Getting an ABN (Australian Business Number)

Do I need an ABN?

When completing a task, a Task Poster may request the person completing the task (the Airtasker) to provide an ABN.

An ABN is an Australian Business Number, which businesses and independent contractors use when dealing with the Australian Tax Office (ATO) or other government departments.  If the Task Poster is asking you to get an ABN, it is possible that he or she is hiring you as an independent contractor.

Many tasks on Airtasker are done on an independent contractor basis. If you’re not familiar with what it means to do work as an independent contractor, we suggest doing some research to learn more. Being independently employed means having the freedom to do different kinds of work for lots of different people, and that involves managing your time, obligations, and income on your own.

Whilst not an absolute rule, you are generally considered an independent contractor if you decide how and when you want to complete a task and if you use your own tools rather than the equipment of the Task Poster.

Remember: Airtasker is an open marketplace for people to outsource tasks, find local services or complete flexible jobs to earn money.  Our users have the freedom to work with people or businesses in the structure that suits the individual circumstances of the task or job – whether as an independent contractor or as an employee.  If you’re not sure whether the Task Poster is assigning you to a task as an independent contractor or as an employee, it’s always best to ask them.
