The tax changes announced in the Budget were a broadly self financing package, with over £2bn per annum of giveaways on largely freezing fuel and alcohol duty, reducing stamp duty on first time buyers, and more help on business rates.

All this is pretty well financed by more anti-avoidance and tougher compliance measures, by stopping indexation allowance on corporate capital gains, freezing the VAT threshold, and extending non-resident capital gains to commercial property.

There was also an extra £175m per annum on the research and development credit increase, but that now counts as a spending rather than a tax decision.

But the government’s figures show the overall tax take being reduced by £1.4bn per annum. This is because there has been no attempt to recover the cost of previously announced climb downs on the ill-fated Spring Budget NICs proposals, on Making Tax Digital, and on tuition fees.
