Paying contractors in Australia in 2026: Rules and misclassification risk

Paying contractors in Australia requires businesses to consider worker classification, superannuation, tax withholding, GST and state-level obligations. Under the Fair Work Act, contractor status depends on the real substance and practical nature of the working relationship, including how the contract operates in practice. Having an Australian Business Number (ABN) or a contractor agreement does not automatically establish independent contractor status.

For foreign companies engaging Australian contractors, payment arrangements must also account for applicable superannuation contributions, Pay As You Go (PAYG) withholding, payroll tax and workers’ compensation requirements.

Each follows different rules, meaning a worker may qualify as a contractor under one regime but an employee under another. Assessing these obligations before making payments helps businesses manage compliance and reduce misclassification risks.

Collect the contractor’s identity and tax details before you pay the first invoice. These records are the evidence a payer relies on if a classification or withholding decision is questioned later.

• Legal name and entity type: individual, company, trust or partnership.
• The Australian Business Number (ABN), the identifier businesses quote on invoices, checked in the public ABN Lookup register, with a dated record.
• Registration status for Goods and Services Tax (GST), Australia’s 10% consumption tax, also from ABN Lookup.
• Bank details matched to the contracting party.
• The state or territory where the work is performed.
• A statement of work with deliverables and acceptance criteria.

An ABN identifies a business. It is not evidence of contractor status, which is why the tests below look at how the work is done.

Since 26 August 2024, section 15AA of the Fair Work Act 2009, the federal law that sets minimum employment terms, requires classification by the relationship’s “real substance, practical reality and true nature”. The decision-maker considers the written contract and how it is performed in practice. The Closing Loopholes Act inserted the provision in response to two 2022 High Court decisions, Personnel Contracting and Jamsek, which had made a valid written contract the main evidence.

The test generally applies to a “constitutionally covered business”, a group that includes foreign corporations. A foreign company that engages an individual directly ordinarily falls into that group. Section 15AA governs Fair Work Act classification. Tax, superannuation, payroll tax and workers’ compensation keep their own definitions. For withholding and super, the Australian Taxation Office (ATO), the federal tax authority, still starts from the legal rights and obligations in the contract.

Sham contracting is narrower than accidental misclassification. Section 357 of the Fair Work Act prohibits an employer from representing an employment contract as an independent contracting arrangement. Since 27 February 2024, the employer’s defence is to prove it reasonably believed, when it made the representation, that the contract was for services. Evidence can include the hirer’s experience, advice obtained, industry practice and how the relationship operated. A contractor label or an ABN alone cannot establish a reasonable belief.

Maximum penalties for sham contracting are set in penalty units. For offences from 1 July 2026, one unit is AUD 364 under the 2026 penalty unit instrument, so 60 units for an individual comes to 60 × AUD 364, which is AUD 21,840.

The cut-off follows section 23 of the Fair Work Act, which defines a small business employer as one with fewer than 15 employees.

Yes, if the contract is wholly or principally for the contractor’s labour. Superannuation, Australia’s compulsory employer-funded retirement saving, applies its own test. Under section 12(3) of the Superannuation Guarantee (Administration) Act 1992, an individual working under such a contract is an employee for superannuation guarantee (SG) purposes. That holds even for a contractor with an ABN. The ATO looks for three indicators:

1. The individual is paid mainly for personal labour and skills.
2. The individual must do the work personally.
3. The individual is paid for hours worked rather than for a result.

The contract must be with the individual directly. After JMC Pty Ltd v Commissioner of Taxation [2023] FCAFC 76, the ATO’s view is that a legally effective right to delegate or subcontract takes a contract outside section 12(3).

The SG rate has been 12% since 1 July 2025. For earnings paid from 1 July 2026, Payday Super generally requires contributions to reach the fund within 7 business days after each payday, subject to exceptions. For a contractor covered by section 12(3), SG applies to the labour component of each invoice, excluding separately identified materials, equipment and GST. On an illustrative AUD 10,000 invoice before GST that includes AUD 2,000 of equipment, the labour component is AUD 10,000 minus AUD 2,000, or AUD 8,000. Twelve per cent of AUD 8,000 is a contribution of AUD 960.

Late, short or misdirected contributions trigger the super guarantee charge (SGC), which costs more than the unpaid 12%, plus possible interest, a penalty of up to 200% of the SGC and director penalties. Payday Super changed the SGC calculation from 1 July 2026, so check the operative rules for the affected period.

Pay As You Go (PAYG) withholding is the system under which Australian payers deduct tax from certain payments. Where a payer is within that system and a supplier who should quote an ABN does not, the payer generally withholds 47% of any payment over AUD 75 excluding GST. On an illustrative AUD 2,000 invoice, 47% is AUD 940, so the supplier receives AUD 1,060. Whether an offshore payer with no Australian enterprise, registration or presence falls within PAYG withholding depends on its own facts, so take advice first.

A contractor generally must register for GST within 21 days of GST turnover reaching AUD 75,000. Exported services can be GST-free where statutory conditions are met, such as a supply to a non-resident outside Australia who uses the service outside Australia.

The Taxable Payments Annual Report (TPAR), an annual ATO report of contractor payments, may apply to building and construction, cleaning, courier, road freight, IT, and security, investigation or surveillance services. It is generally due on 28 August. Whether a foreign company must lodge depends on whether it carries on one of those businesses, holds an ABN and meets the income tests for that industry.

Payroll tax is a state and territory tax on wages. Under “relevant contract” provisions, contractor payments can be taxed as wages even where federal law treats the worker as a contractor. Thresholds apply to grouped Australian wages, so a foreign group’s ownership structure matters. Common exclusions:

Exceeding the 90-day limit can expose all payments for the year. For an illustrative contractor engaged for 100 days, the exposure can cover all 100 days, not the 10 days over the limit.

The other states and territories set their own figures, which need checking alongside the wider Australian employer taxes a foreign group has to model.

Each state and territory has its own workers’ compensation scheme, and its definitions can reach beyond employees. In Victoria, a sole trader, partner or incorporated service provider can be a deemed worker of the principal. Their remuneration can then count towards WorkCover premiums, Victoria’s workers’ compensation insurance. Other states apply their own tests, so check the scheme for each work location before engaging.

Payment from a foreign bank account does not decide classification. If the foreign hirer controls daily work and requires personal ongoing service, the relationship may be employment regardless of where the money comes from. A cross-border payment process has five steps:

1. Contract with the legal entity named on the ABN record.
2. Validate the ABN, GST status and bank account ownership before the first payment.
3. Obtain an invoice that separates labour from materials where super could apply.
4. Apply any Australian withholding that legally attaches to the payer.
5. Keep records of deliverable approval, currency conversion, deductions and remittance.

A foreign company carrying on business in Australia may also have to register with the Australian Securities and Investments Commission (ASIC), the corporate regulator, and appoint a local agent.

If a contractor is found to be an employee, the hirer may owe the National Employment Standards (NES), the statutory minimum entitlements. It may also owe the terms of any modern award (the industry-level minimum pay rules) or enterprise agreement, covering minimum wages, overtime, leave, notice, redundancy pay and super. Underpayment proceedings generally have a six-year limitation period. The Fair Work Ombudsman, the federal workplace regulator, expects remediation reviews to look back at least six years where the issue may have persisted. The cost of employee misclassification can also include the SGC, PAYG assessments, retrospective payroll tax and workers’ compensation premiums.

From 1 January 2025, intentional underpayment can be a federal criminal offence under a separate provision from the sham contracting rules. Honest mistakes are excluded. Section 327A(6) sets the maximum penalties, shown here for offences on or after 1 July 2026:

• A company: AUD 9.1 million (25,000 penalty units at AUD 364) or three times the underpayment, whichever is greater.
• An individual: up to 10 years’ imprisonment, a fine of AUD 1.82 million (5,000 penalty units) or three times the underpayment, whichever is greater, or both.

For a company that intentionally underpaid an illustrative AUD 4 million, three times that is AUD 12 million. AUD 12 million is greater than AUD 9.1 million, so it becomes the maximum fine. Anyone knowingly maintaining a sham arrangement should seek legal advice immediately.

Because section 15AA weighs how the work happens day to day, the Australian decision depends on how each role operates. A specialist delivering a defined project through an independent business can remain a contractor. A person with fixed hours, employees to manage and no end date points strongly towards employment, whatever the contract says.
