Payroll and Superannuation for International Businesses
You're hiring Australian employees. The work is happening. The invoices are going out, and it all feels like it’s moving in the right direction until someone mentions superannuation. You realise you're not entirely sure what you're obligated to do, when you need to do it, or what happens if you get it wrong.
This is a common stumbling block for international businesses managing Australian staff from overseas. Australia may operate differently from the payroll systems in your country, and the Australian Tax Office's (ATO) timing and compliance expectations are strict.
Here's what you need to know.
What is Australian superannuation and who does it apply to?
Superannuation is Australia's compulsory retirement savings system. As an employer, you are required to contribute a percentage of each eligible employee's Qualifying Earnings (QE) into a complying superannuation fund on their behalf. It applies regardless of where your business is headquartered.
The current superannuation guarantee rate is 12% at the time of writing. You should verify the current rate with your accountant or via the ATO website.
Who must you contribute for?
In most cases, if you have any employee aged 18 years or older, you pay super regardless of how many hours they work. Casual employees, part-time employees, and some contractors may also be eligible, depending on the nature of the arrangement. If you're unsure whether a particular worker qualifies, confirm before assuming they don't. You can learn more on the ATO website.
When must you contribute?
Contributions must be made every payday and received by the fund within 7 business days. Missing a payment deadline triggers the Superannuation Guarantee Charge (SGC). It is ATO-assessed, and interest compounds daily at the general interest charge rate, with an administrative uplift that varies based on your compliance history. Penalties range from 25% to 50% of the unpaid SGC, depending on prior penalties, so building super processing into every pay run from the start is essential.
Employees are generally entitled to choose their own superannuation fund. If they don't make a choice, you're required to contribute to a default fund that meets certain criteria, or to the fund nominated under the stapled super fund rules. This requires you to check with the ATO for an employee's existing fund before defaulting to your own. This is an important step that international businesses often miss.
Setting up payroll in Australia
Australian payroll runs through a framework called Single Touch Payroll (STP). Under STP, employers digitally report wages, tax withheld, and superannuation information to the ATO each time a pay run is processed. This reporting can only be done through STP-enabled payroll software.
Cloud-based platforms such as Xero and MYOB are widely used in Australia and integrate directly with the ATO's STP framework. If your international business or group uses a global payroll or ERP system, check whether it has Australian STP compliance built in, or whether Australian payroll needs to run through a local system alongside it. Many international businesses find it cleaner to manage Australian payroll locally, with reporting fed back to the group finance team.
Before payroll can be processed, each employee needs a Tax File Number (TFN). A TFN is the Australian equivalent of a tax identification number, and employees apply for it through the ATO. If an employee hasn't provided their TFN, you're required to withhold tax at the highest marginal rate, currently 47% for resident taxpayers, which is a significant amount. We suggest making TFN collection part of your onboarding process from day one.
If your employees are paid in a foreign currency, the amounts need to be converted to Australian dollars for payroll tax and reporting purposes. The ATO accepts the use of average exchange rates for certain purposes, but it is recommended that you get specific guidance for your situation.
PAYG withholding and your compliance obligations
Pay As You Go (PAYG) withholding is the mechanism by which you deduct income tax from employee wages and remit it to the ATO on their behalf. It's similar to payroll tax withholding in other countries, but the rates, thresholds, and reporting cadence are specific to Australia.
The amount you withhold from each employee depends on their earnings and their tax circumstances, including whether they've claimed the tax-free threshold on their Tax File Number declaration. Australian payroll software calculates this automatically based on ATO tax tables, provided employee details are entered correctly.
PAYG withholding amounts are reported and paid to the ATO either monthly or quarterly, depending on the size of your payroll. You may want to confirm your reporting frequency with your accountant, as it's determined by your withholding amount and can change as your workforce grows.
At the end of each financial year (30 June in Australia), employees access their Income Statement through their myGov account, which is populated automatically under STP. You'll also need to finalise your STP data with the ATO by the required date. Missing end-of-year finalisation is a typical compliance gap for international businesses who aren't aware this is a separate step from their regular pay run reporting.
If you employ contractors rather than employees, different rules apply. Contractors manage their own tax obligations, but there are circumstances where you may still have withholding obligations, particularly if a contractor hasn't provided an ABN. The employee-versus-contractor distinction is carefully scrutinised by the ATO, so if your working arrangements sit in a grey area, seek advice from an accountant.
Know the risk of getting Super wrong
Employees can report non-payment of super directly to the ATO, and the regulator has the power to audit, investigate, and issue penalties without much notice. The penalties for payroll and superannuation non-compliance are deliberately punitive and include additional interest and administration fees that are not deductible against your taxable income. Payment of the SCG itself is now tax deductible.
The reputational cost is also worth considering. Australian employees understand their superannuation entitlements, and a business that doesn't pay correctly and on time reflects how it operates, leading to poor retention and the inability to attract strong talent.
