I'm considering starting my own little business as an IT Trainer. I've not worked for many a year. I was under the impression that there wouldn't be a huge market for this sort of thing but having volunteered for a charity for a while I have discovered that there are many people who would like some help to improve their IT skills.
I was thinking of advertising on some local Facebook groups to see whether there is any interest in my area.
My question is, if this turns out to be viable, would I need to register a company for tax purposes. I see so many small businesses advertised on local Facebook pages but have no idea whether any of them pay tax.
