Freelance income from oversees clients/book advance counted as foreign income?

Hi there - I am a writer and freelance social media assistant. One of the clients I do freelance work for is based in the US, but she pays me directly and I pay no US tax on it. I've been trying to determine whether this counts as 'foreign income' or not. I've read several other similar forum posts on here but simply ended up more unsure; some answers seemed to suggest that yes, it does count as foreign income, but unless I paid US taxes on it and am wanting to claim back tax relief, then I don't need to complete the foreign income section of my return? Is that correct? Similarly: I also wrote a book, which has been published with different publishers in the US and the UK. I received an advance payment from my US publisher, but it was paid to me *via* my UK-based literary agent. I have the same questions here: Does this count as 'foreign income'? And do I need to fill out the foreign income section of the return? Thank you

Hi,
This would form part of your self employed turnover and not foreign income. you only need the foreign page for this type of income if tax has been deducted for you to claim relief.
Thank you.
