Why Payroll Gets Small Business Owners Into Trouble
Paying your employees seems straightforward — but Australian payroll compliance is one of the most layered obligations a small business owner faces. Get it wrong, and you're dealing with ATO penalties, Fair Work investigations, and back-pay liabilities that can run into the tens of thousands.
The moment you take on your first employee, you're immediately responsible for:
- Withholding the correct amount of PAYG tax from every pay run
- Making superannuation contributions to the right fund on time
- Reporting each pay cycle to the ATO via Single Touch Payroll (STP)
- Issuing compliant payslips within one business day of each pay run
- Applying the correct award rates, penalty rates, and allowances for your industry
And from 1 July 2026, there's a significant new obligation that every employer in Australia needs to be ready for: Payday Super.
PAYG Withholding: The Basics
PAYG withholding is the system by which you collect income tax from your employees' wages on behalf of the ATO — and remit it when you lodge your BAS.
Here's how it works in practice:
- Each pay run, you calculate the gross wages owed to each employee
- Using the ATO's tax withholding tables (which factor in the employee's Tax File Number declaration, tax offsets claimed, and residency status), you determine how much tax to withhold
- You pay the employee their net wages (gross minus withholding)
- You report the withholding to the ATO via STP and remit the amounts with your BAS
The amount you withhold depends on the employee's income level, whether they've claimed the tax-free threshold, and any HELP/HECS debt obligations. Xero and other payroll software calculate this automatically using the ATO's current tax tables — but it's your responsibility as the employer to make sure the inputs are correct.
Common PAYG mistakes:
- Using the wrong tax table (e.g., treating a resident employee as a non-resident)
- Not updating withholding when an employee's circumstances change (e.g., they stop claiming the tax-free threshold)
- Withholding the right amount but failing to remit it to the ATO on time
Unremitted PAYG withholding is treated seriously by the ATO and can result in both penalties and director liability in the case of companies.
Superannuation: What You're Required to Pay
From 1 July 2025, the Superannuation Guarantee (SG) rate is 12% of Ordinary Time Earnings (OTE) — this is the legislated rate and is not expected to increase further for the foreseeable future.
Most employees are entitled to super, including casual workers and some contractors. The definition of "employee" for super purposes is broader than many employers realise — it extends to some independent contractors who are paid wholly or principally for their labour.
What counts as OTE? Ordinary Time Earnings includes wages, salaries, commissions, allowances, and shift loadings. It generally excludes overtime payments — though this is a common area of error.
Super must be paid on time. Under the current rules, the quarterly super due dates are:
QuarterPeriodDue DateQ1July – September28 OctoberQ2October – December28 JanuaryQ3January – March28 AprilQ4April – June28 July
If you miss these dates, the ATO imposes the Super Guarantee Charge (SGC) — which is more punishing than simply paying the SG on time. The SGC includes the unpaid super amount, an interest charge of 10% per annum, and an administration charge. It's also not tax-deductible, unlike regular super contributions. In other words, paying super late costs you significantly more than paying it on time.
The Biggest Change in a Generation: Payday Super (From 1 July 2026)
This is the change that every Australian employer needs to be preparing for right now.
From 1 July 2026, under the Treasury Laws Amendment (Payday Superannuation) Act 2025, employers will be required to pay superannuation at the same time as wages — not quarterly. Super contributions will also need to reach the employee's super fund within 7 business days of each payday.
In practical terms:
- If you pay weekly, super must be paid weekly
- If you pay fortnightly, super must be paid fortnightly
- If you pay monthly, super must be paid monthly
This is the most significant change to Australia's superannuation system in decades. It was introduced to close the estimated $5–6 billion annual gap in unpaid super, with the ATO receiving increased funding to monitor compliance through enhanced STP reporting.
What This Means for Your Cash Flow
Under the current quarterly system, many businesses hold their employees' super contributions in their bank account for up to three months before paying them out. Payday Super eliminates that buffer. Super will leave your account every pay cycle in smaller, more frequent amounts — though the total annual cost doesn't change.
The practical impact: you need to plan your cash flow so that super is available every payday, not just quarterly. A good strategy is to set aside the super portion (12% of gross wages) into a separate account each pay run, just as many businesses already do for GST and PAYG. This makes the obligation predictable and prevents accidentally spending it.
The SBSCH Is Closing
If you currently use the ATO's Small Business Superannuation Clearing House (SBSCH) to pay super — be aware it is closing to all users from 1 July 2026. It stopped accepting new registrations from 1 October 2025.
You need to transition to an alternative SuperStream-compliant solution before 30 June 2026. Your existing payroll software (Xero, MYOB, etc.) will likely have a built-in clearing house option — contact your provider now to confirm their Payday Super readiness and make the switch well before the deadline.
Getting Ready for Payday Super: Your Checklist
- Review your payroll software — confirm it supports Payday Super and more frequent super payments
- Update employee super fund details — rejected contributions from outdated fund information are a common issue
- Understand the new Qualifying Earnings (QE) definition — it's slightly broader than the current OTE concept and includes salary sacrifice amounts
- Transition away from the SBSCH before 30 June 2026
- Model the cash flow impact of weekly or fortnightly super payments and adjust your working capital planning accordingly
Single Touch Payroll (STP): Real-Time ATO Reporting
Single Touch Payroll is the system that connects your payroll software directly to the ATO, reporting gross wages, PAYG withholding, and super information after each pay run. STP has been mandatory for all Australian employers since 2019.
Under STP Phase 2 (now fully rolled out), reporting is more granular — you're no longer just reporting a gross total. You're reporting each payment type separately: salary and wages, allowances, overtime, leave, and termination payments all need to be correctly categorised.
EOFY obligation: You must submit your STP finalisation declaration by 14 July each year. This finalises your employees' income statements in their myGov accounts, allowing them to lodge their tax returns. Missing this deadline can prevent your employees from accessing pre-filled tax data and may attract ATO attention.
Modern Awards: The Hidden Payroll Trap
The Fair Work Act requires most Australian employees to be paid at least the minimum rates set out in the applicable Modern Award for their industry or occupation. There are over 120 Modern Awards, each with its own pay rates, penalty rates, overtime rules, and allowance structures.
Getting award interpretation wrong is the number one cause of wage underpayment in Australia — and the Fair Work Ombudsman takes it seriously. The FWO secured $23.7 million in court-ordered penalties in recent years, and underpayment is increasingly treated as wage theft in states like Victoria and Queensland.
From 1 July 2025, the national minimum wage increased to $24.95 per hour (a 3.5% increase), and all Modern Award rates increased by the same percentage. If you haven't verified your pay rates since then, do so now.
Do You Need to Register for Payroll Tax?
Payroll tax is a state-level tax on wages paid by employers — and the thresholds vary by state. In Victoria, for example, the threshold is around $900,000 in annual wages. In some other states it's lower.
If your total Australia-wide payroll (wages, super, allowances, fringe benefits) approaches or exceeds the threshold in your state, you need to register and lodge returns with the relevant State Revenue Office. This obligation exists independently of your ATO obligations.
Many small businesses don't think about payroll tax until they've already tripped over the threshold — at which point penalties and back-assessments apply.
Why Outsourcing Payroll Makes Sense for Small Business
Payroll is one of the most time-sensitive, error-prone parts of running a business. Your employees need to be paid correctly and on time, every pay cycle — there's no tolerance for delays or mistakes.
For most small businesses with 1–15 employees, managing payroll in-house means:
- Keeping up with changing award rates, tax tables, and legislative obligations
- Ensuring STP is lodged correctly after every pay run
- Managing leave accruals, termination calculations, and fringe benefit reporting
- Getting ready for Payday Super by 1 July 2026
Outsourcing payroll to a bookkeeper like Girl Friday Australia means all of this is handled by a professional who stays current with ATO and Fair Work requirements — while you focus on the work that actually generates revenue.
Frequently Asked Questions
Do I need to pay super for casual staff? Yes — if a casual employee earns $450 or more in a calendar month (the monthly threshold was removed in 2022, so super is now payable from the first dollar earned for most employees), they're entitled to super. Check current ATO guidance for your specific situation.
What happens if I pay super late under the new Payday Super rules? Late payments trigger the Super Guarantee Charge, which includes the unpaid amount, 10% annual interest, and an administration fee. The SGC is also not tax-deductible. The ATO will have enhanced visibility through STP reporting to identify late payments quickly.
Can I use Xero for payroll? Yes — Xero's payroll module is STP Phase 2 compliant and supports Payday Super integration. Girl Friday Australia manages payroll for clients through Xero, handling everything from pay run processing to STP lodgement and super payments.
What if I've been underpaying staff and didn't realise? The Fair Work Ombudsman has a voluntary self-disclosure process. Identifying and rectifying underpayments proactively is treated far more favourably than underpayments discovered through a complaint or audit. If you're unsure whether your rates are correct, that's worth checking urgently.
