Income source on work visa
So, I am on a work visa which is tied to my job, and have recently sent off the residency application (the ITA). Now, I have recently taken on more tasks at work, and turns out the extra work is to be paid cash and I have to arrange to pay the tax on it myself, in comparison to my normal workload which is on a normal contract and I get paid per fortnight. The extra work is the same as my work visa is for, but payment is in a different form... The question here is if I can take cash for work, and pay the tax on it as I go along, or if I need to make changes to my visa for this? The question has come up if I am able to invoice customers, which I am obviously not... However, I have been told it would be preferable if I could. It's a bit of a nightmare, and I would like not to turn down extra work, but if I can't do this on my visa, then I won't. Anyone got any advice?
