I've been offered a few days work as a sideline to my normal work (it has come to me through my company so no problem in that respect). I think they will be paying by bank transfer rather than PAYE. Does anyone know how the tax would work? From searching I've seen something that says if you earn less than £1000 like this then you don't have to declare it, but want to make sure that's right. I don't really want to do a tax return, and it would obviously be more enticing if I didn't have to pay tax on this extra money!
