I've been s/e for years but this year I've added a 'side line' to what I do (it's a craft.) I've invested a lot in tools, a website and stock, but so far have sold very little. Question is, on the HMRC online form, it asks for the type of work. I have always entered my main work, (which has two strings to it, X and Y) so what happens now with the craft stuff? Is that another return? or do I just add what I've spent onto outgoing and sales onto income? Or not bother because sales add up to about £50 and outgoings around £1K.
