DH was made redundant 6 months ago. His industry was badly hit by covid and he's been unable to find permanent work. Recently he was offered 4 weeks work by a old colleague which he accepted, starting last week. Contact told him to just "invoice" him. We've never done this before- how does it work and what's the best approach? Should he set up a ltd company (seems excessive fir what might only be one months work)? If he just invoiced the chap and reported it later on his tax return is that ok?
He's employed full time in the role....
