Tax File Number (TFN) Declaration Form – Fillable PDF

The Tax File Number (TFN) Declaration is a mandatory Australian tax form used by employers, banks, and government agencies to determine the correct amount of tax to withhold from payments. Our page provides a fillable PDF version of the official TFN Declaration, so you can complete it quickly and accurately.

What is the TFN Declaration?

The TFN Declaration collects essential information about the payee, including their TFN, residency status, and any tax offsets. The data is used for PAYG (Pay As You Go) withholding calculations and must be provided before the first payment is made.

How to Fill Out the TFN Declaration Form Online

Instead of downloading the PDF and opening it in a separate editor, simply click the "Fill out this form" button on this page. The Formize PDF Filler app will load in your browser, letting you type directly into each field, select check‑boxes, and save your changes.

Common Mistakes to Avoid

• Using a pen or stylus on the downloaded PDF – the online filler eliminates this risk.
• Leaving the "Residency status" box blank – the ATO requires a clear selection.
• Entering an incorrect TFN format – double‑check the 9‑digit number.
• Forgetting to sign the declaration – the digital signature field is required.

Where to Submit the Completed Form

Once you have filled and saved the form, you can either:

• Download the completed PDF and email it to your employer or financial institution.
• Print the form and hand‑deliver it to the requesting party.

All submissions must be made before the first payment to ensure correct tax withholding.
