The legislation for a super deduction disposal is provided under FA 20221 S12.
The person who incurred the super-deduction should be liable to any balancing charge in respect of any relevant event occurring S12(2). A relevant event would include a sale of the machinery. CAA 2001 S61. The company is liable to the balancing charge.
You need to establish the relevant proportion subject to the super deduction disposal. S12(3)
The expenditure needs to split between the value claimed in respect of relevant super-deduction expenditure and the total expenditure to find the relevant proportion S12(4)(5). In this situation, the whole amount of £400K would be the relevant proportion as the company originally claimed a super deduction on the entire £500K expenditure incurred in the relevant period.
The balancing charge calculation will depend on the timing of the disposal. The relevant factor is reduced for disposals occurring after 1 April 2023 to reflect the increase in corporation tax rates from 19% to 25%. The principle being that relief was given at 24.7% (130% @ 19%) and so the clawback should be commensurate.
On the 23 September 2022, the Chancellor at the time announced there would be a freeze on corporation tax rates at 19% from 1 April 23, therefore legislation would need to be changed for the relevant factor to be 1.3 on any super deduction disposal. However, on the 14 October 2022, the prime minister announced abolished the CT tax rates freeze. This means no legislation change will be required to FA21 S12 and relevant factors will be calculated as below.
If the chargeable period commences before 1 April 2023 and there are no dates in the chargeable period after 1 April 23, the relevant factor in the calculation is 1.3. FA 2021 S12 (6) (7).
Therefore, if your client sells this asset on the 30 September 22, the balancing charge calculation will be as follows:
If your client sells the asset on 30 June 2023, you will need to find the relevant factor between the days before the 1 April 23 and after that day. FA21 S12(8)
If the asset is sold on the 1 March 24, you would have no dates before the 1 April 23 meaning the disposal value would just be £400K as you would arrive at the relevant factor of 1.
If the Company had only claimed £300K as super deduction with £200K balance allocated to the main pool. To find the relevant proportion, you divide the £300K/£500K giving you 60% with that used against the disposal value of £400K=£240K. This amount would be then carried down for the relevant factor calculation. The 40% disposal balance would be allocated to the main pool. FA 2021 S12(3)(4)(5) (10)
