The Special rate allowance due on expenditure incurred in the period 1/4/2021 to 31/3/2023 is 50% of the cost. The remaining 50% is added to the Special rate pool written down value carried forward. A written down allowance can then be claimed in next period.

This section on the calculation tab will only be shown where the return period covers the period on which allowances can be claimed and where assets on which a Special rate allowance was previously claimed has not been disposed.

Expenditure


AIA limits

This section shows the maximum AIA that can be claimed in this period.

If you have used the Asset movements tab to enter the expenditure in the period then this area will show all the expenditure in the period that is applicable for AIA. Where possible a suggested allocation will also be shown. This allocation assumes that 100% FYA is claimed for all assets that are eligible, and then prioritises expenditure that would otherwise only attract the lower special rate of writing down allowances.

If you want to apply the suggested AIA allocation across all asset types then select Apply suggested AIA allocation. (If the option is not shown then the suggested AIA allocation has already been applied).
