2023-2024 Tax Year – the story so far


The story so far is Red Team 23 Green Team 4

It has been a busy few months for new tax legislation with the chaos that surrounded Kwasi Kwarteng’s ‘mini-Budget’ on 23 September 2022, followed by Jeremy Hunt’s ‘emergency statement’ on 17 October 2022. Then a further Autumn Statement on 17 November 2022 has led to the Budget itself being subsequently announced for 15 March 2023.

So four “Budgets” in six months or to put it another way, one more than the number of Prime Ministers in the same period!

Some of the tax measures announced in the Autumn Statement 2022, have already been legislated through an Autumn Finance Bill, which became  Finance Act 2023  and any further measures announced at the Budget itself will follow in a second 2023 Finance Act, which it is expected will also include those measures previously published for inclusion in Finance Bill 2023 in July 2022.

In case this all seems a little hard to follow we thought it would be worthwhile summarising some of the main changes we know about and that might affect our clients.

As we await the Chancellor’s Spring Budget on Wednesday 15th March, there are loud calls for the Government to reduce the planned Corporation Tax increase and continue with the capital allowance super deductions.  However, the Chancellor has downplayed the prospects of a major tax cutting budget.  We will inform clients of the key points from the Spring Budget as quickly as we can on 15th March.
