In principle, the Spring Statement is not expected to introduce any changes to tax policy, particularly since many of the measures announced in the Autumn Budget have yet to be implemented.
That being said, there is feeling amongst many that the Spring Statement could become a mini-Budget. This is largely down to the fact that since the Budget announcement, economic growth has been slower than hoped for and government borrowings have increased. Resurgent inflation could also lead to increasing wage demands.
This means that at some point soon, the Chancellor will have to decide between further tax increases or cuts to spending.
