If you need to change your return

Thank you.

Hi again, I have to now adjust my 2022 to 2023 tax return, I didn't realise that I could claim 100% for my driving instructor car, fitted with dual controls, I have completed the 2022 to 2023 cash basis tax return. My question is, I now know I can claim the annual investment allowance for my instructor vehicle. Do I need to include the cost of the instructor vehicle within the total value for expenses or will the system take it into account once I've entered the value into the AIA section, or will I now have to complete a detailed breakdown of my expenses. Thanks in advance.

Hi,

The cost is inlcuded and entered under the AIA section and should not be included in the expenses section.

Thank you.

Good Morning, I have a question about AIA and the options open to me in the 2023 - 2024 tax year self assessment. I am completing my self assessment using the cash basis. I claimed for my instructor car fitted with dual controls within my 2022 - 2023 self assessment, this claim made me a loss of just over £5,000 in 2022 - 2023, can I claim this loss within my 2023 - 2024 self assessment, or am I restricted due to the cash basis type of account I carry out.

Hi Kendo65,
You will need to amend your 22/23 tax return to request the loss is carried forward, you have until 31 January 2025 to do this.  
The loss can be carried forward and set against the profit of a future tax year.  
The cash basis of accounting allows you to carry the loss forward, but not set it against other income arising in the tax year the loss occurs.  
Please also have a look a the guidance at Cash basis Cash basis changes from the 2024 to 2025 tax year for changes that will come into effect next year.
Thank you.
