Understanding Motor Vehicle Deductions
For Individuals
Individual taxpayers can claim motor vehicle expenses for work-related travel, but personal use cannot be claimed. The ATO offers two methods:
1. Cents per kilometre method
- Claim up to 5,000 business kilometres per vehicle
- Current rate: 85 cents per kilometre (2024-25 financial year)
- No receipts required for fuel and maintenance
- Must keep a record of business kilometres travelled
2. Logbook method
- No limit on business kilometres
- Claim actual expenses based on business use percentage
- Requires comprehensive record-keeping
- More complex but potentially higher deductions
For Businesses
Businesses can claim motor vehicle expenses using:
- Actual cost method: Claim all business-related vehicle expenses
- Cents per kilometre: Same rate as individuals, but with different record requirements
- Depreciation: For owned vehicles, claim depreciation over the asset's effective life
Essential Record-Keeping Requirements

The ATO provides guidance through ato.gov.au, the Small Business Support Line (13 28 66), and Online Services for individuals and businesses. For complex situations, a registered tax agent provides advice tailored to your specific circumstances and professional indemnity protection. You can verify agent registration at the TPB register at tpb.gov.au.
Most tax records must be kept for five years from the date of lodgement or the date the transaction occurred, whichever is later. Records must be in English or convertible to English and must be sufficient to explain the income and deductions in your return. The ATO can request records at any time during the retention period.
Consider a registered tax agent when your affairs involve multiple income sources, business activity, investment properties, capital gains, or overseas income. Agents extend your lodgement deadline, provide safe harbour protection, and take professional responsibility for the advice given. Verify registration at tpb.gov.au.
The failure to lodge penalty is based on penalty units ($313 per unit from 1 July 2023), accruing per 28-day period for late returns and BAS lodgements. Incorrect information penalties range from 25% to 75% of the tax shortfall depending on whether the behaviour was careless, reckless, or intentional. Proactive disclosure before an audit begins typically results in significantly reduced penalties.
Tax minimisation is the legal arrangement of your affairs to reduce tax — claiming all eligible deductions, using appropriate structures, and timing income and expenses. Tax avoidance involves arrangements that technically comply with the law but achieve outcomes parliament did not intend. The ATO can apply Part IVA anti-avoidance rules to cancel benefits from avoidance arrangements.
