There’s a simple error here I’m afraid.

The UK’s level of business taxation is already above the G7’s average.

You see, you cannot measure business taxation simply by what the marginal rate is. There are too many allowances (depreciation, R&D, training, huge numbers of them) and the tax base itself is different in different countries.

To actually measure the level (rather than the marginal rate) the best number to look at is the percentage of GDP raised in corporate profits taxation. For the G7 this is 3.5%. For the UK this is 4%.

So you’re actually arguing for a 12.5% cut in business taxation: a good idea, yes, but not one that provides any money to pay for your wages really.

Or it could be that I’ve entirely misunderstood you. Perhaps you believe that we’re on the wrong side of the Laffer Curve and that cutting marginal tax rates will increase revenues collected?
