How a payroll tax accountant engagement works
A good process starts with a short discovery: business structure, entities in your group, where people work, how wages are processed, contractor arrangements and your current monthly wage totals. From there the work typically moves through three stages.
1) Liability and registration — Assess thresholds across states and territories, apply grouping rules, determine jurisdiction via nexus rules, then register with the relevant state revenue offices.
2) Workflow and categorisation — Configure your payroll or accounting software for accurate categorisation (wages, super, FBT, allowances, bonuses, leave, ETPs and contractors), document contractor exemption positions and map reporting to SRO portals.
3) Lodgement and review — Prepare monthly lodgements, manage payments, and complete the annual reconciliation to true-up and document positions. Where required, respond to SRO reviews or audits with supporting evidence.
Key Australian payroll tax rules to know
- Payroll tax is state and territory based. Thresholds and rates differ by jurisdiction and can change—check the current guidance for each SRO.
- Grouping rules can aggregate wages across related entities, which can trigger liability sooner and make members jointly and severally liable.
- Nexus rules determine which state gets the wages, based on where the employee works or is based—important for interstate teams and remote staff.
- Taxable wages commonly include salaries, superannuation, allowances, bonuses, directors’ fees, ETPs and grossed-up taxable fringe benefits.
- Contractor payments can be taxable unless a specific exemption applies; each arrangement must be assessed on facts and frequency.
- Most employers lodge monthly and then complete an annual reconciliation after year end to reconcile against the annual threshold.
- STP to the ATO is separate. You still need state payroll tax lodgements even if you meet all ATO payroll reporting obligations.
If you are unsure whether you are over a threshold, ask a payroll tax accountant to model your expected wages and grouping position.
What to compare before you commit
Scope
Confirm the engagement covers liability assessment, registrations, monthly lodgements, the annual reconciliation and contractor exemption review—not just “advice”.
Software fit
Check experience with your payroll stack (Xero Payroll, MYOB, KeyPay/Award interpretation, Employment Hero and similar) and how categories map to SRO reporting.
Turnaround and communication
Ask about month-end cut-offs, who reviews lodgements, how issues are escalated and how audit correspondence is handled.
When payroll tax becomes urgent
- Rapid headcount growth or wage increases push you over a state threshold mid-year.
- Multiple entities, related parties or a labour-hire model create a grouping exposure.
- You start paying people in another state or hire remote staff across Australia.
- Significant bonuses, super contributions or fringe benefits change your position.
- Heavy contractor use requires exemption analysis and documentation.
- You receive a review or audit letter from a State Revenue Office.
If any of these apply, act quickly—late registration and lodgement can attract interest and penalties. A payroll tax accountant can triage and stabilise the position.
What your payroll tax accountant actually does
- Models thresholds and grouping, then registers you with the correct SROs.
- Sets up categorisation rules for taxable wages, super, FBT, ETPs and allowances.
- Documents contractor exemption positions and maintains evidence files.
- Prepares and lodges monthly returns, manages due dates and payments.
- Completes the annual reconciliation and manages any true-up amounts.
- Responds to SRO queries or audits with schedules and supporting documentation.
Pricing and typical timelines
One-off review and registration: Scope and register in 1–2 weeks once information is provided. Faster options are often available if a deadline is near.
Ongoing lodgement: Fixed monthly fees based on headcount, states covered and complexity (contractor volume, FBT/ETP frequency, grouping).
Catch-up and audit support: Quoted per period or project, including data cleansing, contractor analysis and SRO correspondence.
Frequently asked questions
What is payroll tax and who pays it in Australia?
Payroll tax is a state and territory tax on wages paid or payable once your taxable wages exceed the local threshold. Employers are responsible for registration, lodgement and payment.
When do I need to register for payroll tax?
Register when your current or projected wages indicate you will exceed a threshold in a state or territory. Many jurisdictions require registration soon after liability arises and wages across grouped entities are aggregated.
What counts as taxable wages?
Typically salaries, bonuses, allowances, superannuation contributions, directors’ fees, certain termination payments and grossed-up taxable fringe benefits. Contractor payments may also be taxable unless an exemption applies.
How are contractors treated?
Some contractor payments are deemed wages. Exemptions can apply depending on the nature, frequency and duration of the services. Each arrangement should be assessed and documented.
What are grouping rules?
Common control or related business activities can group entities. Grouping aggregates wages for threshold calculations and can create joint and several liability across the group.
How often do I lodge and reconcile?
Most employers lodge monthly returns and complete an annual reconciliation after year end to reconcile against the annual threshold and confirm exemptions.
Does STP cover payroll tax?
No. Single Touch Payroll reports to the ATO and is separate from state payroll tax. You must still lodge and pay payroll tax with state revenue offices.
Can a payroll tax accountant help with audits?
Yes. They prepare schedules, evidence for contractor exemptions, respond to SRO questions and help resolve assessments or penalty remissions.
