Hello MickT,
Welcome to the Community - thank you for your question!
This will depend on the category you select, you will need to check this with either HMRC or an accountant on what category would be best to make sure you are not taxed on this (unfortunately as we are not accountant trained, we would not be able to advise which category will be best, as we would not want to give you any incorrect advice).
Thanks,
Talia
