Work-related car expenses are one of the most commonly claimed deductions in Australia. Understanding the difference between the cents per kilometre method and the logbook method can save you thousands. Here's everything you need to know.
Key Takeaways for 2024-25 Financial Year
- 1. Cents per km: 85 cents per kilometre, maximum 5,000 km per year
- 2. Logbook method: Claim actual expenses based on business use percentage
- 3. Commuting: Travel between home and regular workplace is NOT deductible
- 4. Car limit: $68,108 depreciation cap for 2024-25 (luxury car limit)
What Counts as Work-Related Car Travel?
Before claiming any vehicle deductions, you must understand what the ATO considers work-related travel. Not all driving for work is deductible.
Deductible Travel
- Travel between two separate workplaces
- Travel from your workplace to a client meeting
- Travel to attend conferences or training
- Carrying bulky tools (no secure storage at work)
- Travel for work tasks (sales calls, site visits)
- Travel between home and work when on-call
- Travel when your home is your base of operations
NOT Deductible
- Normal commute: home to regular workplace
- Private trips during work hours
- Travel where transport is provided by employer
- Travel expenses already reimbursed
- Driving to buy lunch
- Detours for personal errands
- Travel when you choose to drive (not required)
Bulky Tools Exception
You can claim home-to-work travel if you carry bulky tools or equipment that cannot be securely stored at your workplace. However, you must actually use these tools for work, and carrying them must be a genuine requirement (not just personal convenience). Examples include tradies with heavy power tools, musicians with large instruments, or photographers with extensive equipment.
Method 1: Cents Per Kilometre
The cents per kilometre method is the simpler option. You claim a flat rate for each business kilometre traveled, up to a maximum of 5,000 km per year.
2024-25 Cents Per Km Rate
85c
per kilometre (up to 5,000 km)
Max: $4,250
When to Use Cents Per Km
- You drive less than 5,000 business km per year
- You want simple record-keeping (no logbook required)
- Your car running costs are low
- You don't want to track individual expenses
Records Required
While simpler than the logbook method, you still need records to prove your business travel:
- Diary entries of business trips (date, destination, purpose, km)
- Calendar entries showing client meetings
- Evidence of work locations visited
Calculation Example
Example: Sales Representative
| Client visits (average 80 km/week x 48 weeks) | 3,840 km |
| Travel between office and warehouse | 960 km |
| Training course attendance | 200 km |
| Total business km (capped at 5,000) | 5,000 km |
| Tax Deduction (5,000 x $0.85) | $4,250 |
Method 2: Logbook Method
The logbook method allows you to claim the actual costs of running your car based on the percentage of business use. While it requires more record-keeping, it can result in significantly higher deductions if you have high running costs or travel more than 5,000 business km.
How the Logbook Method Works
- Keep a logbook for a continuous 12-week period
- Calculate business use percentage from the logbook
- Apply that percentage to all car expenses for the year
- Update logbook every 5 years or when circumstances change
Expenses You Can Claim
| Expense Category | Examples | Records Needed |
|---|---|---|
| Fuel & Oil | Petrol, diesel, LPG, oil changes | Receipts or credit card statements |
| Registration | Annual registration fees | Registration notice |
| Insurance | Comprehensive, third party, CTP | Insurance policy/receipt |
| Repairs & Servicing | Mechanical repairs, servicing, tyres | Invoices and receipts |
| Interest on Car Loan | Interest charges on finance | Loan statements |
| Lease Payments | Car lease or novated lease | Lease agreement, statements |
| Depreciation | Decline in value of vehicle | Purchase receipt, car limit applies |
Logbook Requirements
Your Logbook Must Record:
- Start date and odometer reading
- End date and odometer reading
- Date of each trip
- Odometer reading at start of trip
- Odometer reading at end of trip
- Kilometres traveled
- Purpose of trip (business or private)
- Name of business client/location visited
- Must cover continuous 12-week period
- Keep original logbook for 5 years
Logbook Calculation Example
Example: Tradesperson with Ute
Logbook Results (12 weeks):
- Total km driven: 6,000 km
- Business km: 4,200 km
- Business use percentage: 70%
| Annual Expense | Total Cost | Business (70%) |
|---|---|---|
| Fuel | $6,500 | $4,550 |
| Registration | $800 | $560 |
| Insurance | $1,800 | $1,260 |
| Servicing & repairs | $2,400 | $1,680 |
| Depreciation ($55,000 ute @ 25%) | $13,750 | $9,625 |
| Car loan interest | $2,800 | $1,960 |
| Total Vehicle Deduction | $28,050 | $19,635 |
Compare to cents per km: 5,000 km x $0.85 = $4,250. The logbook method saves $15,385 more!
Car Depreciation Rules
Vehicle depreciation is often the largest component of a logbook claim. The ATO has specific rules:
| Rule | 2024-25 Amount | Notes |
|---|---|---|
| Car Limit (Luxury Car) | $68,108 | Maximum depreciable cost |
| EV/Hydrogen Car Limit | $89,332 | Higher limit for zero emissions |
| Effective Life | 8 years | For cars (ATO determination) |
| Prime Cost Rate | 12.5% p.a. | Straight line method |
| Diminishing Value Rate | 25% p.a. | Higher early deductions |
Depreciation Example
Car purchased: $75,000 (exceeds car limit)
Depreciable amount: $68,108 (capped at car limit)
Prime Cost Method (12.5%)
Year 1: $68,108 x 12.5% = $8,514
Years 2-8: $8,514 per year
Diminishing Value (25%)
Year 1: $68,108 x 25% = $17,027
Year 2: $51,081 x 25% = $12,770
Which Method Should You Choose?
Decision Guide
Choose Cents Per Km if:
- Business travel is under 5,000 km per year

Quick Comparison
| Scenario | Cents Per Km | Logbook (60%) | Better Method |
|---|---|---|---|
| Old car, 3,000 km/year | $2,550 | ~$1,800 | Cents/Km |
| New car ($60k), 8,000 km/year | $4,250 (capped) | ~$12,000 | Logbook |
| Ute for trades, 15,000 km/year | $4,250 (capped) | ~$18,000 | Logbook |
Common Mistakes to Avoid
ATO Audit Red Flags
- x Claiming commuting: Home to regular workplace is never deductible
- x Exactly 5,000 km: Round numbers suggest estimates, not actual records
- x No logbook: Claiming logbook method without maintaining one
- x 100% business use: Very few people have 100% business use
- x Claiming reimbursed expenses: Already paid by employer
- x Both methods: You can only use one method per car per year
Motorcycles, Vans, and Other Vehicles
The rules differ for vehicles that aren't "cars" (vehicles designed primarily to carry passengers with a carrying capacity of less than 1 tonne and fewer than 9 passengers including the driver):
Motorcycles
- Cannot use cents per km method
- Must use actual costs method
- Keep receipts for all expenses
- Calculate business use percentage
Utes, Vans, Trucks (>1 tonne)
- Not subject to car limit
- Full cost can be depreciated
- May qualify for instant asset write-off
- Use actual costs method
