I think I need some advice before I get myself into any trouble. I'm 21 and just recently started working in a gym. I get payed in cash from my private clients, and am payed via cheque by the gym owner. I am employed as a contractor/sole trader I believe. I don't believe I earned enough to be taxed for this financial year, but I need to get myself sorted for next year. I want to avoid doing anything dodgy/illegal, or atleast understand what would be considered illegal. This is my first 'real' job, so the whole process is unfamiliar to me. What would be the wise thing to do in my situation? How soon do I need to find an accountant in order to get myself organised financially? What services would I require an accountant for? Any recommendations? (I live in Melbourne) Because I would also like to start investing, I really think I might need some professional guidance/assistance. Thanks.
