 Commons Chamber

[Harriett Baldwin (West Worcestershire) (Con)]

It was a privilege to be present for the maiden speech of the hon. Member for Cardiff South and Penarth (Stephen Doughty), who spoke eloquently and passionately about his local area. The picture that he painted has made me eager to take the first possible opportunity to visit his constituency.

Let me begin with a small maths problem that I often pose to students in my constituency. If income tax rates were set at zero, how much income tax would the Chancellor raise? The students always get the answer right: it is zero. I then ask this question: if the Chancellor set the income tax rate at 100%, how much more income tax would he raise? Usually, someone will put his or her hand up and say, “He would raise a lot more.” I should welcome an intervention from any Opposition Member who has a view on how much income tax the Chancellor would raise if the rate was set at 100%.

[Sheila Gilmore]

Giving such an extreme and ridiculous example is unhelpful, as I think the hon. Lady is well aware. No Opposition Member is suggesting that the income tax rate should be 100%.

[Harriett Baldwin]

I seem to recall that in my lifetime—under the Government of, I think, the predecessor but one of the hon. Member for Cardiff South and Penarth—income tax was set at more than 90%. If it were set at 100%, we should have no income tax revenue, because no one would consider it worth while to work.

I then ask my students what would happen if we lowered the rate of income tax from 100% to 70%. Would we raise more or less revenue? Again, I should welcome interventions from Opposition Members. Everyone realises that we would raise more revenue, because if the rate was 70%, we would take home 30p in the pound. I notice that the new socialist Government across the channel recently introduced that income tax rate. We will see how that stacks up over time, but I expect that it will prove to be a deterrent to additional work, too.

The motion contains the seeds of its own mathematical inconsistency, because the Opposition are extrapolating a linear relationship between the income tax rate and the amount of income tax revenue raised. They are also extrapolating that those who can, in what is a global market, take their labour to any other country in the world will not take into account any difference in tax rates between the UK and other nations, yet all the evidence shows that that is not the case.

The Labour motion refers to 8,000 people paying income tax on income of £1 million or more. In 2009-10, which is the last tax year in which we had the 40p tax rate, some 16,000 people had an income of £1 million or more. Through raising the tax rate from 40p—a rate that was in place for all but one month of Labour’s entire 13 years in office—we can see that millionaires can do other things with their income. They can take their entire labour overseas, or they can decide to shelter their income or not to take a dividend that year, or they can use any of the other methods to ensure they do not pay that increase in income tax. There was a reduction of £7 billion in revenue after the income tax rate went up from 40p to 50p.

[Charlie Elphicke]

Will my hon. Friend give way?

[Harriett Baldwin]

I think that I have already taken two interventions, and I have only a minute and a half, unfortunately.

The Government have reduced the number of ways in which people on high incomes can reduce their taxable earnings. The Opposition opposed measures to reduce the amount people could put into their pension fund from more than £250,000 to £50,000. I also voted for the abolition of disguised remuneration, which was quite rampant under the previous Government. That also serves to limit the ways in which people on high incomes can reduce the amount of income tax that they pay.

The relationship between the rate of income tax and the amount of revenue raised by the Chancellor is non-linear. Between 0% and 100% there is a curve, and we need to agree about the optimal point on it—the point where the Treasury can get the most revenue from those at the highest end of the income spectrum. I suspect that 45p will be a lot closer to that optimal rate than 50p was.

The Government are focusing on tax cuts for those who are on the lowest incomes, lifting them out of income tax, and ending this tax cull on millionaires.

[Mr Deputy Speaker (Mr Nigel Evans)]

Order.
