How to update Tax File Number Declaration details and tax selections

To update the tax selections on your TFN, we will need to issue you with a new TFN form. Send us a quick email at supportaus@oncoreservices requesting a new TFN be emailed to you. We will issue this via an e-signing platform for easy completion of a new form. Once we've received the new fully completed TFN form, please allow up to 24 hours for your tax selections to be updated in our system for payroll.
