Working in Australia

Starting or changing work in Australia often raises practical questions about TFNs, payroll and the information an employer may request.

This section focuses specifically on the workplace side of the TFN system. It covers situations such as starting a first job, changing employers, taking a second job, completing employment-related tax information and understanding how a TFN fits into the payroll process.

The articles here are about working arrangements rather than immigration status. Visa-specific TFN questions are covered separately in the Visa Holders section.

Preguntas frecuentes

Do I need a new TFN when I start a new job?
Normally, you continue using your existing TFN when changing employers. Starting another job does not usually mean obtaining another number.
When does an employer ask for TFN information?
TFN information commonly becomes relevant when an employer sets up a worker for tax and payroll purposes. Current employer and employee requirements should be checked where the precise process matters.
What if I start work before I know my TFN?
The practical consequences depend on the circumstances and current tax rules. If you already have a TFN but cannot locate it, use TFN Help rather than submitting a new application.
Are visa work conditions covered here?
No. Questions specifically related to temporary visas, international students or visa-holder circumstances belong in the Visa Holders section.
