Payroll tax is a state and territory-based tax that businesses must pay on the total wages paid to their employees once they exceed a certain threshold. In FY2026, New South Wales applies 5.45% above $1,200,000, Victoria applies 4.85% above $900,000 with additional surcharges for some larger employers, Queensland applies 4.75% up to $6.5 million and 4.95% beyond that above a $1.3 million threshold, and the Australian Capital Territory applies 6.85% above $2 million.

You usually realise payroll tax matters when the business has grown faster than the systems around it. A practice adds contractors, a family group splits operations across entities, or a new migrant business owner assumes each company stands alone, then discovers state revenue rules look at the wider picture.

Defining Payroll Tax and Its Purpose in Australia

Payroll tax is a self-assessed state tax on employer wage bills, not an income tax on employees. Employers calculate and report their own liability to the relevant state or territory revenue office once their taxable wages exceed the applicable threshold. The wage base is broader than many owners first expect, because it can include wages paid before tax and deductions, fringe benefits, and certain contractor payments, as noted in the Australian payroll tax by state guide.

Payroll tax has been with us a long time. It was first introduced in 1927 as a temporary wartime measure to fund the Family Endowment Fund, and it has since become a permanent state revenue source according to Business NSW on why payroll tax still exists.

Here's the core wage concept most businesses need to understand:

• Employee wages: ordinary salary and wages paid to staff form part of the payroll tax base.
• Additional remuneration: bonuses, commissions, and allowances can also fall into taxable wages depending on the applicable state rules.
• Superannuation and benefits: employer-paid superannuation contributions and fringe benefits may be included in the taxable wage calculation.
• Contractor arrangements: some contractor payments are treated like wages for payroll tax purposes, which is why contractor drafting matters.
• Gross basis: the tax looks at remuneration before employee tax withholding and other deductions.

A practical mistake is treating payroll tax as a payroll software issue rather than a structure and contract issue. It often starts with payroll data, but the answer may sit in service agreements, director overlap, and worker classification. That's why businesses reviewing payroll tax should usually also review employment law compliance and their entity setup.

Practical rule: If money is being paid for labour, don't assume it sits outside payroll tax until the legal basis for exclusion has been checked.

For readers comparing Australian employer obligations with overseas withholding systems, DynamicsHub's PAYE insights can be useful background. It's still important to remember that Australian payroll tax is a separate state-based obligation with its own logic, and it sits beside other business decisions such as Australian business structures.

The key takeaway is that payroll tax isn't just “tax on wages”. It's a state-based compliance system built around a broad wage concept, self-assessment, and legal interpretation.

Who Pays Payroll Tax? State Thresholds and Rates for 2026

A common first trigger is growth that looks harmless on paper. A business opens in a second state, shifts a few employees between entities, or hires under a service company arrangement. The owner still sees a modest operation. The revenue office looks at taxable wages, nexus rules, and sometimes the wider group.

You may need to register when your total Australian taxable wages exceed a state's threshold, even if the wages attributable to that state are relatively low. That catches small to medium businesses more often than expected, especially new market entrants who assume payroll tax is tested office by office.

The table below sets out the headline thresholds and rates business owners usually ask for first, current as at 07/2026.

These are headline figures only. They help with initial screening, but they do not answer the full liability question. State rules differ on threshold access, wage attribution, rebates, surcharges, and special concessions. Medical practices should be especially careful here, because relief measures and amnesties in one state do not create a safe position in another.

What the thresholds actually tell you

Thresholds are not a switch that turns tax on in one state once local wages pass a number. Registration and liability often depend on total Australian taxable wages, while the taxing right for particular wages depends on where the employee is based and how the state nexus rules apply. That is why interstate growth can create payroll tax work before a business feels large.

Victoria is a good example of why the headline threshold is only the starting point. For larger employers, threshold benefits can reduce or disappear as wages increase, and surcharge settings may apply at higher national wage levels. A business that budgets using only the standard rate can understate its exposure.

Why this catches smaller operators

Many owners judge size by turnover, headcount, or whether they still fit the small business definition in Australia. Payroll tax does not use that commercial shorthand. It looks at taxable wages, related entities, and state-specific rules.

That creates hidden risk in three common situations:

• Interstate expansion: one payroll grows into two states, but registration is still assessed by reference to total Australian wages.
• Related entities: wages may look modest in each entity, yet the threshold position changes once grouping is considered.
• Industry-specific arrangements: contractor, practitioner, and service-fee models can produce payroll tax issues even where the business believed it had kept employment costs outside the payroll.

A practical review should ask three questions early:

• What are total Australian taxable wages?
• Which state has taxing rights over each wage payment?
• Could another entity, trust, or service company affect the threshold position?

Payroll tax problems often start as a threshold question and end as a structural review.

Who pays payroll tax is determined by more than a single wage figure. The answer depends on state thresholds, where wages are taxable, and whether the business stands alone or forms part of a wider group.

The Hidden Risk of Grouping Provisions

Many business owners assume payroll tax applies entity by entity. That assumption is where some of the biggest mistakes begin. Legislation in each state can group entities where there is common control or shared employee usage, and liability can arise when total group wages exceed the threshold, not just one entity's wages, as outlined in this grouping discussion for payroll tax.

For medical practices, family groups, and new entrants to Australia, grouping is often the overlooked issue that turns a manageable compliance task into a retrospective problem.

Castle Medical GP partnership example

Take Castle Medical GP partnership. The doctors operate through one entity, reception staff are paid from another, and a related service company handles some administration. On paper, each entity's wages may look modest. In practice, if employees work across the entities or control is sufficiently connected, the state revenue office may treat them as a group.

That changes the question from “Did this company cross the threshold?” to “Did the group cross the threshold?” For a medical centre, that distinction matters because contractor arrangements, service entity structures, and billing models often already sit in a grey zone.

A useful review usually looks for these signs:

• Shared employees: the same receptionist, nurse, manager, or administrator works across more than one entity.
• Common decision-makers: directors, shareholders, trustees, or partners effectively control multiple entities.
• Operational integration: related entities share premises, systems, funding, or labour in a way that makes separation more formal than real.

Why grouping catches new market entrants

Wei, a new Sydney migrant professional, might establish separate Australian entities for risk management or commercial presentation. That approach can be sensible. But if the same people control them, and staff are shared or seconded informally, payroll tax may still look through the structure.

This is where related party transactions become more than an accounting disclosure issue. They can change the payroll tax position materially.

A clean corporate chart doesn't always produce a clean payroll tax result. State revenue offices look at how businesses actually operate, not only how documents are labelled.

The hidden trap for medical practices

Medical practices face an extra complication because grouping can interact badly with industry-specific exemptions or concessions. Some recent changes have created relief in some jurisdictions for certain medical arrangements, but relief doesn't automatically neutralise grouping. A practice may still need careful entity-by-entity and group-by-group analysis before concluding that no payroll tax is payable.

The takeaway is that grouping provisions can turn several sub-threshold businesses into one taxable employer group. If you ignore grouping, you may understate payroll tax exposure even when each entity looks small on its own.

How Do You Calculate and Report Payroll Tax?

A business can stay under the threshold on paper and still have a payroll tax problem once the full wage base is pulled together properly. Calculation is straightforward in principle. The risk sits in the inputs.

You calculate payroll tax by identifying taxable wages in the relevant state, applying any threshold entitlement that remains available, and self-assessing the liability through the state revenue office. That sounds simple until contractor payments, interstate wages, fringe benefits, superannuation, and grouped entities are involved.

Worked example for Tom in Brisbane

Tom runs a growing electrical business in Brisbane. His Queensland taxable wages for the year are $1.5 million, and assume for this example that he has no grouped entities, no interstate complications, and no exempt wage components.

Using the Queensland threshold and rate noted earlier in the article, Tom has $200,000 above the threshold. At a 4.75% rate, the payroll tax comes to $9,500.

That example is intentionally clean. Real calculations often change once an owner checks whether contractor payments are taxable, whether wages must be split across states, and whether another entity should be included because of grouping. For new market entrants and expanding businesses, that last issue is often the one that turns a modest payroll review into an actual liability.

A practical process usually looks like this:

1. Work out the wage base. Review salaries and wages, superannuation, fringe benefits, bonuses, allowances, termination payments where relevant, and contractor payments that may be caught under payroll tax rules.
2. Identify the correct state position. Payroll tax is state-based, so the wage allocation rules matter if employees work across jurisdictions.
3. Check whether grouping changes the threshold. If entities are grouped, the threshold may need to be shared or may already be used elsewhere in the group.
4. Apply the rate to the taxable amount. The rate depends on the state and, in some cases, the size or profile of the employer.
5. Register, lodge, and reconcile. Businesses generally lodge periodic returns and then complete an annual reconciliation to match what was reported during the year against the final legal wage base.

The grouping point deserves extra attention here because it changes the calculation itself, not just the background risk analysis. I regularly see owners calculate payroll tax entity by entity because that is how their bookkeeping file is set up. State revenue offices do not have to accept that approach if the entities form a group.

Reporting and correction

Payroll tax is reported to the relevant state revenue office, not the Australian Taxation Office. A business can be fully up to date with PAYG withholding, Single Touch Payroll, and superannuation and still have missed payroll tax registration altogether.

That happens often in medical and professional service structures. A practice may assume service trust payments, contractor doctor arrangements, or related entities sit outside payroll tax, then find that state-specific administrative changes or amnesty programs only provide limited relief and only on stated conditions. Queensland and South Australia have both shown how quickly the position can change for medical practices. Relief should be read carefully. It does not remove the need to calculate the liability correctly.

Good reporting depends on good coding. If payroll categories are already causing reconciliation issues, review them alongside your BAS coding and reporting processes, because the same classification errors often affect both areas.

Adviser's note: The safest routine is a periodic review of wages, contractor arrangements, and entity changes during the year. Year-end cleanup is usually too late, especially where grouping or state allocation has been missed.

Payroll tax is a self-assessment obligation. Calculate it from the legal character of the payments and the operating structure, not from labels in payroll software or assumptions borrowed from income tax.

Common Payroll Tax Exemptions

A payroll tax exemption only applies where the state law clearly allows it and the facts line up with that rule. In practice, the trap is rarely the headline exemption itself. It is the business structure around it, especially where grouped entities, related service companies, or mixed activities blur what is exempt and what is still taxable.

Charitable and not-for-profit employers are the clearest example. Some wages paid by eligible charities can be exempt, but eligibility turns on the entity's legal status, its actual activities, and the state rules being applied. A related entity in the same group does not become exempt by association. If a business is reviewing whether its structure supports charitable status, the guide to setting up a charity is a useful starting point.

Leave payments also need careful treatment. Some categories are excluded under payroll tax law, but the exclusion depends on the type of leave and how the payment is characterised. Payroll systems often bundle items together in ways that hide the legal distinction.

Industry-specific relief deserves extra caution. Medical practices have seen this first-hand. Concessions, amnesties, or administrative relief in one state may be temporary, conditional, or limited to a particular class of arrangement. They do not create a general exemption, and they do not necessarily carry across to another state.

A practical review usually starts with these questions:

• Which entity is paying the wages? Exempt status must sit with the right legal employer.
• Is the entity grouped with others? Grouping can affect threshold access and expose taxable wages in related entities, even where one entity has a concession or partial exemption.
• What exactly is the payment? Leave, allowances, fringe benefits, and contractor amounts should be tested by legal character, not payroll label.
• Which state law applies? Exemptions and concessions differ by jurisdiction and can change with little notice.
• Has the business changed during the year? New entities, acquisitions, practice restructures, and service company arrangements often alter the answer.

I often see two expensive mistakes. One is claiming an exemption too broadly because another adviser, payroll officer, or business owner mentioned a rule from a different state. The other is never claiming an available exemption because no one revisits the structure after the business grows or reorganises.

Exemption analysis works best when it is documented. Keep the legal basis, entity details, payment categories, and state-by-state reasoning on file. If the revenue office reviews the position later, that record matters as much as the calculation itself.

Frequently Asked Questions About Payroll Tax

Do contractor payments count as wages for payroll tax?

They may. Some contractor payments are included in taxable wages for payroll tax purposes, so a business shouldn't assume that calling someone a contractor keeps the payment outside the payroll tax net. The legal arrangement, the actual work pattern, and the state rules all matter. If the contract is central to the answer, get it reviewed.

If my employee works across states, which state gets counted?

Payroll tax is state-based, but the liability test can depend on total Australian taxable wages. Where employees work across states, apportionment and nexus issues may need review under the relevant state rules. The common mistake is treating each payroll location in isolation when the broader wage position is what triggers registration.

I'm a sole trader. Do I pay payroll tax?

A sole trader doesn't pay payroll tax just for drawing money personally from the business. But once the sole trader hires staff, payroll tax may arise if taxable wages exceed the relevant threshold. Dr Anya Sharma in Sydney, for example, may begin as a solo operator and later become exposed once employment arrangements expand.

Are fringe benefits part of payroll tax?

They may be. Payroll tax can apply to wages paid before tax and deductions, including fringe benefits. Businesses often miss this because fringe benefits are already being dealt with elsewhere for tax reporting, but payroll tax has its own wage-base rules and should be reviewed separately.

Can a small medical practice be liable even if each entity is under the threshold?

Yes. Grouping provisions can combine the wages of related entities where there is common control or shared employees. That is one reason small medical practices can face unexpected payroll tax exposure. If you need advice on a specific structure, contact Everglow for personalized guidance.

If I made a mistake in earlier years, should I wait for the revenue office to raise it?

Usually, waiting isn't the strongest position. Payroll tax is self-assessed, and some jurisdictions have offered amnesty or relief pathways in specific contexts, especially for medical practices. The sensible response depends on the state, the contracts, and the period involved. Early review often gives you more options than a defensive response after a formal query.

The core answer remains the same. Payroll tax is a state-based employer tax on taxable wages above a threshold, but compliance risk often sits in grouping, contractor treatment, and state-specific exceptions rather than the headline rate alone.
