Quick summary
  • The ATO's draft guidance clarifies how to calculate superannuation guarantee obligations for contractors treated as employees under the extended SG rules. 
  • Businesses may need to separately identify labour and non-labour components of contractor payments and maintain stronger supporting documentation. 
  • With Payday Super now in effect, reviewing contractor arrangements and SG calculation processes is essential to reduce compliance risk and potential penalties.
Off the back of the updates on Payday Super focusing on Sports Persons and Entertainers* and contractors more broadly**, the ATO has released Draft Superannuation Guarantee Determination SGD 2026/D1, providing an overview of on how to calculate superannuation guarantee (SG) obligations for certain contractors.

While the draft ruling focuses on how superannuation obligations should be calculated, the recent updates highlight the ATO’s continued focus on contractor arrangements. With Payday Super set to increase compliance obligations, businesses should review their existing arrangements. 

A quick recap: why can contractors be entitled to super?

Many businesses are surprised at the breadth of the operation of the SG law, which applies to genuine contracting arrangements that may otherwise not create obligations from a Fair Work or broader employment tax law perspective.

Under the Superannuation Guarantee (Administration) Act 1992, a worker can still be treated as an employee if they are engaged under a contract that is wholly or principally for their labour. This is commonly referred to as the ‘extended definition’ of employee.

In our recent articles, we highlighted that these rules could apply across a broad range of industries and engagement models, including independent contractors, entertainers, sportspeople and influencers.

Once the obligation is established, the next challenge is identifying which payments under a contract are subject to SG, and which are excluded.

What does SGD 2026/D1 say?

The draft determination focuses on how to calculate a contractor's ‘qualifying earnings’, where the contractor is treated as an employee under the extended SG rules. 

The ATO's view is that qualifying earnings include payments that are ‘in respect of the person's labour’ under the contract.

Importantly, the ATO acknowledges that contractor invoices often bundle together multiple components, such as labour, equipment and tools, materials and consumables, travel expenses, GST payable, and other reimbursable costs. 

Under the draft guidance, businesses must identify the portion of a payment that relates to labour, and calculate SG on that amount. Payments that genuinely relate to equipment, materials or other non-labour components would generally not form part of qualifying earnings.

Why is this important?

Historically, many businesses have adopted a simple approach of either paying SG on the entire invoice, or simply not paying SG at all. 

The ATO's draft guidance introduces a more nuanced approach.

Where the labour component is clearly identifiable, businesses should use that amount. However, where labour and non-labour components are not separately identified, the ATO expects businesses to determine a reasonable value for the labour component. The draft determination provides examples of using market rates or industry award rates to estimate labour where necessary.

This means businesses may need more detailed supporting documentation than they have historically maintained.

A practical example

A contractor invoices:

  • $1,500 for services performed
  • $300 for specialised equipment use, and
  • $200 for materials.

Under the ATO's draft approach, SG would generally apply to the labour component of $1,500, but not to the equipment or material components, provided those amounts genuinely represent separate non-labour costs.

However, if the contractor simply issues a single invoice for $2,000 without any breakdown, the business may need to establish a reasonable methodology to determine how much of the payment relates to labour.

Why Payday Super changes the risk profile

The timing of this guidance is significant for any businesses with contractor engagements.

Under Payday Super, employers will generally be required to pay SG much closer to the date wages are paid. This will reduce the ability to identify and correct issues before reporting periods end.

For contractor arrangements, businesses will increasingly need to determine:

  1. whether a contractor falls within the extended definition of employee, and
  2. if so, what proportion of payments are subject to SG.

Getting this wrong could result in SG shortfalls, or Superannuation Guarantee Charge liabilities, penalties and interest.

What should businesses do now?

Businesses that engage contractors should consider:

  • Reviewing contractor arrangements
    • Assess whether any contractors may be covered by the extended employee provisions.
  • Reviewing invoicing practices
    • Determine whether labour and non-labour components are clearly identified within invoices and contracts.
  • Evaluating SG calculation methodologies
    • Where invoices contain bundled amounts, consider whether there is a documented and reasonable basis for identifying the labour component.
  • Ensuring Payday Super compliance
    • Ensure payroll, finance and procurement teams understand how contractor SG obligations will be managed in a real-time compliance environment.

Key takeaway

The release of SGD 2026/D1 is another reminder that contractor superannuation remains a significant compliance risk area. While the draft guidance does not change the underlying law, it provides valuable insight into how the ATO expects businesses to calculate SG obligations where contractors are captured by the extended employee provisions.
