Short term income from one off opportunity.

I did some part time, short term work for a company this year April 2023 - October 2023. It was 57 days work and was a one off. When does the tax due for this need to be completed and how do I do that ?

Hi taxdb,
As this is the 23/24 tax year, this will be self employment income to be notified to HMRC by 31/01/25 on a self assessment tax return.
Thank you.
