Complete your TFN Declaration (NAT 3092) online and download a filled PDF instantly. Required when starting a new job in Australia.
When do you need this form?
When you start a new job or take on a second job, your employer needs this form to know how much tax to withhold from your pay. You also need to fill it in if your circumstances change — for example, if you want to start or stop claiming the tax-free threshold.
What you'll need
- Your Tax File Number (TFN) — find it on your myGov account, a previous tax return, or a letter from the ATO
- Your residency status for tax purposes
- Whether you want to claim the tax-free threshold from this employer
Where to send it
Give the completed form to your employer — do not send it to the ATO. Your employer must forward it to the ATO within 14 days of receiving it.
