You do not need to be in Australia to lodge. A return can be prepared and lodged from anywhere, for any year you earned Australian income, including years you have already left.
What actually gets harder once you have left?
Access, not the return itself. The tax position is identical whether you are in Brisbane or Berlin. What changes is that every verification step assumes an Australian phone number, an Australian address and an Australian identity document to hand.
A dead Australian SIM cannot receive verification codes, an ATO letter goes to a hostel that has forwarded nothing, and the call centre queue is an hour of hold music at 3am your time. None of these are tax problems, and all of them stop returns being lodged.
What do you actually need to have?
Less than most people assume. Employers report wages and withholding under Single Touch Payroll, so the income record already sits in ATO systems and lost payslips are rarely the obstacle they feel like.
- Your TFN, which is permanent and does not expire when you leave
- Passport details for identity verification
- An Australian bank account that is still open, for the refund
- Details of any ABN or contractor income, which carries no reporting behind it
- Receipts for any deductions you intend to claim
The bank account is the irreplaceable item. A refund the ATO cannot pay sits assessed but undelivered until an alternative is arranged from overseas, which is slower and more paperwork than leaving the account open a few more months.
When is the deadline, and does it move?
31 October following the end of the financial year for self lodgement. A return lodged with the ATO under a registered tax agent generally falls under a concessional date well into the following year, so an October deadline missed from another continent is rarely the problem it appears.
If you left partway through a financial year and are not returning, an early return covering a part year is sometimes possible before 30 June, which brings the refund forward.
How long does the refund take?
About 14 business days from lodgement in a straightforward case, paid in Australian dollars into an Australian account. A manual check by the ATO makes it considerably slower.
Overseas addresses attract more of those checks, particularly on a first return or where the TFN was recently issued. That is a delay rather than a refusal, and consistent identity details across passport, visa and TFN are what shorten it.
What about years you never lodged?
They are still lodgeable, and for departed working holiday makers that is often where the largest amounts sit. An unlodged year does not expire, and several can be lodged in one pass rather than sequentially.
This matters most for anyone who worked a first year, went home and never dealt with it. Those years usually contain a 45% period before the TFN landed and an unclaimed Medicare levy exemption, both still sitting there.
What if you end up owing rather than receiving?
Three situations turn a return into an amount payable: ABN income with nothing withheld, a declaration on which the tax free threshold was wrongly claimed, and a year of mostly cash work.
The ATO then issues a notice with a due date, and a payment plan can be arranged. The debt does not disappear because you have left the country, and it is not something to carry into a future Australian visa application. Our guide to ATO payment plans covers how those work.
Did you leave the right things in place?
Lodging from overseas is routine. How smooth it is depends on what you left in place, and each point below is harder to arrange after you fly.
- Whether an Australian bank account is still open to receive the refund.
- Whether the ATO holds a current address for you, rather than a hostel you left two years ago.
- Whether your identity details are consistent across passport, visa and TFN record.
- How many financial years are unlodged, since they can generally be dealt with together.
- Whether any of those years included ABN income, which changes a refund into a possible liability.
- Whether the super is also still sitting there, since departure is what makes a DASP claim available.
Each year is worked out separately in the working holiday tax return, and you can estimate your tax refund for each of them before deciding what to do.
