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.
Some are fairly minor, while others - such as the proposed simplification of capital gains tax - have been very controversial.
"This is the biggest set of changes to be implemented in any one year under Labour," said the Institute for Fiscal Studies (IFS).
These changes could be tweaked a bit by the chancellor on Wednesday, but this is how things stand at the minute. Budget changes - what is in the pipeline? >>>
