On your first day of work in Australia, two documents usually land in your hands together: the Super Choice Form and the TFN Declaration Form. The employer needs both before putting you on the payroll — and most people fill them in without really understanding what they're signing.

The form itself is simple: five questions. But two of them — the tax residency one and the tax-free threshold one — confuse immigrants like nothing else. Answering wrong isn't a crime, but it directly affects your net pay and the annual tax return reckoning.

This guide explains each question with the right answer for someone who arrived on a work or student visa. No legalese, no runaround.

What is the TFN Declaration Form?

It's the form you hand your employer with your tax file number (TFN) and information about your tax situation. Based on it, the employer calculates how much tax to withhold from your pay each payday.

The form — what it looks like

The TFN Declaration Form (NAT 3092) can be completed online via myGov or on paper. Below, the main fields of Section A — the part you fill in.

Tax file number declaration

What is your tax file number (TFN)?

Are you an Australian resident for tax purposes?

✅ Yes — most immigrants on a work or student visa

☐ No

3

5
Are you an Australian apprentice?

☐ Yes

The questions that matter most

Question 1: "What is your tax file number?"

Already received your TFN? Then just enter the number in the corresponding field.

Question 2: "Are you an Australian resident for tax purposes?"

Unsure about your specific situation? Check with the ATO or an accountant specialised in immigrants before signing.

Question 3: "Do you want to claim the tax-free threshold?"

First job and only job — answer YES

If this is your only job right now, answer YES. The first A$18,200 of your annual salary stays tax-free — meaning more net money in every pay.

Have two jobs? It's your choice — understand the consequences

If you already answered YES at another job, technically you should answer NO at the second one. But in practice you can answer YES at both — it's not prohibited. The consequence: the second employer withholds less tax, you take home more day to day, and the adjustment comes at the annual tax return.

The choice in a nutshell:

  • YES at both jobs → less tax now, more money each pay — but a bill may come at tax return time
  • NO at the second job → more tax now, less each pay — but the tax return closes settled or with a refund

It's a cash-flow decision. There's no wrong answer — as long as you know what you're doing.

Question 4: "Do you have an accumulated HELP debt?"

NO — unless you've taken out an Australian student loan (HECS/HELP), which isn't the case for the vast majority of immigrants.

Question 5: "Are you an Australian apprentice?"

NO — unless you're in a formal Australian Apprenticeship program. And no, an internship or trainee role from back home doesn't count.

HELP/HECS debt?❌ NO
Australian apprentice?❌ NO

What happens if you answer wrong?

It's not a crime — but it has financial consequences. Said YES to the tax-free threshold at two jobs? You'll owe tax at the tax return. Said NO while being a tax resident? You paid extra tax all year, but you get it back at the tax return. The annual reckoning (July to October) is when everything gets squared up.
