Good afternoon, I would like to enquire whether foreign earnings from self-employment as a sole trader are considered foreign income. If so, do I have to complete the foreign section? All of my earnings stem solely from online services I offer and not from any land, property, or pensions. However, I am uncertain if I am understanding this correctly. I am an EU-citizen if this is of any relevance for this matter. I would greatly appreciate any assistance. Thank you.
