I am self employed and worked as a contractor whilst living overseas for 2 months. I did not pay tax on my remuneration which was in Euros. Do I file this income under " Any other overseas income and gains" in the Foreign income details (Page 2 of 2) section? The option "Employment, self-employment and other income which you paid foreign tax on" Does not work as I have not paid foreign tax

Do you have to register as a sole trader if you are simply earning a one off income? e.g Payment for a Guest lecture or Speech?
