The short version
If you have a HECS-HELP balance and intend to live outside Australia for 6 months or more in a 12-month period, you must:
- Notify the ATO via myGov (Overseas Travel Notification) within 7 days of your departure.
- Declare your worldwide income each Australian tax year, whether or not you earn anything in Australia.
- Make compulsory repayments if your worldwide repayment income exceeds the threshold ($67,000 for FY2025-26 under the new marginal system).
Failure to comply can result in failure-to-lodge penalties ($330 per 28 days, capped), administrative penalties for false declaration, and ultimately referral to debt collection.
What counts as worldwide income
All income earned from any source, in any currency, converted to AUD using the ATO's prescribed conversion rates. This includes salary in foreign currency, self-employment income, rental income, investment returns, and distributions from overseas trusts. Tax paid in the foreign country does not reduce your Australian repayment income — it may reduce your overall Australian tax bill under double tax treaties, but HECS is calculated on gross repayment income.
How to make payments from overseas
Three options:
- BPAY from an Australian bank account — simplest if you've kept one open.
- International wire transfer — use the SWIFT/BSB details from your ATO account. Allow 5–10 business days.
- Credit card via ATO portal — 1.45% surcharge applies but useful for one-off payments.
If you're making a voluntary payment before 1 June indexation, start the transfer by 22 May to account for international banking delays.
Common overseas tax situations
- Living in the UK — UK income is converted to AUD. UK tax paid reduces Australian income tax via the double tax treaty, but HECS is calculated on gross AUD income before UK tax.
- Living in a tax-free jurisdiction (UAE, BVI, etc.) — full worldwide income is declared. No foreign tax credit, so HECS repayment is calculated on your full gross earnings.
- Digital nomad — you're still an Australian tax resident unless you've established tax residency elsewhere. Worldwide income rules apply regardless.
- Non-resident for Australian tax purposes — your HELP obligation doesn't go away. You must still declare worldwide income for HELP repayment purposes even if you're not otherwise required to lodge an Australian tax return.
Common traps
- Not lodging the Overseas Travel Notification. The ATO imposes failure-to-lodge penalties and accrues them while you're absent.
- Assuming non-residency means no HELP obligations. Worldwide income declaration is required even for non-residents with HELP balances.
- Paying foreign tax and assuming HECS is reduced. HECS is calculated on gross repayment income — foreign tax reduces Australian income tax, not HELP.
