A financially binding commitment is an agreement that obligates a party to continue a transaction without an easy way to withdraw. In the context of PHEVs, this means that if an employer has entered into a lease or purchase agreement before 1 April 2025, and this agreement remains unchanged, the FBT exemption can still apply.

The Australian Taxation Office (ATO) has clarified that a financially binding commitment must:

• Be legally enforceable and not easily revoked.
• Specifically relate to the private use of the vehicle by a designated employee or their associate.

Examples of qualifying agreements include:

• A signed purchase contract for a PHEV.
• A novated lease agreement that remains unchanged.

However, certain changes after 1 April 2025 could trigger a new commitment and result in an FBT liability, such as:

• Extending a lease agreement.
• Changing financial obligations (e.g., adjusting lease payments or residual values).
• Transferring employment to a new employer within a corporate group.

For businesses that provide PHEVs as part of their fleet, this change could have significant tax implications. Employers will be responsible for any FBT liabilities arising from 1 April 2025, and in some cases, these costs may be passed on to employees under salary packaging arrangements.

Employers with pooled PHEVs should take particular note—if a vehicle is not assigned to a specific employee under a binding agreement before 1 April 2025, it will likely lose its FBT exemption.

To prepare for these changes, businesses should consider the following actions:

• Review existing PHEV agreements: Ensure that any eligible agreements are in place before 1 April 2025.
• Assess FBT liabilities: Identify which vehicles will lose their exemption and estimate the financial impact.
• Update internal policies: Consider adjustments to vehicle leasing or fleet management strategies to minimise tax exposure.
• Plan for vehicle transitions: If switching from PHEVs to fully electric vehicles, factor in any additional costs, such as charging infrastructure, which may also have FBT implications.
