Many Queensland businesses rely on subcontractors for specialised skills and flexible staffing. The catch is that money paid to those subcontractors can be treated as wages for payroll tax. When you add those payments to ordinary employee wages you can sail past the 1.3 million dollar annual threshold without realising it. The moment that combined figure is breached you must register and start remitting payroll tax, with penalties and interest looming if you do not. This guide explains in plain language when subcontractor payments count, how the exemptions work and the practical steps you can take to stay on the right side of the Queensland Revenue Office.
Why subcontractor payments matter for Queensland payroll tax
Payroll tax in Queensland is a state tax on taxable wages. Employee salaries, bonuses and allowances sit clearly in that bucket, but contractor payments occupy a grey space that often surprises business owners. The Payroll Tax Act contains a set of contractor provisions that deem many service contracts to be relevant contracts. Where a contract is relevant, every dollar paid to the contractor in connection with the work is treated as wages unless an exemption applies.
Because this deeming rule applies to the principal who receives the services, a plumbing company, an IT provider or a café group might find that payments to labour-only subcontractors inflate its wage bill well beyond expectations. That inflation can push a previously unaffected business over the 1.3 million dollar threshold and trigger both registration and monthly lodgement duties.
For grouped entities the risk is even larger. The threshold applies to the combined Australian taxable wages of every entity in the group, so subcontractor expenditure in one company may tip another company into liability.
What counts as taxable wages in Queensland
Queensland defines taxable wages broadly. The definition covers employee remuneration such as salaries, wages, commissions, superannuation contributions, fringe benefits, termination payments and shares or options. Added to that list are payments made under a relevant contract.
To calculate payroll tax you tally all taxable wages paid anywhere in Australia during the financial year. You then apportion the total that relates to Queensland employees or contractors if you operate across states. If the Queensland amount, when combined with any other Australian wages for threshold purposes, exceeds the 1.3 million dollar annual limit you pay payroll tax at 4.75 percent up to 6.5 million dollars and 4.95 percent on the excess. Larger employers also face the mental health levy once wages reach 10 million dollars. A one percent discount applies for regional employers until June 2030.
GST is excluded from contractor payments before including them as wages. If the contractor supplies both labour and materials you may be able to deduct an approved industry percentage for the materials component. The Queensland Revenue Office publishes deduction percentages for trades such as bricklaying, carpentry and electrical work.
Understanding a relevant contract
A relevant contract exists when a person supplies services to another person under a contract for the performance of work. The definition is intentionally wide and captures most arrangements where the substance of the deal is the provision of labour. It also covers situations where goods are resupplied after being worked on, but the most common trigger is a straightforward service contract.
Once a contract falls within this definition the principal is deemed to be the employer and the payments are deemed to be wages unless an exemption applies. The contractor does not have to be an individual. Companies, trusts and partnerships can all be contractors for payroll tax purposes. The deeming rule applies even if the contractor has an Australian Business Number, issues tax invoices and meets the tests for an independent contractor under common law.
Because the starting position is that every service contract is relevant, business owners need to work through the exemption list carefully to decide whether any of their subcontractors can be carved out.
First hurdle - is your contractor actually an employee
Before diving into the exemption rules you should confirm whether the worker is a genuine contractor or in fact an employee at law. If the person is an employee, the ordinary payroll tax provisions apply and there is no need to consider the contractor deeming rules. The Queensland Revenue Office looks at factors such as control, integration, ability to delegate, provision of tools, and risk of profit or loss. If the worker is integrated into your business, follows your directions, uses your equipment and has no real chance to make a profit beyond the agreed rate, the office is likely to treat the arrangement as employment.
If your analysis supports contractor status you then move to the relevant contract test outlined above. From that point, you assume the contract is relevant unless an exemption applies.
The nine contractor exemptions explained
To avoid payroll tax on contractor payments you only need one exemption to apply. Each exemption focuses on a different aspect of the commercial relationship.
The first exemption is the ninety-day rule. If an individual contractor or a contracting entity provides services to you on no more than ninety days in a financial year the payments are exempt. The days do not have to be consecutive. You must keep evidence of the days worked to rely on this rule.
The second exemption looks at whether the contractor uses at least two workers to perform the services. Workers can be employees, subcontractors or partners of the contractor. If the contractor engages help on at least eighty percent of the work, the principal is off the hook for payroll tax on those payments.
The third exemption applies when labour is ancillary to the supply of materials or equipment. For instance, a cabinet maker who installs custom joinery may supply both the cabinetry and installation labour. If the labour component is incidental to the goods supplied the payments can fall under this exemption.
The fourth exemption relates to services required for less than one hundred and eighty days in a financial year. This rule focuses on the needs of the principal rather than the contractor. If your business normally needs the service for fewer than one hundred and eighty days a year the payments can be exempt, even if the contractor personally works more than one hundred and eighty days.
The fifth exemption covers services not ordinarily required by the business. A marketing agency that only occasionally hires a painter to refresh its office walls can rely on this rule as painting services are outside the ordinary scope of the agency’s business.
The sixth exemption is available where the contractor provides the same type of services to the general public during the financial year. The contractor must operate an independent business of the same service and must not work predominantly for the one principal.
Two more exemptions apply to owner-drivers and door-to-door salespersons subject to specific conditions. The final exemption allows the Commissioner to grant relief in special circumstances.
Record keeping is essential for every exemption. You must keep documents such as invoices, timesheets, contracts and proof of other clients for at least five years to satisfy the Queensland Revenue Office if audited.
How subcontractor spending can push you over the 1.3 million dollar threshold
Consider a Queensland construction firm that employs carpenters and apprentices with an annual wage bill of 900 000 dollars. The firm also pays bricklaying subcontractors 550 000 dollars for the year to keep projects on schedule. Management believes subcontractors sit outside payroll tax and does not register. However, the payments to bricklayers are made under relevant contracts and no exemption applies because the contractors work most days and use only one worker.
The total taxable wages are therefore 1 450 000 dollars, exceeding the 1.3 million dollar threshold. The firm should have registered within seven days after the month in which its Australian taxable wages first exceeded the threshold. Instead, it now faces back tax of roughly 71 000 dollars at 4.75 percent, plus unpaid tax interest and potential penalty tax of up to twenty percent.
Grouping can create an even nastier surprise. Suppose the construction firm is part of a family group that also owns a separate property maintenance company with a wage bill of 500 000 dollars. The companies share common control so they form a payroll tax group. The combined Australian taxable wages across the group are now 1 950 000 dollars and payroll tax is payable on the full amount above the threshold, not just the excess attributable to subcontractors.
Common traps for tradies builders and service businesses
Trades and service industries rely heavily on flexible labour, so they are most exposed to payroll tax on subcontractor payments. Businesses often assume that because they issue tax invoices to each other and use ABN details the arrangement is safe from payroll tax. That is not the test used by the Queensland Revenue Office.
Another trap is confusing state payroll tax with the federal taxable payments annual report. A building business may dutifully lodge its TPAR but still fail to register for payroll tax on the same payments.
Group aggregation is also easy to overlook. Family trusts and operating companies might be set up for asset protection, yet for payroll tax, they can form one group. Proximity to the threshold can change overnight when a new entity joins the group.
Finally, many businesses do not keep records that support exemptions. Without evidence the Queensland Revenue Office will assume payments are taxable.
Practical review checklist
First, list every person or entity you pay for services. Separate this list from your employee payroll.
Second, consider whether any of those workers are employees in substance. If yes, include their payments as wages immediately.
Third, treat every remaining service contract as relevant by default. Work through each exemption and document the evidence supporting any exemption you believe applies.
Fourth, calculate your annual Australian taxable wages after adding all non-exempt contractor payments. If the total is close to or over 1.3 million dollars run a monthly test against the registration trigger set by the Queensland Revenue Office.
Fifth, confirm whether you are part of a payroll tax group. If other related entities pay wages in Australia add those wages to your total.
Sixth, if your wages exceed the threshold register through QRO’s online portal within seven days after the end of the month when the trigger occurred and begin monthly lodgements. Consider voluntary disclosure if you are late.
Worked examples and simple calculations
The table below compares three scenarios to show how exemptions and group rules affect liability. All figures exclude GST.
| Scenario | Wages to employees | Payments to subcontractors | Exemption applies | Group wages | Tax outcome |
|---|---|---|---|---|---|
| Labour-only contractor works 200 days | 800 000 | 600 000 | None | 1 400 000 | Payroll tax payable on 100 000 dollars above threshold |
| Contractor supplies goods with minor install labour | 800 000 | 600 000 | Ancillary labour exemption | 800 000 | No payroll tax because contractor payments are exempt and total wages below threshold |
| Two entities in a group each pay 700 000 in wages and non-exempt contractor payments | 700 000 | 0 | None | 1 400 000 | Payroll tax payable on 100 000 dollars above threshold across the group |
Calculating tax on the first scenario
Total Australian taxable wages 1 400 000 dollars Threshold 1 300 000 dollars Taxable amount 100 000 dollars Tax at 4.75 percent 4 750 dollars per year Monthly liability roughly 396 dollars
This example shows how a single contractor arrangement can flip a business from nil payroll tax to a recurring monthly obligation.
Frequently asked questions
Do subcontractor payments count toward Queensland payroll tax
Yes. If the contract is a relevant contract and no exemption applies, every dollar you pay to the subcontractor counts as taxable wages.
What is the current Queensland payroll tax threshold
The annual threshold is 1.3 million dollars in Australian taxable wages for the financial year. The figure is prorated for part year employers.
How do I know if a contractor is really an employee
Consider control over the work, integration into your business, ability to delegate, ownership of tools and exposure to profit or loss. If in doubt seek professional advice or apply for a ruling.
Can one exemption cover all contractor payments
Yes. You need only one exemption for the entire payment stream under that contract. However, you must keep evidence to prove the exemption applies.
Does the threshold apply to each company separately
No for grouped entities. If your business forms part of a payroll tax group you combine the Australian taxable wages of every member when testing the threshold.
Is payroll tax the same as the ATO taxable payments reporting system
No. Payroll tax is a state-based tax administered by the Queensland Revenue Office, while the taxable payments annual report is a federal reporting obligation to the Australian Taxation Office.
When must I register once I go over the threshold
You must register within seven days after the end of the month in which your Australian taxable wages first exceed the weekly equivalent trigger as published by the Queensland Revenue Office.
Are payments to interstate contractors included
Yes if the work has sufficient nexus with Queensland, for example, the services are performed in Queensland or the contractor is paid in Queensland.
What records do I need to keep for exemptions
Invoices, contracts, rosters, timesheets, proof of other clients, proof of materials supplied and any calculations of days or percentages. Keep these for at least five years.
What penalties apply for late registration or underpayment
Unpaid tax interest accrues daily. Penalty tax can reach up to twenty percent and more if the Commissioner finds intentional disregard or hindrance. Voluntary disclosure can reduce penalties.
Queensland payroll tax on contractor payments catches many businesses off guard. By understanding the relevant contract rules, checking the nine exemptions and monitoring your combined wage bill you can avoid nasty surprises and keep your cash flow healthy. If you think your subcontractor spend might tip you over the threshold act early, review your records and seek professional guidance to protect your business.
