Payroll Tax in Australia: How Much Do You Need to Pay? (2026–27)

You hire another staff member, wages are up, sales are healthy, and then payroll tax lands on your desk like a punishment for doing well. That reaction is common. It’s also the wrong way to look at it.

Working out how much payroll tax you need to pay starts with a simple reality. This is not an employee tax. It’s a state and territory tax imposed on employers once taxable wages cross the relevant threshold, and the rules get messy fast if you operate in more than one state or use more than one entity. The businesses that get hurt aren’t always careless. Often, they’ve just grown faster than their systems.

If you’re close to a threshold, already over it, or running multiple related entities, the practical question isn’t “what is payroll tax?” It’s “what do I need to check right now so I don’t get blindsided?”

The Unexpected Tax Bill That Comes With Success

A small business owner hires their tenth employee, runs payroll, and thinks the hard part is covering wages and super. Then a letter arrives from the state revenue office asking about payroll tax registration. That’s usually the moment the issue stops being theoretical.

We see this with growing businesses that are organised enough to pay staff on time, lodge BAS, and keep the books clean, but haven’t built payroll tax forecasting into their routine. The shock usually comes from timing. They crossed a threshold months ago, nobody noticed, and now they’re dealing with registration, back-calculations, and a nervous review of every pay item.

Why owners get caught off guard

Payroll tax doesn’t announce itself clearly during the growth phase. It sits in the background while you’re focused on hiring, rostering, cash flow, and sales. If your payroll software isn’t being reviewed with state rules in mind, the first warning sign may come from outside the business.

A lot of owners also assume payroll tax is tied to business size in a broad sense. It isn’t. Liability turns on taxable wages, where workers are located, whether related entities must be grouped, and whether the threshold in that jurisdiction has been crossed.

Payroll tax is not a fine for success. It’s a compliance threshold that demands better systems the moment your business scales.

The smarter way to respond

The best response is not panic and not avoidance. It’s to treat the issue the same way you’d treat GST, PAYG withholding, or super guarantee. You check the facts, review the wage base, identify related entities, and fix the reporting cycle before the problem grows.

For many businesses, this is also the right time for a broader review. A payroll tax issue often exposes weak processes in forecasting, entity structure, and payroll coding. A wider business health check up guide can help you catch those problems before they show up elsewhere.

Why this matters: When you understand payroll tax as a normal growth checkpoint, you make better decisions and avoid reactive, expensive clean-ups.

What Actually Triggers a Payroll Tax Bill

A payroll tax bill starts when your taxable wages cross a state or territory threshold, not when your team reaches a certain headcount. That distinction matters because many businesses hit the threshold earlier than expected, especially after adding senior staff, paying bonuses, engaging labour-heavy contractors, or hiring across more than one state.

The main problem we see is owners tracking gross wages in the P&L and assuming that figure tells the whole story. It does not. Payroll tax uses a wider wage base, and if your business has more than one entity or staff working in different jurisdictions, the review gets more technical fast.

Taxable wages are broader than many businesses expect

Payroll tax usually covers more than salary and hourly pay. Depending on the jurisdiction and the worker arrangement, the wage base can include superannuation, paid leave, bonuses, commissions, some allowances, and contractor payments that are mainly for labour.

That is where first-time payroll tax exposure often starts. A business can stay under the threshold on base wages, then move over it once super, incentive payments, and contractor amounts are added back in.

Use this checklist when reviewing your wage base:

• Ordinary wages: Salary, hourly pay, paid leave, and similar earnings are usually included.
• Superannuation: Employers often miss this in early reviews. If you need to tighten up the wage concepts behind super, ordinary time earnings explained is a useful refresher.
• Bonuses and commissions: Variable pay can push you over the threshold sooner than expected.
• Contractor payments: If the arrangement is mainly labour, payroll tax may apply even when the worker is not treated as an employee for other purposes.
• Interstate wages: Staff working across jurisdictions can affect where you register and how liability is assessed.
• Related entities: Wages paid by connected businesses may need to be counted together under grouping rules.

Contractors and medical practices: Every state and territory has “relevant contract” rules that can treat payments to contractors as taxable wages, with exemptions such as services provided for 90 days or less in a financial year, or by a contractor who ordinarily provides those services to the public generally. Medical centres were caught out after the NSW Court of Appeal’s 2022 decision in Thomas and Naaz, which found payments to contracted GPs could be wages. Targeted relief now applies: NSW exempts unpaid tax on contractor GP payments made before 4 September 2024 and offers a rebate for practices that meet bulk-billing targets; Victoria exempts GP wages relating to fully funded (including bulk-billed) GP work from 1 July 2025; and Queensland exempts wages paid by medical practices to GPs from 1 December 2024. Other health businesses, such as dental and physiotherapy clinics, don’t get these concessions. If you’re unsure how a worker should be treated, start with employee or independent contractor.

The trigger is the wage base in the right jurisdiction

Payroll tax is applied at the state and territory level, but the analysis is rarely as simple as asking where the business is based. The location of the employee, where wages are paid, and whether wages must be grouped across entities all affect the result. That is why a business with one office can still end up registering in another state.

Multi-state operations create the most confusion. A Queensland business that hires a New South Wales manager, or a Victorian group that runs separate entities for operations and administration, can cross a threshold without any single payroll report making the issue obvious.

In practice, the trigger usually shows up through one of these events:

• hiring interstate staff
• moving contractors into labour-based engagements
• paying annual bonuses or commissions
• increasing super or salary packages
• expanding through related entities without reviewing grouping exposure

Review wages monthly once growth starts to accelerate. Do not leave this until year-end. By then, the registration date may already have passed, and the clean-up usually involves backdated returns, interest, and too much time spent reconstructing payroll data.

Why this matters: If you get the taxable wage base or the jurisdiction wrong, the tax calculation will be wrong from the start.

How Much Payroll Tax You Will Pay State by State

The first payroll tax problem for a growing business is usually a budgeting problem. You add interstate staff, wages push past the threshold, and the question changes from "do we need to register?" to "what will this cost us each month?"

The answer depends on more than the headline rate. Thresholds, deductions, phased reductions, and state-specific rules all change the result. For businesses operating in more than one state, the practical issue is cash flow. A rate that looks manageable on paper can still produce an unpleasant surprise if the threshold is reduced or the wage base is larger than expected.

The rates and thresholds for 2026–27

• New South Wales: 5.45% on wages above a $1.2 million annual threshold.
• Victoria: 4.85% on wages above a $1 million threshold (up from $900,000 on 1 July 2025). The threshold phases out for Australian wages between $3 million and $5 million, with no threshold above $5 million. Eligible regional employers pay 1.2125%, and surcharges apply to larger payrolls.
• Queensland: 4.75% where Australian wages are $6.5 million or less, and 4.95% above that, with a $1.3 million threshold. The deduction reduces by $1 for every $7 of wages above $1.3 million and cuts out at $10.4 million. Eligible regional employers get a 1% rate discount until 30 June 2030, and a mental health levy applies above $10 million.
• Western Australia: 5.5% with a $1 million threshold that diminishes as wages rise and cuts out at $7.5 million.
• South Australia: no tax on Australian wages up to $1.5 million; the rate rises on a sliding scale from 0% to 4.95% between $1.5 million and $1.7 million, and is 4.95% above $1.7 million.
• Tasmania: no tax on wages up to $1.25 million, 4% on wages from $1.25 million to $2 million, and 6.1% above $2 million.
• Australian Capital Territory: a $1.75 million threshold from 1 July 2026 (down from $2 million). The rate is 6.75% for employers with Australia-wide wages up to $20 million, 6.85% from $20 million to $50 million, and 7.35% to 8.75% for larger employers.
• Northern Territory: 5.5% with a $2.5 million threshold, which reduces by $1 for every $2 of Australian wages above $2.5 million and cuts out at $7.5 million. From 1 July 2026, employers or groups with Australia-wide wages of $100 million or more pay 6.5%.

In most states, the threshold is worked out on total Australian wages (across the whole group, if you’re grouped) and then apportioned to the share of wages paid in that state. Rates and thresholds also change regularly, as the ACT and NT changes from 1 July 2026 show. If you are close to the line, do not rely on a summary alone. Check the revenue office’s current figures before you register, budget, or lodge.

Where the calculation gets more technical

New South Wales applies payroll tax at 5.45% on wages above $1.2 million annually, as noted earlier.

Western Australia uses a diminishing threshold between $1 million and $7.5 million in annual taxable wages. In practice, that means the threshold benefit reduces as wages rise, rather than disappearing at a single point. For SMEs growing quickly, that can distort budgeting if the estimate assumes a full threshold all year.

Victoria needs close attention because the deduction and surcharge settings can change the effective cost. From 1 July 2025 the maximum annual deduction is $1 million ($83,333 a month), the general rate is 4.85%, and eligible regional employers pay 1.2125%. Employers and groups with annual taxable Australian wages between $3 million and $5 million get a reduced deduction, and above $5 million there is no deduction at all.

Victoria also applies two surcharges once Australian wages exceed $10 million: the mental health and wellbeing surcharge and the temporary COVID-19 debt surcharge. Combined, they add 1% on Victorian taxable wages above $10 million and 2% on Victorian taxable wages above $100 million. The COVID-19 debt surcharge is scheduled to apply until 30 June 2033.

Queensland has a similar mental health levy on top of payroll tax: 0.25% on Queensland taxable wages above $10 million, plus an additional 0.5% above $100 million.

South Australia uses a sliding scale: no tax up to $1.5 million, a rate that rises from 0% to 4.95% between $1.5 million and $1.7 million, and 4.95% above $1.7 million.

The ACT and the Northern Territory both changed their settings from 1 July 2026. The ACT cut its threshold to $1.75 million while lowering the rate to 6.75% for employers with Australia-wide wages up to $20 million. The NT kept its $2.5 million threshold and 5.5% rate, but introduced a 6.5% rate for employers or groups with Australia-wide wages of $100 million or more.

For first-time payroll tax clients, we focus on the effective liability, not just the published rate. A business with staff in Victoria and New South Wales may assume the tax cost is easy to estimate from two state rates. It rarely is. The actual calculation depends on where wages are taxable, whether any threshold is reduced, and whether related entities have already used part or all of the available deduction.

What this means for multi-state employers

If you employ across more than one state, do not budget payroll tax by multiplying gross wages by a single rate.

Start with three checks:

• which state has taxing rights over each employee's wages
• whether the threshold is fixed, reduced, or phased out in that state
• whether grouped entities or interstate wages affect the deduction available

That review usually tells you more than the rate table does. It also helps you avoid the common mistake of assuming each entity, or each state, gets a full standalone threshold.

Why this matters: Payroll tax is calculated under state rules, but the cost often turns on structure, location of wages, and whether concessions reduce as your wage bill grows.

The Grouping Rule A Common and Costly Payroll Tax Trap

The most expensive payroll tax mistakes usually don’t come from bad arithmetic. They come from bad assumptions about structure.

A common one is this. “They’re separate ABNs, so they’re separate for payroll tax.” Sometimes that’s wrong, and badly wrong.

Separate ABNs don’t guarantee separate thresholds

Grouping provisions can treat multiple entities as one employer for payroll tax purposes. If there is common control, shared ownership, family influence, or operational overlap, the state revenue office may aggregate wages across the group.

That’s why businesses with interstate employees or multiple entities get caught. Grouping is one of the most common payroll tax tripwires: once wages across commonly controlled entities are added together, the group can cross the threshold even though no single entity does. A group gets one threshold, claimed by a single designated group employer, rather than one threshold per entity.

A business owner might run:

• one company for consulting
• one trust with a corporate trustee for property operations
• another entity that employs admin staff shared across both

On paper, those businesses may look separate. In a payroll tax review, they may not stay separate for long.

What grouping usually looks like in practice

The practical warning signs are familiar:

• Common controllers: The same people own or control the entities.
• Shared staff: One employee works across businesses, or one entity pays wages on behalf of another.
• Integrated operations: The businesses use the same premises, management, or back-office systems.
• Family structures: A company, a trust, and another company may still be grouped if the control pattern points that way.

If that sounds close to your setup, structure matters. This isn’t just a bookkeeping issue. It’s part of the legal and tax architecture of the business, and that’s why understanding the legal structure of a business in Australia matters well before payroll tax becomes urgent.

One of the worst payroll tax files to inherit is the one where each entity looked harmless on its own, but the group had crossed the threshold years earlier.

Some groups may be able to seek exclusion where the businesses are independent in the way they operate. But that argument only works when the facts support it. Cosmetic separation won’t help.

Why this matters: Grouping can turn a manageable payroll issue into a retrospective tax problem across multiple years, with penalties and interest layered on top.

A Worked Example Calculating Your Payroll Tax Liability

A business usually discovers its payroll tax problem after a strong quarter, not during a quiet one. Revenue is up, headcount has grown, and then someone asks a simple question: have total wages across the group now crossed the threshold?

Use a worked example to answer that question properly.

A practical scenario

Take Coastal Cafes Pty Ltd, with employees in Sydney and Melbourne and a related entity that handles some head-office functions. This is the point where many owners make the wrong assumption. They look at each payroll in isolation, apply one threshold, and move on. That shortcut is where first-time payroll tax liabilities get missed.

The safer method is a file-based calculation that can survive review later.

1. Build the taxable wage base: Start with total Australian wages, then adjust the figure to reflect payroll tax treatment. That means checking more than salaries and wages. Superannuation, some contractor payments, bonuses, allowances, fringe benefit amounts in some cases, and termination-related payments may need review depending on the facts and the state rules.
2. Allocate wages to the correct state: Sort wages by jurisdiction before calculating any liability. For fixed-location staff, this is usually straightforward. For managers travelling between states, remote workers, or employees paid by one entity while working for another, record the basis for the allocation while the facts are still clear.
3. Check whether the business stands alone: If there is a related company, trust, or service entity anywhere in the structure, test grouping before you touch the threshold. Multi-entity businesses are frequently caught by these provisions, and the result can change materially once related wages are pulled into the same calculation.
4. Work out whether the threshold must be apportioned: A business operating in one state has a simpler calculation. A business with wages in more than one state usually does not. The threshold is generally shared in proportion to where the wages are paid, and the answer depends on whether the business is grouped.
5. Apply the state rate and any reduction rules: Once the taxable wages for each jurisdiction are settled, apply the correct rate and deduction treatment for that state. Do not assume the same method works across NSW and Victoria. It often does not.

Here’s how the numbers could look. Say Coastal Cafes and its related head-office entity are grouped, and the group’s total Australian taxable wages for 2026–27 (including super) are $2.4 million: $1.6 million paid in NSW and $800,000 in Victoria. The group claims one threshold in each state, apportioned by the share of Australian wages paid there.

• NSW: two-thirds of the wages are paid in NSW, so the group gets two-thirds of the $1.2 million threshold, or $800,000. Payroll tax is ($1,600,000 − $800,000) × 5.45% = $43,600.
• Victoria: group wages are under $3 million, so there’s no phase-out, and one-third of the $1 million threshold is $333,333. Payroll tax is ($800,000 − $333,333) × 4.85% = $22,633.
• Total: about $66,233 for the year, or roughly $5,500 a month of cash flow to plan for.

Here is the practical lesson. Payroll tax calculations rarely fail because the arithmetic is hard. They fail because the wage base was incomplete, the state allocation was weak, or the business applied a threshold before dealing with grouping.

One mistake shows up repeatedly in first-year reviews. Superannuation gets left out of the payroll tax wage base. The result is a business that appears to be under the threshold on an internal spreadsheet, but is over it once the taxable components are corrected.

Victoria also needs careful handling because the deduction position can change as wages increase. If your business has grown quickly or operates across states, do not rely on a rough estimate. We usually recommend checking the payroll system mapping at the same time, especially if the business has outgrown basic setup choices in its software. A review of the best payroll software for Australian businesses can help if your current system does not separate state wages cleanly or produce defensible reports.

A calculation file worth keeping should show:

• The payroll reports used to arrive at total wages
• The adjustments made for superannuation, contractors, and other taxable components
• The state allocation working papers for interstate or mobile employees
• The grouping conclusion and the facts supporting it
• The threshold and rate treatment applied in each relevant jurisdiction
• A clear reconciliation between payroll system totals and the lodged figures

That level of documentation saves time later. If a revenue office asks how the number was calculated, the business should be able to show the logic, not just the result.

Lodging and Reporting Your Payroll Tax Obligations

A common turning point looks like this. The business has crossed the threshold, the tax estimate has been done, and everyone assumes the hard part is over. Then the first problems show up. Registration is late, the wrong entity lodges, interstate wages are reported inconsistently, or the annual reconciliation does not match the payroll file.

Once payroll tax applies, accuracy alone is not enough. The process has to work every month, across the right states, under the right entity, with records that hold up if a revenue office reviews them.

What happens after you become liable

The first step is registration in each jurisdiction where the business has a payroll tax obligation. Timing matters. Waiting until year end usually creates avoidable interest, catch-up lodgements, and a rushed reconciliation exercise.

After registration, build the reporting cycle into your finance routine:

• Register with the relevant revenue office: Do it as soon as it is clear the threshold has been crossed or will be crossed.
• Confirm the lodgement frequency: Monthly is common, but smaller liabilities may be treated differently depending on the jurisdiction.
• Assign responsibility internally: One person should own the return process, and another should review it.
• Reconcile payroll to lodged returns regularly: Do not leave errors sitting in the file until the annual adjustment.
• Track state wages separately: Multi-state employers often encounter difficulties, especially if staff move, work remotely, or are paid through one central payroll.

For a business with more than one employing entity, add one more check. Confirm that the entity lodging the return matches the structure analysis and any grouping position already reached. We regularly see businesses calculate the right number, then report it under the wrong entity or wrong state split.

Software can help if it is configured properly. If your system struggles to separate wages by state, entity, or employee location, review whether your setup is still fit for purpose. Our guide to the best payroll software for Australian businesses is a useful starting point.

Records that matter

Keep records that support the treatment adopted in the return. A pay run summary on its own is not enough if the issue is grouping, contractor treatment, or interstate wage allocation.

A defensible file usually includes:

• Payroll reports: Gross wages, superannuation, allowances, bonuses, and taxable adjustments
• Entity support: Which entity employed each worker and how that was determined
• State allocation records: Timesheets, work location records, employment contracts, and payroll coding for interstate employees
• Contractor analysis: Agreements, invoices, and notes showing why payments were included or excluded
• Lodgement reconciliations: Clear tie-outs between payroll reports, monthly returns, payment records, and the annual reconciliation

Late lodgement and late payment get expensive quickly. The direct tax cost is only part of the problem. In practice, the bigger issue for many SMEs is the clean-up work that follows. Rebuilding missing reports, correcting prior periods, and answering revenue office queries often takes more time than the original lodgement would have.

Good payroll tax compliance is repetitive by design. If the process depends on memory, it will fail under pressure.

Why this matters: A correct calculation does not protect the business if registration is late, returns are inconsistent, or the file cannot support the position taken.

Final Verdict Your Payroll Tax Action Plan

If payroll tax has just entered the conversation in your business, don’t overcomplicate the first move. Start with a clean review and a written action list.

Your next steps

Use this checklist.

• Audit your wage base: Review salaries, super, bonuses, allowances, and contractor arrangements that may be taxable for payroll tax.
• Check every entity: List all companies, trusts, and employing entities connected to the business. Grouping problems often start with incomplete structure maps.
• Map staff by location: If you employ across state lines, identify where each worker is employed and keep records that support that treatment.
• Forecast before year-end: Don’t wait until the annual accounts are done. Track wages through the year so threshold issues show up early.
• Review your reporting cycle: Once liable, make registration, return preparation, payment, and annual reconciliation part of the accounting calendar.
• Keep working papers: Save the calculations and reasoning. If the revenue office asks questions later, you need a file, not a memory.
• Escalate structure issues early: If you have more than one entity, family ownership overlap, or shared employees, get the grouping position reviewed before lodging assumptions as fact.

A lot of owners look for a shortcut here. There usually isn’t one. The businesses that stay out of trouble are the ones that accept payroll tax as an ongoing management task, not a once-a-year form.

Set a quarterly payroll tax review in the same rhythm as your BAS and management accounts. That’s the easiest way to spot threshold pressure before it becomes a lodgement problem.

So how much payroll tax do you need to pay? The honest answer is that the amount depends on your state, your wage base, your structure, and whether grouping or apportionment changes the result. The practical answer is simpler. You need a system that picks up the issue early and a review process that doesn’t ignore the awkward details.

Why this matters: A written action plan turns payroll tax from an unpleasant surprise into a controlled compliance task.

Payroll tax FAQs

Is payroll tax the same as PAYG withholding?

No. PAYG withholding is a federal amount you deduct from employees’ pay and send to the ATO, and it counts toward each employee’s own income tax. Payroll tax is a state and territory tax the employer pays from its own funds, on top of wages, and only once wages pass the threshold in that jurisdiction.

Does superannuation count as wages for payroll tax?

Yes. Employer super contributions, including super guarantee and salary sacrificed amounts, are generally taxable wages for payroll tax in every state and territory, so they count toward the threshold. Leaving super out is one of the most common reasons a business thinks it’s under the threshold when it isn’t.

When do I need to register for payroll tax?

Generally once your Australian wages, or your group’s, exceed the monthly threshold in a state or territory where you pay wages. Each revenue office sets its own registration deadline, usually shortly after the end of the month, so register as soon as you cross the line rather than waiting for year-end.

Is payroll tax tax-deductible?

Payroll tax is generally deductible to the business as an ordinary business expense in the income year it’s incurred. That reduces the after-tax cost, but it doesn’t change how much you owe the state revenue office.
