Payroll tax in Australia: a state-by-state guide for employers

Payroll tax in Australia is administered separately by each state and territory, with different tax-free thresholds, rates and compliance requirements applying depending on where your employees work and the relevant state and territory rules. For employers operating across multiple jurisdictions, understanding these differences is essential to managing payroll obligations accurately and reducing compliance risk.

This guide explains how payroll tax works, how liabilities are calculated, which wages may be taxable and how requirements vary across Australia. It also covers multi-state wage allocation, grouping provisions, registration, recordkeeping and the role payroll technology can play in supporting compliance.

Payroll tax can become increasingly complex as businesses expand, hire remotely or operate across multiple states and territories. Clear processes, reliable location data and regular reviews can help employers manage their obligations more consistently.

Key insights

• Payroll tax is not one unified system. Employers work with eight state and territory frameworks, each with its own thresholds, rates and compliance requirements.
• Payroll tax generally becomes payable once taxable wages exceed the relevant state and territory thresholds. Taxable wages may include salaries, allowances, superannuation contributions and certain contractor payments.
• Multi-state employers face additional complexity because the applicable rules depend on where work is performed and the relevant nexus provisions, rather than simply where the business is headquartered or where a cost centre is recorded.
• Accurate wage allocation depends on reliable information about employees’ primary work locations, hybrid work patterns, interstate travel and relocations.
• Thresholds and rates may change. Employers should check the latest guidance from each revenue authority before lodging a return.
• Grouping rules may place related businesses under a shared threshold, changing registration and calculation requirements across the group.
• Clear records of wage totals, allocation methodologies, contractor assessments and grouping decisions can help support a defensible compliance position.
• Modern payroll systems can reduce manual administration by supporting wage allocation, calculations, reporting and audit-ready records across jurisdictions.
• Regular checks throughout the year can help identify reporting issues before annual reconciliation and reduce the risk of backpayments, interest or penalties.

Payroll tax in Australia: what it is and how it works

Payroll tax in Australia is a state and territory tax paid by employers when their taxable wages exceed the relevant threshold in a jurisdiction.

Because payroll tax is tied to wages rather than business revenue or profitability, it can represent a significant employment-related cost. The requirements become more complex when employees work across state or territory borders, as each jurisdiction has its own revenue authority, registration process, lodgment cycle and compliance requirements.

Multi-state employers therefore need a clear and consistently applied method for allocating wages and tracking obligations across locations. The Official Australian Government business portal provides a useful overview of payroll tax and links to the relevant state and territory authorities:

How payroll tax works

Most employers follow a similar process in each state or territory:

• Identify taxable wages for the relevant period, often monthly.
• Allocate wages to the appropriate state or territory under the applicable nexus rules.
• Apply the threshold and rate that applies in that jurisdiction.
• Lodge and pay by the due date, then complete any required annual reconciliation.

For multi-state employers, the main complexity is often wage allocation and the application of jurisdiction-specific thresholds and rates. Even when wage types are consistent, the treatment may differ depending on where wages are taxable.

Which wages are subject to payroll tax?

Payroll tax in Australia covers a broad range of wage types. Depending on the jurisdiction and circumstances, taxable wages may include:

• Salaries and wages
• Bonuses and commissions
• Allowances
• Employer superannuation contributions
• The taxable value of fringe benefits
• Certain contractor payments
• Some termination payments

Accurate recordkeeping is essential. For more detail, see ADP’s guide to payroll records:

If there is uncertainty about whether a payment is taxable, employers should document the treatment applied and check the guidance issued by the relevant revenue authority. This can help reduce the risk of later adjustments, interest or penalties.

Payroll tax rates and thresholds by state

Payroll tax rates and thresholds may change over time, and some jurisdictions apply different rates or rules depending on employer type, location or other circumstances.

The table below summarises the figures included in this article. Employers should verify all figures against the relevant revenue authority before relying on them.

*Rates and thresholds apply to the 2026–27 financial year and are current as at September 2026. Payroll tax liability may vary depending on total Australian taxable wages, payroll tax grouping, interstate wages, the period of employment, applicable deductions and exemptions, and eligibility for regional rates. Additional levies or surcharges may apply in some jurisdictions. Employers should consult the relevant revenue authority for guidance based on their circumstances.

Managing payroll tax across multiple states

When employees work across multiple states or territories, employers generally need to determine where wages should be reported for payroll tax purposes. While the specific rules vary between jurisdictions, employee location, principal place of employment and work patterns are often important factors in determining liability.

Get work location data right and keep it updated

Employers should maintain reliable records showing where employees perform their work. Relevant information may include the primary work location, hybrid work patterns, interstate travel and relocations, together with effective dates. Maintaining accurate information supports consistent wage allocation and reduces reporting risk.

Document how wages are allocated

An employee may be based in one state while regularly performing duties in another. In these situations, employers should establish a documented and defensible wage-allocation methodology that reflects the applicable jurisdictional rules and apply it consistently. Depending on the circumstances, supporting evidence may include timesheets, rosters, employment agreements and work-location records.

Review allocations regularly

Employers should reconcile payroll totals, taxable wage adjustments and wage allocations by jurisdiction against lodged returns throughout the year, rather than waiting until annual reconciliation. For example, if a remote employee relocates interstate but payroll retains an outdated location or cost centre, wages may be reported in the wrong jurisdiction.

Maintaining accurate employee work-location records and reviewing payroll tax treatment regularly can help reduce compliance risk, particularly for businesses with hybrid, remote or mobile workforces.

Understanding payroll tax grouping provisions

Grouping provisions may combine related businesses so that they share one payroll tax threshold. These provisions are intended to prevent businesses from dividing activities across entities to reduce or avoid payroll tax.

Entities may be grouped where factors such as the following apply:

• Common ownership
• Common control
• Shared employees
• Related business activities

Where entities form a payroll tax group, registration, return and threshold-entitlement requirements may apply across the group. Employers should check the rules of each relevant jurisdiction and seek professional advice where necessary.

Payroll tax registration requirements

As an organisation grows, it should monitor whether its taxable Australian wages are approaching or are likely to exceed the threshold in any state or territory. Where registration is required, the organisation must register with the relevant revenue authority and meet the applicable ongoing obligations.

Depending on the jurisdiction and circumstances, these may include:

• Lodging periodic payroll tax returns
• Completing an annual reconciliation
• Registering relevant entities within a payroll tax group
• Maintaining detailed wage and location records
• Notifying the revenue authority about relevant changes to the business structure

Monitoring thresholds and registration deadlines can reduce the risk of late registration, interest and penalties.

Employer recordkeeping and compliance obligations

Accurate records are essential to payroll tax compliance. Employers should keep documentation that supports:

• Wage totals and the treatment of taxable wages
• The wage-allocation methodology and supporting evidence, such as timesheets, rosters and work agreements
• Contractor assessments where relevant
• The organisation’s grouping position and supporting documentation

• Incorrect wage apportionment
• Omitting taxable contractor payments
• Assuming thresholds are the same in every jurisdiction
• Registering too late
• Misunderstanding grouping rules
• Using outdated rates or thresholds
• Maintaining incomplete records
