Tax File Number Declaration Form – Fillable PDF for New Employees

Starting a new job in Australia? Your employer will ask you to complete a Tax File Number (TFN) Declaration before you receive your first payment. This form confirms your TFN, residency status, and whether you want to claim the tax‑free threshold.

Why You Need the TFN Declaration Form

The TFN Declaration is a legal requirement under the Australian Taxation Office (ATO). It helps your employer with the correct amount of tax to withhold and ensures you receive any applicable tax offsets.

How to Fill Out the Form Using Formize

Instead of downloading the PDF and hunting for a PDF editor, simply click the "Fill out this form" button on this page. The Formize PDF Filler app will load instantly, letting you type directly into each field.

Common Mistakes to Avoid

• Leaving the TFN blank: Your employer cannot process payroll without it.
• Selecting the wrong residency option: Choose "Australian resident for tax purposes" unless you are a foreign resident or working holiday maker.
• Claiming the tax‑free threshold from more than one employer: This can lead to a tax bill at the end of the year.

Where to Submit the Completed Form

Give the printed or digitally signed form to your HR or payroll department. They will keep it on file and use the information for your PAYG withholding.
