Employees working abroad: Australian employer duties
Reviewed by Mellow Editorial Team, HR & payroll content team
Australian employers remain responsible for payroll, tax and compliance obligations even when an employee works outside Australia — the extent of those obligations depends on where the employee works, for how long, and whether a tax treaty applies.
What triggers your obligations
The starting point is the employment contract. If the employee remains on your Australian payroll, you generally continue to withhold PAYG income tax, report through Single Touch Payroll, and pay the Superannuation Guarantee — currently 12% of ordinary time earnings — into a complying Australian fund.
The complication is that the host country may also assert tax jurisdiction over the employee, particularly once they become a tax resident there. Most countries apply a residency test based on days present, so a short-term work trip looks very different from a 12-month secondment.
Tax residency and PAYG withholding
Australian tax residency is not a simple on/off switch. The ATO applies several residency tests — the ordinary residence test, the domicile test, and the 183-day test — and an employee can remain an Australian tax resident even while working abroad for an extended period. If they do, PAYG withholding on their Australian-sourced income continues as normal.
If the employee ceases to be an Australian tax resident, your PAYG obligation on their foreign-sourced earnings generally falls away. You would typically notify the ATO, adjust the employee's tax file number declaration status, and cease withholding on those earnings. However, if any part of the remuneration relates to Australian duties — for example, equity that vested while they worked in Australia — those amounts can still be subject to Australian tax.
Where Australia has a tax treaty with the host country (there are treaties with most major economies), the treaty may determine which country has primary taxing rights. Tax treaties do not eliminate your administrative obligations automatically; they allocate liability, and you still need to understand the outcome before adjusting withholding.
HECS/HELP repayments are also relevant. If the employee has a study debt and remains an Australian tax resident, repayment obligations continue. If they have become a foreign resident, the ATO now requires overseas debtors to make voluntary repayments directly — but this is the employee's responsibility rather than yours.
Superannuation Guarantee obligations abroad
Super obligations follow the employment contract more closely than tax does. If an employee is hired under an Australian contract and paid by an Australian entity, the Superannuation Guarantee generally still applies, regardless of where the work is performed. You pay 12% of ordinary time earnings into their complying Australian fund, and you report and remit on the standard quarterly schedule.
There are limited exceptions. Some of Australia's bilateral social security agreements — sometimes called totalisation agreements — allow an employee on a genuine temporary assignment to be covered solely by the host country's pension system, exempting you from the Australian SG. These agreements exist with a smaller set of countries than the tax treaty network, so check the specific agreement (or its absence) before assuming an exemption applies.
Portability rules also matter for longer-term moves. If an employee permanently emigrates, they may eventually be able to access their super under the departing Australia superannuation payment (DASP) rules, but that is administered by their fund, not by you as the employer.
Single Touch Payroll and year-end reporting
STP reporting continues for every employee on your Australian payroll, including those working abroad. Each pay event must be reported at the time it is paid. At the end of the income year, you finalise the employee's payment summary information through your STP-enabled payroll system by 14 July.
If the employee has ceased Australian tax residency mid-year, it is good practice to note their residency status change in their payroll record and keep documentation — correspondence with the employee, advice from a tax adviser — that supports how you adjusted withholding. The ATO can review these decisions, and clear records protect you in that event.
Permanent establishment risk
This is a corporate tax issue rather than a payroll one, but it sits alongside your HR decisions. If an employee working abroad has authority to conclude contracts on your behalf, or operates from a fixed place of business, the host country may treat your business as having a taxable presence — a permanent establishment — there. That would create a corporate tax filing obligation in that country, separate from the employee's personal tax position.
HR and payroll teams are not expected to resolve this independently, but flagging the risk to your finance or legal team early — before the overseas arrangement becomes entrenched — avoids a harder conversation later.
Practical steps before the arrangement starts
Before an employee begins working abroad, work through these questions: Will they remain on the Australian payroll? How long is the assignment? What country are they going to, and does Australia have a tax treaty or totalisation agreement with it? Will they remain an Australian tax resident? What is their HECS/HELP position?
Getting clear answers — usually with input from a tax adviser familiar with both jurisdictions — lets you set up payroll correctly from day one rather than retrospectively unravelling months of incorrect withholding. For businesses managing employees across multiple countries, a consistent process for these questions becomes part of standard onboarding for any cross-border move. You can see how Mellow runs payroll across six countries on one platform as one example of how that process can be structured.
