Deductions Denied for Intra-group Transactions Lacking “Substance”

Takeaways:

  • In Commissioner of Taxation v SNA Group, even though SNA Group had a services agreement in place, the court focused on what actually happened in practice. Because the conduct didn’t align with the agreement, the deductions were denied. 

  • The court found there was no real evidence of mutual assent (a genuine agreement between parties). Without that, there was no enforceable obligation to pay—so no tax deduction.

  • The ATO is increasingly willing to challenge intra-group arrangements—especially where fees appear to be set arbitrarily or after the fact without clear justification. 

  •  It’s not enough to sign an agreement. Businesses must support transactions with evidence (timesheets, calculations, methodology) and ensure actual behaviour matches the contract. 

 

Deductions Denied for Intra-group Transactions Lacking “Substance”

The Commissioner of Taxation achieved a significant result in a Full Federal Court decision in February 2026.

In Commissioner of Taxation v SNA Group, the court held that the taxpayer should be denied deductions for services paid to related parties. The court reasoned that there was no objective evidence of mutual assent (a meeting of minds). It was held that in the absence of mutual assent there was no contractual obligation for the payment of a service fee and the deductions were denied.

The structure in the SNA Group was very typical of a real estate business: SNA Group operated a real estate management business, it paid service fees to related party trusts that held the rent roll assets, intellectual property and employees. The SNA Group used the assets and services provided by these trusts.

Man-Looking-Out

Background & Why This Matters

The Full Federal Court decision has reinforced a critical principle for business owners and corporate groups: tax deductions will not be allowed where intra-group transactions lack genuine commercial substance and proper documentation.

In Commissioner of Taxation v SNA Group, the Court sided with the Commissioner of Taxation, denying deductions for service fees paid between related entities. The case is significant because it highlights the growing scrutiny from the ATO—and the Courts—on how businesses structure and evidence transactions within their own groups.

For many SMEs and corporate groups that operate across multiple entities, this decision serves as a clear warning: treating the group as “one business” is not enough—each entity must stand on its own legal footing.

The “Substance” (or Lack Thereof)

SNA Group and the trusts had previously executed a services agreement. This agreement stated that a service fee can be charged by the trust for the use of IP, rent roll and employees. The amount of the service fee would be determined each year but should not exceed 8% of the group’s net assets at market value. However, the accounts showed a significant departure from the services agreement (including two years where the fee exceeded 8%). The parties involved in the transactions were the controlled by the same directors, their evidence lacked substance in how the service fee was determined and ultimately it appeared as though the accountant merely determined the amount after the year end and journalled the service fee.

As a personal highlight in the case, oral evidence included the verbatim statement:

“we used to call our meetings at the Chinese restaurant – our – our unit holder meetings, and we would say – he would say, “This is what the charge is going to be.” We would think it would be fair and reasonable.”

Ultimately, the court took issue with the substance of the transaction, there was no corroborative evidence to suggest how the quantum of the service was determined.

The ATO will take a position to deny deductions for intra-group transactions in the absence of documentation, that matches conduct, or sufficient evidence to rationalise the obligations of the parties. The Courts have supported the ATO in this decision. It is a recognition that contract law and documenting corporate decisions should impact tax outcomes. Whilst corporate groups treat the business as a single unit, companies are artificial but separate legal personalities. Separate legal personalities need to show the elements of a contract are met to have an obligation to pay. For this reason the Full Court stressed the issue that entities of the same business group must still show mutual assent to create a legal obligation to pay.

The SME client base often have issues with documenting intra-group transactions. It is an added compliance cost to a business owner who is concentrating on running their business. However, services agreements are important documents that may cover a range of activities. Services agreements should be supported by extrinsic evidence e.g. staff timesheets, project codes or documenting proprietary use. This decision has further ramifications when considering corporate groups regularly utilise payments by direction, assignments and set-off: these transactions should be documented and the appropriate legal evidence should form part of the execution of these transaction.

The execution of a legal agreement is only the initial step and clients should also establish systems and processes, which are documented, to have an easier time supporting intra-group transactions in the event of an audit or review.
