BBC: Even if Alistair Darling stood up on budget day, said nothing, and then sat down again, there would still be many changes to the taxation system this coming April.
More than 30 separate alterations were announced in last year's budget and also in last autumn's pre-budget report.
And nearly all will come into effect on 5 April.
