If you’re starting a new job in Australia, you’ll be required to complete the Tax File Number Declaration Form PDF (Editable) to ensure the correct amount of tax is withheld from your salary. This official document is issued by the Australian Taxation Office (ATO) and is commonly referred to as TFN Declaration Form NAT 3092.
In this guide, you’ll learn what the TFN declaration form is, who needs it, how to fill it out, and how to download and edit the PDF version correctly.
What Is the Tax File Number Declaration Form?
The Tax File Number (TFN) Declaration Form is used to:
- Provide your Tax File Number (TFN) to your employer
- Determine how much tax should be withheld from your income
- Claim the tax-free threshold
- Declare your tax residency status
- Notify your employer about education loan debts (HELP, SSL, TSL)
- Claim eligible tax offsets
Important: This is not a TFN application form. If you need to apply for a new TFN, you must do so separately through the ATO.
