Sharing your Tax File Number is important because if you haven’t provided us with a TFN or TFN exemption, we’re required to deduct tax from any interest we pay to you at the highest marginal tax rate. 

You can view and update your Tax File Number (TFN) and exemption in the Suncorp Bank App:

1. Log in to the Suncorp Bank App.
2. Tap 'More' in the menu bar, then select 'Profile'
3. Tap 'Tax File Number (TFN)' and follow the prompts.
