I'm a New Zealand citizen/resident working from New Zealand as a sole trader. I do freelance work and one of my clients is an Australian business. I make about 40K a year, do I have to happy for an ABN?
If it makes any difference, the Australian business I work for is a mobile tutoring company, so no fixed premises. I offer services only (admin & customer service) and the business provides both services and goods (ebooks) to its customers.
Finally, I do have a TFN and Australian bank account from when I lived in Australia 10 years ago. If I was paid into my Australian bank account would that change my tax obligations or requirements?
