In Australia, tax offsets and targeted tax concessions are designed to reduce the amount of tax payable for eligible individuals. These measures apply across different areas of the tax system, including personal income tax and indirect taxes such as goods and services tax (GST). For people with disability and veterans with disability, specific concessions exist in relation to car purchases, leases, and certain vehicle modifications. Understanding how these provisions work can help individuals determine what support may be available under Australia’s tax framework.
What Is a Tax Offset?

GST Car Concessions for People with Disability
Australia’s GST law provides car-related concessions for eligible working people with disability and veterans with disability. These concessions may apply when purchasing or leasing a new or used car or when buying certain car parts. For GST purposes, a car is defined as a motor vehicle that carries less than one tonne or fewer than nine passengers.
Eligibility must be established before claiming the concession, and a completed declaration must generally be provided to the supplier. A veteran with disability may qualify under more than one eligibility category, depending on their circumstances.
Eligibility for Working People with Disability

Exceptions and Gainful Employment Rules
The GST concession cannot be claimed if the car is purchased jointly with another person, leased under a full novation arrangement, or where the GST-inclusive market value exceeds the car limit, excluding eligible modification costs. The concession is also unavailable if the individual is not in gainful employment, is only seeking work, is a volunteer, a student, a pensioner, or retired.
Gainful employment includes regular paid work or operating a business that is profitable or has the purpose and prospect of profit.
Veterans with Disability: GST Concession Access
Veterans with disability may qualify for a GST car concession if they intend to use the car for personal transport for at least two years or until the car has travelled 40,000 kilometres. Eligibility is linked to service in the Australian Defence Force or another Commonwealth armed force and specific disability-related conditions, including loss of limbs or receipt of certain disability pensions.
Medical eligibility can be demonstrated through a Veteran Gold Card embossed “TPI” or a confirmation letter from the Department of Veterans’ Affairs. Eligible veterans may also apply for rebates on motorcycles and motorcycle parts using approved forms.
GST Refunds, Leasing, and Novation Arrangements
If GST was charged because a declaration was not provided at the time of purchase, a refund may be requested directly from the supplier once the declaration is completed. Under GST law, a direct refund from the tax authority is not available.
Eligible individuals may lease a car GST-free if the minimum time or distance conditions are met. Under partial novation arrangements, the concession may apply. Under full novation arrangements, where the employer leases the car, the GST concession does not apply.
Luxury Car Tax Considerations
Australia’s tax law does not provide a general exemption from luxury car tax for people with disability or veterans with disability. However, the value used to calculate luxury car tax excludes the cost of modifications made solely to adapt the car for disability-related use. Cars specially fitted for wheelchair transport may not be classified as luxury cars in certain circumstances.
Summary
Australia’s tax system includes tax offsets that reduce personal tax payable and specific GST car concessions designed to support people with disability and veterans with disability. While these measures can significantly reduce tax costs, eligibility depends on medical certification, employment status, car usage, and the structure of any lease or novation arrangement. Understanding the conditions, exclusions, and application process is essential to accessing these concessions correctly and in line with Australian tax law.
