Apply for your client's TFN
You can apply for your client’s tax file number (TFN) when applying for their Australian business number (ABN).
You do not need to register them for a TFN in a separate process.
When you apply for a TFN at the same time you apply for an ABN, your client will be automatically registered with a business TFN when their ABN application is processed.
