Hi Sam
As a contractor working for the same person for two years or more under work cover laws your deemed to be an employee and they require your personal tax return if you have a work cover issue. I was on $55per hr then had a claim where I tore my Knee and under work cover I was paid $12 per because I took a small wage from my company, I was screwed because my knee would not heal and I could not get off the work cover merry go round it sent me broke. As a contractor you have to work 20 % or some one else or other jobs to not be deemed as an employee.
If your builder has you on 30 day and goes broke you can get caught in the domino effect.
If your good and can get your own work and keep up with the paperwork then there’s big money to be made but all work and no play makes Sam controlled by his business, it can be a trap it all about the ability to say NO sometimes.
Go for it
